Description

  The present invention relates to a management system for housing equipment.

  In general, a plurality of equipment is installed in a house, and electric power is consumed as each equipment is operated as necessary. Here, for example, when each facility device is operated by supplying commercial power, the total power used, which is the total amount of power used in the house, is restricted by the contract power (maximum power demand). Moreover, even if it is a case where electric power (solar power generation power etc.) other than commercial power is used, it is the same that restrictions are imposed on the usable electric power.

  As a technique for restricting excessive electric power use in a house, a technique for restricting electric power use for each facility equipment has been proposed. For example, in the power storage control device of Patent Document 1, regarding power storage of a power storage unit mounted on a vehicle, a power supply current value supplied to a device other than the power storage unit is subtracted from a maximum allowable allowable current value based on contract power, and the subtraction is performed. Electric power is stored in the electric storage means with a current within a range whose value is the upper limit. In addition, when the device has a heat pump device and prioritizes the power storage of the power storage device over the operation of the heat pump device, the operation of the heat pump device is prohibited when starting the power storage of the power storage device, and after the power storage of the power storage device is completed The prohibition of operation of the heat pump device is canceled.

  However, if the priority of operation is determined in advance for each equipment device installed in the house, even if the usage situation and usage needs by the resident change from day to day, control according to it is not possible, There was a risk that the resident would be unable to use the equipment. In other words, in the actual life in a house, the usage status and usage needs of each equipment in the house change from day to day.For example, the usage status of equipment equipment yesterday and today's usage status are the same time. May be different. For this reason, there is a possibility that the usability of each facility device may be impaired, such as a restriction on use of the facility device that the resident originally wants to use.

  The present invention has been made in view of the above circumstances, and is capable of suitably controlling the operation of each equipment device while improving the usability for each equipment device provided in the house. The main purpose is to provide a device management system.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

The first invention is
A plurality of equipment provided in a house and operated by power supply from a power supply unit;
Control means for controlling the operation of each facility device;
A management system for housing equipment comprising:
Power calculating means for calculating the power supplied in the power supply unit;
When the supply power calculated by the power calculation means reaches a predetermined power upper limit value, any one of the plurality of facility devices based on the priority of operation determined in advance for the plurality of facility devices Limiting means to limit the driving of
Based on information on at least one of the usage status of each facility device and the resident's behavior, a change necessity determination unit that determines whether or not to change the priority order, and
A setting change unit for changing the setting of the priority when the change necessity determination unit determines that the change is necessary;
It is characterized by providing.

  Generally, in a house, when a plurality of facility devices are operated as necessary, the power supplied from the power supply unit (total power consumption P) is a predetermined value (for example, maximum demand power that is contract power in the case of commercial power). The power supply to each equipment is cut off due to the breaker being cut off. In this regard, according to the above configuration, when the power supplied from the power feeding unit reaches a predetermined power upper limit value, the operation of any of the equipment is limited based on a predetermined priority order. Therefore, it is possible to regulate the supply power so as not to exceed the predetermined power upper limit value, and it is possible to suppress inconveniences such as unintentional breaker interruption due to excessive power supply.

  Moreover, in the said structure, the setting change of a priority can be performed according to the use condition of each equipment, and a resident's action. Therefore, in the actual use of each equipment in a house, even if the usage status of each equipment and the behavior of the resident (including the use needs of the equipment accompanying the behavior) change, for example, every day, reflecting that It becomes possible to improve the usability by the residents. Thereby, it becomes possible to control operation of each equipment apparatus suitably.

  2nd invention is provided with the at-home determination means which determines who is resident among the residents of the said house in the said house, The said change necessity determination means is based on the at-home determination result by the said at-home determination means, It is characterized by determining whether or not the priority order needs to be changed.

  Which equipment is actually used (operated) in a house depends on who is the resident at home. Conversely, it depends on who is absent. In this respect, the operation of each equipment is suitably controlled in accordance with the actual situation of each resident's house by determining whether or not the priority needs to be changed based on the determination result of who is at home. it can. The at-home determination result by the at-home determination means corresponds to information on the behavior of the resident.

  3rd invention is equipped with the resident detection means to detect each resident's going home and going out, and the said home determination means determines who is resident among the residents based on the detection result by the said resident detection means It is characterized by doing.

  According to the said structure, based on the resident returning to a house and going out of a house, it can be determined whether each resident is at home or absent. In this case, the priority order can be changed when these return homes or outings are detected.

  The following configuration can be considered as at-home determination means (resident detection means). For example, an ID (resident ID) for each resident is used for a portable device such as an electronic key or a mobile phone carried by each resident, or a monitoring device (such as an electronic lock device) for monitoring the entrance and exit of a person at the entrance of a house entrance. It is good to use the structure which gives ID authentication function which authenticates, and determines who is a resident at home based on the resident ID in a house. Or, a position detection function is added to a portable device carried by the resident or a car used by the resident, and the resident's return / outing and the resident's home / absence are determined by the resident position obtained from the position detection function. It is also possible to determine.

  A fourth aspect of the present invention includes a charging facility for charging a power storage device mounted on an electric vehicle with the power supplied from the power supply unit as the plurality of facility devices, and determines a use schedule of the electric vehicle. Use schedule determination means is provided, and the change necessity determination means determines whether or not the priority needs to be changed based on a determination result of the vehicle use schedule by the use schedule determination means.

  In a house equipped with a charging facility for charging a vehicle, the amount of power supplied from the power feeding unit varies greatly depending on whether the charging facility is used. That is, the actual power margin in the house varies greatly. In this respect, by determining whether or not the priority order needs to be changed based on the determination result of determining the vehicle use schedule, it is possible to suitably control the operation of each facility device while making it correspond to the actual power margin.

  The charging facility is used (operated) depending on the degree of use of the electric vehicle. In this case, the determination result (scheduled use of the electric vehicle) by the use schedule determination unit corresponds to information on the usage status of the facility equipment (charging facility).

  As the use schedule determination unit, for example, a configuration may be used in which a use schedule for an electric vehicle is registered in advance and the use schedule of the electric vehicle is determined based on the use schedule. Or it is good to use the structure which memorize | stores the past use log | history sequentially about an electric vehicle, and determines the use plan of an electric vehicle by prediction based on the use log | history. For example, from the use history of the electric vehicle, it is predicted that the electric vehicle will not be used after the current time (for example, the next day), or even if the electric vehicle is used after the current time (for example, the next day), the travel distance is small. It is good to predict.

  The fifth invention includes, as the plurality of equipment, in addition to the charging equipment, hot water equipment that heats water by power supplied from the power feeding unit and stores hot water generated by the heating in a hot water storage tank. The setting change means is determined for the charging facility and the hot water facility when the change necessity determination means determines that the priority order needs to be changed based on the determination result of the vehicle use schedule. It is characterized in that replacement is performed with respect to mutual priorities.

  Charging facilities and hot water facilities consume a large amount of electricity among all equipment in a house. In a house equipped with both of these facilities, the power supplied from the power supply unit can be increased at a stretch by operating both facilities at the same time. There is a concern that power interruption will occur. Further, assuming simultaneous use of both of these facilities, a contract for large power is required as contract power (maximum demand power), resulting in inconvenience that the burden on the resident increases. Therefore, it is desirable to set mutual priority for both facilities.

  In this regard, according to the above configuration, the mutual priority of the charging facility and the hot water facility is determined, and the mutual priority can be appropriately interchanged. It is possible to suitably control the operation of the equipment according to the facility use needs each time, while suppressing inconveniences such as exceeding the power consumption or forcing the contract power to be increased.

  In a sixth aspect of the invention, one day is divided into a plurality of time zones, and the priority order of each facility device is determined for each time zone, and the limiting means is based on the priority order for each time zone. The operation of any one of the facility devices is restricted, and the setting change unit individually changes the setting for the priority order for each time zone.

  The plurality of facility devices provided in the house include devices that use different time zones. Therefore, when the priority of operation of each facility device is changed, it is not desirable that the change of the priority is performed regardless of the time zone. In this regard, according to the above configuration, since the priority order for each time zone is individually set and changed, it is preferable to control the operation of the equipment while taking into account that the time zones of use are different for a plurality of equipment. Can be implemented.

  7th invention is a management system of the housing equipment which has a home server provided in each of a plurality of houses, and a management server in which information communication is possible between these home servers, Driving priority data related to the priority order is registered as default data for each house in the management server, and the home server includes the restriction means, the change necessity determination means, and the setting change means. The operation priority order data is received from the management server, and the setting changing means changes the setting with respect to the priority order defined by the operation priority order data. .

  According to the above configuration, the driving priority data is registered as default data in the management server, and the home server receives the driving priority data (default data) from the management server as necessary and uses the data. To restrict the operation of equipment (restriction means). Further, the home server determines whether or not the priority order needs to be changed (change necessity determination unit), and when it is determined that the change is necessary, changes the priority order setting (setting change unit).

  In the above configuration, since the driving priority order data (default data) is managed on the management server side, it is not a setting change due to individual circumstances for each house, but when a uniform setting change is performed for a plurality of houses, For example, when driving priority data (default data) is changed for each season or for each region, the change can be performed simultaneously. Therefore, it is considered that it is advantageous in terms of management.

  In addition, when the setting change of the priority order for every house is implemented in the home server, the setting change is transmitted to the management server side, and the driving priority order data registered in the management server is based on the transmission data. (Default data) may be updated.

  8th invention is the management system of the housing equipment apparatus which has the home server each provided in the some house, and the management server in which information communication is possible between these each home server, The management server is capable of communicating with a mobile phone terminal carried by a resident, and the management server sends the control content of operation for each facility device in response to a request from the mobile phone terminal. It has a function of notifying the house side, and a function of receiving information on the operating state of each facility device from the house side and notifying the received information to the mobile phone terminal.

  According to the above configuration, both information transmission from the mobile phone terminal to the management server and vice versa can be performed from the management server to the mobile phone terminal. Therefore, even if the resident has gone out, the resident can control the operation of each facility device and monitor the operation state of each facility device at an arbitrary timing.

The monitoring signal includes a signal indicating that the charging cable 25b is connected to the electric vehicle C in addition to a signal indicating that the electric vehicle C is charged.

  In addition, the home 10 is provided with a home gateway device 27 that interconnects an in-house network built in the home 10 and a management network built around the management center 30. The home gateway device 27 is a communication relay device and is connected to the management center 30 via a communication line H2. The home gateway device 27 can wirelessly transmit and receive signals to and from the power monitoring device 16 and the communication units 21a to 25a.

  A home server 28 is connected to the home gateway device 27 via a LAN cable. The home server 28 is an arithmetic device having a microcomputer (microcomputer) composed of a CPU, various memories, and the like, and controls the operation state of each of the above facilities 21 to 25 (corresponding to a control means). In this case, the control command output from the home server 28 is transmitted from the home gateway device 27 to the communication units 21a to 25a of the facilities 21 to 25, and the facilities 21 to 25 are operated in response to the control command.

  Each of the above-mentioned facilities 21 to 25 is controlled by a control command (remote operation signal) input through each of the communication units 21a to 25a, and in addition, an operation panel ( When the user manually operates (not shown), the driving states are respectively operated.

  Moreover, in this embodiment, it is possible to operate the driving | running state of each installation 21-25 using the mobile telephone terminal 29 which the user for every house owns. The mobile phone terminal 29 is a multi-function mobile phone (so-called smart phone) having functions of a personal computer and a PDA (personal digital assistant), and predetermined application software related to the control of each equipment 21 to 25 is introduced into the mobile phone terminal 29 ( Installation) enables operation control of each of the facilities 21 to 25 by the mobile phone terminal 29.

  In addition, various home electrical appliances 26 are connected to the house 10 as electrical devices. The home appliance 26 includes electric products such as a television, an electric rice cooker, a dishwasher, a dryer, and an electric heater. Similarly to the above-described facilities 21 to 25, commercial power is supplied to the home appliance 26 via the electric wiring 15, and the home appliance 26 operates by the power supply. However, unlike the facilities 21 to 23, the home appliance 26 is not an HA-compatible device (has no HA terminal) and cannot be remotely operated or monitored by a home network.

  The management center 30 is connected to the plurality of houses 10 via the communication line H2. A management server 31 is provided in the management center 30. The management server 31 can mutually communicate information with each home server 28 of the plurality of houses 10. For example, the management server 31 is connected to each of a plurality of houses existing in a predetermined area as management targets. Alternatively, the management server 31 is connected to a plurality of houses constructed by a specific house maker and a construction contractor, or a house in which a specific home gateway device and a home server are installed, as a management target.

  In addition, the management center 30 receives various types of information from the mobile phone terminal 29 using the telephone network of the mobile phone terminal 29 owned by each user for each home 10, and for each home 10 based on the received information. Operation control etc. are implemented about each of these facilities 21-25. Specifically, when the resident operates the mobile phone terminal 29 while away from home and information on each of the facilities 21 to 25 is transmitted to the management server 31, the management server 31 uses the telephone network to transmit the transmission information. Receive. At this time, if a command for controlling the operation of any of the equipment devices (for example, the air conditioning equipment 22 and the hot water supply equipment 24) is received from the mobile phone terminal 29, the management server 31 passes the corresponding equipment via the home gateway device 27. Control the operation of the equipment. Alternatively, if a command to acquire the operating state of any equipment device is received from the mobile phone terminal 29, the management server 31 receives the operating state of the equipment device via the home gateway device 27, and sends it to the mobile phone. Return to terminal 29. In this case, the resident can operate the lighting equipment 21 and the air conditioner 22 (such as power on / off) even when away from home. In addition, it is possible to easily check the operating state of each of the facilities 21 and 22 and the locked / unlocked state of the electronic lock facility 23 when going out.

  Furthermore, when the operation state is changed in each of the facilities 21 to 25 for each house 10, the management center 30 receives operation information and the like via the home gateway device 27 each time the change is made, and the home gateway device. The reception information from 27 (each house 10) is transmitted to the mobile phone terminal 29 using the telephone network. Specifically, for example, when the electronic lock facility 23 is unlocked due to someone living in the house 10, the unlock information is immediately transmitted from the home gateway device 27 to the management server 31. Then, the management server 31 transmits the unlocking information to the resident mobile phone terminal 29 using the telephone network. At this time, even if the resident is away from home, it is possible to notify the resident of the door lock / unlock information of the house 10. The same applies when the operation switching of the air conditioning equipment 22 is performed in the house 10.

  By the way, in the house 10 to which commercial power is supplied by a contract with an electric power company or the like, the power used is limited within the range of contract power. In this case, if more equipment than expected is used at the same time in the house 10, there is a concern that the supply power will stop unintentionally (breaker will fall). In particular, when the hot water supply facility 24 and the charging facility 25 are provided as described above, the concern is increased by operating these facilities 24 and 25 simultaneously.

  The hot water supply operation of the hot water supply facility 24 and the vehicle charging by the charging facility 25 are basically performed in a predetermined night time zone (from 23:00 to 7:00 am). If other equipment and household appliances are used at the same time, it is possible that the total power used will reach the limit value.

  Therefore, in this embodiment, priorities are determined in advance for the operation (use) of the facilities 21 to 25 in the house 10, and the total power used in the house 10 is an allowable value (power upper limit value), for example, “contract power− When the power value of “α” is exceeded, the operation is stopped for any of the operating equipment (in use) according to the operation priority. As a result, the total power used in the house 10 is limited to a predetermined limit value or less (contract power or less).

  Which equipment is preferentially operated depends on the time of the day. Therefore, in setting the driving priority, the time zone of the day is taken into consideration. In FIG. 2, an example is shown about the driving | running priority of each installation 21-25 for every time slot | zone. Here, for convenience of explanation, the driving priority order will be described for the air conditioning facilities 22-1 to 22-3, the hot water supply facility 24, and the charging facility 25 in the living room, bedroom, and child room. However, it is also possible to set an operation priority order for all facilities including the lighting facility 21 and the electronic lock facility 23. Since it is not desirable for the lighting equipment 21 and the electronic lock equipment 23 to be powered off (stopped operation) regardless of the resident's intention, the driving priority may be set at the highest level. In FIG. 2, the priorities are shown as 1st to 5th. From 23:00 to 7:00 is a time zone in which cheap nighttime electricity can be used.

  “Time zone A” is a time zone from 7 o'clock to 10 o'clock, and in this time zone A, the operation of each of the air conditioning facilities 22-1 to 22-3 has priority over the operation of the hot water supply facility 24 and the charging facility 25. ing. In this case, if the total power used exceeds the contract power, the operation is stopped for the equipment with the lower priority among the equipment (equipment 22-1 to 22-3, 24, 25) that is currently operating.

  “Time zone B” is a time zone from 10:00 to 16:00, and in this time zone B, since the resident is going to school or work, it is considered that the power consumption in the house 10 is reduced. Therefore, no priority is set.

  “Time zone C” is a time zone from 16:00 to 21:00, and “Time zone D” is a time zone from 21:00 to 23:00. In these time zones C and D, like the time zone A, the operation of each of the air conditioning facilities 22-1 to 22-3 is given priority over the operation of the hot water supply facility 24 and the charging facility 25. In the time zones A, C, and D, it may be arbitrarily determined which of the air conditioning facilities 22-1 to 22-3 is to be given higher priority for operation. For example, a resident is present in the room. It is better to give higher priority to the air-conditioning equipment in the room where there is a high possibility.

  “Time zone E” is a time zone from 23:00 to 1 o'clock, and in this time zone E, the driving priority is assigned to the air conditioners 22-2 and 22-3 in the rooms (bedrooms and child rooms) where each resident sleeps. It is high.

  “Time zone F” is a time zone from 1 o'clock to 4 o'clock, and “time zone G” is a time zone from 4 o'clock to 7 o'clock. In these time zones F and G, the operation of the hot water supply facility 24 and the charging facility 25 is prioritized over the operation of the air conditioning facilities 22-1 to 22-3. Here, in particular, it is desirable that the water heater by the hot water supply facility 24 is carried out in accordance with the resident's wake-up time from the viewpoint of preventing the water from being cooled. It is good to be operated so that the water heating is completed. Therefore, in the time zone G, the operation priority of the hot water supply facility 24 is the highest. On the other hand, it is indispensable for the electric vehicle C to be charged by the vehicle user (for example, father) 's attendance time. If the charge is completed by the attendance time, the night time zone (23 Charging may be performed at any time of (hours to 7:00). For this reason, the operation priority of the charging facility 25 is set to the highest in the time zone other than the time zone G, here the time zone F.

  In addition, in each said time slot | zone, when the household appliances 26 are used according to a resident's convenience other than the facilities 21-25, it can happen that the total electric power used exceeds contract electric power by use of the household appliances 26. Conceivable. Also in this case, as the total power used exceeds the contract power, the operation is stopped for the facility with the lower priority among the facilities (equipment 21 to 25) that are currently operating.

  The number of residents staying at home during the daytime is different on weekdays when residents go to school or work and on weekends when school or work is closed, and the situation of which equipment is used in which time is different. . Therefore, the driving priority order may be different between weekdays and weekends. In this case, driving priority data for weekdays and driving priority data for holidays are prepared.

  Information related to the driving priority is registered in the management server 31 as driving priority data. And the home server 28 receives the driving | operation priority order data of the management server 31, as needed, and controls the driving | running state of each installation 21-25 with reference to the data.

  Moreover, in this embodiment, the information regarding the behavior of each resident and the usage status of each facility 21 to 25 is acquired, and based on the information, the setting change is appropriately performed for the driving priority of each facility 21 to 25. Yes. In other words, while controlling the driving state of each facility 21-25 based on the driving priority set as described above, the usage needs of each facility 21-25 based on the behavior of each resident, and the use of each facility 21-25. Based on the situation (operation history of each facility 21 to 25), it is necessary to change the priority for equipment with a low operation priority to the higher order, or vice versa. If it is determined that there is a need for a change, the driving priority order is changed.

  Specifically, the following configurations can be considered.

  It is determined who of the residents in the house 10 has come home, and based on the return home determination result (in other words, the home / absence determination result based on the home return determination result), it is determined whether or not it is necessary to change the driving priority. And when it determines with a change required, the setting change of a driving priority is implemented. Here, it can be determined from the ID code authenticated by the electronic lock facility 23 of the entrance door which resident has returned home and which resident has gone out in the house 10. In this case, the ID authentication function using the electronic lock facility 23 and the electronic key corresponds to the resident detection means. In addition, even if ID authentication is not performed by the electronic lock facility 23, if a resident authentication device such as a code authentication method or a biometric information authentication method is provided in the house 10, the determination of returning home / outing (at home / absence) is made for each resident. Is possible.

  In this case, for example, if it is determined that the child has returned home, the driving priority is increased for the air conditioner 22-3 in the child room, assuming that the driving priority needs to be changed. Further, if it is determined that the child has gone out, the driving priority is lowered for the air conditioner 22-3 in the child room, assuming that the driving priority needs to be changed. Thus, for example, when it is determined that the child has gone out (absent) in the time zones A, C, and D of FIG. 2, the operation of the hot water supply facility 24 and the charging facility 25 is performed in the air conditioning facility 22-3 in the child room. Priority is given to driving. That is, even if the air conditioner 22-3 in the children's room is operated while the child is away, if the power consumption by other devices increases, the operation of the air conditioner 22-3 is stopped before the other. It becomes. It is preferable that the operation priority order of each facility device is changed at the time when returning home or going out is detected for each resident.

  When it is determined from the ID of the electronic key that the child has returned home or has gone out, the parent mobile phone terminal 29 is notified that the child has returned home or has gone out and that the driving priority has been changed. Good.

  Moreover, the use plan of the electric vehicle C is determined, and whether or not it is necessary to change the driving priority order is determined based on the determination result. And when it determines with a change required, the setting change of a driving priority is implemented. Here, if it is determined that a resident (for example, a father) who mainly uses the electric vehicle C is absent, that is, the electric vehicle C is not used the next day, the electric vehicle C is parked in the house 10. The electric vehicle C need not be charged. In this case, it is assumed that the driving priority is changed for the charging facility 25 because it is necessary to change the driving priority. Thereby, for example, in the time zones F and G in FIG. 2, the operation of other devices is prioritized over the operation of the charging facility 25.

  In addition, although the electric vehicle C is connected to the charging facility 25, that is, ready for charging, the amount of charge per day is small (predetermined from the past implementation history of charging by the charging facility 25). If it is equal to or less than the predetermined amount), the operation priority of the charging equipment 25 in the time zones E to G is lowered to the lower order because it is necessary to change the operation priority. In this case, the operation of each air conditioning facility 22 has priority over the charging of the electric vehicle C by the charging facility 25.

  The use schedule of the electric vehicle C may be determined based on a use schedule registered in advance in the home server 28. Moreover, the structure which determines the use plan of the electric vehicle C by memorize | storing the past use log | history sequentially about the electric vehicle C, and the prediction based on the use log | history may be sufficient. For example, even if it is predicted from the use history of the electric vehicle C that the electric vehicle C is not used after the current time (for example, the next day), or even if the electric vehicle C is used after the current time (for example, the next day), the travel distance is slightly It is better to predict that.

  The charging history information regarding the charging facility 25 may be stored based on transmission information from the charging facility 25 to the home server 28 every time vehicle charging is performed every day. In this case, the charging facility 25 transmits information on the amount of charging power and information on the charging execution time to the home server 28.

  Moreover, in this embodiment, in addition to the home server 28 controlling the driving | operation of each equipment 21-25 based on a driving | operation priority as mentioned above, each equipment 21-25 based on a resident's action schedule and the actual condition of action. The operation is automatically controlled.

  For example, as the automatic control of the air conditioners 22-1 to 22-3, the resident's return time is predicted, and pre-air conditioning control is performed so that the operation of the air conditioner 22 is started before the return time. In this case, the operation of any of the air conditioning facilities 22-1 to 22-3 may be started depending on who is scheduled to return home. The prediction of the resident's return time may be performed by referring to schedule information set by the resident himself. Alternatively, the return time of the resident may be predicted using an electronic key possessed by the resident or a position detection function (GPS function) added to the mobile phone terminal 29. When the position detection function (GPS function) is given to the electric vehicle C, the return time of the resident may be predicted based on the traveling position of the electric vehicle C. In such a case, before the resident arrives at the house 10, the inside of the house 10 can be warmed or cooled.

  Further, as automatic control of the lighting equipment 21, the lighting equipment 21-4 of the entrance approach is turned on at a predetermined time. As a crime prevention measure, even if the resident is absent, at any given time, one of the indoor lighting facilities 21 can be turned on to perform a disguise effect as if the resident is at home. is there.

  Furthermore, as the automatic control of the charging facility 25, the use time of the electric vehicle C in the early morning or the work time using the electric vehicle C is predicted, and the vehicle charging is completed by the vehicle use time (work time). As shown, charging by the charging facility 25 is performed. For example, when going to work from the house 10 at 5:00 in the morning, charging by the charging facility 25 is automatically controlled so that the vehicle charging is completed by 5:00 in the morning.

  FIG. 3 is a flowchart showing the priority order setting process executed by the management server 31. This process is performed by the management server 31 triggered by the transmission of a setting request from the home server 28 of any home 10 or the mobile phone terminal 29 owned by the resident.

  In FIG. 3, in step S11, it is determined whether or not the driving priority data is unregistered, that is, whether or not this time is the first registration. If it is YES, it will progress to step S12 and will implement the first registration of driving priority data.

  At this time, in the management server 31, a plurality of setting patterns are determined in advance by combining each floor 10, each equipment data that can be installed in each house 10, and each assumed data of the family structure of each house 10. Basic data of driving priority is determined for each set pattern. Then, the management server 31 receives the actual floor plan data, the installation data of the equipment and the family composition data from the house 10 at the time of initial registration, and for each house 10 based on the respective data and the basic data of the driving priority. The driving priority data (default data) is determined. The driving priority data is stored in a folder of a storage device provided for each house 10.

  Moreover, when step S11 is NO, it progresses to step S13. In step S13, it is determined whether or not the setting change of the driving priority data is requested from the house 10. And if it is YES, it will progress to step S14 and will implement the setting change process of driving priority order data (default data). For example, when the house 10 requests to change the equipment control content based on the previously registered driving priority data (default data), the driving priority data is changed in response to the request. Is done. At this time, new driving priority data is registered by overwriting the previously registered driving priority data.

  In the home server 28, a procedure for changing the driving priority data is prepared as an operation menu, and the management server 31 changes the driving priority data (default data) as the resident performs the changing procedure. Is implemented.

  Next, the equipment control performed by the home server 28 will be described. FIG. 4 is a flowchart showing equipment control processing by the home server 28. This process is repeatedly performed by the home server 28 at a predetermined time period.

  In FIG. 4, in step S <b> 21, it is determined whether or not it is time to receive the driving priority data from the management server 31. For example, the home server 28 basically receives the driving priority data at a frequency of once a day. When the predetermined time (for example, 7:00 in the morning) is reached, the driving priority data is received from the management server 31. Receive. A configuration in which driving priority data is received at a frequency of a plurality of times per day or a configuration in which driving priority data is received at a frequency of once every several days may be employed.

  Further, when one driving priority data is defined as weekday data and one driving priority data is defined as weekend data, for example, the driving priority data for weekdays is set at 23:00 on Sunday. It is also possible to receive the driving priority data for Saturday and Sunday at 23:00 on Friday night.

  If step S21 is YES, the process proceeds to step S22. If NO, the process proceeds to step S24.

  In step S22, the management server 31 is instructed to transmit driving priority order data. In subsequent step S 23, the driving priority data (default data) received from the management server 31 is read and written in a predetermined storage area of the home server 28.

  Thereafter, in step S24, it is determined whether or not it is time to execute automatic control for any one of the facilities 21 to 25. And if step S24 is YES, it will progress to step S25 and will implement automatic control about applicable equipment.

  Here, for any one of the facilities 21 to 25, an automatic control schedule is determined in advance, and if the present time is the timing of the control execution, step S24 becomes YES. Then, the home server 28 outputs a control command for the equipment that is to be controlled this time. In this case, automatic control of any equipment is performed by a command signal from the home gateway device 27 to the communication units 21a to 25a of the equipments 21 to 25.

  For example, when the operation start time of the air conditioner 22 is determined in accordance with the resident's return time, the operation of the air conditioner 22 is started when the operation start time is reached. In addition, when the lighting time is determined for the entrance approach lighting equipment 21-4, the lighting equipment 21-4 is turned on when the lighting time is reached.

  Thereafter, in step S26, it is determined whether or not the driving priority is to be changed based on information on at least one of the usage status of each of the facilities 21 to 25 and the resident's behavior (corresponding to a change necessity determination unit). If it is determined that the driving priority order needs to be changed, the process proceeds to step S27 to execute a changing process for changing the driving priority order (corresponding to setting changing means), and then the present process is terminated. If it is determined that no change is necessary, the process is terminated as it is. In steps S26 and S27, a determination as to whether or not a change is necessary and a change process are performed as follows.

  -When a child is absent (when not returning home at the scheduled return time), it is determined that the driving priority needs to be changed, and the driving priority is lowered for the air conditioner 22-3 in the child room. For example, in the time zones A, C, and D of FIG. 2, the operation priority is changed so that the operation of the hot water supply facility 24 and the charging facility 25 is prioritized over the operation of the air conditioning facility 22-3 in the child room.

  -When the resident who mainly uses the electric vehicle C is absent (when the electric vehicle C is not used the next day), it is determined that the driving priority needs to be changed, and the driving priority of the charging facility 25 is lowered. For example, in the time zones F and G of FIG. 2, the driving priority is changed so that the driving of other devices is given priority over the driving of the charging facility 25 (vehicle charging).

  -Based on the past charging history of the charging facility 25, if the daily charging amount is small (below a predetermined amount), it is determined that the driving priority needs to be changed, and the charging facility 25 is operated. Lower priority. For example, in the time zones E to G of FIG. 2, the driving priority is changed so that the driving of other devices is given priority over the driving of the charging facility 25 (vehicle charging).

  In particular, with respect to each priority order of the hot water supply facility 24 and the charging facility 25, the change process may be performed as follows. That is, the hot water supply facility 24 and the charging facility 25 consume a large amount of power among the facility devices of the house 10. In the house 10 including both the facilities 24 and 25, both the facilities 24 and 25 are operated at the same time. As a result, there is a concern that the power supplied from the distribution board 11 increases at a stretch and power interruption occurs. Further, assuming simultaneous use of both of these facilities 24 and 25, a contract for large power is required as contract power (maximum demand power), resulting in inconvenience that the burden on the resident increases.

  Therefore, the mutual operation priority order is determined for both the facilities 24 and 25 (see, for example, FIG. 2). In such a configuration, when the driving priority order is changed based on the use schedule of the electric vehicle C, the priority order of the charging equipment 25 and the priority order of the hot water supply equipment 24 are interchanged. For example, if the hot water supply facility 24 has a lower priority and the charging facility 25 has a higher priority, if there is no plan to use the electric vehicle C the next day, the mutual operation priority of the hot water supply facility 24 and the charging facility 25 is reversed. The hot water supply facility 24 is given priority and the charging facility 25 is given priority.

  In addition, when the change process of driving priority is implemented, you may make it transmit the content of a change from the home server 28 to the management server 31 side whenever it changes. In this case, the management server 31 stores the change history or registers the changed driving priority data as new default data.

  As described above, the home server 28 implements equipment device control and operation priority change. The home server 28 performs the control process shown in FIG. 5 at a predetermined time period in parallel with the process of FIG. In FIG. 5, for example, the processing is started with a period of several seconds to several tens of seconds, and thus, constant power monitoring is performed.

  In FIG. 5, in step S <b> 31, the present total electric power P used in the house 10 is calculated (corresponding to a calculation means). The total power P is calculated based on the power monitoring result by the power monitoring device 16. Thereafter, in step S32, it is determined whether or not the current total power consumption P is equal to or greater than a predetermined allowable value K. The allowable value K is a power upper limit value determined based on the contract power for each house 10 and is, for example, “contract power-α”. If the total power consumption P ≧ allowable value K, the process proceeds to step S33. If the total power consumption P <allowable value K, the process is terminated.

  In step S33, using the operation priority data (default data) or the changed operation priority data set and changed in step S27 in FIG. Is stopped (corresponding to the limiting means). That is, the operation priority of each facility 21 to 25 in the time zone corresponding to the current time is read from the operation priority data, and the operation of any equipment is stopped based on the priority.

  In addition, when the operation of facility equipment is forcibly stopped based on the operation priority, the facility equipment that has been forcibly stopped is stored, and the operation is automatically restarted when there is a margin in power consumption. Good. For example, when “allowable value K−total power use P” becomes equal to or greater than a predetermined value, the operation of the equipment that has been forcibly stopped before that is restarted.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  When all the used electric power P reaches the allowable value K (predetermined electric power upper limit value) in the house 10, the operation of any of the facilities is limited based on the predetermined operation priority order for each of the facilities 21 to 25. I did it. As a result, it is possible to regulate the total power consumption P so as not to exceed the allowable value K, and it is possible to suppress inconveniences such as unintentional breaker breakage due to excessive power supply.

  In addition, it is determined whether or not the driving priority needs to be changed in accordance with the usage status of each of the facilities 21 to 25 and the behavior of the resident. When it is determined that the driving priority is required, the setting change is performed for the driving priority. . Thereby, in the actual use of each equipment 21-25 in the house 10, even if the use situation and usage needs of each equipment 21-25 change, for example, every day, the convenience by the resident is improved while reflecting it. Is possible. Thereby, it becomes possible to control operation of each equipment 21-25 suitably.

  Priorities of the respective facilities 21 to 25 are determined for a plurality of time zones in a day, and the operation of any of the facilities is restricted based on the priorities for the respective time zones. In addition, settings were changed individually for priorities for each time zone. Thereby, the operation control of each equipment 21-25 can be implemented suitably, considering that the time zone of use is different about each equipment 21-25.

  Based on the determination result of who is at home among the residents in the house 10 (that is, the determination result of who is going out and who has returned home), it is determined whether or not the driving priority needs to be changed. When it is determined, the setting is changed for the driving priority. In this case, in consideration of the fact that which equipment is actually used (operated) depends on who is resident at home, it is in line with the actual situation of each resident's house. Thus, the operation of each of the facilities 21 to 25 can be suitably controlled.

  Based on the result of determining the use schedule of the electric vehicle C, it is determined whether or not it is necessary to change the driving priority, and when it is determined that the change is necessary, the setting change is performed for the driving priority. In this case, it is possible to suitably control the operation of each of the facilities 21 to 25 while considering that the power margin in the house 10 varies greatly depending on whether or not the vehicle charging by the charging facility 25 is performed.

  In the case of changing the driving priority order based on the use schedule of the electric vehicle C, the priority order of the charging facility 25 and the hot water supply facility 24 is interchanged. As a result, it is possible to meet the needs of each facility use while suppressing the inconvenience that the total power consumption P exceeds the contract power due to the simultaneous use of the hot water supply facility 24 and the charging facility 25 or the contract power is forced to increase in power. Accordingly, the operation of each of the facilities 21 to 25 can be suitably controlled.

  Driving priority order data is registered as default data in the management server 31, and the home server 28 receives driving priority order data (default data) from the management server 31 as necessary. It was set as the structure which implements control of driving | operation of ~ 25. In such a configuration, since driving priority order data (default data) is managed on the management server 31 side, a uniform setting change is performed for a plurality of houses 10 instead of a setting change due to individual circumstances for each house 10. In other words, for example, when the driving priority data (default data) is changed for each season or for each region, the change can be performed simultaneously. Therefore, it is considered that it is advantageous in terms of management.

  For example, when the management server 31 changes the driving priority data in order to increase the driving priority of the air conditioning equipment 22 during a predetermined period in summer, uniform setting changes can be made for the plurality of houses 10. In addition, when a situation occurs in which the power supply from the power company to each house 10 is restricted in order to suppress an increase in power demand or the like, the management server 31 enables uniform setting changes for the plurality of houses 10.

  The management server 31 can communicate with a mobile phone terminal 29 carried by a resident. Then, in response to a request from the mobile phone terminal 29, the management server 31 notifies the housing 10 side of the operation control content of each facility 21 to 25, and information on the operation state of each facility 21 to 25 The mobile phone terminal 29 is configured to receive the received information from the 10 side and notify the mobile phone terminal 29 of the received information. According to this configuration, it is possible to transmit information from the mobile phone terminal 29 to the management server 31 and vice versa to transmit information from the management server 31 to the mobile phone terminal 29. Therefore, even if the resident has gone out, the resident can control the operation of each facility 21 to 25 and monitor the operation state of each facility 21 to 25 at an arbitrary timing.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  -In the night time zone (night time from 23 o'clock to 7 o'clock in the morning) when cheap night electricity is supplied, the operation priority of the hot water supply equipment 24 and the charging equipment 25 is set to the operation priority of the hot water supply equipment 24 throughout the time zone. Is set at the upper level, and the operation priority of the charging facility 25 is set at the lower level. And about the driving | operation priority of both, it is good also as a structure which implements mutual replacement | exchange based on the determination result of necessity of change each time.

  For example, the driving priority order is changed according to the predicted travel distance of the next day for the electric vehicle. In this case, if the predicted travel distance of the next day is greater than the predetermined distance, it is determined that a change is necessary, and the operation priority of the charging facility 25 is changed to the higher rank and the operation priority order of the hot water supply facility 24 is changed to the lower rank. Alternatively, the driving priority order is changed according to the use start time for the electric vehicle. In this case, if the use start time is earlier than usual, it is determined that the change is necessary, and the operation priority of the charging facility 25 is changed to the higher rank, and the operation priority of the hot water supply facility 24 is changed to the lower rank.

  Contrary to the above, in the night time zone (from 23:00 to 7:00 in the morning), the hot water supply equipment 24 may be given priority and the charging equipment 25 may be given higher ranking throughout the time zone. And about the driving | running priority of both of them, mutual replacement | exchange is implemented based on the determination result of necessity of change each time.

  -About each installation apparatus installed in the house 10, the kind and installation number are arbitrary. For example, the hot water supply facility 24 and the charging facility 25 may have only one of the two facilities.

  -In above-mentioned embodiment, when all the electric power P of the house 10 exceeded the allowable value K, it was set as the structure which forcibly stops the driving | operation of the low operation priority among each equipment 21-25, but this It is good also as a structure which reduces an electric power consumption by reducing an operation load about the equipment with a low driving | running priority among each equipment 21-25, when the total electric power P of the house 10 exceeds the allowable value K similarly. For example, when the operation priority of the air conditioner 22 is low, the operation of the air conditioner 22 is not stopped but the heating temperature of the air conditioner is lowered (or the cooling temperature is raised), or the air conditioning air volume is reduced. To do. Alternatively, when the driving priority of the charging facility 25 is low, the charging of the electric vehicle C is reduced (the charging amount per hour is reduced) instead of stopping the vehicle charging.

  -It is good also as a structure which provides the natural energy power generation apparatus which generate | occur | produces with natural energy in the house 10, and supplies the electric power generated of the natural energy power generation apparatus to each installation 21-25 or the household appliances 26. FIG. As a natural energy power generation device, a solar power generation device that performs solar power generation, a wind power generation device that performs wind power generation, and the like are conceivable. In the house 10, natural energy generated power is supplied to each of the facilities 21 to 25 and the home appliance 26 in addition to the commercial power by the distribution board 11 as a power feeding unit. In this case, the power upper limit value may be determined by the sum of the contract power (maximum demand power) for commercial power and the natural energy generated power each time.

  In the above embodiment, the home server 28 is provided for each house 10, and the operation of each facility 21 to 25 is controlled by the home server 28. However, the function of the home server 28 described so far is changed. It is good also as a structure which controls the driving | operation of each installation 21-25 by the management server 31 by having in the management server 31. FIG. Further, in this case, the management server 31 controls the operation of each of the facilities 21 to 25 based on the operation priority order, so that the management server 31 constitutes a limiting unit, a change necessity determination unit, and a setting change unit. May be.

  In the above embodiment, the communication units 21a to 25a are provided in the facilities 21 to 25, and the communication units 21a to 25a and the home gateway device 27 perform wireless communication. However, the communication method is arbitrary. In addition, a configuration in which the facilities 21 to 25 and the home gateway device 27 are connected by a LAN cable to perform communication in the house 10 may be used.
