Description

  Embodiments described herein relate generally to an electronic device and a device system applied to, for example, a digital television.

  In recent years, the importance of efficient power use and peak cut / shift of power use has been highlighted due to the power shortage after the earthquake. In order to achieve peak cut / shift of power usage, traditionally demanding power savings from customers has been requested, and the demand response (DR (Demand Response)) that realizes power savings by customer behavior in response to these requests is effective. Sex is being studied.

  However, in order to realize DR according to the conventional concept, a considerable initial cost is required to install a device that realizes “visualization” of the amount of power used (power consumption) and a device that displays a request for DR. It was necessary and had a problem that the initial cost could not be recovered in a realistic period with the consideration obtained by DR. Furthermore, in order to automate or semi-automate DR, it is necessary to additionally install a device for remotely controlling a device such as an air conditioner, which requires further cost.

  With regard to equipment that realizes “visualization” of the amount of power used, the above-described visualization may be realized at low cost with the spread of smart meters in the near future. At present, focusing on reducing the cost of equipment that displays DR requests, while expanding the power consumption capturing function from smart meters, to achieve “visualization” of power consumption. By doing so, it is becoming a situation where the conventional problems can be overcome.

  On the other hand, terrestrial digitalization of television broadcasting has been completed, and digital television has already entered the stage of full-scale diffusion in each household. Digital TV has characteristics as an interactive communication tool by connecting to the Internet. In addition, since a digital TV is often installed in a living room or dining room where power consumption is most concentrated in the home, it has suitability as a device for displaying a request for DR.

  As described above, it is expected that DR in individual home units will be developed by combining the function of measuring power consumption using a smart meter and the function of displaying a request for DR using a digital television.

JP 2009-273359 A

  By the way, the electric power company grasps whether or not the consumer has performed the power saving action due to the request of the DR to each customer, evaluates the degree of cooperation with the DR, and determines the degree of cooperation. Based on this, we are seeking incentives such as price discounts for customers.

  However, smart meters are not widely used for each customer at present due to cost problems, and at present, the amount of power used by each customer cannot be accurately grasped in real time. The progress of DR requires the above-described incentive to be obtained with high accuracy, but the incentive cannot be accurately determined unless the amount of power used by each consumer can be accurately grasped. Thus, at present, it is not possible to contribute to the peak shift of power without installing expensive equipment.

  The problem to be solved by the present invention is to provide an electronic device and a device system that can contribute to the peak shift of power without installing a high-cost device.

  According to the embodiment, the electronic device receives from the external device information for requesting power saving to a consumer who uses power, and display control for displaying on the display device the information received by the receiving unit. And means for discriminating whether or not to accept power saving indicated by the consumer for the information displayed on the display device. This electronic device has a detection means for detecting a physical quantity that is influenced by the use of electric power by the consumer, and information indicating that the acceptance has been made when the acceptance means is determined by the determination means, Transmission means for transmitting the detection results by the detection means before and after the acceptance to the external device.

The DR screen may be displayed in other parts.

  On this DR screen, a button for selecting whether or not the customer accepts the DR is displayed. The consumer can select whether to accept or reject the DR request by performing a predetermined operation on the remote controller for the digital television 10 with built-in IHD function.

  The storage device 21 is a storage medium such as a nonvolatile memory, for example, and stores programs for processing operations of the control unit 11, the infrared communication unit 14, the home gateway device (HGW) 17, and the display control unit 19. In addition, the storage device 21 has a storage area for storing detection results from the temperature sensor 12 and the illuminance sensor 13.

FIG. 2 is a diagram illustrating a functional configuration example of the home gateway device of the digital television with a built-in IHD function according to the embodiment.
As shown in FIG. 2, the home gateway device 17 includes a communication interface 17a, a DR signal receiving unit 17b, a temperature acquiring unit 17c, an illuminance acquiring unit 17d, an evidence data transmitting unit 17e, a response data processing unit 17f, and a device information acquiring unit 17g. , An energy saving operation activation command unit 17h and a response sound acquisition unit 17i. Among these, the device information acquisition unit 17g, the energy saving operation activation command unit 17h, and the response sound acquisition unit 17i are provided in other embodiments, and are not provided in the first embodiment.

The communication interface 17a performs communication with the DR server 40.
The DR signal receiving unit 17b receives the DR signal transmitted from the DR server 40 via the communication interface 17a.
The temperature acquisition unit 17 c acquires a detection result by the temperature sensor 12.
The illuminance acquisition unit 17d acquires the detection result by the illuminance sensor 13.

  The evidence data transmission unit 17e returns the acquisition result by the temperature acquisition unit 17c before and after the DR request and the acquisition result by the illuminance acquisition unit 17d before and after the DR request to the DR server 40 via the communication interface 17a. These acquisition results are evidence data of power saving behavior accompanying acceptance of DR by a consumer.

The response data processing unit 17f returns data indicating whether or not the DR is accepted by the consumer to the DR server 40 via the communication interface 17a as response data.
When the consumer accepts the DR requested by the DR signal from the DR server 40, the device information acquisition unit 17g acquires information on the target device for power saving from the storage device 21.

  The energy saving operation activation command unit 17h is configured to shift the power control mode of the digital television 10 with built-in IHD function to the energy saving mode when the customer accepts the DR requested by the DR signal from the DR server 40. The activation command is output to the power supply control unit 71.

FIG. 3 is a block diagram illustrating a configuration example of the DR server of the device system for performing a power demand response in the first embodiment.
As illustrated in FIG. 3, the DR server 40 includes a communication unit 41, an evaluation unit 42, an incentive calculation unit 43, a storage device 44, and a base load calculation unit 45. The base load calculation unit 45 is provided in a sixth embodiment to be described later, and is not provided in the other embodiments. The communication unit 41 performs communication with the home gateway device 17 of the digital television 10 with a built-in IHD function. The communication unit 41 transmits a DR signal to the home gateway device 17 in the consumer-equipped digital TV 10 with the IHD function at a predetermined timing for requesting the DR to the customer in order to request the DR to the customer.

Based on the response data and the evidence data from the home gateway device 17, the evaluation unit 42 evaluates the degree of cooperation with DR by the consumer who is the source of these data.
For example, the ratio of acceptance by the customer is high with respect to the number of DR requests to the customer, or the room temperature and illuminance after the DR request indicated by the evidence data are significantly higher than the room temperature and illuminance before the request. If it is low, the degree of cooperation is high.

  The incentive calculation unit 43 calculates an incentive for the customer who requested the DR based on the evaluation result of the degree of cooperation by the evaluation unit 42. Incentives include, for example, discounting electricity charges, or giving points that can be used for electricity charges and other payments. If the degree of cooperation described above is high, the calculated incentive is high.

Hereinafter, the operation of the device system when DR is requested by a consumer will be described. FIG. 4 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the first embodiment. The program according to the flowchart is built in the control unit 11.
The communication unit 41 of the DR server 40 transmits a DR signal to the home gateway device 17 in the digital television 10 with a built-in IHD function via the network in order to request DR from the customer.

  When receiving the DR signal from the DR server 40 via the communication interface 17a (step S1), the DR signal receiving unit 17b of the home gateway device 17 outputs the DR signal to the temperature acquisition unit 17c and the illuminance acquisition unit 17d. Further, the DR signal receiving unit 17 b outputs the DR signal to the display control unit 19 via the control unit 11.

When receiving the DR signal, the temperature acquisition unit 17c of the home gateway device 17 acquires the room temperature detected by the temperature sensor 12. Moreover, the illuminance acquisition unit 17d of the home gateway device 17 acquires the illuminance detected by the illuminance sensor 13 when the DR signal is input.
The evidence data transmission unit 17e stores these acquisition results in the storage device 21 as evidence data before acceptance of the DR in association with the current date and time measured by the built-in clock (step S2).

  When the digital video 10 with built-in IHD function is displaying a television broadcast on the display device 20 (YES in step S3), the display control unit 19 superimposes it on the screen of the television broadcast being displayed. The DR screen is displayed on the display device 20 (step S4). Thereby, it is possible to semi-forcibly notify the customer who is viewing the digital television 10 with built-in IHD function that the DR is requested.

  At this time, the control unit 11 may sound a chime sound from a speaker (not shown) of the digital TV 10 with a built-in IHD function. When the TV broadcast recording function by the digital TV 10 with built-in IHD function is operating, the DR screen displayed superimposed on the TV broadcast screen is not recorded.

  When the power supply of the display device 20 of the digital television 10 with built-in IHD function is in a dormant state and no television broadcast is displayed on the display device 20, the control unit 11 turns on the power of the display device 20. The display control unit 19 displays a DR screen on the display screen of the display device 20. At this time, the control unit 11 sounds a chime sound from the speaker of the digital television 10 with a built-in IHD function (step S5). By making the chime sound like this, even if the consumer is not using the digital television 10 with built-in IHD function, it is possible to easily know that the DR is requested if the customer is in the vicinity.

FIG. 5 is a diagram showing an example of a display screen of the digital television with a built-in IHD function in the first embodiment.
As shown in FIG. 5, the DR screen displays a message for requesting DR to the customer, and the customer accepts ("yes") or rejects the request for DR (" A button for selecting “no”) is displayed. After S4 or S5, the consumer selects whether to accept or reject the DR request by performing a predetermined operation on the remote controller for the digital television 10 with built-in IHD function.

  If the customer has selected on the DR screen to reject the DR request by performing a predetermined operation on the remote control for the digital television 10 with built-in IHD function (NO in S6), this selection is indicated. The selection signal is transmitted to the home gateway device 17 via the infrared communication unit 14 and the control unit 11.

  When the response data processing unit 17f of the home gateway device 17 receives the selection signal, the DR server 40 sends response data (rejection) indicating that the customer rejects the DR request via the communication interface 17a and the communication network. (Step S7).

  On the other hand, if the customer has selected on the DR screen to accept the DR request by performing a predetermined operation on the remote control for the digital TV 10 with built-in IHD function (YES in S6), this selection is made. Is transmitted to the home gateway device 17 via the infrared communication unit 14 and the control unit 11.

  When the response data processing unit 17f of the home gateway device 17 receives the selection signal, the response data (acceptance) indicating that the consumer accepts the DR request is received via the communication interface 17a and the communication network. (Step S8). The customer who has accepted the request for DR responds to the power saving requested by the DR by performing energy saving actions such as turning off the lighting of the room or operating home appliances such as the air conditioners 30 and 31. The operation of the air conditioners 30 and 31 for power saving includes changing the set temperature and turning off the power.

  The energy saving action executed in this way appears as a change in room illuminance or a change in room temperature. These changes can be grasped as evidence that the consumer has performed an energy saving action by the temperature sensor 12 and the illuminance sensor 13 of the digital television 10 with built-in IHD function.

  When the response data (acceptance) is input, the temperature acquisition unit 17c acquires the temperature detected by the temperature sensor 12 after a lapse of a certain time from this input as the room temperature after the acceptance of the DR. In addition, when the response data (acceptance) is input, the illuminance acquisition unit 17d acquires the illuminance detected by the illuminance sensor 13 after a predetermined time has elapsed from this input as the illuminance after acceptance of the DR. The reason why the time is provided between the input of the response data (acceptance) and the acquisition of the room temperature and the illuminance is because it is necessary to consider the time from the acceptance of the DR to the actual power saving action. It is.

  The evidence data transmission unit 17e stores these acquisition results in the storage device 21 as evidence data after acceptance of the DR in association with the current date and time measured by the internal clock. The evidence data transmitting unit 17e reads the evidence data before acceptance of the DR stored in the storage device 21 in S2, and provides the evidence data before and after acceptance of the DR via the communication interface 17a and the communication network. 40. Further, the response data processing unit 17f transmits response data (acceptance) to the DR server 40 via the communication interface 17a and the communication network (step S9).

  When the communication unit 41 of the DR server 40 receives response data (rejection) after S7, or when the communication unit 41 receives evidence data before and after acceptance of DR and response data (acceptance) after S9, the evaluation unit 42 stores the received data in the storage device 44 in association with predetermined identification information of the consumer of the transmission source.

The evidence data before and after the acceptance of the DR from the customer side and the response data are stored and accumulated in the storage device 44 of the DR server 40 every time the DR is requested.
And the evaluation part 42 reads the evidence data before and after acceptance of DR within the fixed period, and response data which were accumulate | stored in the memory | storage device 44 about the same consumer at predetermined timing. Based on the read data, the evaluation unit 42 evaluates the degree of cooperation of the customer with respect to the DR request to the corresponding customer within the certain period (step S10).

  The evaluation unit 42 refers to the current date and time associated with the evidence data before and after the acceptance of the DR in evaluating the cooperation degree of the customer, and the room temperature before the acceptance and the room temperature after the acceptance indicated by the evidence data before and after the acceptance of the DR. And the difference between the illuminance before acceptance and the illuminance after acceptance indicated by the evidence data before and after the acceptance of DR. The difference between the room temperature before acceptance indicated by the evidence data before and after acceptance of the DR and the room temperature after acceptance is large, or the difference between the illuminance before acceptance and the illumination after acceptance indicated by the evidence data before and after acceptance of the DR is large. As a result, the degree of cooperation increases.

The difference between the room temperature before acceptance indicated by the evidence data before and after acceptance of the DR and the room temperature after acceptance, and the difference between the illuminance before acceptance indicated by the evidence data before and after acceptance of the DR and the illuminance after acceptance are as follows: It may be obtained in advance by the home gateway device 17 and the evaluation unit 42 of the DR server 40 may obtain information indicating only this difference as evidence data.
The incentive calculation unit 43 calculates an incentive for the consumer based on the evaluation result by the evaluation unit 42 (step S11).

  As described above, the device system according to the first embodiment has a configuration in which an IHD function is mounted on a consumer's digital television and a DR request is semi-forcibly notified to the consumer using this function. . Furthermore, in this embodiment, based on the room temperature before and after acceptance of DR by the customer and the illuminance in the room, the degree of cooperation with the customer by DR is evaluated, and based on this evaluation result, the incentive to the customer is given. It was set as the structure to calculate. With such a configuration, the incentive based on the DR requested by the consumer can be calculated without installing an IHD dedicated device or smart meter on the consumer side. The system can be realized at low cost.

  From the customer's viewpoint, if there is a digital TV that the customer uses in daily life, the DR request can be easily known through the screen of this digital TV, so the effect of transmitting the DR request to the customer Is expensive. For this reason, the energy saving effect by DR can be made high.

  Further, if the consumer operates the television remote control according to the DR screen, the customer can make a selection for accepting the DR request. Thus, since it is not necessary to add a dedicated device for responding to the DR, there is no problem in the installation space on the customer side, and the cost can be reduced.

(Second Embodiment)
Next, a second embodiment will be described. In addition, description of the part same as what was shown in 1st Embodiment among the structures of the apparatus system in each following embodiment is abbreviate | omitted. In the second embodiment, a function for automatically performing control for energy saving in response to a request for DR is added to the first embodiment.

FIG. 6 is a block diagram illustrating a second configuration example of a device system for performing a power demand response in the embodiment.
The device system shown in FIG. 6 includes an IHD function built-in digital television 10 and a DR server 40. The digital television 10 with built-in IHD function shown in FIG. 6 includes a control unit 11, a temperature sensor 12, an illuminance sensor 13, an infrared communication unit 14, a microphone 15, a home gateway device 17, a tuner 18, a display control unit 19, a display device 20, and storage. A device 21 and a learning remote control unit 51 are included.

  Among these, the microphone 15 is provided in other embodiments, and is not provided in the second embodiment. Of the components in the digital television 10 with built-in IHD function shown in FIG. 6, the components other than the microphone 15 are provided in the second embodiment.

  The learning remote controller 51 learns the infrared operation signal of the remote controller of the device to be controlled for power saving when the customer accepts the DR request, and stores the learning content and the identification information of the device in the internal memory. . Control for power saving means control for energy saving setting. The devices to be controlled may be air conditioners 30 and 31 or lighting that can be turned on and off by remote control operation.

  Further, the home gateway device 17 in the second embodiment includes a communication interface 17a, a DR signal receiving unit 17b, a temperature acquiring unit 17c, an illuminance acquiring unit 17d, an evidence data transmitting unit 17e, a response, among the configurations shown in FIG. It has a data processing unit 17f, a device information acquisition unit 17g, and an energy saving operation activation command unit 17h. That is, in the second embodiment, the home gateway device 17 further includes a device information acquisition unit 17g and an energy saving operation activation command unit 17h in addition to the configuration of the first embodiment.

Hereinafter, an operation when DR is requested by a customer will be described.
FIG. 7 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the second embodiment.
First, the same operation as S1 to S5 described in the first embodiment is performed.
After S4 or S5, the device information acquisition unit 17g of the home gateway device 17 reads the identification information of the device to be controlled for power saving according to the DR stored in the internal memory of the learning remote control unit 51. The device information acquisition unit 17 g outputs this identification information to the display control unit 19. The display control unit 19 causes the display device 20 to display a message for notifying the device icons I1 and I2 corresponding to the identification information and a notice of automatic execution of power saving control for these devices for a certain period of time ( Step S21). Thereby, the consumer can easily grasp the advance notice of the automatic execution of the control for power saving and the type of the device to be controlled for power saving.

FIG. 8 is a diagram illustrating an example of a notification screen for automatic execution of control for power saving.
As shown in FIG. 8, an automatic execution stop button for stopping the automatic execution of control for power saving is displayed on the notification screen for a certain period of time. In the example shown in FIG. 8, the automatic execution stop button is displayed as “stop”. If the consumer performs a predetermined operation on the remote controller for the digital television 10 with built-in IHD function within this fixed time and the automatic execution stop button is selected (YES in step S22), the selection signal is sent to the infrared communication unit 14 The response data processing unit 17 f of the home gateway device 17 is output via the control unit 11.

  When receiving the selection signal, the response data processing unit 17f returns response data (rejection) indicating that the customer rejects the DR request to the DR server 40 via the communication interface 17a and the communication network (Step S1). S23).

  On the other hand, if the above-described fixed time has elapsed without selecting the automatic execution stop button (YES in step S24), the energy saving operation activation command unit 17h considers that the request for DR has been accepted by the customer. Then, the energy saving operation activation command unit 17h instructs the learning remote control unit 51 to activate the registered energy saving operation of the device to be controlled for power saving (step S25).

  Thus, in this embodiment, when a consumer does not refuse a request for DR, an energy saving operation for power saving can be automatically activated. Thus, when the consumer accepts the DR request, the energy-saving operation of the device to be controlled for power saving can be activated even if the consumer does not particularly perform an operation on the screen.

  The learning remote controller 51 that has received the command to start the energy saving operation, for example, changes the set temperature of the air conditioners 30 and 31, turns off the power of the air conditioners 30 and 31, and turns off the indoor lighting. Is transmitted from the infrared communication unit 14 to each device (step S26). As a result, the energy saving operation of each device on the consumer side is activated (step S27).

  And the temperature acquisition part 17c acquires the temperature detected by the temperature sensor 12 as room temperature after acceptance of DR. The illuminance acquisition unit 17d acquires the illuminance detected by the illuminance sensor 13 as the illuminance after acceptance of the DR.

  The evidence data transmission unit 17e stores these acquisition results in the storage device 21 as evidence data after acceptance of the DR in association with the current date and time measured by the internal clock. The evidence data transmission unit 17e reads the evidence data before acceptance of the DR stored in the storage device 21 in S2, and provides the evidence data before and after acceptance of the DR via the communication interface 17a and the communication network. Send to. Further, the response data processing unit 17f transmits the response data (acceptance) to the DR server 40 via the communication interface 17a and the communication network (step S28).

  If the communication unit 41 of the DR server 40 receives response data (rejection) after S23, or if the communication unit 41 receives evidence data before and after acceptance of DR and response data (acceptance) after S28, the first In the embodiment described above, the evaluation of the cooperation degree that is S10 and the calculation of the incentive that is S11 are performed.

  As described above, in the device system according to the second embodiment, in addition to the features described in the first embodiment, the energy saving operation for the DR request to the consumer is automatically performed without requiring any operation by the consumer. Can be done. In addition, since the control target device for power saving according to the DR is controlled using the function of the learning remote control of the digital television that is used in daily life, the energy saving operation for the DR request to the consumer is performed. The cost for performing automatically can be reduced.

  In the above description, the change in temperature and the change in illuminance before and after the acceptance of the DR are regarded as evidence data of the power saving action accompanying the acceptance of the DR request. However, when a smart meter is installed in the consumer's home in the future, the change in power consumption before and after acceptance of the DR is measured by the smart meter, and this measurement result is used to save power when the DR is accepted. It may be at least part of the evidence data indicating the action. The same applies to the following embodiments.

(Third embodiment)
Next, a third embodiment will be described. The third embodiment is a mode in which a function for reliably performing an operation for energy saving in response to a DR request is added to the second embodiment.
In the present embodiment, the digital television 10 with built-in IHD function includes a control unit 11, a temperature sensor 12, an illuminance sensor 13, an infrared communication unit 14, a microphone 15, a home gateway device (HGW) 17, among the configurations shown in FIG. A tuner 18, a display control unit 19, a display device 20, and a storage device 21 are included.

The microphone 15 detects a response sound generated by the air conditioners 30 and 31 when the learning remote controller 51 operates the air conditioners 30 and 31.
In the third embodiment, as shown in FIG. 2, the home gateway device 17 includes a communication interface 17a, a DR signal receiving unit 17b, a temperature acquiring unit 17c, an illuminance acquiring unit 17d, an evidence data transmitting unit 17e, a response It has a data processing unit 17f, a device information acquisition unit 17g, an energy saving operation activation command unit 17h, and a response sound acquisition unit 17i.
That is, in the third embodiment, the home gateway device 17 further includes a response sound acquisition unit 17i in addition to the configuration of the second embodiment.

  The response sound acquisition unit 17i of the home gateway device 17 acquires the remote control response sound output from the device via the microphone 15 in accordance with the control of the power saving target device in response to the DR signal request from the DR server 40. To do. In the present embodiment, it is assumed that the devices that emit remote control sound are the air conditioners 30 and 31.

  The response sound acquisition unit 17i stores in advance the reference information of the remote control response sound of the air conditioners 30 and 31 that are power saving target devices in the internal memory. The remote control response sound information is classified for each type of operation. This information is information indicating a sound such as “beep” or “beep”, for example. This information is used to determine whether or not correct control has been performed when the power-saving target device is controlled for energy saving setting by the learning remote controller 51.

Hereinafter, an operation when DR is requested by a customer will be described.
FIG. 9 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the third embodiment.
First, the same operations as S1 to S5 and S21 to S27 described in the second embodiment are performed. After S27, the response sound acquisition unit 17i of the home gateway device 17 recognizes the response sound emitted from the corresponding device via the microphone 15 (step S31).

  The response sound acquisition unit 17i includes information on the response sound corresponding to the operation for power saving instructed by the energy saving operation activation command unit 17h among the recognized response sound and the remote control response sound reference information stored in the internal memory. Are collated (step S32).

  As described above, the reason why it is determined whether or not the correct control for energy saving is performed is, for example, the remote control signal for turning on the power and the remote control signal for turning off the power, such as the power on / off control of the air conditioners 30 and 31. This is because when the control is based on the so-called toggle operation, the operation of the device is different from the operation for energy saving depending on the current state of the power supply of the device.

  In S32, the response sound acquisition unit 17i reads the reference information of the response sound corresponding to the power-off when the control for power saving is the power-off of the air conditioners 30 and 31, from the internal memory. And the response sound recognized in S31.

  If the response sound recognized in S31 does not match the reference information of the remote control response sound to be verified (NO in step S32), the response sound acquisition unit 17i determines that an operation different from the operation for energy saving has been performed. The determination result is output to the learning remote controller 51, and the process returns to S26.

  In this returned S26, when the learning remote controller 51 inputs the determination result from the response sound acquisition unit 17i, the learning remote controller 51 causes the device that has performed the different operations described above to perform the operation for energy saving. An infrared remote control signal is transmitted from the infrared communication unit 14. Thus, correct control for energy saving can be performed by operating again a device that has been operated differently from the operation for energy saving.

Moreover, the response sound acquisition part 17i determines with the correct control for energy saving having been made, when a coincidence corresponds with the reference information of the recognized response sound and the remote control response sound to be verified (YES in step S32).
Then, transmission of evidence data and response data (acceptance) before and after DR acceptance, which is S28 described in the second embodiment, is performed.

  When the communication unit 41 of the DR server 40 receives response data (rejection) after S23, or after the communication unit 41 receives evidence data before and after acceptance of DR and response data (acceptance) after S28, the second In the embodiment described above, the evaluation of the cooperation degree that is S10 and the calculation of the incentive that is S11 are performed.

  As described above, in the device system according to the third embodiment, in addition to the features described in the second embodiment, the remote control operation for the power saving target device according to the DR request is different from the operation for power saving. When it was an operation, the correct operation for power saving was performed through the remote control operation again. By doing in this way, the operation | movement for power saving with respect to the request | requirement of DR can be performed reliably.

(Fourth embodiment)
Next, a fourth embodiment will be described. The fourth embodiment is a form in which a function for performing energy saving setting of the digital television 10 with built-in IHD function accompanying a DR request is added to the first embodiment.

  The energy saving setting of the digital television with built-in IHD function 10 is, for example, turning off the display by the display device 20. By performing such setting, the power consumption of the digital television 10 with built-in IHD function itself can be reduced, and the power saving effect by DR can be enhanced.

  The digital television 10 with built-in IHD function in the present embodiment includes a control unit 11, a temperature sensor 12, an illuminance sensor 13, an infrared communication unit 14, a home gateway device (HGW) 17, a tuner 18 and a display, among the configurations shown in FIG. A control unit 19, a display device 20, a storage device 21, and a power supply control unit 71 are included. In the configuration illustrated in FIG. 1, the DR signal transmission unit 91 and the response information reception unit 92 are provided in other embodiments, and are not provided in the fourth embodiment.

  When the consumer accepts the DR requested by the DR signal from the DR server 40, the power control unit 71 shifts the power control mode of the digital television 10 with built-in IHD function to the energy saving mode. In this energy saving mode, the display by the display device 20 is turned off. At this time, the control unit 11 may activate the television broadcast recording mode and store the television broadcast currently displayed on the display device 20 in the storage device 21.

  Among major home appliances, digital TV uses the second highest power after air conditioners. Therefore, in the present embodiment, in response to a request for DR, the power consumption of the digital television 10 with a built-in IHD function is suppressed to enhance the DR effect.

Hereinafter, an operation when DR is requested by a customer will be described.
FIG. 10 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the fourth embodiment.
FIG. 11 is a diagram illustrating an example of a notification screen for switching the power control mode for power saving.
First, the same operation as S1 to S8 described in the first embodiment is performed.
After S8, the display control unit 19 causes the display device 20 to display a notification screen when the power control mode of the digital television 10 with built-in IHD function is switched to the energy saving mode, as shown in FIG. The reason for displaying the power control mode switching notification screen for power saving on the display device 20 in this way is to inform the customer in advance that the display of the display device 20 will be turned off for power saving, and misidentify it as a failure. This is to prevent it from being done.

  After this fixed time has elapsed, the power supply control unit 71 shifts the power supply control mode of the digital television 10 with built-in IHD function to the energy saving mode, and turns off the display by the display device 20 (step S41). As a result, the power used by the digital television 10 with built-in IHD function can be suppressed.

Next, the same operation as S9 described in the first embodiment is performed. Thereby, the evidence data and the response data (acceptance) before and after the acceptance of the DR are transmitted to the DR server 40.
Then, the evidence data transmission unit 17e reads information on the amount of power consumption reduction of the digital television 10 with a built-in IHD function from the internal memory accompanying the transition of the power control mode to the energy saving mode, and uses this information as a communication interface 17a, a communication The data is transmitted to the DR server 40 via the network (step S42). The amount of power consumption reduction is determined based on the specifications of the digital television 10 with a built-in IHD function.

After S7, the communication unit 41 of the DR server 40 receives the response data (rejection), or after S42, the communication unit 41 confirms the evidence data before and after the acceptance of the DR, the response data (acceptance), and the power consumption reduction amount. When the information is received, the evaluation unit 42 stores the received data in the storage device 44 in association with the predetermined identification information of the transmission source consumer.
The evidence data before and after acceptance of the DR from the customer side, the response data, and the information on the power consumption reduction amount are stored and accumulated in the storage device 44 of the DR server 40 every time the DR is requested.

And the evaluation part 42 reads the evidence data before and after acceptance of DR within a fixed period, the response data, and the information on the amount of power consumption reduction accumulated in the storage device 44 for the same consumer at a predetermined timing. Based on the read data, the evaluation unit 42 evaluates the degree of cooperation of the customer with respect to the DR request to the corresponding customer within the predetermined period (step S43).
The incentive calculation unit 43 calculates an incentive for the consumer based on the evaluation result by the evaluation unit 42 (step S11).

  As described above, in the device system according to the fourth embodiment, in addition to the features described in the first embodiment, when a consumer accepts a request for DR, the power control mode of the digital television 10 with built-in IHD function is set. The display device 20 is turned off by shifting to the energy saving mode, and the power consumption reduction amount at this time is reflected in the calculation of the degree of cooperation of the consumer.

  In the present embodiment, the incentive for each consumer can be calculated based on the amount of power consumption reduced by the control of the power control mode of the digital television with built-in IHD function. Since this power consumption reduction amount is determined by the specification, the accuracy of incentive calculation can be improved. Moreover, since the incentive is calculated in consideration of the amount of power consumption reduction, it becomes easier for consumers to understand the calculation result.

(Fifth embodiment)
Next, a fifth embodiment will be described. The fifth embodiment is a mode in which a function for enhancing the power saving effect by DR is added to the second embodiment by operating a plurality of digital televisions in a customer's house in cooperation with each other.

FIG. 12 is a block diagram illustrating a configuration example of a device system for performing a power demand response in the fifth embodiment.
As shown in FIG. 12, in this embodiment, the air conditioners 30 and 31 are installed in separate rooms.

A tuner 18, a display control unit 19, a display device 20, a storage device 21, and an interdigital TV communication unit 81 are included. However, the home gateway device 17 of the digital television with built-in IHD function 10 communicates with the DR server 40 via the inter-digital television communication unit 81 and the home gateway device 17 of the digital television with built-in IHD function 10.

  The inter-digital television communication unit 81 of the IHD function built-in digital televisions 10 and 10 a can communicate via the inter-digital television communication path 82. This communication path is, for example, a wireless IP network such as home Wi-Fi.

  When the energy saving operation at the time of DR acceptance is activated in one of the plurality of digital televisions with built-in IHD function installed in the home, the digital television intercommunication unit 81 is connected to the digital television with built-in IHD function in another room. However, the energy saving operation is activated. By setting it as such a structure, the effect of DR can be heightened.

Hereinafter, an operation when DR is requested by a customer will be described.
FIG. 13 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the fifth embodiment.
First, the same operations as S1 to S5 and S21 to S25 described in the second embodiment are performed. This operation is for the digital television 10 with a built-in IHD function. The device requested for the DR is the digital TV 10 with an IHD function, and the DR is not requested for the digital TV 10a with an IHD function. The acceptance or rejection of the requested DR means acceptance or rejection of the DR of the entire consumer's home including each room.

  In addition to this operation, in the digital television with a built-in IHD function 10a, the temperature acquisition unit 17c periodically acquires the temperature detected by the temperature sensor 12 regardless of the DR request, and sets it as the temperature before accepting the DR. get. Also, the illuminance acquisition unit 17d of the home gateway device 17 of the IHD function built-in digital television 10a periodically acquires the illuminance detected by the illuminance sensor 13 regardless of the DR request, and acquires it as the illuminance before acceptance of the DR. . The evidence data transmission unit 17e stores these acquisition results in the storage device 21 as evidence data before acceptance of the DR in association with the current date and time measured by the internal clock.

  After S25, the inter-digital TV communication unit 81 of the digital TV 10 with built-in IHD function sends an instruction to start an energy saving operation to the other digital TV 10a with built-in IHD function via the inter-digital TV communication path 82. To the digital television communication unit 81 (step S51). The inter-digital TV communication unit 81 of the IHD function built-in digital TV 10 a outputs an activation command from the IHD function built-in digital TV 10 to the learning remote controller 51.

  In addition, when receiving the activation command, the learning remote controller 51 of the digital television with a built-in IHD function changes the set temperature of the air conditioner 31, turns off the power of the air conditioner 31, or turns off the indoor lighting. A remote control signal is transmitted from the infrared communication unit 14. In addition, when receiving the activation command, the learning remote controller 51 of the digital TV 10 with a built-in IHD function changes the set temperature of the air conditioner 30, turns off the power of the air conditioner 30, or turns off the indoor lighting. A remote control signal is transmitted from the infrared communication unit 14 (step S52). As a result, the energy saving operation of each device in each room on the customer side is activated (step S53). As a result, not only the room in which the IHD function built-in digital TV 10 that has made the notification for the DR request is installed, but another IHD function built-in digital TV 10a that has not made the notice for the DR request is installed. Energy saving operation is also performed in the room.

  Then, the temperature acquisition unit 17c of the digital television with built-in IHD function 10, 10a acquires the temperature detected by the temperature sensor 12 as the temperature after acceptance of the DR. In addition, the illuminance acquisition unit 17d of the IHD function built-in digital television 10, 10a acquires the illuminance detected by the illuminance sensor 13 as the illuminance after acceptance of the DR.

  The evidence data transmission unit 17e of the home gateway device 17 of the IHD function built-in digital television 10, 10a associates these acquisition results with the current date and time measured by the built-in clock, and the identification information of the acquisition source IHD function built-in digital television, As evidence data after acceptance of DR, each acquisition source is distinguished and stored in the storage device 21.

  The evidence data transmission unit 17e of the digital television 10 with built-in IHD function reads the evidence data before acceptance of the DR stored in the storage device 21 in S2, and uses the evidence data before and after acceptance of the DR as the communication interface 17a, The data is transmitted to the DR server 40 via the communication network.

  Further, the evidence data transmission unit 17e of the digital television 10a with a built-in IHD function reads the evidence data before the acceptance of the DR, which is periodically stored in the storage device 21 as described above, and the evidence before and after the acceptance of the DR. Data is transmitted to the digital television 10 with built-in IHD function via the communication interface 17a and the inter-digital television communication unit 81. Upon receiving evidence data from the IHD function built-in digital television 10a, the inter-digital television communication unit 81 of the IHD function built-in digital television 10 transmits this data to the DR server 40 via the communication network. In this manner, the evidence data before and after the acceptance of the DR is transmitted from each of the IHD function built-in digital televisions 10 and 10 a to the DR server 40.

  Further, the response data processing unit 17f of the home gateway device 17 of the digital television 10 with built-in IHD function transmits response data (acceptance) to the DR server 40 via the communication interface 17a and the communication network (step S54).

  If the communication unit 41 of the DR server 40 receives response data (rejection) after S23, or if the communication unit 41 receives evidence data before and after acceptance of DR and response data (acceptance) after S54, the first In the embodiment described above, the evaluation of the cooperation degree that is S10 and the calculation of the incentive that is S11 are performed. In the present embodiment, the evaluation unit 42 obtains the degree of cooperation for each acquisition source based on response data and evidence data for each digital television with a built-in IHD function, and obtains an average value of these to obtain a home in each room. Find the overall degree of cooperation.

  As described above, in the device system according to the fifth embodiment, in addition to the features described in the second embodiment, the DR is accepted by an input operation on the digital television with built-in IHD function installed in any of a plurality of rooms. The control for power saving can be performed on the air conditioner, lighting, and other devices in each room via the IHD function built-in digital TV 10 in each room. In this way, the DR effect can be enhanced.

  Further, since the DR server 40 can obtain the evidence data captured as the energy saving action as the data for each room of the consumer's home, it is possible to calculate a more detailed incentive such as a discount on the electric power charge.

(Sixth embodiment)
Next, a sixth embodiment will be described. In the sixth embodiment, a function is added to the second embodiment in which a function for calculating a base load, which is a power usage pattern when a customer is not performing an action for power saving according to DR, is added. It is. In addition, the device system according to this embodiment calculates an incentive for the consumer by comparing the calculation result of the base load and the power used after the consumer performs an action for power saving according to the DR. It has a function.

  As shown in FIG. 3, the DR server 40 in the present embodiment includes a communication unit 41, an evaluation unit 42, an incentive calculation unit 43, a storage device 44, and a base load calculation unit 45.

Also good.

  The base load calculation unit 45 acquires room temperature data, illuminance data, operation status of each device, and weather data at a certain period when a DR is not requested in a consumer's home, and based on the acquisition result. Estimate whether the customer is at home or away from home.

  The operating status of each device is the operating status of the air conditioners 30 and 31 and the digital television 10 with built-in IHD function. The base load calculation unit 45 determines the operating status of the air conditioners 30 and 31 based on the “beep” sound and the “beep” sound during the air conditioner operation recognized via the microphone 15. Further, the base load calculation unit 45 obtains information indicating the power control mode of the digital TV 10 with built-in IHD function from the power control unit 71, thereby determining the operation status of the digital TV 10 with built-in IHD function. In addition, the weather data is temperature data and humidity data of a location near the location outside the home of the customer.

  The base load calculation unit 45 receives meteorological data from an external device that manages weather information of each place. Further, when the weather data can be measured on the consumer's IHD function built-in digital television 10 side, the base load calculation unit 45 receives the weather data from the IHD function built-in digital television 10.

  When the base load calculation unit 45 estimates that the customer is away from home, the base load calculation unit 45 insulates the outside temperature in the consumer's home based on the room temperature data, illuminance data, and weather data in the consumer's home on that day. Estimate the ability value.

  When the base load calculation unit 45 estimates that the consumer is at home, the base load calculation unit 45 estimates the value of the heat insulation capacity described above. Furthermore, the base load calculation unit 45 makes a DR request based on the value of the heat insulation capacity, the room temperature data, the illuminance data, the weather data, and the operation status of each device on the day. The base load, which is the power usage pattern in the consumer's home when not in use, is calculated.

  In the present embodiment, the incentive calculation unit 43 also includes room temperature data, illuminance data, operating conditions of each device, weather data, and a calculated base for the time period before DR acceptance on the day when a DR request is made. Based on the load, the reference power amount before accepting the DR of the day is estimated.

  The incentive calculation unit 43 saves power based on room temperature data, illuminance data, operation status of each device, weather data, and calculated base load for a predetermined time period in which DR is accepted and power is saved on this day. The amount of power used in a predetermined time zone when the above is performed is estimated.

  The incentive calculating unit 43 obtains a difference between the estimated reference power amount and the estimated used power amount in a predetermined time zone in which power is saved, and saves the difference in the energy saving power amount in the predetermined time zone in which power is saved. And

  In this embodiment, out of the economic effect amount obtained by the electric power company by performing power saving by accepting DR, the amount to be returned to the customer who cooperated with DR is defined as DR resource. The incentive calculation unit 43 distributes incentives to each customer who cooperates with the DR in such a manner that the DR resource is proportionally distributed to each customer according to the energy saving power amount described above.

Hereinafter, an operation when DR is requested by a customer will be described.
FIG. 14 is a flowchart illustrating an example of an operation procedure for performing a power demand response in the sixth embodiment.
First, the same operations as S1 to S5, S21 to S27, and S9 described in the second embodiment are performed.
After S9 or S27, as described above, the base load calculation unit 45 of the DR server 40 calculates a base load that is a power usage pattern in the consumer's home when the DR request is not made (step S61). ).

  As described above, the incentive calculating unit 43 obtains the estimated reference power amount and the used power amount in a predetermined time zone in which the estimated power saving is performed as the energy saving power amount in the predetermined time zone in which power saving is performed, An incentive for each consumer is calculated based on this energy-saving power amount (step S62).

As described above, in the device system in the fifth embodiment, in addition to the features described in the second embodiment, each customer has accepted DR even before the smart meter is fully introduced. It is possible to estimate the amount of energy saved due to the accompanying energy saving action.
Thereby, since the energy saving electric energy used as the base of energy saving action can be quantified, the incentive with respect to the consumer who accepted DR can be calculated accurately.
