  Important issues for earthquake disaster prevention include securing lifelines such as electricity and gas, and preventing furniture fixtures from falling. On the other hand, there is the development of the use of information and the transmission of emergency earthquake warnings, which are information before the main seismic wave motion arrives. And by using the earthquake early warning, it can be expected that there will be no miscontrol and the accuracy of the seismic sensitivity will be improved. Also, safer measures can be used without construction.

  Furthermore, when a large earthquake occurs, a normal power failure occurs. Thereafter, when energization is resumed, it is almost impossible to obtain 100% confirmation, although efforts are made to notify the residents of each household of the energization resume. If the damage caused by an earthquake is severe, some people will not be able to return to their homes due to severe road damage. In cases where the house is unmanned by evacuating to a evacuation center, such as when the house collapses or there is a risk of a large aftershock, a so-called energizing fire may occur. There is a possibility of becoming a major secondary fire source without being aware of the occurrence. An object of the present invention is to prevent the occurrence of such an energizing fire.

  As mentioned above, the disaster prevention system and apparatus by using the earthquake early warning for the purpose of securing lifelines such as electricity and gas and preventing the fall of furniture fixtures and the like are provided.

In view of this, the present invention is a disaster prevention system that uses emergency earthquake warnings to control household devices using emergency earthquake warnings, such as shutting off gas and electricity, and fixing devices in order to improve the safety and security of dwellings during earthquakes. Receiving means for receiving the information on the epicenter of the earthquake and the time and magnitude of the earthquake as the emergency earthquake warning before reaching the main motion of the earthquake , position information acquiring means such as GPS for acquiring the position information, and the received emergency The earthquake information calculation means for calculating the predicted arrival time and predicted seismic intensity of the main motion of the earthquake based on the earthquake early warning and the acquired position information, and comparing the predicted seismic intensity with a predetermined value to determine whether or not the predetermined value or more a judging means for, pre controlling when said prediction seismic intensity is the seismic means a device by entering the pre-treatment signal to the sensing means when not exceeding the predetermined value and sensing the arrival of the main motion of the earthquake The treatment device and the alarm device are activated when the predicted seismic intensity is equal to or greater than the predetermined value, and the device connected to the home network is controlled via the home network interface, or the device connected to the wireless link network is wirelessly connected. Forcing treatment means for controlling via a link interface.

The device having the seismic sensing means is a seismic circuit breaker, a wiring breaker for an electric heating apparatus, or an outlet.

The device connected to the home network or the device connected to the wireless link network is an electric device and gas device of a system connected to an electric heat source, an automatic lock device, or a fall prevention device .

The alarm device is characterized by announcing the number of seconds to reach an earthquake together with an alarm sound .

  Conventionally, compared with the case where the treatment is determined only by the seismic device, according to the present invention, since the treatment is determined by AND with the preliminary treatment information, erroneous control is eliminated, and the reliability of the seismic device is improved. Since it can be increased than before, safer treatment is possible. Such a procedure is effective for all devices that already have a seismoscope. Furthermore, it can be used without any construction on the housing itself, such as a socket with a seismic device. Furthermore, it becomes possible to prevent energization fires.

  In addition, according to the present invention, by utilizing the preparatory treatment and forced treatment information, a reliable disaster prevention system can be obtained for information home appliances before reaching the main motion (S wave), and the storage table can be prevented from falling. The seismic breaker and the gas shut-off function can be operated reliably.

  Hereinafter, the disaster prevention system and apparatus by the use of the earthquake early warning of this invention are demonstrated by Examples 1-2.

FIG. 1 is a diagram showing the configuration of a disaster prevention system and apparatus using emergency earthquake warning according to the present invention. As shown in FIG. 1, real-time earthquake information obtained from an earthquake observation network seismometer 1a (installed nationwide) that senses an earthquake is obtained by an earthquake information distribution center 1b such as the Japan Meteorological Agency. That is, the data collection unit 2a receives data from the seismograph network 1a. Based on the received earthquake data, the hypocenter information calculation unit 2b calculates the hypocenter information including the location of the hypocenter and the magnitude of the earthquake, and distributes it using the hypocenter information distribution unit 2c.
The real-time earthquake information utilization council 1c receives earthquake information distribution data from the Japan Meteorological Agency, etc., performs processing such as data conversion, and transmits it to the earthquake information calculation unit 14 of the disaster prevention system and apparatus according to the present invention.

  In the earthquake information calculation unit 14, the source information received by the source information receiving unit 3a and the position set by the position information setting unit 3c (input of set values, automatic acquisition of position information by the global positioning system (GPS), etc.) Based on the information, the main motion arrival time and predicted earthquake intensity at the position set by the position information setting unit 3c are calculated by the main motion arrival time and predicted earthquake intensity calculation unit 3b. Then, if the main motion arrival time and the calculation result in the predicted seismic intensity calculation unit 3b are the predicted seismic intensity 5.5 or more, the forcible treatment 19 is performed, and if the predicted seismic intensity 5.5 does not exceed, the preliminary treatment 18 is executed. (Step S15).

  Then, the home network interface 16 and the radio link interface 17 are notified. Further, the home network interface 16 is connected to the home network 25a, and the wireless link interface 17 is connected to the wireless link network 25b.

  The preliminary treatment 18 has the following functions. That is, if the predicted seismic intensity is in the range of 4.5 to 5.5 by the predicted seismic intensity calculation unit 3b, a preliminary treatment is taken and a standby state is reached until the arrival of the S wave. And the standby state until the arrival of the main motion (S wave) of the earthquake means that pretreatment information is input to the seismic device of the seismic breaker, and if the seismic device feels the S wave, the procedure is immediately executed. Keep it. Also, the pretreatment information is input to an earthquake control device having a seismic function of the gas microcomputer meter, and the shutoff valve is closed through shutoff control by S wave detection.

  Next, when the seismic intensity 5.5 or higher is predicted by the predicted seismic intensity calculation unit 3b, the forcible treatment 19 is taken. First, let the seismic appliance and other alarm devices alarm, awaken sleeping people, and make mental preparations for the earthquake. At the same time, the apparatus and the gas connected to the home network interface 16 such as a seismic breaker and a microcomputer meter are immediately shut off.

All other equipment, such as oil stoves and front doors, where forced measures are taken, will be treated.
For example, devices equipped with casters can automatically fix the casters. In the future, such pre-treatment and forced treatment information can be received when taking seismic isolation measures.

  As explained above, compared to the case where treatment is determined only with a seismic instrument, the treatment is determined by AND with the preliminary treatment information, so there is no erroneous control and the accuracy of the seismic sensitivity is now increased. Therefore, safer treatment is possible. Such a procedure is effective for all devices that already have a seismoscope.

  Then, for example, a device with casters can automatically fix the casters, and when such seismic isolation measures are taken in the future, such preliminary treatment and forced treatment information can be received.

  Next, FIG. 2 shows an example of a storage base connected to the wireless link interface 17 shown in FIG. As shown in FIG. 2, the storage table 31 is connected to the wheels 32 of the casters by a support column 35. Then, the fixed rod 37 connected to the axle of the wheel 32 comes into contact with the cover 33 of the wheel 32 and stops the rotation of the wheel 32. Therefore, the movement of the storage base 31 can be controlled by moving the fixed rod 37 in the direction perpendicular to the circumference of the wheel 32. On the other hand, the control of the fixed rod 37 is executed by the signal of the transmitter 38 via the wireless link network 25b.

  FIG. 3 shows the structure of the caster fixing rod shown in FIG. As shown in FIG. 3A, the case where the fixed rod 37 operates and the rod 44 contacts the cover 33 is shown. The fixed rod 37 is a rotary solenoid, and includes an iron core 42, a spring coil 43, and a rod 44 in the axial direction of the electromagnetic coils 41a and 41b. When the wireless receiver 39 receives the control signal (ON), the wheel 32 is fixed as shown in FIG.

  On the other hand, as shown in FIG. 3B, when the wireless receiver 39 is not receiving a control signal (OFF), the iron core 42 moves in the arrow direction, and the rod 44 is separated from the cover 33. Therefore, the wheel 32 can rotate and the storage table 31 can move.

  As home networks are standardized, there is a method of using a radio signal such as Zigbee to transmit emergency earthquake early warning.

  In addition, since it is equipped with casters, it can be applied to caster automatic locking functions and automatic interlock control functions of tipping prevention devices. In addition, various automatic developments such as automatic opening / closing of a window shutter for preventing the glass from breaking and scattering and prevention of automatic falling of the cupboard can be considered.

  As described above, according to the first embodiment, it is possible to prevent the in-home equipment from falling from an earthquake disaster by the disaster prevention system and apparatus using the emergency earthquake bulletin.

  Next, FIG. 4 shows an example of a home device connected to the home network 25a shown in FIG. As shown in FIG. 4, the earthquake information distribution center 1b such as the seismometer 1a that senses the earthquake, the earthquake information distribution center 1b such as the Japan Meteorological Agency, and the emergency earthquake bulletin distributed from the real-time earthquake information utilization council 1c via the Internet 1 10 receives. And it transmits with the home network interface 16 of the information household appliance disaster prevention system 10, and controls household appliances.

  First, the home reception control device 52 connected to the home network 25a receives the earthquake early warning, calculates the arrival time and the estimated seismic intensity in the home where the home device is installed, and the home reception control device 52 The device control signal is distributed, and the device connected to the home network 25a installed in the home is controlled.

Home electric leakage breaker 61 branches to a plurality of wiring breakers 53a and 53b and is connected to the home appliance. As an example, a case is assumed in which an electric heating device is connected to the wiring breaker 53a and a lighting device is connected to the wiring breaker 53b.
When an earthquake occurs, first, the wiring breaker 53a of the electric heating apparatus is cut preferentially for disaster prevention. For this purpose, a seismic device 62 is connected to the wiring breaker 53a and controlled.

  That is, as shown in FIG. 1, information on the preliminary treatment 18 and the emergency treatment 19 that occur when an emergency earthquake warning is received is received via the home network 25 a and transmitted to the seismometer 62. As a result, the breaker 53a for wiring is controlled to be cut according to the predicted seismic intensity, so that an electric heating appliance having a high risk of fire can be cut before reaching the main motion (S wave).

On the other hand, the luminaire is necessary for safe evacuation behavior after reaching the main motion (S wave), and there is no danger of fire prevention. Therefore, as shown in FIG. is there.
Furthermore, in order to make the seismic breaker 53a with a seismic device effective, it is effective for the house itself, such as changing the color of the outlet according to the purpose of use from the current distribution of the distribution system in the home.

  As a preliminary treatment, for example, in the case of the seismic breaker 53a shown in FIG. 5, if the pretreatment information is input to the seismic device and the seismic device 62 feels an S wave, the treatment is immediately performed. Can be kept. In addition, there is the convenience that the house itself, such as an outlet with a seismic device, can be used without construction.

  As described above, according to the present invention, it is possible to prevent an energized fire after an earthquake is restored. In addition, the seismic breaker is not cut due to the occurrence of an earthquake, but an actual power outage is detected and the breaker is turned off, so that the seismic breaker will not drop if power is maintained even in the event of an earthquake. There is.

  Next, FIG. 6 shows a gas microcomputer meter connected to the home network 25a shown in FIG. As shown in FIG. 6, the same applies to the gas microcomputer meter 55. Preliminary treatment information is input to the seismic control device 71 having a seismic function, and the gas shut-off valve 74 is set via the shut-off control device 72 by S-wave detection. close.

  Then, when the gas supply is restored after reaching the main motion (S wave), the flow rate sensor 75 and the flow meter 73 of the pipe are used for confirmation, the cutoff control device 72 is controlled, and the gas cutoff valve 74 is turned ON. In addition, a battery-powered alarm that is permanently installed in the bedroom or living room announces the number of seconds until the earthquake reaches, along with an alarm sound. Next, functions with a seismic device such as an automatic disconnection outlet for cutting off the fire source and a microcomputer meter with an automatic gas circuit breaker automatic opening / closing control function are effective.

  As described above, according to the second embodiment, it is possible to prevent household equipment from earthquake disasters by the disaster prevention system and apparatus, and it is possible to quickly secure lifelines such as electricity and gas. .
