Description

  The present invention relates to a seismic isolation system that stops power supply in response to an earthquake.

Conventionally, there is a seismic isolation system that stops the supply of power in response to the occurrence of an earthquake. In such a seismic isolation system, elevators and automatic doors etc. can not be stopped suddenly for safety reasons, so control is performed so that certain conditions are provided and the shutdown operation is delayed without stopping the supply of power immediately. doing.
For example, in Patent Document 1, even if an earthquake occurs, the entire distribution board is not shut off, and power interruption is performed at the time of power recovery after the occurrence of a power failure, so that it is not inconvenient for the resident Control to prevent a fire from occurring when a power failure recovers and power is restored.
On the other hand, there has been proposed a system which receives an earthquake and activates a camera installed inside the home to take an image and transmits the captured image to a portable terminal carried by a resident outside the home (for example, Patent Document) 2).

The LAN-IF 47 is connected to the public communication network N via the modem 8 and can communicate with the portable terminal 7 via the public communication network N.

  Note that the notification unit CPU 50 stores in advance the telephone number or the address data of the portable terminal 7 carried by the resident and stores the same. Communication with the portable terminal 7 via the LAN-IF 47 under the control of the notification unit CPU 50 Is done. Further, although the power supply unit 51 obtains a commercial power supply from a wall outlet or the like and outputs a DC voltage, the power supply unit 51 incorporates a battery so as to operate at the time of a power failure.

  As shown in FIG. 5, the camera unit 6 receives a camera 65 that picks up an installed room, a sound collection unit 66 that picks up the sound of the room, and an earthquake occurrence signal sent from the control unit 2. A camera unit wireless unit 67 that communicates with the unit 4, a camera unit CPU 68 that controls the camera unit 6, and a power supply unit 69 that supplies power to each unit of the camera unit 6 are provided. Similarly to the notification unit 4, the power supply unit 69 obtains a commercial power supply from a wall outlet or the like and outputs a DC voltage, but incorporates a battery to operate at the time of a power failure.

  The operation of the seismic isolation system configured in this way is as follows. First, as initial setting, the seismic intensity to be subjected to shutoff control and the delay time for delaying and outputting the signal to shut off the main electric path are set. The seismic intensity to be subjected to cutoff control is set by the sensitivity setting unit 44 of the notification unit 4. For example, the selected sensitivity information is selected from seismic intensity 5 low, seismic intensity 5 high and seismic intensity 6 and is set by the notification unit CPU 50 and transmitted from the wireless unit 48 to the control unit 2 and the control unit 2 senses this information. Transmit to the quake sensor 1. The seismic sensor 1 stores the seismic sensor CPU 12 in the set seismic intensity storage unit 11, and the sensitivity is set.

  The delay time is set by operating the delay time setting unit 45. A predetermined time (delay time) from when an earthquake is detected to when the breaker trip circuit 24 outputs a signal is set. For example, 1 minute, 3 minutes, 7 minutes, etc. are selected and set, and the set delay time is transmitted to the control unit 2 in the same manner as the seismic sensitivity setting, and the control unit CPU 25 controls the delay of the control unit 2 It is stored in the time storage unit 25a.

Thus, when the initial setting is completed, the system is in a standby state. Thereafter, when an earthquake occurs, the seismic sensor 1 outputs an earthquake detection signal to the control unit 2 when judging that the earthquake having the seismic intensity set, for example, the seismic intensity 5 or higher, has occurred by judging the seismic intensity.
In the control unit 2 that has received the earthquake detection signal, an earthquake occurrence signal is transmitted from the wireless unit 23 under the control of the control unit CPU 25, and is transmitted to the outlet unit 3, the notification unit 4, and the camera unit 6. The wireless unit 23 performs communication using, for example, a 920 MHz band signal.

  At the same time, the control unit CPU 25 starts counting the delay time, and outputs a delay shutoff signal for batch shutoff to the breaker trip circuit 24 when the delay time stored in the delay time storage unit 25a is reached. In response to the delay shutoff signal, the breaker trip circuit 24 causes the leak breaker 5 to flow a pseudo-leakage current to cause it to shut off. If this leakage breaker 5 is used as a master breaker of the distribution board, all the electric paths in the dwelling unit are cut off collectively.

  In the outlet unit 3 receiving the earthquake occurrence signal transmitted from the control unit 2, the trip coil drive circuit 34 operates and the trip coil 33 trips under the control of the outlet unit CPU 37. Thus, the contact 32 is opened and the electric path L2 leading to the outlet 31 is cut off.

  In the camera unit 6 that has received the earthquake occurrence signal, the camera 65 is activated under control of the camera unit CPU 68 to start imaging, and the sound collection unit 66 is activated to start sound collection. The video data captured in this manner and the collected sound data are wirelessly transmitted from the camera unit wireless unit 67 to the notification unit 4.

On the other hand, in the notification unit 4 that has received the earthquake occurrence signal, the voice synthesis IC 42 generates a message under the control of the notification unit CPU 50, and for example, “The earthquake was detected from the speaker 41. All power supplies will be shut down soon” It is sounded. In addition, the display of the display unit 43 is changed from blue to red.
Furthermore, when the video information and the sound information received from the camera unit 6 are received, it is transmitted to the mobile terminal 7 registered in advance together with the earthquake occurrence information. This information is transmitted via the LAN-IF 47, the modem 8 and the public communication network N. In the portable terminal 7 having received this information, when the predetermined display operation is performed, the image of the room is displayed together with the earthquake occurrence information, and the sound information is further output.

As described above, in the case of a distribution board or the like, batch blocking can be delayed by the delay blocking signal output by the control unit 2 when an earthquake occurs. And the power source of the electric equipment which should be immediately cut off at the time of an earthquake occurrence can be interrupted by an earthquake occurrence signal, and coexistence of prevention of a fire occurrence and security of a resident can be attained. Further, in order to carry out the immediate shutoff in the outlet 31, there is no need to arrange the line to be shut off immediately from the line to be shut off all at once, which can be configured at low cost.
Furthermore, in addition to the notification of the occurrence of the earthquake, the indoor video is also transmitted to the portable terminal 7 carried by the resident, so that the resident who is out can grasp the situation of the home in addition to the earthquake occurrence information and can be relieved It is possible to cope from where you go out according to
In addition, since no wiring is required between the camera unit 6 and the notification unit 4, the camera unit 6 can be installed at an arbitrary place, and sound information can be obtained in accordance with the display of the image on the portable terminal 7, It is easy to grasp the situation of
Furthermore, since no wiring is required between the control unit 2 and the outlet unit 3, installation of the outlet unit 3 is easy.

Although the camera unit 6 wirelessly receives an earthquake occurrence signal from the control unit 2, the camera unit 6 and the control unit 2 may be connected by wire.
Further, although the vibration sensor 1 and the control unit 2 are separately provided, they may be integrated. Furthermore, the outlet unit 3 and the camera unit 6 may be plural.
