Description

  The present invention relates to prevention of an electric fire due to a disaster, and an electric power shut-off system that shuts off a power source of an electric device or the like having an electrothermal conversion function when a vibration of a predetermined value or more is detected, and a seismic device and a power shut-off used therefor Relates to the device.

  There are cases where houses are exposed to fires due to the occurrence of earthquakes. Preventing the occurrence of this fire (secondary disaster) is also important to prevent the disaster from spreading. Therefore, as shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 10-21814), a technique has been proposed in which the breaker lever is lowered in accordance with the shaking of the earthquake to cut off the energization.

  However, as described in Patent Document 1, when a power cut-off device is installed independently for an arbitrary outlet, a certain power cut-off device is activated when an earthquake occurs. There is a possibility that the device may vary such that the shut-off device does not operate.

  In addition, when the power supply is shut down for the entire house in response to an earthquake, the power supply in the house is cut off when the earthquake occurs if the system is configured to shut off the power supply using a power supply line or switchboard. For this reason, for example, the lamps in the hallway may not light up, and evacuation may be difficult.

  In addition, according to the recommendations of the administrative agency, we expect consumers to take safety measures (for example, turn off the breaker or unplug the electrical plug) in the event of a disaster or leaving the house. In particular, when a disaster occurs, various objects fall into the room and the position of plugs and outlets cannot be seen, and consumers are often panicked by disasters. You cannot expect cool behavior.

  A power shut-off system to which the present invention is applied is installed in a house or the like, and controls the supply of power in the entire house for each outlet in the event of a disaster such as an earthquake disaster.

  Specifically, as shown in FIG. 1, a power shutoff system 1 to which the present invention is applied includes a master unit 10 connected to a wall outlet 2 for an air conditioner or the like provided in a house, and a floor side of a room. And one or a plurality of slave units 30 connected to the wall socket 3 provided. The base unit 10 is connected to, for example, a wall outlet 2 for an air conditioner on the ceiling side which does not disturb the resident's life. Moreover, the subunit | mobile_unit 30 is connected to the wall-side outlet 3 on the floor side which a resident uses daily. Among the plurality of wall outlets 3 provided on the floor side, the slave unit 30 is connected to the wall outlet 3 to which an electric device 4 having an electric heat conversion function such as an electric heater, a water tank heater for heating water in the water tank, and the like is connected. Connected. That is, both the parent device 10 and the child device 30 function as a wiring connection device. In addition, when the base unit 10 senses a relatively large earthquake, that is, vibration, the base unit 10 transmits a power-off signal to the slave unit 30. The subunit | mobile_unit 30 is provided with the interruption | blocking switch, and when a power supply interruption | blocking signal is received, a interruption | blocking switch is turned off and the power supply to the connected electrical equipment is stopped forcibly. In this respect, the master unit 10 functions as a seismic device, and the slave unit 30 functions as a power shut-off device.

  As described above, the base unit 10 to which the present invention is applied is a seismic device connected to a wall outlet 2 or the like for an air conditioner on the ceiling side, and is connected to the wall outlet 2, Further, the plug of the air conditioner 4 as an electric device is connected so that the power from the wall socket 2 can be supplied to the air conditioner 4. Specifically, as shown in FIG. 2, the base unit 10 has a first outlet input unit 11 having a plug terminal blade inserted into an insertion hole of the wall outlet 2 and a plug terminal blade of the air conditioner 4 inserted therein. A first outlet output unit 12 having an insertion hole, a vibration detection unit 13 that detects vibration, a CPU (Central Processing Unit) that determines whether the vibration detected by the vibration detection unit 13 is equal to or greater than a predetermined value, and the like. When the first control unit 14 and the first control unit 14 detect a vibration greater than or equal to a predetermined value, the transmission unit 15 performs a transmission process for transmitting a power cutoff signal, and the power cutoff signal subjected to the transmission process And an antenna 16 for transmitting. In addition, a first power supply unit 17 is provided to supply power input from the first outlet input unit 11 to each component such as the first control unit 14 and the transmission unit 15.

  The vibration detection unit 13 is a vibration sensor that responds to a specific acceleration. The first control unit 14 can detect a vibration corresponding to a seismic intensity of 5 for example. Specifically, the first control unit 14 stores a specific acceleration duration corresponding to the earthquake in the internal memory as a predetermined value. The first control unit 14 generates a power cutoff signal when the specific acceleration continues for a predetermined time or longer, and outputs the power cutoff signal to the transmission unit 15.

  In the power shut-off system 1 to which the present invention is applied, transmission of a power shut-off signal from the master unit 10 to the slave unit 30 uses a predetermined wireless standard (for example, IEEE 802.15.4 standard, ZigBee (registered trademark)). Using a wireless sensor network (WSN, Wireless Sensor Network), it is possible to achieve small size, light weight, low cost, power saving, automatic network construction, etc. suitable for short-range wireless communication for home appliances. Therefore, the transmission unit 15 performs communication processing according to a predetermined wireless standard on the power cutoff signal input from the first control unit 14 and transmits the power cutoff signal subjected to the communication processing from the antenna 16. .

  Further, the first control unit 14 indicates that a small-scale earthquake has occurred when the duration of a specific acceleration is shorter than the predetermined time described above than the earthquake with a seismic intensity of 5 or higher, such as seismic intensity 3 or vibration 4. A warning will be issued to the person. The first control unit 14 may be provided with a further predetermined value so as not to react to vibrations generated in daily life. For example, as a further predetermined value, the duration of the specific acceleration is shorter than the above-mentioned predetermined time.

  The first power supply unit 17 is connected to the first outlet input unit 11 and supplies predetermined power to each component such as the first control unit 14 and the transmission unit 15.

On the other hand, when an earthquake occurs first in a substation or the like and power transmission is stopped and a power failure occurs, power is not supplied to the first outlet input unit 11. Therefore, the power storage unit 17a stores power enough to drive each component such as the first control unit 14 for a predetermined time, for example, 8 seconds, even when power is not supplied to the first outlet input unit 11. In addition, each component such as the first control unit 14 operates even during a power failure.

  Further, the base unit 10 is connected to the first outlet input unit 11 to detect a power failure, a power failure detection unit 18, and an illumination unit 19 composed of a plurality of LEDs (Light-Emitting Diodes) that are turned on at the time of the power failure.

  The first operation unit 23 includes, for example, a push button, and is a reset button for resetting the operation or a test button for transmitting a test signal to the slave unit 30. When the reset button is pressed, the first control unit 14 resets the operation, and when the test button is pressed, the first control unit 14 outputs a power cutoff signal from the antenna 16. Note that the first operation unit 23 is not limited to these buttons, and other operation buttons for setting the first predetermined value and the second predetermined value may be provided. .

  Further, the first control unit 14 performs a sound process on the first sound processing unit 24 and emits a sound from the first speaker 25 when a predetermined value, that is, a specific acceleration is equal to or longer than a predetermined time. . For example, the first control unit 14 reads out a voice message such as “shuts off power” from the internal memory, performs a D / A conversion process or the like in the first voice processing unit 24, and sends the voice message to the first message. The sound is emitted from the speaker 25 and notified to the resident.

In addition, when the warning sound is simply emitted, the first sound processing unit 24 may be omitted. Further, the vibration detection unit 13 is not limited to the above example.

  As described above, since the base unit 10 needs to be mounted with the vibration detection unit 13 in a vertical state, it is connected to the first wall socket 2 for the air conditioner 4. However, the vibration detection unit 13 vibrates even in the sideways state. If it has the function which can detect, the outlet etc. which were provided in the ceiling for illumination may be sufficient. That is, it is preferable that the base unit 10 is connected to an outlet in a place where the resident does not use it everyday and does not disturb his life. Further, the predetermined value stored in the internal memory of the first control unit 14 is not fixed, but may be arbitrarily set by the resident operating the first operation unit 23.

The second display unit 39 is lit when the slave unit 30 is connected to the wall socket 3 and is operating.

  The 2nd operation part 41 is comprised by the push button, for example, and is a utilization start button. When the use start button is pressed, the second control unit 37 enters a standby state for receiving a power-off signal. In addition, when the second control unit 14 receives a power-off signal from the parent device 10, the second control unit 14 performs sound processing on the second sound processing unit 42 and emits the sound from the second speaker 43. For example, when the second control unit 37 receives a power cutoff signal, the second control unit 37 reads out a voice message such as “Power is cut off” from the internal memory, and the second voice processing unit 42 performs a D / A conversion process or the like. And a voice message is emitted from the second speaker 43 to notify the resident.

  Note that the second control unit 37 may emit a beep sound or the like from the second speaker 43 as a warning sound. Further, when the warning sound is simply emitted, the second sound processing unit 42 may be omitted.

  In addition, although the case where the electric device having the electrothermal conversion function such as the electric heater 5 and the water tank heater 6 was connected to the child device 30 was described, the child device 30 includes a washing machine, a washing dryer, and a television receiver.
