  An embodiment of the present invention will be described in detail with reference to the drawings. Any power source may be used for relaying, but here, a case where an AC 100V power source serving as a power source for general home appliances is relayed will be described. FIG. 1 is a schematic diagram of a disaster prevention system using a power relay device according to this embodiment. As shown in this figure, the disaster prevention system is provided with a plurality of alarm devices 2 in the house, and the alarm devices 2 are connected to each other by wire to communicate with each other. Further, a power supply relay device 1 that is connected to each alarm device 2 in a wired manner, receives signals from these devices, and controls power supply from the power source is provided in the outlet box 7. Of course, the present invention can be applied to a system that uses only one alarm device 2 or a system in which the alarm devices 2 do not communicate with each other as long as an alarm signal can be transmitted from the alarm device 2 to the power supply relay device 1. Can be applied as is. In FIG. 1, the outlet box 7 uses an embedded switch box, but an exposed embedded box or other similar ones can be applied.

  In the present embodiment, the alarm device 2 will be described as an alarm device that senses (detects) smoke and warns of a fire. The alarm device 2 is configured to emit a sound alarm when smoke is detected. The alarm device 2 that detects smoke transmits an alarm signal to the other alarm devices 2 and the power supply relay device 1, and the other alarm devices. In 2, the alarm signal is received and a sound alarm is issued.

  The power relay device 1 controls the supply of power from the outlet box 7 to the external device. The outlet box 7 has an exposed portion 7a provided on the wall surface of the room and exposed to the room, and a first connection terminal 7b and a second connection terminal 7c for connecting and connecting a power supply connection portion of an external device to the exposed portion 7a.

The The power relay device may be provided separately from the outlet box 7, and when the alarm device 2 is of a wired type, in the case of a wireless system in the signal line connecting the alarm device 2 and the power relay device 1 It can be installed in an appropriate place.

  Here, the external power source is a commercial power source such as an AC 100V, for example, and is relay-controlled by the power relay device 1 and supplied to an external device as an AC 100V power source. The power supply is controlled by an external device connected to the power supply relay device 1. Here, the lighting apparatus 3 and the heating device 4 are connected as the external device. The power supply relay device 1 is also provided with an operation unit 16 that is exposed from the outlet box 7 to the room side and that can perform various operations, and a display unit 13 that displays the state of power supply relay and the operation state of the operation unit 16. ing.

Moreover, the heating apparatus 4 is a general fan heater installed indoors, and heats indoors when electric power is supplied, and stops heating when supply of electric power is stopped.

  Since the power supply relay device 1 has the configuration described below, when the alarm signal or test signal from the alarm device 2 is received, the lighting device 3 starts to supply power from the external power source, and the heating device 4 In contrast, the power supply from the external power supply is stopped. With the occurrence of an alarm, the power relay device 1 turns on the luminaire 3 so that a good field of view can be secured without being rushed even in a dark place or in an emergency at night. Accordingly, the power supply relay device 1 turns off the heating device 4, so that the heating device 4 can be automatically brought into a safe state in an emergency.

  Next, the configuration of the power supply relay device 1 will be described. FIG. 2 shows a block diagram of the power supply relay device 1. The power relay device 1 according to the present embodiment includes a receiving unit 10 that receives a signal from the alarm device 2, a power relay unit 12 that relays the supply of power from an external power source, and the content of the signal received by the receiving unit 10. And a relay control unit 11 that controls the corresponding power supply relay unit 12.

  The receiver 10 is connected to the signal line from the alarm device 2 as described above. The relay control unit 11 that performs predetermined control by a signal from the receiving unit 10 can be configured by a CPU and a memory, and can perform various processes based on a program.

  One of the power relay units 12 controlled by the relay control unit 11 is connected to an external power source, and the other is connected to the first output unit 14 and the second output unit 15. The first output unit 14 and the second output unit 15 are connected to the first connection terminal 7b and the second connection terminal 7c of the outlet box 7, respectively, to the first external device 3 and the second external device 4 via these. Power is supplied. The power supply relay unit 12 includes a switch such as a relay that can switch on / off the power supply independently for the first output unit 14 and the second output unit 15. The relay control unit 11 performs control.

  The operation unit 16 is provided with selection, cancellation, or setting means for setting the operation. The operation unit 16 is provided with a first control selection unit 21 that selects how to control the power supply relay unit 12 and actual control of the first connection terminal 7b after receiving the alarm signal. A first control start delay time setting means 23 for setting a time until the start, a second control selection means 22 for selecting how to control the power supply relay unit 12, and a second connection after receiving an alarm signal. A second control start delay time setting means 24 for setting a time until actual control of the terminal 7c is started, a control release means 25 for forcibly releasing the control of the power relay section 12 by the relay control section 11, This is control release delay time setting means 26 for setting the time until the control is actually canceled in the relay control unit 11 after the forced release operation in the operation unit 16.

  As the first control selection means 21 and the second control selection means 22, for example, a seesaw switch or a push button switch is used. As the first control start delay time setting means 23 and the second control start delay time setting means 24, for example, a dial type is used. A configuration including a timer, a slide switch or a rotary switch that can select one from several predetermined times can be applied, and setting processing is performed inside the power supply relay device 1 from a separate setting remote control device Various other configurations can be applied such as.

  In addition, the power relay device 1 is provided with the display unit 13 as described above, and the display unit 13 is connected to the relay control unit 11 and the operation unit 16, respectively. The state of control, the state of each setting in the operation unit 16, and the like can be displayed. The display unit 13 can be configured using, for example, various light emitting displays such as LEDs, a liquid crystal screen, a meter display, and the like.

  Control of the power relay unit 12 by the relay control unit 11 will be described below. FIG. 3 shows a flowchart of control in the present embodiment. When the receiving unit 10 receives any signal (S1), the relay control unit 11 determines whether it is an alarm signal or a test signal from the alarm device 2 (S2). If the signal is an alarm signal or a test signal, a control operation is performed. If the signal is not an alarm signal or a test signal, the steps of S1 and S2 are repeated until the signal stops, and the signal stops. Return to the initial state (S3).

  When the signal received by the receiving unit 10 is an alarm signal or a test signal, the relay control unit 11 reads a control operation corresponding to the state of the operation unit 16 (S4). Here, the control operation is preset by the operation unit 16, and the state is stored in the relay control unit 11.

  The relay control unit 11 starts controlling the relay operation after a predetermined time has elapsed after receiving the alarm signal. Therefore, the relay control unit 11 determines whether or not the control start delay time set by the first control start delay time setting unit 23 and the second control start delay time setting unit 24 has elapsed after receiving the alarm signal. (S5) When the time has elapsed, the process proceeds to the next step.

  The control start delay time is set by the first control start delay time setting unit 23 for the first output unit 14 and is set by the second control start delay time setting unit 24 for the second output unit 15. Therefore, when the control start delay times by these setting means are different, the start of control for the power supply relay unit 12 is delayed for different times. In the operation unit 16, the first control start time setting means 23 and the second control start delay time setting means 24 can select any time, for example, as a dial type.

  When the control start delay time has elapsed, the relay control unit 11 starts controlling the power supply relay unit 12 (S6). Here, how to control the power supply relay unit 12 is based on the setting by the first control selection unit 21 and the second control selection unit 22. In the operation unit 16, the first control selection unit 21 and the second control selection unit 22 can be configured by a seesaw switch, a push button switch, or the like as described above.

  The control for the first output unit 14 is to switch the power supply control of the power relay unit 12 to the first output unit 14 from off to on or from on to off. In the present embodiment, the lighting fixture 3 connected as the first external device is set to be turned from off to on because it is desired to be controlled from off to on at the time of alarm.

  The control of the second output unit 15 is to switch the power supply control of the power relay unit 12 to the second output unit 15 from off to on or from on to off. In the present embodiment, the heating device 4 connected as the second external device is set to be turned from on to off because it is desired to control the heating device 4 from on to off at the time of alarm.

  Therefore, in S6, the relay control unit 11 performs control to turn on the power supply to the first output unit 14 of the power relay unit 12 if it is off, and leave it on if it is on. In addition, the power supply to the second output unit 15 of the power relay unit 12 is controlled to be turned off if it is on, and left as it is if it is off.

  The relay control unit 11 causes the display unit 13 to display that control is being performed while controlling the relay control unit 11 (S7). Thereby, it can be confirmed whether the control at the time of alarm is performed by seeing the display part 13. In addition, it can be confirmed on the display unit 13 that the device is operating normally during the test. The test mentioned here is for confirming the operation of the interlocking system constructed and set by the user. For example, when a test start instruction is given by a test start instruction means such as a test switch provided in the alarm device 2, an alarm is issued. The test signal transmitted wirelessly from the device 22 is received and executed by the power supply relay device 1. Regardless of the test signal from the alarm device 22, the power supply relay device 1 may be provided with a test instruction means such as a push button switch, and the operation may be performed by the operation. A test instruction may be given from an external remote control device other than the alarm device 22, and the test instruction may be received and executed. In this case, if there is an operation of the test instruction means, a series of operations are performed after step S2 (YES) in FIG. The test instruction means may be able to instruct a test for each external device (for each external device connection terminal) to be relay-controlled, or may be able to instruct a test for interlocking with a plurality of external devices in a lump. That is, the test instruction information may be received by some means, and an external device to be tested may be selected and tested according to the received test instruction information.

  Further, during the control, it is monitored whether or not there is a forced control release operation by the control release means 25 in the operation unit 16 (S8). If there is no forced release, the control is continued as it is, but if there is a forced release operation, the control release delay time preset by the control release delay time setting means 26 elapses from the time of the forced release operation. (S9), the control state is canceled when it elapses (S10), and the initial state is restored.

  In the operation unit 16, the forcible release means 25 can be constituted by a push button switch or the like. Further, the control release delay time setting means 26 can select an arbitrary time, for example, as a dial type.

  The first connection terminal 7b and the second connection terminal 7c of the outlet box 7 connected to the first output unit 14 and the second output unit 15 have a configuration of a plug insertion port of a general AC 100V power outlet, and thus an external device. In the range of the power capacity, various devices that operate by receiving power supply from a general AC 100V power plug can be connected. Then, by selecting one of the control operations from on to off or from off to on in the operation unit 16, the operation at the time of alarm according to the external device can be arbitrarily set. Therefore, by providing the power supply relay device 1 in a general home, a system that automatically controls the electric device by an alarm signal can be constructed. Also, the system can be changed at any time by using different external devices. Furthermore, since the system is not a large-scale system, the operation check can be easily performed by providing the test function as described above.

  In the present embodiment, the first output unit 14 and the second output unit 15 are provided so as to enable on / off control of two external devices, but even if the number of connectable external devices is one. It may be three or more. Also, any external device may be used, such as a television, a disaster information radio, a rotating lamp installed outdoors, and the like. In this embodiment, a fire alarm that detects smoke by detecting smoke is assumed as the alarm 2, but a fire alarm that detects flame, heat, gas, etc., or a gas leak alarm or an earthquake alarm It may be a crime prevention alarm device such as an alarm device or an intrusion detector, or another type of alarm device, or may be an alarm device having a plurality of functions capable of detecting a plurality of abnormalities with a single device. Of course, these different types of alarm devices may be mixed in the system.

  In this way, the following system can be obtained by variously replacing the alarm device 2 and the external device. For example, when the alarm detects a fire, gas leak, or earthquake, the simple desk lamp is automatically turned on and the disaster information radio is turned on at the same time. Also, when the alarm detects an intruder on the outdoor site, a simple indoor lighting or an outdoor revolving light is automatically turned on to threaten the intruder. In addition to lighting, an external device that emits sound, such as a television or radio, may be connected and operated.

  In the present embodiment, the first control selection means 21 and the second control selection means 22 are provided so that the control for the first connection terminal 7b and the control for the second connection terminal 7c can be set independently. The number of output units may be controlled collectively for a plurality of output units.

  Furthermore, in this embodiment, the control start delay time for the first connection terminal 7b and the control start delay time for the second connection terminal 7c can be set independently, but these can also be set collectively. You may do it. On the contrary, in this embodiment, the control release delay time is set collectively and the control release is also performed collectively, but the control release means 25 and the control release are performed so that they can be set and operated independently. A plurality of delay time setting means 26 may be provided. In this case, for example, the indoor lighting and the outdoor revolving light are controlled from off to on by an alarm signal from an intrusion sensor, and the lighting that is lit is a control release unit corresponding to the external device connection terminal to which the lighting is connected. Thus, the control can be forcibly canceled and the lamp can be turned off, and only the rotating lamp can be controlled continuously.

  Further, in the present embodiment, the power relay device 1 and the alarm device 2 are connected by wire to transmit and receive signals, but the alarm device 2 is configured to be able to transmit and receive wireless signals, and the power relay device 1 The receiving unit 10 may be provided with an antenna so that a wireless signal can be received, and the signal transmission / reception between the power supply relay device 1 and the alarm device 2 may be performed wirelessly. In this case, the configuration of the power supply relay device 1 can be the same except for the receiving unit 10.

  In addition, the power supply relay apparatus 1 of the present invention includes an external connection terminal suitable for mounting the power plug or terminal with respect to an external device having a power plug or terminal appropriately unified or standardized. The purpose can be achieved by the present invention, and is not limited to the relay of commercial power. Furthermore, it is not limited to an AC 100V power source.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea. For example, in the present embodiment, the power relay device 1 is accommodated in the outlet box 7, but the power relay device 1 may be disposed outside the outlet box 7 inside the wall surface.
