  FIG. 6 shows a connection circuit between the power conversion unit 5 and the battery unit B of the present embodiment. The illustrated power conversion unit 5 rectifies and smoothes a single-phase, three-wire, 200 V commercial AC power supply, And a DC / DC converter 5B for stepping down the DC voltage obtained by the rectifier circuit 5A and converting it to a predetermined DC voltage, from the DC / DC converter 5B to the conductive bar 8, 8, DC power is supplied to each of the communication units 6 a and 6 b and the communication control units 6 c, 6 d, and 6 e.

  In addition, the power converter 5 connects the resistor R1 to the electric circuit between the rectifier circuit 5A and the DC / DC converter 5B, and detects a power failure of the commercial AC power source from the voltage across the resistor R1. A current sensor 5D that detects a current output from the rectifier circuit 5A, and a current monitoring unit 5E that monitors an input current of the power conversion unit 5 from a current detected by the current sensor 5D, and a voltage detection unit 5C. When the voltage detected in the above becomes a predetermined value or less, when the current monitoring unit 5E detects a function as a power failure detection unit that transmits a control signal to the battery unit B through the communication unit 5F, and that the monitored input current exceeds a threshold value. A control unit 5G having a function of transmitting a control signal to the battery unit B through the communication unit 5F in the same manner as when a power failure is detected, and a function of controlling the operation of the DC / DC converter 5B. It is provided.

  On the other hand, the battery unit B turns on / off the storage battery module 9A composed of the secondary battery group and connecting the storage battery module 9A to the electric circuit between the rectifier circuit 5A in the power converter 5 and the DC / DC converter 5B. The switch circuit 9B includes a battery control unit 9D that performs control to turn on the switch circuit 9B while the control signal from the power conversion unit 5 is received via the communication unit 9C. The DC voltage of the storage battery module 9A is input to the DC / DC converter 5B, and the storage battery is transferred from the DC / DC converter 5B to the communication units 6a and 6b and the communication control units 6c, 6d and 6e via the conductive bars 8 and 8. The DC power of the module 9A is supplied. In addition, while direct current is output from the rectifier circuit 5A of the power conversion unit 5, a charging current flows through the diode D through the storage battery module 5A in the battery unit B due to the output. The switch circuit 9B turns on / off the connection of the positive electrode of the storage battery module 9A and passes through the negative electrode for charging.

  Thus, in FIG. 1, the commercial control power is converted into direct current power by the power conversion unit 5 and supplied to the communication control unit 6c through the conductive bars 8 and 8, and the communication control unit 6c is operated. The operation of controlling the lighting of the LED lighting terminal 11 can be performed in accordance with an operation instruction using the unit 19.

  That is, when there is an instruction for full lighting by operating the operation unit 19 during turning off or dimming lighting, the communication control unit 6c continuously turns on the switch circuit 18b to set the maximum lighting power amount to the LED lighting terminal 11. To turn on all the LEDs. On the contrary, if there is an instruction to turn off during lighting, the switch circuit 18b is turned off, power supply to the LED lighting terminal 11 is stopped, and the LED is turned off.

  On the other hand, if there is an up or down dimming instruction from the operation unit 19 during lighting, the on-duty of the switch circuit 18b is gradually reduced or increased according to the dimming instruction operation period and supplied to the LED lighting terminal 11 The amount of electric power is changed, and the lighting of the LED is dimmed and controlled.

  Next, for example, when the disaster prevention sensor 12 detects the occurrence of a fire and the detected information is sent to the communication control unit 6c through the signal line 16 by the carrier signal S, the communication control unit 6c receives it by the carrier communication unit 19b. The detection information is passed to the control unit 19c. When the control unit 19c receives the detection concession information, the control unit 19c transmits the cooperation relationship information as the transport signal S from the transport communication unit 19b to the communication control unit 6c connected to the LED lighting terminal 11 that is the target of the cooperation operation in advance.

  Here, the communication control units 6c, 6d, and 6e (and the communication units 6a and 6b) are set with unique identification addresses in the carrier communication. It is assumed that the transmission source address information is also attached to the header.

  When the control unit 18d of the communication control unit 6c receives the cooperation relationship information addressed to itself via the transport communication unit 18e, the control unit 18c controls the on / off operation of the switch circuit 18b in advance corresponding to the operation mode corresponding to the cooperation operation. To do. In other words, the duty ratio is controlled to control the light emission of the LED lighting terminal 11, or the power supply is turned on / off at a predetermined cycle to blink at a predetermined cycle. The user knows the occurrence of a fire from 11 lighting states.

  Even when the security sensor 13 connected to the communication control unit 6e by the signal line 17 detects an illegal intrusion (control factor), if a series of cooperative operation processes are performed as in the case of the disaster prevention sensor 12, an illegal person is detected. Can be informed of intrusion. In this case, if control is performed so that the lighting state of the LED lighting terminal 11 is different between when a fire is detected and when a trespassing is detected, whether the LED lighting terminal 11 is on or off can be distinguished from the lighting state. And the corresponding treatment can be performed quickly.

  By the way, the communication control unit 6c described above controls the lighting power amount of the LED lighting terminal 11 by controlling on / off of the DC voltage for supplying DC power to the LED lighting terminal 11 by the switch circuit 18b. However, instead of performing on / off control of the switch circuit 18b, the dimming control information is transmitted to the LED lighting terminal 11 from the carrier communication unit 18e by the carrier signal S that is superimposed on the DC voltage on the feeder line 15. You may send it.

  In this case, as shown in FIG. 7, the LED lighting terminal 11 controls the lighting power amount of the light emitting unit 11a by turning on / off the DC voltage similarly to the light emitting unit 11a composed of the LED group and the above-described switch circuit 18b. The control circuit 11c that extracts the dimming control information from the switch circuit 11b and the carrier signal S sent superimposed on the DC voltage, acquires the control contents, and controls the operation of the switch circuit 11b according to the control contents. And. The operating power supply of the control unit 11c is obtained from the DC voltage supplied.

  Thus, according to the circuit configuration of FIG. 7, when a plurality of LED lighting terminals 11 are controlled by one communication control unit 6c, a unique address is given to each LED lighting terminal 11, and dimming is performed together with the unique address information. If the control information is sent by the carrier signal S, each LED lighting terminal 11 can be controlled. Therefore, it becomes possible to designate the LED lighting terminal 11 to be turned on during the cooperative operation based on the detection information of the disaster prevention sensor 12 or the security sensor 13 described above, and a plurality of LEDs are controlled under one communication control unit 6c. Even if there is the lighting terminal 11, the lighting control of the predetermined LED lighting terminal 11 can be performed, and the distinguishability when notifying the user of the occurrence of a fire or illegal intrusion can be improved.

  The power conversion unit 5 sends a power failure detection signal to the communication control unit 6c that is an LED controller, and the communication control unit 6c performs dimming control of the LED lighting terminal 11 at a predetermined level so as to reduce power consumption. May be.

  Although the above-described communication information (communication control units 6c, 6d, 6e) is exchanged using the carrier signal S superimposed on the DC voltage on the conductive bar 8, the DC voltage is transmitted at a high frequency. You may make it transmit using the pulse signal obtained by making it intermittent. Further, as shown in FIG. 8, the dedicated communication line 20 may be used, and the communication information may be exchanged by the communication unit 21 provided via the communication line 20.

  Further, in the system of FIG. 1, the battery unit B is provided in the switchboard 1 ′. However, as shown in FIG. 9, one or more power storage modules 9A are provided on the battery storage board 1 ″ separately from the switchboard 1 ′. A battery unit B that is housed and configured may be used.

  Furthermore, as shown in FIG. 10, the configuration in the distribution board 1 ′ may be incorporated in the distribution board 1. In FIG. 10, the battery unit B is provided separately, but of course, it may be installed in the distribution board 1. In addition, when the battery unit B is installed in the switchboard 1 ′ or the distribution board 1, the battery unit B may be configured by connecting one or more storage battery modules to the conductive bar 8. In this case, the conductive bar 8 is used. Then, it is charged with DC power from the power conversion unit 5 and is backed up directly from each power storage module via the conductive bar 8 in the event of a power failure.

  Further, in the above-described system, the link-related information is sent from the communication control unit 6d or 6e on the sensor side to the address of the communication control unit 6c on the facility device side that is the cooperative operation target. The information is transmitted as linkage information without specifying a destination, and the linkage information is transmitted on the conductive bars 8 and 8 (or the communication line 20) in the communication control unit (6c in the embodiment) on the equipment side. When this cooperation relation information is received, the detection information that is the cooperation relation information matches the detection information content registered in advance in association with the cooperation operation in the communication control unit (6c in the embodiment). The terminal (the LED lighting terminal 11 in the embodiment) may be controlled with the contents associated with the detection information.

(Embodiment 2)
In the first embodiment, the correspondence relationship of the cooperative operation and the cooperative correspondence information such as the combination of the cooperative operation target and the cooperative operation content necessary for the cooperative operation are set and registered in advance in the corresponding communication control units 6c, 6d, and 6e. However, it is not possible to deal with any change in the correspondence such as system expansion or reduction. Therefore, in the present embodiment, the cooperation control unit 6f for the cooperation operation is provided as a communication device as shown in FIG.

  In other words, this cooperative control unit 6f is also connected to the conductive bar 8 by plug-in connection and operates by receiving direct-current power and is input from the conductive bar 8 as shown in FIG.

The cooperation control unit 6f searches for the corresponding communication control unit (communication control unit 6c, which is an LED controller in the embodiment) based on the received cooperation relation information and the cooperation correspondence information registered in the memory unit 22c. Control information corresponding to the above-described detection information is sent to the communication control unit 6c by the carrier signal S as linkage information (II).

  The communication control unit 6c performs processing for controlling the operation of the LED lighting terminal 11 based on the information on the cooperative operation content sent to itself.

  In this way, the cooperative operation control according to the present embodiment registers the above-mentioned cooperative correspondence information in the cooperative control unit 6f, thereby changing the combination relation of the cooperative operation target and changing the control content to the communication control units 6c and 6d. 6e side can be changed without change, so that the expansion and reduction of the system can be dealt with freely, and a cooperative operation control system using a communication control unit other than the communication control unit described above is constructed. Is easy to do.

  Also, registration of data such as cooperation correspondence information in the memory unit 22c is sent to the communication unit 6a from, for example, a server (not shown) provided on the Internet NT side, and the communication unit 6a temporarily downloads this data to a buffer or the like. Then, the data may be transferred to the cooperation control unit 6f using the carrier signal S, and the transferred data may be stored in the memory unit 22c by the cooperation control unit 6f to perform the registration process.

  In this case, a change in cooperation correspondence information, new setting, and further maintenance can be remotely operated by a contractor (manufacturer) and the like, so there is no burden on the user. It is assumed that an operation program such as a download procedure and a registration process is preinstalled in the control unit (not shown) of the communication unit 6a and the control unit 22b of the cooperation control unit 6f. The memory unit 22c to be used may be a memory unit built in and fixed to the cooperation control unit 6f, or may be a removable memory unit as described above.
