The operation terminal 31, the control terminal 32, and the transmission unit 33 are connected by a pair of signal lines (two-wire signal lines) Ls.

  The remote control relays Ry1 to Ry4 are latching relay type remote control relays.

  The control terminal 32 controls the four remote control relays Ry1 to Ry4 separately.

  The operation terminal device 31 includes an operation terminal device 31a including a remote control switch having operation units S9 to S10 for individually operating loads L1 to L2, and an operation terminal device 31b including the above-described operation device. Here, when the power of the entire system in the above-described remote monitoring and control system is insufficient, the remote control transformer 34a that transforms the AC voltage of 100V and supplies the AC voltage of 24V to the operation terminal device 31b can be connected to the operation terminal device 31b. It is like that. Further, the operation terminal 31b can turn on and off a plurality of all the loads L1 to L4 with one operation unit S1 to S8.

  Here, the relation between the operation units S1 to S10 of the operation terminal 31 and the remote control relays Ry1 to Ry4 connected to the control terminal 32 is associated, and addresses are assigned to the operation terminal 31 and the control terminal 32. . In addition, you may make it respond | correspond one-to-many other than making the relationship of operation part S1-S10 of the operation terminal device 31 and the remote control relays Ry1-Ry4 connected to the control terminal device 32 correspond one-to-one.

  The transmission unit 33 is a memory unit (not shown) that stores a control table that is a data table in which the relationship between the operation units S1 to S10 of the operation terminal 31 and the remote control relays Ry1 to Ry4 connected to the control terminal 32 is associated. )). Further, the transmission unit 33 constantly polls the pair of signal lines Ls for transmitting the transmission signal Vs as shown in FIG.

  As shown in FIG. 9, the transmission signal Vs includes a start pulse signal SY indicating the start of signal transmission, a mode data signal MD indicating the signal mode, an address for individually calling the operation terminal 31 and the control terminal 32 (operation terminal). Address data signal AD for transmitting data, control data signal CD for transmitting control data for controlling loads L1 to L4, and checksum data for detecting transmission errors A bipolar (24V AC voltage) pulse width modulation signal including a signal return period WT which is a time slot for receiving a return signal from the signal CS, the operation terminal 31 and the control terminal 32 is used. Note that the operation terminal 31 and the control terminal 32 secure driving power by full-wave rectifying the transmission signal Vs.

  Hereinafter, an example of the operation of the above-described remote monitoring control system will be described.

  For example, when all of the loads L1 to L4 are in the off state and the person operates the operation unit S2 of the operation terminal device 31b to turn on the load L2, the person operates the operation unit S2 of the operation terminal device 31b. The control data signal CD shown is notified to the transmission unit 33 by the transmission signal Vs. The transmission unit 33 controls the control terminal 32 associated with the operation unit S2 of the operation terminal 31b to control the remote control relay Ry2 based on the control table stored in the memory unit of the transmission unit 33. The data signal CD is notified by the transmission signal Vs. The control terminal 32 turns on the load L in the remote control relay Ry2 according to the transmission signal Vs notified from the transmission unit 33.
