Description: TECHNICAL FIELD The present invention relates to a centralized monitoring control device that centrally monitors an operation input and centrally controls a load based on the operation input.

BACKGROUND ART Conventionally, a centralized control device of this type, which centrally monitors an operation input and centrally controls a load based on the operation input, has a central controller 1 and an individual switch SW as shown in FIG. ₁ , SW ₂ ...... Individual monitoring terminal 2a for monitoring individual operation input by SW2, pattern monitoring terminal 2b for monitoring pattern operation input by pattern operation switch SWp, and load

Connected to the central control unit 1 to access the monitoring terminals 2a, 2b to return the monitoring data, and control data for individually controlling or pattern controlling the load formed based on the monitoring data from the central control unit 1. The control terminal 3 is accessed and transmitted. FIG. 8 shows an example of the transmission signal Vs transmitted from the central control unit 1. The transmission signal Vs transmitted as a bipolar signal includes a start signal ST indicating the start of signal transmission and each monitoring terminal 2a. , 2b and an address data signal AD for transmitting address data for accessing the control terminal 3, a control data signal CD for transmitting control data to the control terminal 3, and a return waiting period signal WT. , Each data is transmitted by pulse width modulation. In addition, each monitoring terminal 2a, 2b
Alternatively, the return signal V _B for returning the monitoring data or the control confirmation signal from the control terminal device 3 to the central control unit 1 is a current mode signal (a low resistance is appropriately connected between the signal lines 4 in synchronization with the return waiting period signal WT. Signal obtained by the above). In each of the monitoring terminals 2a and 2b and the control terminal 3, the transmission signal Vs is rectified and smoothed to obtain a circuit power supply.

By the way, in such a conventional example, since the pattern monitoring terminal 2b is a floor-installed type in which the pattern operation switch SWp is integrated and installed on the wall surface, a device installed in the distribution board (for example, When performing pattern operations from the timer unit), it is not possible to easily wire to the pattern monitoring terminal 2b because there is no pattern operation input terminal, and the operation input wires must be pulled out from the distribution board.
Since there is no bf, there is a problem that the wiring work is troublesome. Also, in order to facilitate wiring, pattern monitoring terminals
When the 2b is to be stored in the distribution board, the shape of the distribution board is not set to the agreement size of the distribution board, which causes a problem of troublesome wiring work.
