[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a remote monitoring control system for monitoring and controlling a load, and is used for mounting an operation terminal having a switch for operating a load on a construction surface. It is about the frame.

[0002]

2. Description of the Related Art Conventionally, a plurality of operation terminals and control terminals are connected to a signal line by a time division multiple access system, and operation data generated by operating a switch with an operation terminal having a switch. A remote monitoring control system is provided in which control data is created based on the control data, and the control data is transmitted to a control terminal connected to the load, so that the operation state of the load corresponds to the operation of the switch. .

[0003] The remote monitoring and control system is configured, for example, as shown in FIG. That is, the transmission processing device 81 includes a plurality of operation terminals 82 for monitoring the operation state of the switch SW, and a plurality of control terminals 8 for controlling the load L.
3 and the like are connected via a two-wire signal line Ls. Individual addresses are set in the operation terminal 82 and the control terminal 83, respectively, and the transmission processing device 81 uses the addresses to operate the transmission terminal 81 and the control terminal 83.
Are individually recognized.

[0004] The transmission processing device 81 transmits a signal to the signal line Ls.
A transmission signal Vs having a format as shown in FIGS. 8A and 8B is transmitted. That is, the transmission signal Vs includes a start pulse ST indicating the start of signal transmission, a mode data signal MD indicating a signal mode, and an address data signal transmitting address data for individually calling the operation terminal 82 and the control terminal 83. AD, a control data signal CD for transmitting control data for controlling the load L, a checksum data signal CS for detecting a transmission error, a time slot for receiving a return signal from the operation terminal 82 or the control terminal 83 Is a multipole (± 24 V) time-division multiplexed signal having a signal return period WT, and data is transmitted by pulse width modulation.

In each operation terminal 82 and each control terminal 83, if the address data transmitted by the transmission signal Vs received via the signal line Ls matches the address data set in advance, the transmission signal Vs And return control data as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate low impedance) in synchronization with the signal return period WT of the transmission signal Vs.

Further, the transmission processing device 81 is provided with a dummy signal transmitting means and an interrupt signal processing means. The dummy signal transmitting means sets the mode data signal MD to the dummy mode, and sets each operation terminal 82 and control terminal 83
, A dummy transmission signal having a free address not set as address data is always transmitted. Further, when the interrupt signal processing means receives the interrupt signal Vi generated in any one of the operation terminals 82 as shown in FIG. 8C, the interrupt signal processing means detects the operation terminal 82 which has generated the interrupt signal. The access terminal 82 is accessed to return the reply data. That is, the dummy signal is normally transmitted to the signal line Ls by the dummy signal transmission means, and the interrupt signal Vi generated from the operation terminal 82 in response to the operation of the switch SW is changed to the start pulse signal S of the dummy transmission signal.
When the transmission is detected in synchronization with T, the transmission signal Vs in which the mode data signal MD is set to the address confirmation mode is transmitted from the transmission processing device 81 by the interrupt processing means. In the address confirmation mode, the operation terminals 82 having a part of the common address are grouped, and the transmission signal Vs is collectively transmitted for each group. When receiving the transmission signal Vs in which the mode data signal MD is in the address confirmation mode, the operation terminal 82 that has generated the interrupt signal Vi synchronizes with the signal return period WT of the transmission signal Vs to operate the operation terminal 82.
Is returned as reply data. In this way, the transmission processing device 81 acquires the address of the operation terminal device 82 that has generated the interrupt signal Vi, and accesses the operation terminal device 82 using the acquired address, thereby connecting to the operation terminal device 82. Operation data corresponding to the operated state of the switch SW is received as return data.

In the transmission processing device 81, an operation terminal 82
Based on the operation data returned from, the control data to be transmitted to the control terminal 83 connected to the load L whose correspondence with the switch SW is set in advance is created, and the transmission signal Vs including the control data is generated. The data is transmitted to the signal line Ls, and the control data is transmitted to the corresponding control terminal 83 to control the load L.

The operation terminal 82 can connect up to four independent switches SW, and the control terminal 83 can connect up to four independent loads L. It is configured. That is, the operation terminal 8 to which the same address data is set
2 and the control terminal 83 are further set with load number data of 2 bits each, so that up to four switches SW and loads L can be identified.

By the way, the case of the conventional operation terminal device 82 is standardized for the embedded wiring device so that it can be constructed in the same manner as the embedded wiring device standardized in the JIS standard or the like. The external shape and dimensions are set so that it can be attached to a mounting frame standardized in the US. That is, the rear portion of the case projects rearward of the mounting frame, and is attached to the construction surface with the rear portion of the case inserted into the construction surface. In addition, a terminal for sending wiring is provided in order to send the signal line Ls between the operation terminals 82.

[0010]

In the above-mentioned conventional configuration, the signal lines Ls are sent and wired so that each operation terminal 8 is operated.
2 can be connected to the signal line Ls, but even if a plurality of operation terminals 82 are arranged in one place, a connection work between the operation terminals 82 is necessary. And there is a problem that wiring work becomes troublesome.
