BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating terminal for a remote monitoring control system used in a remote monitoring control system for monitoring and controlling a load and having a switch for operating the load.

[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 multiplex connection method, and operation data generated by operating a switch in an operation terminal equipped with a switch. There is provided a remote monitoring control system in which the control data is created based on the above, and the control data is transmitted to the control terminal device to which the load is connected so that the operating state of the load corresponds to the operation of the switch. .

A remote monitoring control system is shown in FIG. 25, for example.
It is configured as shown in. That is, the central processing unit 81

Individual addresses are set in the operation terminal 82 and the control terminal 83, and the central processing unit 81 uses the addresses to operate the operation terminal 82 and the control terminal 8 respectively.
Recognize 3 individually.

The central processing unit 81 uses the signal line Ls
A transmission signal Vs having a format as shown in FIGS. 26A and 26B is transmitted. That is, the transmission signal Vs is a start pulse ST indicating the start of signal transmission, a mode data signal MD indicating the signal mode, and an address data signal for transmitting address data for individually calling the operation terminal 82 and the control terminal 83. A time slot for receiving 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, and a return signal from the operation terminal 82 or the control terminal 83. Is a bipolar (± 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, when the address data transmitted by the transmission signal Vs received through the signal line Ls matches the preset address data, the transmission signal Vs The control data is taken in from and the return data is returned as a current mode signal (a signal sent 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 central processing unit 81 is provided with dummy signal transmitting means and 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 an empty address that is not set as the address data is constantly transmitted. Further, the interrupt signal processing means, when receiving the interrupt signal Vi generated by any of the operation terminals 82 as shown in FIG. 26C, after detecting the operation terminal 82 that generated the interrupt signal. , The operation terminal 82 is accessed to return the reply data. That is, the dummy signal transmitting means always sends the dummy signal to the signal line Ls, and the interrupt signal Vi generated from the operation terminal 82 in accordance with the operation of the switch SW is synchronized with the start pulse signal ST of the dummy transmission signal. When detected, the central processing unit 81 sends out the transmission signal Vs in which the mode data signal MD is set to the address confirmation mode 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 applied to each group. When the mode data signal MD receives the transmission signal Vs in the address confirmation mode, the operation terminal 82 that has generated the interrupt signal Vi is synchronized with the signal return period WT of the transmission signal Vs, and the operation terminal 8 is operated.
The address data set to 2 is returned as reply data. In this way, the central processing unit 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 to connect to the operation terminal device 82. The operation data corresponding to the operation state of the operated switch SW is received as reply data.

In the central processing unit 81, the operation terminal 82
Based on the operation data returned from the control data, the control data to be transmitted to the control terminal device 83 to which the load L having the corresponding relationship with the switch SW is connected is created, and the transmission signal Vs including the control data is generated. The load L is controlled by sending it to the signal line Ls and transmitting the control data to the corresponding control terminal device 83.

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

By the way, in the conventional operation terminal 82,
A synthetic resin molded product is used for the handle for operating the switch SW.

[0010]

As described above, if a synthetic resin molded product is used for the handle for operating the switch SW, it is difficult to obtain a high-class feeling and a heavy feeling.
That is, in intelligent buildings and luxury homes,
The handle of the switch SW is required to have a high-class feel and a heavy feel so as to be suitable for its appearance, but the handle of the synthetic resin molded product has a limit to meet such demand.
