Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display operation terminal unit of a remote monitoring control system.

[0002]

2. Description of the Related Art Conventionally, there is a remote monitoring control system for controlling and monitoring a load by using time division multiplex transmission. Figure 9
Shows an example of a conventional remote monitoring control system for remotely monitoring and controlling a lighting device. A plurality of load control terminals 3 and a wall are connected to a signal line 4 formed of a pair of lines connected to the transmission unit 1. A switch terminal 2 for operating and monitoring the operation switch 6 such as a switch, and a display panel in which a layout diagram corresponding to the layout of the load 5 are drawn, and the loads 5 arranged in the respective zone units A to D are provided. A system is configured by connecting a display operation terminal 7 having a plurality of switch terminals 2 having operation switches 6 that can be operated in zone units, and connecting a load 5 to a load control terminal 3. is doing.

The operation of the system will be described based on the multiplex transmission signal shown in FIG. 10. From the transmission unit 1, the multiplex transmission signal V having the format shown in FIG.
s is sent, and the load control terminal 3 and the switch terminal 2 are monitored and controlled. That is, the multiplex transmission signal Vs is the start pulse S indicating the start of signal transmission.
T, a multi-pole (mode data MD indicating a signal mode, address data AD, control data CD for controlling a load, checksum data CS for detecting a transmission error, and a signal reply period WT for setting a reply period of reply data ( ± 24
V) is a time division multiplex transmission signal, and data is transmitted by pulse width modulation.

Load control terminal 3 and switch terminal 2
Then, when the address data AD of the multiplex transmission signal Vs respectively received via the signal line 4 coincides with its own preset address, the control data CD of the multiplex transmission signal Vs is taken in and the multiplex transmission is performed. The reply signal is sent back as a current mode signal (a signal sent by short-circuiting the lines of the signal line 4 via an appropriate low impedance) in synchronization with the signal reply period WT of the signal Vs.

On the other hand, the transmission unit 1 is provided with dummy signal transmitting means and interrupt processing means. The dummy signal transmitting means constantly transmits the multiplex transmission signal Vs in which the mode data MD is in the dummy mode. Further, the interrupt processing means uses the interrupt signal Vi as shown in FIG.
Is sent back, the reply data is sent back from the switch terminal 2 that generated the interrupt signal Vi. That is, the switch terminal 2 connects the switch output of the operation switch 6, and this switch output is turned on,
Alternatively, when it is turned off, the interrupt signal Vi is sent according to the change of the switch input. The transmission unit 1 transmits a multiplex transmission signal Vs for address search for each group address in order to search the interrupted terminal device 2 in response to the interrupt signal Vi. The interrupting switch terminal 2 returns its own unique address as reply data when the group to which it belongs is accessed.

By this reply, the transmission unit 1 judges the interrupting switch terminal 2, and then transmits the multiplex transmission signal Vs having the address data AD of the switch terminal 2 for the switch. The terminal device 2 is accessed and the operation data of the operation switch 6 connected from the switch terminal device 2 is returned as reply data.

Based on the operation data returned from the switch terminal 2, the transmission unit 1 controls the load control terminal 3 that controls the load 5 corresponding to the switch terminal 2. While creating a data CD,
The multiplex transmission signal Vs including the control data CD is sent to the signal line 4
Each load 5 is individually turned on / off by performing time division multiplex transmission to the load control terminal 3 via the.

In the transmission unit 1, the switch terminal 2
Correspondence is set between the switch terminal 2 and the load control terminal 3 to which the load 5 to be controlled is connected in response to the operation data returned from the load control terminal according to this correspondence. The load 5 of the container 3 is on / off controlled. By the way, as shown in FIG. 11, the display operation terminal 7 includes a mounting frame 8 attached to the front opening of the terminal body 7A, and a plate surrounding the mounting frame 8 to which the mounting frame 8 is attached. A frame 9, a layout sheet 10 arranged on the surface of the mounting frame 8, a plate 11 for sandwiching and fixing the layout sheet 10 with the plate frame 9, and mounting holes 12 formed in the mounting frame 8 vertically and horizontally. And a blank chip 13 that is inserted into the mounting hole 12 where the switching terminal 2 is not inserted and closes the mounting hole 12.
A layout diagram corresponding to the layout of the load 5 is printed on the layout sheet 10.
The switch terminal 2 corresponding to the load 5 arranged in the zones A to D shown in FIG. 9 in this layout diagram is inserted into the mounting holes 12 corresponding to the positions of the zones A to D on the layout diagram, The operation switch 6 provided on the front surface of the switch terminal 2 can be pushed from the front side of the layout sheet 10.

The switch terminal 2 used for the display operation terminal 7 is formed in a rectangular parallelepiped shape as shown in FIG. 12, and a side surface is provided with a DIP switch operation portion 14 for setting an address and a type, and a front surface. The operation part of the operation switch 6 composed of a built-in push button switch is exposed. By using the display operation terminal device 7 described above, the load 5 arranged in a desired zone can be turned on / off simply by operating the operation switch 6 arranged corresponding to the zones A to D on the layout diagram of the layout sheet 10. Because you can
There is an advantage that operability is improved.

[0010]

However, when the layout of the load 7 is changed in the display operation terminal unit 7 described above, it is necessary to replace the layout sheet 10 corresponding to the changed layout, and the switching terminal unit 2 Since it is also necessary to change the movement of the insertion position, the display operation terminal device 7 has to be disassembled once, which is troublesome.

In particular, since the layout sheet 10 is usually printed by silk-screening the layout diagram, the layout sheet 10
There was a problem that it took time and effort to change. Further, when it is necessary to change the address or type of the switch terminal 2 due to the layout change, it is necessary to remove the switch terminal 2 from the mounting frame 8 and set the DIP switch. There was a problem that it took time.

Further, even when the switch terminal 2 is added by changing the layout, it is necessary to disassemble the display operation terminal 7 and insert and connect the switch terminal 2 to be added. There was a problem that it took time and effort.
