Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display operation panel 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. As shown in FIG. 6, this remote monitoring control system monitors the operation of a plurality of load control terminals 3 and an operation switch 6 such as a wall switch on a transmission line 4 consisting of a pair of lines connected to a control device 1. An operation switch 6 having a switch terminal 2 for performing the operation, a display panel on which a layout diagram corresponding to the layout of the load 5 is drawn, and which can operate the load 5 arranged in each zone unit A to D in each zone. Are connected to a display operation panel 7 having a plurality of switch terminals 2 ..., And a load 5 is connected to the load control terminal 3 to form a system.

The operation of the system will be described with reference to the multiplex transmission signal shown in FIG.
The multiplex transmission signal Vs having the format shown in FIG. 9A is sent out, and the load control terminal device 3 and the switch terminal device 2 are monitored and controlled. That is, the multiplex transmission signal V
s is a start pulse ST indicating the start of signal transmission, mode data MD indicating the signal mode, and address data A
D, a control data CD for controlling the load, a checksum data CS for detecting a transmission error, and a signal return period WT for setting a return period of the return data, which is a bipolar (± 24V) time division multiplex transmission signal, and is a pulse. Data is adapted to be transmitted by width modulation.

Load control terminal 3 and switch terminal 2
Then, when the address data AD of the multiplex transmission signal Vs respectively received through the transmission 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 transmission line 4 via an appropriate low impedance) in synchronization with the signal reply period WT of the signal Vs.

On the other hand, the control device 1 is provided with a dummy signal transmitting means and an 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, when the interrupt signal Vi as shown in FIG. 7 (b) is returned, the interrupt processing means causes the switch terminal 2 which generated the interrupt signal Vi to return the reply data. That is, the switch terminal 2 is connected to the switch output of the operation switch 6, and when the switch output is turned on or off, the interrupt signal Vi is transmitted according to the change of the switch input. In the control device 1,
Corresponding to the interrupt signal Vi, a multiplex transmission signal Vs for address search is transmitted for each group address in order to search the interrupted terminal 2. 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 control device 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 to transmit the switch signal. Access terminal 2,
Operation switch 6 connected from the switch terminal 2
The operation data of is returned as reply data.

Based on the operation data returned from the switch terminal device 2 as described above, the control device 1 controls the load control terminal device 3 for controlling the load 5 corresponding to the switch terminal device 2. The data CD is created and the multiplex transmission signal Vs including the control data CD is time-divisionally multiplexed and transmitted to the load control terminal 3 via the transmission line 4, whereby the loads 5 are individually turned on and off. It is like this.

In the control device 1, in response to the operation data returned from the switch terminal device 2, the load control terminal device 3 in which the switch terminal device 2 and the load 5 to be controlled are connected.
Has been set, and the load 5 of the load control terminal device 3 is controlled to be turned on and off according to this correspondence. By the way, as shown in FIG. 8, the display operation panel 7 includes a mounting frame 8 attached to the front opening of the panel body 7A, and a plate frame 9 surrounding the mounting frame 8 to which the mounting frame 8 is attached. When,
A layout sheet 10 arranged on the surface of the mounting frame 8;
A plate 11 for fixing the layout sheet 10 by sandwiching it with the plate frame 9, a switch terminal 2 to be inserted into a mounting hole 12 formed in the mounting frame 8 vertically and horizontally, and a switch terminal 2 are inserted. It is composed of a blank chip 13 and the like that is inserted into the mounting hole 12 that is not mounted and closes the mounting hole 12. A layout diagram corresponding to the layout of the load 5 is printed on the layout sheet 10, and the layout diagram is shown in FIG. The switch terminals 2 corresponding to the loads 5 arranged in the zones A to D as shown by 6 are inserted into the mounting holes 12 corresponding to the positions of the zones A to D on the layout diagram, and the switch terminals 2 are attached. The operation switch 6 provided on the front surface of the layout sheet 10 can be pushed and operated from the front side of the layout sheet 10.

The switch terminal 2 used for the display / operation panel 7 is formed in a rectangular parallelepiped shape as shown in FIG. 9, a side face is provided with a DIP switch operation portion 14 for setting an address and a type, and a front face is provided. Has an operation portion of an operation switch 6 which is a built-in push button switch exposed. If the display operation panel 7 described above is used, the load 5 arranged in a desired zone can be turned on / off simply by operating the operation switches 6 arranged corresponding to the zones A to D on the layout diagram of the layout sheet 10. Therefore, there is an advantage that operability is improved.

However, when the layout of the load 7 is changed in the display operation panel 7 described above, it is necessary to replace it with the layout sheet 10 corresponding to the changed layout, and the movement of the insertion position of the switch terminal 2 is also changed. Since it is necessary, the display operation panel 7 has to be disassembled once, which is troublesome. Especially layout sheet 10
Since the layout diagram is usually silk-printed, there is a problem that it takes time and effort to change the layout sheet 10.

Further, when it is necessary to change the address and 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, which also takes a lot of time and labor. In addition, even when the switch terminal 2 is added by changing the layout, it is necessary to disassemble the display operation panel 7 and to insert and connect the switch terminal 2 to be added. In this case, time and labor are required. There was a problem of this.

Therefore, the load layout can be displayed on the liquid crystal display, the load can be controlled by the touch keys, and the positions of the screen and the touch keys can be changed, and the function of the switch and the addition of the switch can be easily added. The present inventors have proposed.

[0013]

However, in the display operation panel using the above-mentioned liquid crystal display and touch keys, since various settings are made by key operation, there are the following problems.
That is, in this type of remote monitoring control system, when the address setting and the type setting of the switch terminal 2 and the like are performed, the data setting device 28 for transmitting the address setting data and the type data by the optical wireless signal as shown in FIG. I am using. However, even if a display operation panel that is highly functional as described above and that is set by key operation is provided, the construction and setting are different from the conventional method, so the builder needs to learn a new usage method, Therefore, construction troubles are likely to occur and the construction may take time.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a display operation panel of a remote monitoring control system in which setting operation can be easily performed.

[0015]

In order to achieve the above-mentioned object, the present invention connects a control device, a plurality of switch terminals and a load control terminal via a pair of transmission lines,
The control device transmits the multiplex transmission signal to access the terminal device, and the load control terminal device is provided with the load control data based on the operation data of the operation switch connected to the corresponding switch terminal device. It is used in a remote monitoring control system that sends the operation data of the connected operation switches to the control device as monitoring data during the reply waiting period provided in the multiplex transmission signal. A display that displays a screen, an operation switch that consists of touch keys corresponding to the load on the displayed layout diagram, and a terminal function that returns the operation data of the operation switch to the control device as monitoring information for controlling the corresponding load. And the drawing function that creates screen data for the display and the position of the operation switch on the screen. And a receiving unit for receiving the optical wireless signal from the data setting unit for transmitting the address setting data and the type data of the terminal by the optical wireless signal, and the address of the terminal functional unit based on the received data. , Means for rewriting the type.

[0016]

According to the structure of the present invention, the screen data to be displayed on the display can be created by using the drawing function means. Therefore, even if the load layout is changed, only the screen data can be created and changed. Therefore, it is possible to deal with the situation more easily and quickly than when using a layout sheet on which a layout diagram is printed.

Further, when the layout of the load is changed, the address and type of the corresponding terminal functional means can be rewritten by using the data setting device, so that the operator can perform the setting changing operation that he or she has been accustomed to, and thus the construction trouble occurs. And the construction time is shortened.
