DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing the configuration of a supervisory control system. FIG. 2 is a conceptual diagram illustrating group setting data stored in the group setting transmission unit.

In FIG. 1, the same parts as those of the supervisory control system described in the above-mentioned prior art are designated by the same reference numerals, and a detailed description of the same parts will be omitted.

The supervisory control system of this embodiment shown in FIG. 1 is different from the supervisory control system described in the above-mentioned prior art in that it has the following features.

That is, first, the main controller 3d of the management device 3
Specifies the data format of the status data request signal or control signal to be transmitted to "destination: XX (group) command: XX
It has a configuration of "XXXX" and is transmitted by broadcast. That is, in the data format described in the related art, the monitoring control device 2 is designated as the "destination", but the "destination" is designated by the "group". The group represents a set of the monitoring control devices 2, and the monitoring control device 2 can belong to a plurality of groups.

Secondly, the supervisory control device 2 is provided with a group setting storage section 2e and a determination section 2f.

The group setting storage unit 2e is composed of a memory, and stores the group setting data received by the transmitting / receiving unit 2a from the group setting transmitting unit 3e described later through the transmitting / receiving unit 3a. The group setting data is, for each monitoring control device 2, data indicating which group the monitoring control device belongs to.
become that way. In FIG. 2, for example, the monitoring control device 2
A indicates that it belongs to groups 1, 3, 6, 9 and monitor control apparatus B belongs to groups 2, 3, 6, 8, and 9.

The determination unit 2f sends a message "Transmission destination:
XX (group) command: whether or not the own monitoring controller 2 belongs to the group "XX" of the "destination" indicated by the status data request signal or the control signal transmitted by the broadcast in the form of "XXXXXX" Group setting storage unit 2
The judgment is made by comparing with the group setting data stored in e.
If the determination unit 2f belongs to the "destination" group "XX", the determination unit 2f reads the status data from the buffer and outputs the status data to the transmission / reception unit 2a, or outputs the control signal to the control unit 2d.

Thirdly, the management device 3 is provided with a group setting transmission section 6. Group setting transmission unit 6
Is for outputting predetermined group setting data to the transmitting / receiving unit 3a when the supervisory control system is activated or when the settings are changed.

The operation of the supervisory control system configured as above will be described. It is assumed that ten supervisory control devices 2 A to J are provided in the supervisory control system. Further, the group to which each monitoring control device 2 belongs is as shown in FIG.

First, in the supervisory control system, the management apparatus 3 transmits the group setting data shown in FIG. 2 to each supervisory controller 2, and when each supervisory controller 2 receives the group setting data, the group setting data is stored. Group setting data is stored in the unit 2e. For example, the monitoring control device 2A receives the group setting data of "1, 3, 6, 9",
It is stored in the group setting storage unit 2e.

Next, during operation of the system, the management device 3 causes the supervisory control devices 2A, 2C, 2E, 2G, 2I, 2 to operate.
When transmitting a control signal to J, the main control unit 3
d transmits a control signal having the content of "transmission destination: group 1 command: control" to all the monitoring control devices 2 once by broadcast.

The transmitting / receiving sections 2a of all the monitoring control devices 2 are
The control signal is received and output to the determination unit 2f. Judgment unit 2
f determines whether or not its own monitoring control device 2 belongs to the "destination" group "1" of the signal, and its own monitoring control device 2 belongs to the "destination" group "1". If so, the control signal is output to the control unit 2d. For example, since the monitoring control device 2A belongs to the group “1”, the determination unit 2f outputs the control signal to the control unit 2d, and the load device 4
Will be controlled. On the other hand, in the case of the monitor control device 2 that does not belong to the group “1” such as the monitor control device 2B, the determination unit 2f ends the process without outputting the control signal to the control unit 2d and waits for the next signal. .

As described above, when the management device 3 transmits the control signal or the status data request signal once by broadcast, the supervisory control devices 2 belonging to the group designated as the destination of the signal are controlled. A signal or status data request signal can be received.

In this embodiment, the monitoring control device 2 is set to 1
Although the number of units is 0, the number of units is not limited to 10, and a plurality of units may be used.

Further, in the present embodiment, the transmission of the signal from the management device 3 to the monitoring control device 2 is changed from "destination" to "group".
However, it may be used together with the method of directly transmitting the "destination" as the monitoring control device 2 as described in the conventional technique.

[0042]

Since the monitoring control method and the system thereof according to the present invention are configured as described above, in the invention according to claim 1, the management device assigns a group to which one or more monitoring control devices belong. A signal is sent as a destination, and the supervisory control device performs the monitoring or control indicated by the signal only when it belongs to the group of the signal received from the management device. Therefore, the group is designated as the destination. When broadcast, all supervisory control devices receive signals,
Since only the supervisory control device belonging to the group performs the monitoring or control indicated by the signal, it is possible to reduce the communication amount between the supervisory control device and the management device and reduce the load of transmission / reception processing of the supervisory control system. The effect of providing a supervisory control method is produced.

According to another aspect of the present invention, the main control unit of the management device sends a signal to the group to which one or more supervisory control devices belong as a transmission destination, and the group setting storage unit of the supervisory control device is self-serving. Of the signal received from the management device, based on the stored contents of the group setting storage unit, the determination unit determines whether or not it belongs to the group, and accordingly specifies the group as the transmission destination. When the broadcast is performed by the broadcast, all the monitoring control devices receive the signal, but only the monitoring control devices belonging to the group perform the monitoring or control indicated by the signal, so that the communication between the monitoring control device and the management device is performed. The effect is to provide a monitoring control system that can reduce the amount and reduce the load of transmission / reception processing of the monitoring control system.

According to the invention of claim 3, claim 2
In addition to the effects of the described invention, the group setting transmission unit of the management device sends group setting data designating which group the monitoring control device belongs to, to the group setting storage of the monitoring control device. Since the section receives and stores the group setting data, it is possible to change the group to which the supervisory control device belongs from the management device side, and it is not necessary to visit the installation location of the supervisory control device one by one, thus changing the transmission destination of the signal. The present invention has the effect of providing a supervisory control system in which the system can be easily changed when performing.
