Abstract

PURPOSE:To automatically select and control plural slave stations from a master station only through one operation by providing the master station with a memory means that groups the slave stations and stores them. CONSTITUTION:A memory device 12 in the master station 1 groups the slave stations 2-1-2-n and stores them. Namely, said equipment arbitrarily sets the number of groups of slave stations to which an operator wants to automatically select and control in the following format: the number of processed stations/ station (a)/station (b).../station (n). Consequently, by controlling the set data, all the groups of slave stations can be automatically selected and controlled only through one operation. Thus operation time can be shortened, and operational errors can be prevented.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Object of the Invention] (Field of Industrial Application) The present invention relates to a remote monitoring and control device, particularly a system for monitoring and controlling a remote monitoring and control device from a control center (hereinafter referred to as a master station) to a plurality of controlled stations. The present invention relates to a remote monitoring and control device that monitors and controls a slave station (hereinafter referred to as a slave station).

(Prior Art) FIG. 5 is a side view of a general configuration of a remote monitoring and control system, in which a master station 1 and a plurality of slave stations 2-1 to 2-n are connected via a transmission line 3. . From master station 1 to each slave station 2-1 to 2-n
The supervisory control data is transferred in the order shown in FIG. These series of operations are performed in the seventh
This will be explained using the flowchart shown in the figure.

First, as shown in step 71, the master station 1 communicates with the slave station 2.
The monitoring request data is sequentially transferred from -1 to the final slave station 2-n. In this case, if the monitoring request is transferred to the slave station 2-1, display data will be transferred as a response from the corresponding slave station 2-1, and after receiving this display data, the next slave station 2-2 will be sent to the next slave station 2-2. Transfer monitoring request data to
As in the case described above, the display data is transferred from the corresponding slave station 2-2, and this operation is repeated until the final slave station 2-n. That is, steps 71-72-75 are repeated until control data exists in step 72. When the control data of the slave station 2-m is input in step 72, the process moves to step 73, where the monitoring request processing up to that point is stopped and the process moves to selection control processing. That is, it recognizes the selected slave station layer, transfers the monitoring information 11'' to the slave station, receives display data from the slave station, and confirms that the slave station to be controlled has been selected. Then, in step 74, the control data is transferred to the corresponding slave station, and then in step 75, the monitoring request is sequentially transferred to the remaining slave stations.
After that, the process returns to step 71 and the above operations are repeated.

(Problems to be Solved by the Invention) In the conventional system described above, a control mode is inserted between monitoring modes, and one selection control operation is always required for the slave station 1 to be controlled. By the way, during periods such as thunderstorms, it is necessary to operate a large number of slave stations in a short period of time, but the operation of each slave station as described above requires multiple operations, and there is a possibility that operational errors may occur. It's large.

The present invention has been made to solve the above problems, and has the ability to automatically select and control a plurality of slave stations from a master station with a single operation, and has individual monitoring/selection control functions. The aim is to provide a remote monitoring and control device that is indispensable.

[Structure of the invention]

(Means for Solving the Problems) The configuration for achieving the above object will be explained with reference to FIG. 1 corresponding to the embodiment. Storage device 12 that stores data separately
The system was configured to provide the following.

(Operation) Therefore, when a specific slave station is selected by the transmission command means, each slave station in the group in which the slave station is included is automatically selected in sequence.

(Example) An example will be described below with reference to the drawings. FIG. 1 is a functional block diagram of an embodiment of a remote monitoring and control device according to the present invention.

In FIG. 1, 11 is a transmission command means, and 12 is a storage device which stores all slave stations in groups.

That is, the groups of slave stations for which you want to automatically perform selection control are stored in advance on the storage device of the master station as number of stations to be processed/station a/station b~/
An arbitrary number is set in the frame of station n. Therefore, depending on the control of the set data, 1
Automatically selects and controls all slave stations in a given group in a single operation.

13 is a transmission device.

FIG. 2 is a diagram showing a procedure for transferring supervisory control data, and the procedure for transmitting a supervisory request from the master station 1 to each of the slave stations 2-1 to 2-n is the same as in the conventional example.

The difference between the present invention and the prior art is that the station P
After the selection control process is completed, the process does not proceed to the monitoring request process.
This is the part in which the selection control process for the station Q is continued and the monitoring request process is started only after the selection control process for the final station is completed.

This will be explained using the flowchart shown in FIG.

In FIG. 3, steps 71 to 74 are the same as in the conventional example. That is, the master station 1 transfers the IK monitoring request to the slave station 2, and the slave station 2-1 that receives this transfers the display data as a response to the master station 1, and then sequentially transfers the display data to the slave station 2-1. 2. Repeat steps 2-3 and these operations up to the final slave station. If there is control data in step 72, proceed to step 73, confirm the selected slave station layer, and send the data to the corresponding slave station. The monitoring request is transferred, display data is received from the corresponding slave station, and it is confirmed that the slave station to be controlled has been selected, and the corresponding slave station control data is transferred in step 74. Next, in step 31, it is checked whether the selection control process for all registered slave stations has been completed, and if it has not been completed, the process returns to step 73 and the selection control process for the next registered slave station is performed. Thereafter, this operation is repeated sequentially until all registered slave stations are processed. When the processing has been completed for all slave stations, the process returns from step 75 to step 71 and repeats the above operations, as in the prior art. Therefore, the operator can perform selection control processing for a desired slave station group with a single operation.

FIG. 4 is a flowchart focusing only on the process for determining whether all slave station processing has been completed. The process of completing all slave station processing will be described below.

First, in step 41 at the start, the value of the processing counter is set to "1". In step 42, station data corresponding to the processing counter is extracted from stations a to n from a control table set in advance in the master station memory. Next, in step 73174, the same selection control process as described above is performed, and in step 43, "l" is added to the value of the processing station counter. Compare the value of the processing station counter stored on the Stellar F44 control table with the value of the processing station counter, and continue in steps 42 and 73 until they match.
, 74, 43, and 44 are repeated in sequence to complete the processing of all slave stations. Furthermore, by providing a plurality of control tables, selection control can be automatically performed for many types of groups.

〔Effect of the invention〕

As explained above, according to the present invention, slave stations for which selection control is to be performed automatically are divided into groups and set in the memory of the master station, and by controlling the set data, a single operation is performed. Since the configuration is configured to selectively control all of the slave stations in an arbitrary group, it is possible to automatically control all the slave stations in an arbitrary group, thereby making it possible to shorten operation time and prevent operational errors.
