Abstract

PURPOSE:To omit the replacement of a memory part and to attain single touch operation, by preparing the memory part corresponding to a slave unit, storing the same program of the slave unit in the memory part and connecting the memory part to an internal bus so as to be interlocked with an alteration switch. CONSTITUTION:The same programs are stored in the memory parts B1-Bn in accordance with the slave units S1-Sn. An internal switch G connects the memory parts B1-Bn with the internal bus H and is interlocked with alteration switches SW1-SWn to execute the same information processing as the slave units. Accordingly at the failure of the slave units S1-Sn, a transmission line from a plate to be controlled at the time of maintenance and inspection is switched by turning the alteration switches SW1-SWn, so that the same programs B1-Bn are connected to the internal bus H automatically and backup operation is performed without trouble.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention provides a backup system for remote monitoring and control equipment, particularly when an information processing unit in a remote monitoring and control center corresponding to a plurality of controlled station devices becomes defective. The present invention relates to a remote monitoring and control device capable of processing.

[Technical disadvantage of invention]

FIG. 1 is a diagram showing the configuration of a conventional remote monitoring and control device. This remote monitoring and control device includes new controlled equipment #R8 to Rn that performs a process of transmitting monitoring and control information of monitored and controlled equipment, and a control center device M8 for the plurality of controlled equipment R1 to Rn.
It has A conventional control center apparatus Msf to which the present invention is applied will be described below with reference to FIG.

This control center device Ma is a main information processing unit (hereinafter referred to as the main unit) for finally processing the monitoring and control information.
and slave information processing units 81 to sn (hereinafter referred to as slave units) that perform information transmission with the controlled station devices R1 to Rn, and a pack for information transmission processing at the time of failure or maintenance inspection of the slave units 81 to Sn. It consists of a backup unit BK that performs backup.

The main unit ( ) M has an internal path between the microprocessor A, the memory section B, the input/output device E that performs input/output processing with external equipment in the control center, and the master/slave interface section C that exchanges information with the slave units 81 to Sn. I'm sick of connecting to H. Moreover, the main unit M mainly performs the exchange of monitoring and control information with control devices other than the control equipment [11M5] and interface processing with the slave units 81 to Sn.

On the other hand, slave unit S, ~5nFi each controlled station device R1~
Each of the slave units 81 to 81 has a different program, and these programs are stored in each memory section B in the slave units 81 to Sn. The structure of the slave unit is almost the same as that of the main unit M, and the input/output device E is a data converter. Here, the reason why the programs of slave units s and ~Sn are individually different is as follows.
This is because the amount of information of the monitored and controlled equipment in the controlled station and the transmission method used by the manufacturers of the controlled devices R3 to Rn often differ. In order to enable standard processing of the main unit) M, a plurality of slave units S, ~Sn
uses the Kuunit classification of master and slave.

[Problems with background technology]

In the event of a failure or maintenance inspection of the slave units S, ~Sn, the switching unit The corresponding changeover switch SW, ~S
Wn causes the transmission line J to be switched from the slave units S, ~Sn to the pack-up unit (BK) side. However, since the programs in the slave units 81 to Sn are individually different, when a particular slave unit is switched to the backup unit /)BK, the memory section B must be replaced or multiple Backup unit) By providing BK, it is necessary to perform backup processing using a circuit similar to the switching unit F.

In this way, the conventional pack-up unit) BKi-1:
When the p transmission path J is switched by the switches sw1 to SWn of the switching section F, the memory section of the processing contents of the corresponding slave unit is replaced, or multiple backup units)
connection is made.

For this reason, it is necessary to always have multiple memory units or multiple individual pickup units (BKs), resulting in higher prices, problems with mounting space due to the diversification of units, reduced maintainability, and the ability to easily utilize backup unit BKs. There were drawbacks such as not being able to do so.

[Purpose of the invention]

The present invention has been developed to solve the above-mentioned problems, and it is an object of the present invention to provide a remote monitoring and control device that can easily utilize a pick-up unit.

[Summary of the invention]

In the present invention, a plurality of memory sections are provided in the backup unit to store programs corresponding to the slave units, and the Z/Memory sections corresponding to the slave units are linked to the switch of the switching section.
It attempts to switch and connect programs each time.

[Embodiments of the invention]

Embodiments will be described below with reference to the drawings. FIG. 2 is an exemplary configuration diagram of a remote monitoring and control device according to the present invention.

In FIG. 2, only the configuration of Bx (Pa, Quag Unit) is different, and the rest is the same as the conventional line shown in FIG. 1.

Therefore, the symbols in the figure also correspond to those in FIG. B...
