Error lock-proof function design scheme for intelligent measuring and control device

Abstract

This invention relates a kind of preventing false deadlock function design method of the intellect detect and control device. It is characterized in that it can realizes the fully-automatic sweep, semi-automatic sweep, remote and trigger multiple flexible configurations mode of operation by programming the preventing false deadlock logic; the intellect detect and control device can realize the data sharing by the network and every device offers six hard deadlock junction outputs and realize the software preventing false add hardware preventing false truly; the design method concludes eleven sub function blocks: semi-automatic scan mode of operation module, hard deadlock junction control module, remote control trigger mode of operation module, logic calculation service interface module, full-automatic scan mode of operation module, this device real time data base module, logic calculation real time data base module, GOOSE communication service module, signal acquisition unit module, UDP communication service module, Ethernet interface module. This invention can make up for the shortage of traditional preventing false deadlock and reduce the line connection of the secondary circuit and simplify the construction and can run independently and enhance the safe reliability of the systems operation.

Description

technical field [0001] The invention relates to an anti-mislocking function technology of an electric power system, in particular to an anti-mislocking function technology of an intelligent measurement and control device. The utility model belongs to the technical field of electric power automation. Background technique [0002] In the automatic measurement and control process of substations, switching stations, power plants, metallurgy, and chemical industries, in order to prevent misoperations, the automation system is required to have the anti-misoperation locking function. False locking. Electrical misoperation prevention is a kind of anti-misoperation function based on the secondary operation circuit. It is generally realized by connecting auxiliary contacts of circuit breakers and switches in series on the secondary operation circuit and interlocking with each other. However, the wiring of the secondary circuit is complicated. In addition, the insulation damage of th...

AI Technical Summary

Problems solved by technology

The traditional electrical anti-misoperation locking method can no longer meet the requirements, and the microcomputer anti-misoperation locking system, which is the development direction of the comprehensive automation application of substations, needs to be further improved and improved in terms of functions.
