Embodiment Construction

[0019] Fig. 1 is a schematic diagram of the data sharing design scheme of the anti-mislocking function of the intelligent measurement and control device of the present invention, and Fig. 2 is a schematic diagram of the internal realization design scheme of the anti-mislocking function of the intelligent measurement and control device of the present invention. The invention will be specifically introduced below in conjunction with the accompanying drawings.

[0020] The anti-mistake locking logic in the present invention is realized by writing the expression logic text, and then downloading the logic text to the intelligent measurement and control device through the Ethernet using a special UDP communication protocol. The data sources involved in the logic operation in the logic expression may include the internal data of the device and the data of other external intelligent measurement and control devices. As shown in Figure 1, Figure 1 shows a schematic diagram of data sharin...

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...
