Control right management system and method for backup panel of main control room of nuclear power plant

Abstract

The invention belongs to the field of nuclear power plant control right management, and particularly relates to a control right management system and method for a backup panel of main control room of a nuclear power plant, and the system comprises a release function module, a logic processing module, a DCS cabinet module, and a computerized workstation exit information prompt module. The release function module, the logic processing module and the DCS cabinet module are connected in sequence, and the DCS cabinet module is respectively connected with the release function module and the computerized workstation quit information prompting module. According to the invention, the problems of failure of switching signal and inter-cabinet interlocking signal transmission caused by DCS network failure, simultaneous failure of partial functions of a backup panel in a main control room and a computerized workstation, loss of related process system equipment control functions caused by switching switch failure and the like are solved, and the authority management logic is simplified; the construction difficulty caused by the fact that all control signals are achieved in a hard wiring mode is solved, and the engineering design and implementation cost is saved.

Description

technical field [0001] The invention belongs to the management field of control rights of nuclear power plants, and in particular relates to a management system and method for backup disk control rights of a main control room of a nuclear power plant. Background technique [0002] With the continuous development of digital technology, the main control rooms of nuclear power plants at home and abroad have adopted computerized workstations as the main human-machine interface equipment for the operators to realize the monitoring function of the power plant. However, even if the computer has a high degree of reliability, it still needs Considering the situation of its failure, the method of controlling the management function is particularly important while introducing diversified monitoring methods. In a pressurized water reactor nuclear power project, in order to cope with the failure of computerized workstations, backup disks mainly using conventional monitoring equipment swi...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a backup disk control right management system and method in the main control room of a nuclear power plant to solve the problem of switching signals and interlocking signal transmission failures between cabinets caused by the failure of the DCS network, causing some functions of the backup disk in the main control room to be synchronized with computerized workstations. Problems such as loss of control functions of related process system equipment caused by failure and switch failure, while simplifying the authority management logic, solve the construction difficulties caused by the realization of all control signals by hard wiring, saving engineering design and implementation costs
