Nuclear power plant priority management system

Abstract

The embodiment of the invention provides a nuclear power plant priority management system comprising a priority management device connected with a hard-wired interface and a security-level instruction interface. The priority management device is also connected with a non-security-level communication interface through the hard-wired interface; and the non-security-level communication interface is used for realizing connection with a non-security-level system and receiving a non-security-level equipment-level control instruction from the non-security-level system. The nuclear power plant priority management system is integrated with the hard-wired interface, the security-level instruction interface, and the non-security-level communication interface and thus can receive control instructions all security-level systems conveniently, so that the engineering applicability is high. Moreover, on the basis of direct connection of the non-security-level communication interface with the non-security-level system, connection of lots of hard wiring can be avoided, so that usability of the system in terms of project implementation can be improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant safety control, in particular to a nuclear power plant, especially a priority management system for non-safety systems. Background technique [0002] The priority management system is an interface management device between the digital instrument and control system of the nuclear power plant and other systems and field equipment. It is mainly used for priority management of the instructions sent by each system or equipment to ensure the safe operation of the nuclear power plant. The existing priority management system has strong customization characteristics and low applicability for engineering implementation. Usually, the priority management system only has hard-wired interfaces, or the communication interface only supports security-level communication interfaces, or the communication interface only supports non-safety communication interfaces. level communication interface, resulting...

Problems solved by technology

[0004] Among them, especially when the priority management system is connected to equipment-level manual control commands from non-safety systems, a large number of hard-wired connections are connected to non-safety-level factory buildings and safety-level factory buildings, and the distance and quantity of hardwired lines are long. , Occupy the cabinet space, resulting in extremely inconvenient project implementation
