Redundancy processing method, device and medium for nuclear power plant safety-level dcs optimal communication network

Abstract

The invention discloses a redundant processing method, device and medium for a preferred communication network of a safety-level DCS of a nuclear power plant, relates to the field of safety-level equipment of a nuclear power plant, and solves the problem that all redundant modules are directly connected to a main control module and affect the performance of the main control module. The present invention includes that the main control module and the optimal communication module both have a two-by-two structure, and the optimal communication module performs two out of two fault diagnosis information on the optimal communication network, and the main control module performs two out of two fault diagnosis information on the optimal communication module; preferably The communication module redundantly processes the data information of the lower-level module, and the lower-level module is a lower-level module of the preferred communication module; the main control module redundantly processes the preferred communication module. The invention can expand the system capacity, reduce the load of the main control module and give real-time fault alarm while ensuring that the system has no single fault.

Description

technical field [0001] The invention relates to the field of nuclear power plant safety level equipment, in particular to a redundancy processing method, device and medium for a nuclear power plant safety level DCS optimal communication network. Background technique [0002] Redundancy design technology, also known as redundancy design technology, is to add more than one set of the same functional channels, working elements or components where the system or equipment completes the task, so as to ensure that when the part fails, the system or The equipment can still work normally, so as to reduce the failure probability of the system or equipment and improve the reliability of the system. [0003] In order to ensure the reliability of safety-level equipment, the safety-level equipment of nuclear power plants based on microprocessors uses redundant design technology. However, the use of redundant technology means that the system becomes bloated and complicated, and redundant p...
