Abstract

The invention discloses a transmission station for a security level instrument control system of a nuclear power plant. The transmission station is positioned among information transmission links of the security level instrument control system, and the security level instrument control system comprises an onsite control station, a security display station, an emergency control panel / backup panel, an engineer station and a gateway station. The transmission station is simultaneously connected with the onsite control station, the security display station, the emergency control panel / backup panel, the engineer station and the gateway station. The transmission station is used for executing collection and processing of fault diagnosis information of the security level instrument control system and further used for executing information exchange with the onsite control station and information exchange with the engineer station.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a transmission station used for a safety-level instrument and control system of a nuclear power plant. Background technique [0002] The nuclear power plant safety-level instrumentation and control system provides protection means and monitoring information for the nuclear power plant reactor to ensure the safe operation of the nuclear power plant under all normal, abnormal and accident conditions. Safety-level I&C systems are usually designed with redundant protection groups and logic series. In addition to handling emergency shutdown and special safety device drive functions, the protection group and logic series also need to undertake the collection and processing of fault diagnosis information, and control Information exchange in the office and information interaction with the maintenance engineer station. [0003] The above-mentioned design scheme makes the functions ...
