Problems solved by technology

[0002] At present, nuclear power plants have many process systems and complex equipment. During the operation of the equipment, the equipment often stops running due to the failure of the system or the equipment itself.
When the equipment fails, operation and maintenance professionals need to spend a lot of time to check the cause of the failure. The cause of the failure cannot be diagnosed automatically and quickly, which seriously affects the operation and recovery of the equipment.

Abstract

The invention discloses a nuclear power station device and a fault diagnosis method. The nuclear power station comprises steps of obtaining a first emission signal when a device is faulted, wherein the first emission signal is a first alarm signal which is outputted when the device is faulted, inputting the obtained first emission signal into logic configuration to perform corresponding logic operation, outputting a logic operation result, and determining the kind of the first emission signal according to the logic operation result. When the nuclear power station device is faulted, the invention can automatically and fast diagnose the reason of the fault and fast recover the operation of the device.
