The invention discloses a test device and a test method for logic verification of a nuclear power station fire compartment. The nuclear power station fire compartment comprises: numerous detector information is collected by a mainboard module in a fire alarm controller in real time and is processed into information data, the information data is transmitted to a programmable controller, the programmable controller performs logical operation on the information data and generates signal data, and the signal data is transmitted to a digital control system to generate control action. The test device comprises a hardware part and a software part. The hardware part comprises a communication module, a processing module, a power supply module and a human-computer interface. The software part comprises data driver software positioned in the processing module, test textile data, a human-computer interface function and correct logical information, wherein the human-computer interface function comprises a function of realizing communication connection between the human-computer interface and the processing module, providing and completing export and import of data and report forms as well as anabnormal alarm function. The problem that the logic verification of the nuclear power station fire compartment is incomplete can be solved.
Description
technical field [0001] The invention relates to the field of fire detection of a fire protection system, in particular to a test device and a test method for logic verification of a fire zone (SFZ) of a nuclear power plant. Background technique [0002] The safety-related systems and equipment periodic test supervision program in nuclear power plants requires that all detectors in the safety protection area be tested for fire alarm channels in each refueling cycle, and the TO button on the analog panel needs to be verified, the purpose of which is to ensure that linkage is available in the event of a fire . There are a total of 2576 detection points for the 2 units of the nuclear island, and there are more than 320 linkage signals (SJ) and alarm signals (SJ. Its logic function is realized in the middle of the programmable logic controller (PLC), not relying on the simple linkage function of the fire alarm controller itself. As the main PLC that realizes the logic function,...
