Nuclear power plant nuclear power trigger shutdown control system

The invention discloses a nuclear power plant nuclear power trigger shutdown control system. The control system comprises a field signal acquisition module, a control panel module, a first channel control module, a second channel signal output module and a power supply module. Wherein the first channel control module comprises a plurality of switching value input units DI, an analog quantity input unit AI, a switching value output unit DO, a processor MPU and a communication unit; the MPU is used for performing logical operation on the sensor signal, the input signal sent by the control panel module, the output signal of the second channel signal output module and the blocking signal to generate a logical operation result; and the switching value output unit DO is used for outputting a logical operation result and triggering a first channel intermediate range nuclear power high shutdown protection signal. The control system can reduce the mistaken touch risk of the reactor shutdown protection signal triggered
