As shown in fig. 3, a block diagram of a debugging system for a nuclear power plant reactor head exhaust control cabinet provided by the invention includes the debugging device for a nuclear power plant reactor head exhaust control cabinet and further includes a control cabinet 140.
The control cabinet 140 is configured to send an action debug instruction, receive and display a position signal or a position fault signal, and perform logic processing on the position signal or the position fault signal to output a corresponding action debug result or a fault debug result to the signal module 130;

Further, the control cabinet 140 further includes a display module. The display module is used for acquiring and displaying a first open position state and a first close position state in the position signals, and acquiring and displaying a second open position state and a second close position state in the position fault signals.
Referring to fig. 1, 2 and 3, the debugging system for a nuclear power plant reactor roof exhaust control cabinet provided by the invention is further used for implementing the debugging method for the nuclear power plant reactor roof exhaust control cabinet, and specific embodiments of the debugging method are as follows:
the control cabinet 140 sends out an action debugging instruction, wherein the action debugging instruction is a 24V voltage signal, the voltage relay is electrified after receiving the voltage signal, and the action that the normally closed contact is closed and the normally open contact is opened is generated, so that a position signal is generated; after receiving the on/off position states in the position signal, the control cabinet 140 performs logic processing, outputs an action debugging result, and the signal module 130 receives and displays the action debugging result. If the signal module 130 is displayed as normal, the result of the logic processing of the normal position state of the on-site exhaust valve by the control cabinet 140 is correct; if the signal module 130 is abnormal, the result of the logic processing of the normal position state of the on-site exhaust valve by the control cabinet 140 is wrong, and the logic channel of the control cabinet needs to be refurbished and debugged.
The first button SB1 is pressed to trigger a fault debugging action, and since the button changes the switching value state of the output of the voltage relay, the voltage relay generates a first position fault signal at this time, the output on position state and the off position state are both output faults of the switching value 1, the control cabinet 140 receives the first position fault signal, performs logic processing and outputs a fault debugging result, and the signal module 130 receives and displays the fault debugging result. If the signal module 130 is displayed as normal, the result of the logic processing of the fault location state of the on-site exhaust valve by the control cabinet 140 is indicated as error; if the signal module 130 shows an abnormality, the result of the logic processing of the fault location status of the field exhaust valve by the control cabinet 140 is correct.
Similarly, when the second button SB2 is pressed to trigger the fault debugging action, the voltage relay generates a second position fault signal because the button changes the switching value state output by the voltage relay, and outputs an output fault of which the on position state and the off position state are both switching value 0, the control cabinet 140 receives the second position fault signal, performs logic processing and outputs a fault debugging result, and the signal module 130 receives and displays the fault debugging result. If the signal module 130 is displayed as normal, the result of the logic processing of the fault location state of the on-site exhaust valve by the control cabinet 140 is indicated as error; if the signal module 130 shows an abnormality, the result of the logic processing of the fault location status of the field exhaust valve by the control cabinet 140 is correct.
By implementing the debugging method, device and system for the nuclear power plant reactor top cover exhaust control cabinet, the signal generated by the on-site exhaust valve can be simulated to realize the logic channel test of the pressure vessel top cover exhaust control cabinet, the on-site disassembly line can be reduced, the risks of damage to the control cabinet and poor logic test effect caused by operation errors are reduced, and the system usable period is optimized.
