Embodiment 1

[0042] Such as figure 1 As shown, Embodiment 1 of the present invention provides a nuclear power plant relay logic processing cabinet test device, which is used to conduct regular tests on the relay logic of the relay logic processing cabinet 3, including an operation terminal 1 and a main controller 2 connected to each other. The operation terminal 1 is used to send a logic test instruction for testing the relay logic to the main controller 2, and the main controller 2 is used to receive the test instruction, and the test device also includes The isolation module 4 and the signal receiving and output module 5 between the main controller 2 and the relay logic processing cabinet 3; the main controller 2 is also used to send an isolation command to the isolation module 4 according to the logic test instruction And send a signal input command to the signal input receiving module 5; the isolation module 4 is used to isolate the signal connection between the relay logic processing ...

Embodiment 2

[0055] Such as Figure 4 As shown, Embodiment 2 of the present invention provides a test method for a nuclear power plant relay logic processing cabinet, which is characterized in that it includes the following steps:

[0056] S1. The operation terminal 1 sends a logic test instruction to the main controller 2 to test the relay logic;

[0057] S2. The main controller 2 sends an isolation command to the isolation module 4 and a signal input command to the signal input receiving module 5 according to the logic test instruction;

[0058] S3. The isolation module 4 isolates the signal connection between the relay logic processing cabinet 3 and the nuclear power system according to the isolation command;

[0059] S4. The signal receiving and output module 5 sends a relay logic test signal to the signal input end of the relay logic processing cabinet 3 according to the signal input command, and receives the relay logic output of the signal output end of the relay logic processing c...

Embodiment 3

[0063] Such as Figure 5 As shown, in the third embodiment of the present invention, the operation terminal 1 is also used to issue a system self-test instruction, a data backup instruction and a system recovery instruction to the main controller 2 .

[0064] In order to confirm that there is no connection error and that the communication is normal, steps are also included before step S1:

[0065]S01, the operation terminal 1 sends a system self-inspection instruction to the main controller 2, and the main controller 2 checks the operation terminal 1, the main controller 2, and the relay logic processing cabinet 3 when receiving the system self-inspection instruction , the isolation module 4 and the connection between the signal receiving and output module 5 to ensure that the device is connected properly.

[0066] In order not to affect the normal maintenance of the interface equipment of the relay logic processing cabinet during the test, and keep the state of the equipment...

Abstract

The invention discloses a nuclear power plant relay logic-processing cabinet testing device which comprises an operating terminal and a master controller. The operating terminal and the master controller are connected. The device also comprises an isolation module and a signal receiving and output module which are parallelly connected between the master controller and a relay logic-processing cabinet. The master controller is used for sending an isolation command to the isolation module and sending a signa input command to a signal input and receiving module. The isolation module is used for isolating the signal connection between the relay logic-processing cabinet and a nuclear power system according to the isolation command. The signal receiving and output module is used for sending a relay logic testing signal to the signal input end of the relay logic-processing cabinet and receiving a relay logic output signal from the output end. In addition, the invention also provides a nuclearpower plant relay logic-processing cabinet testing method. By adopting the nuclear power plant relay logic-processing cabinet testing device and the method, long-time occupation of the working time of maintainers is avoided, the working amount of the maintainers is decreased, and introduction of human factor errors is avoided.

Description

technical field [0001] The invention relates to the field of nuclear power plant operation and management, in particular to a test device and method for a nuclear power plant relay logic processing cabinet. Background technique [0002] Due to the particularity of nuclear power for safety, the digital control system based on computer technology, communication technology and modern control theory was actually applied to nuclear power plants late, around the beginning of the 21st century, and it is usually considered that the full digital system is not completely trusted. In recent years, in order to prevent the common mode risk based on computer technology, the backup operation panel of the main control room based on the assembled instrument based on analog quantity technology and the relay logic cabinet based on relay logic, hereinafter referred to as ARC cabinet, are set up to jointly complete the countermeasures based on computer technology. The risk of common mode failure...
