Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 2 Shown is a nuclear power plant backup panel control equipment test system, including:

[0044] Status feedback light 5, used to indicate the start or stop status of the backup disk control device;

[0045]The signal processing unit 4 is used to process the start command or stop command issued by the backup disk control device under the backup disk 1 in the backup disk test mode, so as to generate a status indication signal and send it to the status feedback lamp 5 . The signal processing unit 4 is arranged in the backup disk control logic cabinet 2, and the start command ...

Abstract

The invention discloses a nuclear power station backup disk control device test system comprising a state feedback lamp which is used for indicating the start or stop state of a backup disk control device; and a signal processing unit which is used for controlling the working state of the state feedback lamp according to a start command or a stop command sent by a backup disk in a backup disk test mode, and the signal processing unit is arranged in a control logic machine cabinet of the backup disk. The invention also provides a nuclear power station backup disk control device test method. Normal operation of a nuclear power station is not influenced by the nuclear power station backup disk control device test system and method.

Description

technical field [0001] The invention relates to the field of nuclear power, and more specifically relates to a test system and method for backup disk control equipment of a nuclear power plant. Background technique [0002] Before the introduction of DCS instrumentation and control technology, nuclear power plants used conventional hardware boards to realize the operation and control of the power station. Tests are carried out at planned intervals to detect potential failures and check the operability of control equipment to ensure the reliability and availability of control equipment. However, the existing technical solutions mainly verify whether the control equipment is available by sending a real control signal from the control equipment and driving the action of the on-site actuator. [0003] Such as figure 1 Shown, its test method and steps of the technical scheme of the prior art are described in detail as follows: [0004] The operator in the main control room exe...
