Description

technical field [0001] The technology belongs to the field of automatic control and automatic test, and specifically relates to a test device and method for an automatic system of a control system of a nuclear power plant. Background technique [0002] The digital instrument and control system of nuclear power plants is the "nerve center" of nuclear power plants, controlling the safe and efficient operation of the entire nuclear power plant. The nuclear power plant control system is an important part of the safe and efficient operation of the nuclear power plant. Its main function is to control the process system of the nuclear power plant, protect the safe operation of the nuclear reactor, prevent the leakage of radioactive substances into the natural environment, and ensure the safe operation of the nuclear power plant. [0003] Relevant laws, regulations and standards put forward strict requirements on the design and implementation process of nuclear power control system,...

AI Technical Summary

Problems solved by technology

[0004] Traditional test methods usually use manual input of test signals, observe or record the corresponding output signals, and perform manual confirmation by comparing with expected values. The test efficiency is low and the cycle is long. Often creates duplication of work, leading to increased project labor costs

[0005] At present, there are some test methods for the control cabinet of nuclear power reactor protection system, through industrial computer, field acquisition card, signal processing distribution board, conditioning board, etc., to achieve a single control cabinet or a special test tool developed for a specific platform , can only be tested for specific preset functions

[0006] In addition, when the scale or semaphore of the system under test increases or decreases, basic configurations such as hardware and software need to be modified according to the needs of the system under test. The system has poor scalability and low reusability.
