Embodiment 1
[0016] Use the call module of the Matlab test module to transfer a sub-function module of the protection logic into the execution module, and use the creation module of the Matlab test module to create a logic block with the same function as the transferred sub-function module according to the requirement specification, and Transfer the created logic block to the execution module, and use the input module to input and output the same dynamic input parameters to the sub-function module and the logic block, and then execute the two in the execution module to complete the automatic test. As a result, manually analyze and give the result of whether the sub-function modules under test meet the requirements. So far, the test of a sub-function module is completed. According to the above steps, each sub-function module of the protection logic is verified in turn, and all sub-function modules are completed. , and then test the entire protection logic according to the above steps, and ob...

The invention discloses a system for testing protection logic by utilizing Matlab and relates to the field of nuclear power control. The system comprises a computer and a protection logic module which is arranged in the computer, wherein the protection logic module is connected with a Matlab testing module which performs function test analysis. In the scheme, the whole protection logic program is divided into a plurality of sub-function modules according to composition and function, and the aim of completely verifying the protection logic is finally fulfilled by verifying performance of various sub-modules respectively. The scheme is simple in process and convenient to implement, saves a lot of labor and time, and solves the problem that a driving program and a stub program are needed to be programmed and hardware is depended in the prior art for testing the protection logic; moreover, the program operating in the scheme is the original program, the tested result is high in credibility, the influence brought by testing the program is not needed to be illustrated or considered, and the system provides a basis for safe operation of a digital instrument control system in a nuclear power station.
Description
technical field [0001] The invention relates to the field of nuclear power control, in particular to a system for testing protection logic in a nuclear power protection system. Background technique [0002] At present, the protection logic of the digital instrument and control system has the characteristics of configuration and configuration. The protection logic in each nuclear power plant protection system has the characteristics of complex relationships, numerous protection variables, huge program paths, and high reliability requirements. The work becomes extremely difficult and complicated, and usually depends on the hardware for the logic test in the main processor. During the test, it is necessary to write a driver and a stub program (auxiliary program) on the hardware for software testing, because the verified program is protection logic, so The requirements for the auxiliary program are very high, and its correctness, reliability and influence on the source program n...
