Abstract

The invention relates to a test method and system for verifying a logical operation function of a DCS simulator, and belongs to the field of nuclear power system testing. The method comprises the following steps of: presetting an input setting and an expected result according to the logic required to be verified, forcibly inputting a DCS simulator to perform a logical operation simulation according to the input setting; comparing an output operation result of the DCS simulator according to the logical operation simulation with the expected result to generate a test result judgment table; and obtaining a test result of the logical operation function of the DCS simulator according to the test result judgment table. The method overcomes the problem that existing test methods are low in verification efficiency and easy to introduce human errors, thereby effectively improving the test efficiency and accuracy.

Description

technical field [0001] The invention relates to the field of nuclear power system testing, in particular to a testing method and system for verifying the logic operation function of a DCS simulator. Background technique [0002] The nuclear safety level DCS simulator system is mainly used for the training and examination of nuclear power plant safety level DCS operators to assess the ability of the operators to actually operate the nuclear power plant control system or guide others to operate in accordance with the relevant regulations of the nuclear power plant. The nuclear safety level DCS simulator is a simulation system based on the nuclear safety level DCS. Its characteristic is that when the input is the same, the output of the DCS simulator system is consistent with the output of the actual DCS system. The main functions of the DCS simulator are divided into teaching function and DCS simulation function, and the DCS simulation function is composed of the following par...
