Abstract

The invention discloses a Loacl variable online monitoring method based on logical configuration generation. The method comprises the steps that first, a compiling mode of logical configuration software is utilized to generate a logical code; in the generated code, based on a security criterion carried in the logical configuration software, logic is switched into a unit independent in each step ofoperation; then, in a storage region of a lower computer, when a data storage region is allocated for input and output in each step, a backup region of the same size and type is allocated simultaneously; and next, a logic running result is monitored at each interface of the logic, and the logic is enforced at each input position. The method achieves the technical effect that a logical program generated by the logical configuration software is monitored and enforced.

Description

technical field [0001] The invention relates to the field of safety-level DCS of nuclear power plants, in particular to an online monitoring method for Loacl variables generated based on logic configuration. Background technique [0002] The logic configuration software used in nuclear power plants is a high-security software that provides developers with a complete model-based embedded development solution to reduce development costs, reduce development risks, and shorten verification time. [0003] In order to verify the correctness of the logic completed by the configuration software in a specific environment and to monitor and locate abnormal conditions that occur during operation, it is necessary to make every step of the logic execution visible, and only under the premise of visibility can the Analyze and process the running process. In order to make each step visible, it is necessary to monitor and force all variables generated by the logic, including external input,...
