Problems solved by technology

According to the rules of the currently developed configuration software, the number of function blocks under a single logical configuration page must not exceed 128, and the entire logical configuration page is huge, so the comparison workload during the configuration debugging process is huge
[0003] The existing logic configuration page local comparison method, the configuration is completed, after saving, the configuration file is generated; the configuration file is saved in the local computer; the configuration file is used for logic configuration page comparison; the existing The logic configuration page comparison method is manual comparison, but manual viewing is used for comparison, which is easy to be overlooked, resulting in low debugging efficiency of configuration debugging, and hidden safety hazards in configuration debugging

Embodiment Construction

[0059] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0060] Such as figure 1 , the offline configuration comparison method of the distributed control system of the present invention, comprising:

[0061] Obtain two logical configuration pages that need to be compared, and obtain the reference configuration file and the configuration file to be compared;

[0062] Restoring the content of the benchmark configuration file as the program organization unit to obtain the benchmark program organization unit; restoring the content of the configuration file to be compared to the program organization unit to obtain the program organization unit to be compared;

[0063] According to the preset connection rules, connect the reference function block in the organization unit of the reference program with the reference connection line to obtain the first ref...

Abstract

The invention provides an off-line configuration comparison method and system for a decentralized control system. Starting from the most basic data storage structure of the logic configuration page, the logic configuration page can be compared efficiently by comparing the function blocks and connection lines in the logic configuration page Compared with the traditional manual comparison method, the comparison efficiency of the configuration page difference is higher. Avoid configuration inconsistencies caused by wrong configuration comparison results, and at the same time avoid configuration loopholes caused by configuration inconsistencies during the configuration process, improve configuration efficiency, ensure safe operation of the unit, and avoid potential engineering risks.

Description

technical field [0001] The invention relates to a distributed control system, in particular to a method and system for offline configuration comparison of a distributed control system. Background technique [0002] Distributed Control System (DCS) is the control core of a thermal power plant. In a large thermal power plant, a million-level thermal power unit has more than forty pairs of controllers, and a single controller can have up to 1,000 logical configuration pages. During the configuration and debugging process of thermal power plants, it is necessary to frequently compare tens of thousands of logical configuration pages. By comparing the results, the differences between the two logical configuration pages are shown. According to the rules of the currently developed configuration software, the number of function blocks under a single logical configuration page must not exceed 128, and the entire logical configuration page is huge, so the comparison workload in the co...
