Research And Construction Of DCS Logic Automatic Configuration Web Platform

DCS control system is widely used and is the core intelligent system of industrial production.Configuration is an important part of DCS project implementation,including the process of measuring point list,equipment list,function manual,logic diagram drawing and other processes.At present,the stage from the test point list to the equipment list occupies most of the engineering staffs time,but the real logical configuration work is far less time consuming than this part.If the configuration can be completed in an automated way,it can greatly reduce labor and operating costs,and achieve the purpose of improving quality and efficiency.Carrying out research and design work around the DCS logic automatic configuration WEB platform has great engineering application value.This paper uses front-end and back-end technology to design and build a DCS logic automatic configuration WEB platform.First,research,analyze,and imitate the information extraction process from the test point list to the equipment list for engineers,build a mechanism to extract device information based on verb lexicons and verb matching rules,and design a test point-device generator.Then,a new concept of "device behavior matrix" was proposed to describe the logical relationship of a device’s behavior status,behavior selection,operation type,allowable conditions,chain conditions,and protection conditions.Logical data was stored in the form of JSON strings.Designed the equipment configuration function module.Then,based on the experience and process of engineers writing project engineering specifications,the engineering specification generator was designed to realize the functions of extracting logical storage data,analyzing words,and automatically generating engineering specifications according to templates and exporting them with one click.Finally,the DCS configuration WEB platform interface is designed and built by using front-end technologies such as html,css,and js.Taking the engineering projects of the two power plants as the test cases of the DCS logic automatic configuration WEB platform,the equipment list is generated from the test point list,and the engineering specification is automatically generated from the device logic configuration.The platform has achieved the expected design functions and aims.The test results show that the DCS logic automatic configuration WEB platform not only reduces labor costs,improves production efficiency,but also improves accuracy.
