自动化装置维护软件通信构件研制

Development on communication component of maintaining software for automatic devices

针对现场磁场对自动化装置间通信产生影响问题,提出了类套接字通信技术,介绍了自动化装置维护软件中的通信构件的开发方法。分析了软件的构件组成关系及通信构件在整个软件中所起的作用,论述了类套接字技术的串口通信基本原理。在此基础上,从链路层信息的发送、数据接收处理和通信报文校验3个方面,讨论了串口通信构件的具体开发方法。该软件已通过国家电力公司鉴定,并在自动化装置开发过程及众多的保护工程项目中得到应用,达到了设计要求,取得了明显的经济和社会效益。

Aiming at the problems of the electromagnetic interference in automatic device communication, the similar socket technology is presented and the development method about communication component of maintaining software for automatic devices is introduced. Firstly, the software composition relation and the communication component role are studied. The basic principle of serial port com- munication using similar socket technology is discussed furtherly. On this basis, the concrete method of developing serial port communication component is discussed from link layer information sending, data receiving, handling and checkout. The software is finished, identified by state power corporation and used in the development of every protection automatic device and a lot of project successfully. It meets the design requirements and achieve obvious social benefit and economic benefit.
