【摘要】 为了满足电厂综合自动化的发展要求 ,特别是适应设备状态检修 (优化检修 )的需要 ,机组监录系统对数据远传提出了更高的要求。利用NT环境下多线程技术 ,依据电力系统基本远动配套标准IEC 6 0 870 5 10 1规约 ,实现机组监录系统的数据远传。通过在主线程中建立数据接收子线程和数据处理子线程 ,将数据接收和处理从主线程中分离出来 ,从而大大提高了数据传输的实时性和可靠性。着重阐述了采用VC + +的MFC实现多线程编程的软件设计思想 ,以及IEC 6 0 870 5 10 1规约的应用更多还原

【Abstract】 In order to meet the demand of power plant automation development,especially the demand of condition based maintenance,the remote data transmission function of the state detection and record system for generator transformer unit has to be enhanced.According to the companion standard for basic tele control tasks of electric power system,IEC 60870?5?101 protocol, the multithreading technique under NT environment is adopted to realize the remote data transmission of the G?T state detection and record system.By separating the data acquisition sub thread and the data processing sub thread from the main thread,the real time performance and reliability of the remote data transmission can be greatly improved.The SW design concept of using VC++’s MFC in multithreading programming and the application of IEC 60870?5?101 protocol are emphasized.更多还原
