摘　　要：首先介绍了可应用于核电站的中大型PLC控制系统,并提出PLC实时报警功能是控制系统的核心功能;其次进一步分析了控制系统产生报警的数据流、报警自动控制响应时间和报警数据实时显示响应时间;最后得出结论:中大型PLC控制系统对报警数据处理的实时性、高效性完全符合核电站数字化仪控系统需求。Firstly, this paper introduces middle-large size PLC control system based on the nuclear power stat ion, and states that real-time a -larm is the core function of PLC control system. Secondly, this paper makes furtlier analysis of data flow of generating alarm and the response time both in alarm automatic control and in real-time display of alarm data. Finally, this paper concludes that middle-large sisystem can fully meet the requirements of digital control system in nuclear power station for real-time and high-efficiency of alarm dataprocessing.
