摘　　要：气体变送器实时测控系统是工业控制计算机,现场测量转换设备气体变送器,通信设备和网络,系统测控软件以及其他一些外围功能设备模块的有机结合。本文主要介绍了测控系统软件的设计。该软件通过对多串口的循环采集获得实时数据,并定时记录到数据库中。友好的人机界面提供实时信息的显示和查询,允许操作人员进行仪器参数的设置,并能访问数据库获得历史曲线,同时兼有报警输出和断电恢复功能,保障了安全顺利的工业生产。Gas device collect and control system is an organic combination of computer,collect devices,communication devices and network,control software and other function modules.This paper discusses the design of the software. The system collects real-time data from devices by several Corns in turn and puts the data into the database every 30 minutes.Friendly interface between computer and user supplies show and inquiry of the real-time data,allows users to set parameters of the devices and can show history trend. Meanwhile,it can give a warning signals output and recover from power failure which ensures the safety of product process.
