摘　　要：介绍基于研华工控机与S7-200 PLC的厌氧消化过程数据采集系统的实现。PLC对厌氧过程进行实时数据采集,并通过RS-485总线传输数据到上位机。上位机人机界面采用VB6.0结合NI Measure Studio编程实现,应用PComm串口通讯开发工具实现后台通讯。可以实时采集厌氧消化过程的各项关键现场参数,监视PLC的工作状态并可进行数据保存、查看、打印与分析等操作。运行结果表明:该系统易于用户操作,运行可靠,提供了一种高效的厌氧消化过程实时数据采集的实现方法。Implement of the data acquisition system for anaerobic digestion process based on PLC and Visual Basic6.0 programming on host computer was introduced.Advantech industrial computer acted as a host and the PLC acted as a remote unit.A human-machine interface on host was implemented which provided user a friendly operation interface.The host can acquire data real-timely from remote unit and refresh the human-machine interface correspondingly with intercommunion.The running result shows that the system is easy to use and has reliable performance.
