摘　　要：为了提高升旗控制的自动化水平,更加方便应用于各种体育赛事,基于西门子组态软件WinCC及S7-200 PLC,设计开发了自动升旗控制系统。控制系统通过采用PCAccess协议实现了上位机与控制器S7-200的双向通讯,采用USS通信协议实现了S7-200对变频器MM420的通信控制。在WinCC组态界面中,可以随意更新歌曲数据库,并对升旗实时监控。经过多次测试,升旗控制系统能够按照升旗歌曲的时间长度顺利完成升旗。说明,所设计的PLC自动升旗控制系统运行稳定可靠。In order to improve the level of automatic flag control system,and make it more convenient and flexible in various sporting events,the design of a monitoring system for automatic flag is presented by the Siemens configuration software WinCC and S7-200 PLC.The monitoring system＇s communication between computer and the S7-200 is completed through the PC Access protocol;between S7-200 and MM420 inverter communication is realized by USS communication protocol.In the WinCC configuration software,we can freely update the song database and real-time monitor the flag.Through several tests,the flag control system can successfully achieve according to the length of song.Note that the designed PLC control system can run stable and reliable.
