摘　　要：使用三菱L02型PLC作为新污水处理控制系统的主站,并基于CC-Link通信协议扩展从站FX3U型PLC。罗茨风机、自吸泵、搅拌器和螺杆泵等使用变频器进行驱动,所有变频器由FX3U型PLC运用三菱通信协议控制。污水的MBR工艺和SBR工艺使用PLC流程控制,并采用触摸屏组态和办公室上位机组态画面同时操作,并行响应输出。远程监控模块连接触摸屏通信口获取污水状态数据,可发送远程报警短信并通过网页远程监控污水处理站。这种新的污水处理控制系统运用了4类通信技术,降低了布线成本且简化了污水处理系统调试过程,从而提高了污水处理系统的闭环控制和远程监控能力,显著提高了污水处理的运行稳定性。The Mitsubishi L02 PLC was used as the main station of the new sewage treatment system,and the station FX3U was extended based on the CC-Link communication protocol.The roots blower,self-sucking pump,agitator and screw pump were driven by frequency converter.All frequency converters were controlled by FX3U using Mitsubishi communications protocol.The MBR process and through the SBR process were controlled by the PLC process.The touch screen configuration and the office host computer configuration screen were operated simultaneously,and the output was parallel.The sewage status data were obtained by the remote monitoring module connecting the touch screen communication port,and the sewage treatment station could be monitored remotely by sending the remote alarm short message and the web page.By using the new sewage treatment control system based on four types of communication technology,the cost of wiring was reduced and the debugging process of the sewage treatment system was simplified.Furthermore,the closed-loop control and remote monitoring capability of the sewage treatment system were improved,and the operation stability of the sewage treatment system was significantly improved.
