基于MCGS的污水处理集散控制系统的设计

针对日益突出的污水问题，设计了将上位机组态软件MCGS同下位机S7 200的PLC控制系统组合在一起的污水处理集散监控系统。首先介绍了控制系统的硬件结构、工作原理，然后对PLC的软件程序进行设计并通过工控组态软件MCGS能够实现对污水处理系统运行全程的实时自动监控。最后利用计算机模拟技术实现了对PLC控制系统的整体模拟和调试。实验证明：该系统运行顺畅，性能可靠，人机交互界面友好，自动化水平有效提高，具有良好的市场前景及应用价值。

Design of automatic door monitoring system based on the MCGS

In view of the increasing prominent sewage problem, the sewage treatment distributed control system was designed combining the host computer configuration software MCGS with the lower computer of S7 200 PLC controlling system. First the hardware structure and the working principle of the control system were introduced. Next the PLC software program was designed and the whole operation real time automatic monitoring of the sewage treatment system through the MCGS configuration software could be realized. Finally, the overall simulation and debugging of PLC control system using computer simulation technology was achieved. Experiments prove that the system runs smoothly and has reliable performance, friendly man machine interface, high level of automation, and the good market prospect and application value.
