摘要
介绍了基于工业以太网混合模型的污水处理监控系统的硬件配置及其功能的软件实现。现场级采用西门子S7-300系列PLC做主站,分布式I/OET200做从站,构成PROFIBUS-DP总线控制系统。上位机选用工控机,利用WinCC组态软件开发工艺流程、参数设定、实时曲线等监控画面,采用基于TCP/IP协议的工业以太网与PLC通讯并与大厦BA相连,实现了管控一体化。运行结果表明,该系统保证了污水处理过程的工艺质量,运行稳定可靠,提高了管理水平。
This paper introduces the hardware configuration and the software achievement of monitoring and control system based on mixed model of industrial Ethernet for sewage disposal. SIEMENS S7-300 PLC is used as master station and ET200 distributed I/O device as slave station to compose PROFIBUS-DP control system. Industrial personal computer is chose as the upper computer and WinCC is used to develop monitoring and control picture such as technologic flow, parameter setting, real-time curving. PLC and IPC is communicated via industrial Ethernet based on TCP/IP to form a hybrid control system, which realize the integrating management and control by linking the BA together. The results of operation prove that this system ensures the technical quality of the sewage disposal and works steadily as well as improves the management level.
