大型城市污水输送SCADA系统通信网络设计与实现

摘要

Through analysis of the several communication technology,according to SCADA system in the metropolitan sewage transportion,completely unattended operation in the sewage pumping station.Used MPLS-VPN technology to upgrade the communication network of the central monitoring system of the first stage of the Shanghai sewerage project that had run for 24 years.We complete integration stable transmission SCADA system in the metropolitan sewage transportion pumping station data and video image of the equipment running,Security precaution information according to the high reliability,high safety,scalability and good economical efficiency over the MPLS-VPN technology.It injection new vitality for the tradition of SCADA system in the metropolitan sewage transportion that had stable run for 20 years.%通过对数个通信技术的分析,依照城市污水输送SCADA系统完善污水泵站无人值守运行要求,应用MPLS-VPN技术对运行24年的上海合流污水治理(一期)工程中央监控系统的通信网络实施升级改造.以MPLS-VPN技术所提供的高可靠性、高安全性、易扩展性及良好的经济性,完成整合泵站设备运行数据、泵站安防信息数据,以及泵站设备运行及泵站安防视频图像的城市污水输送SCADA系统数据的稳定传输,给稳定运行二十多年的大型城市排水传统SCADA系统注入了新的活力.
