Remote monitoring system of urban sewage treatment based on Internet

With the development of control network, Internet is used gradually in remote monitoring system. In order to develop the remote monitoring system of urban sewage treatment based on Internet, this paper takes CAN field bus as basal platform, combining CAN field bus with Internet technology. A new framework of remote monitoring system is introduced. The embedded system design of intelligent monitoring unit and motoring terminal, which are pivotal equipments in the monitoring system, is discussed in detail. Finally, the functions of remote monitoring system for urban sewage treatment based on Internet are described. The system is provided with not only excellent cost performance, but also running steadily and reliably.
