Research On Intelligent Constant Pressure Water Supply System Based On Network Technology

Urban water supply system is a large project, Involving electrical control, information exchange, network, communication and network, buildings, etc, This paper studies the constant pressure water supply system of intelligent network communication and the main water pumping station or secondary compression field control site.Papers on the constant pressure water supply system is studied, and probes into the water pressure constant pumping out of control and pump outlet pipe pressure control scheme for the remote real-time, so as to ensure a few kilometres away several kilometers from the district or water pressure constant or unit.In the constant pressure water supply system in the conventional PID plus feedforward control scheme for water supply system, improve water quality, safety and studied. To make electricity generator in process of pressure changes as small, "phase synchronization of automatic control" and "hot" strategy for frequency are discussed.Discusses the characteristics of urban water supply pipe, water pipe network monitor realization, puts forward the "network control layer, site monitoring and controlling the layer" three-layered structure. Macro, if we put water supply pump or nodes as several subsystems, and they constitute the urban water supply control station supervisory control structure. In common scene network topology structure, we choose the bus structure as water supply system of communication structure and fieldbus technology of industrial Ethernet, that has become the mainstream fieldbus technology, and probes into the remote monitoring system based on Web structure, and utilities Internet network can realize constant pressure water supply system of remote monitoring and warning and maintenance, etc.The paper is based on the network constant pressure water supply system for the development and design, according to the requirements for the communication system network topology structure design, urban water supply network structure and supply subsystem structure and GPRS communication series topology. Thus, we can be on the system network hardware and site selection and utilization control equipment industrial Ethernet realize remote monitoring. At the same time, discusses the control scheme, we choose, urban water supply network structure of typical subsystem, for example to on-site control scheme of system design, the design of information security.Based on the working process of the working process (guide) for vocational education teaching ideas, the training object, teaching ideas, vocational education by "working process oriented teaching design thought of the understanding and the working process was put forward based on the teaching practice, based on the working process of the thesis portions of the core ideas will realize technology in teaching.
