Research For Water Source Well And Water Supply Pipe Network Remote Monitoring System

With the development of science and technology and progress, wireless remote monitoring system (SCADA, Supervisory Control and Data Acquisition) is widely used in people’s daily life and industrial production. The water sector to install water wells and pipe network of wireless remote monitoring system can real-time monitor every water supply link, enabling the operator to dispatch management convenient and timely, effectively protect the user demand, to ensure the normal operation of industrial production. At present, most of the city and area have installed the monitoring system of water supply, many enterprises are also installed the monitoring system of water supply, to achieve a reasonable scheduling of water demand. But the monitoring system of water supply and water supply departments of many old, data sharing ability is poor, the low degree of automation, low system reliability, the low level of information technology, the water source well and the water supply pipe network independent management, the existing technical problems need to be resolved. The design of the digital radio remote wireless communication technology, Web network technology, PC configuration technology as the foundation, build water wells and water supply network wireless remote monitoring system, combined with regional characteristics, water demand in water supply area water supply department, has realized the data acquisition, real time monitoring, wireless remote data transmission, short message alarm, database memory calls, Web publishing, dynamic visualization interface display function.First introduces the basic objective and significance of the research on wireless remote monitoring system, the domestic and foreign research, pointed out the problems of water supply monitoring system. The future direction of research and development of monitoring system of water supply, detailed description of the wireless remote monitoring system based on technology, the function demand for the water supply system is analyzed, the characteristics of water supply of a water supply sector as the basis, through the theoretical research and the design of hardware, the system network architecture, the system is divided into hardware, software, communication and other parts, the water source well and pipe network of wireless remote monitor technology improvement.Data communication method adopts the master-slave mode, data monitoring point data acquisition based on RS-485bus transfers to sub station, the wireless data transceiver sends the data to the master, master the data stored in the database, and then the analysis and processing of these data, dynamic display in the upper unit configuration screen. Using the GSM SMS module that operators can whenever and wherever possible to monitor the running state of the system through mobile phone text messages; technology can realize the query data released by the Internet application of Web network; the use of database technology, to achieve a good data analysis, processing, call the function.The design of the hardware part of the analog acquisition module, PLC, digital radio, Ethernet module, the hardware implementation of coordination, accurate data acquisition, improves data transmission speed.Field application shows that the system is accurate, data transmission, the transmission of low bit error rate, strong anti-interference ability and high reliability, effectively solves the problems existing in the traditional water supply monitor system.
