The Automatic Monitor And Forecast Of Flood Regimen System Based On GPRS

The automatic monitor and forecast of flood regimen system is the automatic system which adopt modem technique of real-time collection, transmission and analysis of hydrologic information, it integrate hydrologic information,telecommunication,computer and the freshly progeny of many other subject for resolving correlative problem about the monitor and forecast of flood regimen, its appearance changes the draggled state measuring the flood regimen data merely by manpower in the foretime, maximum improve the monitor and forecast speed, improve the forecast precision, and enlarge the forecasting area and content. dynamically real-time inspecting water level\flux and other flood regimen data is very important to flood prevention.The text particularly introduce the frndamental and implement method about the automatic monitor and forecast of flood regimen technique, mostly include the basic knowledge of the GPRS wireless communication technique and the main framework of flood regimen information collection system. On basis of absorbing and referring to the domestic and foreign advanced monitor and forecast of flood regimen technique, the hardware and software of the automatic monitor and forecast of flood regimen system which is based on GPRS wireless communication is designed.In the article, the specifications of this system are explained in detail, they are the most important of this part which are the system components of the flood regimen collection unit. the design of the system power, the realization of using the clock store chip and data store chip to store tiistorical flood regimen data, and the specific application of GPRS wireless communication for transmitting flood regimen data.Function, stability and reliability are final goals of the design of the instrument, on the premise of realizing the basic function, the instrument tries to optimize the design of hardware and software, comparing GPRS wireless communication with other communication modes, its huge advantages for the flood regimen information transmission are proposed specially.During the design of the instrument, the stability of the system is payed high attention to. the reset circuit is used in order that the instrument can work correctly, some corresponding measures are employed to avoid some disturbance in circuit. In the design of software, figure filtering is applied to improve the accuracy.
