Design And Realization Of Measuring Using Water Intelligent Supervision And Meterage System

Measuring using water intelligent supervision and meterage system completes real time supervision and meterage of irrigation area branch and trench passing water quantity, long-distance communications and synthesis information management by applying telemetering technique, computer technique, communications technique and so on, which provides efficient guarantee for irrigation works department measure and water resource attemperment management. The system is an important basic unit of water resource attemperment system, applies to each field of irrigation area, farmland irrigation works establishment measuring using water.The article tells of design and realization of PSTN intelligent supervision and meterage system emphatically and brings forward general design of PSTN intelligent supervision and meterage system in the first chapter including work principle of system, structure. Choosing type of flowmeter, RS-232, RS-485 transmission standard and I2C bus technique are introduced simply in the second and third chapter. The fourth chapter introduces data transmission in telephone network, puts important on ADSL, the fifth chapter discusses the PSTN material realization of system including choice of chip ,design of circuit principle chart and sofeware. In addition, the sixth chapter discusses simply two kinds of design projects of wireless intelligent supervision and meterage system.
