Yuanmou County Domain Automatic Hydrological Forecast Site Selection And Analysis Of The Wireless Relay Station For Communications Systems

The automatic system of hydrological data telemetering and forecasting with applications of the technology of telecommunication, telemetering and computer, is one kind of advanced water information real-time collection processing systems, a modernized method for flood-control. It collects, transmits and forecasts dates of rainfall,water level, water flow of streams, reservoir and rivers in real time.This thesis makes a test and analysis of the radio communications system of the automatic system of hydrological data telemetering and forecasting of Yuanmou. Based upon the dates obtained from the test and position date of communication repeaters chosen carefully by the author, the evaluation of the system is also made in this thesis which provides a scientific basis for the foundation of the system for water conservation department.The first chapter introduces the main work of this paper and the statues of the automatic system of hydrological data telemetering and forecasting. The second chapter displays the national standards of the system and the index of the equipments used in this paper. The third chapter presents a model of the related radio communication system; The fourth chapter shows the procedures of the test with its results analyzed by the author in chapter five; Finality, summaries and suggestions are made in chapter six.
