為了實現(xiàn)水文測報系統(tǒng)的高可靠性、低功耗性和較好的實時性，詳細介紹了水文測報技術(shù)的基本原理和實現(xiàn)方法，主要包括GPRS無線通信技術(shù)的基本知識和水文信息采集系統(tǒng)的整體構(gòu)成。在借鑒和分析了國內(nèi)外水文測報技術(shù)的基礎之上，設計出了基于GPRS的水文測報系統(tǒng)的軟硬件系統(tǒng)，并利用組態(tài)王開發(fā)了水文測報系統(tǒng)的實時監(jiān)控系統(tǒng)。整個系統(tǒng)以實用、穩(wěn)定、可靠為目標，在保證實現(xiàn)基本功能的基礎上，優(yōu)化了硬件和軟件設計。實驗結(jié)果證明，該系統(tǒng)采集數(shù)據(jù)正常、工作穩(wěn)定、通信良好，實時性強。

　　Abstract:

　　In order to realize the hydrologic data acquisition system in high reliability， low power dissipation sex and better realtime，the text particularly introduced the basic principle and implement method about the hydrologic data acquisition technique，mostly include the basic knowledge of the GPRS wireless communication technique and the main framework of flood regimen information collection system. On the basis of absorbing and referring to the domestic and foreign advanced hydrologic data acquisition technique，the hardware of the hydrologic data acquisition system which is based on GPRS wireless communication is designed，and using the Kingview developed the monitoring system of hydrologic data acquisition system. Function，stability and reliability is a final goals of the design of the instrument.The instrument tries to optimize the design of hardware and software on the premise of realizing the basic function. Experimental result shows it is stable and reliable.
