Abstract: Wireless hydrological automatic measurement system(WHAMS) based on GPRS is provided. In WHAMS, data collected by hydrological data collection instruments is transmitted to data processing and monitoring center through GPRS wireless communication network of mobile. The system collects, transmits and processes hydrological data automatically and has advantages of real time, high efficiency, high accuracy, low investment, low running cost, etc. It solves many serious problems such as human labor is needed to take care of the manual measurement instruments and to keep an eye on it all the time, data collecting, processing and handing in involves human labor, data measurement, recording and transmission is not real time resulting in water allocation and in-time flood prevention can’t reach first hand data in time. The system has nontrivially social and economical benefits.

摘要： 提出了一种基于GPRS的无线水文自动测报方案，水文数据采集设备将采集到的水文信息利用移动网的GPRS无线网络可以及时发送到数据处理和监控中心。该系统实现了水文信息采集、传输和处理的自动化，具有及时、高效、准确、基建投资少、运行成本低等特点，解决了人工观测记录设备需要有专人管理、值守、记录、整理和上报，无法实现实时对水文信息测量、记录和传输，无法为水资源调度和防汛实时提供数据等重要问题，具有显著的社会效益和较大的经济效益。
