GPRS通信在水文自动测报系统中的应用

Application of GPRS communication in automatic hydrologic data acquisition system

水情自动测报系统是20世纪80年代发展起来的,系统建设初期,通信大多以超短波为主,对测报系统而言,一般需建设一个或多个中继站来实现系统的通信,系统建设和运行维护费用较大。随着移动通信技术的快速发展,特别是GPRS通信的普及,使水情自动测报技术得到极大的提高。以辽宁省中小河流水文监测系统为例,介绍了水文自动测报系统的组成、通信方式、技术优势、主要功能等。实践证明,GPRS信道作为水情自动测报系统的通信媒介具有良好的发展前景。

The automatic hydrologic data acquisition system was developed in 1980＇s. In the initial construction period of the system, the major communication medium is ultrashort wave, for the data acquisition system, one or multiple relay stations needed to be constructed for communication, resulting in high operation and maintenance cost. Along with quick development of mobile communication technology and the popularization of GSM, especially GPRS communication, the technology of automatic hydrologic data acquisition system is improved greatly. Taking the automatic hydrologic data acquisition system for middle and small rivers in Liaoning Province as example, this paper introduces the composition, communication mode, technological advantages and main functions etc. of the system. The practice shows that utilizing GPRS as the communication medium of automatic hydrologic data acquisition system has good development prospects.
