摘 要: 为实现河流水位信息的实时远程监控,提出基于GPRS和Internet的河流水情实时远程监测系统解决方案。以STC12C5A60S2单片机作为系统控制中心,控制水位传感器进行河流水位信息的采集和处理,并控制GPRS通信模块进行数据传输。选用LC?SW1型水位传感器测量水位,使用SIM900A无线通信模块作为GPRS通信模块。监控通信网络通过具有公网IP的服务器建立,网络连接方式为TCP,将远程监测端的数据和监控端连接。该系统具有成本低和监控范围广的优点,能够满足应用的要求。关键词: 水情监控; GPRS网络; 网络通信; SIM900A中图分类号: TN967?34; TP277 文献标识码: A 文章编号: 1004?373X(2016)06?0132?04Research on river water regimen real?time remote monitoring system based on GPRS and InternetJIA Jianke(School of Physics and Telecommunication Engineering, Shaanxi University of Technology, Hanzhong 723003, China)Abstract: To realize the real?time remote monitoring of river water?level information, a solution of river water regimen real?time remote monitoring system based on GPRS and Internet is proposed. The microcontroller STC12C5A60S2 is taken as the system control center to control the water?level sensor for rivers water?level information acquisition and processing, and control the GPRS transmission module for data transmission. The LC?SW1 water?level sensor is selected to measure the water?level, and SIM900A wireless communication module as GPRS communication module. The monitoring communication network is established with the server owning public network IP, and its connection mode is TCP to connect the data from remote monitoring side to the monitoring side. This system has the advantages of low cost and wide monitoring range, and can satisfy the application requirements.Keywords: water regimen monitoring; GPRS network; network communication; SIM900A

我国河流多,河流水位变化大,尤其在汛期,河流水位在暴雨和山洪的影响下迅速上涨,给人民的生产生活带来不可估量的损失。目前国内许多河流水情的监测主要依靠水文站观测人员进行观察、逐级汇报的方式,该方式不仅需要大量的人力,而且很难做到及时、准确地了解河流水情状态。特别是在遇到暴雨或特大暴雨时,观测人员很难进入观测地点,各种数据的采集与传递都无从谈起,势必引发灾难性的后果。因此,加强对河流水情的实时远程监测就显得极其重要。虽然现阶段国内一些公司企业设计了水情监测系统,但购买成本高,运行费用也高。GPRS(通用分组无线业务)无线通信网络已经遍布世界各地,覆盖范围及其广泛,可靠性高,且收费相对低廉,数据传输速率最大可达到171.2 Kb/s,同时GPRS网络能接入Internet网络,实现数据的大范围远程实时监控[1?2]。……
