摘　　要：为了实现对水库的环境参数有效稳定地进行远程监测,对过去的水文遥测系统进行了研究和需求分析,并设计了一种基于ARM平台的无线通信水文遥测站。为改善以往系统基于单通信方式上,存在信道故障会造成通信不顺畅的问题,构建了一种基于双信道的通信网络系统方案。在传输信道的使用上优先利用GPRS网络传输数据,并将北斗卫星网络作为系统的第二信道加以组网,当传输失败时,则利用卫星设备进行传输。通过实际的工程项目应用测试,结果表明双信道的畅通率明显优于单种通信方式,实现了水文遥测系统的实时监测,稳定的数据传输,有效降低了丢包率。In order to achieve effectively and stably parameters of reservoir environment remote monitoring, the paper design a hydrological telemetry station of wireless communication based on ARM platform after studying the past hydrological telemetry system and analyzing the requirements. To improve the previous system based on single communication mode, channel fault will not smooth the communication problems. This paper constructed a communication network system scheme based on double channel. On trans—mission channel system priority to transmit data using GPRS network, in addition to network the plough satellite as the alternative transmission channel, when the transmission failed, the system transmit through satellite termination. Through the actual project application testing,results show that the flow rate of the double channel was better than single communication mode, to realize the real- time monitoring of hydrological telemetry system, the stability of data transmission,effectively reduce the packet loss rate.
