基于嵌入式GSM模块的水文监测系统的设计

摘要

依托完善的移动通信网络,采用西门子公司的嵌入式GSM模块MC35,辅以计算机、单片机、双音多频信号发生器UM91210和解码器MT8870、水位传感器等构成江河水位监测系统,由监测中心和多个监测点的监测子机组成,监测子机的监测数据通过MC35以短信方式上传给主机,上传的时间间隔可自动调整,也可由主机发送指令设定,还可通过移动通信的话音通道用双音多频信号传送.%Depending on the perfect mobile communication net, the water leveling monitoring system is mainly composed of the embedded GSM Module MC35 which is produced by Siemens Corp, as well as computer, SCM, dual tone multiple frequency (DTMF) signal generator UM91210, decoder MT8870 and water leveling sensor. The system includes a host-machine in the monitoring center and monitoring submachines at many monitering points. The monitoring data acquired by the subma-chines is delivered to the host-machine by MC35 via SMS. The transferring interval time of the data can be automatically adjusted, or appointed by the host-machine, or transferred by DTMF .signal of the tone channels.
