There are two key issues in the surface water monitoring, one is long-distance data transmission; second is the power to the monitor. The design uses Siemens TC35i module to transmit data, uses clock timing chips to control the working hours of low-power AVR microcontroller and phone modules. So the two problems are solved effectively. The PC-monitor-interface used LabVIEW software is also simple and clear, it can display real-time data; analyzes the trend of the data-curve; warn much earlier. The practical of result shows that the design is simple, good controllability, high reliability.
