Design of surface water monitoring based on AVR microcontroller and LabVIEW

Two key problems must be solved in the surface water monitoring,one is long-distance data transmission problems,the other is the power to the monitor.In order to solve these two problems effectively,the design used Siemens TC35i module and clock timing chips to control the working hours of low-power AVR microcontroller and phone modules.The PC-monitor-interface used LabVIEW software was also simple and clear,it can display real-time data;analyzes the trend of the data-curve;warns much earlier;LabVIEW uses LabSQL connected to the database,completes network share of data,makes the monitoring system easily becoming a network node.The practical of result shows that the design is simple,good controllability,high reliability.
