The sub-master stations and monitoring stations, through the master control station's keyboard can be achieved on the water level monitoring stations of the upper and lower limits of the control and display. Master station and the monitoring and control stations of the wireless real-time data transmission solutions are widely used in munications SMD technology. Come from the monitoring station to send the data through user-friendly man-machine interface for LED display devices to exchange data in real-time data display. The system, through the microcontroller serial port munication puter functions and use of the can be achieved on the remote reservoir water measurement and automatic control, this real-time monitoring of river water level is very useful. System uses a powerful C language development, and separately in the software and hardware design using Protel 99se, keilC51 development platform. The results show that the system has a cost-effective, easy to operate, visualize and so on.
