This system can realize water source detection, motor failure detection, processing and alarming. The independent detection circuit can realize the superelevation, the low warning water level can report to the police and superelevation warning water level process. On the principle of interface circuits, software design is the corresponding flow chart and the corresponding compilation of the main program, at the same time carries on the simulation with the proteus software. The result indicates that this system features good examination control function, the probability and extendibility.
