Automatic controlling system of flushing is composed of Chinese 100 RAM PLC with single chip microcontroller STC89C52RC as its controlling core, proximity sensor and magnetic valve as the output- terminal executing device. The hardware and controlling program are designed in this paper. The practical application more than one year demonstrates that the system is of high sensitivity and high stability. Meanwhile, the circuit of hardware is so simple that it is easy to maintain. In the aspect of software,the ladder program will be applied in different places once modified a little, and therefore the system is of good universality and low cost. In total, the system saves water and there will be good prospect.
