智能水位控制器的研究

The Research of Intellective Water-Level Controller

水资源紧缺已经引起全社会的关注。如何节约用水、有计划地用水已成为电子工作者设计供水系统时必须考虑的问题。自动化控制供水不失为一种行之有效的方法。该方法采用单片机来对传感器的信号进行处理,输出控制信号,配合外部硬件电路,用晶体管驱动直流继电器,再控制交流接触器来完成对水泵开启、关闭,设计可以根据缺水多少的不同情况智能化地启动不同数量的水泵,即缺水少时少量水泵工作,缺水多时多台水泵同时工作,及时补充水量。

The scarcity of water resources has attracted the attention of the entire society.The problem that how to save water has become the key point which should be thought twice by workers who design the electronic water supply system.Automated control of the water supply is a good method.This method is to use SCM to process the sensor signal,output the control signals,support with external hardware circuit,and use transistor to drive DC relays,then control the AC contactor for pumps to complete the opening and closing.It is designed to intelligently start different quantities of water pumps by different condition of water-lacking,It means a small amount of water pumps works when the lack of water is small.While the lack of water is large,many water pumps can work together and supply water in time.
