谁能帮我把这段中文摘要翻译成英文的！！谢谢

The public toilet is modern society's one kind of infrastructure, it is the human culture evolution important product. Along with the population growth, the fresh water resource already lacked, if can the automatic control water washout, not only the people enter the restroom to be convenient, moreover to the economize on water is also not a small contribution! this topic designed two parts of electric circuits to realize the flushing water automatic control: The urinal flushing water automatic control system and washes the hands the pond flushing water automatic control system. Is mainly through the pyroelectric infrared sensor, the solid state relay, the solenoid valve as well as each control circuit's effective match realizes. After the pyroelectric infrared sensor catches the human body signal, passes through the amplifying circuit, the reshaping filter circuit, after timing circuit, the connection solid state relay, the solid state black-white control solenoid valve rea
