自来水感应开关控制器的设计与制作
[摘要]:我国是水资源短缺的国家,人均水资源量只有2200立方米,仅为世界平均水平的1/4。水的浪费既加剧了水资源短缺,也增加了污水排放量,加重了水体污染。
本课题以节约用水为目的,设计一个自动自来水开关控制电路。该电路能够在人们需要用水的时候,比如当手靠近自来水龙头时,通过感应装置,自动打开自来水开关,当手离开自来水龙头时,自动关断开关,起到既能避免交叉感染,卫生、环保,并且达到节约用水的目的,体现出现代生活的高质量。其中的原理可以推广到农业用水与工业用水,十分简便却起着很大的作用。

Design and manufacture of running water induction
 switch controller
 
 [abstract] : Our country is a country with shortage in water resources . The average water resource amount per person is only 2200 cubic meter, which is only 1/4 of the world average level. The wasting water behavior already intensified the shortage in water resources, while increased the sewage withdrawal, and aggravated the water pollution.
This topic therefore took saving water as a goal, and designed an automatic control circuit for running water switch. When people are in need of water, for instance, when the hand approaches the running water main item, through the induction installment, the circuit automatically turns on the running water switch. When the hand leaves the running water main item, the circuit automatic cuts out the switch. It already can avoid the overlapping infection, help the health, improve the environmental protection, and achieve the goal of saving water, while manifesting the modern life high grade. The principle may promote to the agricultural water use and the industrial water use, and it is extremely simple but playing a very major role.
