热释红外与声光组合控制喷水系统电路设计

Circuit Design for Sprinkler Controlled by Pyroelectric Infrared and Acousto-optic Aggregate

热释红外与声光控制组合喷水系统主要用于水景喷泉方面。该设计主要由热释红外控制电路,声光控制电路,三相交流控制电路,水泵和彩灯组成,实现了不论白天或夜间只要有人在喷泉周围活动时驱动水泵喷水,人离开便停止的功能。在夜间其周围有声音信号时,声光控制电路自动开启,使水下彩灯发光并与热释红外控制电路并行驱动水泵喷水。持续一段后系统将自动关闭并等待下一个红外和声音控制信号的出现。通过重复该过程,实现了全天侯自动化喷水,夜间发光和节能降耗的要求。

A water- spraying system controlled by pyroelectric infrared and acousto- optic aggregate is mainly for waterscape fountain. We can realize all - day water - spray automatically with the system. This system is mainly composed of pyroelectric infrared control circuit, the acousto - optic control circuit, three - phase AC control circuit and the power source etc. At any time, when people move around the fountain, the pyroelectric infrared control circuit will drive the water pump and spray water, and when people leave, the water pump will stop spraying. At night, when there are some sound signals around the fountain, the acousto - optic control circuit will be turned on automatically and make the under - water color lanterns illuminate, at the same time, the acousto - optic control circuit will drive the water pump and spray water with the help of pyroelectric infrared control circuit. The fountain will spray for some time, then the system will be turned off automatically and wait next appearance of infrared signal and sound signal, the process which has been described will be repeated.
