摘要
利用反射式红外传感器和少量的电子器件(单稳态触发器),研制了智能型节水控制系统。该系统能够识别是否有人入厕,酌情产生冲洗信号,躯动进水电磁阀开启,向浮球式水箱内注水,待注满足以冲刷干净所需的两水箱水后,便自动地切断电磁阀中电源,达到了既卫生又节约的目的。在某一教学楼应用该系统一年多来,与无使用此系统的同规模另一教学楼相比,节水约70%。该系统元件少、成本低、结构合理、工作可靠、安装容易、维修方便,有广阔的应用前景。
Utilizing reflection type infrared sensor and small electronic devices（monostable multivibrator）, the authors have developed the intelligent water-saving control system. This system can discern whether someone enters the lavatory, produce the signal of washing according to the cirumstances, drives the electromagnetic valve to open, and pour water into the floater type cistern. After filling two cisterns of water enough for cleaning, it＇ll cut off the power in the electromagnetic valve automatically, This system has achieved the sanitary and economical purpose, using this system can economize water by about 70%. This system features few components, low costs, rational structure, reliable work, easy installation, and convenient maintenance, has a wide application prospect.
