摘 要

随着社会经济的发展,人们的生活水平不断提高,相应着交叉感染的疾病也在不断地发生,以往人们洗完手进行干手都是利用毛巾擦干手上的水分,这样就造成了交叉感染的后果。这就引起了我们对人们日常生活中对洗完手,要进行干手的细节的关注。所以人们设计了干手器。本设计主要是采用了反射式红外传感器,利用了红外线实现对干手器开关的自动控制,红外线自动干手器的控制由红外发射(SE303)、红外接收(PH302)与电压放大(LM741)、音频译码(LM567)、延时电路(555单稳态电路)、驱动电路(继电器)几部分组成。本设计符合要求,能实现利用红外线来控制干手器进行工作。以至于满足人们日常生活中避免交叉感染的要求。

Abstract

Abstract

With the development of society and economy, people's living standard continues to improve, the corresponding cross infection diseases are constantly taking place, people used to wash your hands are dry hands are hand use towel dry water, thus causing cross infection of the consequences. This leads us to the daily life of the people of hand washing to dry hands, attention to detail. So people designed hand dryer. This design is mainly a reflection type infrared sensor, the infrared ray to realize the automatic control of hand switch, infrared automatic control device of hand by the infrared emission (SE303), infrared (PH302) and voltage amplification (LM741), audio decoding (LM567), time delay and driving circuit (relay) parts composition. The design meets the requirements, can realize the infrared control device for drying hands to work. That meet to avoid cross infection in the people daily life requirements.
