摘　　要：针对目前市场上的干手器分立元件较多、电磁滋干扰强、成本高、速度慢、干手效果不明显等问题,设计了一款基于单片机的智能干手器。该系统采用51单片机节制电路和红外感应电路,克服了以上缺点,能够快速、自动感应人手的伸进和离开,通过软件智能加减工作时间,还能自动调节或手动改变出风口温度,分别满足不同人、不同条件的需求。该系统实现了智能干手功能,操作简单、运行可靠、系统稳定,能达到设计要求和精度指标。At present, there are many problems in the hand dryers, such as more discrete components, strong electromagnetic interference, high cost, slow speed, unobvious effect of dry hands, and so on. In order to solve these problems, this paper designs an intelligent hand dryer based on MCU. The system adopts 51 MCU control circuit and infrared induction circuit to overcome the above shortcomings. It can quickly and automatically sense the entering and leaving of human hands. It can also intelligently add or subtract drying time by software, and intelligently adjust outlet temperature according to ambient temperature and humidity. This can meet the needs of different people and different conditions. The system realizes the function of intelligent dry hand, and is simple to operate, reliable to operate and stable, and it can meet the design requirements and precision targets.
