基于红外感应原理的垃圾桶系统设计

Design of Garbage Can System Based on Infrared Induction

为了满足当前垃圾桶中具备安全实用方便、符合人机工程学等功能的需求,完成了一种能够感应人体活动并能自动开盖、闭盖、自动识别满箱等智能功能的垃圾桶设计,通过红外线传感器接收到由人体或者其他物体反射的红外线信号的变化,经过前置放大、比较以及延时等电路,从而实现了使垃圾桶根据人们使用要求进行自动开盖和关闭,同时在设计中添加了辅助红外线感应、满箱感应以及昼夜感应来完成各种智能功能,并且通过Multisim10.0对各种智能功能进行了仿真,实验结果表明,垃圾桶控制系统设计合理、可行。

In this paper, aiming at the requirement of convenient, practical and accord with ergo- nomics,a garbage can which incorporated cover automatic opening and locking, and detected the full of waste - bin was proposed. Through the infrared light intensity detector reflected by the human body or other objects, the signals after the process- of pre - amplifier, he comparator and the delay circuit could be used for automatic opening and locking of garbage can, at the same time, the system design had brought some intelligent functions, such as the aided infrared induction, identifying full of waste - bin, day and night induction,etc. And final- ly, some the simulation experiments were investi- gated through the software of Multisim 10. O, the experiment results indicated that the system exhibited the features of low - cost, and convenient to operation.
