摘  要
 随着社会的进步和发展，人们的学习、工作越来越繁忙，于是怎样更大程度地将人们从烦琐的日常事物中解脱出来，就成了新一代家电所追求的目标，而自动化正是这一目标的集中体现。
 本文介绍的全自动吸尘器初步实现了无人情况下的自主工作方式。它自带电源，利用了超声波测距的原理，通过向前进方向发射超声波脉冲，并接收相应的返回声波脉冲，对墙壁等进行判断；通过以单片机为核心的控制器实现对超声发射和接收的选通控制，并在处理返回脉冲信号的基础上加以判断，选定相应的控制策略；通过驱动器驱动两步进电机，带动驱动轮，从而实现行走转向等功能；通过红外线热释电传感器对人的活动进行检测，减少人对吸尘器行走的影响。在吸尘器行走的同时，由其自身携带的小型吸尘部件，对经过的地面进行必要的吸尘清扫。

Abstract
Along with development and the progress of society, work and the study of people are more and more busy, so how larger degree land frees people from overelaborate daily thing, have become the goal that new generation home appliance pursues , and automation is just the concentration of this goal to embody.
The full automatic dust catcher of the introduction of this paper has realized the autonomous working way under unmanned condition preliminarily. It has used the principle of supersonic range finding from electrified source , judges through entering direction projection supersonic pulse forward, taking over the corresponding return pulse of sound wave and waiting for wall to go on; Through with sheet Pian machine for core controler realization for ultrasound projection with take over choose know control, and in handling return pulse signal on foundation judgement, choose corresponding control strategy; Through actuator drive, two steps drives drive wheel into generator, so realize to walk change direction etc. function; Pass through the heat of infrared ray Shi the campaign of faxing sense ware for person carries out detection, reduce person for dust catcher walk influence. When dust catcher walks at the same time, the aspiration that carries out necessity for the ground of process by the small-sized aspiration parts that self carries settles to sweep.
