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.
