Design of Auto Dust Collection System in Different Regions of Blackboard

Abstract:

New blackboard dust collection system mainly be used for conventional teawching actions. It divided board into four different regions without changing basic structure, when people go into the view of sensor in the one of regions which will drive the quit fans to collect the dust produced during writing and clearing words on the board. The device includes two parts, mechanical structure and the region control system. For structure, be made up with up and down parts, the dusting devices and fans are chose by the stress analysis of the dust model, and then begin design work. For control system, using photo-electric switch to drive fans, and the angle of wind board is controlled by DC motor, and chip microcomputer STC89C52 is chose as the system core to achieve logical functions. The system can effectively reduce the harm from dust to the human and equipments during teaching. It has great characteristics including high efficiency and energy saving, low cost, simple structure, easy operation, high reliability and practicality.
