Abstract
|
Carpets can provide a comfortable living environment for people. The carpets producedby machines improve the production efficiency, reduce the production cost, and make themwidespread. The carpet electric gun is a small electronic product which manufactures thecarpets. It works drove by the power. Because it is small-sized and saves space, a man caneasily operate it. In the survey on domestic carpet electric gun manufacturers, we find thatamong the parts of an electric gun, the control box has the highest percentage of sending backfor repair. It connects the electric gun and the power. The Power MOSFET is a single polarityvoltage control devices, with small driving power and high working frequency. It is suitablefor small electronic products’main switching device, with diode and transistor controlling thepower MOSFET. Cooperated with photoelectric couplers it realizes input/output of electricalisolation, high capacity of turning on/off, without heat-radiating components. Single chipmicrocomputer as the whole circuit control section, through its two pins used to detect workbutton and reset. Because the control box and guns are linked together with long term, thispaper adopted the form of current feedback. The thesis analyzes the cause of breakdown ofpresent control box. According to how the workers produce the carpets, the essay schemes outcorresponding anti-interference control circuit, taking single chip as the core and power fieldeffect transistor as the switches. This control circuit can prolong the life of control box,promote efficiency of electric gun motor and lower the complexity of resetting electric gun towork, which is much easier and convenient for the workers to use the electric gun.
