Abstract
The direct current motor has already got the extensive application in realms, such as metallurgy, mineral mountain, chemical engineering, transportation, machine, spinning and aviation etc. Because science progresses unremittingly, the application of the direct current motor, in the intelligence robot particularly, is more extensive. A speed-adjusted system of DC conctrolled by MCU according the adventage of DC motor such as starting easily, good performance, and strong carrying over.
This design makes use of the place of honor machine that the AT89C51 a machine designed a system with minimum machine to constitute the direct current motive feedback control system, the place of honor's machine tool has outward a pulse signal to count and in fixed time function, can count pulse with the software conversion to become to turn soon, designs 4 keyboarders to connect and the LCD manifestation to connect in a system with minimum machine at the same time. Making use of the AT89C2051 designed from the direct current electrical engineering control electric circuit of a machine realization, namely the direct current motive feedback controls the system of next machine, that next machine tool contain the feedback control function of the direct current electrical engineering. Of the place of honor machine and next machine adopts abreast always the linear way to carry on the conjunction, making control to become very convenient.
This system can carry out the direct current motive of automatic start, auto stop, the speed controls automatically, the direction controls automatically etc. function. The designing to win to make use of the LCD manifestation will specify to turn the number, turn the number physically, revolve the direction, and circulate time etc. the parameter shows to come out.
This system operation is simple and builds the price low, the safe and dependable is high, controlling vivid convenience, have the higher function with again development.
