Design of real-time inspection and aeronautical instrument displaying system for areomotor revving

Abstract

In this paper, a kind of real-time inspection and aeronautical instrument displaying system of areomotor revving based on single chip technical is introduced. The system is mainly consisted of signal transformation, single chip microcomputer AT89C51 and step motor's drive electric circuit. Experimental results show that when the intial signal frequency inputted, the aeronautical instrument starts to turn to the corresponding angle position; when the signal frequency constantly changing, the aeronautical instrument turns to move corresponding angle; The accuracy comes to control request while changing frequency; The system is small in size and simple in operation and high steady.
