| Abstract: | In order to improve the work property and automation level of the drill,a kind of automatic control device used in seeding of drill was designed.This paper reported the automatic monitoring equipment of working speed of seeder.In this sensing system,the actual moving speed of the seeder can be converted into pulse signal by a kind of photo-electric sensor,then the pulse signal is inputted into single chip microcomputer for reasoning and finally displaying the speed value of the seeder.According to the working principle of this device,adopting assembly language and modularizing method in programming,aset of software program that can automatically monitor the speed of the drill was developed.The test result showed the hardware system that constituted by MCS-51 single chip microcomputer and sensor circuit could determine and show the real-time speed of the seeder. |
