Research on Aptitude Watch and Control System for Precision Seeder

An aptitude watch and control system based on high capability C8051F020 MCU and used for matched with precision unite furrow and seed machine has been developed. This system can watch the all process of seeding, set the speed of seeding, carry out seeding according to set parameters, and measure the parameters of seeding. Furthermore, this system not only can show the set parameters of dropped grains per meter, the real number of dropped grain per meter,the speed of seeding, the sown area,the seed quantity and the seeding status on real time by using LCD module as the interface between workingman and system but also can protract the corresponding changing curve on the show screen. On the other hand, the system can be used in building web. This paper gives the hardware configure, working theory and software flow of this system.
