摘要:The research aims to design and build a set of intelligent control and precision sowing simulation system for wheat. the researchers attempt to drive feed shaft by DC motor replacing pure mechanical wheel-driven seeding mode, to make up the leakage of seeds and random seeding quantity during sowing. The variation of the motor speed is achieved by adjusting the duty ratio of PWM (pulse width modulation), and the PWM is controlled by stc89c52 MCU timer interrupt method. All the information will be processed in the host control system. After processing the information is real-time displayed by liquid crystal and sent out to the slave control system used to drive the feed shaft by PWM dynamically, to realize intelligent control and achieve drill operation speed change, seeding quantity and spacing in the rows stable. The DC motor used to drive feed shaft is with rated voltage of 12V, and the power is taken from the battery of the tractor. The seed-metering device is designed by the researchers. Simulation tests show that the application of the wheat intelligent control and precision seeding system can meet the requirements of precision sowing.
