Abstract

In view of the lack of effective monitoring means and the low utilization rate of seeding Data and information of large-scale corn seeding work in Central Plains, this paper designs the operation quality monitoring system of maize no tillage variable rate fertilization seeder. The system includes seeding quality monitoring subsystem and variable rate fertilization monitoring subsystem. The monitoring subsystem of seeding quality can collect seeding information such as seeding rate statistics and missing seeding rate by STM32 single chip microcomputer. Variable rate fertilization quality monitoring subsystem collects work information such as blockage, fertilizer shortage and fertilization amount by PLC, and realizes variable rate fertilization by PID control servo motor. The experimental results show that the operation quality monitoring system for corn no tillage variable rate fertilization seeder is stable in complex environment. The monitoring accuracy of missed seeding was 97.34%. The relative error of seeding rate is 1.20%. Under different operating speeds, the relative error between the actual and theoretical fertilization was 1.95%. The system effectively improved the quality of corn seeding operation.
