摘要：
Facing the problem of existing maize precision planting control system cannot quickly drive the seed sowing of multiple types corn precision seed meters, an on-site seeding rate calibration system was designed based on the controller area network (CAN) bus motor-driving corn planting technology. From the corresponding relationship between the motor control signal and the rotate speed of seed plate, the system got the seed meter driving curve in the filed using piecewise linear interpolation to realize the seeding rate control. Taking a domestic corn air-suction seed meter and a corn finger pick-up seed meter as the test objects, the speed control performance of seed plate in simulative travel speed was respectively evaluated. In the experiment of rotate speed control performance of corn air-suction seed meter, the seed spacing was set to be 25 cm and the travel speed was set to be 3~12 km/h with increment of 3 km/h, the greatest response time was 0. 80 s, the biggest steady-state error was 0.81 r/min and the lowest accuracy of seed plate rotate speed control was 97.42%. In the experiment of rotate speed control performance of corn finer pick-up seed meter, the seed spacing was set to be 20 cm, 25 cm and 32 cm and the travel speed was set to be 4~9 km/h with increment of 1 km/h, the results showed that the average response time of the whole rotate speed of seed meter was 1.09 s with standard deviation of 0.26 s; the average steady-state error of the whole experiments was 0.38 r/min with standard deviation of 0.23 r/min; the average accuracy of rotate speed control of the whole experiments was 98. 30% with standard deviation of 1.01%. Compared the seed plate rotate speed control system with the sectional proportion integration differentiation (PID) method, the system supported seed plate rotate speed on-line calibration had a better adaptability, the average response time was decreased by 0.51 s, the average steady-state error was increased by 0.16 r/min and the average accuracy of rotate speed control was decreased by 0.63 percentage points. The planting uniformity experiment in field was performed, taking the finger pick-up seed meter as the material. In the experiment of planting uniformity in field, the seed spacing was set to be 20 cm and the travel speed was 4~7 km/h with increment of 1 km/h, the results showed that the quality of feed index was greater or equal to 84.26%, and the coefficient of variation was less than or equal to 18.29%. The above results indicated that the system can precisely control the rotate speed of motor driving planting through the way of calibrating the planting rotate speed control curve of corn precision seed meter on site with high accuracy. © 2020, Chinese Society of Agricultural Machinery.
