Design and Experiment of Electric Drive Wheat Planter Monitoring System Based on Beidou Speed Measurement
The system is based on Beidou speed monitoring system,which can monitor wheat seed leakage through capaci-tance detection and fertilizer blockage in the fertilizer discharge pipe through infrared photoelectric detection.In field ex-periments,the performance of the seeder equipped with the system was good,with an accuracy rate of over 91%for so-wing leakage detection,over 95%for fertiliser blockage detection.The average sowing pass rate was more than 94.6%,the missed sowing index was less than 2.8%,the reseeding index was less than 3%and the coefficient of variation of uni-formity was less than 3.5%,which could meet the requirements of precision sowing of wheat.
