摘要
针对当前小麦播种机智能化程度低、播种作业时种子漏播肥料堵塞导致缺苗断垄现象产生的问题,设计了一款基于北斗测速的电驱式小麦播种机监控系统.通过电容检测可以实时监测小麦种子漏播情况,通过光电检测可以实时监控排肥管内肥料堵塞情况;北斗卫星实时定位并计算出播种机的前进速度,控制器根据播种机前进速度实时调节播种施肥电机转速,实现种子漏播、肥料堵塞报警和精量播种施肥的目的.在田间试验中,装载监控系统的播种机各项性能表现良好,漏播检测准确率 91%以上,肥料堵塞检测准确率 95%以上,播种合格率平均值大于 94.6%,漏播指数小于 2.8%,重播指数小于 3%,均匀度变异系数小于 3.5%,能够满足小麦精量播种的要求.
Abstract
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.
