| 摘 要： | 高速精密播种作业是大豆、玉米等作物播种的主要发展方向之一。该文针对高速精密播种作业中气吸式排种器,设计了排种器吸种状态检测系统(seed disc suction performance detection system,SDSPS),该系统采用凹形光电传感器采集排种盘吸种信息、应用光电旋转编码器采集排种轴转动角度等信息,通过对光电传感器的输出信号和光电编码器脉冲信号进行处理,得到排种盘每个吸孔的吸种情况,从而进一步获取整个排种器的工作状况。与排种器试验台常用的图像处理检测系统(seeding detecting system based on image processing,SDSIP)在6组作业条件下进行了试验台对比试验,并单独进行了检测单个吸孔吸种量可行性试验。试验通过F检验和T检验(α=0.05)得出2种系统测量值总体方差相同和均值一致。精度分析结果表明SDSPS相比于SDSIP的最大相对误差为0.31%,系统稳定性分析结果表明SDSPS与SDSIP的波动幅值比较接近,两者的最大相对偏差值都不超过1%,SDSPS检测单个吸孔吸种量的最大相对误差为16.67%。通过田间试验验证,SDSPS对于漏吸种量和多吸种量,检测系统检测值与实际值相对误差平均值分别为3.87%和8.42%。SDSPS能有效的进行排种盘吸种性能检测,对单个吸孔吸种量的检测也具有较高的可信度,可以为气吸式排种器性能检测与改进提供技术支撑。
