摘  要:
设计了一种用于实时切种式甘蔗种植机的漏播监测与标记系统,采用光幕传感器监测蔗种下落情况,漏播发生时漏播标记装置用石灰在漏播的蔗垄旁边标记出漏播位置。该系统在室内试验台及田间种植机上进行了试验。结果表明:系统监测到的蔗种种距与人工测量种距回归分析的决定系数R2为0.991。田间试验中漏播标记的起点与实际漏播起点之间距离偏差Qp的均值为-83 mm,标准差为216.1 mm。相应的漏播终点偏差Zp的均值为-63 mm,标准差为155.6 mm。试验表明,该系统标记的漏播位置可以为人工补种提供可靠依据。

摘  要:
A sowing leakage monitoring and marking system for sugarcane planter was designed.Light curtain sensor was used to monitor sowing leakage.When sowing leakage was detected,marking device marked the position of leakage in the field with lime stone powder.Experiments were conducted respectively on test bench in laboratory and on planter in field.The results showed that the regression coefficient R2 was 0.991 between monitoring system and manual measurement.In field experiments,the mean of the error(Qp) between marked point and the position real happed in the starting point of sowing leakage was-83 mm.The mean of that error(Zp) in the terminal point of sowing leakage was-63 mm.The standard deviation of Qp and Zp were 216.1 mm and 155.6 mm,respectively.The sowing leakage position marked by system could be used for artificial reseeding.
