|
摘要
为提高农业机械信息化程度,实现施肥作业机械肥箱料位在线检测,根据颗粒化肥与空气介电常数的差异性,设计了基于电容法的施肥作业机械肥箱化肥料位在线检测传感器。建立了颗粒化肥(尿素)与电容输出值之间的关系模型,并对模型进行了验证。结果表明:施肥作业机械肥箱料位在线检测传感器对于肥箱料位的检测最大误差率为1.4%,能够精准地对肥箱料位情况进行在线检测,为施肥作业机械肥箱料位在线检测提供了有效途径,对提高农机信息化水平有具重要意义。
In order to improve the information level of agricultural machinery and realize the on-line detection of fertilizer box material level in fertilizing operation machinery,according to the difference of permittivity between granular fertilizer and air,a sensor based on capacitive method is designed for the on-line detection of fertilizer material level in machinery fertilizer box of fertilizing operation. The relationship between granular fertilizer( urea) and capacitance output value was established and verified. The results show that the maximum error rate of the fertilizer box material level detection sensor is 1.4,and the sensor can accurately detect the fertilizer box material level on line. Replacing the manual detection with the electronic detection not only improves the diversity of the agricultural online detection technology but also raises the degree of the online agriculture machinery information detection. It is making a significant contribution to reducing agriculture production cost,diminishing safety risks and raising agriculture machinery infornationization level. Capacitive fertilizer material level detection sensor is mechanical fertilizer for fertilizing operation On-line material level detection provides an effective way to improve the information level of agricultural machinery.
