The Research for the Grain-Flow-Measurement System on Real Time Based γ-ray Sensor in Laboratory

根据精细农业研究的实际要求,对基于γ射线衰减原理的谷物流量测量方法进行了试验研究,设计了一套联合收割机的谷物流量实时测量试验装置,该装置由联合收割机谷物流量动态模拟实验台、γ射线源和γ射线探测器以及计算机数据采集与处理系统三部分组成。试验结果表明,这种测量系统测量误差可达到±2%。

Precision farming technology needs yield monitor to get yield map. In this paper, a grain - flow - measurement system using the principle of the absorption of γ - rays by grains for combine harvesters was developed in laboratory and it was comprised of a dynamic simulation testing equipment,γ - ray sensor, data acquiring and processing system. The test results show that measurement errors of this system are within ±2%.
