Abstract

Traditional yield monitoring in breeding plots is manually conducted, which is labour-intensive and inefficient. To address this issue, an airborne yield monitoring system that collects yield information during the harvesting in plots was designed. The system consists of a host computer and a slave computer. The slave computer used weight and moisture sensors to collect yield information of crops. The host computer used LabVIEW software to design a data management platform that displays and saves yield information and draws yield distribution maps for data visualization. The host and slave computers communicate data through 4G networks. By designing anti-interference measures, the dynamic experimental results showed that the average errors between the measured weight and moisture content by the system were 1.330% and 2.800%, which met the accuracy requirements of yield testing in plot breeding. The results indicated that the structure of the system is reasonable and can provide reliable yield monitoring tools for researchers in breeding plots.

传统的小区育种产量测试通过人工抽检完成，该方法劳动强度大、工作效率低。针对此问题，本文设计了一种在小区收获过程中采集产量信息的机载测产系统，该系统分为上位机和下位机两部分。下位机使用称重传感器与水分传感器采集小区作物的产量信息；上位机使用LabVIEW软件设计数据管理平台，对产量信息进行显示与保存，并绘制产量分布图，实现数据可视化；上下位机通过4G网络进行数据通信。通过对收割机进行抗干扰设计，动态实验结果显示测产系统重量与含水率测试的平均误差为1.330%和2.800%，均满足育种试验产量测试的精度要求。结果表明该系统结构设计合理，可以为小区育种科研工作者提供可靠的测产工具。
