【摘要】 设计了平行梁冲量式谷物质量流量传感器,以该传感器为核心部件并结合其它传感器构建了测产系统。具体分析了系统的硬件结构设计、软件流程以及相应的算法。针对小麦、水稻两种不同谷物品种,不同联合收获机机型以及不同田间地面状况,于2004年夏秋两季分别在中国科学院栾城农业生态系统实验站和上海五四农场做了精准收获实验。实验结果表明,测产系统可以在正常农田地面状况下可靠地工作, 单产和总产测量误差均小于10％,且对联合收获机机型以及谷物品种不敏感。更多还原

【Abstract】 Based on a new parallel beam impact-based grain mass flow sensor the smart yield monitor was designed. The corresponding hardware structure, software flow and the data processing algorithm were demonstrated in detail. In June and October 2004, with the different type of grain, different type of combine, and different field ground condition, the harvesting experiment had been carried out respectively at Luancheng agricultural ecosystem experiment station of Chinese science academy and the Shanghai Wusi farm. The experimental result shown that the accuracy of this yield monitor was within 10% under the general field ground condition, moreover, the yield monitor is insensitive to the different type of combine and different type of grain.更多还原
