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构建了测产系统。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。A new parallel beam impact-based yield monitor was designed, and in June and uctooer 2004, with the different type of grains, different type of combines, and different field ground conditions, the harvesting experiments were carried out respectively at Luancheng agricultural ecosystem experimental station of Chinese Academy of Sciences and on Wusi Farm in Shanghai. The experimental results showed 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 combines and different type of grains.
