摘要
冲量式产量传感器是精准收获过程中谷物产量在线测量的主要装置。但由于其自身固有特点,测量的数据误差较大。本文对此进行了研究并研制了相关处理电路,取得了较好的效果。试验表明,处理后系统的实际测产误差小于6%。
The impulse yield monitor is a main device for corn yield on-line measuring. However, the measuring errors are rather large due to its natural feature. In this paper, we investigated it and developed corresponding processing circuit, which acquires better results. The test results shown that the measuring errors of this improved system are within ±6%.
