Yield Maps are a basic information source for site-specific farming. For sugar beet they are not available as in-situ measurements. This gap of information can be filled with Earth Observation (EO) ...
双板差分冲量式谷物流量传感器设计（Design of a Dual-plate Differential Impact-based Yield Sensor）
谷物 流量传感器 冲量式
2009/5/22
设计了一种双板冲量式谷物流量传感器及其差分消振电路，以消除车身振动对测产精度的影响。振动试验表明，在没有谷物输入时联合收获机车身振动导致前后2个检测板产生的2个振动信号是一对共模信号，可通过电路差分的方法消除；差分后传感器的输出电压的信噪比由2.5dB提高到62dB。在零喂入量情况下，振动产生的零点误差小于0.01g/s；在联合收获机正常作业的喂入量范围内（0.5～2kg/s），实验室测量误差小于...
