针对联合收割机实时监测谷物产量的需要，提出了一种基于称重法的产量测量方法，采用电阻应变式压力传感器对收获谷物进行称重测量，将采集的数据经过放大电路、A/D转换后传送给单片机进行计算处理，根据传感器采集的数据建立回归预测模型计算当前谷物产量。该系统可以对谷物产量进行实时监测并在液晶屏上显示和存储。

To meet the needs of combine-harvester monitoring the grain yield anytime , this paper puts forward a yeild measuring way based on the weighing method .In the design , resistance strain-type pressure sensor gets used to weigh the grain.In the next step, the acquired data will be transferred by the amplifying circuit and A /D.Finally, the data will be sent to the SCM to finish the calculation .According to the data from the sensor , it builds a regression model to calculate the present grain yield .This system could accomplish the real-time monitoring to the grain yield and make the data dis-played and stored on the LCD screen .
