【摘要】 通过对电容式谷物水分测量中起关键作用的参数,水分变化引起的频率变化和被测谷物温度对含水量测量精度影响的研究,得出了最优谷物水分测量模型。将模型参数固化到以DSP为核心的系统存储器后,其谷物含水量测量精度高于1%,较现有装置测量精度有较大提高,充分表现出了所设计的模型的合理性。更多还原

【Abstract】 Through the study of the frequency variance caused by water content of grain and the precision influence temperature,which play a key role in the study of capacitor grain moisture measurement,an optimization model was discussed in this paper.After the parameters were stored in the memory of system which the DSP is the core processor,the grain moisture measuring precision reached higher than 1%.Those performances indicated that the precision improved a lot than existing equipments and also showed that the model is reasonable.更多还原
