摘要
开发了一套对射式微波水分检测装置。以STC89C52芯片为主处理器,控制各部件执行顺序。为保证物料装载的一致性,采用光电开关控制装载量;为消除温度影响,实时采集样本料温,建立温度补偿模型;为避免微波产生热效应,采用时序控制采集温度及微波信号,以实现粮食水分的准确测量。经实验验证,物料实际水分与微波检测水分之间的相关系数>0.96,满足实际检测要求。
A set of grain moisture detection device based on incident microwave was designed,and the STC89 C52 chip was used as the main processor to control the execution order of each component.Moreover,the photoelectric switch was used to keep the amount of the loading material in line.In order to eliminate the influence of temperature,it was detected in real time,and the temperature compensation model is established.To avoid the thermal effect of microwave,the sequential control system was applied to collect temperature and microwave signals,ensuring the accurate measurement of grain moisture.The results showed that the correlation coefficient between actual moisture content and microwave moisture content was greater than 0.96,and it could meet the requirements of actual test.
