碾米机性能在线监测装置的设计与研究

The study and design of on-line monitoring devicefor the performance of rice mill

摘要:

传统碾米机靠操作员视觉感官来判断碾米性能,不能实现碾米机的智能自检,其识别精准度差。针对传统碾米机识别精度和智能化程度低等问题,设计了光电监测碾米机性能的在线监测系统,提出了以一种低廉价格芯片STC89C52为微处理器,以硅光电池作为光电传感器对物料品质进行信号采集。工作过程中能周期性计算碾米机碾米性能,根据其效率为碾米机的转速、碾白间隙、进出口流量等提供调整策略。经试验分析,该系统识别准确率可达99.5%以上,同时也为粮食品质检测的数字化、智能化提供了一种新方法。

Abstract:

Traditional rice milling machine operator judge the milling performance by visual sense, can't realize the intelligent self-checking. What’s more, it’s accuracy is poor. Aiming at the low identification precision and intelligent degree of traditional rice mill, a photoelectric monitoring of on-line monitoring system for the performance of rice mill is designed, cheap chip STC89C52 as the microprocessor, and silicon photocell as photoelectric sensor for signal acquisition. This system can periodically calculate performance of rice mill during work, provide the adjust strategy for motor speed, whitening gap, Import and export flowing. Through experimental analysis, the system identification accuracy can reach above 99.5%. At the same time, it provide a new method for digital and intellegent in food quality testing.
