Application research of contactless proximity sensor based on infrared pulse

传统厨电多注重于基础功能的提升,但随着智能技术的迅速普及,厨电中的智能元素也越来越多。通过将基于红外脉冲的非接触式接近传感器应用于厨电,实现用户与家电之间的智能交互。首先对该传感器的工作原理进行分析,再结合实际使用场景设计出工作电路,最后试验研究验证了该传感器的可行性,并对照度、透射油墨、反射颜色、感应区域等影响因素进行试验分析,结果表明照度对传感器应用无影响;只有配合红外透射油墨使用才能保证传感器正常工作;障碍物颜色会影响传感器感应距离;根据用户使用习惯对感应区域进行设计,并能保证较高的感应成功率。

Traditional appliances of kitchen pay more attention to the improvement of basic functions,but with the rapid popularization of intelligent technology,there are more and more intelligent elements in the appliances of kitchen.The non-contact proximity sensor based on infrared pulse is applied to kitchen electricity,the intelligent interaction between users and appliances is realized.Firstly,the working principle of the sensor is analyzed,then the working circuit is designed according to the actual scenario.Finally,the feasibility of the sensor is verified by test and research.The influence factors of illumination,transmission ink,reflection color and sensing area were analyzed,results show that the illumination has no effect on the application of the sensor;the sensor works normally only with infrared ink,the color of the obstacle will affect the sensing distance.According to the usage habit of user,the induction area is designed and the induction success rate is high.
