摘要
针对衣柜中的衣物难以寻找以及衣物管理效率低下的问题,设计了一款基于RFID技术的智能衣柜系统。该系统采用了FPGA平台和RFID技术,主要由RFID阅读器、电子标签、FPGA模块和显示模块组成,相应的电子标签固定在衣物上,RFID阅读器作为发射和接收高频信号的节点,FPGA模块根据RFID测得的相位差来计算相隔的距离,进而确定电子标签的距离,并将测得的距离转换成电子标签在衣柜内的区域,显示在液晶屏上。实验验证表明,该系统能较好地完成定位测距功能,精度可达到厘米级,可以满足智能衣柜寻找衣物的需求。
Aiming at the problems of difficult to find clothes in the wardrobe and low efficiency of clothing management,this paper designs an intelligent wardrobe system based on RFID technology. The system mainly adopts FPGA platform and RFID technology,which is mainly composed of RFID reader,electronic tags,FPGA module and display module. The corresponding electronic tags are fixed on the clothes. The RFID reader is used as the node to transmit and receive high-frequency signals. The FPGA module calculates the distance according to the phase difference measured by RFID and determines the distance of the electronic tag,the measured distance is converted into the area in the wardrobe where the electronic label is located and displayed on the LCD screen. The experimental results show that the system can well complete the positioning and ranging function,and the accuracy can reach the centimeter level,which can meet the needs of finding clothes in the intelligent wardrobe.
