摘　　要：设计了一种基于射频识别(RFID)技术的桥架型起重机大车与小车的高精度定位系统。该系统通过在大车和小车运行轨道上每隔50 cm布设RFID标签(IC卡),并在起重机上安装高灵敏度RFID读卡器,利用读卡器读取标签的信号强度及存在性,结合相应的定位算法,实现了误差不超过20 cm的定位。阐述了系统架构、硬件选型、软件设计、定位算法、实验验证及结果分析,并探讨了该系统的应用前景及未来优化方向。This paper presents the design of a high-precision positioning system for the cart and trolley of a bridge-type crane based on radio frequency identification(RFID)technology.RFID tags(IC cards)are deployed at 50 cm intervals along the running tracks of the cart and trolley,with a high-sensitivity RFID reader installed on the crane.By analyzing the signal strength and presence of the tags through the reader and integrating a corresponding positioning algorithm,the system achieves positioning accuracy with an error margin of less than 20 cm.The system architecture,hardware selection,software design,positioning algorithm,experimental validation,and result analysis are elaborated,and the application prospects and future optimization directions of the system are discussed.
