摘　　要：为了使目前轨道车辆运行效率提高,采用射频识别RFID技术对轨道车辆的物理位置进行实时监测的方法,提出一种利用RFID技术对轨道车辆进行实时定位的系统,并介绍该实时定位系统的设计方案、组成及工作原理,主要包括RFID标签安置、RFID读写及与后台服务器通信等技术。系统运行性能结果表明利用RFID技术对轨道车辆进行实时定位具有精度高、环境适用性强等优点,在地铁和企业厂段的轨道车辆实时定位中具有良好的应用前景。To improve operating efficiency of the available rall vehicles, the radio frequency identification （RFID） technolo- gy was adopted to conduct real-time monitoring for the physical position of rail vehicles. The RFID-based real-time positioning system for rail vehicles is proposed. The design scheme, constitution and operational principles of the system are introduced. RFID label placement, RFID read-write and technology communicating with the backend servers are described emphatically. The operating result of this system indicates the RFID-based real-time positioning system for rail vehicles has the advantages of high precision and strong adaptability and can improve the positioning efficiency. A conclusion that the technology has a brilliant prospect for being applied to real-time positioning of rail vehicles on subways and railways inside enterprises has been obtained.
