【摘要】：在货运铁路中平面调车业务是最为重要的环节之一。编组站内的业务效率直接影响到整条铁路线的运转。在列车编组站内车厢的位置信息的获取是保证编组站的良好运转的基础数据,传统方式进行的信息采集不仅效率低而且准确性存在隐患。为了有效避免这些问题,本设计中利用RFID技术开发了一套超低功耗的唤醒式半主动电子标签系统,用来进行编组站内车厢位置信息的采集并传输至站内的综合信息服务器,以便管理人员对车厢位置进行监管。针对车载的电子标签的安装读取方式以及标签的较长的使用生命周期的特点,设计出一种基于可被低频信号远程唤醒的有源电子标签及阅读器系统,同时考虑到其阅读特点而设计了一套数据传输的防碰撞算法。此系统能够完成可靠的车厢信息获取,最后通过系统测试,本设计满足需求达到了50米的唤醒距离,并在标签中实现了2048比特信息的存储,能够达到超过八年的使用寿命。
[Abstract]:Plane shunting is one of the most important links in freight railway. The operational efficiency in the marshalling yard directly affects the operation of the whole railway line. Obtaining the position information of the train compartment in the train marshalling station is the basic data to ensure the good operation of the marshalling yard. The traditional way of collecting information is not only inefficient but also has hidden trouble of accuracy. In order to avoid these problems effectively, this design uses RFID technology to develop a set of ultra-low power wake-up semi-active electronic tag system, which is used to collect and transmit the position information of compartments in the marshalling station to the comprehensive information server in the station. In order for the management to monitor the location of the carriage. According to the characteristics of the on-board electronic tag installation and reading mode and the long service life cycle of the tag, an active electronic tag and reader system based on the remote wake-up of low frequency signal is designed. At the same time, a set of anti-collision algorithm for data transmission is designed considering its reading characteristics. The system can obtain the reliable information of the car. Finally, through the system test, the design meets the requirement of 50 meters wake-up distance, and realizes the storage of 2048 bits of information in the label, and can achieve more than eight years of service life.
