基于RFID技术的智能轨道交通票务系统设计研究

随着城市轨道交通客流量的增加，轨道交通承载的交通压力越来越大，如今迅猛发展的物联网技术可为解决轨道交通出行提供新思路，现提出基于射频识别（radio frequency identification，RFID）技术的智能轨道交通票务系统设计研究。本系统主要由嵌有RFID标签的交通卡、进站系统、里程记录系统和出站系统构成，与数据库大数据完美结合可以为乘客乘车提供便利，同时完善轨道交通收费的合理性。为了提高RFID阅读器识别标签的效率提出一种基于动态帧时隙的防碰撞算法，通过动态调整帧长达到标签被快速识别的效果，来提高整个城轨交通系统的效率，缓解人们的出行压力。

Design and Investigation of Intelligent Rail Transit TicketingSystem Based on RFID Technology

Currently, traffic pressure is increasing due to the increase of urban rail transit passenger volume. The rapid development of the Internet of Things technology can provide a new method of solving the problem of rail transit. This paper proposes the design of an intelligent rail transit ticketing system based on the RFID technology. This system is mainly composed of labels embedded with Radio Frequency Identification (RFID), an entry system, a mileage recording system, and an outbound system, which can provide convenience for passengers and improve the rationality of charge. In addition, this paper presents an anti-collision algorithm based on a dynamic frame slot to improve the efficiency of tag identification. A tag can be identified effectively by dynamically adjusting frame length to improve the efficiency of the entire rail system and alleviate traffic pressure.
