智能公共交通物联网管控终端的设计

本文就当今公共交通系统智能化方向发展的需求提出了一种基于RFID的智能公共交通物联网系统的总体方案，重点介绍了该系统管控终端的软硬件实现方法。系统的管控终端采用低成本，低功耗的设计，能够通过RFID标签有效地采集系统中的公共交通工具信息以及用户卡信息。管控终端向用户（乘客）提供了便捷的非接触式读卡器和友好的人机交互界面，用户可以通过智能公交卡方便地乘车或是租借公共自行车。借助该系统，运营者可以建立基于销售终端安全模块（PSAM）的智能卡预付费消费系统，同时可以对公共交通资源进行有效地管理与控制。

The Design of the Management Control Terminal in Intelligent Public Transportation Internet of Things

Today＇s public transportation system is tending to become more intelligent, this paper has put forward a scheme of intelligent public transportation Internet of Things based on RFID, and mainly introduces the hardware and software implementation of management control terminal. This terminal with low cost, low power design is able to effectively collect vehicle information as well as user information through the RFID tags. It provides the user （passenger） with a contactless smart card reader and a friendly man-machine interface, the user hence is able to take transportation or borrow a public bicycle only with a smart card for public transportation. With help of this system, operators are able to establish a smart card prepaid fee deduction system based on PSAM （Purchase Secure Access Module）, introduces an effective way of control and management of the public transport resources.
