射频识别与北斗卫星导航系统在物联网中的应用

摘要

物联网是上个世纪末提出的新概念，其发展历史比较短。本文是基于家电物联网项目的技术应用，以三洋荣事达企业的实际物流配送为原型，将无线射频识别（RFID）技术以标签的形式用于对物品进行唯一标识，并采用帧时隙算法解决RFID系统中应答碰撞的问题，保证在读取RFID标签发出的信号时做到既不丢失也不重复。将北斗卫星导航系统用在对在途车辆及货物的跟踪定位上，降低货物丢失的风险，降低产品成本，提高企业利润。%As a new concept supported at the end of last century, internet of things owns a short history. This thesis is based on the internet-of-things project and the logistics and distribution of Royalstar. In the process, the technology of Radio Frequency Identi-fication (RFID) is applied to identify each product. In addition, in order to solve the collision of response in the RFID system, ALO-HA is applied not to miss or repeat the signal from one RFID label. Moreover BeiDou(COMPASS)Navigation Satellite System is ap-plied to locate the trucks and the products on the way timely. So that the risk of losing product is reduced while the expense of each product reduces and the profit of company increases.
