摘要
RFID是一种非接触式的自动识别技术,广泛运用于生产制造、物流管理和公共安全等各个领域,但在实际应用中,RFID系统还面临着许多亟需解决的问题,例如标准不统一、安全与隐私、多样性和复杂性以及数据碰撞等,特别是数据碰撞问题将直接导致标签识别效率的降低和资源的浪费。本文对现有的各种数据防碰撞技术进行归纳总结,并指出其优缺点和研究的进展情况,同时给出数据防碰撞技术的研究方向。
RFID is one kind of contactless automatic recognition technologies,used widely in manufacturing,logistic management,and public security fields and so on.But in practical application RFID system still has a lot of problems to solve.Problems of not unified of standards,hidden danger,diversity and complexity,and data collision.Especially,the data concllsion will directly lead to efficiency reduce of label identifcation and waste of resources.Not only the paper summarizes all kinds of data anti-collision technology,but also shows its advantages of disadvantages and progress and direction of research.
