Abstract: For a class of low efficiency of supermarket shopping system,this paper proposes a system for fast shopping methods and security strategy based on Radio Frequency Identification(RFID) technology.For fast,large scan shopping system,this paper presents an improved binary search anti-collision algorithm to achieve a rapid and complete information collection on the expectation goods and to analyse generating conditions of redundancy identification and dead identification,for universal situation,which can improve the system’s accuracy and reliability.On this basis,the system increases the security mechanisms,checkout goods can be scan in the designated area,and the staff can be notified.In addition,for different conditions,two flexible ways of purchase are designed,which are easy for service management.Experimental results show the smart system not only can express check-out for buying things,but also restrains the errors happened in the buying course.

Key words: Radio Frequency Identification(RFID), express checkout, express storage, anti-collision algorithm, security strategy

摘要： 针对超市购物系统运行效率过低的问题,提出基于射频识别技术的快速购物方法和防盗策略系统。对于需要进行快速、大量扫描的购物系统,给出一种改进的二进制搜索防碰撞算法,实现对期望货品的完全信息快速采集,并分析冗余识别和死角识别的产生条件,提高该系统的准确性和可靠性。在此基础上,增加防盗环节,在指定区域扫描未经过结账处理的货品,并及时通知相关人员。根据不同货品条件,设计2种灵活的进货方式,便于超市服务人员进行管理。实验结果表明,该智能购物系统能够快速准确地对消费者所购商品进行结账,同时可以较好地抑制系统运行过程中可能出现的数据误差。
