摘　　要：提出了一种基于低成本无线射频识别RFID的局域定位系统设计方法,介绍了系统主要硬件模块的结构和接口设计。针对RFID多标签信号碰撞的问题,采用序列号对时隙数运算的排序算法实现了多标签防碰撞策略。介绍了RFID局域定位系统的定位工作原理及定位算法的设计和实现。实验测试表明,该系统能够通过多标签信号的识别有效实现无线局域定位的功能。A kind of lower cost RFID （Radio Frequency Identification） regional positioning system based in this paper. The structure of main hardware modules and interfaces are introduced. For the problem of signal collision of RFID multi-tags, the strategy of anti-collision for multi-tags is realized by the sorting algorithm based on time slot number calculated by serial number. The operational principle of poisoning system and the implementation of positioning algorithm are introduced also. The experiment illustrates that the system can be well applied in wireless regional positioning by identifying the multi-tags.
