| Abstract: | 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. |
