The Study of System of Tracking and Positioning Library Books Based on RFID and ZigBee Technique

摘要

A wireless sensor network monitor system is designed based on CC2520 to solve the problem of confusion existing in management of library books. This method innovativly combines RFID radio frequency technology with ZigBee technology with the goal of tracking and positioning the books wirelessly. The designing principle and hardware structure of the system are introduced in detail in this paper. In order to track the exact position of a certain book the method, i.e. virtual routing tracking algorithms based on RFID network is applied. In addition communication frequency choice, network topological structure and the software design of the system are briefly introduced. This system can expand easily and is open to other areas, which also realized the short distance communication of wirelessness, low power consumption and low cost. At last, the feasibility and stability of the system is verified through experiments.
