Abstract
Zigbee technology and RFID technology are combined to design the system that can do real-time positioning and tracking on foreign visitors. The system locates and identifies the visitors who wear RFID card via locater and the locater transmits the ID information of RFID card and position information to the coordinator through Zigbee network and then the coordinator will pass the data after redundancy processing to the monitoring center via Ethernet. This system has advantages in low power consumption, wide deployment range, stable signal transmission and good recognization ability and it is applicable to important places such as high-grade residential area, park, warehouse and research institute, etc.
