研究目的
To develop a portable wireless RFID reader/router for RFID-WSN hybrid system, which has long identification distance, low cost, high flexibility, scalability, and a good interactive interface.
研究成果
The implemented RFID reader/router realizes bidirectional transmission of communication data and makes system networking more flexible. It overcomes many shortcomings of the traditional RFID reader, such as short distance, poor anti-interference, and susceptibility to environmental impacts. The system has a high stability, a long identification distance, an applicable flexibility, and a good scalability.
研究不足
The system's performance is tested in specific environments (indoor and outdoor), and the maximum distance for tag reading is limited to 10 cm. The packet loss rate increases with the transmission distance.
1：Experimental Design and Method Selection:
The design combines RFID technology with ZigBee technology to create a hybrid system. CC2530 is used as the microcontroller and RF module for ZigBee wireless communication, and MF RC522 is used as the reader RF chip.
2：Sample Selection and Data Sources:
The system uses RFID tags and WSN sensor nodes as end nodes to cover the whole industrial or service area.
3：List of Experimental Equipment and Materials:
CC2530 low-power RF chip, MF RC522 RF chip, M1 cards produced by Philips, and other components for circuit design.
4：Experimental Procedures and Operational Workflow:
The RFID reader/router is designed to obtain information from both RFID tags and WSN sensor nodes and transmit the information through the WSN to the PC server. The system's performance is tested in both indoor and outdoor environments.
5：Data Analysis Methods:
The reliability of the communication system is tested by calculating the packet loss rate under different transmission distances.
