This paper have designed a kind of UHF RFID based on ISO/IEC 18000-6B standard and supporting multiple fieldbus. Hardware were mainly introduced from the reader hardware and fieldbus control module circuits, and software were respectively introduced from system master programs and bus receiver and launching system software. With the development of RFID, developing supporting fieldbus UHF RFID has...
In recent years, security risks of equipment are very prominent. In order to ensure normal operations, equipment inspection is required to standardization. Information technology is an important means of ensuring the safe operation of equipment. In this paper, a new equipment inspection system based on Zigbee is presented. This system is composed of data management center, wireless gateway, wireless...
Collision is a familiar problem in an RFID system. How to solve this problem effectively is very important to the whole RFID system. Anti-collision technology is one of the key factors that determine RFID system performance, especially for UHF RFID, multiple object identification depends on anti collision performance, This paper emphatically studies the solution and improvement of anti-collision algorithm...
This paper designed an UHF RFID reader based on the ISO/IEC 18000-6B standard, it describes the hardware design and software design of RFID reader. The hardware includes the RF sending circuit and the RF receiving circuit. Especially in the receiving system, it uses integrated circuit and the direct demodulation signal reception programme to achieve hardware optimized receiver circuit design. Using...
