Design of RFID Active Tag System Based on MSP430

摘要：

Saving power and extending identification distance are important problems in portables. This paper presents a system on chip for radio frequency identification (RFID) active tag to extend the identification distance and battery life. It uses hardware and software to execute the checking, identifying and real time anti-collision. RF module and active tag system have been completed. Methods for low power consumption and a simple practical adjusting approach for RF module are introduced. The proposed system has advantages such as simple structure, low cost, and low energy electron diffraction. This system is successfully used in 433/868/915 MHz RFID. When TX power is adjusted by the software, the identification distance is between 80meters and 120meters.
