Abstract :
In order to improve identification speed of address tags of RTLS and overcome the low-power problem, a high identification speed and low-power power card reader applied in RTLS (Real Time Location System) is designed. The reader with wireless identification based on RF technology is researched. An improved anti-collision algorithm (Optimized Dynamic Framed Slotted ALOHA) is proposed to improve the identification efficiency and minish collisions among tags. MSP430 is used to be control core and nRF2401 is selected as the wireless identification module to operate reading and writing address cards. This instrument can be used in vaccine tracking and ID identification, which has wide applications and is worth to be extended.
