Applied research of RFID technology in express logistics industry

In order to improve the efficiency of express logistics enterprises, a mail automatic identification system with low power consumption is designed based on radio frequency identification technology. Considering the characteristics of express logistics enterprises, an improved anti-collision algorithm on the basis of binary search tree is introduced. The algorithm can modify the search prefix by a matrix to reduce the number of search. MATLAB simulation results show that the algorithm can effectively enhance the efficiency of tag identification and reduce the amount of data transmission compared with binary search algorithm and binary collision algorithm.
