Multi-card recognition is an important part of UHF RFID system

and its recognition effect directly affects the ability of system identification. With the development of Internet of Things

multi-card recognition in most UHF radio frequency identification systems is through system and Intelligent coding technology to achieve

through the existing radio frequency identification of security technology and research

and low-power ultra-high frequency electronic tags for hardware and software design

and complete the antenna and RF circuit and label manufacturing process

In order to achieve ultra-high frequency radio frequency identification system in the multi-card recognition. However

this method has the problem of complicated calculation and difficult to be widely used.In this paper

a multi-card identification method based on multi-server system is proposed. The high frequency radio frequency identification system is analyzed and the energy in the UHF RFID system is studied. And data transmission mode

so as to complete the ultra-high frequency radio frequency identification system anti-collision analysis

on the basis of the establishment of multi-server system model

and the design of the Internet environment UHF radio frequency identification system packet encryption algorithm

Identify the conflict in the system

complete the anti-collision analysis

and finally through the recognition system to identify the card selection

complete the Internet environment under the ultra-high frequency radio frequency identification system in multi-card recognition. Experiments show that the proposed method can improve the storage capacity of the system

realize the long distance barrier reading

has a wide range of use

good security and other advantages

and has good use value.
