The characteristics of the electronic tag system is a non-contact identification using radio frequency technology , wireless communication , it can simultaneously identify multiple electronic tags and electronic tags of the high - speed movement . Without exposed electrical contacts to encapsulate different application requirements , and can resist harsh environments . Due to its advantages in foreign electronic tags has been widely used in many fields in China are also being popular . Therefore , the research, development and application of electronic tagging system has great significance . With reference to the international standard ISO/IEC14443 , electronic tag antenna on the basis of in -depth understanding of the principles of the electronic tag system , the structure of the chip of the electronic tag and the instruction , the principle of the coupling of the antenna of the electronic tag , the RF module structure and instruction completed its read Write the design . Main work and content of the papers : 1 , electronic labeling system principle introduced , including: electronic label system constitutes the main technical parameters , the electronic tag system RF communication technology , data modulation and demodulation , energy transmission , system the channel coding and access control technology , information security technology ; 2, the electronic tag antenna design , using and Mifare similar structure of the chip , operation instruction and the storage area ; electronic tag antenna of the design , including the principles of the antenna coupler and antenna miniature design , plate making , tapeout , experiment and test ; electronic tag reader design , the main contents include : MCU , RF modules , power supply circuit , EEPROM , time circuits , LCD display circuit , RS232 interface circuit and SAM card interfaces circuit structure and function ; electronic tag antenna plate making and production of samples , and manufacture of a complete electronic tags have a good read and write performance , tested printed circuit board ; electronic tag reader has drawn PROTEL software and made ??a prototype , the initial commissioning has been through .
