Comme nous le savons tous, Les étiquettes électroniques sont principalement divisées en étiquettes électroniques à haute fréquence, étiquettes électroniques basse fréquence et étiquettes électroniques ultra haute fréquence selon la classification des fréquences. Aujourd'hui, nous voulons principalement comprendre les avantages et les applications des étiquettes électroniques RFID UHF.
1、 Les avantages de l'étiquette RFID UHF;
It can recognize high-speed moving objects and multiple objects at the same time
1. It has strong penetrability and can resist harsh environment.
2. Sécurité, confidentiality is also very strong.
3. It can be reused, and the memory capacity of data is relatively large.
2、 UHF RFID tag standard protocol;
Now the common UHF RFID Air Port protocols in China include international standards, normes nationales, normes de l'industrie, enterprise standards, etc..
The most popular standards are 6C and 6D standards, namely ISO / IEC 18000-6c (63) and ISO / IEC 18000-6d (64). En outre, China’s national standard GB / T 29768-2013 was officially implemented in May 2014
3、 UHF RFID tag frequency band;
The definition and coverage of UHF tag frequency band are different all over the world
1. The frequency bands in China are 840 ~ 844mhz and 920 ~ 924mhz
2. The frequency band of EU is 865mhz ~ 868mhz
3. The Japanese frequency band is between 952mhz and 954mhz.
4. Hong Kong, Thailand and Singapore are 920mhz ~ 925mhz
5. La bande de fréquence des États-Unis, Canada, Porto Rico, Mexico and South America is 902mhz ~ 928mhz
4、 Application of UHF tag;
UHF RFID is widely used in the market, with the advantages of reading multiple tags at one time, long identification distance, fast data transmission speed, high reliability and service life, and being able to withstand outdoor harsh environment. Il peut être utilisé dans la gestion des actifs, Gestion de la ligne de production, gestion de la chaîne d'approvisionnement, entrepôts, anti-counterfeiting traceability of various goods (comme le tabac, alcool, médecine, etc.), vente au détail, vehicle management, etc..
