智能电子标签的研究与应用

Research and Application of the Intelligence Electronics Label

以专用芯片BL75R02的应用为目的,介绍了以芯片BL75R02为核心的智能电子标签系统的工作原理,并从芯片的内部结构作为切入点,介绍了智能电子标签芯片的内部结构原理图,重点介绍了在通讯过程中的负载调制原理和多片并发时,利用标签序列号惟一的特点,采用“时分多址”通讯方式,达到上行端读卡机在进行多片搜索时抗冲突机制的实现,并从不同侧面介绍了他的应用。

This text takes the application of appropriation chip BL75R02 as a purpose,introduces the intelligenee electronits＇ work principle of the label system with BL75R02, and from the chip of internal structure conduct and actions correspond a point,introdues the intelligence electronics＇ internal structure principle of the label chip diagram, the point introduces at the load in the communication process make principle and many slices to erupt,makes use of the label sequence number is unique characteristics,adopts＂hour divide many address＂communication method,attain north bound to carry to read the card machine at carry on many slices search the anti -conflict mechanism of realization,and never introducs its application with on the side.
