射频识别系统一般由三部分组成:电子标签(射频卡)、读取器和天线。正确快速的识别电子标签的标签号码,是门禁系统发挥其功能的先决条件。以无源低频射频卡识别模块SMC51489为例,介绍了对射频卡信息读取的原理和方法,并给出了相应的软件编程。实验证明该模块不仅具有较大的读卡距离,而且工作可靠。
Abstract:
 A typical radio frequency identification (RFID) system consists of three parts: tag, reader and antenna.To identify the content of the tag correctly and quickly is the primary condition of the access control system to display its function.Taking the passive low frequency RFID module SMC51489 as an example,the principle and the method to acquire the content of the tag is introduced,and the corre?sponding software is given.The experiment result show that the module not only has big access distance, but works reliably.
