摘要
如果将无线电射频信号进行整流,通过整流电容可以储电来替代电池,人们对无源RFID系统的基本原理也能够理解和接受。更进一步,无源RFID系统尚可以实现多个电子标签的同时识别。如果没有通信协议的概念相辅助的话,人们对此依然会感到颇为费解。
If people rectified RFID signals, stored electricity by rectifier and capacitance for replacing the traditional batteries, people could understand and accept the fundamental principle of the passive RFID system. Furthermore, the passive RFID system could realize simultaneous identification of multi-tags in the system. Without the help of communication protocol, people still feel puzzled.
