| description | The application discloses a label anti-collision method and an active radio frequency identifying label. The method is applied to the active radio frequency identifying label. The label anti-collision includes steps of S11, sending data information; waiting to receive an answer signal responding to the data information; if the answer signal is not received, entering step S12; S12m detecting a carrier wave; if the carrier wave is detected, entering step S13; S13, delaying the preset time, and detecting the carrier wave again; S14, if the carrier wave is not detected, entering step S11; if the carrier wave is detected, entering the step S13. By comparing with the traditional ALOHA algorithm that the data information is sent after delaying the preset time, it is obvious that the label anti-collision method further reduces the collision ratio of the ALOHA algorithm and improves the communication efficiency since the carrier wave is detected after delaying the preset time, and the data information of the next time |
