Abstract

The invention provides a compatible protocol radio frequency identification method and device. The method comprises the following steps: determining a first identification tag in a read-write range through inventory query; sending a first request for confirming communication to the first identification tag and determining first sending time; receiving a first feedback of the first identification tag in response to the first request and determining a second time of receiving; determining a difference value between the second time and the first time, completing radio frequency identification according to a GB / T29768-2013 protocol channel when the difference value is smaller than a first threshold value, and completing radio frequency identification according to a motor vehicle electronic identification protocol channel when the difference value exceeds the first threshold value. The method can be compatible with radio frequency identification of two protocols of GB / T29768-2013 and the electronic identification of the motor vehicle at the same time, the application compatibility is improved, and the implementation cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a radio frequency identification method and device compatible with protocols. Background technique [0002] Radio frequency identification is a non-contact data communication method between the radio frequency identification reader and the radio frequency identification electronic tag, so as to achieve the purpose of identifying the target. At present, the vehicle identification that supports passive radio frequency identification technology mainly uses the 920-925MHz frequency band. Compared with the radio frequency identification of the 13.56MHz frequency band, the radio frequency identification distance is longer, which is especially suitable for vehicle identification on the road. However, in the application of vehicle management, the available radio frequency identification standards are not limited to one, including the GB / T29768-2013 protocol standar...
