Abstract

The embodiment of the invention discloses a label data extension method and device. The method comprises the steps of obtaining first to-be-encoded data and second to-be-encoded data; wherein the first to-be-coded data is original data corresponding to the label data, and the second to-be-coded data is to-be-expanded data corresponding to the label data; respectively generating first coded data and second coded data according to the first to-be-coded data and the second to-be-coded data, and sending label data to the reader; wherein the label data comprises first data and second data which arearranged alternately, the first data comprises at least two pieces of first coded data, and the second data comprises second coded data. The problem that due to the fact that the capacity of an original reader is limited, the expanded label data cannot be read is solved, the information of the original data contained in the new label data is read on the basis that the information of the originallabel data is read, and the information contained in the original label data is not interfered by newly added information.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data encoding, and in particular, to a method and device for extending label data. Background technique [0002] The electronic tag is the carrier of the radio frequency identification technology. The contactless coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reader. In the coupling channel, energy transmission and data exchange are realized according to the timing relationship. [0003] After the tag is powered on, the signal is transmitted periodically according to the preset rules. When the tag enters the active area of ​​the reader, the tag returns the information to the reader based on the information received by the antenna and sends it to the reader. The reader demodulates and decodes the received information to obtain the information emitted by the tag, which completes the identification process of the ta...
