Abstract

In order to eliminate bottlenecks and enable the read data format of the prior mainstream RFID to be compatible, the invention designs a compatible data format used for active RFID. The data format adopts hexadecimal digital representation, and the content of the data format comprises a format version number, an RFID manufacturer code, an RFID model code, an RFID memory card category code, a supported battery type code, an RFID command block, an RFID command return value, an RFID data block, a standby data block and an RFID terminator, wherein the RFID command block comprises an RFID command start symbol, an RFID bit rate, an RFID command code, the number of RFID command parameters, RFID command parameters, an RFID command parameter check code and an RFID command terminator; the RFID data block comprises an RFID data start symbol, the number of RFID data, RFID data values, an RFID data check code and an RFID data terminator; and the standby data block is reserved for standby application.

Description

technical field [0001] [001] The present invention relates to a data format of RFID used in logistics, and more particularly, to a compatible data format used in active RFID. Background technique [0002] [002] RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification. Often called inductive electronic chips or proximity cards, proximity cards, contactless cards, electronic tags, electronic barcodes, and so on. RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple electronic tags at the same time, and the operation is fast and convenient. [0003] [003] In enterprise distribution and retail distribution, RFID h...
