Abstract

The invention discloses a data transmission method of a reader-writer, a data receiver and a storage medium. The method comprises the steps that a receiving end receives a data packet from a sending end, wherein the data packet comprises a first specific time sequence; the receiving end judges whether a previous data packet of the data packets is received or not according to the first specific time sequence; if the last data packet is not received, the receiving end stores the first specific time sequence into a supplementary transmission buffer area; the supplementary transmission buffer area is scanned regularly, when it is determined that the supplementary transmission buffer area contains the specific time sequence with the storage duration larger than or equal to the timeout duration, a supplementary transmission command is sent to the sending end, wherein the supplementary transmission command contains the specific time sequence with the storage duration larger than or equal to the timeout duration. By adopting the mode, the receiving end does not need to send a receiving confirmation message once when the sending end sends a data packet, so the data interaction can be greatly reduced, the bandwidth can be saved, and the jamming is not easy to occur under the condition of large data volume. Meanwhile, retransmission of packet loss data can be realized.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a data transmission method of a reader-writer, a data receiver and a storage medium. Background technique [0002] Radio Frequency Identification (RFID) is an automatic identification technology and a key technology for building the Internet of Things. The RFID system is mainly composed of readers and transponders. The transponder is mainly composed of antenna, coupling element and chip. Generally speaking, a tag is used as a transponder. Each tag has a unique electronic product code and is attached to the object to identify the target object. The reader, or reader, is mainly composed of an antenna, a coupling element and a chip. It is a device for reading and / or writing tag information, and can be designed as a mobile handheld device or a fixed device. [0003] With the development of ultra high frequency (UHF) technology becoming more and more mature, t...
