Abstract

The application discloses a data transmission method of a reader-writer, a data receiver and a storage medium. The method includes: the receiving end receives a data packet from the sending end, wherein the data packet contains a first specific timing; the receiving end judges whether the previous data packet of the data packet is received according to the first specific timing; if the previous data packet is not received , then the receiving end will store the first specific time sequence in the retransmission buffer; scan the retransmission buffer regularly, and when it is determined that the retransmission buffer contains a specific time sequence whose storage duration is greater than or equal to the timeout duration, send Send a retransmission command, and the retransmission command includes a specific sequence whose storage duration is greater than or equal to the timeout duration. Using this method does not require the sender to send a confirmation message every time a data packet is sent, which can greatly reduce data interaction, save bandwidth, and is not prone to lag when the amount of data is large. At the same time, the retransmission of lost packet data can also 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...
