Abstract

The invention provides a data transmission method and related equipment. The data transmission method comprises the following steps: establishing near-field communication connection with a terminal; in the process of receiving the data sent by the terminal, monitoring the time difference experienced when the near field communication connection with the terminal is disconnected and when the near field communication connection with the terminal is reconnected; and if the time difference is greater than a breakpoint resume time threshold, sending a data retransmission instruction to the terminal.According to the data transmission method provided by the embodiment of the invention, under the condition that the disconnection time difference exceeds the breakpoint resume interval time, a retransmission instruction is sent to the terminal, so that the terminal retransmits the data from the first transmitted data packet after receiving the retransmission instruction, thereby preventing the loss of the data packet transmitted before disconnection in the electronic tag, ensuring the integrity and accuracy of the transmitted data, and avoiding a messy code phenomenon.

Description

technical field [0001] The invention relates to the technical field of electronic tags, in particular to a data transmission method and related equipment. Background technique [0002] If the terminal such as mobile phone or Reader (reader-writer) is separated from the electronic tag during the data transmission process, and exceeds the time limit for resuming transmission, then when the terminal is close to the electronic tag again, although data transmission can still be performed, the electronic The content displayed on the label will be garbled. And the longer the data transfer time before disconnection, the larger the area that is not displayed on the display. [0003] It can be seen that when the time limit for resuming transmission is exceeded, when the terminal is close to the electronic tag again, it does not resend from the first data packet sent, resulting in the loss of the data packet transmitted before the disconnection in the electronic tag. This leads to ga...
