Embodiment Construction

[0035] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0036] Such as figure 1 as shown, figure 1 It is a flowchart of a radio frequency data transmission method of the present invention. A radio frequency data transmission method, the method specifically includes:

[0037] S101. The electronic tag monitors the transmission enable message sent by the reader;

[0038] S102. When the electronic tag receives the transmission enable message sent by th...

Abstract

The present invention relates to a radio frequency data transmission method and system. The radio frequency data transmission method includes: an electronic tag monitors a transmission enabling message sent by a reader; when the electronic tag receives the transmission enabling message sent by the reader Enable message or when the electronic tag has not received the transmission enable message sent by the reader after the preset sending interval time, the electronic tag sends a transmission request message to the reader; After the reader receives the transmission request message, the electronic tag monitors the channel selection message sent by the reader; the electronic tag enables a wired channel or a wireless channel according to the channel selection message; The electronic tag transmits data to the reader through the enabled wired channel or wireless channel. The present invention can save energy consumption to the greatest extent and ensure the real-time and continuity of data collection.

Description

technical field [0001] The invention relates to the field of the Internet of Things and the field of radio frequency technology, in particular to a radio frequency data transmission method and system. Background technique [0002] Radio frequency identification technology is a technology that uses radio frequency signals to achieve non-contact information transmission through spatial coupling and achieve identification purposes through the transmitted information. It has the advantages of fast reading, easy manipulation and flexible use. Radio frequency identification technology is suitable for building the Internet of Things. As the front end of the Internet of Things, radio frequency identification equipment can realize the function of data collection. [0003] In the process of using radio frequency identification equipment for data transmission, the electronic tag needs to obtain working power before it can start data transmission. In the prior art, in order to carry ou...
