Master network method, slave network method, and data frame structure of data distribution and wireless transmission

Abstract

The invention discloses a master station networking method, a slave station networking method, and a data frame structure for data distribution and wireless transmission, wherein the data transmission of the master station and the slave station after network access follows the data frame structure; the data frame structure includes T combined subframes of slave stations, subframes of the master station, and dynamically assignable subframes; the combined subframes of the slave stations include subframes of the master station and subframes of the slave stations; the subframes of the master station include N distributable frames; The slave station subframe includes M allocatable frames; the master station subframe includes P allocatable frames, and the master station subframe is used for the master station to transmit data; the dynamically assignable subframe includes Q allocatable frames, and the master station subframe includes Q allocatable frames. A station or an authorized slave station transmits data by occupying the dynamically allocable subframe; the allocatable frame includes X time slots. The data frame of the present invention has sub-frames that can be allocated dynamically, which satisfies the requirements of changing data sources of nodes in the system to a certain extent. The network entry of late-entry stations does not affect the network entry status of already-entry stations, and the present invention has a short networking time.

Description

technical field [0001] The present invention relates to the technical field of data wireless transmission, and more specifically, relates to a master station networking method, a slave station networking method, and a data frame structure for data distribution wireless transmission. Background technique [0002] The radio station is a transceiver device for radio transmission, usually in half-duplex mode, that is, it is generally in the receiving mode and does not transmit radio frequency signals. When the signal needs to be transmitted, the radio station is controlled to enter the transmission mode to transmit radio frequency signals into the air, and the radio station does not receive the signal at the same time when transmitting. [0003] Multiple stations can form a wireless communication network for data transmission ("data transmission" is sometimes referred to as "data transmission"), such as figure 1 shown. The main technical problems to be solved in radio network ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problems in the existing radio networking method that the networking time is relatively long or the re-entry time of the late network radio stations is relatively long, the present invention provides a master station networking method for data distribution and wireless transmission, and a slave station group Networking method, data frame structure, its networking time is short, and the network entry of late network stations does not affect the stations already connected to the network, that is, no need to synchronize again after entering the network
