Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the default Airtime Fairness function cannot guarantee that the wireless projection site can obtain more bandwidth occupation time to achieve priority forwarding of projection data, resulting in the problem that sites with low speed connections occupy too long broadband time
The purpose is to provide a method and system for preferential transmission of wireless projection data of smart screens, so as to solve the problem of priority transmission of wireless projection data

Embodiment 1

[0035] In the network topology, the site directly connects to the WIFI hotspot of the smart screen to access the smart screen network for screen projection. The way to ensure the priority transmission of wireless screen-projecting data is to allocate more bandwidth occupation time to wireless-screen-projecting sites. This requires identifying whether the site is a wirelessly mirrored site before assigning the appropriate bandwidth footprint to the site.

[0036] The present embodiment is a smart screen wireless screen projection data priority transmission method, based on the general Airtime Fairness technology for specific optimization, through the smart screen network system default message characteristics configuration, according to the configured message characteristics automatically identify the wireless screen projection site, targeted for the wireless screen projection site to allocate broadband occupation time, thereby overcoming the general Airtime Fairness technology to ...

Embodiment 2

[0045] Figure 2 For the present embodiment, a smart screen wireless projection data priority transmission system framework diagram. As shown in the figure, the priority transmission system for wireless screen projection data of the smart screen, including:

[0046] Message characteristic configuration module for configuring the screen projection data message characteristics of the smart screen network system;

[0047] Wireless screen-projection site identification module, which is used to identify wireless screen-projection sites according to the configured screen-projection data message characteristics in the process of sending and receiving packets from wireless network cards;

[0048] Airtime scheme configuration module, which is used to configure the broadband occupancy time allocation scheme to the smart network system through the configuration interface;

[0049] Broadband occupancy time allocation module, which is used to allocate broadband occupancy time to wireless scree...

Abstract

The invention discloses a method for preferential transmission of wireless screen projection data of a smart screen, comprising the following steps: configuring the characteristics of the screen projection data message of the smart screen network system; Message characteristics, identify wireless projection sites; formulate and configure broadband occupation time allocation scheme, allocate broadband occupation time for wireless projection sites according to broadband occupation time allocation scheme; transmit wireless projection data according to allocated broadband occupation time. The invention can realize the priority transmission of wireless screen projection data of the smart screen, and can flexibly adjust the bandwidth occupation time, so as to maximize the data transmission efficiency, and at the same time support multi-distribution while screen projection is not stuck.

Description

Technical field [0001] The present invention relates to the field of wireless data transmission technology, specifically to a smart screen wireless screen projection data priority transmission method and system. Background [0002] At present, the application of wireless screen projection of smart screen is very common, and the demand for four-screen screen projection has increased, but the AP (WIFI hotspot) of the smart screen has the following defects: First, the default Airtime Fairness function provides the same amount of broadband occupation time for each site, and it is impossible to prioritize the wireless screen projection site to obtain more broadband occupation time to achieve priority forwarding of screen projection data. Second, the AP of some smart screens does not support the Airtime Fairness function, resulting in sites with low speed connections occupying too long broadband occupation time, affecting the data transmission of key business sites.
