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 terms of network topology, the site is directly connected to the WIFI hotspot of the smart screen to access the smart screen network for screen projection. The method to ensure the priority transmission of wireless screen projection data is to allocate more bandwidth occupation time for the wireless screen projection site. It is necessary to first identify whether the site is a wireless screen projection site, and then allocate an appropriate bandwidth occupation time for the site.

[0036] In this embodiment, a method for preferential transmission of smart screen wireless projection data is specifically optimized on the basis of the general Airtime Fairness technology. By configuring the default message characteristics of the smart screen network system, the data is automatically transmitted according to the configured message characteristics. Identify wireless screen projection sites, and allocate bandwidth occupancy time for wireless screen projection sites in a t...

Embodiment 2

[0045] figure 2 It is a frame diagram of a priority transmission system for wireless projection data of a smart screen in this embodiment. As shown in the figure, the priority transmission system of the smart screen wireless projection data includes:

[0046] The message feature configuration module is used to configure the screen projection data message features of the smart screen network system;

[0047] The wireless screen projection site identification module is used to identify the wireless screen projection site according to the configured screen projection data message characteristics during the process of sending and receiving data packets by the wireless network card;

[0048] The airtime scheme configuration module is used to configure the broadband occupation time allocation scheme to the smart network system through the configuration interface;

[0049]The broadband occupancy time allocation module is used to allocate the broadband occupancy time for the wirele...

Abstract

The invention discloses a preferential transmission method for wireless screen projection data of a smart screen. The preferential transmission method comprises the following steps: configuring a screen projection data message characteristic of a smart screen network system; identifying a wireless screen projection site according to the configured screen projection data message characteristic in the process of receiving and transmitting the data packet by a wireless network card; formulating and configuring a broadband occupancy duration allocation scheme, and allocating broadband occupancy duration to the wireless screen projection site according to the broadband occupancy duration allocation scheme; and transmitting the wireless screen projection data according to the distributed broadband occupation duration. According to the invention, preferential transmission of wireless screen projection data of the smart screen can be realized, the broadband occupation time can be flexibly adjusted, the data transmission efficiency is maximized, multi-distribution is supported, and screen projection is not blocked.

Description

technical field [0001] The invention relates to the technical field of wireless data transmission, in particular to a method and system for preferential transmission of wireless projection data of a smart screen. Background technique [0002] At present, the application of smart screen wireless projection is very common, and the demand for four-split screen projection is increasing, 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 for each site Occupancy time, it is impossible to give priority to ensuring that the wireless projection site obtains more broadband occupation time to achieve priority forwarding of screen projection data. The second is that some smart screen APs do not support the Airtime Fairness function, resulting in sites with low-speed connections occupying too long bandwidth and affecting data transmission at key business sites.
