Smart screen data processing method based on Socket message

Abstract

The embodiment of the invention relates to a smart screen data processing method based on a Socket message. A smart screen comprises an application layer module, a server side module and a client side module. The method comprises the following steps: a server side module receives a Socket message from an application layer module to generate a first application layer message and performs application layer control instruction identification on the first application layer message; the method also includes: if the first application layer message is identified as an application layer control instruction, executing a corresponding application layer instruction processing flow; receiving the Socket message from the client module to generate a first client message, and performing client control instruction identification on the first client message; and if the first client message is identified as the client control instruction, executing a corresponding client instruction processing flow. According to the invention, the problem of serious lag between the handwriting and the screen display data can be solved, the situation of handwriting data loss can be avoided, the data transmission efficiency is improved, and the real-time synchronization effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing method for a smart screen based on Socket messages. Background technique [0002] A smart screen is an electronic screen with an operating system and storage space. When the smart screen is used for online teaching, the smart screen, electronic pen and remote server will form a device interconnection network, and the data interaction process between the smart screen and the electronic pen will be processed through the remote server. However, in practical applications, we will find that the data interaction process participated by the remote server is affected by network conditions. There is often a serious lag between the handwriting data of the electronic pen and the screen display data of the smart screen. In extreme cases, even Handwriting data may be lost and cannot be displayed on the screen. Contents of the invention [0003] The purpose of the...

AI Technical Summary

Problems solved by technology

In this way, the traditional smart screen-electronic pen data interaction process participated by the remote server is completely dominated by the local smart screen, which can solve the problem of serious lag between handwriting data and screen display data caused by network reasons. It can also avoid the loss of handwriting data; in addition, directly adopting the Socket message mechanism for data transmission can also solve the problems of excessive redundant data and low efficiency of effective data transmission caused by the use of upper-layer network protocols, and improve data transmission efficiency. Efficiency, enhancement of handwriting, and the effect of real-time synchronization of screen display data
