Problems solved by technology

[0002] At present, the common method of synchronous display of screens applied to classroom software is to use the entire screen to refresh the screen capture transmission display at regular intervals. Regardless of whether the screen has changed or not, the entire screen picture is transmitted, and the method of synchronous display of the entire screen consumes a lot of wireless network traffic. Moreover, there is often a freeze phenomenon, and the screen display is not smooth; the higher the defined refresh rate, the more traffic is consumed and the more freezes, and it takes up a lot of system memory and CPU usage of the mobile terminal device, resulting in slow software switching and affecting software operating efficiency.

Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, this example provides a classroom synchronization system based on a wireless network, including: a wireless router, an all-in-one computer, a mobile terminal and a server, the mobile terminal is connected to the server through a wireless router, and the server is The router is connected to the all-in-one computer; the mobile terminal includes a screen synchronization processor for listening to and synchronizing the picture of the brush drawing board; the classroom synchronization system includes the following steps:

[0039]Listening step, when the paintbrush panel of the mobile terminal is activated, the screen synchronization processor listens to the picture information of the paintbrush panel in real time, and sends the picture synchronization command to the server side to request synchronous display, after the synchronous display request is authorized , the mobile terminal compresses the picture of the first paintbrush panel...

Embodiment 2

[0048] On the basis of Embodiment 1, the mobile terminal described in this example includes a teacher machine and a student machine, and the teacher machine is used to realize wireless mouse, PPT control, send task notes, paintbrush, write, control student machine and homework assignment screen projection, and the student machine is used to implement tasks, paint brushes, write, hand in picture assignments and hand in video assignments.

[0049] Such as image 3 and Figure 4 As shown, after the authorized user logs in, the teacher machine described in this example implements the following operations through the listening and processing of events on the server side: the operation of the left mouse button, right button and double-click of the left button; Page back, play previous page and play next page operations; send task note to the selected student computer; synchronously display the brush and drawing board of the teacher computer on the screen of the all-in-one computer;...

Abstract

The invention provides a class synchronization system based on the wireless network. The class synchronization system based on the wireless network comprises a wireless router, an all-in-one computer, a mobile terminal and a server side. The method adopted in the class synchronization system comprises the monitoring step, the judging step and the outputting step. In the monitoring step, the picture information of a brush panel of the mobile terminal is monitored in real time, and a picture synchronization order is sent to the server side to request for the synchronous displaying. In the judging step, whether the picture of the brush panel changes or not is judged, wherein if yes, a screen synchronization processor packages the coordinate pixel points and the corresponding color values of the changing parts in real time and transmits the coordinate pixel points and the corresponding color values of the changing parts to the server side to be processed, and synchronization picture information is generated. In the outputting step, the synchronization picture information is output to the all-in-one computer to be displayed. The screen picture of the mobile terminal can be synchronized to the all-in-one computer to be displayed in real time, the consumption on the CPU, the internal storage and the wireless network flow is reduced, the speed and running efficiency are high, and the synchronization picture is fluent.
