Embodiment 1

[0022] The intelligent video communication control circuit capable of wireless screen projection in the embodiment of the present invention includes a control module, a WIFI module, a 5G communication module, a wired communication module, an audio processing module, a video communication processing module, an expansion interface module, a display module, an infrared ( Bluetooth) wireless remote control module, projection screen module and anti-interference circuit, the WIFI module, 5G communication module, wired communication module, audio processing module, video communication processing module, expansion interface module and display module are all connected with the main control module The output end is electrically connected;

[0023] The screen projection module is electrically connected to the control module, the anti-interference circuit is also electrically connected to the control module, the screen projection module includes a LAN module, and the screen projection modu...

Embodiment 2

[0033] The present invention also discloses a screen projection device, which includes the intelligent video communication control circuit described in the first embodiment that can realize wireless screen projection. The method of using the screen projection device is: connect the mobile terminal to the screen projection device wirelessly, or connect through a cable, so that the content on the display module of the mobile terminal can be shared with the display unit of the screen projection device, so that the screen projection device can be used as a mobile terminal extended display screen use.

[0034] To sum up: the present invention designs a "retrigger" anti-jamming circuit in the control circuit to prevent the program from deviating from the normal track due to network fluctuations, etc., and sends a reset pulse to the control module when the program runs abnormally. Reset, forcing the program to return to the normal running track to ensure the stability of the projecti...

Abstract

The invention discloses an intelligent video communication control circuit capable of realizing wireless screen projection and a screen projection device, and particularly relates to the field of wireless screen projection. The circuit comprises a control module, a WIFI module, a 5G communication module, a wired communication module, an audio processing module, a video communication processing module, an expansion interface module, a display module, an infrared (Bluetooth) wireless remote control module, a screen projection module and an anti-interference circuit. The WIFI module, the 5G communication module, the wired communication module, the audio processing module, the video communication processing module, the expansion interface module and the display module are electrically connected with the output end of the main control module. According to the invention, the retrigger anti-interference circuit is designed in the control circuit to prevent a program from being separated froma normal track due to network fluctuation and other reasons, and a reset pulse is sent to the control module to reset the program when the program abnormally runs, so that the program is forced to return to the normal running track, and the stability of a projection picture is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless screen projection, and more specifically, the invention relates to an intelligent video communication control circuit and a screen projection device capable of realizing wireless screen projection. Background technique [0002] Today, the average broadband download rate in my country can reach 35.46Mbit / s, a 13.2% increase from Q1. At the same time, the fifth-generation mobile communication technology has also begun to enter commercial use. With the rise of cloud office, high-definition video calling has gradually become a necessary service for enterprises and institutions. At present, the market is basically mobile phone-based video communication APP software. This software uses the camera on the mobile phone to make video calls, which can realize point-to-point and is relatively convenient to use. [0003] However, this kind of APP software has the following disadvantages: the screen size of t...
