Video conference telephone system

Abstract

The invention discloses a video conference telephone system, which comprises an audio module, a video module, an audio and video processing module, a wireless communication module, a microprocessor, adisplay and a power supply module, wherein both the audio module and the video module are connected with the audio and video processing module, and the microprocessor is connected with the audio module, the video module, the display and the power supply module; the power supply module includes a voltage input end, a transformer, a bridge rectifier, a first capacitor, a first triode, a second resistor, a third capacitor, a second triode, a first diode, a first potentiometer, a second capacitor and a voltage output end, one end of a primary coil of the transformer is connected with one end of the voltage input end, the other end of a secondary coil of the transformer is connected with the other end of the voltage input end, and one end of the secondary coil of the transformer is connected with an input end of the bridge rectifier. The video conference telephone system is simple in circuit structure, low in cost, convenient to maintain and high in circuit safety and reliability.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a video conference telephone system. Background technique [0002] Video conferencing system, also known as video conference system, refers to two or more individuals or groups in different places, through transmission lines and multimedia equipment, to exchange sound, video and documents to achieve instant and interactive communication. To realize the system equipment of teleconferencing. The use of video conferencing is a bit like a phone call. In addition to seeing the person you are talking with and communicating in words, you can also see their expressions and actions, so that people in different places can communicate as if they are in the same conference room. The power supply part of the traditional video conferencing system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain. In addition, because th...
