Digital teaching all-in-one machine

Abstract

A digital teaching all-in-one machine comprises a host housing, a wire sorting box, a display bench, a silicon controlled electronic switch, a power supply module, a computer module, a video processing unit circuit, a network management unit circuit, an internet-of-things coordination unit circuit, a current detection unit circuit and an audio decoding unit circuit, wherein all modules and unit circuits are respectively integrated on three branched circuit boards which are installed in the host housing, and the boards are connected through plugging connectors. The display bench facilitates storage of external connection devices. The housing made of ABS engineering plastics prevents electric leakage, the silicon controlled electronic switch prevents contact failure, and video signals of two formats can be output. The digital teaching all-in-one machine has network remote management function, internet-of-things function, voice reminding function and security function and ensures promising prospect.

Description

Technical field [0001] The invention relates to a teaching machine, in particular to a booth equipped with a convenient storage for external equipment of a computer module. The shell is made of ABS engineering plastic, which can prevent electric shock accidents caused by the shell conduction during use. All unit circuits are classified and integrated according to their functions. Three circuit boards, the three circuit boards are connected by plug-in connectors, which reduces the probability of incorrect or fewer wires during production and assembly, and the maintenance is more convenient. SCR electronic switches are used. As the power switch of the power module, it will not cause poor contact due to mechanical contact, and has a long service life. It has the function of outputting HDMI and VGA video signals at the same time. It has the function of network remote management, Internet of things, voice prompts and security functions. Digital teaching all-in-one machine. Backgroun...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the current leakage of the circuit board in the existing teaching machine, it is easy to cause electric shock accidents when the personnel touch the shell. There is no special storage device for the external equipment of the computer module, and the power switch of the control power module is easy to cause contact contact after a long time of use. Bad, the unit circuits in the machine are not integrated according to the function, there are many flying wires between the unit circuits, the wiring is out of order, and there are many points that are prone to failure. It does not support simultaneous output of HDMI and VGA video signals, and does not support network remote management. , does not support the function of the Internet of Things, does not support the function of voice prompts, and does not support the disadvantages of the security function. Electric shock accidents are caused by the conduction of the shell. All unit circuits are classified and integrated on three circuit boards according to their functions. The probability of installing wires is more convenient, and the maintenance is more convenient. The thyristor electronic switch is used as the power switch of the power module, which will not cause poor contact due to mechanical contact, and has a long service life. It has the simultaneous output function of HDMI and VGA video signals. Digital teaching all-in-one machine with network remote management function, Internet of Things function, voice prompt function and security function
