Communication mode switching system

Abstract

The invention belongs to the technical field of wireless communication, and particularly relates to a communication mode switching system which comprises a projector, a projection lamp, wire passing grooves, supporting rods, a heat dissipation shell, a thermal inductor, a fan, a first lifting rod, a fixed shell, a handle, a movable block, an ultraviolet sensor, a clamping groove, a sliding grooveand a remote controller. One side of the outer wall of each projector is provided with a cooling fin. The projection lamp is arranged on the outer wall of the projector, a first protection shell is arranged on the outer side of the projection lamp, a first rotating bolt is arranged above the first protection shell, the wire passing groove is formed in the other side of the outer wall of the projector, a second protection shell is arranged on the outer side of the wire passing groove, and a second rotating bolt is arranged above the second protection shell. And a protective cover is arranged above the second rotating bolt. According to the communication mode switching system, by arranging the cooling fins, a heat dissipation effect can be achieved when the projector works, internal parts ofthe projector can be damaged, and therefore the using effect of the device is greatly improved.

Description

technical field [0001] The present invention relates to the technical field related to wireless communication, in particular to a communication mode switching system. Background technique [0002] Wireless communication refers to long-distance transmission and communication between multiple nodes without transmission through conductors or cables. Wireless communication can be performed using radios, radios, etc. Wireless communication includes various fixed, mobile and portable applications, such as two-way radio , mobile phones, personal digital assistants, and wireless networks. Examples of other radio wireless communications include GPS, garage door remote controls, and wireless mice. Most wireless communication technologies use radio, including Wi-fi, which is only a few meters away. It also includes the deep space network that communicates with Voyager 1 and has a distance of more than millions of kilometers. However, some wireless communication technologies do not use ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a communication mode switching system, which solves the problem that the currently used communication mode switching system does not have the effect of heat dissipation. When the internal temperature of the device is too high, it may damage the internal parts. cause damage, and does not have the function of protection. The device is easily damaged by external factors, and does not have the function of lifting. During use, it is not convenient to adjust its height according to external adjustments, and it does not have convenient The effect of disassembly, when not in use, it is not convenient to disassemble the device from the cooling system, thus greatly reducing the use effect of the device
