Universal wireless transmission device based on NB-IOT

Abstract

The invention discloses a universal wireless transmission device based on NB-IOT (Narrow Band Internet of Things). The device comprises a main body shell and a central processing system, wherein a movable groove is formed in one side of the top of the back face of the main body shell; a storage groove is formed in the back face of the main body shell and located in the bottom of the movable groove; and a movable ball is rotatably connected into the movable groove. The universal wireless transmission device based on NB-IOT comprises a base station and a base station, when the interphone is notused, the interphone can be used; the high-gain antenna is accommodated in the accommodating groove; the antenna is protected through the protection of the protection shell; the problem of unintentional damage to the antenna is prevented; the service life of the antenna is prolonged to a certain extent; meanwhile, the interphone adopts the NB-IOT technology to carry out voice and image transmission, voice can be encrypted, and conventional wireless transmission equipment cannot receive encrypted voice data, so that the privacy of voice transmission is ensured, and the practicability of the wireless transmission equipment is also improved.

Description

technical field [0001] The invention relates to the technical field of wireless transmission equipment, in particular to a general wireless transmission equipment based on NB-IOT. Background technique [0002] Wireless transmission refers to a way of data transmission using wireless technology. Wireless transmission and wired transmission are corresponding. With the development of wireless technology, the application of wireless transmission technology is more and more accepted by all walks of life. Wireless image transmission as A special way of use is also gradually favored by the majority of users. Its characteristics of easy installation, strong flexibility, and high cost performance make monitoring systems in more industries adopt wireless transmission methods to establish connections between monitored points and monitoring centers. Wireless monitoring technology has already It has been widely used in modern transportation, transportation, water conservancy, shipping, r...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a general-purpose wireless transmission device based on NB-IOT, which solves the problem that the antenna of the walkie-talkie is mostly fixed with an external leakage type, and cannot be stored when not in use, and cannot be installed by shrinking alone. If there is enough protection effect, it is easy to damage it and affect the subsequent normal use. At the same time, when it is necessary to transmit confidential voice data, the existing walkie-talkie is easy to cause the leakage of voice information
