A general wireless transmission device based on nb-iot

Abstract

The invention discloses a general wireless transmission device based on NB-IOT, which includes a main body shell and a central processing system, an active slot is opened on the top side of the back of the main shell, and a storage slot is opened on the back of the main shell and located at the bottom of the active slot , the inside of the movable groove is rotatably connected with movable balls, and the present invention relates to the technical field of wireless transmission equipment. The NB-IOT-based universal wireless transmission device can store the high-gain antenna in the storage slot when the walkie-talkie is not in use, and then protect the antenna through a protective case to prevent accidental damage to the antenna The problem, to a certain extent, also increases the service life of the antenna. At the same time, the walkie-talkie uses NB-IOT technology for voice and image transmission, and the voice can be encrypted. Conventional wireless transmission equipment cannot receive encrypted voice data. The privacy of voice transmission is guaranteed, and the practicability of the wireless transmission device is also improved.

Description

Technical field [0001] The present invention relates to the technical field of wireless transmission equipment, in particular a universal wireless transmission device based on NB-IOT. Background technique [0002] Wireless transmission refers to a way of using wireless technology for data transmission. Wireless transmission and wired transmission are corresponding. With the growing development of wireless technology, wireless transmission technology is increasingly accepted by all walks of life, wireless image transmission as A special way is also gradually optimistic by the majority of users. It has strong installation, strong flexibility, and cost-effective characteristics make the monitoring system of more industries use wireless transmission mode, establish the connection between the monitoring point and the monitoring center, wireless monitoring technology has been In modern transportation, transportation, water, shipping, railways, public security, fire, border inspection s...

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
