Dual channel-fused emergency video encryption transmission equipment

Abstract

The invention discloses dual channel-fused emergency video encryption transmission equipment. The equipment comprises a 3G / 4G communication module, a 3G / 4G routing control module, first encryption anddecryption equipment, a microwave radio frequency front end, a microwave baseband processing module and a coding, decoding and processing module; the 3G / 4G communication module is used for achieving3G / 4G communication with remote equipment; the 3G / 4G routing control module is used for achieving conversion between 3G / 4G data and IP data; the first encryption and decryption equipment is used for decrypting the IP data sent by the 3G / 4G routing control module and encrypting the output IP data; the microwave radio frequency front end is used for receiving and transmitting a radio frequency signal; the microwave baseband processing module is used for achieving conversion between radio frequency data and the IP data; and the coding, decoding and processing module is used for achieving IP datacommunication with the microwave baseband processing module or the 3G / 4G routing control module and conducting video coding and decoding. The dual channel-fused emergency video encryption transmissionequipment has the high security and the advantages of being low in cost and wide in transmission bandwidth and is applicable to surveillance of cities and surrounding areas, terrorism countering, emergency communication and the like.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-channel fusion emergency video encrypted wireless transmission device. Background technique [0002] In cities, towns and their surrounding areas, when natural disasters, large-scale group activities or violent terrorist incidents occur, the 3G / 4G mobile communication network that relies on basic communication facilities is likely to face paralysis. However, when the above-mentioned incident occurs, the relevant personnel often need to pass on the scene situation of the incident area to the rear personnel, so that the rear personnel can correctly handle or make decisions. At this time, how to transmit high-bandwidth data such as audio and video in the target area to the rear in real time is a key issue. [0003] Satellite communication equipment has the advantages of not relying on public infrastructure and long transmission distance, but the disadvantages ...

AI Technical Summary

Problems solved by technology

[0003] Satellite communication equipment has the advantages of not relying on public infrastructure and long transmission distance, but the disadvantages are high cost of use and low transmission bandwidth; microwave communication equipment has the advantages of high transmission bandwidth and strong adaptability, but the disadvantage is that The transmission distance is limited; the 3G / 4G mobile communication network makes full use of the current infrastructure, which has the advantages of low cost of use and wide coverage, but it depends on the on-site infrastructure and is susceptible to base station working conditions, the number of working sector terminals, and signal interference Devices and other influences
