Technical field.
Background technology
The real-time video transmission of unmanned plane is the major function of UAV system, and unmanned aerial vehicle platform is by carrying video acquisition
Equipment, real-time image acquisition information come realize its scout monitoring task.Exist when unmanned plane carries out data transmission with ground anti-dry
Disturbing can force difference, the shortcomings of transmission range is short, speed is slow, it is difficult to meet the real time monitoring to specifying region.If unmanned machine operation
Environment is complex, for example executes task of taking photo by plane in mountain area, and the mountain ridge is more, the case where being blocked between earth station and unmanned plane,
Vision signal may interrupt transmission on unmanned plane.This will lead to that image that ground receiver arrives is unstable in addition image it is temporary in
Disconnected situation seriously reduces image transmitting Stability and dependability of the unmanned plane under above-mentioned handling situations.Therefore, invention base
It is very necessary in the UAV Video real-time transmission system of 4G, it is of great significance for unmanned air vehicle technique popularization and application.
Invention content

TD-LTE4G transmission technologys, realize the real-time Transmission system of HD video data stabilization.
The technical scheme is that：Unmanned plane based on 4G communication standards H.264 Video transmission system, including camera lens,
Video acquisition module, two 4G wireless transport modules, the base stations 4G, two video processing modules, video playback apparatus and ground prison
Measured center, wherein camera lens, video acquisition module, a video processing module, a 4G wireless transport module are sequentially connected setting
On unmanned plane；Another 4G wireless transport module, another video processing module and video playback apparatus are sequentially connected setting
At ground monitoring center.Wherein camera lens is high definition camera lens, and the optical signalling of camera lens is become digital signal, nothing by video acquisition module
Digital signal is carried out corresponding compression and code conversion H.264 code stream by the video processing module on man-machine, is wirelessly passed by 4G
Defeated module is sent to the base stations 4G, by the 4G wireless transport modules of video data transmission to ground monitoring center, by ground monitoring
It is played in real time in video playback apparatus or ground monitoring center after the video processing module decompression at center.
Wherein, two 4G wireless transport modules include TD-LTE 4G communication modules and antenna, the TD-LTE 4G
Communication module uses Huawei's ME909S-8221Mini chips.
Wherein, the chip of two video processing modules is Huawei Hi3520D.
The present invention has a kind of unmanned plane based on TD-LTE 4G, and H.264 Video transmission system, advantage and effect are：Depending on
Real-time Transmission and reception of the frequency image data from unmanned plane to ground realize that unmanned plane is real-time under various complicated flight ranges
Stability monitoring function has the characteristics that transmission strong interference immunity, distance is remote, rate is fast, instantaneity is good.
