Embodiment Construction

[0036] The long-distance large data volume wireless communication method for unmanned aerial vehicle described in the present invention, comprises the following steps:

[0037] S1. Superimpose the video images taken by the UAV and the performance parameters during the flight of the UAV to form video data;

[0038] S2, the video data that step S1 obtains is carried out compression coding; Described compression coding comprises the following steps:

[0039] S21, the video data is subjected to hierarchical processing; the video data is divided into a video coding layer (VCL) and a network abstraction layer (NAL), wherein the video coding layer is used to compress the content of the video data; the network abstraction layer is used for programming Data format, in order to realize the transmission of video data in different networks;

[0040] S22. Perform intra-frame predictive encoding on the video data; divide the same video image into several macroblocks, and then perform encod...

Abstract

The invention discloses a long-distance large-data-volume wireless communication method for unmanned aerial vehicles, which can not only realize digital transmission of wireless video data, but also counteract interference problems in wireless channels so as to improve the transmission reliability of the wireless transmission system. This method forms video data by superimposing the video images taken by the UAV and the performance parameters during the flight of the UAV; then compresses and encodes the video data, and finally transmits the encoded video data to the client, and the prediction-based HARQ algorithm is used for error control in wireless transmission, which can not only realize the digital transmission of wireless video data, but also use the prediction-based HARQ algorithm to control the error of the wireless transmission channel Control, can counteract the interference problem in the wireless channel so as to improve the transmission reliability of the wireless transmission system. It is suitable for popularization and application in the field of wireless transmission technology.

Description

technical field [0001] The invention relates to the technical field of wireless transmission, in particular to a long-distance large-data volume wireless communication method for unmanned aerial vehicles. Background technique [0002] In order to realize long-distance UAV operation and on-site fault judgment, it is necessary to ensure that the ground base station receives clear and stable image data, and the amount of image transmission data is very large, so it is necessary to conduct research on long-distance large-data wireless communication platforms. The main problems to be solved here are: data transmission rate, anti-interference of data information, information compression and communication distance. For the study of long-distance wireless communication, a lot of research has been done at home and abroad in recent years, and many achievements have been made. Due to the special application occasions of drone inspection transmission lines, many iron towers are located...
