Problems solved by technology
Some current solutions adopt line-of-sight data link, image transmission radio + digital transmission radio, etc. Although they can solve high-definition video transmission under line-of-sight conditions, their anti-occlusion ability is poor
Although public wireless network implementations based on 3G multi-link aggregation and single 4G terminals (including but not limited to TDD LTE and FDD LTE) are suitable for complex environments, in the real-time transmission process, the wireless bandwidth is small, and the transmitted high-definition images cannot achieve the desired effect. , there is an urgent need for a more efficient high-definition video transmission device based on public digital mobile communications

The invention discloses a data sending method and system. The method comprises: video data and telemetering data are received; the video data and the telemetering data are processed into one path of data in multiplexing and then the one path of multiplexing data are divided into N paths of data; and then the N paths of data are sent to a ground control center by K mobile communication data channels. Therefore, because the divided data are sent to the ground control center by the K mobile communication data channels, an effect of real-time high-definition data transmission by using a plurality of narrow-bandwidth mobile communication data channels is realized and a high-speed channel capable of meeting requirements of unidirectional digital video transmission and bidirectional real-time telemetering and remote control transmission is formed, thereby improving the real-time cross-region high-definition video transmission capability of an unmanned aerial vehicle.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a data sending method and system. Background technique [0002] At present, the application of drones in military and civilian fields is becoming more and more extensive. The UAV video communication transmission system generally saves the collected on-site video signals in the onboard hard disk during the flight of the mission aircraft, and transmits the data to the ground control center in real time through the wireless communication network. Due to the large amount of high-definition video data, the bandwidth requirements are relatively high during real-time transmission. Some current solutions adopt line-of-sight data link, image transmission radio + data transmission radio, etc. Although they can solve high-definition video transmission under line-of-sight conditions, their anti-occlusion ability is poor. Although public wireless network implementatio...
