Embodiment Construction

[0057] It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0058] Reference figure 1 , figure 1 It is a structural block diagram of the first embodiment of the UAV communication switching system based on Beidou short message of the present invention.

[0059] Such as figure 1 As shown, the UAV communication switching system based on Beidou short message may include: a position acquisition module 1001, a message sending module 1002, a distance calculation module 1003, and a communication switching module 1004. Among them, the location acquisition module 1001 is used to communicate with a radio station to acquire real-time location information of the drone, and set a preset communication switching distance; the message sending module 1002 is used to generate Beidou short based on the real-time location information Message, the Beidou short message is transmitted to the ground co...

Abstract

The invention discloses an unmanned aerial vehicle communication switching method and system based on Beidou short messages, and the method comprises the following steps: employing a radio station forcommunication, obtaining the real-time position information of an unmanned aerial vehicle, and setting a preset communication switching distance; generating a Beidou short message according to the real-time position information, and transmitting the Beidou short message to a ground communication terminal through a Beidou satellite; calculating a first distance from the unmanned aerial vehicle tothe ground communication terminal according to the real-time position information; when the first distance is greater than the preset communication switching distance, switching to the Beidou short message communication technology for communication; setting different communication modes according to the relationship between the first distance and the preset communication switching distance, so that the reliability of data transmission in the remote communication process of the unmanned aerial vehicle is ensured, the phenomenon of data loss is avoided, the success rate of data transmission is improved, and the communication quality is ensured.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a UAV communication switching method and system based on Beidou short messages. Background technique [0002] At present, most of the technical applications of Beidou short message communication technology in animal husbandry are the use of Beidou positioning technology to realize the real-time position display of the herd, the historical trajectory query, or the combination of drones to realize further grazing management. However, traditional drones cannot adapt to the signal environment of Inner Mongolia, Xinjiang, Tibet, Qinghai and other regions, cannot guarantee the reliability of long-distance data transmission under the condition of incomplete coverage of mobile base stations, and cannot realize real-time control during the grazing process. Due to the comprehensive influence of various environmental factors, the success rate of long-distance data transmission is not high...
