Ground-air cooperative networking system and control method

Abstract

The invention relates to a ground-air cooperative networking system and a control method, the system comprises a high-altitude mobile gateway node device, a ground mobile gateway node device and a supervision background, and the high-altitude mobile gateway node device is responsible for collecting images from high altitude and sending the images to the supervision background in real time; the ground mobile gateway node device is responsible for collecting images from the ground and sending the images to the supervision background in real time; and the supervision background controls the two gateway node devices. According to the networking system, target detection, image acquisition and video transmission are carried out from high altitude by taking the unmanned aerial vehicle as a main part, and image acquisition and auxiliary survey are carried out on plane terrain by adding the trolley on the ground, so that clear high-altitude and plane image information, position information and terrain information can be obtained at the same time. According to the invention, the multi-rotor unmanned aerial vehicle and the unmanned trolley are utilized to effectively complement the shortages of the multi-rotor unmanned aerial vehicle and the unmanned trolley during operation, so that the inspection task is more efficiently completed, and the loss is greatly reduced during operation failure.

Description

technical field [0001] The present invention belongs to the field of communication network systems, and specifically relates to a ground-air collaborative networking system, specifically a drone-based target detection, image acquisition and video transmission from high altitude, and a trolley on the ground. A networking system for auxiliary survey of plane terrain and a control method for the system. Background technique [0002] At the beginning of the 1920s, radio-controlled small aircraft appeared on the battlefield of World War I. After it was successfully developed and put into the battlefield, the battlefield changed the situation in an instant. Since then, countries have vigorously carried out the research and development of drones. , whether it is in the military field where it was first applied, or the agricultural field until now, or other fields. UAVs play an indispensable role. From the appearance of UAVs to the present, various forms have been derived and vario...

However, the trolley also has obvious defects, that is, the collection information plane is single, and image information can only be obtained from a plane angle

[0004] ZL201310065386X discloses an air-space-ground collaborative multimedia network system, which includes a plurality of communication nodes, each communication node is composed of space-based communication network equipment, land-based communication network equipment or space-based communication network equipment, within a radius of no more than 100 In the near-field area of ​​1000 km, microwave communication is used between communication nodes, and satellite communication is used between communication nodes in the near-field area and communication nodes in the remote area. The data stream communicates with IP as the information bearing method. The system realizes air-space-ground integrated wireless communication and needs to realize communication through satellites, but does not involve the system framework based on 802.11 standard local area network

[0005] ZL2018110576788 discloses a multi-UAV cooperative control system. Multiple UAVs in the system are connected through an inter-machine communication network. The function of this system can only be played by the machine, and it does not involve the ground mobile gateway communication node system

[0006] ZL2019109917926 discloses an air-ground collaborative unmanned system, which uses multiple unmanned aerial vehicle networks composed of unmanned aerial vehicles and a robot network composed of multiple robots for human-computer interaction, receiving detection information and displaying detection information in real time , to transmit and control the air unmanned system and the ground unmanned system, but the implementation of this system requires too many high-altitude mobile gateway nodes, which increases the probability of aircraft failure, and the unmanned system does not disclose the specific autonomous planning system

[0007] It can be seen that when the above-mentioned stand-alone operation fails, the collected data is difficult to return, and the possibility of damage to the equipment carried by the aircraft is greatly increased. In addition, the car also has obvious defects, that is, the plane of the collected information is single, and it can only be viewed from a plane perspective. Get image information
