Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

The unmanned aerial vehicle parking apron mainly completes storage, daily management and data processing of unmanned aerial vehicles in the unmanned area. It has various equipment to maintain the health of unmanned aerial vehicle to protect and charge when unmanned aerial vehicle does not carry out the task. In addition, the apron can also replace the equipment that unmanned aerial vehicle carried by machinery, satisfies different work needs. In addition, because the air park is provided with the edge equipment with stronger data processing capability than the embedded processor carried by the unmanned aerial vehicle, the big data can be rapidly processed, and the defect of the computing capability of the airborne terminal is overcome.
The unmanned aerial vehicle often operates in areas without signals, so that it is very necessary to deploy a special communication network to cover a flight area, and ensure flight safety and smooth information reception. Note that GS communications include drone communications, satellite communications, and internet communications. Unmanned aerial vehicle communication includes image transmission and text transmission of radio frequency equipment, and satellite communication equipment includes global navigation satellite system.
As an actuator, drones typically carry different devices to perform tasks, including visible light cameras, communication relays, transmitters. When performing the task, a plurality of ground stations provide corresponding types of unmanned aerial vehicles carrying equipment. Wherein, unmanned aerial vehicle divide into terminal unmanned aerial vehicle and communication unmanned aerial vehicle according to its function.
The terminal unmanned aerial vehicle is used as a high-altitude nacelle and performs various high-altitude tasks by using various types of equipment. However, due to limited device capabilities, tasks are not always successful. Generally, the task success rate is inversely related to the distance between the task target and the drone.
The terminal drone communicates with a single or multiple ground sensors. The terminal unmanned aerial vehicle with different mission targets has different distances from the ground military system. In some cases, no one will enter an area that cannot be covered by the GS signal. For example, drones need to operate on mountains. In this case, the drone cannot maintain smooth communication. Thus, the communicating drone can stay between the terminal drone and the ground sensor, which provides wide coverage to establish a temporary, dedicated relay communication channel. The unmanned aerial vehicle terminal can ensure that the unmanned aerial vehicle terminal can receive and send information in time during working; the channel bandwidth of the communication equipment is 8MHz, the frequency band is 750MHz, the video transmission delay in the test range is 0.47 seconds, and the computing equipment comprises an Intel Xeon E5-2678V 3 processor and a 2080Ti display card.

In conducting the test, Jetson-TX2 tracked pedestrians, the image refresh rate reached 3-5 fps. In the test, subaerial pedestrian slowly moves to ensure that aerial camera can catch the target, let unmanned aerial vehicle follow aloft. In the next process, we switch the mode of the drone edge computing device randomly. Fig. 5 illustrates the test results. From the test results, it can be seen that the unmanned aerial vehicle can correctly track the ground target in the process of randomly switching the edge computing device.

By means of the distributed selection sending protocol, the optimal MEC and the optimal calculation data can be obtained under the conditions that the calculation capacity of the MEC is unknown, the cellular communication network of the unmanned aerial vehicle is unknown, and the size of the perception data is unknown.
Further, the unmanned aerial vehicle performs edge calculation on the mass data and is divided into three stages: data perception, data transmission and data processing, the data sensing stage is: at this stage, the drone is aimed at performing tasks with the sensing devices it carries; the airborne equipment classifies the data, performs local processing on the simple data, and sends the complex data to the GS through a special transmission channel; then, the GS adopts high-performance edge computing equipment to process the received data;
the data transmission stage is as follows: at this stage, the unmanned aerial vehicle establishes a plurality of communication channels, detects the communication channels, finds an idle channel and transmits data; the unmanned aerial vehicle preferentially establishes a transmission channel which can be directly connected to the ground sensor; if the drone cannot directly contact the ground sensor, it will search for nearby communicating drones and then create relay communications;
the data processing stage is as follows: at this stage, the GS processes the received perception data. Because the real-time property of data transmission is difficult to realize and time delay exists; therefore, in some cases, prediction needs to be performed on part of the data in the data processing process; and after data processing, transmitting the result back to the terminal unmanned aerial vehicle.
Furthermore, an air park is introduced into the fully autonomous unmanned aerial vehicle cellular network, the air park can work cooperatively with a Ground Station (GS) to provide service for unmanned aerial vehicles which cannot be recovered, and the unmanned aerial vehicle communication network is composed of a plurality of GSs and a plurality of unmanned aerial vehicles.
