Abstract

The invention provides a civil unmanned aerial vehicle (UAV) air traffic control system and a method for realizing flight control on unmanned aerial vehicles by adopting the same, relates to the field of civil unmanned aerial vehicle air traffic control and solves the problems that no civil unmanned aerial vehicle air traffic control system is provided, and an existing communication network is small in coverage range. The civil unmanned aerial vehicle air traffic control system comprises a background management controller, a local base station and node units; each of the node units is correspondingly mounted on one unmanned aerial vehicle, corresponds to an ID and is used for identifying an identity of the corresponding unmanned aerial vehicle; the node units are used for communicating with controllers on the unmanned aerial vehicles in real time, and packing and transmitting unmanned aerial vehicle flight data to the local base station; the local base station is used for performing line planning and scheduling on the unmanned aerial vehicle corresponding to each of the node units within a management radius of the local base station and is also used for communicating with the background management controller; the background management controller is used for verifying the flight authorities of all the unmanned aerial vehicles. The civil unmanned aerial vehicle air traffic control system and the method provided by the invention are mainly used for management and control on the unmanned aerial vehicles.

Example Embodiment

[0023] Specific embodiment one: see figure 1 To explain this embodiment, the civil UAV air traffic control system described in this embodiment includes a background management controller 1, a local base station 2 and a node unit 3;

[0024] Each node unit 3 is correspondingly installed on a drone, and each node unit 3 is correspondingly provided with an identity ID for identifying the identity of the drone to which it belongs;

[0025] The node unit 3 is used to communicate with the controller on the drone in real time, and after packaging the acquired flight data of the drone, it is sent from the communication link to the local base station 2;

[0026] The local base station 2 is used to plan and schedule the UAV corresponding to each node unit 3 within its management radius. It is also used to communicate with the background management controller 1 to transmit the UAV flight data to In the database of the background management controller 1;

[0027] The background management controller 1 is used to verify the flight authority of all drones, and according to the verification result, sends a base station control frame to control the local base station 2.

[0028] In this embodiment, the air traffic control node unit carried on the drone is physically independent of the drone controller, and a wired bus is used for data communication between the two. The controller on the drone can use some kind of fault-tolerant control such as FDI control It transmits the status of the drone to the node unit periodically and in time. When the flying status of the drone is abnormal, the node unit can send the abnormality to the local base station.

[0029] Communication can use a specific frame protocol format to ensure that the system can effectively monitor a sufficient number of UAVs.

Example Embodiment

[0030] Specific implementation manner 2: see figure 1 To explain this embodiment, the difference between this embodiment and the civil UAV air traffic control system described in the first embodiment is that the communication link includes a 3G/4G network, a Mesh network, and a UHF radio frequency communication network.

[0031] In this embodiment, the communication modes between the node unit and the local base station are diversified. There are three physical layer communication links between the node unit and the local base station, which are 3G/4G network, mesh network (such as zigbee, etc.), UHF wireless radio frequency communication, which can be switched according to different applications, such as in towns The area can use 3G/4G mobile network, use mesh network when the mobile network signal is not good and the range is short, and use UHF radio frequency communication when the distance from the local base station is far.

[0032] For drones that are close to the base station, a mesh network (such as zigbee, etc.) can be used to transmit data. This network topology can realize the management of more drones, and nodes in the network that are closer to the base station and have better communication conditions According to the load situation, it adaptively acts as a coordinator to receive data from other nodes and forward it to the base station. This not only expands the management area of the base station to a certain extent, but also reduces the base station's pressure on concurrent reception events.

Example Embodiment

[0033] Specific implementation manner three: see figure 1 with figure 2 This embodiment is described. The difference between this embodiment and the civil UAV air traffic control system described in the first embodiment is that when the number of node units 3 within the management radius of the local base station 2 is greater than or equal to 3, the local The base station 2 sends the IDs of other node units 3 within the warning range of any node unit 3 within its management radius to any one of the node units 3, and establishes a routing table through the Mesh network, and the any node unit 3 directly receives Position information of other node units 3 within the warning range.
