Technical Field

[0001] This invention belongs to the technical field of airspace management, specifically involving a method for processing UAV spatial location data based on regional differentiation. This method provides a nationwide network connection service for unmanned aerial vehicles (UAVs), solving the data pointing problem when multiple regions simultaneously open UAV management policies and UAVs operate across regions. Furthermore, it decouples data partitioning from specific business operations, allowing regional management agencies to conduct professional and personalized management based on local policies after receiving UAV data, thus avoiding problems such as overlapping and ambiguous management. Background Technology

[0002] With the popularization of unmanned aerial vehicles (UAVs), more and more people are using them. Based on their functions, UAVs can be divided into recreational UAVs and functional UAVs. Recreational UAVs are used for things like taking pictures of scenery. Functional UAVs are used for things like agricultural UAVs for spraying pesticides, UAVs for assisting in traffic control, and police UAVs, etc. During the use of these UAVs, a problem arises: which airspaces are safe to enter and which airspaces are not allowed? Currently, most UAVs are controlled by manual judgment or by setting fixed routes.

[0003] Meanwhile, with the popularization of unmanned aerial vehicles (UAVs), the flight management of UAVs is also an urgent problem to be solved.

[0004] As the country gradually deepens its opening up of low-altitude airspace, developing the low-altitude economy has become an important tool for building a new national development pattern. Safety is the bottom line in developing the low-altitude economy. At this critical juncture of the transformation and leapfrog development of my country's low-altitude economy, there is a lack of reasonable planning and efficient supervision technologies to ensure flight safety and public safety on the basis of fully guaranteeing air defense security.

[0005] To address this, we developed a nationwide network connectivity service for unmanned aerial vehicles (UAVs), resolving data routing issues when multiple regions simultaneously implement UAV management policies and when UAVs operate across regions. Furthermore, this method, based on regional differentiation, decouples data partitioning from specific business operations, allowing regional management agencies to conduct professional and personalized management of UAV data according to local policies, thus avoiding issues such as overlapping and ambiguous management. Summary of the Invention

[0006] The purpose of this invention is to provide a method for processing UAV spatial location data based on regional differentiation. This method provides a nationwide network connection service for unmanned aerial vehicles (UAVs), solves the data pointing problem when multiple regions simultaneously open UAV management policies and UAVs operate across regions, and decouples data partitioning from specific business operations. After receiving UAV data, management agencies in each region can carry out professional and personalized management according to local policies, avoiding problems such as management overlap and ambiguity.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for processing spatial position data of unmanned aerial vehicles based on regional partitioning, comprising the following steps: 1) The unmanned aerial vehicle initiates a TCP connection to the access gateway through the operator's network to establish a two-way communication link; 2) The connection management in the access gateway provides TCP-Server services for the unmanned aerial vehicle (UAV), manages the TCP connection sessions established between the UAV and the access gateway, and processes uplink and downlink data transmissions; 3) The unmanned aerial vehicle transmits data in real time via TCP connection; 4) The protocol encoding and decoding in the access gateway provides data packet encryption and encoding / decoding services for unmanned aerial vehicles and regional management agencies, and encrypts and encodes / decodes the location data packets sent by the unmanned aerial vehicles and the downlink control data packets of the regional management agencies; 5) The location calculation in the access gateway provides real-time location calculation services for unmanned aerial vehicles, and performs real-time calculation of the latitude, longitude and altitude data contained in its location; 6) The data partitioning in the access gateway provides data partitioning services for unmanned aerial vehicles (UAVs) and regional management agencies, and partitions the data according to the geographical information of each region based on the location data sent by the UAVs. 7) The message routing in the access gateway provides message routing services between the unmanned aerial vehicle and the regional management agency. The message routing rule is: according to the data partition information, messages are routed to each regional management agency according to the regional division level. 8) After receiving the data from the unmanned aerial vehicle, the regional management agency will perform further business processing. After the business processing is completed, the agency will send downlink data after encoding it through the protocol encoding and decoding service in the access gateway based on the processing results.

[0008] Preferably, the method for processing unmanned aerial vehicle spatial position data based on regional partitioning, wherein the calculation principle and process of the partitioning are as follows: a) Based on regional or station data and other regional data, calculate the maximum and minimum latitude and longitude data of the area to form a rectangular boundary; then perform preliminary matching with the real-time position of the UAV to obtain the regional data related to the location of the UAV. b) Based on the regional data obtained in step a), the maximum and minimum latitude and longitude data of the region are calculated to form a rectangular boundary based on the regional boundary data; then, a preliminary matching is performed with the real-time position of the UAV to obtain the regional data related to the location of the UAV. c) Based on the regional data obtained in step b), and based on the regional boundary data, perform full calculation on the location data of the unmanned aerial vehicle (UAV) using the latitude and longitude data of the region to obtain the precise regional information of the UAV's location. d) After obtaining the precise regional data according to step c), perform reverse positioning to obtain the administrative information of the unmanned aerial vehicle's location, such as district, city, province, and China region information.

[0009] Preferably, in the method for processing unmanned aerial vehicle spatial location data based on regional partitioning, in step c), in order to solve the problem of data discontinuity caused by the unmanned aerial vehicle flying back and forth at the boundary of two regions during flight, the regional boundary coordinate data is usually converted into distance during calculation and its boundary is enlarged proportionally to form a shared management area.
