Description

Technical Field

[0001] The embodiments of the present invention relate to the field of low-altitude flight technology, and in particular to a wireless private network communication system and configuration method, device, electronic equipment, storage medium and program for low-altitude aircraft. Background Technology

[0002] With the rapid development of the low-altitude economy, low-altitude aircraft are increasingly widely used in fields such as inspection, logistics, passenger transport, security, and surveying. The wireless communication system of low-altitude aircraft is its most important infrastructure, representing a highly specialized wireless communication network signal distribution system. Ensuring that drones can safely fly over densely populated areas and prevent unauthorized control, as well as responding to extreme situations such as power outages and satellite disconnections, are critical issues that urgently need to be addressed.

[0003] Currently, related technologies typically employ traditional communication methods such as 4G / 5G, WiFi (wireless network), radar, and satellite networks to build a network system for managing low-altitude aircraft flying in low-altitude airspace and construct a space-ground infrastructure suitable for low-altitude aircraft.

[0004] In the process of developing this invention, the inventors discovered the following shortcomings in existing technologies: Traditional 4G / 5G cellular networks are primarily designed for terrestrial communication, with an effective coverage altitude of approximately 150 meters, which is insufficient to meet the communication needs of low-altitude airspace above 300 meters. Low-altitude information networks, however, require comprehensive air coverage. Furthermore, traditional 4G / 5G cellular network signals are susceptible to interference, making it difficult to guarantee necessary real-time connectivity when low-altitude aircraft share mobile communication networks with traditional users. More importantly, public network communication built using cellular networks carries significant risks of information leakage and remote control, making it difficult to address these security vulnerabilities. Additionally, cellular network base stations are mainly deployed for densely populated ground users, but the infrastructure for low-altitude aircraft is often deployed in sparsely populated areas. Using existing cellular network base stations to build wireless communication systems for low-altitude aircraft results in discontinuous signal coverage along low-altitude flight paths; building new cellular network base stations for low-altitude aircraft wireless communication systems increases the construction cost. Satellite communication is easily affected by weather, suffers from time delays and low uplink transmission efficiency, cannot provide stable high-capacity circuit link communication guarantees, has poor signal stability, and is costly. Furthermore, in the event of three abnormal situations—power grid outage, fixed network outage, and satellite disconnection—the existing wireless communication systems built using traditional communication methods are prone to failure, leading to the malfunction of low-altitude aircraft control and making it difficult to maintain the normal operation of low-altitude aircraft.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0041] It should be noted that the terms "first," "second," "third," "fourth," and "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0042] Figure 1 This is a flowchart illustrating a method for configuring a wireless private network communication system for a low-altitude aircraft according to an embodiment of the present invention. This embodiment is applicable to configuring a dedicated wireless communication system for a low-altitude aircraft based on the aircraft's takeoff and landing point location information and the target wireless communication method used. This method can be executed by a wireless private network communication system configuration device for the low-altitude aircraft. This device can be implemented in software and / or hardware and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device, as long as it can execute the wireless private network communication system configuration method for the low-altitude aircraft. This embodiment of the present invention does not limit the specific type of electronic device. Accordingly, as... Figure 1 As shown, the method includes the following operations:

[0043] S110. Obtain the take-off and landing point location information of the low-altitude aircraft in the target ground area corresponding to the target flight area.

[0044] Low-altitude aircraft refer to aircraft operating in low-altitude airspace (typically below 1000 meters vertically, but extending to no more than 3000 meters depending on actual needs), primarily used for low-altitude flight activities in various scenarios such as carrying personnel, cargo, and other operations. For example, the types of low-altitude aircraft may include, but are not limited to, helicopters, drones, light aircraft, and special types of aircraft, as long as there is a need for low-altitude flight. This embodiment of the invention does not limit the specific type of low-altitude aircraft. The target flight area can be the area where the low-altitude aircraft performs flight operations. The target ground area can be the ground area included in the target flight area. The take-off and landing point of the low-altitude aircraft can be the location used for take-off and landing of the low-altitude aircraft. Optionally, the take-off and landing point can be set in various environments, such as rooftops, the ground, riverbanks, and lawns.

[0045] Before configuring a dedicated wireless communication system for low-altitude aircraft, the deployment location of the system can be selected first, thus determining the area to be configured as the deployment area. This deployment area can be divided into a target flight area and a target ground area. The target flight area is the area where the low-altitude aircraft will perform flight operations, while the target ground area is the corresponding ground area.

[0046] Optionally, based on the target ground area, the takeoff point (referred to as the takeoff point) for the low-altitude aircraft flying from the target ground area to the target flight area, and the landing point (referred to as the landing point) for the low-altitude aircraft flying from the target flight area to the target ground area can be configured to obtain the takeoff and landing point location information of the low-altitude aircraft. It is understood that multiple sets of takeoff and landing point location information can be configured in the target ground area as needed, and the embodiments of the present invention do not limit the number of takeoff and landing point location information configured in the target ground area.

[0047] Low-altitude aircraft also require a dedicated wireless module to communicate with a specific wireless communication system. Understandably, once the wireless communication system is configured in the target area, the low-altitude aircraft can take off from its takeoff point in the target ground area and fly within a specific low-altitude orbit to its corresponding landing point in the target ground area. During its flight within the target flight area, the low-altitude aircraft can communicate using the configured dedicated wireless communication system.

[0048] In this embodiment of the invention, the area in the target flight area where low-altitude aircraft are allowed to fly is referred to as the low-altitude orbit because low-altitude aircraft must fly in the target flight area in accordance with set rules, such as strictly performing flight tasks according to set time, flight path, flight speed, and avoidance rules to avoid collisions at the intersection of flight paths.

[0049] S120. Determine the target wireless communication method used when wireless communication is conducted between each base station device in the target ground area and the low-altitude aircraft, as well as between each base station device.

[0050] The target wireless communication method can be the wireless communication method used between the base station equipment and the low-altitude aircraft. Optionally, the wireless communication system of the low-altitude aircraft composed of various base station equipment can be an IP-free wireless communication system; the target wireless communication method can be an IP address-free wireless communication method, such as an adaptive narrowband and broadband coordinated wireless communication method. The so-called adaptive narrowband and broadband coordinated wireless communication method can be a way to combine broadband communication technology and narrowband communication technology to provide more comprehensive and efficient communication services.

[0051] Base station equipment is one of the key components in wireless communication networks, primarily used for communication and data transmission with low-altitude aircraft to achieve wireless communication coverage. The main functions of base station equipment include wireless signal transmission, data transmission, connection and handover management, and spectrum management.

[0052] Understandably, different target wireless communication methods between base station equipment and low-altitude aircraft will result in different spacing requirements between the base station equipment. Therefore, before configuring a dedicated wireless network for low-altitude aircraft within the target flight area, it is necessary to first determine the specific wireless communication method used between each base station equipment and the low-altitude aircraft in the target ground area. Based on this specific wireless communication method, the spacing between different base station equipment can be set. Optionally, to maintain uniformity and communication efficiency, the wireless communication method between each base station equipment can also be the same as the target wireless communication method used between the base station equipment and the low-altitude aircraft.

[0053] In an optional embodiment of the present invention, the transmission power of the base station device is less than or equal to a first preset threshold, and the energy consumption of the base station device is less than or equal to a second preset threshold; the base station device is equipped with a disc antenna, the gain of the disc antenna is less than or equal to a third preset threshold, and the disc antenna transmits signals from the target ground area to the target flight area.

[0054] The first, second, and third preset thresholds can be configured according to actual needs. For example, the first preset threshold can be 2 watts, the second preset threshold can be 1.5 degrees, and the third preset threshold can be 3 dB. This embodiment of the invention does not limit the specific values ​​of the first, second, and third preset thresholds.

[0055] To prevent base station equipment malfunctions during power outages, fixed-line outages, and road closures, and to improve the anti-interference capabilities of base station equipment, devices with low transmission power and energy consumption can be used. In a specific example, the transmission power of base station equipment used to build a wireless communication network for low-altitude aircraft is no more than 2 watts, and its energy consumption is less than 1.5 kWh / day. Base station equipment can also be equipped with energy storage modules and power generation modules. The power generation module can automatically convert available resources into electrical energy and store the converted electrical energy through the energy storage module to power the base station equipment. Because the energy consumption of the base station equipment is low, the energy storage and power generation modules configured within the base station equipment can meet its power needs without the need for an external power source. Simultaneously, due to the low transmission power of the base station equipment, the power generation requirement of the power generation module is also low. In this scenario, even if the power grid equipment experiences a power outage, the base station equipment can still supply power normally through its own power generation and energy storage modules, thus resolving the equipment shutdown fault caused by the power grid outage. In addition, since the base station equipment does not need to use fixed-line networks to provide wireless communication functions, nor does it use satellite communication to provide a wireless communication network environment, even if there are faults such as fixed-line network outages or satellite connection failures, it will not affect the normal communication function of the wireless communication network of the low-altitude aircraft.

[0056] Optionally, the power generation module can be a solar panel or solar cell, as long as it can generate electricity using natural resources and meet the power supply requirements of the base station equipment. This embodiment of the invention does not limit the specific power generation method of the power generation module.

[0057] The base station equipment can also be equipped with a cone-shaped antenna for transmitting wireless signals, and the gain of the cone-shaped antenna is no greater than 3dB. In order to meet the low-altitude airspace coverage requirements of low-altitude aircraft, the cone-shaped antenna can transmit signals from the target ground area to the target flight area, that is, the antenna aperture of the cone-shaped antenna transmits signals from the ground upwards.

[0058] Therefore, it is evident that the wireless communication network for low-altitude aircraft deployed within the target flight area exhibits a distinctly regional characteristic. It provides a safe and reliable wireless communication environment only for low-altitude aircraft within the target flight area, without needing to consider long distances or the curvature of the Earth. Within the target flight area, air tunnels can be divided in tiers (e.g., every 100 meters), and low-altitude aircraft are required to perform their flight missions within these tunnels according to regulations. Consequently, the wireless communication network for low-altitude aircraft deployed within the target flight area also possesses the linear characteristic of these air tunnels; the wireless signal weakens or even disappears outside of them. Therefore, the coverage target of the wireless communication network for low-altitude aircraft deployed within the target flight area is fundamentally different from the large-area comprehensive coverage target of operators' 5G-A (5G-Advanced, an evolution of fifth-generation mobile communication technology).

[0059] S130. Determine the number of base station devices deployed in the target ground area and their ground deployment locations based on the take-off and landing point location information and the target wireless communication method.

[0060] Accordingly, after determining the target wireless communication method used when communicating with the low-altitude aircraft, the specific ground layout locations of the base station equipment in the target ground area can be determined based on the pre-configured take-off and landing point location information and the target wireless communication method between the low-altitude aircraft and the base station equipment. This allows for the further counting of the number of ground layout locations of the base station equipment in the target ground area, thus completing the configuration process of the wireless private network for the low-altitude aircraft in the target flight area.

[0061] Understandably, once the specific ground layout locations of the base station equipment in the target ground area are determined, the strength of the low-altitude true altitude signal in the target flight area can be determined according to the corresponding ground layout locations of the base station equipment. Generally, the strength of the low-altitude true altitude signal in the target flight area after the base station equipment is deployed according to its specific ground layout locations in the target ground area can meet the requirements of low-altitude aircraft. If, after testing, the strength of the low-altitude true altitude signal in some areas of the target flight area does not meet the requirements of low-altitude aircraft, then the ground layout locations of the base station equipment in those areas of the target flight area can be optimized and updated.

[0062] Optionally, in addition to configuring multiple base station devices in the target ground area, a centralized control platform can also be configured. The centralized control platform can communicate with each base station device, delineate flight paths in the target flight area, and continuously track low-altitude aircraft and send various centralized control commands through the base station devices. For example, it can plan the flight paths of low-altitude aircraft and send the planning results to each aircraft so that they can execute flight missions according to the pre-planned flight paths. Furthermore, the centralized control platform can also issue various control commands to low-altitude aircraft performing flight missions as needed through each base station device.

[0063] Optionally, the flight path designated by the centralized control platform for the target flight area can be a one-way constant-speed flight path with the centerline as its trajectory. For example, it can be a flight path composed of circular aerial tubes with a radius of 50 meters, centered at points along the physical flight centerline. This embodiment of the invention does not limit the specific shape of the flight path designated for the target flight area. A one-way constant-speed flight path can be understood as: all low-altitude aircraft in the same direction within the same flight path can fly at the same speed, and overtaking is prohibited.

[0064] Optionally, if multiple base station devices are configured only in the target ground area without a centralized control platform, one or more base station devices with control authority can be used as a centralized control platform to send various centralized control commands to the low-altitude aircraft. This embodiment of the invention does not impose any limitations on this.

[0065] In this embodiment of the invention, to improve the security and reliability of communication between low-altitude aircraft, the target wireless communication method used between base station equipment and low-altitude aircraft, as well as among base station equipment, can be a wireless communication method without IP addresses. Correspondingly, the wireless communication system of the low-altitude aircraft can adopt a private network architecture without IP addresses. Cognitive radio technology can be used to dynamically share and schedule spectrum between base station equipment and low-altitude aircraft, thereby discovering and utilizing idle or underutilized spectrum resources in the target flight area and target ground area to achieve a secure and reliable wireless communication process. Thus, the various base station equipment deployed at their ground locations in the target ground area can form a super-secure and reliable private wireless network for use by the low-altitude aircraft. External forces cannot intrude into the low-altitude aircraft's private wireless network through the IP address of the wireless network to perform destructive actions, effectively preventing hacker attacks, interception, and physical tampering. This allows the private wireless network to provide one-to-one video communication and precise monitoring capabilities throughout the entire process for the low-altitude aircraft.

[0066] This invention, through obtaining the take-off and landing point location information of a low-altitude aircraft in the target ground area corresponding to the target flight area, and determining the target wireless communication method used for wireless communication between each base station device in the target ground area and the low-altitude aircraft, as well as among the base station devices themselves, determines the number and location of base station devices in the target ground area based on the take-off and landing point location information and the target wireless communication method. After determining the number and location of each base station device in the target ground area, each base station device can be deployed at its designated location in the target ground area corresponding to the target flight area, thereby constructing a dedicated wireless communication system for low-altitude aircraft. The wireless communication system constructed by the above-described configuration method for a dedicated wireless network communication system for low-altitude aircraft can solve the problems of high security risks, insufficient coverage, and susceptibility to failure under extreme conditions in existing low-altitude aircraft wireless communication systems. It can improve the safety and reliability of the communication environment for low-altitude aircraft, thereby improving the efficiency and safety of the control and communication process of low-altitude aircraft in low-altitude orbit.

[0067] Figure 2 This is a flowchart illustrating another method for configuring a wireless private network communication system for a low-altitude aircraft, as provided in this embodiment of the invention. This embodiment is a specific modification of the above-described embodiment, and provides various specific and selectable implementation methods for determining the number and location of base station equipment in the target ground area. Correspondingly, as... Figure 2 As shown, the method in this embodiment may include:

[0068] S210. Obtain the take-off and landing point location information of the low-altitude aircraft in the target ground area corresponding to the target flight area.

[0069] S220. Determine the target wireless communication method used when wireless communication occurs between each base station device in the target ground area and the low-altitude aircraft, as well as among the base station devices themselves. The target wireless communication method includes TDD-CDMA communication.

[0070] TDD-CDMA (Time Division Duplex-Code Division Multiple Access) is a communication method that combines Time Division Duplexing (TDD) and Code Division Multiple Access (CDMA) technologies. In TDD mode, uplink and downlink transmissions occur in different time slots. This mode can effectively utilize spectrum resources, especially excelling in asymmetric service scenarios. TDD distinguishes between uplink and downlink through time division, reducing the complexity of frequency planning. In CDMA mode, each user is assigned a unique spreading code. These spreading codes are used to modulate the user's signal, ensuring that signals from different users do not interfere with each other when transmitted on the same frequency. CDMA improves the capacity and interference resistance of wireless communication systems through spreading technology.

[0071] S230. Determine the distance limit range between the ground layout positions of each base station device according to the target time frame structure adopted by the TDD-CDMA communication method.

[0072] The target time frame structure can be the time frame structure used for wireless transmission based on TDD-CDMA communication, specifically configured to meet the requirements of low-altitude flight. The distance limitation range refers to the distance between two adjacent base station devices.

[0073] The target time frame structure used in TDD-CDMA communication can constrain a time slot and the number of low-altitude aircraft that can be controlled within a time frame, thereby constraining the effective communication distance of a time slot. Therefore, different target time frame structures in TDD-CDMA communication result in different distance limits between the ground layout locations of each base station. Thus, it is first necessary to determine and analyze the target time frame structure used in TDD-CDMA communication to determine the distance limits between the ground layout locations of each base station based on the analysis results.

[0074] In an optional embodiment of the present invention, determining the distance range between the ground layout locations of each base station device according to the target time frame structure adopted by the TDD-CDMA communication method may include: determining the number of low-altitude aircraft controlled in a single time slot according to the target time frame structure adopted by the TDD-CDMA communication method; determining the number of single-end protection chips in the time slot according to the number of low-altitude aircraft controlled in the single time slot in the target time frame structure; determining the non-line-of-sight propagation environment transmission distance according to the number of single-end protection chips in the time slot; and determining the distance limitation range between the ground layout locations of each base station device according to the non-line-of-sight propagation environment transmission distance.

[0075] The number of low-altitude aircraft controlled in a single time slot can be defined as the number of low-altitude aircraft that can be controlled in a single time slot within a time frame. The protection chip can be the type of chip used in CDMA technology to protect the signal, ensuring that the signal is not interfered with or erroneous during transmission. The transmission distance in a non-line-of-sight propagation environment can be the furthest transmission distance defined by a single time slot within the target time frame structure.

[0076] Typically, in TDD-CDMA communication, each 10 milliseconds constitutes a time frame structure, and a time frame structure can include 8 time slots (also known as sub-time frames). For each time slot, the composition structure of the time slot can be specifically configured according to the requirements of low-altitude flight, thereby determining the target time frame structure suitable for batch control and communication of low-altitude aircraft.

[0077] In a specific example, assuming the target time frame structure used in TDD-CDMA communication determines that the number of low-altitude aircraft controlled by a single time slot is 16, this means that one time slot in the target time frame structure can simultaneously control 16 low-altitude aircraft. Furthermore, the number of single-end protection chips in a time slot can be determined based on the number of low-altitude aircraft controlled by a single time slot in the target time frame structure. For example, if the number of low-altitude aircraft controlled by a single time slot is 16, then the number of single-end protection chips in a time slot should also be 16, determined by the number of low-altitude aircraft controlled by a single time slot in the target time frame structure.

[0078] Figure 3 This is a schematic diagram of a target time frame structure provided in an embodiment of the present invention. Figure 3As shown, continuing with the example above, assume that every 8 slots in a target time frame structure include 4 slots for uplink transmission and 4 slots for downlink transmission. Each slot can contain 1600 chips, with 16 guard chips at each end, meaning there are 16 guard chips at each end of the slot. There are also 32 beacon chips in the middle, so one slot can carry 768 + 768 = 1536 data packets. The beacon chips are used for identification and synchronization signals, ensuring that the receiver can correctly identify and process signals from different transmitters. Thus, one slot can simultaneously control the wireless communication transmission of 16 low-altitude aircraft.

[0079] After determining the number of single-ended protection chips in a time slot, the transmission distance in a non-line-of-sight (NLS) propagation environment can be determined based on this number. Furthermore, the distance limits between the ground-based locations of each base station can be determined based on this NLS propagation distance. Continuing with the example above, if the number of single-ended protection chips in a time slot is 16, typically one chip time (1 chip) corresponds to a wireless signal transmission distance of 234.375m in free space. Therefore, the allowable transmission distance for 16 protection chips is 3750m. Since the speed of light for 16 protection chips can travel 3.75 km, and current wireless communication systems can handle multipath propagation at twice the speed, the multipath processing capability of a wireless communication system is greater than 5 km. Therefore, the NLS propagation distance can be determined to be 5 km. Further, the upper limit of the distance limit between the ground-based locations of each base station can be determined based on the NLS propagation distance, and the lower limit of the distance limit between the ground-based locations of each base station can be configured as needed. It is understood that the smaller the distance between the base station devices, the higher the reliability of the provided wireless communication environment. However, to save on base station deployment costs, the distance between each base station device cannot be too small. Optionally, the lower limit of the distance limit between the ground layout locations of each base station device can be determined based on the difference between the transmission distance in the non-line-of-sight propagation environment and a set distance interval (such as 1 or 2 kilometers). For example, taking the above example, the distance limit between the ground layout locations of each base station device, determined based on the transmission distance in the non-line-of-sight propagation environment, can be between 3 and 5 kilometers.

[0080] S240. Determine the number of reference base station devices and the reference ground layout positions that match the take-off and landing point location information in the target ground area based on the take-off and landing point location information.

[0081] The reference base station equipment can be a base station configured according to the take-off and landing point location information of the low-altitude aircraft. The reference ground layout location can be the layout location of the reference base station equipment in the target ground area.

[0082] Understandably, to meet the takeoff and landing requirements of low-altitude aircraft, a reference base station can be deployed at each takeoff and landing point in the target ground area, based on the aircraft's location information. That is, one reference base station can be configured at each takeoff point, and one at each landing point. If the distance between the takeoff and landing points is too far, base station equipment can be deployed at points in between.

[0083] S250. Based on the distance limit between the ground layout locations of each of the base station devices and the reference ground layout location of the reference base station device, determine the number of non-reference base station devices and their ground layout locations in the target ground area.

[0084] Among them, non-reference base station equipment can be other base station equipment in the target ground area besides reference base station equipment.

[0085] After determining the number and location of the baseline base station equipment, the ground layout locations of non-base station equipment can be configured within the target ground area based on the area size and the distance limits between the ground layout locations of each base station. The configuration criterion for non-base station equipment is that the straight-line distance to adjacent base station equipment (which can be either non-base station or base station equipment) is within the specified distance limit. Optionally, a planar geometric algorithm can be used to determine the ground layout locations of non-base station equipment in the target ground area based on the distance limits between the ground layout locations of each base station and the baseline ground layout location of the base station equipment. The number of ground layout locations for each non-base station can then be counted to obtain the total number of non-base station equipment.

[0086] In an optional embodiment of the present invention, after determining the number of base station devices and their ground layout locations in the target ground area based on the take-off and landing point location information and the target wireless communication method, the method may further include: connecting the take-off and landing point locations within the target flight area to obtain a take-off and landing point connection line; extending the take-off and landing point connection line as a reference along a predetermined distance in a set direction to obtain a region associated with the take-off and landing point connection line; and optimizing the number of base station devices and their ground layout locations in the target ground area when the airspace signal-to-noise ratio of the region associated with the take-off and landing point connection line is determined to be less than a fourth threshold.

[0087] The set direction can be either the horizontal or vertical direction of the line connecting the takeoff and landing points. The preset distance can be set according to actual needs, for example, it can be 500 meters; however, this embodiment of the invention does not limit the specific value of the preset distance. The associated area of ​​the line connecting the takeoff and landing points can be a three-dimensional area extended by the line connecting the takeoff and landing points. The fourth threshold can be configured according to the wireless communication requirements of the low-altitude aircraft, for example, it can be 20 dB.

[0088] Figure 4 This is a schematic diagram illustrating the effect of a connection area between takeoff and landing points provided in an embodiment of the present invention. In a specific example, such as... Figure 4 As shown, assume point A(x) a ,y a Point B(x) is the takeoff point. b ,y b Taking point A as the landing point, a line is drawn connecting the takeoff and landing points (points A and B) within the target flight area to obtain the takeoff and landing point line. Further, using this takeoff and landing point line as a reference, a preset distance is extended in a set direction to obtain... Figure 4 The region associated with the take-off and landing points of the cuboid region shown is as follows. Optionally, the region associated with the take-off and landing points can be a cuboid region constructed with the take-off and landing point line as the center line of the base. The length of the region associated with the take-off and landing points can be the straight-line distance of the take-off and landing point line, the width can be 2000 meters, and the height can be 1000 meters, that is, it extends 1 kilometer horizontally to the left and right and vertically upward from the take-off and landing points.

[0089] To meet the wireless communication requirements of low-altitude aircraft, the airspace signal-to-noise ratio (SNR) of the associated area along the take-off and landing point lines can be configured to be greater than or equal to a fourth threshold, such as a SNR of 20 dB or greater. Therefore, after deploying base station equipment according to the number and location of the equipment in the target ground area, the SNR of each associated area along the take-off and landing point lines can be tested. If the SNR of the associated area is determined to be less than the fourth threshold, it indicates that some factors are affecting the signal quality of the base station equipment. In this case, the number and location of the base station equipment in the target ground area can be optimized. For example, additional base station equipment can be added within areas where the SNR of the associated area along the take-off and landing point lines is less than the fourth threshold, to ensure that the optimized wireless communication network can meet the wireless communication requirements of low-altitude aircraft.

[0090] The above technical solution, after acquiring the take-off and landing point location information of the low-altitude aircraft in the target ground area corresponding to the target flight area and determining the target wireless communication method used for wireless communication between each base station device and the low-altitude aircraft, as well as among the base station devices themselves, determines the distance limit range between the ground layout positions of each base station device based on the target time frame structure adopted by the TDD-CDMA communication method. This allows for the determination of the number and location of reference base station devices matching the take-off and landing point location information in the target ground area, and further, based on the distance limit range between the ground layout positions of each base station device and the reference ground layout positions of the reference base station devices, the number and location of non-reference base station devices in the target ground area are determined. This completes the personalized configuration and deployment of the wireless private network for the low-altitude aircraft, achieving efficient, low-cost, and fixed-area dynamic wireless communication coverage. It can solve many problems of existing low-altitude communication networks and ensure the safe flight of low-altitude aircraft.

[0091] Figure 5 This is a schematic diagram of a wireless private network communication system for a low-altitude aircraft provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the wireless private network communication system of the low-altitude aircraft is deployed in the target ground area corresponding to the target flight area; the wireless private network communication system of the low-altitude aircraft includes multiple base station devices 510; wherein:

[0092] The number and location of each base station device 510 in the target ground area are determined based on the take-off and landing point location information of the low-altitude aircraft in the target ground area and the target wireless communication method; wherein, the target wireless communication method is the communication method used when the base station device 510 communicates with the low-altitude aircraft and with each base station device 510; the wireless communication system of the low-altitude aircraft composed of each base station device 510 is an IP-free wireless communication system; the target wireless communication method is an IP-free wireless communication method.

[0093] It should be noted that, Figure 5 This is merely a schematic diagram of a wireless private network communication system for low-altitude aircraft. This embodiment of the invention does not limit the number of base station devices in the target ground area or their ground location in the wireless private network communication system for low-altitude aircraft.

[0094] Figure 6 This is a schematic diagram of a wireless private network communication system for a low-altitude aircraft provided in an embodiment of the present invention. In an optional embodiment of the present invention, such as... Figure 6As shown, the wireless private network communication system for low-altitude aircraft may further include a centralized control platform 520. Each base station device 510 communicates with the centralized control platform 520 wirelessly. The centralized control platform 520 can be used to delineate flight paths for the target flight area and send circuit connection control commands to the low-altitude aircraft via the base station devices 510. It can also continuously track the low-altitude aircraft via the base station devices 510. Optionally, the base station devices 510 can be adaptive 2-watt base station devices. The wireless communication network can provide low-latency two-way communication between the low-altitude aircraft and the centralized control platform 520.

[0095] Optionally, the flight path designated by the centralized control platform for the target flight area can be a one-way constant-speed flight path with the centerline as its trajectory. For example, it can be a flight path composed of circular aerial tubes with a radius of 50 meters, centered at points along the physical flight centerline. This embodiment of the invention does not limit the specific shape of the flight path designated for the target flight area. A one-way constant-speed flight path can be understood as: all low-altitude aircraft in the same direction within the same flight path can fly at the same speed, and overtaking is prohibited.

[0096] The centralized control platform 520 connects directly to the wireless private network communication system of the low-altitude aircraft. It can control each network element in the system using AI (Artificial Intelligence) computing power, possessing sufficient computing and storage capabilities. For example, the centralized control platform 520 can perform pre-flight path planning for each low-altitude aircraft. Combining geographical, meteorological, and flight regulation constraints of the target flight area, it comprehensively formulates flight paths based on takeoff and landing point pairs for each low-altitude aircraft and transmits these planned paths to the corresponding aircraft via the wireless private network communication system. Optionally, the flight path orbit can be constructed using GNSS (Global Navigation Satellite System) coordinates. Simultaneously, the centralized control platform 520 can also generate takeoff and landing schedules for each low-altitude aircraft and provides real-time positioning and video monitoring functions for the aircraft performing flight missions. Low-altitude aircraft need to fly according to the flight path (x, y, z) issued by the centralized control platform 520. The deviation between the real-time flight path and the preset flight path shall not exceed a set deviation threshold, such as 50 meters. When the deviation between the real-time flight path and the preset flight path exceeds the set deviation threshold, the centralized control platform 520 can automatically correct the deviation and, if necessary, land the low-altitude aircraft.

[0097] The centralized control platform 520 can perform comprehensive control procedures on the low-altitude orbits involved in the target flight area. For example, the centralized control platform 520 can control the low-altitude orbits involved in the target flight area using the following operations:

[0098] Step 1: The centralized control platform performs airspace layering for the target flight area.

[0099] Figure 7 This is a schematic diagram illustrating the effect of airspace layering in a target flight area according to an embodiment of the present invention. In a specific example, such as... Figure 7 As shown, the centralized control platform can be based on H0=0 (ground), H i+1 =H i The target flight area is divided into airspace layers using the +100, i=1:9 method. Optionally, the centralized control platform can uniquely identify each low-altitude aircraft based on a combination of its flight identifier and MAC (Media Access Control Address) address.

[0100] Step 2: The centralized control platform dynamically plans the airspace level H to which low-altitude aircraft with flight rights within the target flight area belong. i And based on the flight airspace hierarchy H i The takeoff and landing points included in this flight airspace level H i Low-altitude aircraft flying in the middle of the altitude are assigned a suitable takeoff point A(x). a ,y a ) and landing point B(x) b ,y b And delineate the physical flight centerline {(x,y,H) from takeoff point A to landing point B. i )}.

[0101] Figure 8 This is a schematic diagram illustrating the effect of planning the physical flight centerline of a low-altitude aircraft within a flight airspace hierarchy, as provided in an embodiment of the present invention. In a specific example, such as... Figure 8 As shown, suitable takeoff points A(x) are assigned to low-altitude aircraft permitted to fly in flight airspace level H2. a ,y a ) and landing point B(x) b ,y b And delineate the physical flight centerline {(x,y,H) from takeoff point A to landing point B. i The physical flight centerline spacing between different low-altitude aircraft in flight airspace level H2 must be greater than or equal to the physical flight centerline spacing threshold. For example, the physical flight centerline spacing threshold can be 200 meters, but this embodiment of the invention does not impose any limitation on this.

[0102] It should be noted that when there is no controlled airspace over the straight line from takeoff point A to landing point B, then H can be... i The line connecting points A and B on a plane serves as the physical flight centerline from A to B. When there is one or more controlled airspaces above the straight line from takeoff point A to landing point B, the centralized control platform can set several "virtual takeoff and landing points" for the low-altitude aircraft. These virtual takeoff and landing points can be understood as turning points to avoid controlled airspaces. The centralized control platform can instruct the low-altitude aircraft to continue flying at these virtual takeoff and landing points to avoid controlled airspaces, but this does not involve actual takeoff and landing maneuvers.

[0103] Figure 9 This is a schematic diagram illustrating the effect of determining virtual take-off and landing points in controlled airspace, provided by an embodiment of the present invention. In a specific example, such as... Figure 9 As shown, tangent lines can be drawn from takeoff point A and landing point B to the operating area where the control zone is located, and the intersection of the two tangent lines can be used as virtual takeoff and landing points.

[0104] Step 3: The centralized control platform calculates or queries the network for the virtual physical intersections of the flight paths of each low-altitude aircraft, that is, the intersections of the flight centerline with other flight centerlines on the same plane. These intersections can be called virtual intersections, which are used for subsequent dynamic planning of avoidance rules for low-altitude aircraft at virtual intersections.

[0105] Alternatively, low-altitude aircraft can be used to calculate or query the virtual physical intersection points of the flight paths of various low-altitude aircraft via the network, and then send the virtual physical intersection points to the centralized control platform.

[0106] Figure 10 This is a schematic diagram illustrating the effect of a virtual intersection of different physical flight centerlines within the same flight airspace level plane, as provided in an embodiment of the present invention. In a specific example, such as... Figure 10 As shown, within the same flight airspace level H2 plane, there may be a virtual physical intersection point E between different physical flight centerlines, namely straight line AB and straight line CD, at a certain moment. This virtual physical intersection point can be used as a virtual intersection between straight line AB and straight line CD.

[0107] Step 4: The centralized control platform transmits the set flight airspace level H via wireless communication network. i The physical flight centerline parameters, namely the coordinates of the flight start point, the coordinates of the flight end point, the coordinates of the virtual take-off and landing point (which can be empty), the virtual intersection of the physical flight centerline, and the flight speed v, are sent to the corresponding low-altitude aircraft.

[0108] Step 5: After takeoff, the low-altitude aircraft will follow the physical flight centerline {(x,y,H} planned by the centralized control platform. iThe aircraft performs flight missions at speeds v and v. Optionally, to ensure flight safety, low-altitude aircraft in the same direction may fly at the same speed, and overtaking is prohibited.

[0109] Step Six: The centralized control platform calculates the arrival time of each low-altitude aircraft at the virtual intersection and notifies other low-altitude aircraft arriving at the virtual intersection simultaneously via the wireless communication network to avoid the virtual intersection according to the set virtual intersection avoidance method.

[0110] For example, the virtual crossing avoidance method could be to pre-set a time and distance for a low-altitude aircraft in the right lane to fly downwards, and a pre-set time and distance for a low-altitude aircraft in the left lane to fly upwards, and after changing course and flying for a certain period of time, return to the original physical flight centerline to continue flying. Alternatively, the virtual crossing avoidance method could also pre-set a time and distance for a low-altitude aircraft to fly to the right, or pre-set a time and distance for a low-altitude aircraft to fly to the left, and after changing course and flying for a certain period of time, return to the original physical flight centerline to continue flying. For example, a low-altitude aircraft in the right lane could fly downwards 30 meters 3 seconds before reaching the virtual crossing, and a low-altitude aircraft in the left lane could fly upwards 30 meters 3 seconds before reaching the virtual crossing. Alternatively, a low-altitude aircraft could fly 50 meters to the right 3 seconds before reaching the virtual crossing and then return to its assigned track; or a low-altitude aircraft could fly 50 meters to the left 3 seconds before reaching the virtual crossing and then return to its assigned track. At the same time, the centralized control platform started video monitoring of the operation at the virtual intersection.

[0111] Therefore, the centralized control platform 520 can manage the low-altitude orbit of low-altitude aircraft in the target flight area according to the set orbital traffic rules, thereby ensuring air traffic safety and maintaining air traffic order in the target flight area.

[0112] Specifically, the centralized control platform 520 can request meteorological services to obtain pre-flight meteorological information. For example, pre-flight meteorological elements may include, but are not limited to, clouds (cloud base, cloud height, cloud thickness and extent), wind (wind direction and speed), icing (ice extent and type), visibility, air pressure, temperature, atmospheric density, and weather phenomena. It can also obtain weather warning information, such as, but not limited to, low visibility, low clouds, strong winds, low-level wind shear, cumulonimbus clouds, thunderstorms, hail, real-time weather conditions during flight, and other weather warnings. During the flight mission of the low-altitude aircraft, the centralized control platform 520 can obtain real-time weather information, such as real-time cloud cover, visibility, wind direction, wind speed, weather phenomena, precipitation, hail, and snowfall. It can also provide the low-altitude aircraft with destination ground weather reports and weather forecasts, including significant changes in meteorological elements at the destination one hour before and after arrival, as well as changes in low-altitude winds at the landing site, such as tornadoes, squall lines, sandstorms, freezing rain (freezing drizzle), cold waves, heavy rain, heavy snow, cloud cover, aircraft icing, and aircraft turbulence. It can also provide low-altitude weather conditions or trend maps of the target flight area for the low-altitude aircraft to refer to.

[0113] Meanwhile, the centralized control platform 520 can also adjust the take-off and landing points and flight paths in low-altitude orbit in real time during the flight of low-altitude aircraft. That is, it can replan the flight path based on unexpected situations encountered during flight, such as changes in terrain, weather, or unknown flight limitations. The flight path may be dynamically adjusted locally or the mission may be changed. The replanned flight path can still include the location information of the origin, virtual take-off and landing points, destination, flight altitude and speed, and the time period to be reached.

[0114] In an optional embodiment of the present invention, the target wireless communication method may include a TDD-CDMA communication method; the number and location of each base station device 510 in the target ground area are configured as follows: the distance limit range between the ground locations of each base station device is determined according to the target time frame structure adopted by the TDD-CDMA communication method; the number and location of the reference base station devices that match the take-off and landing point location information in the target ground area are determined according to the take-off and landing point location information; the number and location of the non-reference base station devices in the target ground area are determined according to the distance limit range between the ground locations of each base station device and the reference ground location of the reference base station devices.

[0115] Correspondingly, the centralized control platform and the low-altitude aircraft can achieve bidirectional low-latency, low-power, and robust communication through TDD-CDMA communication.

[0116] In an optional embodiment of the present invention, the distance limitation range between the ground layout locations of each base station device may be determined based on the target time frame structure adopted by the TDD-CDMA communication method in the following manner: determining the number of low-altitude aircraft controlled in a single time slot based on the target time frame structure adopted by the TDD-CDMA communication method; determining the number of single-end protection chips in the time slot based on the number of low-altitude aircraft controlled in the single time slot in the target time frame structure; determining the non-line-of-sight propagation environment transmission distance based on the number of single-end protection chips in the time slot; and determining the distance limitation range between the ground layout locations of each base station device based on the non-line-of-sight propagation environment transmission distance.

[0117] In an optional embodiment of the present invention, the transmission power of the base station device 510 is less than or equal to a first preset threshold, and the energy consumption of the base station device 510 is less than or equal to a second preset threshold; the base station device 510 is equipped with a cone-shaped antenna, the gain of the cone-shaped antenna is less than or equal to a third preset threshold, and the cone-shaped antenna transmits signals from the target ground area to the target flight area. That is, the aperture of the cone-shaped antenna faces upward.

[0118] In an optional embodiment of the present invention, the airspace signal-to-noise ratio of the associated region formed by connecting the take-off and landing points within the target flight area is greater than or equal to a fourth threshold.

[0119] In an optional embodiment of the present invention, if the spatial signal-to-noise ratio of the area associated with the take-off and landing points is determined to be less than the fourth threshold, the number of base station devices 510 deployed in the target ground area and the ground deployment location are re-optimized.

[0120] Therefore, the aforementioned wireless private network communication system for low-altitude aircraft supports airspace signal coverage for low-altitude aircraft and can provide circuit-link data links. The wireless private network communication system uses TDD-CDMA communication for control and scheduling, forming a physically isolated network that ensures the security and stability of airspace communication, without relying on the power grid or fixed network, and is low-cost. The wireless private network communication system built using adaptive self-organizing network technology can reduce the power consumption of communication equipment, ensuring normal operation of airspace control even under extreme conditions of power outages, fiber optic cable outages, and road outages. Furthermore, by constructing low-altitude orbital aerial tunnels, virtual take-off and landing points, virtual intersections, and centrally controlled traffic rules, intelligent airspace centralized management is achieved, ensuring the safe passage of UAVs at orbital intersections and guaranteeing the navigation safety of low-altitude aircraft.

[0121] This invention, through obtaining the take-off and landing point location information of a low-altitude aircraft in the target ground area corresponding to the target flight area, and determining the target wireless communication method used for wireless communication between each base station device and the low-altitude aircraft, as well as among the base station devices themselves, in the target ground area, determines the number and location of base station devices in the target ground area based on the take-off and landing point location information and the target wireless communication method. After determining the number and location of each base station device in the target ground area, each base station device can be deployed at its designated location in the target ground area corresponding to the target flight area, thereby constructing a dedicated wireless communication system for low-altitude aircraft. The wireless communication system constructed by the above-described configuration method for a dedicated wireless network communication system for low-altitude aircraft can solve the problems of high security risks, insufficient coverage, and susceptibility to failure under extreme conditions in existing low-altitude aircraft wireless communication systems. It can improve the safety and reliability of the communication environment for low-altitude aircraft, thereby improving the efficiency and safety of the control and communication process of low-altitude aircraft in low-altitude orbit.
