Description

Technical Field

[0001] This invention relates to the field of meteorological monitoring technology, and in particular to an intelligent interactive flight management method based on the BeiDou short message data link. Background Technology

[0002] Current aviation weather forecasts can be categorized based on their effective timeframe into nowcasts (also known as "current forecasts," i.e., weather forecasts for the next 3 hours), short-term forecasts (i.e., weather forecasts for the next 6, 9, 12, or 18 hours), and short-term forecasts (weather forecasts for the next 24-48 hours). However, for sudden, rapidly moving, severe, and highly destructive severe convective weather, if flight equipment cannot obtain meteorological information in a timely manner and take emergency response measures, it may lead to flight delays, cancellations, disruptions to flight equipment communication, damage to the aircraft, or even loss of control of the flight equipment, directly endangering passenger safety. Traditional flight control computers are ill-equipped to handle such emergencies in advance and provide rapid emergency response.

[0003] In the event of an emergency during flight, an aircraft may deviate from its flight path, such as due to pilot error, aircraft malfunction, or attack. If an aircraft deviates from its flight path and enters another country's airspace, it could face serious dangers such as being shot down. When an aircraft suddenly deviates, traditional flight control systems struggle to detect this deviation and cannot promptly inform ground control of the cause, potentially leading to severe consequences that endanger flight safety and reduce overall flight security. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent interactive flight management method based on the BeiDou short message data link.

[0005] This invention provides an intelligent interactive flight management method based on the BeiDou short message data link, comprising the following steps:

[0006] Step 1: The ground control center obtains the flight information of the flight device. The flight information includes at least the preset flight route of the flight device and the latitude and longitude information of the location of the flight device. The flight information is analyzed to determine whether the flight device is at the preset station or the preset flight route.

[0007] Step 2: The ground control center obtains real-time information of the flight device within the flight range associated with the preset station or preset route. The real-time information includes the position information of the flight device on the preset route and the real-time meteorological information associated with the current position.

[0008] Step 3: The ground command center sends the real-time weather information to the flight device. The flight device determines whether to take off or land and take emergency evasive action based on the real-time weather information, or whether to activate an emergency route.

[0009] The ground command center performs yaw analysis based on the acquired position information and sends the yaw analysis results to the flight device. The flight device, based on the yaw analysis results and the judgment results of the activated emergency route, sends the abnormal route deviation result to the ground command center for route confirmation.

[0010] The interaction information between the ground command center and the flight device is transmitted via BeiDou satellite short messages.

[0011] Furthermore, the real-time meteorological information includes:

[0012] With the predetermined arrival location as the center, obtain aviation weather forecasts for a preset area near the predetermined arrival location;

[0013] The predetermined arrival location is a preset terminal; or a location on a preset route that is to be reached within a preset time.

[0014] Furthermore, in step 3, the flight device determines whether to take off / land and take emergency evasive action based on the real-time weather information, specifically including:

[0015] The flight device determines whether takeoff and landing can be carried out based on the real-time meteorological information received from the takeoff and landing route of the preset airport and the real-time meteorological information of the area near the five-sided line and four-turn point of the takeoff and landing runway of the preset airport, combined with the takeoff and landing standards of the flight device. Based on the determination result, the takeoff and landing operation is carried out, and the determination result is sent to the ground command center.

[0016] If any of the above real-time meteorological information is hazardous meteorological information, the ground command center generates an alarm message and sends the alarm message to the pilot, flight commander and air traffic controller of the flight device;

[0017] The flight commander and air traffic controllers send the alarm information to the flight device for takeoff and landing guidance, and instruct the pilot to perform takeoff, landing and emergency evasive maneuvers for the flight device.

[0018] Furthermore, in step 3, the ground command center sends the real-time weather information to the flight device, and the flight device determines whether to activate the emergency flight route based on the real-time weather information, specifically including:

[0019] The flight device receives real-time meteorological information about a pre-defined fan-shaped area near the predetermined arrival location. The real-time meteorological information is hazardous meteorological information, and the pre-defined fan-shaped area is a hazardous meteorological area. Based on the hazardous meteorological area, it calculates an emergency flight route to obtain emergency flight route information for bypassing the hazardous meteorological area and sends the emergency flight route information to the ground command center.

[0020] The ground command center receives and confirms the emergency flight path information and sends it to the pilot of the flight device, instructing the pilot to perform emergency operations on the flight device.

[0021] Furthermore, step 3 also includes: if the hazardous weather area exceeds the preset fan-shaped area, the ground command center obtains extended real-time weather information based on the temporary weather information of the flight device in the preset semi-circular area near the predetermined arrival position, and sends the extended real-time weather information to the flight device, and the flight device recalculates the emergency route based on the received extended weather information.

[0022] Furthermore, the emergency route calculation method specifically involves comparing and analyzing data from the civil aviation database with user-defined waypoints, hazardous weather areas, route angle control data, and route altitude data, and obtaining emergency route information based on the comparison and analysis results.

[0023] Further, in step 3, the ground command center performs yaw analysis based on the acquired position information and sends the yaw analysis results to the flight device. The flight device, based on the yaw analysis results and the judgment result of activating the emergency route, sends the abnormal route deviation result to the ground command center for route confirmation, specifically including:

[0024] The ground control center obtains the position information on the preset flight path, compares and analyzes the position information with the current position information of the flight device, and determines whether the distance between the current position of the flight device and the position of the flight device on the preset flight path exceeds the preset range. When it exceeds the preset range, it outputs a yaw warning message and sends the yaw warning message to the flight device.

[0025] The pilot of the flight device receives a yaw warning message from the ground command center. Based on the yaw warning message and the judgment result of the activated emergency route, the pilot confirms whether the route deviation is abnormal. If the route deviation is abnormal, the flight device automatically plans a route to return to the original route. If the route deviation is confirmed, the ground command center sends the route deviation information to the flight device. The pilot of the flight device receives the route deviation information and performs the route deviation operation.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention enables the ground command center to acquire real-time information about the flight device within a flight range associated with a preset station or route. The ground command center then sends the real-time meteorological information to the flight device. Based on the real-time meteorological information, the flight device determines whether to perform takeoff / landing and emergency avoidance maneuvers, or whether to activate an emergency route. The ground command center performs yaw analysis based on the acquired position information and sends the yaw analysis results to the flight device. The flight device, based on the yaw analysis results and the determination to activate the emergency route, sends the abnormal route deviation result back to the ground command center for emergency route confirmation. This allows for intelligent information exchange between the ground command center and the flight device via BeiDou short message service, improving flight safety and operational efficiency.

[0037] To make the objectives, technical solutions, design methods, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0038] like Figures 1-8As shown, this invention provides an intelligent interactive flight management method based on the BeiDou short message data link, comprising the following steps:

[0039] Step 1: The ground control center obtains the flight information of the flight device. The flight information includes at least the preset flight route of the flight device and the latitude and longitude information of the location of the flight device. The flight information is analyzed to determine whether the flight device is at the preset station or the preset flight route.

[0040] Step 2: The ground control center obtains real-time information of the flight device within the flight range associated with the preset station or preset route. The real-time information includes the position information of the flight device on the preset route and the real-time meteorological information associated with the current position.

[0041] The real-time meteorological information includes: obtaining aviation meteorological forecasts for a preset area near the predetermined arrival location, centered on the predetermined arrival location; wherein the preset area near the predetermined arrival location includes a preset fan-shaped area and a preset semi-circular area, and the predetermined arrival location is a preset terminal; or a location on a preset flight route that will be reached within a preset time.

[0042] Step 3: The ground command center sends the real-time weather information to the flight device. The flight device determines whether to take off or land and take emergency evasive action based on the real-time weather information, or whether to activate an emergency route.

[0043] The ground command center performs yaw analysis based on the acquired position information and sends the yaw analysis results to the flight device. The flight device, based on the yaw analysis results and the judgment results of the activated emergency route, sends the abnormal route deviation result to the ground command center for route confirmation.

[0044] The communication information between the ground command center and the flight device is transmitted via BeiDou satellite short message service.

[0045] The ground command center sends the real-time weather information to the flight device, and the flight device determines whether to take off or land and take emergency evasive action based on the real-time weather information.

[0046] Specifically, this includes: the preset flight path of the flight device and the latitude and longitude information of the flight device's location; analyzing the flight information to determine whether the flight device is at a preset airport or a preset flight path; wherein, a radius of 50 kilometers around the take-off and landing airport is considered a preset airport; the ground control center obtains aviation weather forecasts for the area within 50 kilometers around the take-off and landing airport of the preset airport for one hour before and after take-off and landing; the flight device, based on the received real-time weather information on the take-off and landing flight path of the preset airport and the real-time weather information of the area near the five-sided line and four-turn point of the take-off and landing runway of the preset airport, combined with the take-off and landing standards of the flight device, determines whether take-off and landing are possible; based on the determination result, take-off and landing operations are performed; and the determination result is sent to the ground control center.

[0047] If any of the above real-time meteorological information is hazardous meteorological information, the ground command center generates an alarm message and sends the alarm message to the pilot, flight commander and air traffic controller of the flight device;

[0048] The flight commander and air traffic controller will send the alarm information to the flight device to provide take-off and landing guidance, and instruct the pilot to perform take-off, landing and emergency evasion operations of the flight device.

[0049] In step 3, the ground command center sends the real-time meteorological information to the flight device. The flight device determines whether to activate the emergency route based on the real-time meteorological information. Specifically, this includes: determining whether the flight device is on the preset route based on the preset route and the latitude, longitude, and altitude of the flight device's location; a preset fan-shaped area in front of the flight device and an upper altitude limit of 500 meters indicate that the flight device is on the preset route; the ground command center obtains the aviation meteorological forecast for the preset area near the predetermined arrival position and sends it to the flight device; the flight device receives the real-time meteorological information in the preset fan-shaped area near the predetermined arrival position, which is hazardous meteorological information, and the preset fan-shaped area is a hazardous meteorological area; it calculates the emergency route based on the hazardous meteorological area, obtains the emergency route information for bypassing the hazardous meteorological area, and sends the emergency route information to the ground command center.

[0050] The ground command center receives and confirms the emergency flight path information and sends it to the pilot of the flight device, instructing the pilot to perform emergency operations on the flight device until the flight device completely bypasses the danger zone and returns to the original flight path along the emergency flight path.

[0051] In specific implementation, the flight device determines whether to activate the emergency route based on the real-time meteorological information, including: 1) obtaining real-time meteorological information within a preset fan-shaped area ahead of the flight device from the ground command center every 10 minutes via the BeiDou short message data link. The calculation of the preset fan-shaped area includes using the current position of the flight device as the center, the line 'a' connecting the center to the expected location of the flight device one hour after flight as the radius, and the direction of line 'a' as the midline of the included angle of the fan. The included angle of the fan is 60°, and the height of the preset fan-shaped area is the upper limit of the flight device's altitude, 500 meters. A schematic diagram of the preset fan-shaped area is shown below. Figure 2 As shown;

[0052] 2) Calculation of the expected arrival location of the aircraft one hour later, specifically including: obtaining the current position of the flight device, current flight speed, planned flight speed of the route, current altitude of the flight device, and planned flight altitude of the expected arrival location; using the current flight speed, the planned flight speed of each segment, and the estimated time of each segment, and adding wind speed, air pressure, and altitude parameters, calculating the distance of each segment of the flight device's expected flight; and converting the latitude, longitude, and altitude data of the expected arrival location based on the distance of the current position of the flight device.

[0053] 3) Obtain real-time meteorological information for a pre-defined fan-shaped area in front of the flight device;

[0054] 4) The flight device receives real-time meteorological information about a pre-defined fan-shaped area near the predetermined arrival location. This real-time meteorological information is hazardous weather information, and the pre-defined fan-shaped area is a hazardous weather zone. Based on this hazardous weather zone, the device calculates an emergency flight path to bypass the hazardous weather zone and sends this emergency flight path information to the ground command center. Then, it returns to the original flight path, such as... Figures 6-7 As shown;

[0055] The hazardous weather area is abstracted: Based on the acquired aviation weather forecasts for the area ahead of the flight equipment, the hazardous weather area is analyzed horizontally and vertically, and transformed into 100×100 meter vector data. Each set of data includes latitude and longitude, minimum altitude, and maximum altitude, such as... Figure 3 The vector diagram shows the hazardous weather zone.

[0056] If the hazardous weather area exceeds the preset fan-shaped area, the ground command center obtains extended real-time weather information based on the temporary weather information of the flight device in the preset semi-circular area near the predetermined arrival position, and sends the extended real-time weather information to the flight device. The flight device then recalculates the emergency flight path based on the received extended weather information.

[0057] The ground command center receives and confirms the emergency flight path information and sends it to the pilot of the flight device, instructing the pilot to perform emergency operations on the flight device.

[0058] 5) The emergency route calculation method is as follows: the civil aviation database is compared and analyzed with user-defined waypoints, hazardous weather areas, route angle control data and route altitude data, and emergency route information is obtained based on the comparison and analysis results.

[0059] Specifically, by combining route angle control data and route altitude data of waypoints stored in the civil aviation database with user-defined route angle control data and route altitude data of waypoints, and considering hazardous weather areas, emergency routes are selected based on the route corresponding to waypoints stored in the civil aviation database that can quickly bypass hazardous weather areas. The emergency routes are pre-defined rectangular areas of approximately 10 kilometers (400 meters vertically and horizontally), with the closest distance between the edge of the area and the hazardous area being 10 kilometers. Figure 4 Emergency flight paths are shown in the horizontal airspace diagram; for certain meteorological areas, emergency flight paths can be planned from below or above, such as... Figure 5 Emergency flight routes in the three-dimensional airspace are shown;

[0060] like Figure 8 As shown, in step 3, the ground command center performs yaw analysis based on the acquired position information and sends the yaw analysis results to the flight device. The flight device, based on the yaw analysis results and the judgment result of activating the emergency route, sends the abnormal route deviation result to the ground command center for route confirmation, specifically including:

[0061] The ground control center obtains the position information on the preset flight path, compares and analyzes the position information with the current position information of the flight device, and determines whether the distance between the current position of the flight device and the position of the flight device on the preset flight path exceeds the preset range. When it exceeds the preset range, it outputs a yaw warning message and sends the yaw warning message to the flight device.

[0062] It should be noted that the ground command center obtains the position information on the preset route in real time, compares and analyzes the position information with the current position information of the flight device, and determines whether the distance between the current position of the flight device and the position of the flight device on the preset route exceeds the preset range. The route deviation calculation is performed every 5 minutes. When the flight device deviates from the current route by 10 nautical miles, a yaw warning message is output and sent to the flight device.

[0063] The pilot of the flight device receives a yaw warning message from the ground command center. Based on the yaw warning message and the result of the activated emergency route, the pilot determines whether the route deviation is abnormal. If the route deviation is abnormal, the pilot automatically plans a route to return the flight device to the original route. If the route deviation is confirmed, the ground command center sends the route deviation information to the flight device (once every minute, until the flight device returns to the preset route or the pilot of the flight device communicates with the ground command center via the Beidou short message data link and the ground command center confirms the deviation). The pilot of the flight device receives the route deviation information and performs the route deviation operation.

[0064] It is worth noting that this method uses BeiDou short message service to achieve intelligent information exchange between the information collected by the flight device and the ground command center. The ground command center acquires real-time information from the flight device within the flight range associated with a preset station or preset route. The ground command center sends the real-time meteorological information to the flight device, and the flight device determines whether to take off or land and take emergency evasive action, or whether to activate an emergency route, based on the real-time meteorological information. Yaw analysis is performed using the position information acquired by the ground command center, and the yaw analysis results are sent to the flight device. The flight device, based on the yaw analysis results and the determination to activate an emergency route, adjusts its flight path accordingly. The abnormal deviation result is sent to the ground command center for emergency route confirmation. This enables intelligent information exchange between the ground command center and the flight device via BeiDou short message service. When the flight device is on the preset route, extreme weather may suddenly occur ahead, affecting the normal flight of the flight device. When the flight device is at the preset station, it can take off and land and take emergency avoidance measures. The flight device can obtain real-time weather information in a timely manner. Based on the yaw analysis results and the judgment result of activating the emergency route, the flight device sends the abnormal deviation result to the ground command center for emergency route confirmation to avoid route deviation, thereby improving the flight safety and operational efficiency of the flight device.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
