[0002] As human technology continues to advance, the development and utilization of natural resources is also increasing. However, excessive exploitation and utilization of natural resources can severely damage the stability of the ecological environment, necessitating timely monitoring and management of the natural resource ecosystem. However, obtaining ecological monitoring data is difficult due to the harsh natural environment and complex terrain. Drones (UAVs), powered aircraft without human operators, enable drones and their payloads to reach their destinations and obtain effective data without endangering human safety. UAV payloads primarily include optical remote sensing, lidar remote sensing, and microwave remote sensing.

[0003] During drone ecological monitoring, the air-to-ground connection between the drone and the ground user receiver is established. The number of drones at different altitudes can vary during this air-to-ground connection. This can significantly interfere with the drone's ecological monitoring data, affecting its transmission path. Therefore, it's necessary to dynamically adjust the drone's flight altitude to achieve optimal communication. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1 , which shows a flow chart of a method for establishing a data transmission link of a drone for ecological monitoring provided by an embodiment of the present invention, the method comprising the following steps:

[0036] Step S001: Obtain the operating parameters of the ecological monitoring drone at different times.

[0037] It should be noted that during the process of UAV monitoring of the ecological environment, due to the relatively complex ecological and natural environment, various obstacles may appear during the flight of the UAV, hindering the data communication between the UAV and the ground users during the flight. If the UAV communication channel is affected by the interference of the natural environment, the UAV ground user receiving end will be unable to normally receive the UAV ecological monitoring message data. At this time, it is necessary to obtain the ecological monitoring message data of the UAV ground user receiving end.

[0038] The moment The ecological monitoring message data of the UAV ground user receiving end is recorded as ,in , , Respectively expressed in moment, The moment and The ecological monitoring message data of the drone ground user receiving end at each moment is collected. At the same time, for the convenience of calculation, it is also necessary to obtain the different drone flight altitudes and the number of drones at the same altitude, as well as the Euclidean distance between different drones at the same altitude plane, the Euclidean distance between the drone and the ground user receiving end, and the maximum transmission limit of the ecological monitoring drone.

[0039] Step S002: Obtain an ecological monitoring drone operating parameter sequence based on the ecological monitoring drone operating parameters at different times, and calculate the disturbance characteristic coefficient of the ecological monitoring message data of the ground user receiving end at different times based on the ecological monitoring drone operating parameter sequence.

[0040] It should be noted that during the UAV ecological monitoring process, due to changing weather conditions and the complex and diverse terrain of the ecological environment area, there are significant obstacles in the UAV and ground reception process. At the same time, when data is transmitted and communicated between a UAV and a ground user receiving end, other UAVs at different locations will cause significant interference to the transmitting UAV. In order to better calculate and analyze the changes in the state of the UAV ecological monitoring data at different times, the data at each different time is used as the starting point, and the UAV ground user receiving end ecological monitoring message data with a preset slice length is taken, which is recorded as the ecological monitoring UAV operating parameter sequence. For ease of calculation, the present invention sets the preset slice length to 128. In specific applications, the implementer can set it according to the specific situation.

[0041]

[0042] Where, Indicates the height The total number of drones in the horizontal plane of space, represents the normalization function, Indicates the The maximum value of the ecological monitoring message data received by the ground user of the drone under the preset slice length at the time, Indicates that at the time The average value of the three adjacent different ecological monitoring UAV operating parameter series data, represents the DTW distance between two different sequences, Indicates that at the time At a height of The disturbance characteristic coefficient of the ecological monitoring message data received by the ground user of the UAV is obtained.

[0043] The time can be calculated by the above formula Height The disturbance characteristic coefficient of the ecological monitoring message data of the UAV ground user receiving end under the condition of Height The more UAVs there are under the control of the user, the larger the DTW value between the ecological monitoring message data sequences of the UAV ground user receiving end in multiple consecutive shorter preset slice lengths and the longer the DTW value between the ecological monitoring message data sequences of the user ground user receiving end is. The larger the maximum value of the message data at a moment, the smaller the average value. Height at each moment The more serious the interference is during the communication process of the UAV ecological monitoring data under the condition of the UAV, the disturbance characteristic coefficient of the ecological monitoring message data at the receiving end of the UAV ground user is calculated. The value will also be relatively large.

[0044] In step S003, the drones that communicate with the ground user receiving end at different times are recorded as ecological monitoring communication drones, and the remaining drones are recorded as ecological monitoring communication interference drones. The drone distribution space is obtained according to the operating parameters of the ecological monitoring drones at different times. The air-ground space distance between the ecological monitoring communication drone and the ground user receiving end is calculated according to the operating parameters of the ecological monitoring drones in the drone distribution space at different times. The flight space distance between the ecological monitoring communication drone and the ecological monitoring communication interference drone is calculated according to the operating parameters of the ecological monitoring drones in the drone distribution space at different times. The dynamic communication quality parameters of different ecological monitoring drones at different times are calculated according to the disturbance characteristic coefficient, air-ground space distance and flight space distance at different times.

[0045] It should be noted that during drone ecological monitoring, due to the relatively complex natural environment, multiple drones are used to monitor the environment to ensure that the overall ecological environment changes are captured. If multiple drones are operating at the same altitude, significant signal interference may occur during the transmission of ecological monitoring messages between these different drones and the same ground user receiver, resulting in data anomalies in the drone ecological monitoring data. Therefore, further analysis is required based on the length of the dynamic change interval of the ecological monitoring message data at the ground user receiver at different times.

[0046] Specifically, if Figure 2 As shown, assuming that at the current moment The drone's flight altitude is , and assuming that the maximum transmission distance of the drone is , then taking the drone ground user receiving terminal at the current moment as the center and the drone's maximum transmission distance as the radius, the drone distribution space at the current moment can be obtained. Indicates the The flying altitude of the UAV at the time is The ground user receiving terminal position at time Indicates the The flying altitude of the UAV at the time is Current ecological monitoring communication drone location, , , Respectively expressed The flying altitude of the UAV at the time is Time , and The position of the ecological monitoring communication interference drone is determined. Combining the distribution space of drones at different altitudes at different times, the distribution distance of drones at different positions in the space can be dynamically calculated.

[0047]

[0048]

[0049] Where, Indicates the The moment The Euclidean distance between an ecological monitoring communication drone and the ground user receiving end, Indicates the The flight altitude of the drone at the time Indicates the The moment The air-ground distance between an ecological monitoring communication UAV and the ground user receiving terminal, Indicates the The moment The first ecological monitoring communication drone and the The Euclidean distance between ecological monitoring communication interference drones, Indicates the The moment The first ecological monitoring communication drone and the The flight space distance between ecological monitoring communication interference drones.

[0050] Normally, if the current ecological monitoring communication drone The closer the distribution distance between the ground user receiving end is, and the farther the distribution distance between the other ecological monitoring communication interference drones and the ecological monitoring communication drones is, the higher the ecological monitoring data transmission quality of the ecological monitoring drones in the drone distribution space at the corresponding height is.

[0051] It should be noted that due to the large changes in the number of drone distribution during the flight of drones at different altitudes, the distribution density of ecological monitoring interference drones at different altitudes is different. At this time, the data communication between the ecological monitoring communication drone and the ground user receiving end will also be affected by greater interference. Therefore, it is necessary to analyze the distribution communication status of drones at the current altitude in combination with the data status of the drone ecological monitoring message at different times.

[0052]

[0053] In the above formula, Indicates that at the time At a height of The disturbance characteristic coefficient of the ecological monitoring message data received by the ground user of the UAV is Indicates that at the time Place The air-ground distance between an ecological monitoring communication UAV and the ground user receiving terminal, represents an exponential function with a natural constant as its base, Indicates the height The total number of drones in the horizontal plane of space, Indicates the The moment The first ecological monitoring communication drone and the The flight space distance between the ecological monitoring communication interference drones, Indicates the The height at this moment is The first Dynamic communication quality parameters of ecological monitoring drones.

[0054] The above formula can be used to calculate the At the height of Next Dynamic communication quality parameters of ecological monitoring drones at all times The height is In the drone space, if the ecological monitoring communication interference drone interferes with the unmanned data transmission process more seriously, the moment obtained is The dynamic data change interval length of the ecological monitoring message of the ground user receiving end of the drone with the preset slice length at the position will be relatively larger. If the spatial distance between the ecological monitoring drone and the ground user receiving end is closer in the corresponding altitude space, at the same time, different ecological monitoring communication interferences will occur between the drone and the first The farther the distance between the ecological monitoring communication drones, the higher the calculated height. The larger the dynamic communication quality parameters of an ecological monitoring drone are, the greater the

[0055] It should be noted that in the air-ground connection established between the UAV and the ground user receiving end, the proportion of line-of-sight links in the UAV communication channel under the air-ground connection is relatively high, and the fading loss during the UAV wireless signal transmission process is more consistent with the Nakagami-m channel model.

[0056]

[0057] Where, Indicates the The height at this moment is The first Dynamic communication quality parameters of ecological monitoring drones, Indicates the The level amplitude of the ecological monitoring drone at each moment, represents the standard power variance of white noise, represents the gamma function, represents an exponential function with a natural constant as its base, Indicates the The moment The numerical value of the fading loss of an ecological monitoring drone.

[0058] The height can be calculated by the above formula Next The fading loss value of an ecological monitoring communication drone is Dynamic communication quality parameters calculated by an ecological monitoring communication drone The larger the value, the lower the The communication status between the ecological monitoring communication drone and the ground receiving end user is relatively good. The moment The fading loss value of an ecological monitoring drone should be relatively small.

[0059] Step S004: Calculate the fading loss values ​​of different ecological monitoring drones at different times according to the dynamic communication quality parameters of different ecological monitoring drones at different times, and select the ecological monitoring communication drone data transmission link according to the fading loss values ​​of the ecological monitoring drones.

[0060] In order to obtain the overall status of the ecological environment more comprehensively, multiple different drones are usually used to monitor the ecological environment area. Assuming that multiple different ecological monitoring communication drones are distributed at different altitudes, in order to avoid interference from other drones during the transmission of drone ecological monitoring communication data, the fading loss value of each drone at different altitudes at different times is calculated, and the drone with the smallest fading loss value at all altitudes is selected to form the ecological monitoring communication drone data transmission link, ensuring that the data transmission path interference of multiple different drones is minimized during the ecological monitoring process, and the ground user receiving end can obtain ecological monitoring data more accurately.

[0061] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
