Description

Technical Field

[0001] The present invention relates to the field of wireless communications, and in particular to a data processing method, device, and system in a wireless communication system. Background Art

[0002] Wireless communication refers to the technology of transmitting information between two or more points through radio waves or light waves without using cables or other conductors.

[0003] In the existing technology, the propagation of wireless communication signals is easily affected by the geographical environment. Generally, areas with less external magnetic field interference and open areas without obstacles are selected as wireless communication transceiver base stations, and the base station spacing is selected so that the signal receiver can clearly receive the wireless signal sent by the sender.

[0004] When weather conditions change and the propagation rate of wireless signals in the air is low, it is easy to cause the strength of the signal received by the receiver to be low, making it difficult for the receiver to accurately receive information. Summary of the Invention

[0005] In order to improve the stability of wireless communication, the present invention provides a data processing method, device and system in a wireless communication system.

[0006] In a first aspect, the present invention provides a data processing method in a wireless communication system, which adopts the following technical solution:

[0007] A data processing method in a wireless communication system, comprising:

[0008] Obtain communication data;

[0009] determining signal strength based on communication data;

[0010] Determine the relay location based on signal strength;

[0011] Get the transit strength based on the transit position and update the signal strength;

[0012] Determine the forwarding path based on the relay strength and signal strength;

[0013] Based on the determined forwarding path, the transit wind speed is obtained based on the transit position;

[0014] When the transit wind speed is higher than the preset hovering threshold, the transit wind direction is obtained based on the transit position;

[0015] Determine the offset position based on the transfer position, moving distance, moving direction, transfer wind speed and transfer wind direction;

[0016] Controlling a preset UAV to move to an offset position, and controlling the preset UAV to release a preset temporary device;

[0017] Control the preset sending device, transfer device and temporary device to send information in sequence according to the sending and receiving sequence;

[0018] Obtaining falling velocity based on a temporary device;

[0019] When the falling speed exceeds the preset anti-impact threshold, it is determined whether there is vegetation at the hovering position based on geographic information;

[0020] When vegetation exists at the hovering position, the vegetation type is determined based on the geographic information and the hovering position;

[0021] Determine vegetation height based on vegetation type and obtain fall time based on temporary devices;

[0022] Determine the falling height based on the falling time and falling speed;

[0023] When the height of the falling object is consistent with the height of the vegetation, the preset temporary device is controlled to deploy the preset buffer device.

[0024] By adopting the above technical solution, a temporary device is released through a drone to forward signals. After the temporary device is released from the drone, it is easily affected by gravity and wind speed, causing the falling speed of the temporary device to continue to increase. When the falling speed of the temporary device is too large, it is easy for the temporary device to be subjected to a large impact force when it lands, causing damage to the temporary device. At this time, check whether there is vegetation at the landing point of the temporary device, so that the buffer device is deployed when the temporary device contacts the vegetation to reduce the impact force on the temporary device and improve the stability of the temporary device.

[0025] Optionally, also include:

[0026] When there is vegetation at the hovering position, the difference between the falling height and the vegetation height is calculated and defined as the height difference;

[0027] Determine the contact velocity based on the height difference and the falling velocity;

[0028] Determine buffer thresholds based on vegetation type;

[0029] When the contact velocity is higher than the buffer threshold, the difference between the contact velocity and the buffer threshold is calculated and defined as the velocity difference;

[0030] Determine the extension length based on the speed difference;

[0031] When the height of the falling object is consistent with the height of the vegetation, the preset buffer device is deployed according to the preset temporary device of the extension length.

[0032] By adopting the above technical solution, different vegetation has different buffering capabilities for temporary devices. When the speed of the temporary device is too high and the buffering capacity of the vegetation for the temporary device is weak, it is easy for the temporary device to still have a high speed after being buffered by the vegetation. At this time, the speed of the temporary device when it contacts the vegetation is estimated, and the expanded length of the buffer device is appropriately adjusted according to the comparative relationship between the speed of the temporary device and the buffering capacity of the vegetation, thereby adjusting the buffering capacity of the buffer device and improving the stability of the use of the temporary device.

[0033] Optionally, the method for determining the transfer location includes:

[0034] Obtain communication data;

[0035] determining signal strength based on communication data;

[0036] When the signal strength is lower than the preset transmission threshold, the relay distance is determined based on the signal strength;

[0037] Determine the sending location and the receiving location based on the communication data;

[0038] Determine the transfer area based on the transfer distance, sending location, and receiving location;

[0039] Determine the transfer location based on the transfer area;

[0040] The preset sending device is controlled based on the sending position to send information to the transfer position, and the preset transfer device is controlled based on the transfer position to send information to the receiving position.

[0041] By adopting the above technical solution, when the strength of the wireless signal is low, a suitable transfer device is selected according to the geographical relationship between the sender and the receiver, so that the signal is transferred through the transfer device, thereby improving the stability of wireless communication.

[0042] Optionally, the method for determining the transfer location further includes:

[0043] Retrieve geographic information based on transit areas;

[0044] Determine terrain height based on geographic information;

[0045] Determine the transfer height based on the transfer location and terrain height;

[0046] Determine the obstruction distance based on the transfer location, transfer height, and terrain height;

[0047] When the obstruction distance is higher than the preset propagation threshold, a transfer location is selected based on the obstruction distance.

[0048] By adopting the above technical solution, when there are multiple suitable transfer devices, the geographical situation of the location of the transfer device is retrieved, so as to select a transfer device with fewer surrounding obstacles, thereby reducing the situation where obstacles hinder wireless communication.

[0049] Optionally, the method for determining the forwarding path includes:

[0050] When the relay intensity is lower than the preset transmission threshold, the moving distance is determined according to the relay intensity;

[0051] Determine the moving direction based on the transfer location and the sending location;

[0052] When the signal strength is lower than the preset transmission threshold, the moving distance is determined based on the signal strength;

[0053] Determine the movement direction based on the credit location and transfer location;

[0054] Determine the forwarding path based on the moving distance and moving direction;

[0055] Control the movement of the preset drones according to the forwarding path, and determine the order of sending and receiving based on the relay strength and signal strength;

[0056] According to the order of sending and receiving, the preset sending device, transfer device and drone are controlled to send information in sequence.

[0057] By adopting the above technical solution, when the signal strength is still low after forwarding the signal through the relay device, a drone is dispatched from the relay device to the location where the signal is insufficient to forward the signal again, thereby improving the stability of wireless communication.

[0058] Optionally, the method for determining the forwarding path further includes:

[0059] When both the relay strength and the signal strength are lower than the preset transmission threshold, a correction difference is determined based on the relay strength;

[0060] Determine the correction distance based on the correction difference, the transfer position and the sending position;

[0061] Determine the correction area based on the correction distance, the sending position and the receiving position;

[0062] Determine the transfer location based on the correction area.

[0063] By adopting the above technical solution, when the signal strength received by the relay device and the receiver is low after forwarding the signal through the relay device, it means that the weather conditions have further deteriorated, resulting in a decrease in the propagation rate of the wireless signal. At this time, the relay device is reselected according to the propagation conditions of the wireless signal, thereby improving the stability of wireless communication.

[0064] Optionally, the method for determining the offset position includes:

[0065] When the transit wind speed is higher than the preset hovering threshold, the hovering position is determined based on the transit position, movement distance and movement direction;

[0066] Determine the hovering altitude based on the hovering position and terrain height;

[0067] Determine the offset distance based on the hovering altitude and the transit wind speed;

[0068] The offset position is determined based on the offset distance, transit wind direction and hovering position.

[0069] By adopting the above technical solution, when the wind speed is too high, it is difficult for the drone to hover stably, resulting in unstable signal strength of the drone. At this time, the drone releases a disposable temporary device at the hovering position, thereby forwarding the wireless signal through the temporary device, thereby improving the stability of wireless communication.

[0070] Optionally, the method for determining the offset position further includes:

[0071] When the offset distance is higher than the preset offset threshold, the difference between the offset distance and the offset threshold is calculated and defined as the offset difference;

[0072] Determine the horizontal throw speed based on the offset difference and the transit wind speed;

[0073] Determine the horizontal throw position based on the deviation threshold, the transit wind direction and the hovering position;

[0074] Control the preset drone to move to the horizontal throwing position, and control the preset drone to turn according to the transit wind direction;

[0075] The preset drone is controlled according to the horizontal throwing speed to eject the preset temporary device.

[0076] By adopting the above technical solution, when the wind speed is too high, the temporary device released from the drone is easily affected by the wind speed, resulting in a large horizontal speed when the temporary device lands, which in turn causes a large distance deviation between the temporary device's stopping point and the expected location. At this time, by giving the temporary device an initial speed opposite to the wind direction to reduce the speed of the temporary device when it lands, the stability of the temporary device in use is improved.

[0077] In a second aspect, the present application provides a data processing device in a wireless communication system, which adopts the following technical solution:

[0078] A data processing device in a wireless communication system includes a memory and a processor. The memory stores data that can be loaded and executed by the processor.

[0079] In a third aspect, the present application provides a data processing system in a wireless communication system, which adopts the following technical solution:

[0080] A data processing system in a wireless communication system, comprising:

[0081] An acquisition module is used to obtain communication data, transit intensity, transit wind speed, transit wind direction, falling speed and falling time;

[0082] A memory, configured to store any one of the above-mentioned data processing methods in a wireless communication system;

[0083] The processor can load and execute the program in the memory.

[0084] By adopting the above technical solution, a temporary device is released through a drone to forward signals. After the temporary device is released from the drone, it is easily affected by gravity and wind speed, causing the falling speed of the temporary device to continue to increase. When the falling speed of the temporary device is too large, it is easy for the temporary device to be subjected to a large impact force when it lands, causing damage to the temporary device. At this time, check whether there is vegetation at the landing point of the temporary device, so that the buffer device is deployed when the temporary device contacts the vegetation to reduce the impact force on the temporary device and improve the stability of the temporary device.

[0085] In summary, this application includes at least one of the following beneficial technical effects:

[0086] A temporary device is released by a drone to forward signals. After being released from the drone, it is susceptible to the effects of gravity and wind speed, causing the temporary device's falling speed to continue to increase. When the temporary device falls too fast, it is easy for it to be subjected to a large impact force when it lands, causing damage to the temporary device. At this time, check whether there is vegetation at the landing point of the temporary device, so that a buffer device can be deployed when the temporary device contacts the vegetation to reduce the impact force on the temporary device and improve the stability of the temporary device.

[0087] Different vegetation has different buffering capabilities for temporary devices. When the speed of the temporary device is too high and the buffering capacity of the vegetation is weak, it is easy for the temporary device to still have a high speed after being buffered by the vegetation. In this case, the speed of the temporary device when it contacts the vegetation is estimated, and the expansion length of the buffer device is appropriately adjusted according to the comparative relationship between the speed of the temporary device and the buffering capacity of the vegetation, thereby adjusting the buffering capacity of the buffer device and improving the stability of the temporary device.

[0088] When the strength of the wireless signal is low, a suitable relay device is selected according to the geographical relationship between the sender and the receiver, so that the signal is relayed through the relay device, thereby improving the stability of wireless communication.

[0097] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0098] An embodiment of the present application discloses a data processing method in a wireless communication system. The present application cooperates with a transfer device, a drone and a temporary device to forward wireless signals when the meteorological environment changes and causes interference to wireless communication, thereby improving the stability of wireless communication.

[0099] Reference Figure 1 , the method for determining the transfer location includes:

[0100] Step 100: Acquire communication data.

[0101] Communication data refers to the wireless communication signal received by the recipient. The method of obtaining communication data is selected by the staff according to the actual situation and will not be elaborated here.

[0102] Step 101: Determine signal strength based on communication data.

[0103] Signal strength refers to the strength value of communication data. The method for determining signal strength is common knowledge among those skilled in the art and will not be elaborated here.

[0104] Step 102: When the signal strength is lower than a preset transmission threshold, a transfer distance is determined according to the signal strength.

[0105] The transmission threshold is the minimum signal strength required for stable wireless communication. It is selected by personnel based on actual conditions and is not detailed here. A signal strength below the transmission threshold indicates that the communication data strength is too low, indicating unstable wireless communication.

[0106] The transit distance refers to the distance between the sender and receiver of communication data when the signal strength is equal to the transmission threshold. Wireless communication signals generally attenuate uniformly with distance. That is, the ratio of the transit distance to the distance between the sender and receiver is equal to the ratio of the transmission threshold to the signal strength. The distance between the sender and receiver can be read from the communication data, and the transit distance can be obtained by querying the distance data table. The distance data table refers to a data table that records different signal strengths and their corresponding transit distances.

[0107] Step 103: Determine the sending location and the receiving location based on the communication data.

[0108] The transmitting device refers to the device used to send communication data. The transmitting device is selected by the staff based on actual circumstances and is not described in detail here. The transmitting location is the location information of the transmitting device. The receiving location refers to the location information of the device used to receive communication data. The receiving location can be directly read from the device receiving the communication data. The transmitting location can be obtained by querying the transmitting data table. The distance between the sender and receiver mentioned above is the distance between the transmitting location and the receiving location. The transmitting data table is a data table that records different receiving locations and their corresponding transmitting locations.

[0109] Step 104: Determine the transfer area based on the transfer distance, the sending location, and the receiving location.

[0110] The transit area refers to the location interval that can stably receive signals from the sending location and send stable signals to the receiving location. The overlapping part of the areas with the sending location and the receiving location as the center and the transit distance as the radius can be used as the transit area. The method for determining the transit area is selected by the staff based on actual conditions and will not be elaborated here.

[0111] Step 105: Determine the transfer location according to the transfer area.

[0112] A transfer device is a device that receives communication data from a transmitting device and then forwards it to a receiving location. The transfer device is selected by staff based on actual circumstances and is not detailed here. A transfer location refers to the location of the transfer device. Generally, a transfer device near the center of the transfer area is preferred. The locations of transfer devices within the transfer area can be read from a transfer data table, and the location closest to the center of the transfer area is selected as the transfer location. A transfer data table is a table that records the locations of different transfer devices.

[0113] Step 106: Based on the sending location, control the preset sending device to send information to the transfer location, and based on the transfer location, control the preset transfer device to send information to the receiving location.

[0114] When the strength of the wireless signal is low, a transfer device close to the midpoint between the sender and the receiver is selected according to the geographical relationship between the sender and the receiver, so that the signal sent by the sending device is received by the transfer device and forwarded to the receiving location, thereby improving the stability of wireless communication.

[0115] Reference Figure 2 , the method for determining the transfer location also includes:

[0116] Step 107: Retrieve geographic information based on the transit area.

[0117] Geographic information refers to the geographical environment parameters within the transit area, including terrain height and vegetation coverage. The method of retrieving geographic information is selected by the staff based on actual conditions and will not be elaborated here.

[0118] Step 108: Determine the terrain height based on the geographic information.

[0119] The terrain height is the ground height value of each point in the transit area read from the geographic information. The method of reading the terrain height is selected by the staff according to the actual situation and will not be elaborated here.

[0120] Step 109: Determine the transfer height according to the transfer position and the terrain height.

[0121] The transfer height is the ground height of the transfer position. The method for determining the transfer height is selected by the staff based on actual conditions and will not be elaborated here.

[0122] Step 110: Determine the obstruction distance based on the transfer position, transfer height, and terrain height.

[0123] The obstruction distance refers to the distance between the transfer location and the point in the transfer area that is closest to the transfer location and is consistent with the transfer height. The method for determining the obstruction distance is common knowledge among people in this field and will not be described in detail here.

[0124] Step 111: When the obstruction distance is higher than a preset propagation threshold, a transfer location is selected according to the obstruction distance.

[0125] The propagation threshold is the minimum distance at which obstacles have minimal impact on the relay. The propagation threshold is selected by personnel based on actual conditions and is not detailed here. If the obstruction distance is higher than the propagation threshold, obstacles have minimal impact on the relay, meaning the relay is located in an open area. In this case, the relay location with the largest obstruction distance among the relay locations is selected.

[0126] Reference Figure 3 , the forwarding path determination method includes:

[0127] Step 200: Obtain the transit strength based on the transit position and update the signal strength.

[0128] The transfer strength refers to the strength value of the wireless communication signal received by the transfer device at the transfer location. The method for obtaining the transfer strength is selected by the staff according to the actual situation and will not be described in detail here.

[0129] Step 201: When the transfer intensity is lower than a preset transmission threshold, the moving distance is determined according to the transfer intensity.

[0130] The relay strength being lower than the transmission threshold indicates that the strength of the wireless communication signal received by the relay device from the transmitting device is too low, i.e., the wireless communication is unstable. The moving distance refers to the minimum distance required to move toward the transmitting device in order to stably receive the signal sent by the transmitting device. The moving distance can be obtained from the moving data table, which is a data table that records different signal strengths and their corresponding moving distances.

[0131] Step 202: Determine the moving direction according to the transfer location and the sending location.

[0132] A drone is a device installed on a relay device that relays wireless communication signals to stabilize communication between the relay device and the transmitting device or receiving location. The drone is selected by staff based on actual circumstances and is not detailed here. The movement direction refers to the direction the drone needs to move. When the strength of the wireless communication signal received by the relay device from the transmitting device is too low, the drone needs to move closer to the transmitting device, i.e., the direction from the relay location to the transmitting location is used as the movement direction. The method for determining the movement direction is selected by staff based on actual circumstances and is not detailed here.

[0133] Step 203: When the signal strength is lower than a preset transmission threshold, the moving distance is determined according to the signal strength.

[0134] If the signal strength is lower than the transmission threshold, it means that the strength of the wireless communication signal sent by the relay device to the receiving location is too low, that is, the wireless communication is unstable. At this time, the moving distance corresponding to the signal strength can be obtained from the movement data table.

[0135] Step 204: Determine the moving direction according to the authorized location and the transfer location.

[0136] When the strength of the wireless communication signal sent by the relay device to the receiving location is too low, the drone needs to move towards the receiving location, that is, the direction from the relay location to the receiving location is used as the moving direction.

[0137] Step 205: Determine a forwarding path according to the moving distance and the moving direction.

[0138] The forwarding path is the path that the UAV flies according to the moving distance and moving direction. The forwarding path can be automatically generated from the path generation program supporting the UAV. The production method of the forwarding path is common knowledge in this field and will not be elaborated here.

[0139] Step 206: Control the preset UAV movement according to the forwarding path, and determine the sending and receiving order according to the relay strength and signal strength.

[0140] The sending and receiving order refers to the order in which the sending device, the transfer device and the drone send and receive wireless communication data. When the transfer strength is lower than the transmission threshold, the drone is located between the sending device and the transfer device. At this time, the sending and receiving order is that the wireless communication data goes from the sending device to the drone, then to the transfer device, and finally to the receiving position. When the signal strength is lower than the transmission threshold, the drone is located between the receiving position and the transfer position. At this time, the sending and receiving order is that the wireless communication data goes from the sending device to the transfer device, then to the drone, and finally to the receiving position.

[0141] Step 207: Control the preset sending device, transfer device and drone to send information in sequence according to the sending and receiving order.

[0142] When the signal strength is still low after being forwarded by the relay device, a drone is dispatched from the relay device to the location where the signal is insufficient to forward the signal again, thereby improving the stability of wireless communication.

[0143] Reference Figure 4 , the method for determining the forwarding path further includes:

[0144] Step 208: When both the relay strength and the signal strength are lower than the preset transmission threshold, a correction difference is determined according to the relay strength.

[0145] If both the relay strength and the signal strength are lower than the transmission threshold, it means that the relay device cannot stably receive signals from the transmitting device or send stable signals to the receiving location, that is, the relay device is not located in the relay area, that is, the relay area has changed. The correction difference refers to the minimum distance the relay device needs to move to make the signal strength reach the transmission threshold. The correction difference corresponding to the relay strength can be obtained from the correction data table. The correction data table refers to a data table that records different signal strengths and their corresponding correction differences.

[0146] Step 209: Determine the corrected distance based on the corrected difference, the transfer position, and the sending position.

[0147] The corrected distance refers to the maximum distance at which the receiver can receive a signal that meets the transmission threshold in the current environment. You can first calculate the distance between the transfer location and the sending location, and then calculate the difference between the distance and the corrected difference as the corrected distance.

[0148] Step 210: Determine the correction area based on the correction distance, the sending location, and the receiving location.

[0149] The correction area is the area with the sending location and the receiving location as the center and the correction distance as the radius. The method for determining the correction area is selected by the staff based on the actual situation and will not be elaborated here.

[0150] Step 211: Determine the transfer location according to the corrected area.

[0151] The transfer position is the position of the transfer device selected from the correction area. First, the two closest adjacent position points in the two areas with the sending position and the receiving position as the center and the correction distance as the radius can be read, and then the position of the transfer device in the correction area can be read from the transfer data table. Finally, the position closest to the adjacent position point is selected as the transfer position.

[0152] When the signal strength received by the relay device and the receiver is low after the signal is forwarded through the relay device, it means that the weather conditions have further deteriorated, resulting in a decrease in the propagation rate of the wireless signal. At this time, the relay device is reselected according to the propagation conditions of the wireless signal, thereby improving the stability of wireless communication.

[0153] Reference Figure 5 , the offset position determination method includes

[0154] Step 212: Based on the determined forwarding path, the transfer wind speed is obtained based on the transfer position.

[0155] The transfer wind speed refers to the wind speed value of the environment in which the transfer device is located. The transfer wind speed can be obtained through a wind speed sensor. The method for obtaining the transfer wind speed is selected by the staff according to the actual situation and will not be elaborated here.

[0156] Step 213: When the transfer wind speed is higher than the preset hovering threshold, the hovering position is determined according to the transfer position, the moving distance and the moving direction.

[0157] The hovering threshold refers to the maximum wind speed at which the drone can hover stably. This threshold is determined by personnel based on actual conditions and is not detailed here. A transit wind speed exceeding the hovering threshold indicates that the wind speed is too high for the drone to hover stably. The hovering position is the position where the drone hovers. The hovering position is the position reached after moving from the transit position in the same direction and distance. The method for determining the hovering position is determined by personnel based on actual conditions and is not detailed here.

[0158] Step 214: Determine the hovering height according to the hovering position and the terrain height.

[0159] The hovering height refers to the height of the terrain at the hovering position. The method for determining the hovering height is common knowledge among those skilled in the art and will not be described in detail here.

[0160] Step 215: Obtain the transit wind direction based on the transit position.

[0161] The transfer wind direction refers to the wind direction angle value of the environment in which the transfer device is located. The transfer wind direction can be obtained by a wind direction sensor. The method for obtaining the transfer wind direction is selected by the staff according to the actual situation and will not be elaborated here.

[0162] Step 216: Determine the offset distance according to the hovering altitude and the transit wind speed.

[0163] A temporary device refers to a device mounted on a drone that is equipped with a wireless transceiver module and a buffer device for relaying signals. A buffer device refers to a device used to reduce the speed of the temporary device to reduce the impact force it receives when it lands. The buffer device can be a retractable metal strip on the temporary device. An anti-impact structure is provided between the metal strip and the temporary device. When the metal strip is impacted, the metal strip can be bent on the temporary device and restored when the metal strip is not impacted. The temporary device and buffer device are selected by the staff according to actual conditions and will not be elaborated here.

[0164] The offset distance refers to the horizontal distance between the temporary device and the hovering position after it is released from the drone and lands. After being released, the temporary device is easily moved horizontally due to the wind, and the horizontal movement time of the temporary device is affected by the hovering altitude. The offset distance can be obtained from the offset data table, which records the offset distances corresponding to different hovering altitudes and transit wind speeds.

[0165] Step 217: Determine the offset position according to the offset distance, the transit wind direction, and the hovering position.

[0166] The offset position refers to the position point where the temporary device needs to be released in order to offset the offset caused by the wind. The offset distance moved from the hovering position in the direction opposite to the transfer wind direction is the offset position. The method for determining the offset position is selected by the staff according to the actual situation and will not be elaborated here.

[0167] Step 218: Control the preset drone to move to the offset position, and control the preset drone to release the preset temporary device.

[0168] By adjusting the position where the drone releases the temporary device, the situation where the temporary device is affected by wind speed and causes the hovering position to deviate is offset, thereby improving the accuracy of the temporary device's landing point.

[0169] Step 219: Control the preset sending device, transfer device and temporary device to send information in sequence according to the sending and receiving sequence.

[0170] When the wind speed is too high, it is difficult for the drone to hover stably, resulting in unstable signal strength from the drone. At this time, the drone releases a one-time temporary device at the hovering position to forward the wireless signal, thereby improving the stability of wireless communication.

[0171] Reference Figure 6 , the method for determining the offset position also includes:

[0172] Step 220: When the offset distance is higher than a preset offset threshold, the difference between the offset distance and the offset threshold is calculated and defined as the offset difference.

[0173] The offset threshold refers to the offset distance corresponding to the maximum horizontal speed of the temporary device when it lands. The offset threshold is selected by staff based on actual conditions and is not detailed here. An offset distance exceeding the offset threshold indicates that the temporary device has moved too far horizontally, meaning that the horizontal speed of the temporary device at the time of landing is too high. The offset difference is the difference between the offset distance and the offset threshold, indicating whether the horizontal speed of the temporary device at the time of landing has exceeded the threshold.

[0174] Step 221: Determine the horizontal throw speed according to the offset difference and the transit wind speed.

[0175] The horizontal throw speed refers to the initial velocity value applied to the temporary device in the opposite direction of the transit wind when the drone releases the temporary device. The horizontal throw speed can be obtained from the horizontal throw data table, which records the horizontal throw speeds corresponding to different offset differences and transit wind speeds.

[0176] Step 222: Determine the horizontal throw position according to the offset threshold, the transit wind direction, and the hovering position.

[0177] The horizontal throw position refers to the position where the drone needs to release the temporary device after applying the horizontal throw speed to the temporary device so that the temporary device falls into the hovering position. The horizontal throw position is the position reached after moving the offset threshold in the direction opposite to the transit wind direction. The method for determining the horizontal throw position is selected by the staff according to the actual situation and will not be elaborated here.

[0178] Step 223: Control the preset UAV to move to the horizontal casting position, and control the preset UAV to turn according to the transit wind direction.

[0179] First, control the drone to reach the horizontal throwing position, and then control the drone to face the direction opposite to the transfer wind direction. The direction of the drone refers to the direction in which the drone releases the temporary device.

[0180] Step 224: Control the preset drone to eject the preset temporary device according to the horizontal throwing speed.

[0181] When the wind speed is too high, the temporary device released from the drone is easily affected by the wind speed, resulting in a large horizontal speed when the temporary device lands, which in turn causes a large distance deviation between the temporary device's stopping point and the expected location. At this time, by giving the temporary device an initial speed opposite to the wind direction to reduce the temporary device's landing speed, the stability of the temporary device can be improved.

[0182] Reference Figure 7 , a data processing method in a wireless communication system, comprising:

[0183] Step 300: Obtain falling velocity based on a temporary device.

[0184] The falling velocity refers to the speed value of the temporary device falling. The falling velocity can be obtained through the speed sensor in the temporary device. The method of obtaining the falling velocity is selected by the staff according to the actual situation and will not be elaborated here.

[0185] Step 301: When the falling speed is higher than a preset anti-impact threshold, it is determined whether there is vegetation at the hovering position based on geographic information.

[0186] The impact resistance threshold refers to the velocity corresponding to the maximum impact force that the temporary device can withstand. The impact resistance threshold is selected by personnel based on actual conditions and is not detailed here. A falling velocity exceeding the impact resistance threshold indicates that the temporary device is moving too fast, which can easily lead to excessive impact force upon impact, potentially damaging the temporary device. Geographic information can be used to extract vegetation coverage information at the hovering location to determine whether vegetation exists at the hovering location. Methods for determining vegetation coverage are common knowledge in this field and are not detailed here.

[0187] Step 302: When vegetation exists at the hovering position, the vegetation type is determined according to the geographic information and the hovering position.

[0188] The presence of vegetation at the hovering position means that the temporary device first contacts the vegetation during the falling process, that is, the temporary device can be buffered by the vegetation to reduce the falling speed. The vegetation type refers to the type of vegetation such as forest, shrub, grassland, etc. at the hovering position. The vegetation type can be read from the vegetation coverage information in the geographic information. The method for determining the vegetation type is common knowledge among people in this field and will not be elaborated here.

[0189] Step 303: Determine the vegetation height according to the vegetation type, and obtain the falling time based on the temporary device.

[0190] The vegetation height refers to the height of the vegetation at the hovering position. The vegetation height can be obtained from the vegetation data table. The vegetation data table refers to a data table that records different vegetation types and their corresponding vegetation heights.

[0191] The falling time refers to the length of time that has passed since the temporary device was released from the drone. The falling time can be obtained through the timer inside the temporary device. The method for obtaining the falling time is selected by the staff based on the actual situation and will not be elaborated here.

[0192] Step 304: Determine the falling height according to the falling time and falling speed.

[0193] The falling height refers to the height at which the temporary device is located. The falling height can be determined by calculating the falling time and falling speed. The method for calculating the falling height is common knowledge among people in this field and will not be described in detail here.

[0194] Step 305: When the height of the falling object is consistent with the height of the vegetation, the preset temporary device is controlled to deploy the preset buffer device.

[0195] The fact that the falling height is consistent with the height of the vegetation indicates that the temporary device is in contact with the vegetation. After the temporary device is released from the drone, it is susceptible to the effects of gravity and wind speed, causing the temporary device's falling speed to continue to increase. When the temporary device's falling speed is too high, it is easy for the temporary device to be subjected to a large impact force when it lands, causing damage to the temporary device. At this time, check whether there is vegetation at the landing point of the temporary device, so that when the temporary device contacts the vegetation, the buffer device is controlled to extend the metal bar to increase the contact area between the temporary device and the vegetation, thereby reducing the impact force on the temporary device and improving the stability of the temporary device.

[0196] Reference Figure 8 , a data processing method in a wireless communication system, further comprising:

[0197] Step 306: When there is vegetation at the hovering position, the difference between the height of the falling object and the height of the vegetation is calculated and defined as the height difference.

[0198] The height difference refers to the difference between the height of the temporary device and the height of the vegetation when the falling speed is equal to the anti-impact threshold. The height difference shows the distance between the temporary device and the vegetation when the falling speed is equal to the anti-impact threshold.

[0199] Step 307: Determine the contact velocity according to the height difference and the falling velocity.

[0200] The contact speed refers to the speed value when the temporary device contacts the vegetation. The contact speed can be determined by querying from the contact data table. The contact data table refers to a data table that records different height differences and falling speeds.

[0201] Step 308: Determine the buffer threshold according to the vegetation type.

[0202] The buffer threshold refers to the maximum speed value that vegetation can effectively buffer. The buffer threshold can be obtained from the threshold data table. The threshold data table refers to a data table that records different vegetation types and their corresponding buffer thresholds.

[0203] Step 309: When the contact speed is higher than the buffer threshold, the difference between the contact speed and the buffer threshold is calculated and defined as the speed difference.

[0204] A contact speed higher than the buffer threshold indicates that the temporary device is moving too fast when it contacts the vegetation. It is difficult to quickly reduce the speed of the temporary device using only the vegetation. The speed difference refers to the difference between the contact speed and the buffer threshold, and the speed difference indicates whether the temporary device's speed has exceeded the threshold.

[0205] Step 310: Determine the extension length according to the speed difference.

[0206] The extension length refers to the length of the buffer device extending out of the metal bar. The extension length can be determined from the extension data table. The extension length data table refers to a data table that records different speed differences and their corresponding extension lengths.

[0207] Step 311: When the height of the falling object is consistent with the height of the vegetation, the preset buffer device is deployed according to the preset temporary device of the extension length.

[0208] Different vegetation has different buffering capabilities for temporary devices. When the speed of the temporary device is too high and the buffering capacity of the vegetation is weak, it is easy for the temporary device to still have a high speed after being buffered by the vegetation. At this time, the speed of the temporary device when it contacts the vegetation is estimated, and the extension length of the buffer device is appropriately adjusted according to the comparative relationship between the speed of the temporary device and the buffering capacity of the vegetation, thereby increasing the contact area between the buffer device and the vegetation, thereby improving the buffering capacity of the buffer device and improving the stability of the use of the temporary device.
