Description

Technical Field

[0001] The present invention relates to the field of wireless communication, and more particularly 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 by means of radio waves or light waves without using cables or other conductors.

[0003] In the prior art, the propagation of wireless communication signals is easily interfered by the geographical environment. Generally, an area with less external magnetic field interference and no obstacles is selected as the transceiver base station for wireless communication, and the base station spacing is selected such that the signal receiver can clearly receive the wireless signal sent by the sender.

[0004] When the meteorological conditions change and the propagation rate of wireless signals in the air is low, it is easy to cause the signal received by the receiver to be weak, resulting in the situation that the receiver has difficulty in accurately receiving 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, adopting the following technical solution: A data processing method in a wireless communication system includes: Obtain communication data; Determine the signal strength according to the communication data; Determine the relay position according to the signal strength; Obtain the relay strength based on the relay position and update the signal strength; Determine the forwarding path according to the relay strength and the signal strength; Based on the determined forwarding path, obtain the relay wind speed based on the relay position; When the relay wind speed is higher than a preset hovering threshold, obtain the relay wind direction based on the relay position; Determine the offset position according to the relay position, moving distance, moving direction, relay wind speed and relay wind direction; Control a preset unmanned aerial vehicle to move to the offset position and control the preset unmanned aerial vehicle to release a preset temporary device; Control a preset transmitting device, relay device and temporary device to send information in sequence according to the transceiver sequence; Obtain the falling speed based on the temporary device; When the falling speed is higher than a preset anti-impact threshold, judge whether there is vegetation at the hovering position according to the geographical information; When there is vegetation at the hovering position, determine the vegetation type according to the geographical information and the hovering position; Determine the vegetation height according to the vegetation type, and obtain the falling time based on the temporary device; Determine the falling height according to the falling time and the falling speed; When the falling height is consistent with the vegetation height, control the preset temporary device to deploy the preset buffer device.

[0007] By adopting the above technical solution, a temporary device is released by a drone for signal forwarding. When the temporary device is released from the drone, it is easily affected by gravity and wind speed, resulting in a continuous increase in the falling speed of the temporary device. When the falling speed of the temporary device is too large, it is easy to cause the temporary device to be damaged due to a large impact force when it lands. At this time, check whether there is vegetation at the landing point of the temporary device, so as to deploy the buffer device when the temporary device contacts the vegetation to reduce the impact force received by the temporary device and improve the stability of the use of the temporary device.

[0008] Optionally, it further includes: When there is vegetation at the hovering position, calculate the difference between the falling height and the vegetation height, and define it as the height difference; Determine the contact speed according to the height difference and the falling speed; Determine the buffer threshold according to the vegetation type; When the contact speed is higher than the buffer threshold, calculate the difference between the contact speed and the buffer threshold, and define it as the speed difference; Determine the extension length according to the speed difference; When the falling height is consistent with the vegetation height, deploy the preset buffer device according to the extension length of the preset temporary device.

[0009] By adopting the above technical solution, different vegetation has different buffering capabilities for the temporary device. When the speed of the temporary device is too large and the buffering ability of the vegetation for the temporary device is weak, it is easy to cause the temporary device to still have a large speed after being buffered by the vegetation. At this time, estimate the speed when the temporary device contacts the vegetation, and appropriately adjust the deployment length of the buffer device according to the comparison relationship between the speed of the temporary device and the buffering ability of the vegetation, so as to adjust the buffering ability of the buffer device and improve the stability of the use of the temporary device.

[0010] Optionally, the method for determining the relay position includes: Obtain communication data; Determine the signal strength according to the communication data; When the signal strength is lower than the preset transmission threshold, determine the relay distance according to the signal strength; Determine the signal sending position and the signal receiving position based on the communication data; Determine the relay area according to the relay distance, the signal sending position and the signal receiving position; Determine the relay position according to the relay area; Based on the sending position, control the preset sending device to send information to the relay position, and based on the relay position, control the preset relay device to send information to the receiving position.

[0011] By adopting the above technical solution, when the intensity of the wireless signal is low, a suitable relay device is selected according to the geographical relationship between the sender and the receiver, so as to relay and send the signal through the relay device, thereby improving the stability of wireless communication.

[0012] Optionally, the method for determining the relay position further includes: Retrieve geographical information based on the relay area; Determine the terrain height according to the geographical information; Determine the relay height according to the relay position and the terrain height; Determine the obstacle distance according to the relay position, the relay height and the terrain height; When the obstacle distance is higher than the preset propagation threshold, select the relay position according to the obstacle distance.

[0013] By adopting the above technical solution, when there are multiple suitable relay devices, retrieve the geographical conditions of the locations where the relay devices are located, so as to select a relay device with fewer surrounding obstacles, thereby reducing the situation where obstacles hinder wireless communication.

[0014] Optionally, the method for determining the forwarding path includes: When the relay strength is lower than the preset transmission threshold, determine the moving distance according to the relay strength; Determine the moving direction according to the relay position and the sending position; When the signal strength is lower than the preset transmission threshold, determine the moving distance according to the signal strength; Determine the moving direction according to the receiving credit position and the relay position; Determine the forwarding path according to the moving distance and the moving direction; Control the preset unmanned aerial vehicle to move according to the forwarding path, and determine the sending and receiving order according to the relay strength and the signal strength; Control the preset sending device, relay device and unmanned aerial vehicle to send information in sequence according to the sending and receiving order.

[0015] By adopting the above technical solution, when the signal strength is still low after relaying the signal through the relay device, dispatch the unmanned aerial vehicle from the relay device to reach the position with insufficient signal to relay the signal again, thereby improving the stability of wireless communication.

[0016] Optionally, the method for determining the forwarding path further includes: When both the relay strength and the signal strength are lower than the preset transmission threshold, determine the correction difference according to the relay strength; Determine the correction distance according to the correction difference, the relay position and the signal - sending position; Determine the correction area according to the correction distance, the signal - sending position and the signal - receiving position; Determine the relay position according to the correction area.

[0017] By adopting the above - mentioned technical solution, when the signal strengths received by the relay device and the receiving party are both low after the signal is relayed by the relay device, it means that the meteorological conditions have further deteriorated, resulting in a decrease in the propagation rate of the wireless signal. At this time, the relay device is re - selected according to the propagation situation of the wireless signal, thereby improving the stability of wireless communication.

[0018] Optionally, the method for determining the offset position includes: When the relay wind speed is higher than the preset hovering threshold, determine the hovering position according to the relay position, the moving distance and the moving direction; Determine the hovering height according to the hovering position and the terrain height; Determine the offset distance according to the hovering height and the relay wind speed; Determine the offset position according to the offset distance, the relay wind direction and the hovering position.

[0019] By adopting the above - mentioned technical solution, when the wind speed is too high, it is difficult for the unmanned aerial vehicle to hover stably, resulting in an unstable signal strength of the signal relayed by the unmanned aerial vehicle. At this time, a disposable temporary device is released at the hovering position of the unmanned aerial vehicle, so as to relay the wireless signal through the temporary device, thereby improving the stability of wireless communication.

[0020] Optionally, the method for determining the offset position further includes: When the offset distance is higher than the preset offset threshold, calculate the difference between the offset distance and the offset threshold, and define it as the offset difference; Determine the horizontal throwing speed according to the offset difference and the relay wind speed; Determine the horizontal throwing position according to the offset threshold, the relay wind direction and the hovering position; Control the preset unmanned aerial vehicle to move to the horizontal throwing position, and control the preset unmanned aerial vehicle to turn according to the relay wind direction; Control the preset unmanned aerial vehicle to throw out the preset temporary device according to the horizontal throwing speed.

[0021] By adopting the above - mentioned technical solution, when the wind speed is too high, the temporary device released from the unmanned aerial vehicle is easily affected by the wind speed, resulting in a large horizontal speed when the temporary device lands, and further resulting in a large distance deviation between the landing point of the temporary device and the expected point. At this time, an initial speed opposite to the wind direction is given to the temporary device to reduce the speed of the temporary device when it lands, and improve the stability of the use of the temporary device.

[0022] In a second aspect, the present application provides a data processing device in a wireless communication system, adopting the following technical solution: A data processing device in a wireless communication system includes a memory and a processor. Stored on the memory is a data processing method for any of the above wireless communication systems that can be loaded and executed by the processor.

[0023] In a third aspect, the present application provides a data processing system in a wireless communication system, adopting the following technical solution: A data processing system in a wireless communication system includes: An acquisition module, configured to acquire communication data, relay strength, relay wind speed, relay wind direction, falling body speed, and falling body time; A memory, configured to store a data processing method for any of the above wireless communication systems; A processor, and the program in the memory can be loaded and executed by the processor.

[0024] By adopting the above technical solution, a temporary device is released by a drone for signal forwarding. When the temporary device is released from the drone, it is easily affected by gravity and wind speed, resulting in a continuous increase in the falling speed of the temporary device. When the falling speed of the temporary device is too large, it is likely to cause the temporary device to be damaged due to a large impact force when it lands. At this time, it is checked 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 received by the temporary device and improve the stability of the use of the temporary device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: By releasing a temporary device by a drone for signal forwarding, when the temporary device is released from the drone, it is easily affected by gravity and wind speed, resulting in a continuous increase in the falling speed of the temporary device. When the falling speed of the temporary device is too large, it is likely to cause the temporary device to be damaged due to a large impact force when it lands. At this time, it is checked 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 received by the temporary device and improve the stability of the use of the temporary device; The buffering capabilities of different vegetation for the temporary device are different. When the speed of the temporary device is too large and the buffering ability of the vegetation for the temporary device is weak, it is likely that the temporary device still has a large 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 deployment length of the buffer device is appropriately adjusted according to the comparison relationship between the speed of the temporary device and the buffering ability of the vegetation, thereby adjusting the buffering ability of the buffer device and improving the stability of the use of the temporary device; When the intensity of the wireless signal is low, a suitable relay device is selected according to the geographical relationship between the sender and the receiver, so as to relay and send the signal through the relay device, thereby improving the stability of wireless communication.

Detailed Implementation Modes

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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 used to limit the present invention.

[0028] The embodiments of the present application disclose a data processing method in a wireless communication system. The present application cooperates with a relay device, a drone and a temporary device, so as to forward wireless signals when the wireless communication is interfered due to changes in the meteorological environment, thereby improving the stability of wireless communication.

[0029] Referring to Figure 1 , the method for determining the relay position includes: Step 100: Obtain communication data.

[0030] The communication data refers to the wireless communication signal received by the receiver. The method for obtaining the communication data is selected by the staff according to the actual situation and will not be elaborated here.

[0031] Step 101: Determine the signal strength according to the communication data.

[0032] The signal strength refers to the strength value of communication data. The method for determining the signal strength is common knowledge to those skilled in the art and will not be elaborated here.

[0033] Step 102: When the signal strength is lower than the preset transmission threshold, determine the relay distance according to the signal strength.

[0034] The transmission threshold refers to the lowest signal strength at which stable wireless communication can be carried out. The transmission threshold is selected by the staff according to the actual situation and will not be elaborated here. That the signal strength is lower than the transmission threshold represents that the strength of the communication data is too low, that is, the wireless communication is unstable.

[0035] The relay distance refers to the distance between the sender and the receiver of the communication data when the signal strength is equal to the transmission threshold. Generally, the signal of wireless communication attenuates uniformly with distance, that is, the ratio of the relay distance to the distance between the sender and the receiver is equal to the ratio of the transmission threshold to the signal strength. The distance between the sender and the receiver can be read from the communication data, and the relay distance can be obtained by querying from the distance data table. The distance data table refers to the data table that records different signal strengths and their corresponding relay distances.

[0036] Step 103: Determine the signal sending position and the signal receiving position based on the communication data.

[0037] The signal sending device refers to the device used to send communication data. The signal sending device is selected by the staff according to the actual situation and will not be elaborated here. The signal sending position is the position information of the signal sending device, and the signal receiving position refers to the position information of the device used to receive communication data. The signal receiving position can be directly read from the device that receives the communication data, and the signal sending position can be obtained by querying from the signal sending data table. The above-mentioned distance between the sender and the receiver is the distance between the signal sending position and the signal receiving position. The signal sending data table refers to the data table that records different signal receiving positions and their corresponding signal sending positions.

[0038] Step 104: Determine the relay area according to the relay distance, the signal sending position and the signal receiving position.

[0039] The relay area refers to the position interval that can stably receive the signal from the signal sending position and can send a stable signal to the signal receiving position. The overlapping part of the areas with the signal sending position and the signal receiving position as the centers and the relay distance as the radius can be used as the relay area. The method for determining the relay area is selected by the staff according to the actual situation and will not be elaborated here.

[0040] Step 105: Determine the relay position according to the relay area.

[0041] A relay device refers to a device that receives communication data sent by a transmitting device and then forwards the communication data to the receiving location. The relay device is selected by the staff according to the actual situation and will not be elaborated here. The relay location refers to the location of the relay device. Generally, it is preferred to select the location of the relay device close to the center of the relay area as the relay location. The location of the relay device within the relay area can be read from the relay data table, and then the location closest to the center of the relay area is selected as the relay location. The relay data table refers to a data table that records the locations of different relay devices.

[0042] Step 106: Control a preset transmitting device to send information to the relay location based on the transmitting location, and control a preset relay device to send information to the receiving location based on the relay location.

[0043] When the intensity of the wireless signal is low, a relay 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 as to receive the signal sent by the transmitting device through the relay device and forward it to the receiving location, thereby improving the stability of wireless communication.

[0044] Refer to Figure 2 , the method for determining the relay location further includes: Step 107: Retrieve geographical information based on the relay area.

[0045] Geographical information refers to geographical environment parameters within the relay area, including terrain height and vegetation coverage, etc. The method for retrieving geographical information is selected by the staff according to the actual situation and will not be elaborated here.

[0046] Step 108: Determine the terrain height according to the geographical information.

[0047] The terrain height is the ground height value of each point within the relay area read from the geographical information. The method for reading the terrain height is selected by the staff according to the actual situation and will not be elaborated here.

[0048] Step 109: Determine the relay height according to the relay location and the terrain height.

[0049] The relay height is the ground height value of the relay location. The method for determining the relay height is selected by the staff according to the actual situation and will not be elaborated here.

[0050] Step 110: Determine the obstacle distance according to the relay location, the relay height and the terrain height.

[0051] The obstacle distance refers to the distance value between the position point closest to the relay location in the relay area with the same height as the relay height and the relay location. The method for determining the obstacle distance is common knowledge in the art and will not be elaborated here.

[0052] Step 111: When the obstruction distance is higher than a preset propagation threshold, select a relay position according to the obstruction distance.

[0053] The propagation threshold refers to the minimum obstruction distance at which the obstacle has a relatively small impact on the relay device. The propagation threshold is selected by the staff according to the actual situation and will not be elaborated here. That the obstruction distance is higher than the propagation threshold means that the obstacle has a relatively small impact on the relay device, that is, the location where the relay device is located is relatively open. At this time, select the relay position corresponding to the maximum obstruction distance among the relay positions.

[0054] Refer to Figure 3 , the method for determining the forwarding path includes: Step 200: Obtain the relay strength based on the relay position and update the signal strength.

[0055] The relay strength refers to the strength value of the wireless communication signal received by the relay device at the relay position. The method for obtaining the relay strength is selected by the staff according to the actual situation and will not be elaborated here.

[0056] Step 201: When the relay strength is lower than a preset transmission threshold, determine the moving distance according to the relay strength.

[0057] That the relay strength is lower than the transmission threshold means that the strength of the wireless communication signal received by the relay device from the transmitting device is too low, that is, the wireless communication is unstable. The moving distance refers to the minimum distance value that needs to be moved towards the transmitting device to stably receive the signal sent by the transmitting device. The moving distance can be obtained by querying the moving data table, which refers to the data table recording different signal strengths and their corresponding moving distances.

[0058] Step 202: Determine the moving direction according to the relay position and the transmitting position.

[0059] The drone refers to a device installed on the relay device for forwarding wireless communication signals to stabilize the communication between the relay device and the transmitting device or the receiving position. The drone is selected by the staff according to the actual situation and will not be elaborated here. The moving direction refers to the direction in which 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 towards the direction closer to the transmitting device, that is, take the direction from the relay position to the transmitting position as the moving direction. The method for determining the moving direction is selected by the staff according to the actual situation and will not be elaborated here.

[0060] Step 203: When the signal strength is lower than a preset transmission threshold, determine the moving distance according to the signal strength.

[0061] That the signal strength is lower than the transmission threshold means that the strength of the wireless communication signal sent by the relay device to the receiving position is too low, that is, the wireless communication is unstable. At this time, the moving distance corresponding to the signal strength can be obtained by querying the moving data table.

[0062] Step 204: Determine the moving direction according to the credit location and the transfer location.

[0063] When the intensity of the wireless communication signal sent by the transfer device to the receiving location is too low, the UAV needs to move in the direction closer to the receiving location, that is, the direction from the transfer location to the receiving location is taken as the moving direction.

[0064] Step 205: Determine the forwarding path according to the moving distance and the moving direction.

[0065] The forwarding path is the path for the UAV to fly according to the moving distance and the 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 for those skilled in the art and will not be elaborated here.

[0066] Step 206: Control the preset UAV to move according to the forwarding path, and determine the sending and receiving order according to the transfer intensity and the signal intensity.

[0067] The sending and receiving order refers to the order in which the sending device, the transfer device, and the UAV send and receive wireless communication data. When the transfer intensity is lower than the transmission threshold, the UAV is located between the sending device and the transfer device. At this time, the sending and receiving order is that the wireless communication data sequentially goes from the sending device to the UAV, then to the transfer device, and finally to the receiving location. When the signal intensity is lower than the transmission threshold, the UAV is located between the receiving location and the transfer location. At this time, the sending and receiving order is that the wireless communication data sequentially goes from the sending device to the transfer device, then to the UAV, and finally to the receiving location.

[0068] Step 207: Control the preset sending device, transfer device, and UAV to send information in sequence according to the sending and receiving order.

[0069] When there is still a situation of low signal intensity after forwarding the signal through the transfer device, dispatch the UAV from the transfer device to reach the location with insufficient signal to forward the signal again, so as to improve the stability of wireless communication.

[0070] Refer to Figure 4 , the method for determining the forwarding path further includes: Step 208: When both the transfer intensity and the signal intensity are lower than the preset transmission threshold, determine the correction difference according to the transfer intensity.

[0071] Both the relay strength and the signal strength being lower than the transmission threshold indicates that the relay device has difficulty in stably receiving signals from the transmitting device and also has difficulty in sending stable signals to the receiving location, that is, the relay device is not located within the relay area, that is, the relay area has changed. The correction difference is the minimum distance that the relay device needs to move to make the signal strength reach the transmission threshold, and the correction difference corresponding to the relay strength can be obtained by querying from the correction data table. The correction data table is a data table that records different signal strengths and their corresponding correction differences.

[0072] Step 209: Determine the correction distance according to the correction difference, the relay position, and the transmitting position.

[0073] The correction distance is the maximum distance at which the receiving party can receive signals at the transmission threshold in the current environment. First, the distance between the relay position and the transmitting position can be calculated, and then the difference between the distance and the correction difference can be calculated as the correction distance.

[0074] Step 210: Determine the correction area according to the correction distance, the transmitting position, and the receiving position.

[0075] The correction area is the area with the transmitting position and the receiving position as the centers and the correction distance as the radius respectively. The method for determining the correction area is selected by the staff according to the actual situation and will not be elaborated here.

[0076] Step 211: Determine the relay position according to the correction area.

[0077] The relay position is the position of the relay device selected from the correction area. First, the two closest adjacent position points in the two areas with the transmitting position and the receiving position as the centers and the correction distance as the radius can be read, and then the position of the relay device located within the correction area can be read from the relay data table. Finally, the position closest to the adjacent position points is selected as the relay position.

[0078] When the signal strengths received by the relay device and the receiving party are both low after the signal is relayed through the relay device, it indicates that the meteorological 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 situation of the wireless signal, so as to improve the stability of wireless communication.

[0079] Refer to Figure 5 , the method for determining the offset position includes Step 212: Based on the situation of determining the forwarding path, obtain the relay wind speed based on the relay position.

[0080] The relay wind speed is the wind speed value of the environment where the relay device is located. The relay wind speed can be obtained through a wind speed sensor. The method for obtaining the relay wind speed is selected by the staff according to the actual situation and will not be elaborated here.

[0081] Step 213: When the transfer wind speed is higher than the preset hovering threshold, determine the hovering position according to the transfer position, moving distance, and moving direction.

[0082] The hovering threshold refers to the maximum wind speed at which the UAV can stably hover. The hovering threshold is selected by the staff according to the actual situation and will not be elaborated here. When the transfer wind speed is higher than the hovering threshold, it means that the wind speed is too high at this time and it is difficult for the UAV to stably hover in the air. The hovering position refers to the position where the UAV hovers. The position reached after moving from the transfer position according to the moving direction and moving distance is the hovering position. The method for determining the hovering position is selected by the staff according to the actual situation and will not be elaborated here.

[0083] Step 214: Determine the hovering height according to the hovering position and the terrain height.

[0084] The hovering height refers to the height value of the terrain at the hovering position. The method for determining the hovering height is common knowledge for those skilled in the art and will not be elaborated here.

[0085] Step 215: Obtain the transfer wind direction based on the transfer position.

[0086] The transfer wind direction refers to the wind direction angle value of the environment where the transfer device is located. The transfer wind direction can be obtained by using 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.

[0087] Step 216: Determine the offset distance according to the hovering height and the transfer wind speed.

[0088] The temporary device refers to a device for relaying signals that is carried on the UAV and is equipped with a wireless transceiver module and a buffer device. The buffer device refers to a device used to reduce the speed of the temporary device to reduce the impact force when the temporary device lands. The buffer device can adopt a telescopic metal bar on the temporary device. An anti-impact structure is provided between the metal bar and the temporary device. When the metal bar is impacted, the metal bar can bend on the temporary device and return when the metal bar is not impacted. The temporary device and the buffer device are selected by the staff according to the actual situation and will not be elaborated here.

[0089] The offset distance refers to the distance value in the horizontal direction between the position where the temporary device is released from the UAV and lands and the hovering position. After the temporary device is released, it is easily moved in the horizontal direction under the influence of the wind, and the moving time of the temporary device in the horizontal direction is affected by the hovering height. The offset distance can be obtained by querying the offset data table. The offset data table refers to a table that records the offset distances corresponding to different hovering heights and transfer wind speeds.

[0090] Step 217: Determine the offset position according to the offset distance, the transfer wind direction, and the hovering position.

[0091] The offset position refers to the position point that needs to be released by the temporary device to offset the offset caused by the influence of wind force on the temporary device. Moving the offset distance 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.

[0092] Step 218: Control the preset unmanned aerial vehicle (UAV) to move to the offset position and control the preset UAV to release the preset temporary device.

[0093] By adjusting the position where the UAV releases the temporary device to offset the situation where the temporary device offsets from the hovering position due to the influence of wind speed, the accuracy of the landing point of the temporary device is improved.

[0094] Step 219: Control the preset signal transmitting device, transfer device, and temporary device to send information in sequence according to the receiving and transmitting order.

[0095] When the wind speed is too high, it is difficult for the UAV to hover stably, resulting in an unstable signal intensity transmitted by the UAV. At this time, a disposable temporary device is released by the UAV at the hovering position, so as to forward the wireless signal through the temporary device, thereby improving the stability of wireless communication.

[0096] Refer to Figure 6 , the method for determining the offset position also includes: Step 220: When the offset distance is higher than the preset offset threshold, calculate the difference between the offset distance and the offset threshold, and define it as the offset difference.

[0097] The offset threshold refers to the offset distance corresponding to the maximum horizontal speed when the temporary device lands. The offset threshold is selected by the staff according to the actual situation and will not be elaborated here. The offset distance being higher than the offset threshold means that the horizontal movement distance of the temporary device is too large, that is, the horizontal speed of the temporary device corresponding to the offset distance when landing is too large. The offset difference refers to the gap between the offset distance and the offset threshold, and the excess situation of the horizontal speed of the temporary device when landing is shown through the offset difference.

[0098] Step 221: Determine the horizontal throwing speed according to the offset difference and the transfer wind speed.

[0099] The horizontal throwing speed refers to the initial velocity value applied to the temporary device by the UAV when releasing the temporary device in the direction opposite to the transfer wind direction. The horizontal throwing speed can be obtained by querying from the horizontal throwing data table, which refers to the table recording the horizontal throwing speeds corresponding to different offset differences and transfer wind speeds.

[0100] Step 222: Determine the horizontal throwing position according to the offset threshold, transfer wind direction, and hovering position.

[0101] The horizontal throw position refers to the position point where the UAV needs to release the temporary device so that the temporary device falls at the hovering position after applying a horizontal throw speed to the temporary device. The horizontal throw position is the position point reached after moving the offset threshold in the direction opposite to the transfer 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.

[0102] Step 223: Control the preset UAV to move to the horizontal throw position and control the preset UAV to turn according to the transfer wind direction.

[0103] First, control the UAV to reach the horizontal throw position, and then control the UAV to face the direction opposite to the transfer wind direction, where the orientation of the UAV refers to the direction in which the UAV releases the temporary device.

[0104] Step 224: Control the preset UAV to eject the preset temporary device according to the horizontal throw speed.

[0105] When the wind speed is too high, the temporary device released from the UAV is easily affected by the wind speed, resulting in a large horizontal speed when the temporary device lands, and further leading to a large distance deviation between the stopping point of the temporary device and the expected location. At this time, an initial speed opposite to the wind direction is given to the temporary device to reduce the speed when the temporary device lands and improve the stability of the use of the temporary device.

[0106] Refer to Figure 7 , a data processing method in a wireless communication system, including: Step 300: Obtain the falling body speed based on the temporary device.

[0107] The falling body speed refers to the speed value at which the temporary device falls. The falling body speed can be obtained through a speed sensor in the temporary device. The method for obtaining the falling body speed is selected by the staff according to the actual situation and will not be elaborated here.

[0108] Step 301: When the falling body speed is higher than the preset impact resistance threshold, judge whether there is vegetation at the hovering position according to the geographical information.

[0109] The impact resistance threshold refers to the speed value corresponding to the maximum impact force that the temporary device can withstand. The impact resistance threshold is selected by the staff according to the actual situation and will not be elaborated here. When the falling body speed is higher than the impact resistance threshold, it means that the speed of the temporary device is too high at this time, which is likely to cause too large an impact force when the temporary device touches the ground, resulting in damage to the temporary device. The vegetation coverage information of the hovering position can be extracted from the geographical information to judge whether there is vegetation at the hovering position. The method for judging vegetation is common knowledge for those skilled in the art and will not be elaborated here.

[0110] Step 302: When there is vegetation at the hovering position, determine the vegetation type according to the geographical information and the hovering position.

[0111] The presence of vegetation at the hovering position indicates 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 types of vegetation at the hovering position, such as forests, shrubs, grasslands, etc. The vegetation type can be read from the vegetation coverage information in the geographical information. The method for determining the vegetation type is common knowledge for those skilled in the art and will not be elaborated here.

[0112] Step 303: Determine the vegetation height according to the vegetation type and obtain the falling time based on the temporary device.

[0113] The vegetation height refers to the height value of the vegetation at the hovering position. The vegetation height can be obtained by querying the vegetation data table, which refers to the data table recording different vegetation types and their corresponding vegetation heights.

[0114] The falling time refers to the duration elapsed after the temporary device is released from the drone. The falling time can be obtained through the timer in the temporary device. The method for obtaining the falling time is selected by the staff according to the actual situation and will not be elaborated here.

[0115] Step 304: Determine the falling height according to the falling time and the falling speed.

[0116] The falling height refers to the height value where the temporary device is located. The falling height can be calculated and determined by the falling time and the falling speed. The calculation method of the falling height is common knowledge for those skilled in the art and will not be elaborated here.

[0117] Step 305: When the falling height is consistent with the vegetation height, control the preset temporary device to deploy the preset buffer device.

[0118] The consistency between the falling height and the vegetation height indicates that the temporary device comes into contact with the vegetation. When the temporary device is released from the drone, it is easily affected by gravity and wind speed, resulting in a continuous increase in the falling speed of the temporary device. When the falling speed of the temporary device is too large, it is likely to cause the temporary device to be damaged due to a large impact force when it lands. At this time, check whether there is vegetation at the landing point of the temporary device, so as to control the buffer device to extend the metal strip when the temporary device contacts the vegetation, thereby increasing the contact area between the temporary device and the vegetation, reducing the impact force received by the temporary device, and improving the stability of the temporary device during use.

[0119] Refer to Figure 8 , a data processing method in a wireless communication system, further includes: Step 306: When there is vegetation at the hovering position, calculate the difference between the falling height and the vegetation height and define it as the height difference.

[0120] The height difference refers to the difference between the height of the temporary device and the vegetation height when the falling body speed is equal to the impact resistance threshold, and the distance between the temporary device and the vegetation when the falling body speed is equal to the impact resistance threshold is shown through the height difference.

[0121] Step 307: Determine the contact speed according to the height difference and the falling body speed.

[0122] The contact speed refers to the speed value when the temporary device contacts the vegetation. The contact speed can be queried and determined from the contact data table, and the contact data table refers to the data table that records different height differences and falling body speeds.

[0123] Step 308: Determine the buffer threshold according to the vegetation type.

[0124] The buffer threshold refers to the maximum speed value that the vegetation can effectively buffer. The buffer threshold can be obtained by querying from the threshold data table, and the threshold data table refers to the data table that records different vegetation types and their corresponding buffer thresholds.

[0125] Step 309: When the contact speed is higher than the buffer threshold, calculate the difference between the contact speed and the buffer threshold, and define it as the speed difference.

[0126] The contact speed being higher than the buffer threshold means that the speed of the temporary device when it contacts the vegetation is too high. At this time, it is difficult for the vegetation to quickly reduce the speed of the temporary device only. The speed difference refers to the difference between the contact speed and the buffer threshold, and the excess situation of the speed of the temporary device is shown through the speed difference.

[0127] Step 310: Determine the extension length according to the speed difference.

[0128] The extension length refers to the length value of the buffer device extending out of the metal strip. The extension length can be queried and determined from the extension data table, and the extension length data table refers to the data table that records different speed differences and their corresponding extension lengths.

[0129] Step 311: When the falling height is the same as the vegetation height, deploy the preset buffer device according to the extension length of the temporary device.

[0130] Different vegetation has different buffering capabilities for the temporary device. When the speed of the temporary device is too high and the buffering ability of the vegetation for the temporary device is weak, it is easy to cause the temporary device to still have a relatively high speed after being buffered by the vegetation. At this time, estimate the speed when the temporary device contacts the vegetation, and appropriately adjust the extension length of the buffer device according to the comparison relationship between the speed of the temporary device and the buffering ability of the vegetation, thereby increasing the contact area between the buffer device and the vegetation, improving the buffering ability of the buffer device, and enhancing the stability of the use of the temporary device.
