[0064] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0065] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0066] Figure 1 A flow chart of a method for link safety management of an unmanned aerial vehicle according to the present invention is shown.

[0067] like Figure 1 As shown, the present invention discloses a method for link safety management of an unmanned aerial vehicle, comprising:

[0068] S101, obtaining data information transmitted by an unmanned aerial vehicle;

[0069] S102, identifying the data transmitted by the unmanned aerial vehicle based on a preset verification token, and obtaining a verification token identification of the data transmitted by the unmanned aerial vehicle;

[0070] S103, determining whether the verification token identifier of the data transmitted by the unmanned aerial vehicle is consistent with the preset verification token of the corresponding unmanned aerial vehicle in the link node cloud. If so, the link node cloud allows data transmission, otherwise, it does not allow it.

[0071] According to an example of the present invention, a user can generate a verification token corresponding to an unmanned aerial vehicle through the identification information such as the number of the unmanned aerial vehicle, and bind the identification information such as the number of the unmanned aerial vehicle to the verification token; by presetting the verification token at each node of the link, and marking the transmitted data based on the verification token, interference from unmarked transmitted data is rejected, thereby ensuring the legitimacy of data transmission. An additional verification token corresponding to the unmanned aerial vehicle can be set as a backup verification token. The verification token and the backup verification token have the same security level and authority level, but different encryption algorithms can be used; when the above verification fails, the backup verification token is enabled for re-verification. The status of the verification information during the data transmission process in the link is monitored, so as to make a judgment on whether the data transmission is passed, thereby improving the safety and stability of the unmanned aerial vehicle. The link node cloud is composed of multiple link nodes.

[0072] According to an embodiment of the present invention, it also includes:

[0073] Obtain the serial number information of the unmanned aerial vehicle;

[0074] Matching the serial number information of the unmanned aerial vehicle with the preset verification token to obtain the verification token corresponding to the unmanned aerial vehicle;

[0075] Sending the verification token of the unmanned aerial vehicle to all link nodes corresponding to the unmanned aerial vehicle and a preset data processing terminal for storage;

[0076] The preset data processing terminal verifies the data transmitted by the unmanned aerial vehicle with a token.

[0077] It should be noted that the number information of the unmanned aerial vehicle can be its unique identifier, such as a one-dimensional code, a two-dimensional code, etc. By matching the number information with the verification token, it can be ensured that only the corresponding unmanned aerial vehicle can receive the transmitted data, thereby ensuring the security and legitimacy of the data. At the same time, the verification token is sent to all link nodes and the preset data processing end for storage, so that real-time monitoring and management of the data transmitted by the unmanned aerial vehicle can be achieved.

[0078] According to an embodiment of the present invention, it also includes:

[0079] Obtain information on the number of verification times during data transmission in the link;

[0080] Determine whether the number of verification times of the data transmission process in the link is greater than a preset first threshold, and if so, extract the link node with the largest number of verification times;

[0081] The link node with the most verification times is set as an unstable link node;

[0082] The location information of the unstable link node is extracted, and the location information of the unstable link node is sent to a preset management terminal for key monitoring.

[0083] It should be noted that the information on the number of verification times during the transmission process in the link can be obtained by monitoring the transmission time of the data in the link. When the number of verification times for data transmission in the link is greater than the preset first threshold, it can be considered that the link has certain risks and needs further processing. By extracting the link nodes with the most verification times, the nodes that may have problems can be determined and marked as unstable link nodes. At the same time, the location information of the unstable link nodes is sent to the preset management terminal for key monitoring, which can help to timely discover and solve problems in the link and improve the safety and stability of the unmanned aerial vehicle. In addition, while the unmanned aerial vehicle is matched with the preset verification token, its communication protocol, transmission data format and other information can be verified to ensure that the data transmitted by the unmanned aerial vehicle is legal and complete. At the same time, a corresponding alarm mechanism can be established to monitor and alarm abnormal situations such as communication protocols and transmission data formats, and problems can be discovered and handled in a timely manner.

[0084] According to an embodiment of the present invention, it also includes:

[0085] Get the time for data verification during transmission at each node of the link;

[0086] According to the time of data verification during the transmission process of each node in the link, the interval time of verification of adjacent link nodes is obtained;

[0087] Determine whether the interval time for the adjacent link nodes to perform verification is greater than a preset second threshold, and if so, trigger link node replacement prompt information;

[0088] Replace the next node in the adjacent link node.

[0089] It should be noted that, in the embodiment of the present invention, the time for obtaining data to be verified during the transmission process of each node in the link refers to the time from when the data is sent to the first node in the link to when the data is verified by all nodes in the link and returned to the unmanned aerial vehicle. By obtaining the interval time for adjacent link nodes to perform verification, it is possible to determine whether the nodes in the link are verified according to the prescribed time, thereby promptly discovering problems in the link. If the interval time for adjacent link nodes to perform verification is greater than a preset second threshold, a link node replacement prompt message can be triggered to replace the subsequent node in the link. The preset second threshold is set by a person skilled in the art.

[0090] According to an embodiment of the present invention, it also includes:

[0091] According to the time for verifying the data during the transmission process of each node in the link, the duration for the link to complete a data interaction is obtained;

[0092] Determine whether the duration of the link to complete a data interaction is greater than a preset third threshold, and if so, trigger link replacement prompt information;

[0093] The link replacement prompt information is sent to a preset management terminal for corresponding processing.

[0094] It should be noted that the duration of a link to complete a data interaction refers to the time from when the data is sent to the first node in the link to when the data is verified by all nodes in the link and returned to the unmanned aerial vehicle. By obtaining the duration of a link to complete a data interaction, the efficiency and stability of the data interaction in the link can be judged, and problems in the link can be discovered in time. For example, the preset third threshold is set to 10 minutes. If the duration of a link to complete a data interaction is greater than 10 minutes, the link replacement prompt information can be triggered, and the subsequent nodes in the link can be replaced to ensure the stability and security of the link. At the same time, the link replacement prompt information can be sent to the preset management terminal for corresponding processing.

[0095] According to an embodiment of the present invention, it also includes:

[0096] Acquire the data transmission interruption link node information in the link node;

[0097] Based on the preset standby link node, the data transmission interruption link node is replaced to obtain a revised link node cloud;

[0098] Send the UAV transmission data to the revised link node cloud for retransmission and verification.

[0099] It should be noted that obtaining the link node information of data transmission interruption in the link node means that in the process of link monitoring, by analyzing the data transmission situation in the link, it is found that there are interrupted or abnormal data transmission nodes. Based on the preset link nodes, these interrupted or abnormal data transmission nodes are replaced to obtain the revised link node cloud. In this way, all nodes in the link can be ensured to be in a normal state, thereby improving the safety and stability of the unmanned aerial vehicle.

[0100] According to an embodiment of the present invention, it also includes:

[0101] Obtaining a value of the number of replacement link nodes in the revised link node cloud;

[0102] Determine whether the revised link node value is greater than a preset fourth threshold, and if so, trigger a prompt message for changing the transmission link;

[0103] The transmission link change prompt information is sent to the preset management terminal for corresponding processing.

[0104] It should be noted that obtaining the numerical value of the number of replaced link nodes in the revised link node cloud means that after monitoring and analyzing the revised link node cloud, the number of replaced link nodes is counted. By judging whether the numerical value of the revised link nodes is greater than the preset fourth threshold, it can be judged whether the stability and security in the link meet the requirements. If the number of revised link nodes is greater than the preset fourth threshold, the prompt information for replacing the transmission link can be triggered, and the relevant personnel can be notified to handle it. The prompt information for replacing the transmission link is sent to the preset management terminal for corresponding processing, so that problems in the link can be discovered in time, and corresponding measures can be taken to deal with them. At the same time, the prompt information can be comprehensively analyzed together with other monitoring data. The preset fourth threshold is set by skilled technicians.

[0105] According to an embodiment of the present invention, it also includes:

[0106] Obtain environmental information and task information;

[0107] According to the environmental information and mission information, the theoretical flight position coordinates of the unmanned aerial vehicle are obtained;

[0108] Obtain the real-time position coordinates of the unmanned aerial vehicle;

[0109] Compare the real-time position coordinates of the unmanned aerial vehicle with the theoretical flight position coordinates to obtain a deviation value;

[0110] Determine whether the deviation value exceeds a preset fifth threshold, and if so, trigger a link position adjustment prompt message;

[0111] Based on the preset link adjustment scheme, the link position is adjusted accordingly.

[0112] It should be noted that unmanned aerial vehicles need to obtain environmental information and mission information when performing missions, which can be obtained through a variety of sensor devices, such as radar, camera, GPS, etc. The environmental information and mission information obtained by these sensor devices can be used to determine the theoretical flight position coordinates of the unmanned aerial vehicle. The theoretical flight position coordinates are the position coordinates where the unmanned aerial vehicle should fly under ideal circumstances. It can be determined by comprehensively considering a variety of factors, such as mission requirements, target location, weather conditions, terrain, etc.

[0113] After obtaining the real-time position coordinates of the unmanned aerial vehicle, it is necessary to compare them with the theoretical flight position coordinates to obtain the deviation value, that is, the difference between the actual flight position and the theoretical flight position. If the deviation value exceeds the preset fifth threshold, the link position adjustment prompt information can be triggered to notify relevant personnel to handle it. Link position adjustment refers to adjusting the link position of the unmanned aerial vehicle to ensure its flight safety and stability. Link position adjustment needs to be specifically designed and implemented according to actual conditions, and various factors need to be considered, such as link stability, security, communication quality, etc. Therefore, in practical applications, it is necessary to comprehensively consider various factors and take appropriate measures to ensure the flight safety and reliability of unmanned aerial vehicles. It should be noted that the unmanned aerial vehicle may be affected by various interference factors during the execution of its mission, such as signal interference, sudden weather changes, system failures, etc. Therefore, in practical applications, it is necessary to effectively monitor and manage unmanned aerial vehicles, and promptly discover and solve potential problems to ensure their stable and reliable operation.

[0114] According to an embodiment of the present invention, it also includes:

[0115] Get the number of times the link nodes are replaced at the same location;

[0116] Determine whether the number of times the link node is replaced at the same position exceeds a preset sixth threshold value, and if so, mark the position as a signal unstable area, triggering a link position adjustment prompt message;

[0117] The link position adjustment prompt information is sent to a preset management terminal for corresponding processing.

[0118] It should be noted that during the flight of the unmanned aerial vehicle, by monitoring the number of link node replacements, the stability of the link and the communication quality can be judged, and the position coordinates of the unmanned aerial vehicle can be determined. If the number of link node replacements at the same location exceeds the preset sixth threshold, the location will be marked as a signal unstable area, and a link position adjustment prompt message will be triggered to notify relevant personnel to handle it.

[0119] According to an embodiment of the present invention, it also includes:

[0120] Obtain historical transmission record information of unmanned aerial vehicles;

[0121] According to the historical transmission record information of the unmanned aerial vehicle, the accuracy value of the transmission data of each link node is obtained;

[0122] Determine whether the accuracy value of the data transmitted by the link node is greater than a preset seventh threshold; if not, replace the link node.

[0123] It should be noted that the historical transmission record information of the unmanned aerial vehicle includes all data transmission records of the unmanned aerial vehicle in the past period of time, such as sensor data, control instructions, etc. The historical transmission record information is analyzed, including statistics and analysis of the transmission data of each link node to determine the accuracy value of the link node transmission data. This process can be performed by using some data analysis tools and technologies, such as data mining, machine learning, etc.

[0140] The location information of the unstable link node is extracted, and the location information of the unstable link node is sent to a preset management terminal for key monitoring.

[0141] It should be noted that the information on the number of verification times during the transmission process in the link can be obtained by monitoring the transmission time of the data in the link. When the number of verification times for data transmission in the link is greater than the preset first threshold, it can be considered that the link has certain risks and needs further processing.

[0170] It should be noted that unmanned aerial vehicles need to obtain environmental information and mission information when performing missions, which can be obtained through a variety of sensor devices, such as radar, camera, GPS, etc. The environmental information and mission information obtained by these sensor devices can be used to determine the theoretical flight position coordinates of the unmanned aerial vehicle. The theoretical flight position coordinates are the position coordinates where the unmanned aerial vehicle should fly under ideal circumstances. It can be determined by comprehensively considering a variety of factors, such as mission requirements, target location, weather conditions, terrain, etc.

[0171] After obtaining the real-time position coordinates of the unmanned aerial vehicle, it is necessary to compare them with the theoretical flight position coordinates to obtain the deviation value, that is, the difference between the actual flight position and the theoretical flight position. If the deviation value exceeds the preset fifth threshold, the link position adjustment prompt information can be triggered to notify relevant personnel to handle it. Link position adjustment refers to adjusting the link position of the unmanned aerial vehicle to ensure its flight safety and stability. Link position adjustment needs to be specifically designed and implemented according to actual conditions, and various factors need to be considered, such as link stability, security, communication quality, etc. Therefore, in practical applications, it is necessary to comprehensively consider various factors and take appropriate measures to ensure the flight safety and reliability of unmanned aerial vehicles. It should be noted that the unmanned aerial vehicle may be affected by various interference factors during the execution of its mission, such as signal interference, sudden weather changes, system failures, etc. Therefore, in practical applications, it is necessary to effectively monitor and manage unmanned aerial vehicles, and promptly discover and solve potential problems to ensure their stable and reliable operation.

[0172] According to an embodiment of the present invention, it also includes:

[0173] Get the number of times the link nodes are replaced at the same location;

[0174] Determine whether the number of times the link node is replaced at the same position exceeds a preset sixth threshold value, and if so, mark the position as a signal unstable area, triggering a link position adjustment prompt message;

[0175] The link position adjustment prompt information is sent to a preset management terminal for corresponding processing.

[0176] It should be noted that during the flight of the unmanned aerial vehicle, by monitoring the number of link node replacements, the stability of the link and the communication quality can be judged, and the position coordinates of the unmanned aerial vehicle can be determined. If the number of link node replacements at the same location exceeds the preset sixth threshold, the location will be marked as a signal unstable area, and a link position adjustment prompt message will be triggered to notify relevant personnel to handle it.

[0177] According to an embodiment of the present invention, it also includes:

[0178] Obtain historical transmission record information of unmanned aerial vehicles;

[0179] According to the historical transmission record information of the unmanned aerial vehicle, the accuracy value of the transmission data of each link node is obtained;

[0180] Determine whether the accuracy value of the data transmitted by the link node is greater than a preset seventh threshold; if not, replace the link node.

[0181] It should be noted that the historical transmission record information of the unmanned aerial vehicle includes all data transmission records of the unmanned aerial vehicle in the past period of time, such as sensor data, control instructions, etc. The historical transmission record information is analyzed, including statistics and analysis of the transmission data of each link node to determine the accuracy value of the link node transmission data. This process can be performed by using some data analysis tools and technologies, such as data mining, machine learning, etc.
