[0002] In the integrated air-ground network, UAV (unmanned aerial vehicle) is widely used in rescue, inspection and other scenarios. However, in complex geographical environments, the obstruction of buildings, trees, hills and other terrains will shield the communication signals. At the same time, the signals of other wireless devices will also interfere with the communication of UAVs, resulting in interruption of UAV communication and loss of connection.

[0071] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0072] In an exemplary embodiment, Figure 1 As shown, a UAV communication method is provided, which is applied to a first UAV, and the UAV communication method includes the following steps 102 to 104. Among them:

[0073] Step 102, when the communication is interrupted, the UAV operation mode is switched to the first target operation mode, and a distress message is sent in the first target operation mode.

[0074] The distress message is forwarded to the drone central control platform through the second drone, which is used to instruct the drone central control platform to issue a rescue mission to the second drone.

[0075] In practice, in the integrated air-ground-space network, drones are widely used in various scenarios. However, the global surge in frequency-using devices and the increasingly complex electromagnetic environment have caused frequent interference to the communication of drones. Therefore, in order to ensure the safety of drones, an operation mode module is added to the drone, which contains a variety of drone operation modes, so that the drone can be flexibly switched based on scene changes during operation. Taking the first drone as an example, in order to ensure the communication security of the first drone, if the communication signal of the first drone is interfered with during the execution of the mission, and the communication with the drone central control platform is interrupted, the first drone switches the drone operation mode to the first target operation mode. In the first target operation mode (for example, the distress mode), the first drone broadcasts a distress message. The distress message can be received by drones near the first drone and forwarded to the drone central control platform.

[0076] Optionally, if the second UAV is near the location of the first UAV and is in good operating condition, and the second UAV receives a distress message broadcast by the first UAV, the second UAV will forward the distress message to the UAV central control platform, which will determine the accuracy of the distress message and, after verification, issue a rescue mission to the second UAV or other UAVs to carry out rescue of the first UAV.

[0077] Optionally, the distress message sent by the first drone includes but is not limited to the identity of the first drone (for example, ID (Identification)), location, power level, task importance level of the first drone's own task to be performed, etc., and the present disclosed embodiment does not limit this.

[0078] Step 104: receiving rescue information from the second drone based on the rescue information response, and establishing a communication connection with the second drone based on the rescue information.

[0079] Among them, the second drone is used for communication signal recovery.

[0080] In implementation, after the second drone receives the distress message from the first drone, the second drone forwards the distress message to the drone central control platform, and the drone central control platform verifies and judges the distress message. The drone central control platform issues a rescue mission after the verification is passed. If the drone central control platform assigns the second drone to perform the rescue mission, the second drone sends a rescue message to the first drone to respond to the distress message. The first drone receives the rescue message, which contains the attribute information and operating status of the second drone, such as the second drone ID, location, power, etc. The first drone verifies the rescue message to ensure the reliability of the communication between the two parties. When the rescue message verification is passed, the first drone establishes a communication connection with the second drone, and the second drone carries out the rescue mission.

[0081] Specifically, there are many ways for the second drone to rescue the first drone. For example, the second drone can evaluate the task importance level, task time limit, power of the first drone, operating status of the first drone and other information of the task to be executed corresponding to the first drone. If the task to be executed corresponding to the first drone is very important (i.e., the task importance level is high), and it is confirmed that the current operating status of the first drone cannot continue to execute the task, the second drone backs up the task data in the first drone through the communication connection with the first drone, and replaces the first drone to execute the task to ensure the task continuity of the task to be executed. In addition, the second drone can also publish information such as the current location and operating status of the first drone to the drone central control platform, and the drone central control platform instructs personnel to rescue the first drone. Alternatively, if the task time limit of the task to be executed corresponding to the first drone is very long, that is, it indicates that the task to be executed can be postponed, and the current operating status of the first drone is good, the second drone can wait for the first drone to resume communication while establishing communication with the first drone, or the second drone forwards the current situation to the drone central control platform, and after the instruction of the drone central control platform, temporarily cancels the task to be executed by the first drone and informs the first drone to return.

[0082] Optionally, there are multiple ways to rescue the first drone. The embodiments of the present disclosure cite the above-mentioned rescue methods as examples for explanation, but the embodiments of the present disclosure do not limit the rescue method of rescuing the first drone by the second drone.

[0083] In the above-mentioned drone communication method, a drone operation mode is added. When the communication of the first drone is interrupted, the first drone is switched to the first target operation mode so that the first drone can send a distress message, which is forwarded to the drone central control platform by the second drone. The drone central control platform issues a rescue mission to the second drone, so that the second drone can rescue the first drone. The first drone establishes a communication connection with the second drone to ensure data transmission between the first drone and the second drone, realize signal recovery, avoid leakage of important information, and ensure the mission continuity of the first drone.

[0084] In an exemplary embodiment, Figure 2 As shown, step 102 includes steps 202 to 204 .

[0085] in:

[0086] Step 202: When the communication is interrupted, the current UAV operation mode is switched to a distress mode.

[0087] In implementation, an operation mode module is added to the first drone, and the operation mode module includes multiple operation modes of the drone, such as normal mode, rescue mode and distress mode. When the first drone maintains communication with the drone central control platform, the first drone operates in normal mode. When the communication of the first drone is interrupted, the first drone actively switches the current drone operation mode from normal mode to distress mode.

[0088] Step 204, based on the preset power threshold and the current remaining power of the first drone, determine the information sending frequency, and send the distress message based on the information sending frequency in the distress mode.

[0089] In implementation, a power threshold is preset in the first drone, and the power threshold is used to determine the frequency of sending distress information of the first drone when asking for help. Specifically, in the distress mode, the first drone compares the preset power threshold with the current remaining power of the first drone, thereby determining the frequency of sending information, and sends the distress information in the distress mode based on the information sending frequency. If the current remaining power of the first drone is less than the preset power threshold, the first drone broadcasts the distress information according to the preset period in the distress mode; if the current remaining power of the first drone is greater than or equal to the preset power threshold, the first drone broadcasts the distress information in real time and continuously in the distress mode.

[0090] For example, if the current remaining power of the first drone is less than the preset power threshold, it indicates that the current remaining power of the first drone is insufficient, so the information transmission frequency is sent according to the preset period. For example, if the preset period is 15 minutes, the first drone broadcasts a distress message every 15 minutes in the distress mode. If the current remaining power of the first drone is greater than the preset power threshold, it indicates that the current remaining power of the first drone is sufficient, so the information transmission frequency can be real-time (extremely short time period) continuous transmission, for example, the first drone broadcasts a distress message every 1 second in the distress mode.

[0091] In this embodiment, the sending frequency of the distress message is dynamically adjusted by presetting the power threshold and real-time power monitoring, which can save energy while ensuring the efficiency of information transmission, avoid unnecessary waste of power, and extend the flight time of the first drone in an emergency.

[0092] In an exemplary embodiment, Figure 3 As shown, the specific processing process of step 104 includes:

[0093] Step 301: Receive rescue information from the second UAV based on the distress message response, and verify the rescue information.

[0094] In practice, when the first drone receives the rescue information replied by the second drone, in order to ensure the information security of the mission data in the first drone, the first drone needs to verify the rescue information. Optionally, the rescue information contains the attribute information and operation status information of the second drone, such as the ID, location, power, etc. of the second drone. The first drone has pre-stored verification rules and standards, so that the first drone can verify and identify the information of the second drone contained in the rescue information and verify the reliability of the second drone.

[0095] Step 302: When the rescue information verification is passed, a communication connection is established with the second UAV.

[0096] In the implementation, when the rescue information verification is passed, the first drone establishes a communication connection with the second drone. Specifically, when the rescue information verification is passed, a handshake is performed with the second drone using a preset communication protocol (such as LoRa, Wi-Fi, 4G / 5G, etc.). Necessary security keys and authentication information are exchanged to ensure encrypted and secure communication, dynamically adjust communication parameters (such as frequency, power, bandwidth, etc.) to adapt to environmental changes, and start redundant communication mechanisms (such as multi-point communication, backup frequency bands, etc.) to enhance the stability of the connection.

[0097] In this embodiment, the authenticity of the rescue information and the security of the communication are ensured through a strict verification and encryption mechanism. Through a stable communication connection, the second drone can quickly perform the task, shorten the response time, and ensure the efficient execution of the rescue mission.

[0098] In an exemplary embodiment, Figure 4 As shown, in addition to being rescued, the first drone can also participate in the rescue of other drones when the first drone is in normal operation. The method also includes:

[0099] Step 402: Receive the distress message sent by the third drone and verify the distress message.

[0100] In implementation, the first drone flies normally in normal mode. When passing near the third drone, it monitors the distress message of the third drone. The first drone receives the distress message sent by the third drone and verifies the distress message. The distress message includes the identity of the third drone (for example, ID (Identification), location, power, and the mission importance level of the third drone's own mission to be performed. The first drone can verify and identify the distress message based on the distress message to ensure the reliability of the distress message.

[0101] Step 404, when the distress message is verified, the distress message is forwarded to the drone central control platform, instructing the drone central control platform to issue a rescue mission.

[0102] In implementation, if the distress message passes verification, the first drone forwards the distress message to the drone central control platform, instructing the drone central control platform to issue a rescue mission. In this process, the first drone plays the role of monitoring and forwarding the distress message.

[0103] In this embodiment, the emergency information of the rescued third drone is monitored and forwarded through the common mode of the first drone, and there is no need to use a special search and rescue drone to carry out search and rescue, which saves drone resources and improves the efficiency of drone rescue.

[0104] In an exemplary embodiment, Figure 5 As shown, the method also includes:

[0105] Step 501, receiving a rescue mission issued by a drone central control platform, switching the drone operation mode to a second target operation mode, and moving to the position of a third drone in the second target operation mode.

[0106] In implementation, after receiving the distress message, the drone central control platform verifies the accuracy of the distress message and determines whether the first drone needs to interrupt its current pending task and execute the rescue of the third drone. If the drone central control platform identifies that the task importance level of the first drone's own pending task is low and / or the task validity period of the pending task is long, that is, the first drone can participate in the search and rescue of the third drone, then the drone central control platform can assign the first drone to search and rescue the third drone, that is, the drone central control platform issues a rescue task to the first drone. After the first drone receives the rescue task issued by the drone central control platform, it switches its own drone operation mode from the normal mode to the second target operation mode, that is, switches to the rescue mode, and goes to the location of the third drone for search and rescue in the rescue mode.

[0107] Optionally, if the drone central control platform identifies that the task importance level of the task to be performed by the first drone is high and / or the task validity period of the task to be performed is short, the first drone does not participate in the search and rescue of the third drone, and the drone central control platform can instruct other drones to participate in the rescue mission of the third drone.

[0108] Step 502: Send rescue information to the third drone, instructing to establish a communication connection with the third drone.

[0109] In practice, when the first drone performs a rescue, the first drone sends rescue information to the third drone, indicating that a communication connection is established with the third drone. This process is similar to the process of sending rescue information to the first drone when the second drone performs a rescue in step 104 above. Therefore, the detailed process of the third drone verifying the rescue information and establishing a communication connection with the first drone is not described in detail in the embodiment of the disclosure. In this way, after the first drone establishes a communication connection with the third drone, the first drone carries out the rescue mission.

[0110] In this embodiment, the first drone can quickly switch to the second target operation mode and immediately go to the designated location by quickly issuing the rescue mission through the drone central control platform, which greatly shortens the response time. The drone central control platform can automatically allocate rescue tasks according to real-time data and task priorities, improving the efficiency and accuracy of task processing. After the first drone arrives at the location of the third drone, it sends rescue information and establishes a communication connection, realizing direct communication and collaboration between drones, and enhancing the overall collaborative operation capability.

[0111] In an exemplary embodiment, Figure 6 As shown, a UAV communication method is provided, which is applied to a UAV central control platform. The UAV communication method includes the following steps 601 to 603.

[0112] in:

[0113] Step 601, receiving a distress message.

[0114] The distress message is obtained by switching the operation mode of the first drone to the first target operation mode and sending it to the second drone in the first target operation mode when the communication with the first drone is interrupted, and then forwarded by the second drone.

[0115] In the implementation, the first drone is used as the drone to be rescued, and the second drone is a drone near the first drone. For example, if the first drone's communication is interrupted, when broadcasting a distress message in the distress mode, the second drone passing near the first drone receives the distress message, and the second drone forwards the distress message to the drone central control platform. The drone central control platform is integrated with a task management module, which receives the distress message to further identify whether the first drone has lost communication, that is, the drone central control platform verifies the accuracy of the distress message. If the distress message passes the verification, the drone central control platform determines to conduct a search and rescue for the first drone.

[0116] The distress message includes the identity of the first drone (e.g., ID (Identification), location, power, mission importance level of the first drone's own mission to be performed, etc. The drone central control platform can verify the accuracy of the distress message based on the content contained in the distress message and the pre-examination verification rules, and determine whether the first drone is reliable, and formulate a corresponding rescue plan for the first drone if the verification passes.

[0117] Step 602, determining whether the second UAV meets the search and rescue conditions.

[0118] In implementation, the drone central control platform determines whether the second drone meets the search and rescue conditions, that is, the drone central control platform determines whether the second drone needs to interrupt the task currently being performed by the second drone and switch to search and rescue the first drone. Specifically, the second drone contains information such as its own remaining power, the task importance level of the task to be performed, etc. In this way, the drone central control platform makes a comprehensive judgment based on the information such as the second drone's own remaining power, the task importance level of the task to be performed, etc. and the preset search and rescue conditions to determine whether the second drone is needed for search and rescue.

[0119] Among them, satisfying the search and rescue conditions includes that the original task to be performed (or being performed) of the drone (the second drone in this embodiment) has a low task importance level, the task timeliness of the task to be performed is long, or the drone is not currently performing the task, etc. The disclosed embodiment does not limit the content of the search and rescue conditions.

[0120] Step 603: When the second UAV meets the search and rescue conditions, a search and rescue mission is issued to the second UAV, instructing the second UAV to respond to the rescue information of the first UAV.

[0121] During implementation, when the second UAV meets the search and rescue conditions, the UAV central control platform sends a search and rescue mission to the second UAV, instructing the second UAV to switch to search and rescue mode, arrive near the location of the first UAV to carry out search and rescue, and respond to the rescue information to the first UAV.

[0122] In this embodiment, the UAV central control platform can quickly initiate rescue operations and shorten response time by receiving the distress message forwarded by the second UAV and quickly determining whether the second UAV meets the search and rescue conditions. It uses a multi-layer communication mechanism to ensure effective transmission of information in a complex environment and reduce the risk of information loss. When the second UAV meets the search and rescue conditions, it quickly issues a search and rescue mission and responds to the rescue message to ensure that the first UAV can be rescued in time.

[0123] In an exemplary embodiment, Figure 7 As shown, the method also includes:

[0124] Step 702: When the second UAV does not meet the search and rescue conditions, a search and rescue mission is issued to the fourth UAV, instructing the fourth UAV to respond to the rescue message to the first UAV.

[0125] During implementation, when the second UAV does not meet the search and rescue conditions, the task management module of the UAV central control platform informs the second UAV to continue to execute the original pending task without search and rescue, and dispatches other UAVs, for example, the fourth UAV to perform search and rescue, that is, the UAV central control platform sends a search and rescue mission to the fourth UAV, instructing the fourth UAV to respond to the rescue message of the first UAV.

[0126] The process of the fourth drone responding to the rescue message and executing the rescue mission to the first drone is similar to the process of the second drone executing the rescue mission in step 104 in the above embodiment, and will not be repeated in detail in the embodiment of the present disclosure.

[0127] In this embodiment, when the second drone is unable to perform the rescue mission, the fourth drone is quickly dispatched to ensure that the rescue mission will not be interrupted due to the second drone not meeting the search and rescue conditions, thereby improving the flexibility and continuity of the rescue mission.

[0128] In an optional embodiment, in addition to passively receiving the forwarded distress message, the drone central control platform can also actively monitor and identify the interruption of the communication signal of the first drone. Specifically, the drone central control platform is integrated with a task management module, which is used to dispatch tasks to each drone and also monitor the communication status of each drone. When the drone central control platform monitors that the communication signal of the first drone is interrupted, the drone central control platform can also dispatch other drones to the first drone for search and rescue based on the location of the first drone, the task importance level of the task to be executed in the first drone, and other information. Figure 8 As shown, an example of a method for a UAV central control platform to actively search and rescue a first UAV is given, and the example specifically includes:

[0129] Step 801, UAV1 (the first UAV) communication is interrupted, and the operation mode module in the first UAV switches the execution state to the distress mode, and broadcasts distress information continuously or periodically according to the remaining power, waiting for rescue.

[0130] In step 802, the task management module of the drone central control platform detects that the communication of UAV1 is abnormally interrupted, and determines that UAV1 needs rescue based on the location of the first drone, the task importance level of the task to be performed in the first drone, and other information. At the same time, the drone central control platform determines that UAV2 (i.e., the second drone) performs the search and rescue mission of UAV1 based on the location, task importance level, and other information.

[0131] Step 803, the task management module of the UAV central control platform sends the rescue task of searching and rescuing UAV1 to the operation mode module of UAV2, and the rescue task includes the ID, location, mission importance level and other information of the first UAV.

[0132] From step 804 to step 805, UAV2 flies to the designated location, switches to the search and rescue mode, monitors the distress information of UAV1, broadcasts the rescue information, and applies to establish a communication connection with UAV1.

[0133] Step 806: UAV1 identifies the received rescue information and establishes a communication connection.

[0134] From step 807 to step 808, UAV1 sends its own ID, location, remaining power, mission execution status and other information, and UAV2 acts as a relay to forward the information to the UAV central control platform.

[0135] In an optional embodiment, if Fig. 9 As shown, an example of a method for a UAV central control platform to passively search and rescue a first UAV is given, and the example specifically includes:

[0136] Step 901, UAV1 (i.e., the first UAV) communication is interrupted, and the operation mode module in UAV1 switches from normal mode to distress mode, and broadcasts distress information continuously or periodically according to the remaining power, waiting for rescue.

[0137] Step 902, UAV1 broadcasts a distress message, which includes information such as ID, location, power, mission importance level, etc. The distress signal is continuously broadcast when the power level is higher than a preset power threshold, and the distress message is periodically broadcast when the power level is lower than a preset power threshold.

[0138] Step 903, UAV2 (i.e., the second UAV) operates in a normal mode when performing a mission, and detects a distress message from UAV1 when passing near UAV1.

[0139] Step 904, UAV2 forwards the distress message to the UAV central control platform.

[0140] Step 905, the task management module of the UAV central control platform receives the distress message, verifies the accuracy of the distress message, and determines whether UAV2 needs to interrupt the current mission to perform search and rescue.

[0141] From step 906a to step 908a, the task management module of the UAV central control platform sends a search and rescue task to UAV2, and UAV2 switches to the search and rescue mode and arrives at the designated location for search and rescue.

[0142] From step 906b to step 908b, the task management module of the UAV central control platform informs UAV2 to continue to perform the current task without search and rescue, and dispatches other UAVs to perform search and rescue.

[0143] Step 909: UAV1 identifies the received rescue information and establishes a connection with UAV2.
