[0052] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] The first embodiment of the present invention relates to a vehicle-mounted drone rescue method, see Figure 1, shows a flowchart of the steps of a vehicle-mounted drone rescue method provided by an embodiment of the present invention, which is applied to a vehicle side, the vehicle side is equipped with a drone, the vehicle communicates with the drone, and the vehicle-mounted drone rescue method includes the following steps:

[0054] Step 101, monitor that a vehicle enters an emergency rescue state, obtain the vehicle position information and state information, and generate a rescue data packet with the position information and state information.

[0055] In an embodiment of the present invention, in order to solve the problem that when a vehicle has an accident or the vehicle rescue system is damaged and the signal at the current location is poor, it is impossible to send out rescue information in time to seek help, which seriously affects the rescue efficiency, the vehicle side uses the configured drone, and the vehicle communicates with the drone. Through the high-altitude position advantage of the vehicle-mounted drone, the broadcast range of the distress message is effectively expanded, especially in remote areas without mobile phone signals, to ensure that the distress message can be transmitted to potential rescue ends, thereby improving the speed and efficiency of transmitting distress information in vehicle emergency situations and realizing effective and reliable drone rescue.

[0056] It should be noted that the vehicle side includes the vehicle host, vehicle drone, vehicle sensor, communication module and power supply. The vehicle host is the system control center and is responsible for communicating with drones, vehicle sensors and other equipment. The vehicle side is equipped with drones, which have flight, communication, image transmission and other functions. The vehicle sensors include GPS, gyroscopes, barometers, etc., which are used for positioning, attitude measurement, etc. The communication module uses a communication protocol stack to achieve communication between different devices, including communication between the vehicle computer and drones, and between drones and other devices. The power supply is used to power the entire system. The drone side includes flight control, communication module, etc. The flight control is used to control the flight attitude and route of the drone. The communication module supports communication with the vehicle host and other equipment. In addition, a camera can be configured to shoot the external environment and can be used for search and rescue. The sensors include GPS, gyroscopes, barometers, etc., which are used for positioning, attitude measurement, etc. The power supply is used to power the drone. I will not go into details here.

[0057] Specifically, when the vehicle detects that the vehicle has entered an emergency rescue state, it obtains the vehicle's location information and status information, and generates a distress data packet with the location information and status information. The distress data packet includes fields such as vehicle ID, timestamp, location information, and status information. When the vehicle detects that the vehicle has entered an emergency rescue state, it quickly prepares the distress data packet and waits for further rescue steps.

[0058] In this embodiment, the vehicle side can monitor whether the vehicle enters an emergency rescue state by active triggering or passive triggering. The emergency rescue state includes any emergency state in which the vehicle fails or is abnormal and requires rescue. In this embodiment, passive monitoring can be that the controller on the vehicle side monitors data through on-board sensors (such as collision detection, sudden changes in vehicle speed, airbag deployment, etc.) to detect whether the vehicle is in an emergency. Active triggering means that the vehicle user, that is, the driver or passenger, can actively press the emergency button on the on-board control panel to manually trigger the rescue function. After the on-board system confirms that an emergency situation has been detected, it automatically starts the rescue program and notifies the drone system to enter standby status.

[0059] It should be noted that after the vehicle controller detects that the vehicle has entered an emergency rescue state, it needs to check the status of each system to ensure that the GPS, communication module and battery are working properly, and prepare for the rescue operation. The vehicle controller can generate a brief overview of the emergency situation, such as emergency collision, abnormal position, etc., as part of the rescue information, which is not specifically limited here.

[0060] In an embodiment of the present invention, after the vehicle controller detects that the vehicle has entered an emergency rescue state, it first obtains the vehicle's location information and status information, wherein the location information includes GPS positioning and current time, and the status data includes the vehicle's driving data, such as vehicle speed, engine status, temperature, fuel level, battery power, etc. Specifically, the vehicle location information can obtain the vehicle's real-time location data through the on-board GPS module, including precise information such as longitude, latitude, altitude, speed and direction, and obtain the precise current time from GPS or Network Time Protocol (NTP), and record it as a distress timestamp. The vehicle status information is collected through sensor data, and the system collects various status data of the vehicle, integrates the location, time, vehicle status and emergency overview into a distress data packet, and performs data verification to ensure integrity and accuracy.

[0061] Step 102, encrypt the distress data packet using an agreed algorithm, and send the encrypted distress data packet to the drone; wherein the drone is used to broadcast distress in a preset area using the encrypted distress data packet and monitor the rescue information of the rescue end.

[0062] In an embodiment of the present invention, the vehicle end uses an agreed algorithm to encrypt a distress data packet and sends the encrypted distress data packet to a drone. The drone is used to broadcast distress in a preset area using the encrypted distress data packet and monitor the rescue information from the rescue end. It should be noted that the agreed algorithm includes an encryption algorithm and a decryption algorithm for the distress data packet agreed upon in advance by the vehicle end, the drone end, and the rescue end. This embodiment does not specifically limit the encryption algorithm and the decryption algorithm. A suitable encryption algorithm can be agreed upon and selected in advance, such as the symmetric encryption AES algorithm or the asymmetric encryption RSA algorithm, to ensure the security of the distress information during transmission. The rescue end is a device searched by the drone in a preset area, and can be another drone, a mobile phone, a tablet or other receiving device.

[0063] Specifically, the vehicle side uses an agreed algorithm to encrypt the distress data packet. The distress data packet can be encrypted using a key agreed upon in advance with the drone and the rescue side, or a secure encryption algorithm (such as AES, RSA, etc.) can be selected to ensure that the encrypted data packet is not easily cracked during transmission. The encrypted distress data packet is sent to the drone. The encrypted distress data packet can be sent to the drone through an on-board communication module (such as WIFI, Bluetooth, 4G / 5G, etc.) to ensure the transmission stability and reliability of the data packet.

[0064] Step 103, receiving the rescue information from the rescue end returned by the drone, and performing rescue using the rescue information.

[0065] In an embodiment of the present invention, the vehicle side receives the rescue information from the rescue side returned by the drone. The rescue information is the rescue side decrypting the distress data packet broadcast by the drone, determining the rescue strategy based on the vehicle's location information and status information, and performing rescue using the rescue strategy in the rescue information. The rescue information includes the rescue strategy, and the rescue strategy can be that the rescue side plans the optimal rescue path based on the location and status of the rescue vehicle, and navigates to the location of the rescue vehicle.

[0066] It should be noted that nearby devices continuously scan the set channels through Wi-Fi modules or private protocol modules to capture any broadcast distress messages. After receiving the distress data packet broadcast by the drone, the device immediately decrypts the distress data packet and extracts the original vehicle location information, time and vehicle status information after decryption. The rescue end that receives the distress message generates a confirmation callback rescue message based on the decrypted information. The rescue information also includes the location information and confirmation message of the rescue end. After receiving the confirmation message, the drone decrypts and verifies it to ensure that the response of the rescue end is legal. The on-board system receives the rescue information sent back by the drone, decrypts it and displays it on the on-board display screen to prompt the rescuer that the distress message has been successfully received.

[0067] The vehicle-mounted drone rescue method provided by the embodiment of the present invention monitors that the vehicle enters an emergency rescue state, obtains the vehicle position information and status information, generates a distress data packet from the position information and status information, encrypts the distress data packet using an agreed algorithm, and sends the encrypted distress data packet to the drone. The drone uses the encrypted distress data packet to broadcast distress in a preset area, and monitors the rescue information of the rescue end. The vehicle receives the rescue information of the rescue end returned by the drone, and uses the rescue information to perform rescue. The embodiment of the present invention effectively expands the broadcast range of the distress information through the high-altitude position advantage of the vehicle-mounted drone, especially in remote areas without mobile phone signals, ensuring that the distress information can be transmitted to potential rescue ends. From triggering the distress to the drone taking off and broadcasting, and then to the rescue end responding and feedback, the entire process is highly automated, which improves the speed and efficiency of the transmission of distress information in vehicle emergency situations, and the entire distress data transmission link is encrypted to ensure the security of the distress information during the transmission process, to achieve effective and reliable drone rescue, further improve driving safety, and meet user needs.

[0068] Further, see Figure 2 , showing Figure 1 The flowchart of step 101 of the vehicle-mounted drone rescue method provided is substantially the same as the vehicle-mounted drone rescue method provided in the first embodiment of the present invention. Step 101 includes:

[0069] Step 1011, monitoring vehicle driving data and user operations;

[0070] Step 1012, in response to abnormal driving data or a user triggering a help operation, determining that the vehicle enters an emergency help state.

[0071] Among them, the drone is activated when the vehicle enters an emergency rescue state.

[0072] Step 1013, obtaining the vehicle location information and status information, and generating a distress data packet based on the location information and status information according to the distress timestamp.

[0073] It should be noted that, in the embodiment of the present invention, the driving data and user operations of the vehicle are monitored in real time, and the driving data of the vehicle, including speed, direction, acceleration, turning angle, etc., are obtained through vehicle-mounted sensors (such as GPS, gyroscope, accelerometer, etc.), and whether the user presses the emergency rescue button or other rescue operations is monitored. According to the abnormal driving data or the user triggering the rescue operation, it is determined that the vehicle enters the emergency rescue state, and the drone is started when the vehicle enters the emergency rescue state. When the driving data (such as speed, acceleration, turning angle, etc.) exceeds the preset safety range, it is determined that the vehicle enters the emergency rescue state; when the user presses the emergency rescue button or other rescue operations, it is determined that the vehicle enters the emergency rescue state, the current position information and status information of the vehicle are obtained, and a rescue data packet is generated. The position information and status information, such as the latitude and longitude, altitude, etc. of the vehicle, the speed, direction, battery power, sensor status, etc. of the vehicle are obtained through the vehicle-mounted GPS module, and the timestamp of the vehicle entering the emergency rescue state is recorded, and the position information, status information and rescue timestamp are combined into a rescue data packet, and the rescue data packet contains fields such as vehicle ID, timestamp, position information, status information, etc.

[0074] The embodiment of the present invention timely generates valid information including vehicle status and vehicle location by monitoring the vehicle entering an emergency rescue state, and generates a distress data packet to start the drone rescue program. The entire process is highly automated, which improves the speed and efficiency of distress information transmission.

[0075] Further, see Figure 3 , showing Figure 1 The flowchart of step 102 of the vehicle-mounted drone rescue method provided is substantially the same as the vehicle-mounted drone rescue method provided in the first embodiment of the present invention. Step 102 includes:

[0076] Step 1021, agree in advance with the drone end and the rescue end on the encryption algorithm and decryption algorithm of the distress data packet.

[0077] Step 1022, encrypt the distress data packet using an encryption algorithm, and send the encrypted distress data packet to the drone. The drone is used to verify the distress data packet using the encryption algorithm, and the rescue end is used to decrypt the distress data packet broadcast by the drone using a decryption algorithm.

[0078] It should be noted that in the embodiment of the present invention, the vehicle side pre-agrees with the drone side and the rescue side on the encryption algorithm and decryption algorithm of the distress data packet. The encryption algorithm can select a secure encryption algorithm (such as AES, RSA, etc.), and the decryption algorithm selects a decryption algorithm corresponding to the encryption algorithm, and it is necessary to ensure the secure transmission and management of the encryption and decryption keys. The vehicle side uses the agreed algorithm to encrypt the distress data packet, and sends the encrypted distress data packet to the drone through the vehicle communication module (such as WIFI, Bluetooth, 4G / 5G, etc.). The drone is used to verify the distress data packet using the encryption algorithm. After the drone receives the encrypted distress data packet, it uses the agreed encryption algorithm to verify the data packet to ensure the integrity and authenticity of the data packet. After the rescue side receives the distress data packet broadcast by the drone, it uses the agreed decryption algorithm to decrypt the data packet to obtain the distress information.

[0079] The embodiment of the present invention uses an encryption algorithm to encrypt the distress data packet before sending it to the drone. The entire information transmission link is encrypted to ensure the security of the distress information during transmission, prevent the information from being stolen or tampered with, and at the same time ensure the trust chain between the person in distress and the rescuer, thereby achieving reliable drone rescue.

[0080] Further, see Figure 4 , showing Figure 1 The flowchart of step 103 of the vehicle-mounted drone rescue method provided is substantially the same as the vehicle-mounted drone rescue method provided in the first embodiment of the present invention. Step 103 includes:

[0081] Step 1031, receiving the rescue information from the rescue end returned by the drone; wherein the rescue information is the rescue end decrypting the distress data packet broadcast by the drone and determining the rescue strategy according to the vehicle location information and status information.

[0082] Step 1032, performing rescue using the rescue strategy in the rescue information.

[0083] It should be noted that, in an embodiment of the present invention, the vehicle side receives the rescue information from the rescue side returned by the drone, and performs rescue according to the rescue information. Specifically, the drone sends the received rescue information back to the vehicle side through the communication module. After receiving the rescue information, the vehicle side decrypts and parses the rescue information content. The rescue information is the rescue side decrypting the distress data packet broadcast by the drone, and determining the rescue strategy based on the vehicle's location information and status information. The on-board system receives the rescue information sent back by the drone, and displays it on the on-board display screen after decryption to prompt the rescuer that the distress information has been successfully received and the rescue is performed using the rescue strategy in the rescue information. The rescue information includes the rescue strategy. The rescue strategy can be that the rescue side plans the optimal rescue path based on the location and status of the rescue vehicle, and navigates to the location of the rescue vehicle.

[0084] In the embodiment of the present invention, the drone promptly monitors and returns the rescue information of the rescue end, providing a real-time feedback mechanism to ensure that the rescuer can know whether the rescue information has been received at the first time, and obtain the rescue information of the rescuer in time, thereby reducing the anxiety of the rescuer and realizing reliable drone rescue.

[0085] Reference Figure 5 , shows a flowchart of another vehicle-mounted drone rescue method provided by an embodiment of the present invention, which is applied to a drone end, the drone is configured on a vehicle, the drone communicates with the vehicle, and the method may include:

[0086] Step 201, receiving an encrypted distress data packet sent by the vehicle end; wherein the distress data packet is generated by the vehicle end when it detects that the vehicle has entered an emergency distress state, obtains the vehicle position information and status information, and uses the position information and status information.

[0087] In the embodiment of the present invention, the drone is configured in the vehicle, and the on-board controller establishes a stable communication link with the drone through Wi-Fi or a private protocol module. When the vehicle detects that the vehicle has entered an emergency rescue state, it obtains the vehicle's location information and status information, and uses the location information and status information to generate a distress data packet. The vehicle uses the agreed algorithm pre-determined with the drone to encrypt the distress data packet, and the vehicle sends the encrypted distress data packet to the drone through the communication link. The drone receives the encrypted distress data packet sent by the vehicle, confirms that the distress data packet is correct, stores the data in the memory, and prepares to enter the flight and broadcast state.

[0088] Step 202, using the encrypted distress data packet to broadcast distress in a preset area, and monitoring the rescue information from the rescue end.

[0089] In an embodiment of the present invention, the drone uses an encrypted distress data packet to broadcast distress in a preset area, wherein the preset area is an area where the drone takes off from the roof of a car and cruises at a preset flight altitude and path to ensure that the optimal broadcast range is achieved. In this embodiment, the drone can adjust its flight position in real time according to actual conditions, use GPS to ensure stable flight within the preset area, and optimize signal coverage.

[0090] Specifically, the drone scans the surrounding Wi-Fi channels or private protocol channels, selects a clean channel with minimal interference for broadcasting, automatically sets the broadcast channel, and prepares to send encrypted distress messages. The drone continuously broadcasts encrypted distress messages through the selected channel. During the broadcast process, the drone can repeatedly send distress packets to ensure that devices within the coverage area can receive the information. The drone continuously monitors the status of the broadcast signal to ensure stable output on the channel.

[0091] In this embodiment, the drone enters the monitoring mode after broadcasting and monitors the rescue information from the rescue end, that is, monitors the callback signal on the same channel. The drone is ready to receive and process any callback signal from the rescue end device and temporarily store it. If the rescue end device sends a callback message, the drone will immediately receive and record it. The drone will perform a preliminary confirmation of the callback signal to ensure that the signal is not damaged or interfered with. The drone will decrypt and verify the received rescue information and process it using the same encryption algorithm and key as the vehicle end. The verified rescue information will be stored and ready to be transmitted back to the vehicle end.

[0092] Step 203, returning the rescue information of the rescue end to the vehicle end; wherein the vehicle end is used to perform rescue using the rescue information.

[0093] In an embodiment of the present invention, the drone returns the rescue information of the rescue end to the vehicle end, and the vehicle end is used to perform rescue using the rescue information. Specifically, the rescue end, i.e., a nearby device, continuously scans the set channel through a Wi-Fi module or a private protocol module to capture any broadcasted distress information, generates rescue information after receiving the distress information broadcast by the drone, and can pop up an emergency alarm on the screen, showing in detail the location, status, time and other information of the rescuer, so as to formulate rescue strategies and respond to rescue in a timely manner. After receiving the rescue information, the drone decrypts and verifies it to ensure that the rescue end response is legal. The drone transmits the rescue information back to the vehicle end through a private protocol or Wi-Fi link. The vehicle end receives the feedback information sent back by the drone, decrypts it and presents it on the vehicle display screen, notifying the user that the distress information has been successfully received.

[0094] Specifically, after the rescue end confirms the start of the rescue operation, the device automatically generates rescue status update information and sends it to the drone through the channel. The drone then returns the rescue status update information to the vehicle end. After the rescue vehicle end receives the rescue status update information, it updates the status display to confirm that someone has gone to rescue.

[0095] The vehicle-mounted drone rescue method provided by the embodiment of the present invention is that the drone receives an encrypted distress packet sent by the vehicle end. The distress packet is generated by the vehicle end detecting that the vehicle enters an emergency distress state, obtaining the vehicle location information and status information, and using the location information and status information. The encrypted distress packet is used to broadcast distress in a preset area, and the rescue information of the rescue end is monitored, and the rescue information of the rescue end is returned to the vehicle end, and the vehicle end uses the rescue information to perform rescue. The embodiment of the present invention effectively expands the broadcast range of the distress information through the high-altitude position advantage of the vehicle-mounted drone, especially in remote areas without mobile phone signals, to ensure that the distress information can be transmitted to potential rescue ends. From triggering the distress to the drone taking off and broadcasting, and then to the rescue end responding and feedback, the entire process is highly automated, which improves the speed and efficiency of the transmission of distress information in vehicle emergency situations, and the entire distress data transmission link is encrypted to ensure the security of the distress information during the transmission process, to achieve effective and reliable drone rescue, further improve driving safety, and meet user needs.

[0096] Specifically, step 202 uses the encrypted distress data packet to broadcast distress in a preset area and monitors the rescue information of the rescue end, specifically including:

[0097] First, cruise using a preset flight altitude and flight path to determine the target broadcast channel;

[0098] Secondly, the encrypted distress data packet is broadcasted on the target broadcast channel;

[0099] Secondly, monitor the target broadcast channel to see if there is any rescue information returned by the rescue end within a preset time period; wherein, the rescue information is the information returned by the rescue end after receiving the encrypted distress data packet broadcast by the drone.

[0100] It should be noted that in the embodiment of the present invention, the drone is started when the vehicle enters the emergency rescue state, cruises using a preset flight altitude and flight path, rises to a predetermined altitude (such as 100 meters), and performs positioning and attitude measurement through built-in sensors (GPS, gyroscope, barometer, etc.), and first determines the target broadcast channel, receives the encrypted distress data packet, and broadcasts it on the target broadcast channel in the preset area through a communication module (such as WIFI, private protocol, etc.). The drone broadcasts the distress data packet and monitors the target broadcast channel for rescue information returned by the rescue end within a preset time period, wherein the rescue information is the information returned by the rescue end after receiving the encrypted distress data packet broadcast by the drone. If no rescue information is heard from the rescue end within the preset time period, a prompt message of rescue failure is returned to the vehicle end, so that the vehicle end can re-seek help or change the rescue method according to the prompt message, which is not specifically limited here.

[0101] The embodiments of the present invention utilize the high-altitude position advantage of the drone to broadcast the distress data packet on the target broadcast channel, effectively expanding the propagation range of the distress information, especially in remote areas without mobile phone signals, ensuring that the distress information can be transmitted to potential rescue ends, and improving the reliability of broadcasting the distress information.
