Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted emergency alarms, and in particular to a vehicle-mounted emergency alarm unmanned aerial vehicle system and method for highway accidents. Background Technology

[0002] Currently, after an accident on a highway, the primary method of handling accidents relies on drivers and passengers manually placing a warning triangle. This method has a fatal flaw:

[0003] 1. Extremely high safety risk: People need to walk 150 meters behind the vehicle in high-speed traffic, which greatly increases the risk of secondary injuries or fatalities;

[0004] 2. Long warning delay: It takes a long time from the time the accident occurs to the time it takes to locate and place warning signs, making it impossible to provide immediate warnings;

[0005] 3. Poor warning effect: The triangular warning sign is small in size and has limited visibility in bad weather, on curves or at night, resulting in low visibility.

[0006] 4. Low level of intelligence: It relies entirely on manual operation and cannot respond automatically.

[0007] Existing drone traffic monitoring solutions are mostly proactive patrols rather than emergency alarm systems that are deeply integrated with accident vehicles and automatically triggered. Therefore, a vehicle-mounted emergency alarm drone system and method for highway accidents are proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a vehicle-mounted emergency alarm drone system and method for highway accidents, which can achieve this.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] This invention discloses a vehicle-mounted emergency alarm drone system for highway accidents, comprising:

[0011] The vehicle-mounted triggering unit connects to the vehicle's safety sensors and is used to automatically generate a trigger signal when an accident is detected.

[0012] The drone cabin, integrated into the vehicle, is used to store and protect drones and features an automatically opening hatch.

[0013] The drone itself consists of a flight controller, a positioning module, obstacle avoidance sensors, a high-brightness warning light, and a high-decibel alarm.

[0014] The ground control center, located inside the vehicle, is used to receive the trigger signal and perform fully automated control of the unmanned cabin and the unmanned aircraft itself.

[0015] As a preferred embodiment of the present invention, the vehicle-mounted triggering unit is directly electrically connected to the vehicle's collision sensor or airbag controller and is equipped with a manual triggering interface.

[0016] As a preferred embodiment of the present invention, the positioning module of the UAV body is a GPS / BeiDou dual-mode positioning module, and the obstacle avoidance sensor is an obstacle avoidance system that integrates a forward-looking vision sensor and an ultrasonic sensor.

[0017] As a preferred embodiment of the present invention, the high-brightness warning light is an LED strobe light with a brightness of not less than 1000 lumens, and the high-decibel alarm is an electronic alarm with a volume of not less than 120 decibels.

[0018] As a preferred embodiment of the present invention, the ground control center is configured to: calculate the coordinates 150 meters behind the vehicle as the predetermined warning position based on the vehicle's real-time GPS coordinates using a dead reckoning algorithm, and plan the flight path of the UAV.

[0019] A vehicle-mounted emergency alarm method for highway accidents, employing the vehicle-mounted emergency alarm unmanned aerial vehicle system for highway accidents as described in any one of claims 1-5, and comprising the following steps:

[0020] Accident triggering steps: A vehicle accident is detected by the on-board triggering unit, and a triggering signal is generated;

[0021] System startup steps: The ground control center receives the trigger signal and controls the UAV cabin door to open;

[0022] Autonomous flight procedure: The drone takes off automatically from inside the cabin and flies to the predetermined warning position behind the accident vehicle according to the preset program;

[0023] Hovering alarm procedure: The drone hovers at the predetermined warning location and simultaneously activates the audible and visual alarm device to issue a warning;

[0024] Mission completion steps: Upon receiving a return-to-home command or meeting preset conditions, the drone will automatically return and land in the drone cabin.

[0025] As a preferred embodiment of the present invention, in the autonomous flight step, the UAV uses obstacle avoidance sensors to perceive the environment and avoid obstacles in real time during flight.

[0026] As a preferred embodiment of the present invention, in the hovering alarm step, the hovering height of the UAV is 5-15 meters, preferably 10 meters.

[0027] As a preferred technical solution of the present invention, the return command is issued by the user through a mobile terminal APP or remote controller, and the preset condition is that the drone's battery level is below a threshold or a remote command is received from the traffic management system.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention is fully automated, eliminating personal risks: it realizes a fully automated closed loop of "accident perception - drone deployment - warning", and personnel do not need to get out of the vehicle, fundamentally eliminating the risk of personal injury in secondary accidents.

[0030] This invention offers rapid response and achieves "zero-delay" early warning: from the occurrence of an accident to the drone taking off to issue an alarm, the entire process can be completed within tens of seconds, much faster than manual placement, providing valuable early warning time for vehicles behind.

[0031] This invention revolutionizes the warning effect: As an aerial mobile platform, the drone possesses advantages in altitude and maneuverability. Its high-brightness flashing light and high-decibel siren provide a warning effect far exceeding that of a static warning triangle.

[0032] This invention is highly intelligent and precise: the system automatically calculates warning positions that comply with regulations and ensures accurate positioning through precise hovering; obstacle avoidance function ensures flight safety; and deep integration with vehicles demonstrates the innovative application of intelligent connected vehicles in the field of safety.

[0033] This invention eliminates the life safety risks of manually setting up warning signs, achieves a rapid early warning response with "zero delay" after an accident, provides long-distance, high-intensity, and more conspicuous sound and light alarm signals, and realizes full automation and intelligence in the early warning process.

[0039] Example 1

[0040] like Figure 1-2 As shown, the present invention provides a vehicle-mounted emergency alarm drone system for highway accidents, comprising:

[0041] The vehicle-mounted triggering unit connects to the vehicle's safety sensors and is used to automatically generate a trigger signal when an accident is detected.

[0042] The drone cabin, integrated into the vehicle, is used to store and protect drones and features an automatically opening hatch.

[0043] The drone itself consists of a flight controller, a positioning module, obstacle avoidance sensors, a high-brightness warning light, and a high-decibel alarm.

[0044] The ground control center, located inside the vehicle, is used to receive the trigger signal and perform fully automated control of the unmanned cabin and the unmanned aircraft itself.

[0045] The vehicle-mounted triggering unit is directly electrically connected to the vehicle's collision sensors or airbag controller and is equipped with a manual triggering interface.

[0046] The positioning module of the UAV body is a GPS / BeiDou dual-mode positioning module, and the obstacle avoidance sensor is an obstacle avoidance system that integrates a forward-looking vision sensor and an ultrasonic sensor.

[0047] The high-brightness warning light is an LED strobe light with a brightness of not less than 1000 lumens, and the high-decibel alarm is an electronic alarm with a volume of not less than 120 decibels.

[0048] The ground control center is configured to: calculate the coordinates 150 meters behind the vehicle as the predetermined warning position based on the vehicle's real-time GPS coordinates using a dead reckoning algorithm, and plan the flight path of the UAV.

[0049] A vehicle-mounted emergency alarm method for highway accidents, employing the vehicle-mounted emergency alarm unmanned aerial vehicle system for highway accidents as described in any one of claims 1-5, and comprising the following steps:

[0050] Accident triggering steps: A vehicle accident is detected by the on-board triggering unit, and a triggering signal is generated;

[0051] System startup steps: The ground control center receives the trigger signal and controls the UAV cabin door to open;

[0052] Autonomous flight procedure: The drone takes off automatically from inside the cabin and flies to the predetermined warning position behind the accident vehicle according to the preset program;

[0053] Hovering alarm procedure: The drone hovers at the predetermined warning location and simultaneously activates the audible and visual alarm device to issue a warning;

[0054] Mission completion steps: Upon receiving a return-to-home command or meeting preset conditions, the drone will automatically return and land in the drone cabin.

[0055] During the autonomous flight phase, the UAV uses obstacle avoidance sensors to perceive the environment and avoid obstacles in real time during flight.

[0056] In the hovering alarm step, the hovering height of the drone is 5-15 meters, preferably 10 meters.

[0057] The return-to-home command is issued by the user via a mobile terminal APP or remote control. The preset conditions are that the drone's battery level is below a threshold or that a remote command is received from the traffic management system.

[0058] The operation process of this invention is as follows:

[0059] When a vehicle collision occurs or a user manually presses the alarm button, the onboard trigger unit immediately sends a trigger signal to the ground control center. The signal contains information such as the time of the accident, the vehicle's location, and the severity of the accident.

[0060] After receiving the signal, the ground control center first performs a self-check. Once it confirms that the system is fault-free, it immediately controls the drone's cabin door to open and powers on the drone.

[0061] The drone takes off automatically and flies to the calculated warning position, 150 meters behind the vehicle, according to a pre-programmed sequence. During flight, the drone uses obstacle avoidance sensors to perceive the surrounding environment in real time and dynamically adjusts its flight path to avoid obstacles. The flight altitude is controlled at around 10 meters to ensure stability and visibility.

[0062] Upon reaching the target location, the drone automatically hovers at a height of 10 meters, simultaneously activating its LED strobe lights and electronic siren. The warning signals flash and sound at a specific frequency to maximize the attention of vehicles behind. The drone maintains a stable position through its positioning module and flight control system, with a deviation of no more than ±1 meter even under wind interference.

[0063] The drone will automatically return to base when any of the following conditions are met:

[0064] Users can issue a return command via a mobile app or a button in the vehicle.

[0065] The drone's battery level is below 20%.

[0066] Received a remote return instruction from the traffic management center.

[0067] During the return journey, the drone continued to perform obstacle avoidance procedures and ultimately landed precisely inside the drone cabin. After the cabin door closed, the system entered standby mode.

[0068] This invention eliminates the life safety risks of manually setting up warning signs, achieves a rapid early warning response with "zero delay" after an accident, provides long-distance, high-intensity, and more conspicuous sound and light alarm signals, and realizes full automation and intelligence in the early warning process.
