[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0032] In various embodiments of the present application, it should be understood that the magnitudes of the serial numbers of the following processes do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0033] As Figure 1 shown, the embodiments of the present application provide a traffic event warning method, which is applied to a warning device. The warning device includes an aircraft component and a road warning component. The method includes:

[0034] Step 101, receiving a first flight control instruction carrying a target parking position sent by a traffic event warning platform; wherein, the target parking position is determined by the traffic event warning platform based on the traffic event information corresponding to the target traffic event to be warned carried in the traffic event warning request when receiving the traffic event warning request.

[0035] The traffic incident warning platform corresponds to multiple warning devices, which can be placed at the same device storage point or at different device storage points. For example, multiple device storage points can be scattered within the jurisdiction area corresponding to the traffic incident warning platform. A communication connection is established between the traffic incident warning platform and each warning device. Based on this communication connection, the traffic incident warning platform can send control instructions to the warning devices, and the warning devices can feedback various information to the traffic incident warning platform, such as real-time location information, video information of traffic incidents, etc.

[0036] As the command center of multiple warning devices, the traffic incident warning platform can receive traffic incident warning requests through multiple channels. For example, the traffic incident warning platform can communicate with a road monitoring system used to monitor whether there are traffic incidents to be warned on the road to obtain whether there are traffic incidents to be warned on the roads within its jurisdiction. Once the road monitoring system detects a target traffic incident to be warned, it immediately obtains the traffic incident information corresponding to the target traffic incident and triggers a traffic incident warning request to the traffic incident warning platform. The traffic incident warning request carries the traffic incident information corresponding to the target traffic incident. The traffic incident warning platform can also communicate with the in-vehicle terminals and mobile terminals of traffic patrol personnel. When traffic patrol personnel detect a traffic incident to be warned, they can trigger a traffic incident warning request to the traffic incident warning platform through the in-vehicle terminal or mobile terminal.

[0037] Optionally, the traffic incident information includes the precise geographical location where the traffic incident occurred, and can also include the event type, such as vehicle collision accidents, road construction, vehicle breakdowns, etc., and can also include the severity of the traffic incident, etc.

[0038] The traffic incident warning platform determines at least one warning device for warning the target traffic incident and the corresponding target parking position for each warning device based on the traffic incident information corresponding to the target traffic incident to be warned carried in the traffic incident warning request.

[0039] The warning device receives the first flight instruction carrying the target parking position sent by the traffic incident warning platform. This instruction is transmitted through wireless communication technologies, such as 4G, 5G, or even future 6G networks, to ensure that the instruction can be received by the warning device quickly and accurately.

[0040] Step 102: In response to the first flight control instruction, fly to the target parking position through the aircraft component and warn the target traffic incident through the road warning component.

[0041] After the warning device receives the first flight control instruction, the aircraft component responds quickly. The aircraft component generally uses a multi-rotor UAV or a fixed-wing UAV, which are equipped with high-precision navigation systems, such as a combination of an inertial navigation system and a satellite navigation system. These navigation systems can obtain real-time information such as the position and attitude of the aircraft, and plan the optimal flight path according to the target parking position in the first flight control instruction. Whether in urban roads, highways, or in remote mountainous areas and other different terrains and traffic environments, the aircraft component can fly flexibly to the designated position, and the road warning component can also give effective warnings according to the actual situation. For example, when an accident occurs on a mountain road, traditional warning methods may be difficult to implement due to complex terrain, while this warning method is not restricted by terrain and can play a role in a timely manner.

[0042] During the flight, the aircraft component will also use various sensors carried by itself, such as obstacle avoidance sensors (ultrasonic sensors, lidar, etc.), barometric pressure sensors, gyroscopes, etc., to ensure flight safety. For example, when encountering bad weather (such as strong winds, heavy rains, etc.) or air obstacles (such as birds, other aircraft, etc.), the obstacle avoidance sensor can detect and feedback to the control system of the aircraft in time, and the control system will automatically adjust the flight path to avoid danger.

[0043] When the warning device flies to the target parking position through the aircraft component, the road warning component begins to play a role. The road warning component can use various forms for traffic warning. For example, it can play warning messages in a loop through a speaker, such as "Accident ahead, slow down" "Road construction, pay attention to avoidance", etc.; it may also use a strong light warning light to attract the attention of drivers of passing vehicles through flashing lights at night or in a dim environment. In addition, the shape of the road warning component can be set to a cone shape.

[0044] Exemplarily, a vehicle rear-end traffic accident occurred on an urban arterial road, resulting in one lane being occupied. The road monitoring system detected this traffic event and sent a traffic event warning request to the traffic event warning platform. After receiving the traffic event warning request, the traffic event warning platform determined the warning device and the target parking position. The optional target parking position can be the roadside 200 meters behind the accident scene. The aircraft component of the warning device quickly flew to this position, the strong light warning light of the road warning component began to flash, and at the same time the speaker was turned on to remind passing vehicles to pay attention to avoidance. The drivers of passing vehicles could clearly see and hear these warning messages in the distance, and made preparations for deceleration and avoidance in advance, effectively avoiding the occurrence of secondary accidents.

[0045] In the above embodiments of the present application, when a target traffic event to be warned occurs, the warning device receives a first flight control instruction carrying the target parking position sent by the traffic event warning platform, and according to the first flight control instruction, flies to the target parking position through the aircraft component, and warns the target traffic event through the road warning component. By means of the aircraft component that is not restricted by terrain and traffic conditions, it can fly to the location where the target traffic event occurs in a short time, so that it can quickly intercept, divert and warn passing vehicles after the target traffic event occurs, improving the traffic event warning efficiency and avoiding traffic accidents. At the same time, the warning device reaches the location where the target traffic event occurs by flying, reducing the need for manual warning at the accident scene, and reducing the labor cost and the risk of personnel working in a dangerous environment.

[0046] In an alternative embodiment of the present application, the warning device further includes a positioning module and an image acquisition module, and the method further includes:

[0047] Obtain real-time position information through the positioning module, and send the real-time position information to the traffic event warning platform;

[0048] When the real-time position information indicates that the warning device is located within the preset area range corresponding to the target parking position, collect image information corresponding to the target traffic event through the image acquisition module, and send the image information to the traffic event warning platform.

[0049] The warning device provided by the embodiment of the present application is also provided with a positioning module and an image acquisition module. Among them, the positioning module can be a GPS / Beidou positioning module, which adopts the fusion technology of GPS positioning and Beidou positioning, and processes a variety of positioning data through algorithms to ensure the accurate positioning of the warning device in closed space scenarios such as tunnels and underground parking lots, and improve the positioning ability in complex environments. The image acquisition module can be a high-definition camera, so as to be able to take an all-round picture of the traffic event scene with ultra-high resolution, ensuring the acquisition of clear, comprehensive and valuable image information.

[0050] Specifically, the warning device can obtain real-time position information through the positioning module, and transmit the obtained real-time position information to the traffic event warning platform through the communication module built in the warning device, so that the traffic event warning platform can monitor the dynamics of the warning device in real time.

[0051] In addition, to obtain the on-site situation of the target traffic event, such as the degree of vehicle damage, the progress of road construction, the road conditions, etc., when the real-time position information collected by the positioning module indicates that the warning device has reached the preset area range corresponding to the target parking position, the image acquisition module in the embodiments of the present application can capture the on-site situation of the target traffic event to obtain image information, and transmit the obtained image information to the traffic event warning platform through the communication module built in the warning device. Among them, the warning device starts image acquisition when it reaches the preset area range corresponding to the target parking position, and can capture a more complete on-site situation of the traffic event. Exemplarily, when the target traffic event is a traffic accident, the image acquisition module can not only capture the deformation details after the severe collision of the accident vehicle, such as the degree of distortion of the vehicle head and the concave parts of the vehicle body, but also clearly record the length, starting position and direction of the braking marks, as well as the distribution of vehicle parts and debris scattered on the road surface. After obtaining these images through the traffic event warning platform, the traffic management department can quickly and accurately evaluate the severity of the accident. By analyzing information such as the collision angle of the vehicle, the length and direction of the braking marks, and combining the vehicle dynamics model and the accident reconstruction algorithm, the driving speed, driving trajectory of each vehicle at the time of the accident and the general process of the accident can be roughly inferred, providing solid data support for more accurate subsequent liability determination and accident handling.

[0052] It should be noted that the communication link between the communication module built in the warning device and the traffic event warning platform can be established based on 4G or 5G networks, or a dedicated wireless transmission frequency band can be used to ensure the security and stability of data transmission. When transmitting based on 4G or 5G networks, the mature encryption technology and strong anti-interference ability are used to ensure the secure transmission of image data; when using a dedicated wireless transmission frequency band, through reasonable frequency planning and signal modulation technology, interference with other communication signals is avoided, ensuring that the image data can be quickly and stably transmitted to the platform.

[0053] In the above implementation scheme of the present application, by feeding back the real-time position information and the image information collected when reaching the warning area range of the target parking position to the traffic event warning platform, the warning device can enable the traffic event warning platform to grasp the positions of each warning device and the on-site situation of the target traffic event in real time, so as to adjust the positions of the warning devices and the warning methods adopted by the warning devices according to the on-site situation, improve the warning efficiency, and avoid traffic accidents.

[0054] In an alternative embodiment of the present application, the method further includes:

[0055] Receiving a second flight control instruction carrying the device storage position sent by the traffic event warning platform; wherein, the device storage position is determined by the traffic event warning platform when receiving a warning cancellation request corresponding to the target traffic event;

[0056] In response to the second flight control instruction, fly to the equipment storage location through the aircraft component.

[0057] Specifically, after a target traffic event occurs, when the traffic event warning platform receives a traffic event warning request, it controls the warning equipment to fly to the location where the target traffic event occurs to warn the target traffic event. When the target traffic event is eliminated and traffic warning is no longer required, it is necessary to promptly retrieve the warning equipment parked here, that is, send a warning cancellation request for the target traffic event to the traffic event warning platform. This warning cancellation request can be sent by the traffic management department to the traffic event warning platform through a dedicated system after the traffic event is processed and the road resumes normal traffic; it can also be reported by on-site staff using a mobile terminal after confirming that the traffic event has been properly resolved, or it can be triggered when the traffic event warning platform analyzes from the image information fed back by the warning equipment that the target traffic event has been lifted.

[0058] Once the traffic event warning platform receives the warning cancellation request, it will determine the equipment storage locations of each warning equipment. The equipment storage locations are determined according to the distribution of surrounding equipment storage sites, the current location of the warning equipment, battery life, etc., in order to facilitate centralized management and reallocation of the equipment, and reduce the time and energy consumption required for the equipment to return.

[0059] The warning equipment receives the second flight control instruction carrying the equipment storage location sent by the traffic event warning platform and flies to the equipment storage location through the aircraft component. Specifically, the flight controller in the aircraft component extracts the detailed coordinate information of the equipment storage location and plans the optimal flight path to the equipment storage location. When planning the path, it will comprehensively consider many factors, such as the terrain and landform of the flight area, avoiding obstacles such as high mountains and high-rise buildings; meteorological conditions, avoiding flying in bad weather such as strong winds and heavy rains; and air traffic control rules to ensure that the flight process complies with relevant regulations and does not conflict with other aircraft.

[0060] For example, in the handling of a traffic accident in a certain city, a freight truck collided with a car on the main road, causing traffic congestion and injuries. The warning equipment quickly arrived at the scene for warning and information collection. When the accident was handled, the traffic police sent a warning cancellation request through the traffic event warning platform. The platform determined a traffic police brigade station near the scene as the equipment storage location based on the location of nearby equipment storage sites and sent the second flight control instruction to the warning equipment. The aircraft component of the warning equipment was activated and flew smoothly to the traffic police brigade station along the planned flight path, avoiding surrounding high-rise buildings and dense aerial cables, and completing the recovery of the equipment.

[0061] In the above embodiments of the present application, the warning device can improve the recovery efficiency of the warning device by receiving the second flight control instruction and flying to the device storage location. At the same time, by enabling the device to return to the reserve state as soon as possible, it is beneficial to the centralized management and maintenance of the device, and can also respond to the next traffic event at any time.

[0062] In an alternative embodiment of the present application, the warning device further includes an obstacle avoidance component. After flying to the target parking position through the aircraft component, the method further includes:

[0063] Detecting whether there is a target obstacle within a preset range of the warning device, where the target obstacle has a moving speed greater than a preset speed threshold and a moving direction towards the warning device;

[0064] When the target obstacle is detected, obtaining the surrounding environment information corresponding to the warning device; determining a target safe position according to the surrounding environment information, the moving direction and moving speed of the target obstacle, and the distance between the target obstacle and the warning device;

[0065] Sending an obstacle avoidance control instruction carrying the target safe position to the obstacle avoidance component, so that the obstacle avoidance component drives the warning device to move to the target safe position.

[0066] Considering that the traffic environment near the occurrence point of the target traffic event is complex and changeable, after the warning device flies to the target parking position, in order to ensure the safety of the warning device and avoid damage to the warning device caused by being collided by a vehicle, an obstacle avoidance component is also provided on the warning device. The obstacle avoidance component at least includes a distance sensor, a speed sensor, a drive motor and rollers.

[0067] In the embodiments of the present application, after the warning device is parked at the target parking position, the distance sensor and the speed sensor cooperate to monitor the situation within the preset range of the warning device, and potential danger hazards are detected in time. Specifically, it can be determined whether there is a target obstacle within the preset range of the warning device. Here, the target obstacle refers to an obstacle with a moving speed greater than the preset speed threshold and a moving direction towards the warning device. Exemplarily, when the target traffic event is a road construction event, the target parking position of the warning device is on the roadside. During the construction process, the warning device emits a warning reminder to passing vehicles through a warning light and a speaker playing a voice prompt. At this time, if a car rushes towards the direction where the warning device is located quickly due to the driver's fatigue driving and inattention, resulting in the vehicle losing control, the vehicle will be detected and determined as a target obstacle. Correspondingly, the warning device will activate an obstacle avoidance plan to quickly move to a safe position to avoid being hit and damaged by the vehicle.

[0068] Specifically, the distance sensor can be a lidar or an ultrasonic sensor, which is used to detect whether there is an obstacle within the preset range of the warning device and the distance between the obstacle and the warning device. The speed sensor can detect the moving speed of the obstacle within the preset range of the warning device. Based on the obstacle information collected by the distance sensor and the speed sensor, specifically including speed information and distance information, it is then determined whether there is a target obstacle within the preset range of the warning device whose moving speed is greater than the preset speed threshold and whose moving direction is towards the warning device by analyzing the obstacle information.

[0069] It should be noted that the preset range and the preset speed threshold can be flexibly adjusted according to the different requirements of the actual application scenario. For example, in urban roads, due to the relatively low vehicle speed and complex road conditions, the preset range is usually set as a circular area with a radius of 10 meters, and the preset speed threshold is set at 20 km / h to ensure that the obstacle avoidance component can timely detect the target that may pose a threat to the warning device in the urban environment. On highways, considering the relatively high vehicle speed and long braking distance, the preset range may be expanded to a radius of 30 meters, and the preset speed threshold is increased to 60 km / h to detect abnormal vehicles approaching from afar in advance and reserve sufficient reaction time for the obstacle avoidance action.

[0070] When the warning device detects a target obstacle and determines that there is a collision risk, at this time, it is necessary to activate the obstacle avoidance plan. First, determine the target safe position that will not be collided by the target obstacle, and then move to the target safe position.

[0071] When determining the target safe position, multiple key factors need to be comprehensively considered, such as the surrounding environment information of the warning device, the moving direction and moving speed of the target obstacle, and the distance between the target obstacle and the warning device. Specifically, first, it is necessary to analyze the movable space in the surrounding environment of the warning device. For example, by comprehensively interpreting the three-dimensional point cloud map and the image recognition results, immovable obstacles such as buildings and large fixed equipment, as well as busy areas with dense traffic flow and unsuitable for the movement of the warning device, are identified and excluded from the selectable range. Then, according to the real-time movement trajectory of the target obstacle, the kinematic principles and prediction models in physics are used to accurately predict its future movement trend and calculate the possible collision points. Search for potential safe positions in the direction away from these predicted collision points. During the search process, the moving ability and stability of the warning device itself are fully considered. The moving ability of the warning device is restricted by its power system, the performance of the driving wheels, and the flexibility of the steering mechanism. Therefore, positions that can be reached within the moving ability range of the warning device are preferentially selected. At the same time, in order to ensure the stability during the obstacle avoidance process, areas with complex terrain, large slopes, or uneven ground also need to be avoided, and relatively flat, open, and easily passable positions are selected as the target safe positions.

[0072] After determining the target safe position, the warning device sends an obstacle avoidance control instruction carrying the target safe position to the built-in obstacle avoidance component, so that the obstacle avoidance component drives the warning device to move to the target safe position.

[0073] Specifically, the obstacle avoidance component includes a driving device, which is composed of a driving motor, rollers and a steering mechanism. Among them, the driving motor is the power source of the driving device, and is used to quickly start and output torque when the obstacle avoidance component receives the obstacle avoidance control instruction, provide power for the driving wheels, so that the rollers rotate, and push the warning device to move towards the target safe position. The steering mechanism is used as the steering wheel of the driving device, and is used to determine the moving direction of the warning device according to the direction where the target safe position is located. The steering mechanism works in coordination with the driving motor to achieve precise steering of the warning device, and can also flexibly adjust the steering angle according to the real-time road conditions and changes in the surrounding environment, ensuring that the warning device can accurately move to the target safe position along the predetermined obstacle avoidance path.

[0074] It should be noted that the obstacle avoidance component is also built-in with sensors such as an acceleration sensor and a gyroscope to obtain key information such as the speed, acceleration, and attitude of the warning device in real time during the movement towards the target safe position. At the same time, during the movement towards the target safe position, it is also necessary to continuously pay attention to the dynamic changes in the surrounding environment and the real-time position of the target obstacle. Once it is found that there are sudden changes in the surrounding environment, such as the appearance of new obstacles or unexpected changes in the movement trajectory of the target obstacle, the obstacle avoidance component immediately feeds back this information to the control system of the warning device. The control system will recalculate the obstacle avoidance path and movement parameters according to the new information, and send updated instructions to the obstacle avoidance component in a timely manner to dynamically adjust the moving speed and direction of the warning device, ensuring the safety and smoothness of the entire obstacle avoidance process.

[0075] In the above implementation scheme of the present application, when it is detected that there is a target obstacle within the preset range of the warning device whose moving speed is greater than the preset speed threshold and the moving direction is towards the warning device, according to the surrounding environment information, the moving direction and moving speed of the target obstacle, and the distance between the target obstacle and the warning device, the target safe position is determined, and an obstacle avoidance control instruction carrying the target safe position is sent to the obstacle avoidance component, so that the obstacle avoidance component drives the warning device to move to the target safe position, which can quickly take avoidance measures when the warning device is at risk of collision, reduce the probability of the warning device being damaged by collision, and thus effectively extend the service life of the warning device.

[0076] In an optional embodiment of the present application, the method further includes:

[0077] Receiving the device information of other warning devices corresponding to the target traffic event sent by the traffic event warning platform;

[0078] Based on the device information, establish a communication connection with the other warning devices;

[0079] When the target obstacle is detected, the method further includes:

[0080] Based on the communication connection with the other warning devices, send obstacle avoidance notification information to the other warning devices, so that the other warning devices can avoid the target obstacle.

[0081] In the embodiments of the present application, after receiving a traffic event warning request, the traffic event warning platform first determines the required number of warning devices corresponding to the target traffic event according to the traffic event information corresponding to the target traffic event to be warned carried in the traffic event warning request. For different traffic events, the required number of warning devices may be different.

[0082] For scenarios where multiple warning devices need to work together, the traffic event warning platform will send first flight control instructions to multiple warning devices respectively, so that these multiple warning devices can all fly to the location where the target traffic event occurs to warn the target traffic event. The cooperation of multiple warning devices can achieve a larger range of traffic control and safety protection.

[0083] When a warning device participates in the warning task of a target traffic event, it will receive the device information of other warning devices sent by the traffic event warning platform. Here, the other warning devices refer to the warning devices that also participate in the warning task of the target traffic event. Among them, the device information at least includes the identification information, model, communication parameters, working status, and current location of other warning devices. The warning device establishes a communication connection with other warning devices according to the device information of other warning devices, thus realizing a data communication link established by all warning devices corresponding to the target traffic event through an ad hoc network method. Here, the ad hoc network technology is usually based on wireless communication protocols such as Wi-Fi, Bluetooth Mesh, or ZigBee, etc., and can quickly and stably transmit data between multiple warning devices.

[0084] When a certain warning device detects a target obstacle, it will send obstacle avoidance notification information to other warning devices based on the established communication connection. The obstacle avoidance notification information contains detailed information about the target obstacle, such as location, speed, direction, size, and possible collision time, etc. After receiving the notification, other warning devices will immediately activate their own obstacle avoidance mechanisms.

[0085] Other warning devices can, based on the received obstacle information, combine their own positions and surrounding environment information, and use the previously mentioned autonomous navigation and obstacle avoidance solutions to calculate the best avoidance paths and methods. Exemplarily, on a highway, when a warning device detects an out-of-control truck rushing towards a group of warning devices ahead, it will immediately send an obstacle avoidance notice to other warning devices. After receiving the notice, other warning devices, based on their own positions and the conditions of the surrounding lanes, some choose to move to the emergency lane, while some adjust the warning angle to ensure that while avoiding the truck, they can continue to effectively warn passing vehicles.

[0086] In addition, each warning device is equipped with a high-precision map module. These map data not only contain basic road information such as road directions, number of lanes, intersection positions, etc., but also cover detailed geographical information such as terrain and landforms, building distributions, traffic facility positions, etc. Based on the data communication links established through the ad hoc network method, these multiple warning devices can share the map information they possess, thus building a comprehensive and accurate shared map database. In this database, the map information is dynamically updated according to real-time road conditions and environmental changes to ensure that each warning device can obtain the latest map data. With the help of the shared map information and their respective positioning modules, each warning device can determine its own precise position and the positions of other warning devices. The warning devices can interact with each other in real time to exchange obstacle avoidance information and cooperate to adjust the obstacle avoidance strategies to avoid mutual interference.

[0087] Exemplarily, the target traffic event is a traffic accident that occurred on a highway, and multiple warning devices are deployed around the accident site for warning. Among them, warning device A first detects an out-of-control truck rushing towards the group of warning devices quickly, with a speed far exceeding the normal driving speed and a moving direction towards warning device A. While avoiding, warning device A sends an obstacle avoidance notice message to other warning devices, detailing the position, speed, direction, and estimated arrival time of the out-of-control truck. After receiving the notice, warning device B analyzes its own position and the surrounding environment, and finds that there is an empty emergency lane beside it, so it quickly adjusts its position and moves onto the emergency lane, successfully avoiding a possible collision. Warning devices C and D also take corresponding avoidance measures according to their own situations to ensure their own safety and avoid being damaged by the out-of-control vehicle.

[0088] In the above implementation scheme of this application, by establishing a communication connection between other warning devices corresponding to the target traffic event, when a danger is detected, other warning devices can be notified in a timely manner, reducing the risk of damage to the warning devices. At the same time, through cooperative obstacle avoidance, sudden situations can be better handled, improving the reliability and stability of the warning system.

[0089] In an alternative embodiment of the present application, the road warning component includes a speaker and / or a warning light. Warning the target traffic event through the road warning component includes:

[0090] Sending a play instruction to the speaker to cause the speaker to play a prompt message for traffic event warning; and / or

[0091] Sending a turn-on instruction to the warning light to cause the warning light to turn on.

[0092] Specifically, a speaker can be provided on the road warning component. After the warning device reaches the target parking position, a prompt message can be played through the speaker. Specifically, a play instruction is sent to the speaker, and the play instruction carries the play content, which can be determined according to the warning type of the target traffic event. For example, at the scene of a traffic accident, the play content can be "There is an accident ahead. Please slow down and pay attention to avoidance", reminding passing drivers to make preparations for deceleration and avoidance in advance through clear and loud voices, and avoiding the occurrence of secondary accidents. In the scenario of road construction, the play content can be "Road construction ahead. Please pay attention to safety", enabling drivers to be aware of the road conditions in advance and plan their driving routes.

[0093] In addition, a warning light can also be provided on the road warning component. After the warning device reaches the target parking position, a turn-on instruction is sent to the warning light to cause the warning light to turn on. Specifically, the warning light can attract the attention of passing vehicle drivers through flashing or constantly lit lights, arousing the driver's alertness to enhance the warning effect.

[0094] In the above implementation of the present application, through the sound prompt of the speaker and the visual warning of the warning light, the senses of the driver are stimulated from both the auditory and visual aspects, effectively improving their attention to traffic events, enabling them to react in a timely manner, enhancing the warning effect, reducing the probability of traffic accidents, and further reducing the occurrence of traffic jams to ensure the smooth flow of the road.

[0095] In an alternative embodiment of the present application, the road warning component includes a telescopic component and a warning light provided on the telescopic component; the method further includes:

[0096] Receiving a lifting instruction sent by the traffic event warning platform;

[0097] In response to the lifting instruction, lifting the warning light from a first position to a second position through the telescopic component, where the second position is higher than the first position.

[0098] In the embodiments of the present application, the warning light in the road warning component is arranged on a telescopic component, and through this telescopic component, the height of the warning light can be changed. Optionally, the telescopic component can be an electric telescopic component, that is, by using the rotational movement of the motor, the telescopic rod in the telescopic component is telescoped, and thus the height of the warning light installed on the telescopic rod is changed.

[0099] Specifically, the traffic event warning platform can judge whether it is necessary to raise the position of the warning light in the warning device according to the image information corresponding to the target traffic event fed back by the received warning device, so as to achieve a better warning effect. If necessary, the traffic event warning platform sends a lifting instruction to the warning device.

[0100] After receiving the lifting instruction sent by the traffic event warning platform, the warning device sends a control signal to the motor of the telescopic component, so that the motor operates to drive the telescopic rod to extend, and the warning light is lifted from the first position to the second position, completing the lifting operation. By raising the warning light, the driver of the passing vehicle can see the warning light when the distance from the place where the target traffic event occurs is relatively far, so as to decelerate and avoid in advance.

[0101] In the above implementation scheme of the present application, the warning light is lifted from a lower position to a higher position through the lifting component, which can effectively expand the warning range, enable the driver to discover the warning signal at a farther distance, make preparations in advance, and reduce the occurrence probability of traffic accidents.

[0102] In an optional embodiment of the present application, a light strip and a photosensitive sensor are arranged on the road warning component. Warning the target traffic event through the road warning component includes:

[0103] Detecting the ambient light intensity through the photosensitive sensor;

[0104] When the ambient light intensity is less than the preset light intensity threshold, controlling the light strip to be turned on.

[0105] Considering that currently in scenarios such as road construction and traffic accident sites, traffic cones (also known as warning cones and warning posts) are usually used for traffic warning and restricting the passing range of vehicles and pedestrians. In the embodiments of the present application, the outer shape of the road warning component can be set to the shape of a traffic cone, and a light strip (LED light strip) and a photosensitive sensor can be arranged on the surface of the road warning component. In addition, in order to save energy and protect the environment, a solar panel can be installed on the traffic cone to supply power to the light strip and the photosensitive sensor. Optionally, the solar panel can be embedded inside the placement groove of the traffic cone to avoid being bumped in a complex traffic environment.

[0106] When warning a target traffic event through a road warning component, the photosensitive sensor continuously detects the ambient light intensity. The warning device compares the ambient light intensity detected by the photosensitive sensor with a preset light intensity threshold, which can be determined through a large number of experiments and data analyses according to the actual traffic scenario and warning requirements. When the ambient light intensity is higher than the preset light intensity threshold, the control strip light is turned on. Thus, when there is sufficient sunlight during the day, the strip light is not controlled to be turned on. When it enters the night or encounters bad weather (such as heavy rain, fog, sandstorm, etc.) resulting in dim light, the strip light is controlled to be turned on, making the road warning component more prominent, capable of attracting the attention of drivers of passing vehicles from a long distance, and thus driving carefully.

[0107] Optionally, a reflective coating is provided on the outer surface of the strip light. In this way, during the day, even when the strip light is in the off state, the reflective coating can reflect the light back, forming a strong visual warning effect.

[0108] In the above implementation of the present application, by setting a strip light and a photosensitive sensor on the road warning, when the ambient light intensity is lower than the preset light intensity threshold, the warning effect can be enhanced through the strip light, improving the adaptability and reliability of the warning device to complex environments and reducing the risk of traffic accidents.

[0109] As Figure 2 shown, an embodiment of the present application provides a traffic event warning method, which is applied to a traffic event warning platform. The traffic event warning platform corresponds to multiple warning devices. Among them, the warning device includes an aircraft component and a road warning component. The method includes:

[0110] Step 201, receiving a traffic event warning request, where the traffic event warning request carries traffic event information corresponding to the target traffic event to be warned.

[0111] In the embodiment of the present application, the traffic event warning platform corresponds to multiple warning devices. These multiple warning devices can be parked at the same device storage point or at different device storage points. For example, multiple device storage points can be scattered in the jurisdiction area corresponding to the traffic event warning platform. A communication connection is established between the traffic event warning platform and each warning device.

[0112] As the command center for multiple warning devices, the traffic incident warning platform can receive traffic incident warning requests through multiple channels and always maintain a monitoring state for various traffic incident information. For example, the traffic incident warning platform can communicate with a road monitoring system used to monitor whether there are traffic incidents to be warned on the road to obtain whether there are traffic incidents to be warned on the roads within its jurisdiction. Once the road monitoring system detects a target traffic incident to be warned, it immediately obtains the traffic incident information corresponding to the target traffic incident and triggers a traffic incident warning request to the traffic incident warning platform. The traffic incident warning request carries the traffic incident information corresponding to the target traffic incident. The traffic incident warning platform can also communicate with the in-vehicle terminals of traffic patrol personnel. When traffic patrol personnel detect a traffic incident to be warned, they can trigger a traffic incident warning request to the traffic incident warning platform through the in-vehicle terminal.

[0113] Specifically, the traffic incident information carried in the traffic incident warning request includes, but is not limited to: incident type, occurrence location, severity, etc.

[0114] Step 202: Determine N target warning devices from multiple warning devices according to the traffic incident information, and determine the target parking positions corresponding to each target warning device; N is an integer greater than or equal to 1.

[0115] Based on the traffic incident information carried in the traffic incident warning request corresponding to the target traffic incident to be warned, the traffic incident warning platform screens out N target warning devices from multiple warning devices to perform the warning task for the target traffic incident. Among them, the screening process can be based on the distribution of these multiple warning devices, and preferentially select the devices closer to the target traffic incident site to ensure that they can quickly respond and reach the target traffic incident site. At the same time, it is also necessary to select devices with good working status according to the working status of the warning devices, such as whether the device battery is sufficient and whether all functions are operating normally.

[0116] The traffic incident warning platform also needs to determine the target parking positions corresponding to these N target warning devices. Specifically, it can be determined according to factors such as the actual situation of the scene, surrounding road conditions, and traffic flow included in the traffic incident information of the target traffic incident. For example, at the scene of a traffic accident, the target parking position can be selected in the surrounding safe area of the accident scene, which should be able to clearly warn passing vehicles and avoid interfering with the rescue work. If it is a road construction scenario, the parking position of the warning device will be determined according to the boundary of the construction area, the vehicle detour route, etc., to ensure that the construction area is comprehensively and effectively warned. At the same time, if the number of target warning devices is multiple, these multiple target warning devices also need to be dispersed to guide passing vehicles.

[0117] Step 203: Send a first flight control instruction carrying the target parking position to the target warning device, so that the target warning device flies to the target parking position through the aircraft component and warns of the target traffic event through the road warning component.

[0118] After determining the target traffic warning device and the corresponding target parking position, the traffic event warning platform sends a first flight control instruction to the target warning device based on the communication connection with the target warning device. After receiving the first flight control instruction, the aircraft component of the target warning device responds quickly, plans the optimal flight path, and flies to the target parking position. After arriving at the target parking position, the road warning component starts to play its role.

[0119] Specifically, the road warning component includes various warning devices such as speakers, warning lights, and light strips. Thus, the drivers of passing vehicles can clearly see and hear the warning information from a distance, make preparations for deceleration and avoidance in advance, and effectively avoid the occurrence of secondary accidents.

[0120] In the above implementation of this application, after receiving a traffic event warning request, the traffic event warning platform first determines the target warning device for warning the target traffic event according to the traffic event information, and then sends a first flight control instruction to each target warning device, so that each target warning device can fly to the location where the target traffic event occurs in a short time with the help of the aircraft component that is not restricted by terrain and traffic conditions. Thus, it can quickly intercept, divert, and warn passing vehicles after the target traffic event occurs, improving the efficiency of traffic event warning and avoiding traffic accidents. At the same time, by controlling the warning to reach the location of the target traffic event in a flying manner, the need for manual warning at the accident scene is reduced, and the labor cost and the risk of personnel working in a dangerous environment are lowered.

[0121] In an optional embodiment of this application, according to the traffic event information, determining N target warning devices from the multiple warning devices and determining the target parking position corresponding to each target warning device includes:

[0122] According to the traffic event information, determine the location and type of the target traffic event;

[0123] According to the event type, determine the required number of warning devices corresponding to the target traffic event;

[0124] According to the position information corresponding to the multiple warning devices and the location of the target traffic event, select the required number of warning devices from the multiple warning devices to obtain the N target warning devices;

[0125] According to the occurrence location of the target traffic event and the event type, the target parking locations corresponding to the N target warning devices are determined.

[0126] Specifically, after receiving the traffic event warning request, the traffic event warning platform first parses the traffic event information carried therein to determine the location and type of the target traffic event to be warned. For example, when relevant personnel send a traffic event warning request to the traffic event warning platform through a terminal device, they need to fill in information such as the event type and location.

[0127] Different types of events require different numbers of warning devices. Here, the corresponding relationship between the event type and the number of warning devices required can be determined in advance based on the analysis of a large number of traffic event cases, and then the number of warning devices required corresponding to the event type of the target traffic event can be determined based on the corresponding relationship. For example, when the event type is a minor traffic accident, only 2 to 3 warning devices are needed, which are placed in front and behind the accident vehicle to serve as a warning. When the event type is a major traffic accident, considering the large scope of the accident site and the need for passing vehicles to know in advance and slow down to avoid from a long distance, 5 to 8 warning devices may be required. When the event type is road construction, the number of requirements is determined based on the length, complexity and surrounding traffic flow of the construction area. If it is a 100-meter-long ordinary road maintenance construction and the surrounding traffic volume is small, 4 to 5 warning devices may be required; if the construction area is 500 meters long and is located near a transportation hub with a large traffic volume, then 10 to 15 warning devices may be required to ensure that the construction area is fully warned.

[0128] After obtaining the required number of warning devices, the traffic incident warning platform is based on the location information corresponding to multiple warning devices. The warning devices here are warning devices that are idle and in good working condition (such as sufficient power and normal communication). Then, according to the distance between each warning device and the location of the target traffic incident, the warning devices are sorted from near to far, and the warning devices with the highest number of warning devices in the sorting are selected and determined as N target warning devices.

[0129] The traffic incident warning platform also needs to further determine the target parking positions corresponding to the N target warning devices according to the location of the target traffic incident and the type of incident.

[0130] For example, for a minor traffic accident, the target warning device can be placed 200 meters behind the accident vehicle. For road construction, if the construction area is located on one side of the road, the target warning device needs to be placed at intervals at the edge of the construction area to clearly define the boundary of the construction area.

[0131] In the above implementation of the present application, by determining the required quantity of early warning devices and the target parking positions of each target early warning device, overuse or insufficiency of early warning devices can be avoided, and it can also ensure that the early warning devices can play a warning role at the most suitable positions, improve the warning effect, and guarantee road traffic safety.

[0132] In an alternative embodiment of the present application, after sending the first flight control instruction carrying the target parking position to the target early warning device, the method further includes:

[0133] Obtaining real-time position information of the target early warning device;

[0134] When the real-time position information indicates that the target early warning device is located within the preset area range corresponding to the target parking position, obtaining image information corresponding to the target traffic event collected by the target early warning device.

[0135] Specifically, after the traffic event early warning platform issues the first flight control instruction, the staff needs to master the dynamics of each target early warning device in real time, especially the real-time position information. Among them, a positioning module is set on each early warning device, and this positioning module can be a positioning system integrating GPS and Beidou satellite positioning technologies to ensure the accuracy of position information.

[0136] The target early warning device can transmit the collected real-time position information to the traffic event early warning platform through a wireless communication link, such as a 4G or 5G network. Optionally, after the traffic event early warning platform obtains the real-time position information of the target early warning device, it can compare it with the target parking position to obtain the remaining flight distance and display it on the monitoring interface of the traffic event early warning platform, facilitating the staff to master the dynamics of each target early warning device in real time.

[0137] Specifically, image acquisition devices such as high-definition cameras are equipped on the target early warning device. When the target early warning device approaches the target parking position and is located within the preset area range of the target parking position, the traffic event early warning platform can send a control instruction to it to enable its image acquisition function, shoot the target traffic event site, and transmit the captured image information to the traffic event early warning platform. After the traffic event early warning platform obtains the image information, it can display it on the monitoring interface, enabling the staff to view the event site images collected by each target early warning device in real time, timely adjust the traffic guidance plan, reasonably plan the vehicle detour route, minimize the impact of the target traffic event on normal traffic to the greatest extent, and improve the utilization efficiency of road resources. Exemplarily, in a bridge construction project, through real-time monitoring by the image acquisition module, it is found that the traffic flow on the originally scheduled detour route is too large, and the detour route is adjusted to another route in a timely manner by adjusting the placement position of the early warning device, effectively avoiding traffic congestion.

[0138] In the above implementation of the present application, by obtaining the location information of the target warning device in real time and monitoring it, the reliability of the warning device deployment can be improved. By obtaining image information, the on-site situation of the target traffic event can be grasped in a timely manner, so as to adjust the warning plan in real time according to the on-site situation and ensure road traffic safety.

[0139] In an alternative embodiment of the present application, the method further includes:

[0140] Receiving a warning cancellation request corresponding to the target traffic event;

[0141] In response to the warning cancellation request, sending a second flight control instruction carrying the device storage location to the target warning device, so that the target warning device flies to the device storage location through the aircraft component.

[0142] Specifically, after a target traffic event occurs, when the traffic event warning platform receives a traffic event warning request, it controls the warning device to fly to the location where the target traffic event occurs to warn the target traffic event. When the target traffic event is eliminated and traffic warning is no longer required, it is necessary to timely retrieve the warning device parked here, that is, send a warning cancellation request for the target traffic event to the traffic event warning platform.

[0143] Among them, the warning cancellation request can be sent by the traffic management department to the traffic event warning platform through a dedicated system after the traffic event is processed and the road resumes normal traffic; it can also be reported by on-site staff using a mobile terminal after confirming that the traffic event has been properly resolved, or it can be triggered by the traffic event warning platform when it analyzes from the image information fed back by the warning device that the target traffic event no longer exists.

[0144] Once the traffic event warning platform receives the warning cancellation request, it will determine the device storage location of each warning device. The device storage location is determined according to the distribution of surrounding device storage sites, the current location of the warning device, battery life, etc., so as to facilitate the centralized management and reallocation of the devices, and reduce the time and energy consumption required for the devices to return.

[0145] After determining the device storage location, a second flight control instruction carrying the device storage location is sent to the target warning device, so that the target warning device flies to the device storage location through the aircraft component.

[0146] In the above implementation of the present application, by sending a second flight control instruction to the target warning device to make it fly to the device storage location, the automatic recovery of the warning device is realized, the recovery efficiency of the warning device is improved. At the same time, by enabling the device to return to the reserve state as soon as possible, it is conducive to the centralized management and maintenance of the device and can also respond to the next traffic event at any time.

[0147] As Figure 3 shown, it is a schematic structural diagram of a traffic event warning system. The traffic event warning system includes a warning device and a traffic event warning platform. Among them, the number of warning devices can be multiple, and the traffic event warning platform is wirelessly connected to the warning device. Among them, the warning device at least includes a main control board, a communication module, a positioning module, a sensing module, a warning module, a gigabit switch function module, and an aircraft.

[0148] The main control board is connected to the communication module through an m.2 or other physical interface. The communication module can be a 4G / 5G communication module. The communication module is used to realize data interaction between the warning device and the traffic event warning platform, such as transmitting real-time location information and image information, etc., and receiving various control instructions, such as flight control instructions. The main control board is connected to the positioning module through a serial port or other physical interface. The positioning module can be a positioning system that integrates GPS and Beidou satellite positioning technologies. With the dual positioning functions of the GPS and Beidou satellite navigation systems, the warning device can accurately obtain its own geographical location information, providing an accurate coordinate basis for flight path planning, determination of the target parking position, and positioning of the traffic event site. The main control module is also connected to the sensing module through a USB or other physical interface. The sensing module includes a camera and a radar, which are used to photograph the scene of the traffic event and monitor the driving conditions of vehicles around the warning device. The main control board is also connected to the warning module through a serial port or other physical interface. The warning module can be a speaker and a warning light.

[0149] In addition, the main control board is also connected to the gigabit switch function module, which can realize high-speed data exchange and sharing among multiple warning devices, improving the data processing efficiency of the entire warning device system. For example, in a scenario where multiple warning devices work together, through the gigabit switch function, each warning device can quickly share traffic event information, device status information, etc., to realize more efficient collaborative warning and obstacle avoidance and other functions.

[0150] The main control board is also connected to the aircraft through a USB-C physical interface. When the main control board receives the first flight control instruction, it can send the target parking position carried therein to the aircraft, so as to realize reaching the occurrence point of the target traffic event through the aircraft. And when the main control board receives the second flight control instruction, it can send the device storage position carried therein to the aircraft, so as to realize reaching the device storage position through the aircraft.

[0196] For the traffic incident warning device provided by this application, after receiving a traffic incident warning request, the traffic incident warning platform first determines the target warning devices for warning the target traffic incident according to the traffic incident information, and then sends a first flight control instruction to each target warning device, so that each target warning device can fly to the location where the target traffic incident occurs within a short time by means of an aircraft component that is not restricted by terrain and traffic conditions. Thus, it can quickly intercept, divert and warn passing vehicles after the target traffic incident occurs, improving the traffic incident warning efficiency and avoiding traffic accidents. At the same time, by controlling the warning to reach the location of the target traffic incident in a flying manner, the need for manual warning at the accident scene is reduced, and the labor cost and the risk of personnel working in a dangerous environment are lowered.
