Attached Figure Description

[0015] Figure 1 This is a schematic diagram of a cone control method for highway sections proposed in this invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] A method for controlling traffic cones on highways includes: S1, obtaining road control requirements based on an aircraft; S2, setting a control plan based on the road control requirements and current area parameters; and S3, obtaining control authority to control the corresponding intelligent traffic cone unit and execute the control plan.

[0018] Highways are sections of road with speed limits, and these limits are often higher than a certain threshold, typically with a minimum speed limit of 80 km / h. Existing traffic control schemes use dedicated control vehicles, but these vehicles have several unresolved issues, such as high daily patrol costs, road resource occupation, and slow response times. Aircraft, especially drones, can overcome these problems. First, they do not occupy road resources; second, in case of emergencies, they can bypass highways and take shortcuts directly to their destination, resulting in faster response times; third, as high-altitude mobile objects, they are less susceptible to communication interference, which is crucial for timely traffic control. Traffic control requirements include determining whether control is necessary and how to implement it. This can be determined by the aircraft itself after data collection or by responding to external commands.

[0019] Road control requirements describe the general control needs, while current area parameters are the actual relevant data on site. Combining these two, control plans can be set up to propose specific control plans for the specific site. With control plans, standardized operations can be carried out to avoid errors, and step-by-step operations can be facilitated to ensure the entire operation is orderly and meets the requirements for automated and unmanned operations.

[0020] The aircraft can carry intelligent cone units and then drop them by air or land. However, in general, the intelligent cone units that are already on the ground are used, because this reduces the burden on the aircraft and keeps the aircraft's size and cost low. In this case, the management systems of the aircraft and the cone are different, and control authority needs to be obtained before the aircraft can control the cone and execute the control plan.

[0021] The method of obtaining road control requirements based on aircraft includes: setting up an aircraft and driving the aircraft to patrol along the highway section; and using the radar and / or camera devices of the aircraft to identify targets on the highway section in order to determine whether road control should be implemented.

[0022] In the absence of accidents, deploying aircraft to patrol highways can reduce the time it takes for the aircraft to reach the scene in the event of an accident, allowing more time for traffic control and thus helping to reduce the probability of secondary / chain accidents. The aircraft is equipped with radar and / or cameras to acquire images of the highway, which are then processed. This processing can be done either by the aircraft's own data processing unit or by transmitting the images to the cloud for processing and then returning them to the aircraft. If smoke, flames, or two targets are too close together (i.e., a collision) are observed on the highway, road control is deemed necessary.

[0023] In extremely rare circumstances, even without any apparent anomalies, control measures may be necessary, such as road maintenance or special transportation missions requiring control. In such cases, aircraft can be instructed to perform control tasks. Through specific physical drills, numerous abnormal image samples can be designed to train image or video recognition models. These models can then be used to determine whether road control measures should be implemented.

[0024] The step of identifying targets on the highway segment to determine whether road control should be implemented includes: identifying targets on the highway segment to determine fixed targets and moving targets on the segment, calculating the movement parameters of the moving targets or identifying the corresponding stop coordinate parameters; the aircraft determining whether road control is required based on the movement parameters and the stop coordinate parameters; or, the aircraft transmitting the movement parameters and the stop coordinate parameters to a remote management terminal for judgment, and determining whether road control should be implemented based on the feedback result; or acquiring an image of the current controlled area, analyzing it to determine whether to end road control, or acquiring an instruction input from the remote management terminal to end road control.

[0025] Fixed targets along a road segment include various elements of the road itself, such as guardrails / railings, road signs, traffic markings, various debris, ancillary facilities, service areas, etc. These elements are standardized and are targets of daily patrols, making it easy to acquire / generate training templates, thus training the recognition model is relatively easy, the recognition process is simple, and the accuracy is high. Moving targets are non-fixed targets along the road segment, including various targets moving on the road, mainly vehicles and pedestrians (although walking on highways is prohibited, it still happens in practice, such as villagers crossing or people getting out of vehicles, so it must also be considered). The movement parameters of these moving targets are calculated; any abnormal movement parameters, such as moving too fast or too slow, require attention. If a moving target that should be moving stops, its corresponding stopping coordinate parameters need to be identified. For example, stopping in a non-emergency area could lead to a collision with subsequent vehicles. If such a situation occurs, road control measures are required.

[0026] If the aircraft's data processing capabilities are insufficient, data can be uploaded to a remote management terminal for assessment, and the decision on whether to implement road control can be made based on the feedback results. In this case, the remote management terminal has higher processing capabilities and can access various databases, resulting in a better assessment of whether on-site control is necessary.

[0027] Sometimes, when unusual or abnormal events occur, relying solely on movement or stop coordinate parameters may not be sufficient for accurate judgment. In such cases, it is necessary to acquire images of the current controlled area and analyze them to determine whether to end or resume road control. If the algorithm for handling flying objects cannot process them, images must be uploaded to a remote management terminal for judgment, such as when tracking specific targets like suspects.

[0028] Sometimes, the remote management terminal directly receives the input instructions to end road control, for example, when personnel are already on site controlling the traffic and instruct the aircraft to leave.

[0029] The road control requirements include control type and legal authentication information. The current area parameters include geographic coordinates, equipment status information, and real-time on-site information. Correspondingly, the setting of the control plan includes: determining the required equipment type and quantity based on the control type and the real-time on-site information, and outputting equipment deployment parameters; determining the required equipment type and quantity based on the control type and the real-time on-site information, and establishing a control chain to drive the corresponding specialized equipment in conjunction with the equipment status information and the legal authentication information; outputting warning information to at least one of the remote management terminal, the on-site emergency communication device, and mobile units on the current road segment based on the control type and the geographic coordinates; determining a loitering flight plan based on the geographic coordinates and the real-time on-site information, combined with the aircraft's flight parameters and the control type; and establishing a data transmission chain with the remote management terminal based on the legal authentication information to transmit the real-time on-site information and obtain control commands.

[0030] Control types can include restricted passage, prohibited passage, traffic diversion, etc. Geographic coordinates can be satellite positioning data or local geographic coordinate data. Equipment status information includes equipment type, quantity, storage location, etc. Real-time on-site information refers to various data collected on-site.

[0031] The specialized equipment includes the intelligent cone unit and / or a device for deploying the intelligent cone unit. The real-time on-site information includes road background information and controlled object information. Correspondingly, determining the required equipment type and quantity based on the control type and the real-time on-site information, and outputting equipment deployment parameters, includes: determining image processing parameters based on the control type; dividing the area to be processed and the passage area based on the image processing parameters from the road background information and the controlled object information; determining the number of intelligent cone units based on the area and location parameters of the area to be processed and the passage area; identifying a specific target as a moving reference point based on the road background information and the controlled object information, and calculating the equipment deployment parameters.

[0032] The type of traffic control involves different elements, such as vehicles, personnel, and barriers. Different elements require different levels of accuracy in identification. Therefore, image processing parameters are determined based on the control type. Different algorithms can be selected based on these parameters to improve identification accuracy, and the subsequent control algorithms may also differ. The principle of dividing the area into processing zones and passage zones basically includes preventing other vehicles or personnel from approaching the accident vehicle. Specifically, the processing zone can be defined as a distance of 1 / 2 meters from the accident vehicle, while the passable roads outside this distance constitute the passage zone. Highways have a high degree of design similarity, so the specific identification difficulty is not high; even the processing capabilities of aircraft are sometimes sufficient. Based on area and location parameters, a formula can be set, such as determining the number of cones for a large area, or reducing the number of cones if there are many vehicles to facilitate passage for other vehicles.

[0033] Based on the control type and the real-time on-site information, the required equipment types and quantities are determined, and equipment deployment parameters are output. Specifically, the required equipment types and quantities can be determined based on the area of ​​the accident site, the number of targets, etc., and then the equipment deployment parameters are output based on the existing planning and design. Specific targets are mainly accident vehicles. Sometimes, if they are inconvenient to identify (e.g., vehicles are severely deformed or burned), they can be railings or other objects with obvious characteristics, such as trees outside the road, roadside lamps, overpasses, etc.

[0034] The equipment status information includes the types, quantities, storage locations, and manager information of the existing backup equipment in the current area; correspondingly, the manager information is determined based on the types, quantities, storage locations, and equipment layout parameters; based on the legitimate authentication information, a control chain is established through the manager information to drive the corresponding backup equipment.

[0035] Some equipment cannot be directly accessed but requires an application for access. Specifically, by combining the equipment status information and the legal authentication information, a control chain is established to drive the corresponding specialized equipment. The control chain includes obtaining permissions, data channels, passwords, etc. from the equipment administrator and establishing a communication connection with the specialized equipment to drive it.

[0036] The remote management terminal includes the responsible department, and the corresponding warning information includes vehicle information, personnel information, accident type, geographical coordinates, and real-time on-site data; the on-site emergency communication device includes the existing on-site communication equipment on the highway section, and the corresponding data format is determined based on the model of the on-site communication equipment to generate the warning information; the mobile units on the current road section include motor vehicles, personnel, and unmanned vehicles, and the corresponding warning information includes the accident location, accident type, and detour prompts.

[0037] Some highways are equipped with communication devices, such as communication antennas, to handle emergencies. These devices may not have intelligent interactive functions and require specific data formats to enable normal communication.

[0038] The step of determining a loitering flight plan based on the geographic coordinates and the real-time on-site information, combined with the aircraft's flight parameters and the control type, includes: scanning the surrounding environment based on the geographic coordinates to determine a safe airspace range; identifying target graphic features based on the real-time on-site information, and determining key features from the target graphic features according to the control type; controlling the aircraft to approach the key features, or reducing the aircraft's speed to delay the time spent loitering in a designated area, or controlling the aircraft to fly cyclically within a designated area.

[0039] To avoid collisions with large trees, buildings, mountains, and similar structures, aircraft need to scan their surroundings using radar or cameras to determine a safe airspace. Specifically, this involves identifying objects and determining whether it's safe to fly. Targets are typically accident vehicles, with key features including the vehicle body and personnel. Since radar or cameras sometimes require a certain distance to obtain accurate data, the aircraft is controlled to approach these key features, or its speed is reduced to delay / increase its time at a designated area, or it is controlled to circulate within a designated area. If the control type is rescue, the target is people, with the key feature being the human body. If the control type is fire, the target is vehicles, with key features including flames or smoke.
