[0024] Embodiment 1

[0025] Figure 1 This is a flowchart of a method for controlling a highway warning sign provided by an embodiment of the present invention. This embodiment can be applied to the situation where, after a patrol vehicle reaches a designated location, a warning sign is released and automatically controlled to be placed at a designated location based on the distance information collected. This method can be executed by a control device for a highway warning sign. The control device for a highway warning sign can be implemented in the form of hardware and / or software, and the control device for a highway warning sign can be configured in an electronic device. Figure 1 As shown, the method includes:

[0026] S110 . In response to a warning sign release instruction, control the target highway warning sign to be detached from the highway patrol vehicle.

[0027] The warning sign release instruction may be an instruction for instructing a sign storage compartment provided on a highway patrol vehicle to release the warning sign. The target highway warning sign may be a warning sign that matches the highway patrol vehicle.

[0028] Specifically, when a warning sign release command is received, the target highway warning sign is controlled to be detached from the highway patrol vehicle, for example, the target highway warning sign may be installed in a sign storage compartment at the rear of the highway patrol vehicle, and then when a warning sign release command is detected, the target highway warning sign is released to the outside of the highway patrol vehicle through a hydraulic rod provided in the sign storage compartment. It should be noted that the operation and maintenance personnel in the highway patrol vehicle can send a warning sign release command through a control device pre-installed in the vehicle, and the control device may be a control handle that matches the target highway warning sign.

[0029] S120, obtaining distance information between the target highway warning sign and a road identification object, and controlling the target highway warning sign to move to a target position according to the distance information and a preset driving speed.

[0030] The road identifier may be an object used to identify the road boundary, and the road identifier may include a highway guardrail and a lane dividing line. The preset driving speed may be a driving speed of a pre-set highway warning sign. The target position may be a placement position that matches the highway warning sign.

[0031] Specifically, the required sensors are installed on the target highway warning sign and calibrated to ensure measurement accuracy. In addition, a reasonable preset driving speed is pre-set based on road and traffic conditions. The sensor is then used to measure the distance between the target highway warning sign and the road identification object in real time. Based on the measured distance information and the preset driving speed, a speed control algorithm is run to calculate and adjust the moving speed. The target highway warning sign is driven by an actuator to move to the target position at the calculated speed.

[0032] On the basis of the above technical solution, the control of moving the target highway warning sign to the target position according to the distance information and the preset driving speed includes: controlling a vehicle-mounted drone to connect with the target highway warning sign; after detecting that the connection between the vehicle-mounted drone and the target highway warning sign is completed, controlling the vehicle-mounted drone to transport the target highway warning sign to the target position at a preset driving speed.

[0033] Among them, the vehicle-mounted drone can be a drone installed on a highway patrol vehicle.

[0034] Specifically, when it is detected that the target highway warning sign needs to be moved to the target position, the vehicle-mounted drone can be controlled to connect with the target highway warning sign. After detecting that the connection is completed, the vehicle-mounted drone can send a connection completion signal. After detecting the connection completion signal, the vehicle-mounted drone can be controlled to carry the target highway warning sign to the target position according to the preset driving speed. It can be understood that in the process of moving the target highway warning sign by the vehicle-mounted drone, the target highway warning sign can perform warning work, for example, the tripod is controlled to be powered on and send a sound warning message, so that road warnings can also be performed during transportation. Exemplarily, a drone can also be deployed on a highway patrol vehicle, and the drone can be connected to the highway warning sign by magnetic suction. Accordingly, a magnetic suction device, such as an electromagnetic suction cup, can be deployed at the bottom of the drone and the top of the highway warning sign. When the traffic situation on the highway is more complicated, the drone can be controlled by a remote control device to magnetically connect with the highway warning sign, and then the drone is controlled to carry the highway warning sign to the target position.

[0035] It should be noted that the technical solution provided in the embodiment of the present invention provides two solutions for moving the target highway warning sign to the target position. When the road conditions on the current highway section are not complicated, the target highway warning sign can be released automatically, and the information collected by the warning sign is automatically moved to the target position; when the road conditions on the current highway section are relatively complicated, for example, there is a traffic accident, a road landslide or excessive traffic, the vehicle-mounted drone is controlled to connect with the target highway warning sign, and the vehicle-mounted drone is controlled to transport the target highway warning sign to the target position.

[0036] On the basis of the above technical solution, the distance information between the target highway warning and the road identifier is obtained, including: acquiring a road image corresponding to the target road by an image acquisition device arranged in the target highway warning sign; determining the road identifier corresponding to the target road based on the road image, and determining the distance information between the target highway warning sign and the road identifier according to the road identifier.

[0037] The image acquisition device may be a sensor for acquiring image information, such as a binocular camera, etc. The target road may be a high-speed lane for high-speed patrol vehicles or a high-speed emergency lane.

[0038] Specifically, a high-resolution camera or image sensor is installed in the target highway warning sign to capture the road image ahead, and then the collected road image is preprocessed, which may include denoising, contrast enhancement, distortion correction, etc., and image processing algorithms, such as edge detection, color segmentation, texture analysis, etc., are used to extract the features of road identifiers, and based on the extracted features, machine learning or deep learning algorithms are used to identify road identifiers, such as highway guardrails and lane dividing lines, and then the distance information between the target highway warning sign and the road identifier is determined according to the road identifier.

[0039] Based on the above technical solution, determining the distance information between the target highway warning sign and the road identifier according to the road identifier includes: collecting the distance information between the target highway warning sign and the road identifier through a radar scanning device set in the target highway warning sign.

[0040] The radar scanning device may be a radar device used for ranging, such as a laser radar.

[0041] Specifically, the radar scanning device is installed in the target highway warning sign to ensure that it can clearly and unobstructedly scan the road identification object. The radar scanning device emits radar waves and receives echoes reflected by the road identification object. By processing the echo signal, the distance information between the target highway warning sign and the road identification object can be obtained. According to the measured distance information and the preset driving speed, the moving speed of the target highway warning sign is adjusted to ensure that it maintains a safe distance from the road identification object. Exemplarily, in the process of determining the distance information between the target highway warning sign and the road identification object, the collected radar data can be filtered to remove noise and interference signals, improve measurement accuracy, and calculate the actual distance between the target highway warning sign and the road identification object based on the propagation time of the radar wave and the speed of light.

[0042] On the basis of the above technical solution, after controlling the target highway warning sign to move to the target position according to the distance information and the preset driving speed, it also includes: when a collision is detected with the target highway warning sign, generating collision warning information, and sending the collision warning information to the warning device, so that the warning device gives a prompt according to the collision warning information.

[0043] The collision warning information may be a warning information for reminding the operation and maintenance personnel that a vehicle collision has occurred. The warning device may be understood as a device for sending warning information to the operation and maintenance personnel.

[0044] Specifically, an impact sensor, such as an acceleration sensor, a pressure sensor or a vibration sensor, is installed on the target highway warning sign to detect an impact event. When an impact event is detected, an impact warning message is generated. The impact warning message may include detailed information such as the impact time, impact force, and impact position. The impact warning message is sent to the warning device via wireless communication, and the warning device then gives a prompt based on the impact warning message.

[0045] On the basis of the above technical solution, the warning device provides a prompt according to the collision warning information, including: when the warning device is a voice prompt device of the highway patrol vehicle, generating voice prompt information corresponding to the collision warning information; and / or, when the warning device is a wearable prompt device, generating vibration prompt information corresponding to the collision warning information.

[0046] The voice prompt device can be understood as a device for providing voice prompts. The wearable prompt device can be a prompt device worn by operation and maintenance personnel.

[0047] Specifically, when the warning device is a voice prompt device installed on a highway patrol vehicle, corresponding voice prompt information is automatically generated according to the collision warning information and played through the vehicle's audio system to alert the driver or other people in the vehicle. When the warning device is a wearable prompt device (such as a smart watch, smart bracelet, etc.), corresponding vibration prompt information is generated according to the collision warning information and transmitted to the wearer through the device's vibration motor to attract his or her attention.

[0048] Exemplarily, when the warning device is a voice prompt device installed on a highway patrol vehicle, the voice prompt device receives the collision warning information from the target highway warning sign through wireless communication, and the built-in processor of the device parses the received collision warning information, extracts key information (such as collision time, collision location, collision force, etc.), and converts it into a text format suitable for voice playback, and uses speech synthesis technology (such as TTS, Text-to-Speech) to convert the text format collision warning information into a voice signal, and plays the generated voice prompt information through the vehicle's sound system to remind the operation and maintenance personnel to pay attention to the collision event and take corresponding measures. When the warning device is a wearable prompt device, the wearable prompt device receives the collision warning information from the target highway warning sign through wireless communication (such as Bluetooth, Wi-Fi, etc.), and the built-in processor of the device parses the received collision warning information, and determines whether it is necessary to generate vibration prompt information according to a preset rule or algorithm. If it is necessary to generate vibration prompt information, the vibration motor of the control device is vibrated according to a specific mode (such as continuous vibration, intermittent vibration, vibration of different frequencies, etc.) to remind the wearer to pay attention to the collision event.

[0049] On the basis of the above technical solution, after controlling the target highway warning sign to move to the target position according to the distance information and the preset driving speed, it also includes: upon receiving a high-speed operation completion instruction, controlling the target highway warning sign to return to the highway patrol vehicle.

[0050] Among them, the high-speed operation completion instruction can be a control instruction for instructing the high-speed warning sign to return automatically.

[0051] Specifically, the high-speed operation completion instruction can be issued by the driver of the high-speed patrol vehicle through the in-vehicle control system or through a remote control device. After receiving the high-speed operation completion instruction, the current position of the target high-speed warning sign is confirmed to ensure that the warning sign is in a recyclable state, and the battery power, communication status, mechanical structure, etc. of the target high-speed warning sign are checked to see if they are normal. According to the current position of the target high-speed warning sign and the position of the high-speed patrol vehicle, the optimal return path is planned, and then the moving speed of the target high-speed warning sign is adjusted according to the length of the return path, the road conditions, and the speed of the high-speed patrol vehicle. The navigation system on the target high-speed warning sign is used to move according to the planned return path. When the target high-speed warning sign approaches the high-speed patrol vehicle, the system should be prepared for docking, such as adjusting the receiving device on the vehicle, opening the corresponding hatch, etc., to control the target high-speed warning sign to accurately dock with the designated position on the high-speed patrol vehicle. For example, the high-speed warning sign can be stored in the equipment storage bin by magnetic attraction.

[0052] On the basis of the above technical solution, before controlling the target highway warning sign to move to the target position according to the distance information and the preset driving speed, it includes: obtaining current weather information, and determining the target position corresponding to the target highway warning sign according to the current weather information.

[0053] Among them, the current weather information can be understood as the weather data of the current patrol section.

[0054] Specifically, the current weather information is obtained in real time from professional weather forecast service agencies or meteorological stations, including key data such as temperature, humidity, wind speed, wind direction, precipitation and visibility, and then the target position corresponding to the current weather information is determined based on the weather information. For example, on the highway, a warning sign should be set 150 meters behind the vehicle. If it encounters rainy and foggy weather, the setting distance of the warning sign needs to be increased to 200 meters; on urban roads, the warning sign should be placed 50 meters behind the vehicle; if it is at night, the placement distance of the warning sign should be extended to 150 meters; on the highway, the warning sign should be placed 150 meters behind the vehicle; at night, the placement distance of the warning sign should be extended to 250 meters. The placement of the warning sign can be specifically set in accordance with the requirements of the above road safety regulations to ensure safety.

[0055] The technical solution of the embodiment of the present invention controls the target highway warning sign to detach from the highway patrol vehicle in response to the warning sign release instruction, thereby obtaining the distance information between the target highway warning sign and the road identification object, and controls the target highway warning sign to move to the target position according to the distance information and the preset driving speed, wherein the road identification object includes the highway guardrail and the lane dividing line. Based on the above technical solution, the highway warning sign is automatically controlled according to the collected distance information, and the highway warning sign is automatically placed, which reduces the danger of patrol personnel placing warning signs and improves the efficiency and standardization of placing warning signs.
