[0015] At the same time, the sign vehicle adopts the form of unmanned driving, which minimizes the serious consequences caused by the rear-end collision of the social vehicle with the sign vehicle or the maintenance vehicle and ensures the safety of life and property.

[0016] The sign vehicle includes a vehicle body 1. Specifically, the vehicle body 1 is an existing technology. The vehicle body 1 adopts a miniaturized structure, which has a relatively small blocking effect on social vehicles in the event of a collision, thus reducing the impact on injuries in social vehicles and at the same time effectively reducing the severity of injuries suffered by vehicle occupants due to collisions.

[0017] Specifically, the vehicle body 1 is provided with an electric drive module, realizes the drive of the running part 2, realizes the march of the sign vehicle in the form of an electric drive, and can ensure that the sign vehicle has sufficient power and reaction speed at the same time.

[0018] The bottom of the sign vehicle 1 is provided with a walking part 2, in particular, the walking part 2 realizes the walking control of the sign vehicle, and in the present embodiment, the walking part 2 also includes a direction system, a braking system, and can realize the control of the walking direction and braking of the sign vehicle.

[0019] A control unit 3 is installed in the vehicle body 1. The control unit 3 can receive and process the signals transmitted by the distance sensor 4, the camera 6, the warning light 7, and the collision sensor 8. At the same time, it can also control the running unit 2 and the warning unit. The warning light 7 and the alarm 9 are controlled, and warnings and other information can also be displayed on the electronic display screen 5.

[0020] In addition, the control unit 3 has an integrated positioning module and a wireless communication module. The wireless communication module includes cellular, GPS, WIFI, millimeter wave, and terahertz communication subsystems to realize signal interaction with base stations, satellites, routing, other peripherals, or sensors.

[0021] The front end of the vehicle body 1 is equipped with a distance sensor 4. Specifically, the distance sensor 4 is installed in the center of the front end of the vehicle body 1 to monitor the distance between the sign vehicle and the maintenance vehicle in front. The monitoring data is transmitted to the control part 3 in real time for processing. At the same time, the control part 3 transmits the detection data to the intelligent control center via the wireless communication module. The intelligent control center then collects and analyzes the dynamic distance data between the sign vehicle and the maintenance vehicle and realizes intelligent control of the running direction and speed of the sign vehicle. The sign vehicle is designed to move synchronously and automatically at a set distance behind the maintenance vehicle.

[0022] The upper front part of the vehicle body 1 is permanently equipped with an electronic display screen 5, which can display a variety of traffic signs and information depending on the situation. In particular, the electronic display screen 5 can display warning texts, warning symbols, obstacle locations, prohibited sections, and dynamic electronic displays.In actual use, the setting of display information can be performed by an intelligent control center, and the display of relevant warning is realized through the electronic display screen 5 by the control part 3, so as to notify the driver passing through this road section, make an accurate prediction of the road environment in advance, change lanes in time to avoid the longitudinal operation section formed by maintenance work, actively avoid risks, ensure the safety of vehicle traffic and the safety of maintenance operation.

[0023] The described electronic display screen 5 is equipped with the camera 6, forms a video monitoring for the rear social vehicle, and transmits a real-time monitoring image to the intelligent control center through the control part 3, realizes effective monitoring of the driving state of the rear vehicle, and provides real information for traceability work after an emergency occurs.

[0024] A warning lamp 7 and a collision sensor 8 are provided at the rear end of the vehicle body 1. Specifically, the collision sensor 8 is located in the center of the rear end of the vehicle body 1, and the warning lamps 7 are illuminated on both sides of the collision sensor 8.

[0025] During implementation, once a social vehicle collides with or encounters the sign vehicle, the collision sensor 8 detects the collision signal and transmits the collision signal to the control part 3. The control part 3 drives the warning light 7 and the alarm 9. The light alarm warning prompts other vehicle drivers to actively avoid the traffic. At the same time, the control part 3 transmits the collision signal to the intelligent control center, and the intelligent control center synchronously transmits the collision information to the operating vehicle to facilitate timely emergency response.

[0026] In concrete terms, the configuration of camera 6 and collision sensor 8 provides a dual safety guarantee. At the same time, the surroundings can be monitored in real time and emergency situations can be responded to quickly.

[0027] An alarm 9 is provided at the upper end of the vehicle body 1. The alarm 9 can trigger an audible alarm when a collision occurs, or it can trigger an automatic alarm depending on the actual situation.

[0028] The running part 2, the distance meter 4, the electronic display screen 5, the camera 6, the warning light 7, the collision sensor 8 and the alarm 9 are all electrically connected to the control part.

[0029] It also includes an intelligent control center and the intelligent control center is connected to the control module via a communication module.

[0030] In a concrete implementation, the intelligent control center can also receive the real-time position information of the maintenance vehicle and process it simultaneously by receiving and processing the real-time position of the sign vehicle and the monitoring data of the distance meter 4, and transmitting the processing results to the control part 3. It can be realized that the sign vehicle can acquire the position information of the mobile maintenance vehicle in real time and then realize automatic control of the steering, speed, and braking of the sign vehicle through the control unit 3.

[0031] During the specific implementation, the utility model collects and analyzes the dynamic distance data between the sign vehicle and the maintenance vehicle using the real-time signal transmitted from the distance sensor 4 via the intelligent control center. This enables intelligent control of the running direction and speed of the sign vehicle. This allows the sign vehicle to move safely and reliably behind the maintenance vehicle at a specified distance.

[0032] During the driving of a sign vehicle, this sign vehicle can be arranged on the electronic display screen 5, the warning lamp 7 and the alarm 9 on the vehicle body 1 in the form of warnings such as sound and light, safety color, distance notification, prompting the driver of the rear vehicle to change lanes in time to avoid the longitudinal operation section formed by maintenance work, actively avoid risks, and ensure the safety of vehicle traffic and the safety of maintenance operation. Especially in special road sections such as continuous curves and long descents, as well as when visibility is affected by adverse factors such as fog and darkness, it can play a very important early warning effect, reminding the driver to predict the road environment conditions in time, actively avoid risks, and ensure the safety of road operation.

[0033] At the same time, the collision sensor 8 detects the collision signal via the collision sensor 8 provided on the vehicle body 1 and transmits the collision signal to the control unit 3 when a social vehicle approaches or collides with the sign vehicle. The control unit 3 is controlled so that the warning light 7 and the alarm 9 emit audible and visual alarms to prompt other vehicle drivers to take the initiative to avoid the collision. At the same time, the control unit 3 transmits the collision signal to the intelligent control center, and the intelligent control center synchronously transmits the collision information to the emergency vehicles for timely emergency response.

[0034] With the setting of camera 6, the driving state of the vehicle and the change of the environment during the entire process of recording the operating process form the basis for post-event analysis and forensics.

[0035] In addition, the integration of sound and light warning, collision warning, video surveillance and other safety protection measures forms a multimodal safety protection system, which can greatly improve emergency response capability.

[0036] The utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited to it. In short, if a person of ordinary skill in the art can be inspired by it and, without deviating from the creative purpose of the utility model, can design a structural method and embodiment similar to the technical solution without creativity, they all fall under the protection of the utility model.
