Description

A new type of mobile maintenance operation vehicle Technical Field

[0001] This invention relates to the field of highway maintenance equipment technology, specifically to a new type of mobile maintenance operation vehicle. Background Technology

[0002] With the increasing density and complexity of transportation networks, the safety of road maintenance work has become an issue that cannot be ignored. According to current highway maintenance safety operation regulations, highway maintenance operations are divided into long-term maintenance operations, short-term maintenance operations, temporary maintenance operations, and mobile maintenance operations. Among these, mobile marker vehicles can be used when setting up the maintenance operation control zone for temporary and mobile maintenance operations.

[0003] Currently, all mobile marker vehicles are manned motor vehicles, which have many limitations in reminding and protecting maintenance vehicles. According to regulations, their body color should be yellow, with a yellow warning light on the top and a yellow or orange flashing arrow on the rear. In routine highway maintenance, continuous mobile maintenance operations such as watering greenery and sweeping roads require vehicles (or equipment) to travel at low speeds and occupy driving lanes. The continuous longitudinal nature of these operations also necessitates sustained lane occupancy. Uncontrollable factors such as speeding, fatigued driving, driver inattention, continuous curves, and external influences (e.g., rain, fog, or changes in lighting) coupled with the significant speed difference between vehicles and mobile maintenance vehicles (or equipment) lead to frequent traffic accidents involving rear-end collisions with marker vehicles or impacts with mobile maintenance vehicles (such as water trucks and sweepers), resulting in injuries and vehicle damage.

[0004] Therefore, a new type of mobile maintenance operation vehicle is proposed to address the current shortcomings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide a new type of mobile maintenance operation marking vehicle.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is a novel mobile maintenance operation marking vehicle: including a vehicle body;

[0007] The vehicle body has a walking section at the bottom, a control section built into the vehicle body, a rangefinder at the front of the vehicle body, an electronic display screen fixedly mounted on the upper front of the vehicle body, a camera mounted on the electronic display screen, a warning light and a collision sensor at the rear of the vehicle body, and an alarm at the upper rear of the vehicle body.

[0008] The walking unit, rangefinder, electronic display screen, camera, warning light, collision sensor, and alarm are all electrically connected to the control unit.

[0009] As an improvement, the control unit incorporates a positioning module and a wireless communication module.

[0010] As an improvement, an intelligent control center is also included, which is connected to the control module via a communication module.

[0011] As an improvement, the wireless communication module includes cellular, GPS, WIFI, millimeter wave, and terahertz communication subsystems to enable signal interaction with base stations, satellites, routers, other peripherals, or sensors.

[0012] As an improvement, the electronic display screen is capable of displaying warning text, warning symbols, obstacle locations, restricted road sections, and dynamic directions of travel.

[0013] As an improvement, the collision sensor is located in the middle of the rear end of the vehicle body, and the warning lights are located on both sides of the collision sensor.

[0014] The advantages of this invention compared to the prior art are:

[0015] 1. It can reduce the number of drivers for the signage vehicle, lower labor costs, and eliminate the safety risks associated with the signage vehicle driver;

[0016] 2. The vehicle is electrically driven, small in size, light in weight, and has a low center of gravity. In the event of a collision, it has a relatively small effect on preventing damage to other vehicles, thus reducing the damage to other vehicles and effectively reducing the severity of injuries to the occupants of the vehicle due to the collision.

[0017] 3. In areas with poor visibility, distance warning information is set on the sign vehicle to inform drivers traveling through the area to make accurate predictions about the road conditions in advance and change lanes in time to avoid risks;

[0018] 4. The collision sensors can be set up to form an early warning system. When the vehicle is involved in a collision or rear-end collision, it will issue an audible and visual warning signal to remind the driver and on-site personnel to take timely countermeasures.

[0019] 5. The cameras installed on the signage vehicle can form a video surveillance system, which can effectively monitor the driving status of vehicles behind and provide real information for the tracing work after an emergency occurs;

[0020] 6. This sign vehicle can be used in conjunction with work vehicles, and through various warning methods such as sound and light, safety colors, and distance indications, it enables vehicles to proactively avoid risks, ensuring traffic safety and maintenance work safety. Furthermore, the integration of collision sensors and cameras further enhances its safety. This sign vehicle operates autonomously, effectively reducing costs. Its compact structure also minimizes injury to vehicles and personnel in the event of a collision, significantly improving the safety of both work vehicles and maintenance vehicles.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the invention clearer, the technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] In the description of the embodiments of the invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0029] In the description of the embodiments of the invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the invention according to the specific circumstances.

[0030] As shown in Figures 1-3, a new type of mobile maintenance operation marker vehicle is designed to automatically follow maintenance vehicles while maintaining a safe distance. It also features highly intelligent control and safety protection functions to reduce the risk of traffic accidents and improve the efficiency and safety of road maintenance operations.

[0031] Meanwhile, the sign-on vehicle is driverless, minimizing the serious consequences of rear-ending collisions between other vehicles and the sign-on vehicle or maintenance vehicles, thus ensuring the safety of life and property.

[0032] The vehicle with the sign includes a vehicle body 1. Specifically, the vehicle body 1 is based on existing technology and adopts a miniaturized structure. In the event of a collision, the vehicle body 1 has a relatively small stopping effect on other vehicles, reducing the damage to other vehicles and effectively reducing the severity of injuries to the occupants due to the collision.

[0033] Specifically, the vehicle body 1 is equipped with an electric drive module to drive the walking unit 2, thereby enabling the sign vehicle to move in an electric drive manner, while ensuring that the sign vehicle has sufficient power and response speed.

[0034] The bottom of the vehicle body 1 is provided with a walking part 2. Specifically, the walking part 2 realizes the walking control of the sign vehicle. In this embodiment, the walking part 2 also includes a direction system and a braking system, which can realize the control of the walking direction and braking of the sign vehicle.

[0035] The vehicle body 1 has a built-in control unit 3. The control unit 3 can receive and process signals transmitted by the rangefinder 4, camera 6, warning light 7, and collision sensor 8. It can also control the walking unit 2, warning light 7, and alarm 9, and can display warning information through the electronic display screen 5.

[0036] Furthermore, the control unit 3 has a built-in 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, routers, other peripherals or sensors.

[0037] The vehicle body 1 is equipped with a distance measuring device 4 at its front end. Specifically, the distance measuring device 4 is located in the middle of the front end of the vehicle body 1. It is used to monitor the distance between the sign vehicle and the maintenance work vehicle in front, and transmit the monitoring data to the control unit 3 in real time for processing. At the same time, the control unit 3 transmits the detection data to the intelligent control center through a wireless transmission module. Then, the intelligent control center collects and analyzes the dynamic distance data between the sign vehicle and the maintenance work vehicle, so as to realize the intelligent control of the sign vehicle's walking direction and speed, and realize that the sign vehicle moves synchronously and autonomously behind the maintenance work vehicle at a set distance.

[0038] An electronic display screen 5 is fixedly installed on the upper front of the vehicle body 1. This screen can display various traffic signs and information depending on the situation. Specifically, the electronic display screen 5 can display warning text, warning symbols, obstacle locations, prohibited sections, and dynamic directions of travel. In actual use, the displayed information can be set through the intelligent control center, and the control unit 3 can display relevant warnings on the electronic display screen 5. This informs drivers traveling on the road section to make accurate predictions about the road environment in advance, change lanes in time to avoid longitudinal work sections caused by maintenance work, proactively avoid risks, and ensure vehicle traffic safety and maintenance work safety.

[0039] The electronic display screen 5 is equipped with a camera 6, which forms a video surveillance of vehicles behind. The real-time monitoring images are transmitted to the intelligent control center through the control unit 3, so as to effectively monitor the driving status of vehicles behind and provide real information for the traceability work after the occurrence of emergencies.

[0040] The rear end of the vehicle body 1 is equipped with a warning light 7 and a collision sensor 8. Specifically, the collision sensor 8 is located in the middle of the rear end of the vehicle body 1, and the warning light 7 is located on both sides of the collision sensor 8.

[0041] During implementation, once a social vehicle rear-ends or collides with the sign vehicle, the collision sensor 8 detects the collision signal and transmits the collision signal to the control unit 3. The control unit 3 controls the warning light 7 and the alarm 9 to issue an audible and visual alarm warning, prompting 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 transmits the collision information to the work vehicle in a timely manner so as to make an emergency response.

[0042] In practice, the setup of camera 6 and collision sensor 8 provides dual safety protection, while also allowing for real-time monitoring of the surrounding environment and rapid response in emergencies.

[0043] An alarm 9 is provided on the upper rear of the vehicle body 1 shown. The alarm 9 can provide an audible alarm when a collision occurs, or provide an automatic alarm according to the actual situation.

[0044] The walking unit 2, rangefinder 4, electronic display screen 5, camera 6, warning light 7, collision sensor 8, and alarm 9 are all electrically connected to the control unit 3.

[0045] It also includes an intelligent control center, which is connected to the control module through a communication module. The intelligent control center is responsible for collecting various data, analyzing them, issuing instructions, and coordinating the operation of the entire vehicle.

[0046] In practical implementation, the intelligent control center can also receive real-time location information of the maintenance vehicle. At the same time, by receiving the real-time location of the marker vehicle and the monitoring data from the rangefinder 4, it processes the data and transmits the processing results to the control unit 3. This enables the marker vehicle to perceive the location information of the moving maintenance vehicle in real time, and then the control unit 3 can automatically control the steering, speed, and braking of the marker vehicle.

[0047] In its specific implementation, this invention uses an intelligent control center to collect and analyze the dynamic distance data between the marker vehicle and the maintenance vehicle by transmitting real-time signals from the rangefinder 4. This enables intelligent control of the marker vehicle's direction and speed, allowing it to move synchronously and autonomously behind the maintenance vehicle at a set distance. This ensures that the marker vehicle can move safely and reliably behind the maintenance vehicle (or equipment) at a set distance.

[0048] During operation, the sign-equipped vehicle uses an electronic display screen 5, warning lights 7, and an alarm 9 mounted on the vehicle body 1 to provide warnings through sound and light, safety colors, and distance indications, prompting drivers of following vehicles to change lanes and avoid longitudinal work sections created by maintenance work. This proactively mitigates risks and ensures the safety of both vehicle traffic and maintenance operations. It is particularly effective in providing early warnings on challenging road sections such as continuous curves and long downhill slopes, as well as when visibility is affected by factors like heavy fog or overcast weather. This allows drivers to anticipate road conditions, proactively avoid risks, and ensure safe road operations.

[0049] Meanwhile, through the collision sensor 8 installed on the vehicle body 1, once a social vehicle rear-ends or collides with the sign vehicle, the collision sensor 8 detects the collision signal and transmits the collision signal to the control unit 3. The control unit 3 controls the warning light 7 and the alarm 9 to emit an audible and visual alarm warning, prompting 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 work vehicle so as to make timely emergency response.

[0050] Furthermore, in conjunction with the setup of camera 6, the vehicle's driving status and environmental changes throughout the entire operation are recorded, providing a basis for post-event analysis and evidence collection.

[0051] In addition, by integrating various safety protection measures such as sound and light warnings, collision warnings, and video surveillance, a multimodal safety protection system can be formed, which can significantly improve emergency response capabilities.

[0052] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
