Description

Technical Field

[0001] The utility model relates to the technical field of road surface detection, in particular to a three-dimensional road condition and road marking detection device in cold and high-altitude areas. Background Art

[0002] High-altitude and cold regions refer to those areas with extremely cold climates due to high altitude or latitude. These areas usually have the following notable characteristics:

[0003] 1. High Altitude

[0004] Definition: High-altitude and cold regions generally refer to areas with an average altitude of more than 3,000 meters, and some areas even have an altitude of more than 5,000 meters.

[0005] Impact: High altitudes mean thinner air, lower air pressure, and lower oxygen levels, which significantly impact both human function and mechanical equipment. For example, at altitudes above 4,000 meters, the oxygen content in the air is only about 60% of that in plains, significantly reducing human mobility and the efficiency of mechanical equipment.

[0006] 2. Low temperature all year round

[0007] Characteristics: High-altitude, cold regions experience lower temperatures due to their high altitude, resulting in a perennially low temperature climate. Generally speaking, the temperature drops by approximately 0.6 degrees Celsius for every 100 meters increase in altitude. Therefore, in high-altitude areas, the average annual temperature can be well below zero, with the lowest temperature reaching tens of degrees Celsius below zero.

[0008] Impact: Low temperatures pose a threat to human health, such as increasing metabolism, heightening sympathetic nerve tension, and reducing blood circulation, which can lead to frostbite and tissue cell peroxidation. Low temperatures can also affect the normal operation of mechanical equipment and the performance of materials.

[0009] 3. Frozen soil does not melt all year round

[0010] Phenomenon: In cold and high-altitude areas, due to extremely low temperatures, the moisture in the soil remains frozen year-round, forming permafrost. This deep and stable permafrost poses a challenge to engineering construction and geological exploration.

[0011] Impact: The presence of frozen soil reduces the bearing capacity of the foundation and deteriorates the stability of the project. It also affects the flow and distribution of groundwater. During engineering construction, special measures need to be taken to deal with frozen soil problems to ensure the safety and stability of the project.

[0012] Nowadays, it is necessary to inspect and evaluate road surfaces in cold and high-altitude areas, including:

[0013] 1. Highway technical condition inspection and evaluation

[0014] The inspection and evaluation of highway technical conditions encompasses four components: the road surface, roadbed, bridge and tunnel structures, and facilities along the route. Road surface inspection and evaluation indicators include pavement damage, flatness, and rutting. The overall development of road pavement inspection technology at home and abroad has evolved through three stages: from early traditional manual inspection to semi-automated inspection, and finally to the current non-destructive automatic inspection. Traditional manual and semi-automatic inspections present the following challenges: The working environment is harsh, the personal safety of inspectors cannot be guaranteed, and this impacts the normal operation of traffic; they are time-consuming, labor-intensive, and inefficient, making timely and periodic inspections difficult; and they are significantly affected by human factors, hindering the objective and accurate evaluation of road surface damage. With the rapid development of inspection technology and information technology, current non-destructive automatic inspections are gradually becoming mature and stable.

[0015] 2. Vehicle-mounted road marking retroreflection measurement

[0016] Road markings are the language of highways, signaling traffic information and serving as a crucial component of traffic control and guidance. Traditional road marking retroreflectivity testing equipment, using handheld road marking retroreflectivity testers, requires testing on open roads, requiring road closures and disrupting normal traffic flow. Vehicle-mounted road marking retroreflectivity meters are installed or integrated into vehicles and measure the retroreflectivity of road markings at normal driving speeds. This eliminates the labor-intensive, inefficient, and unsafe testing environment associated with traditional road marking retroreflectivity testers.

[0017] The existing technology for detecting three-dimensional road conditions and road markings in cold and high-altitude areas is relatively simple and cannot achieve the purpose of joint detection. It usually requires multiple devices to perform multiple inspections, which is inefficient. Utility Model Content

[0018] The purpose of the present invention is to provide a three-dimensional road condition and road marking detection device for cold and high-altitude areas to solve the problems raised in the above-mentioned background technology.

[0019] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a three-dimensional road condition and road marking detection device for high-altitude and cold areas, comprising a foldable lifting frame, a support column connected to the middle position of the interior of the foldable lifting frame, a square rod fixedly connected to the top of the support column, a moving rod extending from the inside of the square rod to the top thereof, an adjustment structure provided between the square rod and the moving rod, a connecting frame fixedly connected to the top of the connecting frame, a mounting plate fixedly connected to the top of the mounting plate, a three-dimensional road condition detection device and a road marking detection device fixedly connected to the top of each.

[0020] As a preferred solution of the present invention, the three-dimensional road condition detection device includes a three-dimensional structured light scanner, and the three-dimensional structured light scanner is also connected to an IMU inertial navigation unit and a GNSS positioning module respectively.

[0021] As a preferred solution of the present invention, the output end of the three-dimensional road condition detection device is also electrically connected to a data processing module.

[0022] As a preferred solution of the present invention, the marking detection device includes a high-definition camera, the top of the high-definition camera is fixedly connected to a camera mounting bracket, the side of the camera mounting bracket away from the high-definition camera is fixedly connected to a mounting block, and the high-definition camera is fixedly installed using the mounting block by bolts.

[0023] As a preferred solution of the present invention, the high-definition camera is also electrically connected to an image processing module, and a fill light is also provided on one side of the high-definition camera.

[0024] As a preferred solution of the present invention, the adjustment structure includes a protective cover fixedly mounted on one side of the square rod, a rotating gear is provided inside the protective cover, one side of the rotating gear is meshedly connected with a driving rack, and the driving rack is fixedly mounted on one side of the moving rod, and the interior of the rotating gear is also fixedly connected to a rotating handwheel through an axis.

[0025] As a preferred solution of the present invention, the movable rod and the square rod are locked and fixed with locking bolts.

[0026] Beneficial effect: In view of the problem that the existing technology for detecting three-dimensional road conditions and road markings in road surfaces in cold and high-altitude areas is relatively single and cannot achieve the purpose of joint detection, and usually requires multiple devices to perform multiple detections, which is inefficient, the present invention combines a three-dimensional road condition detection device and a road marking detection device together, and respectively utilizes the three-dimensional structured light scanner in the three-dimensional road condition detection device to adopt three-dimensional structured light scanning technology, binocular vision stereo imaging technology or three-dimensional laser scanning technology to perform high-precision scanning of road surfaces in cold and high-altitude areas, and can obtain three-dimensional point cloud data of the road surface and truly restore the three-dimensional scene of the road surface; at the same time, the high-definition camera in the road marking detection device is used to shoot the road markings and obtain image information of the markings, thereby achieving joint detection of three-dimensional road conditions and road markings in cold and high-altitude areas, improving efficiency and being very practical.
