Description

Technical Field

[0001] This utility model relates to the field of road marking technology, and in particular to a road pre-line marking device based on pile coordinates. Background Technology

[0002] In road construction, pile coordinates refer to the coordinates of a series of piles set up to accurately identify various locations in linear engineering projects (such as highways and railways). These piles typically have unique numbers, known as station numbers, used for quickly locating specific positions within the project. The calculation of pile coordinates involves various alignment types, including straight lines, circular curves, transition curves, compound curves, and hairpin curves, each with its own calculation method.

[0003] In road construction, determining the coordinates of road piles is crucial for construction, maintenance, and management. Calculating these coordinates allows for the precise location of various points along the road, ensuring construction accuracy and road smoothness. This is significant for improving road quality and lifespan. Pile coordinate calculations are typically based on known starting point coordinates, intersection angles, and starting edge azimuths. Using this information, the coordinates of all intersections along the entire route can be calculated, leading to the coordinates of each center pile. During the calculation process, different alignment and curve elements must be considered, such as the radius of circular curves and the length of transition curves.

[0004] Current methods for pre-marking highway lines require obtaining on-site parameters before marking the lines. This approach involves cumbersome preliminary work, a large workload, and significantly impacts the time required for pre-marking. Utility Model Content

[0005] To address the aforementioned problems, this invention utilizes pile coordinates as a benchmark for road location information, achieving precise recording of road coordinate positions. As a key control point in road construction, the accuracy and stability of pile coordinates are crucial for subsequent construction. This invention relates to a road pre-alignment device based on pile coordinates.

[0006] The technical solution adopted by this utility model is: a road pre-line marking device based on pile position coordinates, including pile position coordinates, a pre-line marking component, and a mobile trolley. The pile position coordinates are set on the road and used to record the road coordinate position. The pre-line marking component is used to make pre-line marks on the road. The mobile trolley travels on the road according to the position of the pile position coordinates. The pre-line marking component is set on the mobile trolley. The mobile trolley drives the pre-line marking component to travel on the road so as to make pre-line marks on the road during the travel.

[0007] A further improvement to the above scheme is that the pile position coordinates are composed of multiple main coordinates, which are continuously arranged along the length of the road, and multiple secondary coordinates are set between two adjacent main coordinates, with a distance 'a' between the multiple secondary coordinates.

[0008] A further improvement to the above scheme is that the mobile vehicle is equipped with a driving mechanism, a navigation mechanism, and a positioning mechanism. The positioning mechanism is used to locate the mechanism of the mobile vehicle, the navigation mechanism is used to navigate the mobile vehicle when it is driving, and the driving mechanism is used to drive the mobile vehicle to drive on the road.

[0009] A further improvement to the above scheme is that the driving mechanism includes a frame and a drive wheel set, the drive wheel set is mounted on the frame and is used to drive the frame to travel; the pre-line marking component includes a water tank, a water pump and a line-laying nozzle mounted on the frame, the water tank is connected to the line-laying nozzle through the water pump to pump the liquid in the water tank to the line-laying nozzle to spray and mark the line on the road surface.

[0010] A further improvement to the above scheme is that the mobile vehicle is equipped with a positioning acquisition module, which is used to acquire the coordinate point position of the pile position. The navigation mechanism provides the driving mechanism with the driving direction based on the position of the coordinate point, so as to mark the pre-line on the road.

[0011] The beneficial effects of this utility model are:

[0012] Compared to existing road pre-marking methods, this invention utilizes stake coordinates as a benchmark for road location information, achieving precise recording of road coordinate positions. Stake coordinates, as key control points in road construction, are crucial for subsequent construction due to their accuracy and stability. Stake coordinates obtained through high-precision measurement ensure that positional deviations during road construction are kept to a minimum, providing a reliable basis for road pre-marking. Secondly, the introduction of the pre-marking component makes marking pre-marks on the road simple and efficient. Pre-marking is a critical step before road marking, directly affecting the accuracy and aesthetics of road markings. Traditional pre-marking methods often require manual operation, which is not only time-consuming and labor-intensive but also difficult to guarantee accuracy and consistency. The pre-marking component, through mechanization and automation, can quickly and accurately mark pre-marks on the road, greatly improving construction efficiency and marking quality. Furthermore, the use of a mobile trolley further enhances the flexibility and adaptability of the device. The mobile trolley travels on the road based on the coordinates of the marker piles, automatically adjusting its route and speed to adapt to different road conditions and construction needs. Simultaneously, a pre-line marking component is mounted on the mobile trolley, which propels it along the road to mark the pre-line. This design not only simplifies the marking process and reduces labor costs but also improves the continuity and stability of the marking work.

[0013] This invention also boasts a high level of intelligence. By integrating an advanced navigation and control system, the mobile vehicle can perceive the road environment and vehicle status in real time, enabling precise path planning and obstacle avoidance. Simultaneously, the pre-marking components can be flexibly adjusted according to construction needs, such as changing the marking color, width, and shape, to meet the requirements of different road markings. By improving construction efficiency and marking quality, and reducing the waste of human and material resources, it provides a strong guarantee for the smooth completion of road construction projects. Furthermore, the device has high scalability and maintainability, allowing for functional expansion and performance optimization according to construction needs to adapt to future road construction trends.

[0014] The road pre-alignment method based on stake location coordinates uses stake location coordinates as a reference to accurately acquire stake location coordinate parameters. Stake location coordinates, as key parameters in road design, accurately reflect the geometric features and location information of the road. Accurate capture of stake location coordinates provides reliable data support for subsequent road pre-alignment. After acquiring the stake location coordinate parameters, this method converts them into driving navigation parameters to guide the mobile vehicle's navigation on the road. This conversion process fully considers the actual road conditions and the driving characteristics of the mobile vehicle, ensuring the accuracy and practicality of the navigation parameters. During operation, the mobile vehicle can travel along a predetermined road trajectory based on these navigation parameters, thereby achieving precise control of the road pre-alignment marking. A multi-line drawing strategy is adopted during the pre-alignment marking process. Each line drawing is based on the stake location coordinates, ensuring the accuracy and consistency of the marking. This multi-line drawing approach not only improves the clarity of the markings but also helps to promptly detect and correct potential errors, further improving the accuracy of road pre-alignment. It also demonstrates a high degree of automation and intelligence. By integrating advanced navigation systems and automated control technologies, the mobile vehicle can autonomously complete the entire process of road pre-alignment without human intervention or assistance. This not only reduces labor costs but also improves work efficiency, making road pre-alignment more convenient and efficient.

[0015] In the road pre-line marking method based on pile location coordinates, in step S3, the mobile trolley marks pre-lines on the road according to the converted driving navigation parameters. During this process, the trolley not only travels along the predetermined route but also adjusts its trajectory in real time based on the navigation parameters, ensuring that the drawing of pre-line a meets both design requirements and closely reflects the actual road conditions. The accurate drawing of pre-line a provides a reliable benchmark for the drawing of multiple subsequent pre-lines, making the entire road pre-line marking process more systematic and standardized. Furthermore, this method possesses excellent scalability and flexibility. Based on pre-line a, multiple pre-lines can be drawn to meet the road marking requirements under different road widths and traffic demands. This pre-line marking method based on a unified benchmark not only improves the accuracy of road markings but also significantly shortens the construction cycle and reduces manpower and material costs.

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-5As shown, in one embodiment of this utility model, a road pre-line marking device based on pile position coordinates is involved, including pile position coordinates 10, pre-line marking component 20, and a moving trolley 30. The pile position coordinates 10 are set on the road and used to record the road coordinate position; the pre-line marking component 20 is used to make pre-line marks on the road; the moving trolley 30 travels on the road according to the position of the pile position coordinates 10, and the pre-line marking component 20 is set on the moving trolley 30. The moving trolley 30 drives the pre-line marking component 20 to travel on the road, so as to make pre-line marks on the road during the travel. This utility model uses the pile position coordinates 10 as a reference for road position information, realizing the accurate recording of road coordinate position. As a key control point in road construction, the accuracy and stability of the pile position coordinates 10 are crucial for subsequent construction. The pile position coordinates 10 obtained by high-precision measurement means can ensure that the position deviation during road construction is controlled within a minimum range, providing a reliable basis for road pre-line marking. Secondly, the introduction of the pre-line marking component 20 makes making pre-line marks on the road simple and efficient. Pre-marking is a crucial step before road marking, directly impacting the accuracy and aesthetics of road markings. Traditional pre-marking methods often require manual operation, which is not only time-consuming and labor-intensive but also struggles to guarantee accuracy and consistency. The pre-marking component 20, through mechanization and automation, can quickly and accurately create pre-marking lines on the road, significantly improving construction efficiency and marking quality. Furthermore, the use of the mobile trolley 30 further enhances the flexibility and adaptability of the device. The mobile trolley 30 travels on the road based on the position of the stake coordinates 10, automatically adjusting its route and speed to adapt to different road conditions and construction needs. Simultaneously, the pre-marking component 20 is mounted on the mobile trolley 30, which propels it along the road, thus marking lines during travel. This design not only simplifies the marking process and reduces labor costs but also improves the continuity and stability of the marking work. In this embodiment, the pile position coordinate 10 is the center pile coordinate or the side pile coordinate of the road. The purpose is to identify the location of the road so that the moving trolley 30 can be positioned according to the coordinate position and the roadside.

[0025] This invention also boasts a high level of intelligence. By integrating an advanced navigation and control system, the mobile vehicle 30 can perceive the road environment and vehicle status in real time, enabling precise path planning and obstacle avoidance. Simultaneously, the pre-marking component 20 can be flexibly adjusted according to construction needs, such as changing the marking color, width, and shape, to meet the requirements of different road markings. By improving construction efficiency and marking quality, and reducing the waste of human and material resources, it provides a strong guarantee for the smooth completion of road construction projects. Furthermore, the device has high scalability and maintainability, allowing for functional expansion and performance optimization according to construction needs to adapt to future road construction trends.

[0026] The pile coordinate 10 is set at the center of the road. A first-direction road 11 and a second-direction road 12 are respectively set on both sides of the pile coordinate 10. The mobile trolley 30 is used to travel on the first-direction road 11 and the second-direction road 12 to perform pre-line marking. In this embodiment, once the pile coordinate 10 is established, the road is planned to both sides of the first-direction road 11 and the second-direction road 12 based on this coordinate. Guided by the pile coordinate 10, these two roads achieve precise control of parameters such as width, slope, and curvature, thereby ensuring the overall design quality and driving safety of the road. The mobile trolley 30 is specifically designed to travel on the first-direction road 11 and the second-direction road 12, and is equipped with high-precision sensors and line-laying equipment. During travel, the mobile trolley 30 can read road information in real time and perform precise line-laying operations according to preset parameters. The specific process for setting out and marking lines includes: First, the mobile trolley 30 calculates the specific location for setting out lines based on the coordinates of the pile position 10 and the road design parameters; then, the trolley travels along the predetermined trajectory and leaves clear and accurate pre-line marks on the road surface. These marks provide clear guidance for subsequent construction work, ensuring the smooth progress of road construction. In this embodiment, the coordinates of the pile position 10 are set at the center of the road, corresponding to the center pile coordinates. The mobile trolley 30 is positioned and navigated based on the location of the center pile coordinates.

[0027] In another embodiment, the pile coordinates 10 are set on the side of the road, corresponding to the edge pile coordinates. Similarly, the trolley 30 can be used for positioning and navigation based on the position of the edge pile coordinates.

[0028] The pile position coordinates 10 consist of multiple principal coordinates 13, which are continuously arranged along the length of the road. Multiple secondary coordinates 14 are set between adjacent principal coordinates 13, with a distance 'a' separating each secondary coordinate 14. In this embodiment, the pile position coordinates 10 are decomposed into multiple key principal coordinate points 13. These principal coordinate points 13 are continuously arranged along the length of the road, forming the basic framework of the road. To ensure the continuity and accuracy of road construction, multiple secondary coordinate points 14 are further set between adjacent principal coordinate points 13. These secondary coordinate points 14 not only serve as auxiliary positioning points but also provide more detailed reference benchmarks for road construction through their fixed distance 'a'. During the layout and calibration process, the device utilizes advanced measurement technology and equipment to accurately measure and calibrate the pile position coordinates 10.

[0029] In the specific implementation of the above embodiments, the following formula shall be referred to:

[0030] Mileage = K (primary coordinate) + 1 (secondary coordinate) + 020 (secondary coordinate distance)

[0031] With each primary coordinate K representing a distance of 1 kilometer, and secondary coordinates ranging from 1 to n, and each secondary coordinate having a distance a of 20 meters, the mobile trolley 30 travels according to the position of each secondary coordinate. The primary coordinate system positions the control points for each coordinate.

[0032] The mobile trolley 30 is equipped with a driving mechanism 31, a navigation mechanism 32, and a positioning mechanism 33. The positioning mechanism 33 is used to locate the mechanism of the mobile trolley 30, the navigation mechanism 32 is used for navigation when the mobile trolley 30 is moving, and the driving mechanism 31 is used to drive the mobile trolley 30 on the road. In this embodiment, the driving mechanism 31, navigation mechanism 32, and positioning mechanism 33 of the trolley are used to ensure the accuracy and efficiency of road pre-line marking. First, the positioning mechanism 33 of the mobile trolley 30 plays a crucial role. It uses high-precision sensors and algorithms to determine the precise position of the trolley on the road in real time, providing reliable basic data for subsequent line marking. Through precise docking with the pile coordinate system 10, the positioning mechanism 33 can ensure that the trolley always stays on the predetermined path during the driving process. Second, the navigation mechanism 32 is responsible for guiding the trolley along the predetermined route. It generates the optimal driving path based on road design data and pile coordinate information 10, and adjusts the driving direction of the trolley through real-time feedback. The high precision and real-time performance of the navigation mechanism 32 ensure that the trolley can drive stably and accurately even in complex road environments. Finally, the driving mechanism 31, as the key component driving the trolley forward, adopts advanced drive technology and control system. It can flexibly adjust the trolley's speed and steering angle according to the instructions of the navigation mechanism 32, ensuring that the trolley maintains a smooth and continuous driving state during the line setting and calibration process.

[0033] The driving mechanism 31 includes a frame 311 and a drive wheel set 312. The drive wheel set 312 is mounted on the frame 311 and is used to drive the frame 311. The pre-line marking assembly 20 includes a water tank 21, a water pump 22, and a line-laying nozzle 23 mounted on the frame 311. The water tank 21 is connected to the line-laying nozzle 23 via the water pump 22 to pump liquid from the water tank 21 onto the line-laying nozzle 23 to mark the road surface. In this embodiment, the driving mechanism 31 serves as the basic mobile platform for the entire device, and its design integrates the precise fit between the frame 311 and the drive wheel set 312. The frame 311, as a supporting structure, not only bears the overall weight of the device but also provides a stable mounting position for the drive wheel set 312. The drive wheel set 312, through its efficient transmission mechanism, drives the frame 311 to travel smoothly along the predetermined route, ensuring the continuity and stability of the road pre-line marking operation. The pre-marking component 20 is the core part of road marking. It cleverly integrates the water tank 21, water pump 22, and line-marking nozzle 23 onto the frame 311, forming a compact and efficient liquid spraying system. The water tank 21 serves as a liquid storage unit, storing the specific liquid used for road marking. The water pump 22 acts as a power source, using its powerful suction capacity to continuously and stably deliver the liquid in the water tank 21 to the line-marking nozzle 23. The line-marking nozzle 23, as the final liquid spraying component, is designed with full consideration of the uniformity and accuracy of spraying, ensuring the formation of clear and continuous marking lines on the road surface. The mobile trolley 30 is equipped with a positioning acquisition module, which is used to acquire the coordinate point position of the stake coordinate 10. The navigation mechanism 32 provides the driving mechanism 31 with the driving direction based on the position of the coordinate point to perform pre-marking on the road.

[0034] like Figures 1-5As shown, a road pre-alignment method based on pile coordinates 10 includes the aforementioned road pre-alignment device based on pile coordinates 10. The method includes the following steps: Step S1, obtaining the pile coordinates 10 parameters of the road to be pre-aligned; Step S2, converting the pile coordinates 10 parameters into driving navigation parameters to guide the mobile vehicle 30 in navigation; Step S3, the mobile vehicle 30 drives on the road according to the driving navigation parameters. During the driving process, pre-alignment markings are made on the road according to the driving navigation parameters. The pre-alignment markings are drawn at least multiple times, and each marking is based on the pile coordinates 10. The pile coordinates 10 are used as a reference to accurately obtain the pile coordinates 10 parameters. As a key parameter in road design, the pile coordinates 10 can accurately reflect the geometric features and positional information of the road. Accurate capture of the pile coordinates 10 provides reliable data support for subsequent road pre-alignment. After obtaining the pile coordinates 10 parameters, this method converts them into driving navigation parameters to guide the mobile vehicle 30 in navigation on the road. This conversion process fully considers the actual road conditions and the driving characteristics of the mobile vehicle 30, ensuring the accuracy and practicality of the navigation parameters. During operation, the mobile vehicle 30 can travel along a predetermined road trajectory based on these navigation parameters, thereby achieving precise control over the road pre-marking. A multi-line drawing strategy is employed during the pre-marking process. Each line is drawn based on the coordinates of the stake position 10, ensuring the accuracy and consistency of the markings. This multi-line drawing approach not only improves the clarity of the markings but also helps to promptly detect and correct potential errors, further enhancing the accuracy of road pre-marking. It also demonstrates a high degree of automation and intelligence. By integrating advanced navigation systems and automated control technology, the mobile vehicle 30 can autonomously complete the entire road pre-marking process without human intervention or assistance. This not only reduces labor costs but also improves work efficiency, making road pre-marking work more convenient and efficient.

[0035] A road pre-line calibration method based on pile coordinates 10 includes the aforementioned road pre-line calibration device based on pile coordinates 10; Step S1: Obtain the pile coordinates 10 parameters of the road to be pre-lined; Step S2: Convert the pile coordinates 10 parameters into driving navigation parameters to guide the movement of a mobile vehicle 30; Step S3: The mobile vehicle 30 travels on the road according to the driving navigation parameters, and during the travel, marks pre-line on the road according to the driving navigation parameters to obtain pre-line a, and then continues to draw multiple pre-line based on pre-line a. In step S3, the mobile vehicle 30 marks pre-line on the road according to the converted driving navigation parameters. In this process, the vehicle not only travels according to the predetermined route, but also adjusts its trajectory in real time according to the navigation parameters to ensure that the drawing of pre-line a meets both design requirements and closely reflects the actual road conditions. The accurate drawing of pre-line a provides a reliable benchmark for the drawing of multiple subsequent pre-line, making the entire road pre-line calibration process more systematic and standardized. In addition, this method also has excellent scalability and flexibility. Based on pre-line 'a', multiple pre-lines can be drawn to meet the road marking requirements under different road widths and traffic demands. This pre-line marking method based on a unified benchmark not only improves the accuracy of road markings but also significantly shortens the construction period and reduces labor and material costs.

[0036] In step S3, upon obtaining the navigation parameters, error compensation is performed. The error compensation value is the deviation between the road edge and the pile coordinate 10. The pile coordinate 10 consists of multiple primary coordinates 13, which are continuously arranged along the length of the road. Multiple secondary coordinates 14 are set between adjacent primary coordinates 13, and the secondary coordinates 14 are spaced apart by a distance 'a'. During error compensation, the error is first measured. During the measurement process, the moving trolley 30 travels along the direction of the secondary coordinates 14 and the distance between the road edge and the secondary coordinates 14 is obtained at intervals. Compensation is performed based on the error between the distance and the original pile coordinate 10 and the road distance. In this embodiment, error compensation is a crucial step in the road pre-alignment method based on pile coordinate 10, as it directly affects the accuracy and reliability of the final road alignment. After successfully obtaining the navigation parameters, we immediately perform error compensation processing. The core of this compensation lies in adjusting the deviation between the road edge and the pile coordinate 10. The pile coordinate system (10) serves as the benchmark for road calibration, consisting of a series of carefully selected primary coordinates (13) arranged continuously and orderly along the length of the road. To ensure the precision and accuracy of the calibration, multiple secondary coordinates (14) are cleverly placed between adjacent primary coordinates (13). These secondary coordinates (14) not only serve as a transition and refinement of the calibration intervals but also facilitate subsequent error measurements. The spacing 'a' between the secondary coordinates (14) is scientifically calculated to ensure measurement accuracy and efficiency. In the specific implementation of error compensation, we first measure potential errors. This process relies on a moving trolley (30) that travels smoothly along the direction of the secondary coordinates (14), intermittently acquiring distance data between the road edge and the secondary coordinates (14). This data provides valuable error information, enabling necessary adjustments to the original pile coordinates (10) and road distances based on actual conditions. Based on the above measurement data, error compensation calculations are performed, and the pile coordinates (10) are fine-tuned accordingly. This process ensures the accuracy of road calibration, making the final calibration results more consistent with the actual situation. This method of setting out and marking lines not only improves the accuracy of road construction but also provides strong support for subsequent road maintenance and management.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
