[0042] The following embodiments refer to Figures 1 to 5 .

[0043] The embodiment of the present application provides a road marking machine system with a marking digitization function, including:

[0044] A road marking digitization unit, configured to determine the basic information of the target road marking, issue a key point collection instruction for the target road marking according to the basic information of the target road marking, and store the basic information of the target road marking and the key point collection instruction information at the same time;

[0045] A road marking positioning unit, configured to receive the key point collection instruction of the target road marking, collect the key point information in the construction spraying of the target road marking according to the key point collection instruction, and upload the collected key point information to the road marking digitization unit;

[0046] The road marking spraying unit is used to construct and spray the target road markings according to the preset road marking drawing.

[0047] Compared with the method of specifically collecting road information, a road marking machine system with marking digitization function in this application can collect the position of road markings during the spraying and marking process, realize the digitization of road markings during the spraying and marking process, provide digital road marking information for assisted driving and autonomous driving, and the information is accurate and reliable. The basic information of the target road markings and the key point collection instruction information stored in the road marking digitization unit, together with the key point information uploaded by the road marking positioning unit, constitute a complete road marking data system. At the same time, these data can be stored and accumulated for a long time, providing rich materials for subsequent road management and optimization. By analyzing these data, the usage situation, wear rules of road markings and traffic demand changes in different sections can be understood, so as to maintain, update and optimize the design of road markings in a targeted manner, and improve the utilization efficiency of road resources.

[0048] In addition, a road marking machine system with marking digitization function in this application, compared with the method of specifically collecting road information, can collect the position of road markings during the spraying and marking process, and its working method is more efficient and low-cost. At the same time, the road marking machine system of the present invention can be installed and modified on the existing road marking machine equipment. Only by updating and upgrading the existing marking machine can the digitization of road markings be realized during the spraying and marking process, with high cost performance and full utilization of existing resources.

[0049] Specifically, the road marking digitization unit includes:

[0050] The human-computer interaction module is used to identify the target operation of the construction personnel and determine the basic information of the target road markings according to the target operation of the construction personnel;

[0051] The basic information of the target road markings includes road name, construction method, marking material, marking type, marking color and marking size specification;

[0052] The marking types include lane dividing lines, stop lines and crosswalk lines; the marking colors include white, yellow, blue and orange; the marking size specifications include line width, length and spacing.

[0053] The key point generation module is used to generate the key point collection instruction of the target road markings according to the basic information of the target road markings; and send the key point collection instruction to the road marking positioning unit;

[0054] An information storage module is used to store the basic information of the target road marking, key point acquisition instructions, and key point information, and synchronously upload the stored data information to the backend server.

[0055] The key point information of the target road marking includes the starting point three-dimensional coordinates, turning point three-dimensional coordinates, midpoint three-dimensional coordinates, and ending point three-dimensional coordinates.

[0056] In specific implementation, the human-computer interaction module can choose to perceive the operation behavior of construction workers through various interaction methods (such as touch operation, voice recognition, gesture recognition, etc.). Then, these operations are analyzed and understood using pattern recognition or voice recognition to identify the target operation of the construction workers. According to the identified target operation, the human-computer interaction module guides the construction workers to input or directly obtain the basic information of the target road marking related to this operation according to the preset rules and database. For example, if the construction worker selects to set a "lane dividing line", the system will display an information input box related to the lane dividing line and require the construction worker to fill in specific contents such as road name, construction method, marking material, marking color, line width, length, and spacing. The convenience and accuracy of information input are improved through the human-computer interaction module. Construction workers can quickly convey their intentions through familiar interaction methods, avoiding the inconvenience and errors caused by traditional manual input or complex operations. At the same time, according to different operation requirements, the required basic information can be obtained targeted, ensuring that subsequent construction operations are carried out based on accurate information, providing reliable starting data for the entire road marking construction process.

[0057] In specific implementation, after receiving the basic information of the target road marking from the human-computer interaction module, the key point generation module will analyze it according to the design specifications and construction standards of road markings. For different types of markings (such as lane dividers, stop lines, crosswalk lines), their key point positions and collection requirements are different under different road conditions. By using the built-in preset algorithm logic and combining information such as the marking type, size specifications, and road name in the basic information, the key point positions that need to be collected during the construction spraying process of the target road marking are determined, such as the starting point, turning point, midpoint, and end point. Then, the position information of these key points and the relevant collection requirements are converted into key point collection instructions and sent to the road marking positioning unit for accurate position collection work. For example, for a straight lane divider, according to its length and starting position and other basic information, the positions of key points such as the starting point, midpoint, and end point to be collected are determined according to certain interval rules, and this information is converted into an instruction format and sent to the road marking positioning unit to guide its key point collection work. The key point generation module provides clear work guidance for the road marking positioning unit, enabling the positioning unit to accurately collect key position information during construction. This helps to ensure the accuracy and standardization of road marking construction, ensure that the shape, position, etc. of the markings meet the design requirements, thereby improving the quality and safety of road markings and avoiding inaccurate target road markings.

[0058] In specific implementation, the information storage module is responsible for receiving and storing the basic information of the target road marking obtained by the human-computer interaction module, the key point collection instructions generated by the key point generation module, and the key point information uploaded by the road marking positioning unit, facilitating subsequent query and management. At the same time, through network communication technology, the data information stored locally is synchronously uploaded to the backend server to achieve remote backup and sharing of data. The information storage module realizes the effective management and long-term preservation of data, providing a solid data foundation for the quality traceability, later maintenance, and data analysis of road marking construction. Construction personnel, management personnel, and technical personnel can query and call these data at any time to understand the construction process and results. The data is synchronously uploaded to the backend server, promoting data sharing and collaboration, improving work efficiency, and in terms of data security, reducing the risk of data loss through remote backup.

[0059] Specifically, the road marking positioning unit includes:

[0060] A positioning module for determining the position coordinates of the road marking machine; the positioning module is provided with a Beidou positioning module or a GPS positioning module, and is configured with an electronic gyroscope.

[0061] An information interaction module, configured to receive a key point collection instruction for a target road marking, and combine the position coordinates of the positioning module and the key point collection instruction to collect the position of key points during the construction spraying of the target road marking by the road marking spraying unit, and upload the collected position of key points to the information storage module of the road marking digitization unit.

[0062] In specific implementation, the Beidou positioning module or the GPS positioning module calculates the position coordinates of the road marking machine on the earth by receiving signals from Beidou satellites or GPS satellites. These satellites continuously send signals to the ground, containing the position and time information of the satellites. After the positioning module on the road marking machine receives the signals of multiple satellites, it calculates its own position coordinates (longitude, latitude, and altitude) according to the signal propagation time and the satellite position information by using the triangulation principle. Its positioning accuracy can reach the centimeter level, which can meet the position accuracy requirements of general road marking construction.

[0063] In addition, when the marking machine cannot receive satellite signals, it switches to an electronic gyroscope to determine the position information. The electronic gyroscope is mainly used to measure the angular velocity and angular displacement of the road marking machine and assist in positioning. When the road marking machine moves or changes direction, the electronic gyroscope can sense these changes and convert them into angle information. For example, when the road marking machine turns, the electronic gyroscope can accurately measure the turning angle, providing auxiliary information for accurately determining the attitude and motion trajectory of the road marking machine. In areas with poor satellite signals (such as tunnels, urban areas with high-rise buildings, etc.), the electronic gyroscope can, through the inertial navigation principle, calculate the position and attitude of the road marking machine within a short time based on the known initial position and the angular velocity and angular displacement information measured by itself, ensuring the continuity of the position information within a certain period of time.

[0064] Through the positioning module, the position coordinates of the road marking machine in different construction environments can be accurately determined, providing accurate position information for construction, ensuring the position accuracy of road markings, and avoiding marking deviations caused by position errors.

[0065] The use of the electronic gyroscope ensures that the continuity of the position information can still be maintained when the satellite signals are temporarily interrupted or unstable, avoiding chaos and delays caused by the loss of positioning information during the construction process, and improving the efficiency and reliability of the construction.

[0066] The information interaction module receives the key point collection instruction from the road marking digitization unit, and this instruction contains the collection requirements for the positions of the key points required in the construction spraying of the target road marking. At the same time, the information interaction module maintains real-time communication with the positioning module to obtain the current position coordinates of the road marking machine. When the road marking machine starts construction according to the construction plan, the information interaction module collects the required key point positions according to the key point collection instruction and the current position coordinate information. For example, when receiving the instruction to collect the starting point of the lane dividing line, the information interaction module continuously monitors the position information of the positioning module. Once it detects that the position coordinates are close to the expected starting point three-dimensional coordinates, it will record this position as the starting point three-dimensional coordinates.

[0067] The information interaction module can realize information interaction with the road marking digitization system, and upload the collected key point position information to the information storage module of the road marking digitization unit through a network communication protocol (such as the TCP / IP protocol). Before construction, it receives the key point collection instruction for the road marking collected by the road marking digitization system, collects the key point information of the road marking during construction, and uploads the key point information to the road marking digitization system.

[0068] Specifically, the road marking spraying unit includes:

[0069] The paint storage module is used to store paint;

[0070] The spraying module is used to spray road markings;

[0071] The control module is used to control the start, end and duration of road marking spraying, and transmit the construction data during the construction process to the road marking digitization unit.

[0072] Among them, during the process of controlling the construction, the control module can simultaneously complete the functions of collecting and recording data such as paint flow rate and spraying thickness during the construction process and transmitting them to the digitization unit.

[0073] In specific implementation, the paint storage module includes one or more specially designed storage containers, the size and shape of which are determined according to the design specifications of the road marking machine and the expected construction scope. The paint storage module cooperates with the control module for flow control and is configured with a monitoring system, which can accurately control the speed and flow rate of the paint flowing out of the storage container. These devices can transport the paint to the spraying module at a stable flow rate according to the specific requirements of the construction, ensuring the uniformity and thickness consistency of the marking spraying. For example, when receiving a construction signal, the control module will open the valve according to the set flow parameters and monitor the paint flow rate in real time through a flow sensor. If there is a deviation, it will promptly adjust the opening of the valve to ensure the stability of the flow rate. Through appropriate storage containers, different types of road marking paints can be stored and processed, improving the versatility and applicability of the road marking machine. At the same time, through the flow control and monitoring system, accurate control of the paint flow rate can be achieved, making the thickness of the sprayed marking uniform, avoiding uneven marking thickness caused by unstable paint flow rate, affecting the visual effect and service life of the marking, and also helping to control the paint usage and reduce the construction cost.

[0074] The spraying module usually consists of components such as nozzles, spray holes, and regulating valves. The shape and size of the nozzle determine the shape and scope of spraying. Different nozzles can produce markings of different widths. For example, narrow slit nozzles are used for narrow lane dividers, and wide-width nozzles are used for large-area crosswalks, etc. The size and distribution of the spray holes will affect the atomization degree of the paint and the spraying uniformity. By reasonably designing the spray holes, it can ensure that the paint is evenly sprayed on the road surface. The regulating valve can adjust the spraying pressure and angle of the paint to adapt to different construction requirements. For example, when spraying on different road surfaces (such as asphalt roads, cement roads) or different construction environments (such as flat sections, slope sections), the pressure and angle can be adjusted to ensure the adhesion effect and marking quality of the paint.

[0075] The spraying module is connected to the paint storage module and the control module. The control module issues corresponding signals, including controlling the start, end, and duration of spraying. For example, when the control module issues a spraying signal, the spraying module opens the valve, and the paint is sprayed onto the road surface through the spray holes under the action of pressure; when the signal ends, the nozzle closes. In addition, the spraying module can also achieve different spraying modes according to different marking types and construction requirements, such as continuous spraying (for straight markings) and intermittent spraying (for dotted markings).

[0076] The road marking spraying unit can accurately control the spraying range, shape, thickness, and mode according to different construction requirements, ensure that the shape and size of the road marking meet the design standards, improve the quality and aesthetics of the marking, and meet the construction requirements of different types and locations of road markings.

[0077] The embodiments of the present application further provide a working method for a road marking machine system with a marking digitization function, including:

[0078] Using the road marking digitization unit to determine the basic information of the target road marking, and issuing a key point collection instruction for the target road marking according to the basic information of the target road marking;

[0079] The road marking positioning unit receives the key point collection instruction of the target road marking, and collects the key point information during the construction spraying of the target road marking according to the key point collection instruction, and uploads the collected key point information to the road marking digitization unit;

[0080] The specific collection of the key point information during the construction spraying of the target road marking refers to collecting the key point information of the target road marking construction spraying by the road marking spraying unit according to the preset road marking drawing.

[0081] In this embodiment, after the paint is filled, start the road marking machine system that can realize marking digitization. The construction personnel select the road name, construction method, marking material, type, color, width, etc. of the road marking on the human-computer interaction module interface of the road marking digitization unit; after determining the basic information of the constructed road marking, on the one hand, these basic information will be stored in the road marking digitization unit as part of the digitized information of the constructed road marking, on the other hand, the road marking digitization unit determines which key points need to be collected for the constructed road marking according to the basic information, and sends the key point collection instruction to the road marking positioning unit; the road marking positioning unit receives the instruction, and the construction personnel start to spray the marking through the road marking spraying unit. During the spraying process, the road marking positioning unit collects the key point positions of the marking and transmits the position information to the road marking digitization unit in real time, becoming another part of the digitized information of the constructed road marking; after the spraying of this road marking is completed, the road marking digitization unit obtains the complete digitized information of the constructed road marking and packages this information separately. Then, carry out the spraying operation of the next road marking, repeat the above working process until the road markings in this section or this time period are completely constructed, and the road marking digitization unit uploads the information data to the backend system or downloads it manually to the flash device.
