Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the embodiments of this application and are not intended to limit the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application all comply with relevant laws and regulations. In the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solution of this application, and do not imply that the applicant has already used or necessarily used such solutions.

[0020] In one embodiment, such as Figure 1 , Figure 2 As shown, this application provides a method for generating equipment drawings based on key points of components, including: S102, Obtain drawing generation request; the drawing generation request carries equipment operating parameters.

[0021] The drawing generation request is a user instruction returned from the front end, mainly carrying the user's identity information and equipment operating parameters, used to define the equipment drawings the user wants to generate. Equipment operating parameters are a set of variables used to determine the equipment's configuration. These may include equipment type, equipment model, boom assembly type, main boom length, vehicle counterweight, turntable configuration, additional configurations, and slewing angle, etc. Taking cranes as an example, equipment types may include crawler cranes, all-terrain cranes, truck cranes, etc., and boom assembly types may include main boom, fixed jib, tower jib, flying boom, etc.

[0022] S104. Query the pre-built operating condition database according to the equipment operating condition parameters to obtain vector diagrams of multiple corresponding equipment appearance components; the operating condition database stores at least the vector diagrams of all equipment appearance components required for each operating condition of the equipment, as well as the mapping relationship between equipment operating condition parameters and equipment appearance components.

[0023] The operating condition database is a pre-built structured database that stores vector graphics and CAD drawings of all equipment exterior components required for various operating conditions, as well as the mapping relationship between equipment operating condition parameters and equipment exterior components. The vector graphics of the equipment exterior components are vector graphics files used for front-end display and splicing; they can be SVG images, AI images (Adobe Illustrator), etc., and contain key points defined through pre-coding, which exist in the form of attributes. The CAD drawings of the equipment exterior components are source files used for high-precision output and key point pre-coding. They can be opened and modified using professional software such as AutoCAD, DraftSight, and FreeCAD, and can include DWG format, DXF format, SLDDRW, etc.

[0024] S106. Based on the preset topology connection rules and the initial attitude parameters in the equipment operating parameters, all vector graphics are spliced ​​at the key points of the equipment's exterior components, and the splicing result is displayed on the front-end page.

[0025] Among them, topology connection rules refer to the logical rules defining how components are connected. It explicitly specifies that a key point of component A is connected to a key point of component B. For example, the key point of the main arm on the host is defined as "mainboom_install_socket", and the key point at the bottom of the main arm that is installed on the host is named "mainboom_install_plug_loc". During splicing, the key point of the main arm is connected to the key point of the host.

[0026] Initial attitude parameters refer to the initial position state of movable parts of the device that are not fully extended or fully retracted.

[0027] Key points of equipment appearance components refer to geometric points that are predefined and coded on the component's CAD drawing. These points represent the locations where components are docked or connected. One specific implementation method is to convert the geometric figures representing these points in the corresponding dxf file of the CAD drawing into blocks with a naming convention, and to precisely set the base point of the block at the center of that point. Its name is the key point code.

[0028] The splicing result refers to the complete visual graphic of the device under a specific working condition rendered on the front-end page, which has dynamism and interactivity.

[0029] S108: Generate equipment drawings based on the splicing results displayed on the current page.

[0030] Equipment drawings are drawing documents used to guide production, construction, and scheme review. They are generated based on the associated data of the splicing results and include information such as dimension annotations, project name, drawing number, version, a list of major components in the drawing, and core parameters such as lifting capacity, working radius, and elevation angle under this working condition.

[0031] This method can quickly and automatically generate various equipment configuration diagrams by changing the operating parameters, without the need for manual redrawing. The spatial position is calculated from the coordinates in the diagram, avoiding errors caused by manual placement. It has flexibility and accuracy, and provides a data foundation for subsequent applications such as operating condition simulation, stress analysis, and hoisting scheme planning.

[0032] In one embodiment, the vector diagram of the device's exterior components includes at least the main arm and the main unit. The step of stitching all the vector diagrams at key points of the device's exterior components according to preset topology connection rules and initial attitude parameters in the device's operating parameters includes: determining the connection relationship between the main arm and the main unit in the vector diagram according to the topology connection rules; obtaining the key point coordinates of the main arm and the main unit; moving the spatial position of the main arm according to the connection relationship so that the key point coordinates of the main arm coincide with the corresponding key point coordinates of the main unit; and adjusting the amplitude of the main arm with the coincident key point as the center according to the initial attitude parameters.

[0033] Initial attitude parameters may include initial luffing parameters and initial hoisting parameters. Initial luffing parameters refer to the initial elevation angle of the boom. Initial hoisting parameters refer to the initial height of the hook, which determines the length of the wire rope that can be wound up or down, thus affecting the distance of the hook from the ground or from the boom tip.

[0034] In the front-end splicing process, the position and angle of each component's vector graphic in the image are calculated according to the topology connection rules and initial posture parameters. Then, they are aligned at key points to render the device graphic. Taking the vector splicing of the main arm and the host as an example, the two key points that the main arm and the host need to be connected are determined according to the topology connection rules. The position of the host is taken as the starting position. The absolute coordinates of the two key points on the canvas are made to coincide by translating the main arm. The main arm is rotated with the coincident key point as the center. The pseudocode for this section is described as follows: The bottom mounting point "mainboom_install_plug_loc" on the main boom coincides with the center of the main boom "mainboom_install_socket" on the host machine, and rotates 81.95° around this coincident center. This rotation angle can be calculated based on the right triangle established by the main boom length and minimum working radius; the bottom key point "mast_install_plug_loc" on the mast coincides with the center of the mast key point "mast_install_socket" on the host machine; the key point "mast_top_link_poin" on the host machine connecting to the top of the mast coincides with the line point "mast_top_link_point" at the top of the mast; the key point "mast_top_link_point" at the top of the mast coincides with the line point "mainboom_mast_link_point" at the top of the main boom; the key point "mainboom_sheave_wirerope_out" on the wire rope pulley at the top of the main boom coincides with the line point "main_hook_boom_link_point_loc" on the hook.

[0035] In one embodiment, the operating condition database also stores CAD drawings of all equipment exterior components required for each operating condition of the equipment; after the step of displaying the splicing result on the front-end page, the method further includes: receiving simulated attitude parameters, which include at least one of target amplitude parameters, target hoisting parameters, and target rotation parameters; and according to the simulated attitude parameters and topology connection rules, re-splitting all vector graphics at key points of their equipment exterior components to generate a new splicing result and displaying it on a new page on the front end.

[0036] The CAD drawings of equipment exterior components may include basic graphic elements such as straight lines, circles, arcs, and polylines that constitute the shape of the components, the precise dimensions of each component, and pre-coded key points. It should be noted that the file format of the CAD drawings can be switched according to the actual application scenario, and the pre-coded key points can be changed according to the equipment type.

[0037] Simulated attitude parameters refer to control commands input by the user to adjust a specific state of the simulated equipment. Target luffing parameters refer to the required range of motion of the boom and other equipment; target hoisting parameters refer to the lifting and lowering of the hoisting system; and target slewing parameters refer to the rotation range of the boom and other equipment relative to the chassis. In this embodiment, functions such as luffing adjustment, hoisting adjustment, and left / right slewing are provided to adjust the rotation angles of the equipment and boom so that the equipment drawings support various operating modes, such as... Figure 6 (a) Figure 6 As shown in (b), a front view is generated upon receiving the initial attitude parameters to most intuitively display the relationship between the boom's elevation angle, amplitude, and height. The boom can be adjusted according to functions such as luffing and winch adjustment. At the same time, a top view can be provided to display the boom's projection direction on the horizontal plane, slewing radius, etc.

[0038] In a specific embodiment, such as Figure 7 (a) Figure 7 As shown in (b), the display of the front view can be adjusted according to the target rotation parameters. For example, see... Figure 7 (a) is a front view of the equipment with the rotation angle at 0°. Figure 7 (b) is a front view of the equipment with a rotation angle of 90°. When the rotation angle in the target rotation parameter is between 315° and 44°, the chassis in the front view points to the right. The orientation of the chassis in the front view changes every 90° rotation. When the rotation angle is between 45° and 134°, the chassis points to the front; when the rotation angle is between 135° and 224°, the chassis points to the left; and when the rotation angle is between 225° and 314°, the chassis points to the rear. This is to facilitate the user's simulation of the equipment's motion control. It should be noted that the control functions can be added or reduced according to the drawings of each direction and the predefined topology connection rules stored in the working condition database. No limitation is made here.

[0039] In one embodiment, such as Figure 8 As shown, the steps for generating equipment drawings based on the splicing results displayed on the current page include: responding to the drawing export command, obtaining equipment operating parameters corresponding to the splicing results displayed on the current page; querying the operating database based on the equipment operating parameters to obtain CAD drawings of multiple corresponding equipment appearance components; and splicing all CAD drawings at key points of the equipment appearance components according to the topology connection rules and the final attitude parameters in the equipment operating parameters to generate equipment drawings.

[0040] After the front-end is adjusted, the user can export the equipment drawings. The back-end receives the crane operating parameters, working range, hoisting height and other equipment operating parameters from the front-end. Then, according to the unified topology connection rules, it assembles the CAD drawings of the required equipment appearance parts into a new crane posture drawing and transmits it to the user.

[0041] In one embodiment, such as Figure 3 As shown, the steps for generating key points of the equipment's exterior components include: obtaining CAD drawings of the equipment's exterior components; encoding the center of the mating circle in the CAD drawing as a key point and saving it as an encoding file.

[0042] During product development, a large number of component drawings will be generated. First, it is necessary to collect drawings of relevant equipment exterior components, which may include the main unit, main boom, auxiliary boom, mast, strut, gooseneck frame, hook, etc., and name each drawing according to the naming convention. For example, the main unit drawing of ZCC1500V-1 is named "ZCC1500V-1_carrier.dxf", the 19-meter main boom drawing in S condition is named "ZCC1500V-1_mainboom_S_19.0.dxf", the mast drawing is named "ZCC1500V-1_mast.dxf", the 80-ton main hook is named "ZCC1500V-1_mainhook_80.0.dxf", and so on.

[0043] According to the key point naming convention, key points in the CAD drawings of exterior components are encoded. One specific implementation method is to select the circle corresponding to the key points used for docking and connecting in the DXF file using AutoCAD's block definition function, define this circle as a block with a specified name, and assign the block's base point to the corresponding circle's center. This encoding process can be implemented using Python to achieve one-click batch encoding of key points in CAD drawings, or it can be implemented using other programming languages ​​such as C++, C#, and Java.

[0044] In one embodiment, such as Figure 4 As shown, the steps for generating a vector graphic of a device's exterior components include: obtaining an encoding file; parsing the graphic entities and coordinate data in the encoding file; mapping the graphic entities to corresponding vector elements in a blank vector graphic and drawing the image based on the coordinate data; encoding the key points in the graphic entities as semantic attributes and synchronizing them to the corresponding elements in the vector graphic to generate a vector graphic of the device's exterior components.

[0045] This process involves converting the encoded file into structured vector graphics while preserving the semantic encoding information of key points. The encoded file is traversed and each graphic entity within it is parsed, including entities such as lines, polylines, circles, and arcs. Data for each graphic entity is extracted and converted into uniform trajectory coordinates. One possible implementation is to create a blank SVG file, ensuring its internal coordinate system aligns with the world coordinate system of the DXF file by setting its attributes. The trajectory data of each graphic entity is then converted into corresponding vector elements, which can include lines, circles, polylines, etc. Graphic entities defined as blocks in the encoded file with names conforming to the encoding specifications are identified, and the key point encoding is synchronized as semantic attributes to the corresponding elements in the vector graphics. This encoding process can be implemented using Python, or other programming languages ​​such as C++, C#, and Java.

[0046] After the above method is completed, there is one set of data corresponding to two sets of drawings. The user's front end sees a crane drawing composed of vector drawings spliced ​​together and connected, while the exported equipment drawing is generated from the CAD drawing file of the appearance component. This ensures that the front end rendering and the back end generation are independent of each other, avoiding drawing conversion during the simulation and adjustment process.

[0047] In one embodiment, such as Figure 5 As shown, the steps for establishing the operating condition database include: determining the combination of equipment appearance components required for different operating conditions based on the equipment's operation manual, in order to establish a mapping relationship between equipment operating condition parameters and equipment appearance components; and storing the mapping relationship, coded files, and vector graphics together to construct the operating condition database.

[0048] The mapping relationship in the operating condition database defines the correspondence between equipment operating condition parameters and a list of vector graphics files and CAD drawing files of the specific components required for that operating condition. For example, querying the drawings of the main unit, main hook, and main booms of different lengths required for the ZCC1500V-1 S operating condition will return the drawing codes for the main unit, main hook, mast, strut, gooseneck, hook, strut, and various main booms. Based on this operating condition database, the corresponding drawings can be quickly located according to the request returned by the front end, improving database query efficiency. Simultaneously, drawings from various directions and components in product development can be integrated; only one set of CAD drawings for each orientation needs to be collected, converted, and uploaded to the server to allow users to select operating condition parameters for hoisting simulation.

[0049] In one embodiment, such as Figure 9 As shown, this application also provides a device 900 for generating equipment drawings based on key points of components. The device includes: The request acquisition module 901 is used to acquire drawing generation requests; the drawing generation requests carry equipment operating parameters.

[0051] The drawing display module 903 is used to stitch all vector graphics at key points of the equipment's exterior components according to preset topology connection rules and initial attitude parameters in the equipment's operating parameters, and display the stitching result on the front-end page.

[0052] The drawing generation module 904 generates equipment drawings based on the splicing results displayed on the current page.

[0053] In one embodiment, the vector diagram of the device's exterior components includes at least the main arm and the host; the drawing display module 903 is specifically used to determine the connection relationship between the main arm and the host in the vector diagram according to the topology connection rules; obtain the key point coordinates of the main arm and the host; move the spatial position of the main arm according to the connection relationship so that the key point coordinates of the main arm coincide with the corresponding key point coordinates of the host; and adjust the amplitude of the main arm with the coincident key point as the center according to the initial attitude parameters.
