Description of the Drawings

[0027] Figure 1 It is a flow chart of an intelligent drawing recognition and processing method for a full-automatic cutting machine provided by the present invention. Detailed Embodiments

[0028] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0029] As Figure 1 shown, an intelligent drawing recognition and processing method for a full-automatic cutting machine provided by the present invention includes the following steps: S1, converting the processing data of the building information model through BIM software to obtain the engineering processing data of the pipe section; S2, converting the engineering processing data of the pipe section and outputting it as a processing code data file recognizable by the cutting machine; S3, converting the processing code data file through the system into coordinate cutting data in the X, Y, A, and B axes of the cutting machine, and the cutting machine starts automatic cutting and blanking according to the coordinate cutting data. This solution adds a certain conversion logic based on the existing system compilation, enabling the cutting machine to recognize and cut drawings intelligently, reducing the operation difficulty, improving the cutting efficiency, and saving costs. It avoids the trouble of manually calculating and converting the processing drawing data into cutting data in the X, Y, A, and B axes and inputting it into the cutting machine system in the operating system, and improves the data accuracy.

[0030] Feasibility demonstration analysis and experimental verification of this solution:

[0031] (1) The process of establishing a BIM model is formed by the combination of pipes, connectors, elbows, tees, valve components, etc. That is, the software itself can identify relevant components. By adding relevant logical judgments, the entire model can be split.

[0032] (2) After splitting, the entire model forms several component groups. By adding auxiliary logic, top views, front views, left views, and three-dimensional views are formed in the exported 2D drawings, and the views are marked in sequence. Since the software itself can identify relevant components, only the marking logic needs to be set to achieve markings that meet the processing accuracy. Through the above analysis, this technology is feasible.

[0033] An optional solution is that S1 specifically includes: obtaining the processing data of the pipe section number, length, diameter, and thickness by converting the building information model through BIM software. The pipe section includes pipes, connectors, elbows, tees, and valve components. The model includes multiple pipe sections. The model is automatically split by BIM software to obtain multiple pipe sections, and at the same time, the model data of each pipe section is converted into engineering processing data, such as 2D engineering drawings.

[0034] An optional solution is that S1 specifically includes:

[0035] S11, identify the components of the building information model. Through preset logical judgment criteria, while identifying, split the building information model to obtain multiple components, disconnect at the split point and set breakpoints;

[0036] S12, number the components after splitting is completed, obtain the views of each component and mark them correspondingly, and finally generate the engineering processing data of the pipe section.

[0037] Specifically, the principle is as follows:

[0038] (1) The building information model, hereinafter referred to as the model, is formed by the combination of pipes, connectors, elbows, tees, valve components, etc. based on the model. The BIM software itself can identify the corresponding components. Therefore, logical judgments are added during the identification process for splitting. For example, select a certain section of pipe. The logical judgments are in turn whether it is a straight pipe section. If so, it is divided into sections of 8 meters, and a flange is added at the end to disconnect. If not, a secondary judgment is made to see if there is an elbow. If there is, it is disconnected 0.5 meters to the right of the elbow and a flange is added; when there is no elbow, a third judgment is made to see if there is a tee. If there is, it is disconnected 0.5 meters from the branch pipe of the tee and a flange is added; when there is no tee, a fourth judgment is made to see if there is a valve component. If there is, the boundary on one side of the flange of the valve is used as a section. And so on, the model is split.

[0039] For a further solution, when making a secondary determination of whether there is an elbow, if there is one and there is also a second elbow within 0.6 meters on both sides of this elbow, then disconnect at 0.5 meters outside the second elbow and add a flange. When there is no elbow, make a third determination of whether there is a tee. If there is one and there are also tees within 2 meters on both sides of this tee, then disconnect at 0.5 meters outside each of the two tees and add flanges. When there is no tee, make a fourth determination of whether there is a valve component. If there is one and there is also a second valve within 0.6 meters on both sides of this valve component, then use the second valve as the boundary, with the inner and outer sides being regarded as separate segments respectively.

[0040] (2) After the splitting is completed, identify the break points of the splitting, sequentially run the numbering program for the components at each break point to obtain multiple numbered components, and then perform program commands on the identified and numbered components to generate a top view, a front view, a left view, and a 3D view. Through the recognizability of the components, sequentially perform program commands on each view:

[0041] 1. Taking the starting end as the endpoint, sequentially identify, and make a mark each time a component is identified.

[0042] 2. Mark each identified component separately.

[0043] 3. For the elbow, use the center as the marking point, and for the valve component, use the two end flanges as the marking points.

[0044] 4. Use the family mark to mark the names and dimensions of each component, and finally run the export command to generate 2D processing drawings.

[0045] This solution only needs to develop a simple instruction logic program to perform repeated operations of intelligent splitting and drawing, reducing the design workload. It can effectively improve the efficiency of the design part during the prefabricated construction process, thereby improving the drawing ability of the design and reducing the design cost.
