Description

Technical Field

[0001] The present invention relates to the technical field of blasting construction, and in particular to an intelligent blasting auxiliary design system and method based on terrain simulation technology. Background Art

[0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in the air, water, soil and rock media or objects to achieve the desired purpose; when explosive bags or charges explode in soil and rock media or structures, the soil and rock media or structures will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork engineering, as well as the demolition of metal buildings and structures. Since blasting work is dangerous, it is often necessary to use some technology to assist in blasting operations to achieve safe, efficient and low-cost blasting goals. However, most of the current blasting auxiliary operations are to collect data on the scene during blasting and provide it to the blasters for reference. The blasters make the next blasting decision based on the current situation, which cannot provide a direct and effective reference plan for the blasters.

[0147] A parameter identification unit, configured to divide the blasting purpose into several execution items based on the distribution information of the blasting positions, draw a target contour corresponding to the blasting positions according to the execution items, determine a plurality of target parameters corresponding to each blasting position, and construct a plurality of parameter vectors corresponding to each blasting position according to the parameter differences between the target parameters corresponding to each blasting position and the corresponding contour parameters;

[0148] A parameter comparison unit, configured to establish a blasting execution queue according to the arrangement order of the execution items, determine the numerical correlation characteristics and dimension correlation characteristics between the corresponding blasting results and the blasting purpose according to the plurality of parameter vectors corresponding to each blasting position, and input the numerical correlation degree and the dimension correlation degree into the corresponding queue positions of the blasting execution queue to generate a blasting-related queue;

[0149] A deviation analysis unit is used to identify the result relevance between each blasting result and the blasting purpose in the blasting-related queue, and strengthen the corresponding numerical-related features and dimension-related features according to the result relevance to obtain the blasting result deviation features corresponding to each blasting position.

[0150] A suggestion generation unit is used to screen several target blasting positions whose blasting result deviation features do not meet the deviation error, and generate and display auxiliary blasting suggestions according to the corresponding target blasting result deviation features.

[0152] In this example, the blasting contour represents the contour presented at the blasting position after the blasting operation is completed.

[0153] In this example, the contour parameters represent the length, tortuosity, and contour range of the edge of the blasting contour.

For example: the blasting result is: blasting range [(1, 2, 3)-(5, 3, 4)], intensity 5.1, and the corresponding standard range in the blasting purpose is: [(2, 2, 3)-(2, 3, 5)], intensity 5.3, then the numerical-related feature is 0.96, and the dimension-related feature is: the coincidence degree between the blasting range and the standard range in three-dimensional space.

[0159] In this example, the deviation error represents the error allowed during the blasting operation, and this error is determined by the input of the blaster.

[0160] Working principle and beneficial effects of the above technical solution: To further improve the safety of blasting operations, a more refined auxiliary solution is designed. By using a visual data model to identify the contour parameters of the blasting profile at each blasting location, comparing them with the target parameters set for the blasting purpose, establishing corresponding parameter vectors, and then analyzing the correlation between the blasting results and the blasting purpose, the deviation characteristics of the blasting results at each blasting location are determined. Finally, auxiliary blasting suggestions are established for the blasting locations with excessive deviations, providing technical references for blasters to quickly eliminate the deviations and ensure the effectiveness of the blasting results.

[0179] The working principle and beneficial effects of the above technical solution: In order to better assist blasters in carrying out blasting work and improve the efficiency and quality of blasting work, before blasting, the terrain simulation technology is used to process the terrain data of the area to be blasted, generate a visual data model of the area to be blasted, and locate several blasting positions in the visual data model according to the blasting purpose, and then conduct blasting tests on them to preliminarily analyze the hardness of each blasting position, so as to match it with the appropriate required blasting force to generate a blasting operation plan. Then, when entering the blasting stage, collect the real-time blasting information of each blasting position and use the visual data model to simulate the blasting result of each blasting position, and analyze the blasting result deviation feature corresponding to each blasting position by analyzing the result correlation between the blasting result and the blasting purpose. In order to achieve the purpose of blasting assistance, when the blasting result deviation feature is too high, generate an auxiliary blasting suggestion. In this way, not only can a blasting operation plan be established before blasting to provide pre-guidance and reference for this blasting operation, but also during the actual blasting process, an auxiliary blasting suggestion can be constructed according to the real-time blasting situation. In this way, the blasting position can be determined most reasonably and precisely, and reasonable blasting assistance can be carried out to improve the work efficiency and work quality of blasters.
