[0030] The embodiments of the present invention achieve the following beneficial effects: The embodiment of the present invention automatically generates multiple applicable evaluation conditions and their weights by analyzing the second simulation content of the numerical simulation of jointed rock cutting carried out by the user in the second time period, and then evaluates the applicability of each auxiliary content to be selected; by calculating the applicability score of each auxiliary content to be selected, the auxiliary content that best suits the current situation can be accurately screened out, thereby providing the user with the most targeted and effective cutting simulation optimization assistance.

[0031] In one embodiment, the step S34, generating an interaction plan timeline of optimal auxiliary content, includes: S341, dividing the optimal auxiliary content into auxiliary levels to obtain hierarchical auxiliary content of multiple auxiliary levels; In S341, the optimal auxiliary content is hierarchically divided. The division may be performed according to the importance of the hierarchical auxiliary content or the priority of the user's needs. The larger the level, the higher the importance or the priority of the user's needs. For example, if the optimal auxiliary content includes basic data, model parameters, simulation graphics, etc., the basic data is divided into the first level, the model parameters are divided into the second level, and the simulation graphics are divided into the third level. S342, traverse each auxiliary level in order from small to large; S343, each time during traversal, based on the hierarchical auxiliary content of the traversed auxiliary level, planning the sight trigger area, the window display content and the content window area in the visual simulation space of the user relaying the numerical simulation of jointed rock mass cutting; In S343, the visualization simulation space is a space for performing numerical simulation of jointed rock cutting in the visualization display simulation process; the sight triggering area is an area to be triggered by the sight point when the user views the visualization simulation space; the window display content is the content that needs to be displayed to the user to assist the user after the sight point triggers the sight triggering area; and the content window area is a display area for the window display content; S344, generating an interaction plan, including: when the sight point of the user viewing the visual simulation space completely passes through the sight triggering area, setting a content window that displays the content of the window in the content window area; In S344, when the sight point of the user viewing the visual simulation space completely passes through the sight triggering area, the sight triggering area is triggered, and the content window displaying the content of the window is set in the content window area; complete triggering means that the sight point enters the sight triggering area and then exits the sight triggering area; S345, determining a target time period from the timeline; wherein the order of the target time period on the timeline is the same as the auxiliary level traversed, and there is a positive correlation between the length of the target time period and the auxiliary level traversed; In S345, the order of the target time period on the timeline is the same as the traversed auxiliary level, which means, for example, that if the traversed auxiliary level is 1, the order of the target time period on the timeline is also 1; the larger the traversed auxiliary level, the higher the importance of assisting the user, the more time is needed to assist the user, and the longer the length of the target time period; specifically, the positive relationship between the length of the target time period and the traversed auxiliary level can be set by the technician according to actual needs; S346, associating the interaction plan with the target time period; S347.

[0033] The embodiments of the present invention achieve the following beneficial effects: The embodiment of the present invention divides the optimal auxiliary content into auxiliary levels, and the importance of the content, the priority of user needs and other factors are considered during the division, so that when the user views the visual simulation space, the user can obtain customized and progressive support according to the auxiliary information of different levels, thereby effectively improving the user's work efficiency; secondly, each auxiliary level sets a different target time period, and sets the time length of the target time period according to its importance and the priority of user needs, so as to ensure that the user can obtain sufficient assistance at different stages, thereby improving the effectiveness of interaction; at the same time, the sight trigger area, the window display content and the content window area are introduced, and when the user's sight point completely passes through the sight trigger area, the window display content can be instantly presented through the content window area, thereby improving the timeliness and timeliness of the assistance; finally, by combining the dynamic interaction between the visual simulation space and the user's sight, according to different user needs and sight changes, the appropriate auxiliary content is flexibly displayed, the excessive display of information is avoided, and the auxiliary resources of the system are reduced, especially in the complex auxiliary application scenario of numerical simulation of jointed rock cutting, which can also support user operations more efficiently and accurately, thereby improving the simulation efficiency of numerical simulation of jointed rock cutting.

[0034] In one embodiment, the S343, based on the hierarchical auxiliary content of the traversed auxiliary level, planning the sight trigger area, the window display content and the content window area in the visual simulation space of the user relaying the numerical simulation of jointed rock cutting, includes: S3431, parsing the simulation sub-objects, simulation types and simulation parameters of the hierarchical auxiliary contents of the traversed auxiliary hierarchy; In S3431, hierarchical auxiliary content can help users to perform optimization simulation. The simulation sub-object is the object of optimization simulation, such as a jointed rock mass or a cutting surface. The simulation type is the type of optimization simulation, such as cutting parameter optimization. The simulation parameters are the setting parameters of the optimization simulation, such as cutting parameters. S3432, determining a simulation area of ​​a simulation sub-object from the visual simulation space; In S3432, the simulation area is a spatial area in the visual simulation space where the simulation sub-object is simulated; S3433, based on the associated area search rule of the simulation type, searching for at least one associated area within a preset area around the simulation area in the visual simulation space; In S3433, the simulation type corresponds to an associated area search rule, which is a rule indicating an associated area associated with the user's search location and the simulation area. For example, if the simulation area is a cutting area of ​​a jointed rock mass, the associated area search rule is to search for an area reflecting the stress state of the rock mass near the cutting area as an associated area; the preset area range may be within a sphere with a radius of 10 meters around the simulation area; S3434, creating a target viewing perspective for the simulation area and the associated area; wherein, in the visual simulation space, only the entire simulation area and the associated area are completely visible under the target viewing perspective; In S3434, when viewing the visual simulation space, it is viewed through the viewing perspective, and the field of view size parameters of the viewing perspective are fixed; create a target viewing perspective for the simulation area and the associated area. In the visual simulation space, only the entire simulation area and the associated area are completely visible under the target viewing perspective, and the simulation area and the associated area are irregular areas and will not be closely spliced, which makes the projection area of ​​the created target perspective in the visual simulation space have blank areas; S3435, determining a projection area of ​​the target viewing angle in the visualization simulation space; In S3435, the projection area of ​​the target perspective in the visualization simulation space refers to a spatial area in the visualization simulation space that falls within the visible range of the target perspective; S3436, using the blank area in the projection area as a sightline triggering area; In S3436, the blank area refers to the blank part of the viewing angle that is not occupied by the simulation area or the associated area. During the user's autonomous simulation, the user will continue to view the simulation area and the associated area to observe the simulation process. When the user is ready to make a decision, he will not view other unrelated simulation areas, but will not continue to view the simulation area and the associated area. His sight will pass through the blank area. Therefore, the blank area is used as a sight triggering area. For example, suppose that the user is carefully viewing the cutting area of ​​a rock mass and is also paying attention to the stress distribution (associated area) around the cutting area. In this process, the user's sight may shift from the simulation area (cutting surface) to the associated area (stress distribution map) around it. When the user is ready to make a decision (for example, whether to change the cutting method, whether to adjust the simulation parameters, etc.), he usually no longer needs to continue to look at the simulation area or the associated area, but will slightly deviate and view some blank areas. At this time, the blank area becomes the natural landing area of ​​the sight. When the system detects that the user's sight has focused on the blank area, it triggers the display of the relevant window content. S3437, generating window display content, including: simulation parameters and simulation results of simulation sub-objects after simulation according to the simulation parameter configuration; In S3437, the window display content includes simulation parameters and simulation results of simulation sub-objects after simulation by simulation parameter configuration. The simulation sub-objects are configured with simulation parameters, and they are automatically simulated to generate simulation results. The simulation parameters and simulation results are used as window display content to assist users, so that users can compare and analyze simulation results. When it is determined that the simulation results are better, the simulation parameters are adopted. S3438. Determine a content window area; wherein the content window area meets the display size requirement of the window display content, and the content window area is connected to the simulation area through the sight trigger area.

[0035] In S3438, the window display content has display size requirements, and it is necessary to ensure that the window display content is displayed clearly; it is also necessary to ensure that the content window area is connected to the simulation area through the line of sight trigger area, so that the content window area is not only adjacent to the natural landing area of ​​the user's line of sight, but also close to the simulation area, so that the user can directly feel that he or she is receiving targeted assistance visually.

[0036] The embodiments of the present invention achieve the following beneficial effects: The embodiment of the present invention accurately plans the sight trigger area and window content, optimizes the user's interactive experience during the numerical simulation of relay jointed rock cutting; parses the simulation sub-objects, simulation types and simulation parameters of the hierarchical auxiliary content of the traversed auxiliary levels, searches for the associated area based on the associated area search rule of the simulation type, reasonably creates the target viewing perspective based on the simulation area and the associated area, and determines the sight trigger area in its projection area. When the user thinks and makes decisions during the simulation viewing process so that the sight point naturally and completely passes through the sight trigger area, the system will trigger the window display content for output, ensuring that the user can obtain timely and accurate feedback, improving the simulation efficiency, and improving the user's decision-making efficiency and user experience; the determined content window area is close to the sight trigger area and the simulation area, providing users with a seamless interactive experience, helping them to quickly obtain optimization suggestions in the simulation operation, and facilitating the user to directly feel that they are receiving targeted assistance visually, further improving the user experience.
