Description

TECHNICAL FIELD

[0001] The present application relates to the field of building technology, and in particular to a method and device for determining the quantity of a BIM model and a storage medium. BACKGROUND

[0002] In the prior art, the quantity calculation method based on the BIM model generally adopts a relatively primitive method, that is, by switching the connection relationship between components in Revit, the coincidence between components in the model is realized, and thus the quantity calculation is realized. However, the current method requires the modeler to be familiar with the quantity calculation rules, and the adjustment workload is large, and the rules cannot be quickly and flexibly adjusted according to the actual needs of the project to recalculate the quantity, which is basically a semi-automatic quantity calculation. Alternatively, in another way, without adjusting the connection relationship between components, the deduction between components in the model is realized, and thus the automatic calculation of the quantity is realized. However, such a method cannot accurately handle complex or new model scenarios, multiple component continuous deduction, and mutual repeated deduction between components, thereby affecting the accurate calculation of the quantity.

[0043] In order to make the purpose, technical scheme and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0044] In the prior art, the BIM model-based engineering quantity calculation method generally adopts a relatively primitive method, that is, the connection relationship between the components is switched within Revit to realize that there is no overlap between the components in the model, thereby realizing the calculation of the engineering quantity. However, the current method requires the modeler to be familiar with the engineering quantity calculation rules, and the adjustment workload is large, and the rules cannot be quickly and flexibly adjusted according to the actual needs of the project to recalculate the engineering quantity, which basically belongs to semi-automatic engineering quantity calculation. Alternatively, in another way, without adjusting the connection relationship between the components, the deduction between the components in the model is realized, thereby realizing the automatic calculation of the engineering quantity. However, such a method cannot accurately handle complex or new model scenarios, multiple component continuous deduction, and repeated deduction between components, thereby affecting the accuracy of the engineering quantity calculation. As can be seen, the existing BIM model-based engineering quantity determination method is relatively complex and is based on the overall calculation method, which is difficult to ensure the accuracy of the engineering quantity calculation.

[0045] In order to solve the above technical problems, the present embodiment provides a BIM model engineering quantity determination method, which comprises: acquiring a current component, determining a collision component that exists collision with the current component, and obtaining a collision relationship between the current component and the collision component; determining the arrangement order of the collision component based on a preset deduction order; acquiring a deduction rule corresponding to the collision relationship, and based on the arrangement order and the deduction rule, using the collision component to perform collision deduction on the current component to obtain the engineering quantity of the BIM model, wherein the engineering quantity includes volume and area. The present application can sort the collision components that exist collision with the current component according to the rules, and then perform collision deduction on the current component one by one based on the collision components according to the arrangement order and the deduction rules, instead of using the overall calculation method, which greatly reduces the complexity of the scene during collision deduction, ensures the accuracy of the collision deduction, and finally ensures the accuracy of the engineering quantity calculation.

[0046] Exemplary method

[0047] The BIM model engineering quantity determination method of the present embodiment can be applied to a terminal device, which is a smart terminal product such as a mobile phone, a smart television, a computer, etc. Specifically, as shown inFigure 1 The method for determining the engineering quantity of the BIM model in the embodiment includes the following steps:

[0048] In step S100, a current component is acquired, a collision component in collision with the current component is determined, and a collision relationship between the current component and the collision component is obtained.

[0049] In the embodiment, when the terminal device performs engineering quantity calculation based on the BIM model, the terminal device first acquires a current component. Since the current component overlaps with other components in a BIM model, in order to accurately calculate the engineering quantity of each current component, the terminal device acquires all collision components in collision with the current component after acquiring the current component. The collision component is a component in collision with the current component. When the collision component is determined, the terminal device can also determine the collision relationship between the current component and each collision component.

[0050] In an implementation manner, when the collision component is determined in the embodiment, the following steps are included:

[0051] In step S101, the current component is acquired, and a component category of the current component is determined.

[0052] In step S102, a preset deduction rule is acquired according to the component category, and a collision component in collision with the current component is determined based on the deduction rule.

[0053] In implementation, when the collision component is determined in the embodiment, the deduction rule of the component is established according to various component categories in advance. The deduction rule can be used to determine which components are in collision with the current component when the engineering quantity of the current component is calculated, and the current component can be collided according to the deduction rule. Specifically, the engineering quantity in the embodiment includes volume, formwork area, projection area, and wall area. In summary, the calculated engineering quantity includes two categories, volume and area. Therefore, the deduction rule includes volume deduction rule and area deduction rule. For example, when the volume of the current component is calculated, whether the volume of the current component is deducted is determined according to the volume deduction rule after the current component collides with other components. Alternatively, when the area of the current component is calculated, whether the area of the current component is deducted is determined according to the area deduction rule after the current component collides with other components.

[0054] In an implementation manner, the embodiment pre-establishes deduction sequences of all components, and the deduction sequences are used to determine the order of deduction according to the deduction sequences when the quantities of the current component are calculated after the current component collides with other components. The embodiment opens the BIM model by using Revit, and when the current component is obtained from the BIM model, the embodiment first determines the component category to which the current component belongs. Since each component category has a corresponding deduction rule, the embodiment obtains the preset deduction rule according to the component category, and then determines the collision components that collide with the current component based on the deduction rule. In the embodiment, the collision components are the components that overlap with the current component. After the collision components are determined, the embodiment can further determine the collision relationship between each collision component and the current component. The collision relationship can be overlapping or non-overlapping.

[0055] In step S200, the arrangement order of the collision components is determined based on the preset deduction sequence.

[0056] In the embodiment, after the collision components are determined, the embodiment sorts the collision components based on the preset deduction sequence to obtain the arrangement order of the collision components. Specifically, since the deduction sequence corresponds to the collision components, and each collision component corresponds to a component category, the embodiment can sort the collision components based on the deduction sequence to obtain the arrangement order of the collision components. The arrangement order refers to the order of using the collision components to deduct the current component.

[0057] In step S300, the deduction rule corresponding to the collision relationship is obtained, and the current component is deducted by the collision components one by one based on the arrangement order and the deduction rule, to obtain the quantities of the BIM model. The quantities include volume and area.

[0058] In the embodiment, the engineering quantity includes volume and area, so when the engineering quantity of the current component is deducted by collision, the volume deduction rule or the area deduction rule is used respectively. Specifically, when the engineering quantity is volume, it means that the volume of the current component needs to be calculated, and the collision relationship between the current component and the collision component is obtained. If the collision relationship is coincidence, the coincidence body between the collision component and the current component is determined; then the original volume of the current component is deducted by collision based on the volume of the coincidence body, that is, the original volume of the current component is reduced by the volume of the coincidence body to obtain the remaining volume, and the remaining volume is taken as the engineering quantity of the BIM model. If the collision relationship is non-coincidence, no volume deduction by collision is performed. In addition, after the volume deduction by collision of the current component by the collision component is completed, it is judged whether all the collision components have completed the volume deduction by collision of the current component; if the volume deduction by collision is not completed, the current component is subjected to volume deduction by collision using the collision component (i.e. the next collision component) which has not completed the volume deduction by collision, until all the collision components complete the volume deduction by collision.

[0059] When the engineering quantity is area, it means that the area of the current component needs to be calculated, and the collision relationship between the current component and the collision component is obtained. The collision relationship in the embodiment includes coincidence with contact (i.e. body coincidence but with surface contact), coincidence without contact (i.e. body coincidence but without surface contact), and only contact (i.e. no body coincidence but with surface contact). If the collision relationship is coincidence with contact, the coincidence body between the collision component and the current component is determined; based on the coincidence body, the first outer surface of the collision component and the current component which simultaneously exists in the coincidence body is determined, that is, the surface of the collision component which contacts the outer surface of the current component is determined, and the second outer surface of the current component which exists in the coincidence body is determined, that is, the surface of the current component inside the collision component (including the contact surface) is determined. Then, it is determined whether the deduction order of the current component is higher than that of the collision component; if the deduction order of the current component is higher than that of the collision component, the current component is preferentially deducted, and the first outer surface in the second outer surface is removed to perform area deduction by collision on the original area of the current component, that is, the original area of the current component is reduced by the area of the first outer surface to obtain the engineering quantity of the BIM model; if the deduction order of the current component is lower than that of the collision component, the original area of the current component is deducted by collision based on the second outer surface to obtain the engineering quantity of the BIM model.

[0060] If the collision relationship is coincident and non-contact, a coincident body between the collision component and the current component is determined. Based on the coincident body, a second outer surface of the coincident body existing on the outer surface of the current component is determined. At this time, the second outer surface only exists on the current component, and thus the current component is coincident and non-contact with the collision component. Then, based on the second outer surface, the original area of the current component is subjected to area collision deduction, that is, the original area of the current component is reduced by the area of the second outer surface to obtain the engineering quantity of the BIM model. If the collision relationship is contact, a contact surface between the collision component and the current component is determined. At this time, the current component is only in contact with the collision component. Based on the contact surface, the original area of the current component is subjected to area collision deduction, that is, the original area of the current component is reduced by the area of the contact surface to obtain the engineering quantity of the BIM model. Similarly, after the collision component completes the deduction of the current component, it is judged whether all the collision components have completed the area collision deduction of the current component. If the area collision deduction is not completed, the collision component (that is, the next collision component) which has not completed the area collision deduction is used to continue the area collision deduction of the current component until all the collision components complete the area collision deduction. After all the collision components complete the area collision deduction of the current component, the area of the current component after the deduction is the correct area of the current component, that is, the engineering quantity is obtained.

[0061] In summary, the embodiment obtains a current component, determines a collision component in collision with the current component, and obtains a collision relationship between the current component and the collision component. Based on a preset deduction order, the arrangement order of the collision components is determined. The deduction rule corresponding to the collision relationship is obtained, and based on the arrangement order and the deduction rule, the current component is subjected to collision deduction by using the collision components to obtain the engineering quantity of the BIM model, wherein the engineering quantity includes volume and area. The embodiment can sort the collision components in collision with the current component according to the rules, classify all the collision relationships, and the classified categories are simple and easy to understand. Then, the current component is subjected to collision deduction by the collision components one by one according to the arrangement order and the deduction rule, instead of using the overall calculation mode, which greatly reduces the scene complexity during collision deduction, ensures the accuracy of collision deduction, and finally ensures the accuracy of engineering quantity calculation.
