If there are multiple BIM component models corresponding to the search key, the search unit may calculate the calling frequency of each BIM component model in the BIM component models corresponding to the search key according to a component calling frequency calculation formula. Wherein the component call frequency calculation formula is preset.
For example, the component calling frequency calculation formula is:
wherein, FkRepresents the calling frequency of the k-th-level BIM component model,

Specifically, the BIM component models may be classified according to their composition, such as equipment models, ironmaking equipment models, ore tank equipment models, mobile dump trucks, the higher the grade the more complex the BIM component models are. The calling frequency of the BIM component model at the lowest level is obtained according to the statistics of the actual calling frequency, and for the BIM component model not at the lowest level, the BIM component model at the lowest level can be obtained according to a formula

For example, all BIM component models are divided into four levels, the first level being the lowest level and the fourth level being the highest level. And the calling frequency of each BIM component model in the first-stage BIM component model is obtained according to the actual calling frequency statistics. The frequency of calling BIM component models of the second, third and fourth stages is according to the formula
And (6) calculating. Suppose that the second-level BIM component model A includes five first-level BIM component models A1、A2、A3、A4And A5Obtaining BIM component model A through statistics1The actual calling frequency of (A) is 5, the BIM component model A2The actual calling frequency of (A) is 10, the BIM component model A3OfThe inter-call frequency is 15, BIM component model A4The actual calling frequency of (A) is 0, and the BIM component model A5Has an actual calling frequency of 5, then the calling frequency F of the BIM component model A2＝α(5+10+15+0+5)/5＝5α。
For example, fig. 9 is a schematic diagram of a BIM component invocation interface provided in an embodiment of the present invention, and a certain component invocation module below an application layer is clicked at a client, so that the interface shown in fig. 9 is displayed. The user inputs part of the name of the component in the search bar as a search key, the search unit of the component calling module can receive the search key, then queries the component name included in the component information through the data layer, takes the BIM component model including the search key in the component name as the BIM component model corresponding to the search key, and assumes that five BIM component models are queried: BIM component model a, BIM component model b, BIM component model c, BIM component model d, and BIM component model e.
The retrieval unit acquires the calling frequency of the five BIM component models. If the BIM component model a, the BIM component model b, the BIM component model c and the BIM component model d are not the BIM component model of the lowest level, the BIM component model e is the BIM component model of the lowest level, the retrieval unit obtains the calling frequency of the BIM component model e according to the actual calling frequency of the BIM component model e, and the retrieval unit respectively calculates and obtains the calling frequency of the BIM component model a, the calling frequency of the BIM component model b, the calling frequency of the BIM component model c and the calling frequency of the BIM component model d according to the component calling frequency calculation formula. If the frequency of calling the BIM component model a < the frequency of calling the BIM component model b < the frequency of calling the BIM component model d < the frequency of calling the BIM component model e, the retrieval unit may display the component codes and the component names of the five BIM component models in a descending frame of the retrieval bar in order from high to low according to the frequency of calling.
When the user selects the BIM component model c, the retrieval unit sends the component code of the BIM component model c to the preview unit and the component attribute unit of the component calling module. The preview unit searches the BIM component model c in the component model storage module corresponding to the component calling module according to the component code of the BIM component model c, displays the BIM component model c in the model preview window, and a user can obtain models with different precision levels of the BIM component model c by checking the options of the precision levels. The component attribute unit searches for and obtains default attributes and default attribute data of the component model c in the data layer according to the component code of the BIM component model c, the default attributes and the default attribute data are displayed in a component attribute list, if a user considers that the default attribute data of the default attribute 5 does not meet actual requirements, the default attribute data corresponding to the attribute 5 can be changed, the component attribute unit receives a change value of the attribute 5, the change value of the attribute 5 is sent to the data layer 2, and the data layer 2 can store the change value of the attribute 5 as historical data of the attribute 5. The next time the user wants to change property 5, the historical data for property 5 may be displayed in a drop-down box in the default property data field for property 5 for selection by the user. After confirming that the information of the BIM component model is correct, the user can click a confirmation key to complete the calling of the BIM component model.
