Detailed ways

The present application will be further described in detail below with reference to the examples and figures, but the embodiments of the present invention are not limited thereto.

A fully automatic mapping method for inventory based on BIM system, as shown in Figure 1, mainly includes the following steps:

S100. Establish and store a first association relationship for reflecting the correspondence between components and codes;

S200, establishing and storing a second association relationship for reflecting the corresponding relationship between the BIM model and each component, and between each component and each sub-component;

S300. Acquire the BIM model coded by the list to be generated, generate and store component information and sub-component information corresponding to the BIM model based on the second association relationship;

S400. Generate a checklist code corresponding to the BIM model based on the first association relationship.

In the above step S100, the components include component information in the BIM model and their corresponding sub-component information, and each component corresponds to different codes and coding rules, and the codes corresponding to the above components are uniformly stored to form a rule base. In the embodiment of this application Among them, the above-mentioned rule base is stored based on a data table, such as an EXCEL table.

In detail, the above step S100 further includes:

S101. Import and store coding rules of each component to form a rule base. The above import method can be used to input relevant data by downloading the EXCEL form template, for example.

S102. Input the component information in the setting template and search the coding rule corresponding to the component information in the rule base. In practical applications, the above-mentioned setting template can be configured as the above-mentioned EXCEL form template, and can also be configured as another interactive window with a human-computer interaction interface and a specific data link relationship with the EXCEL form.

S1021. If the encoding rule corresponding to the component information is stored in the rule base, encode and store the component information based on the encoding rule;

S1022. If there is no encoding rule corresponding to the component information in the rule base, prompt to manually input and maintain the encoding rule to generate and store the encoding corresponding to the component information.

In the above steps S1021 and S1022, after the user inputs the component information, the system independently analyzes and retrieves the above component information, searches the rule base, that is, whether there is already a coding rule corresponding to the component information in the EXCEL table, and if not, prompts.

As shown in Figure 2, the above step S101 further includes:

S1011. Divide the codes of each bit into multiple groups according to the set rules. The EXCEL form template is mainly divided into groups such as "item feature-related attributes", "output attributes", and "auxiliary attributes". The above groups define different attributes of components. Users can add new components to components by inserting columns properties.

S1012. Establish an association relationship between codes in each group and an association relationship between codes in each group; wherein, the association relationship includes a fixed correspondence and a set calculation formula. For example, in the embodiment of this application, the data of the attributes related to the item characteristics will affect the attributes of the last three digits of the list code, and the table template will generate different values of the last three digits according to the different attributes related to the item characteristics of the components corresponding to the first nine digits of the list. The output attribute affects the engineering quantity of the component. The component engineering quantity will be displayed according to the calculation result of the formula. If there is no formula, the engineering quantity will be assigned according to the field content in the "output attribute". If there is no "output attribute", it will be The engineering quantity is directly calculated according to the number, and the corresponding engineering quantity of each component is assigned a value of 1.

S1013, detecting the set group code and its change, and generating the code with the number of set digits of the list code according to the above association relationship;

In the embodiment of the present application, the above-mentioned process of detecting and setting group codes and their changes is to import the EXCEL form template into the system after perfecting the EXCEL form template, and then the system automatically compares and completes it. After the import is successful, the system will compare the form template before and after. If there is no change in the data, no prompt will be output, otherwise, a reminder will be output.

In order to ensure that the codes in the rule base will not be wrongly modified, in the embodiment of the present application, authority management is introduced for the modification of the rule base. Specifically include:

a. Set code editing approval authority and data link;

b. Detect and respond to coding editing requests, or detect coding changes, and generate approval requests;

c. Confirm the approval result, and if the approval is confirmed, fix the code to modify the content.

In the above step a, setting the code editing and approval authority includes in the form template, allowing the modification of the first nine list codes. After the modification of the first nine list codes and approval is passed, in addition to modifying the first nine list codes in the first nine rule bases , will also modify the first nine list codes in the last three digits rule base, and the maintained information such as the last three digits and project feature description will remain unchanged.

In the above step b, when it is detected that the data in the form template has changed, the permission approval interface is automatically output, or the above permission approval information is sent to the corresponding user terminal, so as to approve the newly added data.

In step S100, the first association relationship includes a data table and the setting calculation formula or mapping relationship between the setting cells. For example, the component engineering quantity in the output attribute is displayed according to the calculation result of the formula.

A data retrieval unit is preset in the rule base and is connected to a data interaction interface for data global search based on user operations.

In the above step S200, the second association relationship is mainly a "contains" relationship, that is, a BIM model is transformed into a tree data structure, and each component and sub-component forms the BIM model itself.

In the above step S400, as shown in FIG. 3 , it also includes:

S401, generating a component list according to component information and sub-component information corresponding to the BIM model;

S402. Search for component information or sub-component information that has not been coded based on the above component list;

S403. Highlight the component information or sub-component information, and call the code editing interface corresponding to the component information or sub-component information;

S404. Establish a data connection between the coding editing interface and the rule base, and add coding rules corresponding to the sub-component information to the rule base based on the operation information acquired by the coding editing interface.

Through the above technical solution, the component information or sub-component information corresponding to the BIM model can be screened when the list code is generated to avoid omission.

When inputting a BIM model for checklist mapping, select the model and perform checklist mapping for the model. During checklist mapping, the corresponding checklist code will be generated according to the rule base. If there is no coding rule corresponding to the component in the rule base, the code of the set digit or group will be automatically generated according to the coding rules stored in the rule base, and then the remaining code will be generated according to the relationship between the code digits , such as first generating the first nine digits of the list, and then generating the last three digits. If the component cannot find the corresponding coding rules in the rule base, a prompt interface will be output, and the user can complete the rule base. After perfecting the rule base, perform model mapping again and check whether there are any omissions. If there is no omission, save the above list code.

In a specific implementation, the components that have not been successfully mapped can be displayed on the graphical interface of the BIM model, for example, the colors of the components that have not been successfully mapped can be displayed in a differentiated manner in the three-dimensional image of the BIM model.

The advantage of this application scheme is that, by adopting special coding mapping rules and maintenance methods, it is possible to match each component in the BIM model with a list item that meets the national standard, which can not only realize the automatic operation of components, improve the efficiency of price assembly, but also significantly improve The accuracy of the pricing.
