Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited to these examples.

A full-automatic list mapping method based on a BIM system is disclosed, as shown in FIG. 1, and mainly comprises the following steps:

s100, establishing and storing a first association relation for reflecting the corresponding relation between the component and the code;

s200, establishing and storing second association relations for reflecting the corresponding relations between the BIM and each component and between each component and each sub-component;

s300, acquiring a BIM (building information modeling) model of a list code to be generated, and generating and storing component information and sub-component information corresponding to the BIM model based on the second incidence relation;

s400, generating a list code corresponding to the BIM model based on the first incidence relation.

In the step S100, the components include component information in the BIM model and corresponding sub-component information thereof, each component corresponds to a different code and a different coding rule, and the codes corresponding to the components are stored in a unified manner to form a rule base.

In detail, the step S100 further includes:

s101, importing and storing the coding rules of each component to form a rule base. The above-described importing method can be used to enter the relevant data in a form of downloading an EXCEL form template, for example.

S102, inputting component information in a setting template and searching a coding rule corresponding to the component information in the rule base. In practical applications, the setting template can be configured as the EXCEL form template as described above, and can also be configured as other interactive windows having a human-computer interaction interface and having a specific data link relation with the EXCEL form.

S1021, if the coding rule corresponding to the component information is stored in the rule base, coding and storing the component information based on the coding rule;

and S1022, if the rule base does not have the coding rule corresponding to the component information, prompting to manually input and maintain the coding rule to generate and store the code corresponding to the component information.

In the above steps S1021 and S1022, after the user inputs the component information, the system autonomously analyzes and retrieves the component information, searches the rule base, that is, whether the encoding rule corresponding to the component information already exists in the EXCEL table, and if not, prompts are made.

As shown in fig. 2, the step S101 further includes:

s1011, each bit code is divided into a plurality of groups according to a set rule. The EXCEL form template is mainly divided into groups such as item feature related attributes, quantity attributes and auxiliary attributes, wherein the groups respectively define different attributes of the component, and a user can add new attributes to the component by inserting columns.

S1012, establishing association relations between codes in each group and association relations between codes in each group; the incidence relation comprises a fixed corresponding relation and a set calculation formula. For example, in the embodiment of the present application, the data of the item feature related attribute may affect the attribute of the last three bits of the list after encoding, and different last three bit values may be generated in the table template according to the difference of the item feature related attributes of the first nine bits of the list corresponding to the component. The quantity attributes influence the engineering quantity of the component, the engineering quantity of the component can be displayed according to the formula calculation result, if no formula exists, the engineering quantity can be assigned according to the field content in the quantity attributes, if no quantity attributes exist, the engineering quantity can be directly calculated according to the number, and the corresponding engineering quantity of each component is assigned to be 1.

S1013, detecting the set group codes and the changes thereof, and generating codes of the set bits of the list codes according to the incidence relation;

in the embodiment of the application, the process of detecting the set group codes and the change of the set group codes is to import the EXCEL form template into the system after the EXCEL form template is perfected, and then the EXCEL form template is automatically compared by the system. After the importing is successful, the system can compare the front and the back of the table template, if the data is not changed, the prompt is not output, otherwise, the prompt is output.

In order to ensure that the codes in the rule base are not modified by errors, in the embodiment of the application, authority management is introduced to the modification of the rule base. The method specifically comprises the following steps:

a, setting code editing approval authority and data link;

b, detecting and responding to the code editing request or detecting the code change condition to generate an approval request;

and c, confirming the approval result, and fixing the code modification content if the approval is confirmed.

In the step a, the set code editing approval authority is included in the form template, the first nine list codes are allowed to be modified, after the first nine list codes are modified and approved, the first nine list codes in the first nine rule base are modified, the first nine list codes in the last three rule base are modified, and the maintained information of the last three bits, the project characteristic description and the like are kept unchanged.

In the step b, when the data in the form template is detected to be changed, an authority approval interface is automatically output, or the authority approval information is sent to a corresponding user terminal, so that the newly added data is approved.

In step S100, the first association relationship includes a data table and a set calculation formula or a mapping relationship between set cells therein, and if the component engineering quantity in the quantity attribute is displayed according to a formula calculation result.

And the rule base is preset with a data retrieval unit and is in data connection with a data interaction interface, and data global search is carried out based on user operation.

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

In step S400, as shown in fig. 3, the method further includes:

s401, generating a component list according to component information and sub-component information corresponding to the BIM model;

s402, searching component information or sub-component information which is not endowed with codes based on the component list;

s403, highlighting the component information or the sub-component information, and calling a coding editing interface corresponding to the component information or the sub-component information;

s404, establishing data connection between the coding editing interface and the rule base, and adding the coding rule corresponding to the sub-component information in the rule base based on the operation information acquired by the coding editing interface.

By the technical scheme, the component information or the sub-component information corresponding to the BIM can be screened when the list code is generated, and omission is avoided.

When a BIM model is input for list mapping, the model is selected and the list mapping is carried out on the model, and corresponding list codes are generated according to the rule base during the list mapping. If the coding rule corresponding to the member does not exist in the rule base, the codes of the set digit or the group are automatically generated according to the coding rule stored in the rule base, and then the rest codes are generated according to the incidence relation among the numbers of the coding codes, for example, the first nine bits of the list are generated firstly, and the last three bits are generated secondly. If the component can not find the corresponding coding rule in the rule base, a prompt interface is output, and the user completes the rule base. And (4) completing the rule base, then performing model mapping again, checking whether omission exists, and if not, storing the list codes.

In certain embodiments, unsuccessfully mapped components may be displayed in a graphical interface of the BIM model, for example, unsuccessfully mapped components may be displayed in a differentiated manner in a three-dimensional image of the BIM model.

The advantage of the scheme of the application lies in that the list items meeting the national standard are matched for each component in the BIM through the adoption of the special coding mapping rule and the special maintenance method, so that the automation operation of the components can be realized, the group price efficiency is improved, and the accuracy of the group price can be obviously improved.
