Background
Under the large trend of informatization and industrialization in the building industry, BIM technology is leading to the optimization and upgrading of a building mode due to the outstanding advantages of optimality, simulation, visualization, coordination and the like, and BIM application gradually becomes the main stream in the building industry; BIM can help project team understand the standards and regulations of complex space by analyzing the space in the building planning stage, thereby saving time and providing possibility of more value-added activities for team. Particularly, when customers discuss requirements, select and analyze optimal schemes, critical decisions can be made by means of BIM and related analysis data; the application result of the BIM in the building planning stage also helps an architect to check whether the preliminary design meets the requirements of owners at any time in the building design stage, and whether the preliminary design meets the design basis obtained in the building planning stage, and the huge waste of modification design when unqualified is found in the detailed diagram design stage in the future is greatly reduced through the continuous information transmission or traceability of the BIM;
however, in practical application, it is generally found that, due to different levels of engineers, the BIM database is not reasonably utilized in the construction of the early stage of the project, so that the project time is saved, and when the model information is inconsistent with the field information and needs to be modified, no safe platform is available for processing and storing the data so as to prevent interference to the historical safe data; meanwhile, the BIM engineer and the field engineer communicate in real time in different places in the model, so that the BIM engineer and the field engineer have the limitation that the two parties can not immediately use the same window to rotate the model to confirm that the discussion positions are identical, the difficulty degree of modifying the characteristics can not be determined, and the problems of accurate positioning and quick solution can not be realized.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the present invention provides the following technical solutions: a visual management method for engineering implementation based on BIM technology comprises the following analysis steps:
step S1: acquiring an engineering database recorded by BIM technology, wherein the engineering database refers to data recorded from the process of constructing a model of an original space structure by using the BIM technology to the process of finishing engineering by taking the original space structure as a unit; the engineering is completed, namely the BIM construction model is mapped onto the original space structure to form an actual engineering structure; splitting all model mapping projects recorded in the project database and outputting a basic underlying framework;

In step S1, all model mapping projects recorded in the project database are split and a basic underlying architecture is output, and the method comprises the following analysis steps:
the model mapping project refers to the process of correspondingly implementing the BIM structure model on the actual space structure, and the splitting refers to the fact that each project framework of the project database for planning construction is a splitting unit according to the finishing sequence of the actual construction process; constructing a structure data pair A, A { a } corresponding to the splitting unit 1 →a 2 (wherein a) 1 Representing a BIM model architecture corresponding to the splitting unit, and a2 represents an actual engineering architecture corresponding to the splitting unit;
extracting all structure data pairs contained in all projects recorded in the project database;
sequentially comparing BIM model architecture and actual engineering architecture of the structure data pairs in different projects, taking any structure data pair as a target structure data pair, extracting the number m of projects to which other structure data pairs in the engineering database which are completely the same as the target structure data pair belong, and utilizing the formula: f=m/M, calculating the universality ratio f of any structural data pair; wherein M represents the total number of recorded projects in the project database;
and extracting a target structure data pair corresponding to the maximum value max (f) of the pervasive ratio as a basic infrastructure.
In the engineering implementation recording process, structures of different engineering have the same points, because the analysis and comparison process of historical engineering is rarely carried out in the existing construction process, and meanwhile, analysis is also a relatively time-consuming engineering, engineers prefer to formulate a BIM model from scratch and also do not want to search for directly utilizing the existing model, and the application selects a basic framework suitable for most engineering modeling and an alternative combined framework by extracting a large amount of engineering data, so that the time cost of the engineer on structural design is saved, BIM technology is utilized more comprehensively and intelligently, and the universality of the BIM model is improved.
Step S2 comprises the following analysis steps:
acquiring an engineering framework with a connection relation with a basic underlying framework, wherein the connection relation comprises a first connection relation and a second connection relation;
the first connection relationship refers to a connection relationship which is connected with the basic underlying framework in a space position and does not contain the basic underlying framework;
the second connection relationship refers to a connection relationship of a newly added architecture on the basic underlying architecture;
constructing an engineering tree with a first connection relation or a second connection relation corresponding to the engineering architecture as a child node by taking the basic underlying architecture as a root node; matching and combining different engineering trees and outputting a combined set which comprises all engineering trees as an engineering framework; the matching combination refers to that a first connection relation or a second connection relation exists between engineering frameworks contained in the combined engineering tree.
The engineering tree is constructed to clearly and rapidly extract a model diagram which can be utilized in the BIM model architecture.
The engineering architecture in the application is based on the spatial physical structure relation in the BIM, and does not relate to the attribute information about the structure, so that when different engineering needs to utilize the engineering tree, the attribute information contained in the architecture is not needed to be considered, and only the corresponding structure is needed to be extracted. And (3) if in the construction stage of the actual pre-buried pipeline, the water supply and drainage BIM model is directly positioned on the field. Guiding on-site slotting through corresponding scribing on the on-site by pipeline trend of the BIM; in this process, the drainage BIM model may be a root node, and the corresponding child node is a pipeline configured in the BIM model, belongs to the child node, and is a second connection relationship.
In step S3, the relevant values of the abnormal event and all the completed engineering structures before the abnormal event occurs are analyzed and extracted, which includes the following analysis steps:
marking the engineering architecture in the engineering architecture combination corresponding to the abnormal event as an objective architecture to be analyzed, and obtaining the number n of the objective architecture to be analyzed existing in the engineering tree 1 The engineering architecture recorded before the implementation of the target architecture to be analyzed is the investigation architecture, the investigation architecture changed when the target architecture to be analyzed carries out abnormal event processing is extracted to be the first investigation architecture, and the change times d corresponding to the first investigation architecture are marked 1 Using the formula:
G=k 1 [(n 1 /N)+(d 1 /D)]
k 1 =u 1 /u 2
calculating the association value G of the abnormal event and all the completed engineering structures before the abnormal event occurs; n represents the total number of engineering trees, D represents the total number of changes in an abnormal event;
wherein k is 1 Representing the first correlation coefficient, k 2 Representing a second correlation coefficient;
u 1 represents n 1 The target architecture to be analyzed in each engineering tree is the number of root nodes in the engineering tree, u 2 Represents n 1 The target architecture to be analyzed in each engineering tree is the number of sub-nodes in the engineering tree.
The method comprises the steps that the node relation of an engineering tree to which a target architecture to be analyzed belongs is confirmed to consider the influence degree of the target architecture to be analyzed in an abnormal event, and the influence degree is generally larger than that of a child node when the target architecture to be analyzed is a root node;
the analysis is based on the abnormal events in the engineering framework combination, because the engineering framework combination can be applied to other engineering, and the analysis of the abnormal events can be the early warning response of the subsequent implementation engineering when the engineering is executed to the same engineering link.
Step S5 comprises the following analysis steps:
extracting the feature names of the engineering architecture corresponding to the modified data;
recording the regulation times y of the feature names in the BIM model architecture marked by the field engineers 1 The regulation and control refers to clicking, amplifying and rotating operations of a field engineer on the BIM model framework; acquiring the regulation and control times y of BIM engineers corresponding to the same feature name 2 ；
Using the formula:
Z=｜y 1 -y 2 ｜(y 1 /Y)
calculating a first regulating value Z corresponding to the feature name; wherein Y represents the total number of times of regulation and control of field engineers corresponding to all feature names;
extracting all feature names and first regulating and controlling values corresponding to the feature names of the abnormal event records, sequencing the feature names according to the sequence from the higher to the lower of the corresponding first regulating and controlling values to generate priorities, and outputting corresponding early warning signals.
Because the precondition of the application is that engineers communicate in different places, the site engineers do not have the problems existing in the BIM engineers in quick and professional positioning actual space structure, deviation on BIM model operation exists, if the engineering architecture is simple in structure, the influence on the communication of the engineering architecture and the BIM engineers is small, and if the engineering architecture is difficult, larger deviation is generated; therefore, the modification difficulty of the feature structure to be modified can be judged by analyzing the deviation of the BIM model control;
the method and the system do not define the specific content of the modified data, only analyze the difficulty of the modified data, and sort the priority after extracting the feature names of the engineering frameworks corresponding to the modified data, so that when new construction projects exist and any engineering framework in the engineering framework combination set can be utilized, early warning is carried out on the framework features of the possible abnormal event, and after the problem occurs, detailed and proper data analysis and prompt are carried out on the different framework features according to the priority.
Recording modifications of the modification data as feature name 1, feature name 2, and feature name 3 in the abnormal event;
