Referring to fig. 1, the present application proposes a system management method of BIM, including:
s1: acquiring an item tag of a target BIM system to be constructed;
s2: obtaining a similar system from a preset BIM system database according to the item label;
s3: extracting application points from the similar system;
s4: constructing a directed ring graph according to the interrelation of each application point in the similar system; wherein each node in the directed graph is formed by one application point;
s5: inputting the directed ring graph into a long-term and short-term memory network model to obtain a system code;
s6: inputting the system codes and the item labels into a long-term and short-term memory network decoder to obtain a system architecture; the long-period memory network model and the long-period memory network decoder are trained by taking a plurality of directed cyclic graphs and corresponding item labels as inputs and taking the corresponding system architecture as output;
s7: downloading a template file corresponding to the system architecture to form the target BIM system.
As described in step S1, the project label of the target BIM system to be constructed is obtained, where the project label may be one or more of a project type, an engineering stage, an engineering scale, a geographical location, a related industry or department, a technical requirement, and a regulatory dependency, and the project label may be extracted according to project information or manually.
And step S2, obtaining similar systems from a preset BIM system database according to the item labels. The preset BIM system database is a preset system database, and is a BIM system formed by related projects in the past, namely a system which can be used normally, and because the compatibility among all application points and the cooperative relationship among all application points are considered in the prior system, the problem of the problem is not needed to be worried about at the moment, the corresponding similar system can be directly obtained, and particularly, the systems in the preset BIM system database all have corresponding project labels, and the similar system can be obtained by selecting according to the similarity of the project labels.
As described in step S3, the application point is a module in the system, which has a certain function, and the data connection between the modules can be established, so that the similar system contains a plurality of application points, and the extraction can be directly performed, so that other specific data do not need to be acquired.
As described in step S4 above, a directed graph of loops is constructed from the correlations of the individual application points in the similar system. Each node in the directed ring graph is composed of an application point, and a directed ring graph is built for all application points, so that the transition probability from the application point A to the application point B can be calculated, wherein if a Markov chain is divided into m states, historical data is converted into a sequence composed of the m states. From any one state, one of states 1, 2, … …, m must occur after any one transition, and transitions between such states are referred to as transition probabilities.

And finally, all the generated output results are spliced in sequence to form a system architecture, so that the generated architecture has application points corresponding to the project labels.
And step S7, downloading the template file corresponding to the system architecture to form the target BIM system. Each application point is provided with a corresponding template, some application points possibly comprise templates of various different types, the templates can be pre-downloaded to obtain a temporary BIM system, then compatibility of each application point is detected, each template is replaced until each application point is compatible, and a final template BIM system is formed, so that the corresponding BIM system is built according to project information, the BIM system is built efficiently, development cost of the BIM system is reduced greatly, and fine management of BIM projects is realized.

s203: according to the formulaCalculating a similarity value between a label vector and a pre-stored vector of each system in a preset BIM system database, wherein A represents the pre-stored vector corresponding to each system in the preset BIM database, and B represents the label vector;
s204: and selecting the similar system according to the magnitude of the similar value.
As described in the above steps S201 to S204, the item label is vectorized to obtain a label vector, and the multidimensional coordinates of the label vector are obtained to facilitate subsequent calculation. The item tags may be vectorized by the Google word2vec tool. According to the formulaCalculating the similarity value between the label vector and the pre-stored vector, when the label vector is similar to the pre-stored vectorThe smaller the value is, the less the tag vector is considered to be matched with the pre-stored vector of the system, and when the similarity value is larger, the more the tag vector is considered to be matched with the pre-stored vector of the system, and then the pre-stored vector of the similar system is selected according to the magnitude of the similarity value.
In one embodiment, the step S6 of inputting the system code and the item tag into a long-short-term memory network decoder to obtain a system architecture includes:
s601: splitting the system code into a plurality of subcodes in sequence;
s602: sequentially inputting the subcodes into a preset decoder according to the sequence for decoding; the operation of the current encoding and decoding is that a hidden layer in the last encoding and decoding process, the item label and the current subcode are input into a preset decoder to obtain a decoding result of the current subcode;
s603: and splicing all decoding results in sequence to obtain the system architecture.

1. hidden layer state characteristics at the previous time t-1;
2. vector features of the output result at the previous time t-1;
3. user input features (item tags).
The long-short-term memory network decoder has the 3 inputs at each moment, and the output is the output result of predicting the current moment, and the output result is also used as the input of the next moment. And finally, all the generated output results are spliced in sequence to form a system architecture, so that the generated architecture has application points corresponding to the project labels.

s803: if the detection result is normal, judging that the target BIM system meets the requirements.
As described in the above steps S801 to S803, the compatibility detection of the target BIM system is achieved, and because there is a possibility of incompatibility between the template files acquired by each application point, analog data needs to be acquired for detection, where the analog data is preset by related personnel, and the corresponding prediction detection result is preset, and when the actual detection result matches with the prediction detection result, it can be determined that the target BIM system meets the requirement, otherwise, fine adjustment, such as changing the template, needs to be performed again on the data of each application point until the target BIM system meets the requirement.
In one embodiment, the step S4 of constructing a directed ring graph according to the interrelationship between the application points in the similar system includes:
s401: acquiring the data transmission times among the application points of the similar system;
s402: taking the duty ratio of the data transmission times as the interrelation between the application points;
s403: and establishing the directed ring graph based on the interrelationships.
As described in the above steps S401 to S403, the establishment of the directed ring graph is realized, and because the relationship between the application points can be reflected by the data interaction, the data transmission times are used as the relationship between the application points, and the directed ring graph is established according to the relationship, so that the directed ring graph also includes the data interaction relationship between the application points, and the system architecture of the subsequent production can be more fit with the requirement of the project, and the final target BIM system is better.
