Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering model building, and in particular to an electric power engineering construction method based on a BIM model. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. At the same time, it can be understood as power transmission and transformation expansion engineering. With the acceleration of urbanization, energy demand is growing. In order to ensure the normal operation of the city and the quality of life of residents, the power system plays a vital role in the city. During the construction of power projects, construction workers often need to strictly follow the construction drawings to make corresponding work arrangements, including material preparation. When preparing materials, the materials contained in the construction drawings often need to be manually identified and counted. The efficiency of material preparation is very low, and due to the large quantity and variety of materials, it is easy to miss or make mistakes when manually identifying and counting.

[0003] In view of the above technical problems, a system and method for collecting and analyzing materials information of power engineering projects based on a drawing group is disclosed in the announcement number CN114170616A, which can automatically extract and count the materials data in the power engineering construction drawings through image text recognition. Compared with manual recognition, the efficiency and accuracy of material statistics are greatly improved. The influence of interference factors in the recognition process is eliminated by preprocessing the power engineering construction drawings, and the accuracy of image text recognition is further improved by cutting the images of the power engineering construction drawings. The above patent also has the following shortcomings: in the prior art, the power construction process is carried out in reference to the design drawings, and then errors may still occur during the construction process due to problems with the construction process, so that the step-by-step construction cannot be carried out accurately and the construction process cannot be monitored in real time. Summary of the invention

[0004] The purpose of the present invention is to provide a power engineering construction method based on the BIM model, which has the advantage of realizing real-time monitoring of construction based on the BIM model, and realizes efficient and high-quality data conversion by setting up project basic data collection, BIM model construction, monitoring system setting, data display, data classification, calibration and correction, multi-dimensional calculation, etc., and uses the process flow to connect the operation mode in series to build a multi-channel, highly correlated system organizational structure, so as to achieve the effect of optimizing the process, improving the comprehensiveness of project monitoring, and accurately tracking the progress, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a power engineering construction method based on BIM model, comprising the following steps: Step 1: Collect basic project data on the bill of quantities, equipment specifications and installation locations in the construction project, then obtain a data set and build a BIM model through the data set; Step 2: Set up several monitoring nodes, alarm nodes and display nodes on the BIM model, and connect the BIM model to the monitoring system; Step 3: When the monitoring node detects an abnormal situation in the construction process, the alarm node notifies the construction personnel to take measures, and the display node displays the data during the monitoring process; Step 4: Classify, calibrate and correct the data after data display, and perform multi-dimensional calculations, and then display the processed data again.
