Description

BIM based integrated operation system for rail infrastructure life cycle management}

The present invention relates to a BIM-based integrated operating system for managing the railway infrastructure life cycle.

Building Information Modeling (BIM) refers to the process of virtually modeling a facility from planning, design, engineering (structure, facility, electricity, etc.), construction, maintenance, and disposal in a multidimensional virtual space.

This BIM method converts buildings into data to create numerical data and is a 3D-based design and modeling method that allows you to see 3D display effects. It generates data of the length connecting the start and end points of a line, rather than simple line and plane work. The area is data based on the closed surface, and volume data can be obtained by combining the length and area data.

In addition, the BIM method includes information on the shape information, attribute information, relationship, and topology of an object, so it is excellent in analysis, service linkage, and usability. In other words, BIM expresses each property of building objects such as walls, slabs, windows, doors, roofs, and stairs, recognizes the relationship between them, and can immediately reflect the changing elements of a building to the building design. Therefore, by using BIM, regardless of whether the building to be designed is structured or irregular, it is possible to integrate and utilize information at all stages through compatibility and sharing of data generated during building construction by project and process. .

Recently, attempts to apply BIM technology not only to the construction industry but also to the railway infrastructure business are increasing. However, the level of grafting and managing BIM technology to the railway infrastructure business is still in the development stage, so it is possible to check the application of BIM during the railway infrastructure business from the planning stage to the operation and maintenance stage, and to solve errors and problems. There are many difficulties in sharing and solving each other.

For example, it may be an input device such as a keyboard, mouse, or touch pen, and an output device such as a display.

Furthermore, the operation of the linear 4D simulation unit 110 is not limited to being performed by a manager, and may be automatically executed through deep learning or machine learning-based learning of an artificial intelligence model.

The first information input unit 111 includes a parametric model 111a and a BIM library 111b, and the parametric model 111a is a member of the railroad system through input of parameters (dimensions) for each member of the railroad system. Each parameter is set, and the BIM library 111b can build a BIM for each member of the railway system by setting the shape of each member of the railway system through input (or selection) of the shape of each member of the railway system.

The linear 4D model conversion unit 114 generates a linear 4D simulation using 3D modeling, schedule information, and location information. That is, the linear 4D simulation is generated by reflecting the schedule information and location information set in the second information input unit 113 to the 3D railway system model generated by the 3D model generator 112.

Here, the linear 4D simulation is a linear simulation because the 3D railway system includes a track (railway), which is a linear structure, and the linear 4D simulation is converted into a 4D simulation through the reflection of schedule information and location information in the 3D railway system model. .

After the design BIM information management unit 115 executes the linear 4D simulation generated by the linear 4D model conversion unit 114 at least once, the results of the linear 4D simulation are reflected in the design BIM information stored in the database server 150 Preferably, the result of the linear 4D simulation is transmitted to the database server 150.

Here, the result of the linear 4D simulation means whether the design of each railway system member is designed according to schedule information and location information on the linear 4D simulation, and the manager can determine the schedule information included in the schedule information through the linear 4D simulation. The construction site included in the location information can be reviewed while determining whether the members of the railway system are designed in the order of construction schedule.

In addition, when the linear 4D simulation is executed at least once, the design BIM information management unit 115 generates first image data for the linear 4D simulation in which the design of each railway system member proceeds in order of predetermined information, and the first From the image data, second image data for events (processes) from the start to the end of design of each railway system member are extracted.

In this way, separately generating and extracting the first image data and the second image data for the linear 4D simulation is a 3D railroad system including the member design process of the railroad system with the linear 4D simulation through the first image data by the manager. This is so that the model can be reviewed, and the process from the beginning to the end of the design of each railroad system can be closely reviewed through the second image data.

Meanwhile, as the design BIM information management unit 115 generates the first and second image data, it is preferable that the first and second image data of the linear 4D simulation as well as the result of the linear 4D simulation are additionally reflected in the design BIM information. .

The safety diagnosis unit 120 receives construction BIM information including data on the construction procedure of the railroad system from the database server 150, and then converts the construction BIM information into VR or AR content to determine whether the railroad construction site is safe. and provides information on the progress of the railroad construction site through the diagnosis of whether the railroad construction site is safe.

That is, the safety diagnosis unit 120 has a feature of expressing the safety of the railroad construction site based on VR or AR, and means applicable to devices or facilities for the construction of the railroad system at the railroad construction site (eg, AR-based of site vision).

Manages railroad construction sites and railroad completion sites.

Since the drone control used by the construction and completion management unit 130 and the lidar installed in the drone are common, a detailed description thereof will be omitted for convenience.

The maintenance unit 140 maintains the railway system by checking whether or not a member of the railway system is damaged or malfunctions based on the integrated BIM information received from the database server 150 .
