A three-dimensional layout method and device of railway signaling outdoor equipment based on BIM

Abstract

The invention discloses a three-dimensional layout method and device of railway signal outdoor equipment based on BIM, which can improve the accuracy and efficiency of the three-dimensional layout ofthe outdoor equipment in railway signal BIM design. The method comprises the following steps of: establishing a component three-dimensional model resource database; determining and storing the location parameters of each component in the component three-dimensional model resource library; setting reference points of each component in the component three-dimensional model resource library; importing the line centerline model and the mileage and height difference information into the target railway BIM project, and importing the civil engineering professional three-dimensional model as a reference; inputting the type, mileage and position parameters of the railway signaling outdoor equipment to be arranged, and determining the position of the placement datum point of the components in the civil engineering professional three-dimensional model of the target railway in single or batch according to the input parameters, thereby realizing the three-dimensional arrangement of the railway signaling outdoor equipment; Then import the three-dimensional models of other specialties to complete the model assembly.

Description

technical field [0001] The invention relates to the technical field of three-dimensional arrangement of outdoor railway signal equipment, in particular to a method and device for three-dimensional arrangement of outdoor railway signal equipment based on BIM. Background technique [0002] Building Information Modeling (Building Information Modeling, referred to as BIM) is a multi-dimensional model information integration technology developed on the basis of computer-aided design (CAD) and other technologies. In recent years, various railway design units have begun to vigorously develop BIM technology. [0003] At present, BIM software platforms commonly used in the railway industry include Bentley series software, Revit, Dassault, CATIA, etc. Using these software can realize part of the basic BIM design and application of railway signaling, such as three-dimensional modeling of components, manual arrangement of equipment, entity collision detection, etc. However, since thes...

Problems solved by technology

However, since these softwares are oriented to multiple majors (not only for railway signal majors), what they can provide at present is the common basic functions of each major. Requirements for Signal Practical Engineering Applications

[0004] For the 3D layout function of railway signal equipment, the currently commonly used BIM software can only provide manual placement function, but the biggest problem with manual placement of equipment is that it is difficult to grasp the accuracy of the placement position, and the manual placement method is extremely inefficient, and Bulk placement of multiple devices is not possible

In actual railway engineering, what needs to be tested is whether the equipment meets the requirements of railway building limits in the horizontal and vertical directions. Therefore, the existing BIM software functions cannot meet the actual collision detection requirements of railway signal professionals.
