Virtual simulation technology innovates the practical training model of vocational education skills. The VR virtual simulation solution of building blocks and easy-to-build subway tracks helps immersive rail transit teaching.

With the rapid development of science and technology, rail transit has become an important part of many urban transportation systems. Therefore, the demand for subway drivers is also increasing. However, there are certain problems in the traditional teaching methods of subway driving in various vocational schools, such as limited training venues, the need to spend a lot of time and money on the construction of subway driving training bases, and the teaching is difficult to meet the individual needs of students.

Virtual simulation technology has natural advantages in the field of vocational education skills training. In the field of professional training, especially in subway driving training, scene restoration, practical training and safety are highly valued. Virtual simulation technology is used to create a subway driving simulation training system, which 1:1 restores the track environment, station equipment, and environment during subway driving. The pictures are realistic and deeply immersive. On the one hand, it can save teaching costs; on the other hand, students can perform repeated practical operations many times and master skills proficiently in a highly simulated and highly immersive environment; at the same time, it can also ensure that the practical training environment is safe and reliable. The use of virtual simulation technology for training is very suitable for practical subway driving training in various vocational schools.

Domestic full-stack 3D digital solution provider Building Blocks Yida uses 3D modeling, virtual simulation and other technologies, combined with VR/AR equipment, to create a vocational school subway VR virtual simulation operation teaching and training with integrated software and hardware operation The system can reproduce the train operating environment and simulate the operation of various systems in the subway station. It can provide safe and reliable full-process subway virtual practical training technical support for subway rail transit teaching in vocational colleges and help cultivate professional talents.

Take the subway station operation monitoring simulation training system built by Jiuluoyida for a vocational college as an example. The subway station operation monitoring virtual simulation system constructs a full scene of a typical subway platform, including platform equipment, rails, and trains. , catenary and various equipment in the subway station, etc., 1:1 truly restores the overall structure of the subway platform. At the monitoring system level, two levels are set up: platform monitoring and equipment monitoring. The monitoring content includes ticket vending machines, gates, customer service centers, etc., and finally builds a subway station operation system that contains complete internal logical control relationships. Through VR equipment, large-screen projection, etc., students can either have independent cognitive equipment or jointly conduct multi-role virtual training of trains entering the station, so as to better understand the operation of the subway platform and improve their professional skills.

High-precision 3D modeling of subway stations, bringing high-fidelity and deep immersion

The subway station operation monitoring virtual simulation system created by Bricks and Blocks collects information from the real subway platform and conducts 3D modeling to integrate the entire subway station platform, trains, and basic equipment and operation monitoring equipment within the platform. The image is 3D modeled, so that the entire subway station operation system is displayed in the form of a 3D three-dimensional scene. The picture strives to be highly realistic and visually bring an immersive look and feel.

In the 3D scene, viewers can freely rotate, zoom out, and push in through mouse operations, which facilitates students to learn the equipment in the subway station and walk in the scene in a first-person manner to gain a panoramic view of the entire platform and various elements in the station. Browse by region and device. In the subway station, users can quickly locate a point to go where they want to go, and set the current point as the operating rotation point to rotate and zoom the entire 3D scene. It is convenient for students to quickly learn and understand the subway environment system.

Hierarchical design, multi-person and multi-role joint operation experiments to improve training efficiency

The subway station operation monitoring virtual simulation system created by Building Blocks integrates the principles of subway operation control for interactive design. It adopts a hierarchical layout and is divided into functional areas for operation and management, making it convenient for students to learn and experience.

From the perspective of the basic environment and equipment of the platform, the design is divided into two layers of navigation; the first layer of navigation mainly allows students to understand and familiarize themselves with the entire platform scene and train operation conditions; the second layer of navigation mainly displays The entire scene of the subway hall and various equipment and functional areas in the hall.

In the simulation of the entire subway station monitoring system, it is divided into two levels: platform monitoring and equipment monitoring. The system can dynamically simulate the process of trains entering and exiting the subway station and the operating conditions of the equipment in the station through interactive simulation. Students can control the equipment in the subway station through interactive operations, and strengthen their learning and monitoring of the operating principles and operations of trains and equipment in the station. In subway stations, 3D equipment mainly covers gates, customer service centers, ticket vending machines, and dispatching consoles.

Through the 3D space, integrating professional subway operation control principles, and combining with interactive operations, students can strengthen their understanding of subway trains and station operation monitoring, better serve teaching, and improve the professionalism of talents.

This set of subway station operation monitoring virtual simulation system created by Building Blocks Yidai combines 3D virtual technology with the real environment. The strong immersion and animation demonstration effect are very attractive, and it is easy to operate, professional, and Openness, maintainability, scalability and other characteristics. The biggest feature of the system is that it is not limited by time and space, can be divided into roles, can be operated by a single person or multiple people, prompts important teaching points, simulates reality, is safe and reliable, and saves costs.

Currently, in addition to providing students with more realistic, effective and personalized teaching and training methods in subway driving professional teaching, VR virtual simulation technology can also be applied in other transportation training fields such as car driving training. Building Blocks Yida uses 3D digitization, virtual reality technology, etc. to establish a virtual simulation system for operation monitoring of large-scale subway stations. The professional virtual simulation training solutions created for various vocational colleges can help various colleges reduce costs and increase growth in teaching and training. Effectively, improve students' professional quality and employability, and enhance the school's brand influence.
