1. Overall Specifications
The system uses computer simulation technology and 3D simulation technology to construct virtual working scenes of control centers, stations (centralized stations and non-centralized stations), depots
The system consists of three major parts: teaching, tr*ning and examination systems.
The teaching system constructs virtual working scenes of control centers, stations (centralized stations and non-centralized stations), depots, parking lots and tr*ns, and provides teaching functions for the standardized operation of driving in normal operation scenarios such as before, during and after operation for driving dispatchers, depot operation attendants/signal tower attendants, station attendants, and tr*n drivers in the urban r*l transit control center through plane and 3D methods combined with multimedia.
The tr*ning system is in the virtual control center, station (centralized station and non-centralized station), depot, parking lot and tr*n working scenes. According to the operation process of the driving position before, during and after operation, the tr*ning is carried out in groups, each of which includes the control center, depot, station and tr*n. The tr*ning is carried out online without affecting each other.
The examination system includes an examination module and an examination management module.
The examination system should include objective theory questions and operational questions, and can be automatically scored.
The examination management module can manage the question bank (operation questions, objective theory questions), paper bank management, candidate management, paper distribution, candidate scores in the form of individuals and classes, and export the corresponding results to EXCEL reports. Teachers should be able to edit and modify the standard answers to operational questions and theoretical questions.

Virtual simulation teaching system

Virtual simulation software for mechanical tr*ning safety education: This software is developed based on unity3d. The software adopts the form of 3D roaming. The movement can be controlled by the keyboard and the direction of the camera can be controlled by the mouse. There are mechanical safety distance experiments, mechanical safety protection device experiments, and basic assessments of mechanical safety protection design. During the experiment, the 3D roaming screen uses arrows and footprints to prompt movement to the experimental position. The circle around the mechanical object shows the working radius. The experimental process is accompanied by a dialog box reminder of the 3D robot.
A. The content of the mechanical safety distance experiment includes the safety distance experiment to prevent the upper and lower limbs from touching the dangerous area (divided into 2 types of fence heights and opening sizes). After choosing to enter, the GB23821-2009 "Safety Distance for Mechanical Safety to Prevent Upper and Lower Limbs from Touching Dangerous Areas" requirements pop up in front of the camera. Wrong demonstration: The experimental process is that after the human body enters the working radius of the mechanical object and is injured, the bloody screen and voice reminders are received. Mechanical injury, and then return to the original position and conduct the next experiment. The last step is the correct approach.
B. Mechanical safety protection device experiments are divided into safety interlock switches, safety light curt*ns, safety mats, safety laser scanners and other protection device experiments. Optional categories (safety input, safety control, safety output, other), manufacturers, product lists (safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, safety fences). The installation location has a blue flashing frame reminder. The experimental process is: select the safety fence and install it, select the safety interlock switch (or select the safety light curt*n, safety mat, safety laser scanner) and install it, select the safety controller and install it to the electrical control box, select the safety relay and install it to the electrical control box, and click the start button on the electrical control box. If you enter the dangerous area, the system will prompt an alarm sound, and the mechanical object will stop working. Select the reset button on the electrical control box to stop.
C. The basic assessment of mechanical safety protection design requires the completion of the installation of the mechanical safety system, the correct installation of safety guardr*ls, safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, 24V power supplies, signal lights and emergency stop buttons. The assessment is divided into ten assessment points, some of which have three options, which are freely selected by students. After the final 10 assessment points are selected, submit for confirmation, and the system automatically obt*ns the total score and the score of each assessment point.
D. The software must be on the same platform as a whole and must not be presented as a separate resource.
E. At the same time, the VR installation package of this software is provided to customers to facilitate users to expand it into VR experiments. VR equipment and software installation and debugging do not need to be provided.

Secondary unfolded cylindrical gear reducer: After entering the software, the content will be played in the form of video. The video content should include: part name (scan the QR code to see the part name), disassembly demonstration (including disassembly, assembly), virtual disassembly (including the whole, low-speed shaft, medium-speed shaft, high-speed shaft, box cover, box seat)
Bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, first-level cylindrical gear reducer: click to enter and automatically jump to the edrawings interface. The models are all three-dimensional models . By clicking on the parts to display the part name, you can rotate 360° in all directions, zoom in, zoom out, and translate. At the same time, you can use the move parts function to disassemble and assemble the entire reducer. At the same time, you can select the home button to return to the original state of the reducer. The bevel gear reducer and the first-level cylindrical gear reducer have added the function of inserting cross sections, and the cross sections can be freely dragged to observe the internal structure of the reducer.

The 3D scenes can be rotated 360°, enlarged, reduced, and translated.
3. Actual operation: The 3D parts are neatly placed on the desktop. Students manually select the corresponding parts and move them to the shaft system structure. The parts can be installed only when the placement order and position are correct. There is a restart button to facilitate students to repeat the virtual experiment.

When the mouse moves to a cert*n part position, the part is automatically enlarged and the part name is displayed. The software automatically completes the disassembly and assembly of the shaft system structure. When using the decomposition observation button, the three-dimensional model of the crankcase or valve system automatically displays an exploded view, which can be rotated 360°, enlarged, reduced, and translated.
2. The three-dimensional parts of the virtual assembly of the crankcase and the virtual assembly of the valve system are neatly placed on the desktop. Students manually select the corresponding parts and move them to the mechanism. The parts can only be installed when the placement order and position are correct. There is a restart button to facilitate students to repeat the virtual experiment. When the mouse moves to the position of cert*n parts, the name of the part is automatically displayed.
