(9) 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 keyboard and the direction of the camera can be controlled by mouse. It has mechanical safety distance experiment, mechanical safety protection device experiment and mechanical safety protection design basic assessment. During the experiment, the 3D roaming screen uses arrows and footprints to prompt to move 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 (with 2 types of fence height and opening size). After entering, the requirements of GB23821-2009 "Safety Distance for Mechanical Safety to Prevent Upper and Lower Limbs from Touching Dangerous Areas" will 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 reminder are received. The machine is injured, and it returns to the original position and conducts 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 installation of the mechanical safety system to be completed, and the safety guardr*l, safety interlock switch, safety light curt*n, safety mat, safety laser scanner, safety controller, safety relay, 24V power supply, signal light and emergency stop button to be correctly installed. The assessment is divided into ten assessment points, and some assessment points have three options, which are freely selected by students. After the final 10 assessment points are selected, submit for confirmation, and the system automatically calculates 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 displayed as a separate resource.
