3. Virtual simulation software for mechanical tr*ning safety education: This software is developed based on unity3d. The software adopts the form of three-dimensional roaming. The movement can be controlled by the keyboard and the direction of the lens 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 three-dimensional roaming screen uses arrows and footprints to prompt moving 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 three-dimensional 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 two types of fence heights and opening sizes). After entering, the GB23821-2009 "Safety distance to prevent the upper and lower limbs from touching the dangerous area for mechanical safety" requirements pops 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 picture and voice reminder receive mechanical injury, and return to the original position and conduct the next experiment. The last step is the correct approach.
B. The mechanical safety protection device experiment is divided into safety interlock switch, safety light curt*n, safety mat, safety laser scanner and other protection device experiments. The optional categories (safety input, safety control, safety output, other), manufacturer, product list (safety interlock switch, safety light curt*n, safety mat, safety laser scanner, safety controller, safety relay, safety fence). There is a blue flashing frame reminder at the installation location. The experimental process: 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 sound an alarm and the mechanical object will stop working. You can stop it by pressing the reset button on the electrical control box.
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. 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 obt*ns the total score and the score of each assessment point.
D. The software must be the same platform as a whole and shall not be displayed as a separate resource.
