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 mechanical safety protection design basic assessments. During the experiment, the three-dimensional 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 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 height and opening size). After entering, the GB23821-2009 "Safety distance to prevent the upper and lower limbs from touching the dangerous area" requirement pops up in front of the camera. Wrong demonstration: the experiment 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).

2. Software Features
The software is m*nly based on 3D visualization control technology, focusing on incorporating production tr*ning into the workplace environment, conforming to the characteristics of vocational education, and has good situational characteristics; the content comes from the typical production site of the occupation (type of work), focusing on the standardized tr*ning of the operation process, and providing drawings, production processes, industry specifications, the use of tools and equipment, safe production and other internship and tr*ning resources. Through dynamic interaction with the software, students can select machines, answer questions and other links, so that students can feel as if they are in the actual construction project, combining learning and practice.
The software adopts full 3D programming technology, 3D animation under fixed scenes and 2D programming technology to effectively compress data and occupy a small data space. After testing, the response time of the software does not exceed 1 second at most, and the running speed meets the standard. The continuous broadcast function is supported during the operation, and the interactive construction steps can be played continuously. The software is click-to-use, and the response speed is less than or equal to 1 second, which is convenient for teachers to expl*n the knowledge content synchronously during teaching and enables students to deepen their memory and consolidate their learning. The
system has strong interactivity, simple and convenient operation, and flexible and reliable use. The software has rich media means and reasonable application.
