Experimental table: The experimental table is built by industrial standard aluminum profiles, and the surface of the profile is treated by electro-oxidation, which is beautiful and durable. The table top is made of high-density sheet, which is sturdy and beautiful in appearance; it has two large drawers for tools and materials. 4. The experimental project and main content: 1). Make students familiar with the working principle and structural composition of industrial common sidewalk escalators, and the structure and principle of low-voltage electrical appliances. 2). By analyzing the electrical schematic diagram, the students grasp the safety protection and working form of the elevator by means of schematic analysis; and through analysis and measurement, find out the location of the fault point and deeply understand the operating principle of the elevator. 3). Improve students' practical hands-on analysis skills and actually improve their skill operation level. 4). Through the analysis and elimination of the elevator failure, the cognition and understanding of the common faults of the elevator are completed. 5). Through the programming of the Mitsubishi PLC host, understand the programming principles and methods of the PLC program. 5. Escalator teaching simulation software The software uses 3DPDF virtual simulation technology, 3D PDF combines dynamic PDF documents of text, images, images, videos and forms (ie interactive PDF documents with 3D animation), including rich 3D data. The software interface is vivid and beautiful, easy to learn and use, can improve the interest of teachers and students, and deepen students' understanding and application of knowledge. Through three-dimensional disassembly animation, three-dimensional assembly animation, simulation disassembly and other methods, the software vividly demonstrates the disassembly and assembly process of the elevator ladder mechanism, truss structure, drive mainframe and other modules. The following functions can be implemented: 1). Virtual interactive disassembly animation, in the order of mechanical structure, each step has an animation and detailed disassembly text introduction. 2). The software can freely rotate, zoom, pan, hide, isolate, display, etc. the model, with rotation model, zoom model, mobile model, hidden selection, isolation selection, all display, full screen switching, etc. . 3). Software playback function: There are buttons for the first step, the previous step, the play all, the next step, the last step and so on. 4).
