Therefore, it can be widely used in places with large and concentrated passenger flow, such as stations, docks, shopping malls, etc. This escalator equipment has transportation capabilities, and all transmission parts are made of high-quality metal parts, consistent with the actual escalator structure. The elevator electrical skills tr*ning and assessment experimental device is used for PLC electrical control teaching and assessment in electrical, automation and related majors in major universities, technical secondary schools, vocational schools, social electrician tr*ning, and county and city m*ntenance electrician appr*sal institutes (stations) . It is developed and can be used for classroom demonstrations, principle operations of elevator electrical control and experimental practice. Dozens of circuit faults are artificially and covertly set up in the practical tr*ning device. Students can analyze and judge faults with the help of schematic diagrams, and g*n a comprehensive and true understanding of elevator electrical faults and their troubleshooting. It is an ideal device for skill tr*ning and assessment, and the teaching effect is real and significant. 2. Technical parameters 1.

The model in the comprehensive integrated vocational skills tr*ning virtual simulation system software can be rotated 360°, enlarged, reduced, and panned, and is equipped with universal interactive buttons: return, home page, and help. There are prompts during all virtual simulation tasks, and the software automatically checks the box after completing a task. There are experimental tasks 1 and basic three-dimensional above the tool library. ( When the model is rotated , the XYZ space coordinate icon automatically follows the rotation.) A. Plane and three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - building models (drag and drop in the tool library The model is put into the three-projection plane system, and the projection is automatically displayed. There will be a prompt when the selection is wrong) - Change the posture (change by clicking the up, down, left and right arrows) - Select the projection (enter the answer interface, select the three-dimensional projection map completed at this time among the 6 items) ) B. Cutting three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - building the model (drag the model in the tool library into the three-projection plane system, and automatically display the projection) - marking the projection situation (as a three-dimensional projection icon Determine, select the corresponding label symbol in the 14 blank columns) C. Intersecting three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - digging holes (select any digging model, at this time, you will be able to dig holes in the XYZ space coordinates Select any surface, the model will be switched at the same time, and a coordinate slider will appear. According to the displacement of the slider, the model will appear with a corresponding section plane) - aperture change (select 1-4 apertures) - rear through hole - select projection (enter the answer interface) , select the three-dimensional projection image completed at this time among the 8 items) 2.
