I. Overview

The home appliance technology comprehensive tr--ning system This device integrates various commonly used home appliances and electrical control tr--ning programs for electromechanical, electric heating, and electromagnetic categories, which can meet the tr--ning and teaching goals of the corresponding courses of various schools. The device adopts a pendant -type modular structure. From power supply to electrical control pendant, pendant to physical models, a dedicated wire connection is used. The performance and specifications of the supporting parts are closely combined with the needs of tr--ning. Fully meet the requirements of tr--ning content.

 

2. Structure

  1. Style: This device shows the tr--ning module of various small appliances by simulating the three -dimensional form of the kitchen, which is convenient for students to learn more intuitively. The room is composed of steel mesh pore boards and steel -specific profiles. There are self -locking foot wheels, which are convenient to move and use. The surface of the device is sprayed with static electricity, the color is stable, the appearance is beautiful and generous, and it is not easy to retreat. The device is equipped with a dedicated power platform. The design height is the height of the person standing at the first -level human character ladder. It is safe and the user can feel the construction site environment. The width of the horizontal and bush is appropriate to simulate the steering layout of the on -site line. The mesh plate can be easy to remove. In order to facilitate the construction of the project, the steel frame imitation building partition is carefully designed with light steel keel with light steel keel, with pipe holes, using a fixed wire tube, and wearing a network pores. From time to time, you can use a wall to attract the wire to put into the bright bottom box. The device has a tr--ning platform. The countertop is made after forming a surface fireproof board. The substrate is 25mm thick E1 granular particle board; the body: use 18mm melamine jewelry surface E1 grade board, the other parts use 2mm thick high -quality PVC sealing strip, mechanical machinery Border sealing; tr--ning programs such as disassembling analysis of electronic fan, micro -computer control rice cookers, microwave oven, electronic disinfection cabinets, fully automatic washing machines commonly uses appliance structure, component identification detection, common typical f--lure analysis exclusion and other tr--ning items.

Each operation desk of the system has an independent component cabinet, which is convenient for the storage and installation of components, and is conducive to the convenience of teaching and tr--ning and use. By simulating the three -dimensional form of the kitchen, the tr--ning modules of various small appliances are displayed to facilitate students to learn more intuitively. They can complete the tr--ning content of various small appliances according to the actual teaching conditions of the school.

 

Machinery tr--ning security education virtual simulation software: This software is developed based on Unity3D. The software adopts the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with a safe distance experiment, security protection device experiment, safety protection design basic assessment. During the experiment, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the object shows a working radius. The experimental process is accompanied by a three -dimensional robot dialog box reminder.
