It has a solid structure and a rectangular shape. It is beautiful and elegant. There are two large drawers for placing tools and materials. The tabletop is used to install the power control panel and provide a spacious and comfortable work surface. The tr*ning table is also equipped with four universal wheels and four fixed adjustment mechanisms for easy movement and fixation.
(IV) Simulation system
Virtual simulation system for electricity safety and electric shock first *d: The software uses a combination of two-dimensional and three-dimensional virtual images to teach students electricity safety and first *d methods. The software has single-phase electric shock, two-phase electric shock, step electric shock, low-voltage electric shock first *d, high-voltage electric shock first *d, artificial respiration rescue method, hand-holding breathing rescue method, chest compression rescue method and other principle explanations and teaching. Single-phase electric shock is divided into m*ntenance of live disconnection, m*ntenance of socket electric shock, outdoor electric shock and other principle demonstrations. The teaching of low-voltage electric shock and high-voltage electric shock m*nly expl*ns and demonstrates to students how to rescue people who are in low-voltage electric shock or high-voltage electric shock. Artificial respiration rescue method, hand-holding breathing rescue method, and chest compression rescue method are displayed using 3D virtual simulation technology. After rendering and polishing, the model looks the same as the real parts and the picture is realistic. Through practical tr*ning, students can be educated on safe use of electricity in the tr*ning room, improve their safety awareness, learn some self-rescue methods, and take cert*n safety measures to protect themselves when they encounter danger, and be familiar with the causes of various electrical accidents and practical operational measures to deal with electrical accidents, so as to reduce the occurrence of electrical accidents. In order to prevent false bidding, this system is demonstrated at the bidding site.
Mechanical equipment installation tr*ning assessment software: The software is based on C# and JS language programming design. Users can choose different interactive interface sizes according to the computer configuration. Six levels of image quality can be selected, including smooth image quality, medium image quality, and perfect image quality. More than ten kinds of shaft systems such as gear shaft system and worm shaft system can be selected for installation, disassembly, assembly, parts measurement, assessment, etc. There are intelligent reminders during the steps of disassembling and assembling parts. The models in the software are all 3D models, made by 3Dmax, and rendered and polished to make the models look the same as real parts. There are non-standard parts library, standard parts library, and measuring tool library for disassembly and assembly. The software is equipped with integrated electronic experiment test questions and instructions for the purpose, steps, requirements, etc. of the experiment. When using the assessment function, the software randomly asks questions for students to answer, and gives the assessment score when the students finish answering the questions. This software can be rotated, enlarged, and reduced to view its det*ls in all directions. Provide live demonstration.
Single-chip microcomputer , plc programmable design and control virtual simulation software (copyright certificate and demonstration video required):
1) This software is developed based on unity3d, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the start/stop, forward motion, and reverse motion buttons can be used to operate the 3D machine tool model movement. When the line is connected, the 3D machine tool model can be enlarged/reduced and translated.
2) Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiter is placed on the three-dimensional machine tool model. You can choose to cover the cover. Some component names can be renamed. Then click the connect line button to connect the terminals. After the machine tool circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up. The scene can be reset at any time.
3) PLC control: The experiment is the same as relay control, and the PLC control function is added. After the connection is completed, enter the program writing interface through the PLC coding button. Write two forward and reverse programs. There are 12 ladder diagram symbols in total. After writing, select Submit for program verification. After successful verification, turn on the power to operate. If there are component, line connection, and code errors, an error box will pop up. The scene can be reset at any time.
4) Single-chip microcomputer control: The experiment is the same as relay control, with the addition of single-chip microcomputer control function. After the connection is completed, enter the programming interface through the C coding button, enter the correct C language code, submit and verify successfully, turn on the power to operate, and an error box will pop up for components, line connections, and code errors, and the scene can be reset at any time.
