单价:84000元/套 Multimedia intelligent control "Mechanical Engineering Drawing" complete laboratory equipment unit price: 84000 yuan / set
This "Mechanical Engineering Drawing" showcase is a compulsory professional technical course for students majoring in mechanical engineering in higher vocational colleges. It is a showcase that trains students to correctly read and draw mechanical drawings, enhances students' basic engineering skills, and has strong practicality device. Focusing on cultivating students' ability to read and draw engineering drawings as the core, on the basis of a moderate degree of theoretical knowledge, highlight the practical teaching link. At the same time, with the help of computer graphics technology and multimedia technology, intuitive teaching is strengthened to achieve an intuitive image of teaching content, increase learning interest and reduce learning difficulty. The display cabinet is divided into ten cabinets and a computer console. The multimedia engineering demonstration software is used for multimedia demonstration. The PC computer controls the sequence or optionally plays the animation image to demonstrate the model function. ( Teaching Equipment | Teaching Instruments )
Console configuration: mechanical engineering drawing simulation software (including 121 animations), one set of hardware; one P4 computer host and one 17-inch display.
Control software: Use the dedicated playback software of the Kerong display cabinet to achieve image demonstration actions, and use a variety of playback schemes (such as forward, backward, stop, step, cycle, etc.); optional and sequential actions can also be achieved.
Control method: use mouse and computer remote control.
Display cabinet size: 1250 × 430 × 1780mm,
The upper and lower display cabinets are made of colored plastic steel as a whole, which is beautiful in appearance and durable.
