Multimedia Intelligent Control "Mechanical Principles and Mechanical Design" Showcase
This "Principle of Machinery and Mechanical Design" showcase is a set of electrified multimedia teaching equipment designed according to the national tenth-five-year plan textbooks compiled by the Teaching and Research Office of Mechanical Principles and Mechanical Design of Tianjin University. most. The display cabinet is divided into ten cabinets and a computer console for multimedia voice-controlled simultaneous interpretation demonstration. The PC controls the sequence or optionally runs each cabinet model action, and the computer plays the graphics to synchronize the model actions. And the contents of each cabinet are written in a PPT format on the computer. The content includes tutorial data such as mechanical principles, mechanical design, and course design. The PowerPoint presentations are used for slide shows to facilitate students' study and research outside the classroom. The whole upper and lower cabinets of this display cabinet are made of colorful plastic steel structure, which is durable and beautiful in appearance.
Main features: ( teaching equipment | teaching instrument )
Console configuration: one set of control simulation software; one P4 computer host and one 17-inch monitor.
Control software: The display cabinet dedicated playback software is used to realize the synchronized actions of sound, images and models, and various playback schemes (such as forward, backward, stop, step, cycle, etc.) are also available; optional and sequential actions can also be realized.
Control method: use mouse and remote control.
