The invention relates to the field of multimedia teaching technology, in particular to a multimedia information system based on optical communication. The system comprises a server, a lighting lamp, ateacher terminal and a student terminal. The lighting lamp is provided with a signal transmitting module for transmitting data of the server by an optical signal of the lighting lamp. Each of the teacher terminal and the student terminal is provided with an optical signal receiving module for receiving the optical signal from the lighting lamp and a wireless communication module; and the teacherterminal and the student terminal are in data connection with the server by the wireless communication modules. Each of the teacher terminal and the student terminal includes a display module and an operation input module; the operation input module is used for inputting an experiment operation by a student or a teacher; and the wireless communication modules are used for sending the experiment operation from the student or teacher to the server. With the multimedia information system, the student is able to carry out a simulated experiment manually, so that the teaching quality of the experiment teaching is improved.
Description
technical field [0001] The invention relates to the technical field of multimedia teaching, in particular to a multimedia information system based on optical communication. Background technique [0002] At present, with the rapid development of multimedia and information technology, classroom teaching methods are also flexible and diverse. With the continuous progress of the modern process of educational technology, multimedia teaching is indispensable as an advanced teaching method. All kinds of schools and academic units are building multimedia classrooms or multi-functional halls. Multimedia teaching integrates sound, image, video, text and other media, which can be used as an effective auxiliary teaching method, and can intuitively display the content to be presented, which is convenient for understanding, and can not only impart knowledge, develop The purpose of cultivating intelligence and ability can also realize the purpose of teaching students in accordance with t...
