The invention discloses a multimedia remote teaching device, comprising a control platform center, a teaching video acquisition terminal, a recording and broadcasting terminal connected with the control platform center, and a storage and sharing cloud, wherein the storage and sharing cloud is connected with a plurality of playing terminals through remote communication. The teaching video collection end includes a support table and an intelligent electronic device installed on the support table and integrating a video collector, an audio collector and a control memory, and the support table includes a support leg and a support panel mounted on the support leg. , an installation cavity is processed in the support panel, and a power mechanism for pushing out and accommodating intelligent electronic equipment is installed in the installation cavity. The teaching video collection terminal of the present invention can be directly stored when not in use, thereby avoiding malicious damage to the intelligent electronic equipment by persons other than the teaching teacher, and improving the security of the entire remote teaching device.
Description
technical field [0001] The invention relates to the field of multimedia teaching, in particular to a multimedia distance teaching device. Background technique [0002] In recent years, with the rapid development of computer communication technology and projection technology, multimedia distance education has gradually replaced the traditional blackboard teaching method. The existing multimedia distance teaching system is roughly composed of educational video collection terminal, control center, student terminal and remote mobile client terminal. Connect remote mobile client terminals through wireless communication to realize synchronous teaching. Among them, the educational video collection terminal is mainly composed of electronic equipment that can collect video screen information and audio information, signal converters and control single-chip microcomputers, and converts the teaching screen and voice of the teacher in real time and transmits them to the control center f...
