System generation

With the continuous development of society, information exchange and communication have become more frequent and more important. Various audio-visual equipment, projection equipment, conference systems, etc. began to enter all walks of life. The current meeting rooms, audio-visual teaching rooms, etc., are no longer the previous one, one podium, one chair and one microphone. Instead, they are replaced by a variety of advanced multimedia conference and teaching equipment. Such as: projectors, video disc players, video recorders, video display stands, multimedia computers, electric screens, some large conference rooms are also equipped with simultaneous interpretation systems, electronic voting systems, large screen projections, multi-screen switching systems, etc. The use of multiple devices will inevitably bring complicated device operations. Such as: to turn on the power of a variety of equipment, to turn off the lights, to frequently switch various audio and video signals, to constantly switch the projection screen... etc. In this case, a "central control system" device that can centrally manage these devices and simultaneously control various resources in conference rooms and classrooms has emerged.
