Central Control System
With the continuous development of society, information exchange and communication have become more and more frequent and more and more important. Various audio-visual equipment, projection equipment, conference systems, etc. have begun to enter various industries. Today's conference rooms, electrified teaching rooms, etc., are no longer a stand, a chair, a microphone, and replaced by advanced multimedia conferences and teaching equipment. Such as: projectors, DVD players, video recorders, video display consoles, multimedia computers, electric screens, some large conference rooms are also equipped with simultaneous interpretation system, electronic voting system, large screen projection, multi-screen switching system. The use of multiple devices must lead to cumbersome device operations. For example, to turn on the power of various devices, turn off the lights, frequently switch various audio and video signals, and constantly switch the projection screen.....etc. In this case, a "central control system" device capable of centrally managing these devices and simultaneously controlling various resources in the conference room and classrooms came into being.
