The function interface block diagram that shows screen display when Fig. 2 is the built-in centralized control system running software of the PC among Fig. 1 at PC.
Reference numeral in the above-mentioned accompanying drawing is as follows:
PC 1, control performance element 2, the button 3 of giving a lesson, the button 4 of finishing class, equipment general supply 5, projector 6, projection screen 7.
Embodiment
(embodiment 1)
See Fig. 1, the Multimedia Classrooms central control device of present embodiment by PC 1, control performance element 2, on class button 3, button 4 and equipment general supply 5 form after class.Equipment general supply 5 provides power supply for the teaching equipment that comprises projector 6, projection screen 7, power amplifier, microphone etc. in the classroom.But the power supply of PC 1 and control performance element 2 is provided by civil power.
PC 1 is general personal computer, and be built-in with centralized control system software in this PC 1, this software is when PC 1 interior operation, its function interface that shows screen display at PC as shown in Figure 2, comprise video signal functions bar, rgb signal function bar, projector closing function bar, projector open function bar, projection screen rising function bar and projection screen decline function bar etc., teacher clicks relevant function bar, and PC 1 namely sends the instruction of carrying out corresponding function to control performance element 2.
Control performance element 2 is provided with single-chip microcomputer, 2 RS232 communication interfaces and device power supply (DPS) switch control end, projection screen Electric Machine Control output terminal.Single-chip microcomputer has the end of patrolling and examining.The button 3 of giving a lesson is the contact button with the button 4 of finishing class, and button 3 and the button 4 of finishing class all are arranged on the dais in classroom on class.
Control performance element 2 is electrically connected with the PORT COM of PC 1 by its RS232 communication interface; Button 3 also is the power switch of PC 1 on class; Button 4 is electrically connected with the end of patrolling and examining of the single-chip microcomputer of control performance element 2 after class;
The Multimedia Classrooms central control device of present embodiment in use, the switch of device power supply (DPS) switch control end and the equipment general supply 5 of control performance element 2 opens and closes end and is electrically connected, and controls the opening and closing of performance element 2 opertaing device general supplies 5; Control performance element 2 is electrically connected by the communication port of the projector 6 in its 2nd RS232 communication port and the classroom, the projection screen Electric Machine Control output terminal of control performance element 2 is electrically connected with the controlled end of the control electric system of projection screen 7, and control performance element 2 passes through the open and close of opertaing device general supply 5 and then controls the opening and closing of the teaching equipments such as power amplifier, microphone.
The Multimedia Classrooms central control device course of work of present embodiment such as following:
