Description
Technical field
The utility model relates to a kind of automatic switch controller, and specifically one is applied to classroom multimedia automatic switch controller, belongs to electronic products manufacturing technology field.
Background technology
At present in Ge great universities and colleges, classroom is all provided with multimedia, but the multimedia in classroom is all by manually operating, and before goes to classroom to open multimedia at school.Different teaching buildings is had in school, different floors all can have multi-media classroom, such operation will arrange more people, not only time-consuming but also take a lot of work, sometimes operationally may there is the phenomenon of omitting, occur out multimedia sometimes, the phenomenon that teacher has tune class or suspends classes, namely waste electricity, reduce again the serviceable life of multimedia camera lens; On the other hand, the multimedia in existing classroom can not flexible be allocated, and often causes wasting of resources phenomenon.
Utility model content
The purpose of this utility model many people will be arranged to operate control separately in order to solve existing multi-media classroom, not only time-consuming but also take a lot of work, sometimes the phenomenon of omitting may operationally be there is, there is out multimedia sometimes, the phenomenon that teacher has tune class or suspends classes, namely wastes electricity, reduces again the serviceable life of multimedia camera lens, also often cause wasting of resources phenomenon, thus a kind of new technical scheme is provided.
For achieving the above object, the utility model realizes by following scheme:
One is applied to classroom multimedia automatic switch controller, it includes display screen, PC, single-chip microcomputer, infrared tube, relay and multimedia switch, and be electrically connected by circuit, multi-media classroom doorway is provided with infrared tube and is connected with single-chip microcomputer, single-chip microcomputer is electrically connected by relay and multimedia switch; Single-chip microcomputer is electrically connected by the display screen in PC and Control Room.
Be provided with pipe A and pipe B two infrared tubes in infrared tube, pipe A and pipe B interval 0.4m installs and arranges.
The beneficial effects of the utility model are: circuit structure is simple, automaticity is high, can long-rangely monitor, classroom can be detected whether attend class, multimedia for each classroom state can be carried out renewal display in real time by LED display simultaneously, decrease multi-media classroom attendant to be equipped with, thus effectively economize on resources and provide convenience for class-teaching of teacher.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment schematic block circuit diagram of the utility model.
Fig. 2 is infrared tube 4 schematic block circuit diagram in the utility model accompanying drawing 1.
In figure, 1. display screen, 2.PC machine, 3. single-chip microcomputer, 4. infrared tube, 5. relay, 6. multimedia switch, 7. pipe A, 8. pipe B.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
One is applied to classroom multimedia automatic switch controller, it is, at Control Room, a display screen 1 is housed, in each classroom, a pair infrared tube 4 is installed at front/rear door place, pipe A7 and pipe B8 two infrared tubes are provided with in infrared tube 4, the two is greater than 0.4m and installs along the interval, direction of entering, and sheathing material is saved in 0.4m installation in interval most, relay 5 series winding is entered the classroom in multimedia control circuit simultaneously, infrared tube 4 is connected with single-chip microcomputer 3, single-chip microcomputer 3 is connected with PC 2 with relay 5 respectively, and PC 2 is connected with display screen 1.Relay 5 is connected with multimedia switch 6.AT89C51 type selected by single-chip microcomputer 3, and display screen 1 selects LED screen.
Principle of work of the present utility model is, based on the ACTIVE CONTROL of single-chip microcomputer 3, the pipe A7 in employing infrared tube 4, the trigger sequence of pipe B8 judge that classroom has people enter or go out, if first trigger pipe A7, trigger after pipe B8, be judged as that someone enters classroom, if first trigger pipe B8, contrary; In 10 minutes before the class and in 20 minutes after class, communicate when single-chip microcomputer 3 detection statistics has number to change to PC 2, PC 2 statistics, upgrades the display state of display screen 1 simultaneously; PC 2 is according to everyone logarithmic data counted on, and whether determine to have to need switch classroom multimedia, if desired then communicate to single-chip microcomputer 3, the electric power of the multimedia switch 6 in this classroom opened by single-chip microcomputer 3 pilot relay 5.If desired manual operation, then will need manually-operated multi-media classroom to get rid of outside the automatic range of control of entirety by PC 2.
The utility model utilizes infrared tube 4 to detect multi-media classroom number, by the communicate mutual transmission of information of single-chip microcomputer 3 with PC 2, thus the multimedia electric power break-make of multi-media classroom is controlled by pilot relay 5, show the state of teaching building multi-media classroom in real time simultaneously, and then reach reasonable distribution teaching resource and the teaching facilitating classroom, reduce the outfit of class management personnel, effectively save manpower and electric power resource, for class-teaching of teacher is provided convenience.
