Abstract
The present invention relates to a kind of virtual instruction video system, mainly solves the problem of video system functions existing in the prior art are more single, not can be carried out real-time switching at runtime, bring certain limitation to the visual field that user watches, are not able to satisfy teaching demand.The instructional video system, indoor teacher's camera and student's camera are taught including being mounted on teaching, the video matrix that input terminal is connected with teacher's camera and student's camera, the video distributor that input terminal is connected with video matrix, the central controller that input terminal is connected with video distributor.Through the above scheme, invention achieves multiple functional, energy real-time perfoming screen switchings, and the visual field is more wide, can sufficiently meet the purpose of teaching demand, has very high practical value and promotional value.
Description
Technical field
The present invention relates to tutoring system technical field more particularly to a kind of virtual instruction video systems.
Background technique
With advances in technology, intelligent tutoring auxiliary system is applied in modern teaching more and more widely, so that former
The teaching of this dullness is rich in diversity, interest, and intelligent tutoring auxiliary system is mainly by audio system, video system and control system
System is constituted, wherein video system is highly important part in the system, and the quality of performance directly influences the use of teachers and students
Experience only has single video record function however, existing video system carries out picture broadcasting mostly in fixed area
Can, it not can be carried out real-time switching at runtime, certain limitation is brought in the visual field watched to user, is increasingly unable to satisfy
Teaching demand.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of virtual instruction video system.
The present invention is achieved through the following technical solutions:
A kind of virtual instruction video system, including be mounted on teaching and teach indoor teacher's camera and student's camera,
The video matrix that input terminal is connected with teacher's camera and student's camera, the video distribution that input terminal is connected with video matrix
Device, the central controller that input terminal is connected with video distributor.
Further, the video matrix is connected with operation module by RS485 interface, and the RS485 interface is set to
On video matrix.
Compared with prior art, the beneficial effects of the present invention are: the present invention passes through video matrix, video distributor, picture
The setting of face divider makes it possible to carry out the picture of monitoring high definition, the observation of more pictures, and is provided with DVD player and TV box,
Enrich source video sequence.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Please refer to a kind of virtual instruction video system shown in FIG. 1, including teacher's camera: it is right in teaching classroom to be installed on
The picture of teacher is recorded, and by the delivery of video of recording to video matrix；
Student's camera: it is installed in teaching classroom and the picture of student is recorded, and extremely by the delivery of video of recording
Video matrix；
Video matrix: appointed by the multi-channel video signal that teacher's camera and student's camera are transmitted to by array switching
In meaning output to video distributor；
Video distributor: being equally assigned into multi-channel video signal for the vision signal original received, and by the multichannel of distribution
Vision signal is transferred to central controller respectively and is handled, and is transferred to image splitter and is shown；
Central controller: the vision signal received is handled, and vision signal passes through projector by treated
It is shown, is transmitted by harvester；
DVD player: the transmitting of high definition picture is carried out；
TV box: video acquisition and compression are carried out；
Projector: video signal projection is carried out according to the instruction of central controller；
Harvester: to central controller, treated that vision signal is acquired；
Image splitter: the video pictures received are split, so that can show on same video player
The monitored picture of multiple video cameras.
Wherein, the output end of teacher's camera and student's camera is connected with video matrix, the output end of video matrix
It is connected with video distributor, the input terminal of image splitter and central controller is connected with video distributor, TV box and DVD
The output end of machine is connected with central controller, and the input terminal of projector and harvester is connected with central controller, in order to just
In operation, video matrix is also connected with operation module, and digit preference keyboard is as operation module in the present invention, it is contemplated that application
Flexibility, RS485 interface is provided on video matrix, and numeric keypad is connected by the RS485 interface with video matrix.
In order to realize invention, teacher's camera, student's camera, projector, DVD player need to be only installed in teaching classroom
It is interior, central controller, TV box, numeric keypad, video matrix, video distributor, image splitter, harvester can be respectively provided with
In a special Central Control Room, this system is opened, can realize the detection to student, the multiple pictures of teacher, operates numeric keypad
It can realize the switching to picture.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
