Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one: referring to Fig.1-2, a kind of instructional terminal screen switching control system, including record-broadcast all-in-one machine, center control
The fixed video camera of host processed, vibrating sensor, teacher side computer, blackboard, autotracking video camera, student terminal, digital sound
Frequency processor, sound reinforcement system, teacher/blackboard switching push button and teacher/throwing screen switching push button, the fixed video camera of blackboard and automatically with
Track video camera is electrically connected with record-broadcast all-in-one machine respectively, sound reinforcement system and digital audio processor wired connection, at digital audio
Device and record-broadcast all-in-one machine wired connection are managed, record-broadcast all-in-one machine and central control host are electrically connected, teacher side computer and center
It controls host to be electrically connected, vibrating sensor, teacher/blackboard switching push button and teacher/throwing screen switching push button are controlled with center respectively
Host processed is electrically connected, and record-broadcast all-in-one machine and student terminal are electrically connected.
Wherein, autotracking video camera is the high-speed ball-forming machine of model JVS-C-P50N2S-Z25, and teacher side computer will
The content real-time transmission shown in its display to central control host, teacher/blackboard switching push button and teacher/throwing screen switching is pressed
Button is button sensor.
In the present embodiment, vibrating sensor is distributed in the quadrangle of blackboard, and it is stronger to be installed on concealment on blackboard, more beautiful
It sees.
When carrying out classroom instruction, the fixed video camera fixation of blackboard shoots blackboard, and autotracking video camera is to teacher
Track up is carried out, the picture that the fixed video camera of blackboard, autotracking video camera are shot is sent to record-broadcast all-in-one machine, expands
Sound system expands the sound of microphone, and is sent to digital audio processor, after digital audio processor carries out transcoding, passes
It send to record-broadcast all-in-one machine, the content liquid shown on teacher side computer is sent to record-broadcast all-in-one machine, and then record-broadcast all-in-one machine will not
It is handled with the video information in source and audio-frequency information sub-channel packing, is uniformly sent to central control host, central control host
After the processing of information sub-channel, the video information of teachers ' teaching is sent back into record-broadcast all-in-one machine, student can watch in student terminal；
Central control host defaults student terminal and shows autotracking video camera shooting picture, that is, shows the movement of teacher, work as religion
For teacher when writing on blackboard, vibrating sensor senses the vibration of blackboard, transmits signals to central control host, center control
Mian engine changeover channel continues 10s or more when teacher stops writing, vibrating sensor is no longer right to the picture of the fixed video camera of blackboard
Central control host transmits signal, switches back into autotracking video camera shooting picture；
When teacher requires student viewing to throw screen, teacher/throwing screen switching push button is pressed, teacher/throwing screen switching push button transmits signal
To central control host, teacher side Computer display picture is switched to, then shoots picture by autotracking video camera is once switched back into
Face；Teacher is without writing, it is desirable that when student looks at the blackboard, presses teacher/blackboard switching push button, switches to the fixed video camera of blackboard
Shooting picture, then autotracking video camera shooting picture is switched back by primary.
