Description
Affiliated technical field
The utility model relates to a kind of removable digital projection teaching equipment, each place that especially can move to the classroom easily is projection student's operation and student's activities in real time, can also take the prepare lessons aid of office as teacher, can allow teacher that student's the timely Taking Pictures recording of operation situation is prepared against and comment on class, thereby improve classroom efficiency greatly.
Background technology
At present, the projector equipment of known school all is the projector for real object that is fixed on the dais, what all will go to taking on the dais projection, and sometimes can't projection such as student's experiment scene, field experiment also can only one group of student of projection to the dais even the student is last, and the camera lens projecting direction is regulated dumb.Also have when projection student's written assignment, can only accept projection one by one to student's operation, when projection, do not have own operation in student's hand, correct inefficiency.If the use computer screen also will switch to computer screen by projector for real object, use inconvenience in addition.
Summary of the invention
In order to overcome the deficiency of projection in kind fixing on the existing dais, the utility model provides removable digital projection equipment, this equipment not only moves to each place operation of projection student in real time in classroom easily, and take the prepare lessons aid of office as teacher, can allow teacher that student's the timely Taking Pictures recording of operation situation is prepared against and comment on class, needn't switch projection simultaneously because the computer screen that itself just is to use.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of removable digital projection teaching equipment, varifocal camera links to each other with video frequency collection card by video line, link to each other with 12V dc output power adapter by power lead, and camera is fixed on the gimballed base, video frequency collection card is put into computer, gather video to computer screen by video frequency collection card, project on the giant-screen by projector then, camera adopts manual varifocal camera, can the manual adjustments sharpness, the camera rear portion button of taking pictures in addition can be taken pictures in real time in addition, the camera rear portion has also added the storage of Secure Digital Card card, can directly deposit photo that photographed or video on the Secure Digital Card card button and the Secure Digital Card card storage of also can not taking pictures of camera rear portion.
Concrete operational version is: video acquisition is snapped fits into computer, install and drive and software, video frequency collection card connects camera by video line, the camera line of also will connecting with the mains, connect 12V dc output power adapter by power lead, 12V dc output power adapter connects the 220V alternating current, and camera is fixed on the gimballed base.Computer is opened image projection that projector that software just can be by the classroom takes camera on giant-screen.Teacher can hold any old place of the camera of band base to the classroom, camera is put on student's desk the just student's of projection in real time operation or student's activities, and the camera direction can be regulated enhancing teachers and students interaction, saving time in classroom arbitrarily.In teacher's Office PC, also equip a video frequency collection card in addition, teacher can take off camera after class and take back office and receive on the Office PC, link to each other with computer by camera, teacher can take pictures and is recorded in the computer in the process of correcting students' papers student's operation, take pictures and to take pictures by computer software, also can take pictures with the camera back button of taking pictures, in the Secure Digital Card card after photo can be deposited computer or directly deposit camera, go up class hour like this, the photo of clapping is examined on the computer in classroom, the operation photo that can show take by the computer giant-screen, and operation just can be issued the student, just can contrast giant-screen when commenting on and comment on, the operation of oneself is also arranged in student's hand, comment on efficient thereby improved greatly.
The beneficial effects of the utility model are, camera can move to each place operation of projection student in real time in classroom easily, can also take the prepare lessons aid of office as teacher, can allow teacher that student's the timely Taking Pictures recording of operation situation is prepared against comments on class, thereby improve classroom efficiency greatly, this scheme is revolutionary change for traditional projection fixing in kind, also is to give lessons the once reform of mode of traditional blackboard.
