Abstract
The utility model discloses a screen switching device of a computer for multimedia teaching, which is characterized in that a screen switching device is arranged between the output port of a display card and the input port of a display of a mainframe used by students, and the screen switching device is provided with two input ports and one output port. A multiway switching switch is connected between the two input ports and the output port. One input port is connected with the output port of the display card of the mainframe for students, the other input port is connected with the output port of a display card of a mainframe for teachers, and the output port is connected with the input port of the display for students. Therefore, the utility model can realize the quick and convenient conversion of the image on the display of the mainframe for students between the output of the mainframe for teachers and the output of the mainframe for students, and use the display of the mainframe for students without the need of investing additional display devices.
Description
One, technical field:
The utility model relates to computer realm, specifically a kind of the computer teaching middle school student with the machine display can be between teacher's host signal and student's local host signal device for switching.
Two, background technology:
At present, infotech has obtained swift and violent development, popular along with the Windows Windows, past is that the form of teaching of educational aid has been difficult to satisfy the current microcomputer teaching that makes rapid progress with chalk, blackboard, in order to solve this difficult problem, the brainstrust invention has been made multi-media classroom and has been used many audio-visual productss such as large screen projector, multifunction teaching card, and the teaching efficiency of these products is good.But the most fatal weakness be cost an arm and a leg, use loaded down with trivial details.Be difficult in vast rural area, apply remote districts.Market in urgent need provides the computer screen switch that is used for microcomputer teaching of a kind of practicality, cheapness, flexible and convenient operation.
Three, summary of the invention:
The purpose of this utility model is for the student provides a kind of computer screen switch with machine, and it is mainly used in and guarantees that the student uses the quick switching of machine indicator screen between the student exports with main frame with machine output and teacher.
For solving above-mentioned task, the solution that the utility model adopted is: between the display card output port of the used main frame of student and the used display input port of student a screen switcher is housed, screen switcher is equipped with two input ports and an output port, between two input ports and an output port, connect a multi-channel switch, an input port of screen switcher connects the display card output port of the used main frame of student, another screen switcher input port connects the display card output port of teacher's main frame, and the output port of screen switcher connects the used display input port of student.
Owing to adopted above-mentioned technical solution and structural design, computer screen switch of the present utility model can realize that the student can change fast, easily with the image on the machine display between output of teacher's main frame and the output of student's main frame, because of using the display of student, so need not invest other display device with machine.It is scientific and reasonable to the utlity model has technical scheme, the control device economic and reliable, easy to maintenance, practical, expense is cheap, satisfactory for result.In the multimedia teaching practice of vast rural area, remote districts, vast market is arranged.
Four, description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing is a principle schematic of the present utility model;
Indicate in the accompanying drawing: the display card output port 1 of teacher's main frame, the display card output port 2 of the used main frame of student, screen switcher input port 3, multi-channel switch 4, screen switcher output port 5, the used display input port 6 of student.
Five, embodiment:
In conjunction with the accompanying drawings, between the display card output port 2 of the used main frame of student and the used display input port 6 of student, a screen switcher is housed, screen switcher is equipped with two screen switcher input ports 3 and a screen switcher output port 5, between two screen switcher input ports 3 and a screen switcher output port 5, connect a multi-channel switch 4, an input port 3 of screen switcher connects the display card output port 2 of the used main frame of student, another screen switcher input port 3 connects the display card output port 1 of teacher's main frame, and the output port 5 of screen switcher connects the used display input port 6 of student.
Certainly, present embodiment has only been expressed a kind of mentality of designing of the present utility model, and all only conversion are of the present utility model to patch form and reach the various conversion of the present utility model purpose, all should drop within the protection domain of the present utility model.
