Abstract
The utility model discloses a built-in video distributor of a medical case, comprising a red green blue (RGB) signal amplifying distributor, a traveling-field signal amplifying distributor, a one-way video input interface, a three-way video output interface which are integrated on a same circuit board. A RGB signal input by the one-way video input interface is processed by the RGB signal amplifying distributor on the circuit board. A traveling-field signal is processed by the traveling-field signal amplifying distributor. Then the processed RGB signal and the processed traveling-field signal are respectively output by the three-way video output interface. According to the utility model, the layout rationality of the medical case provided with the video distributor is improved effectively, and the performance of the video distributor is also improved.
Description
Technical field
The utility model relates to the video distributor field, is specially the built-in video distributor of a kind of medical cabinet.
Background technology
Video distributor is a kind of the video signal source average mark to be made into the equipment of multi-channel video signal, its objective is the multichannel output that realizes single channel video source input signal by the video distributor internal circuit, is widely used in the medical electrical equipment.Video distributor layout in the medical electric cabinet of prior art is at random, and vision signal input, delivery outlet and video distributor circuit do not integrate, and causes being equipped with the medical cabinet wiring complexity of video distributor.
The utility model content
The utility model purpose provides the built-in video distributor of a kind of medical cabinet, and the problem of the medical cabinet wiring complexity of video distributor is installed to solve prior art.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
The built-in video distributor of a kind of medical cabinet, it is characterized in that: include the rgb signal amplification distributor, the row field signal amplification distributor that are integrated on the same wiring board, and single channel video input interface, three road video output interfaces, the input of rgb signal amplification distributor, row field signal amplification distributor is connected with the single channel video input interface respectively on the described wiring board, and the output of rgb signal amplification distributor, row field signal amplification distributor is connected with three road video output interfaces respectively on the wiring board.
The built-in video distributor of described a kind of medical cabinet, it is characterized in that: also include Switching Power Supply, also be provided with respectively the four-core socket that is connected with rgb signal amplification distributor, row field signal amplification distributor power end on the wiring board on the described wiring board, described Switching Power Supply supplies power to rgb signal amplification distributor on the wiring board, row field signal amplification distributor by the four-core socket.
The built-in video distributor of described a kind of medical cabinet, it is characterized in that: on the described wiring board rgb signal amplification distributor comprise the amplifying circuit that consisted of by triode common base connection, by the two-stage emitter-base bandgap grading tracker that triode consists of, the rgb signal of video input interface input is successively through exporting from three road video output interfaces respectively behind amplifying circuit, the two-stage emitter-base bandgap grading tracker on the wiring board.
The built-in video distributor of described a kind of medical cabinet, it is characterized in that: the row field signal amplification distributor comprises that the two-stage model is respectively the reverse trigger of six tunnel Schmidts of 74LS14 on the described wiring board, exports from three road video output interfaces respectively after the reverse trigger reverse process of row field signal process two-stage Schmidt of video input interface input on the wiring board.
The utility model is in the circuit board integrated respectively with single channel video signal input interface and three road video signal output interfaces, thereby become one with the video distributor internal circuit, can greatly make things convenient for the installation of video distributor in medical cabinet, need not connect in addition many holding wires, make medical chassis arrangement succinct, the amplifying circuit that adopts simultaneously triode common base connection to consist of, the two-stage emitter-base bandgap grading tracker that is made of triode is processed the rgb signal in the vision signal, adopt the row field signal in the reverse trigger processing of two-stage six tunnel Schmidts vision signal, make the synchronous degree of vision signal of last three tunnel outputs higher, reduced the impact of disturbing.The utility model energy Effective Raise is equipped with the rationally distributed property of the video distributor of medical cabinet, has also improved the performance of video distributor.
