Abstract
The invention discloses an internal video distributor of medical case. The case comprises 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 the same circuit board. A RGB signal input by the one-way video input interface is processed by the RGB signal amplifying distributor, a traveling-field signal is processed by the traveling-field signal amplifying distributor, and the processed RGB signal and traveling-field signal are output by the three-way video output interface. According to the video distributor, the distribution rationality of the video distributor with the internal medical case is improved effectively, and the performance of the video distributor is also improved.
Description
Technical field
The present invention relates to the video distributor field, be 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 through the video distributor internal circuit, is widely used in the medical electrical equipment.Video distributor layout in the prior art electro-medical mechanism of qi case 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 complicacy of video distributor.
Summary of the invention
The object of the invention provides the built-in video distributor of a kind of medical cabinet, to solve the medical cabinet wiring complicated problems that prior art is equipped with video distributor.
In order to achieve the above object, the technical scheme that the present invention adopted is:
The built-in video distributor of a kind of medical cabinet; It is characterized in that: include the rgb signal that is integrated on the same wiring board and amplify distributor, row field signal amplification distributor; 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 said 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 on the said wiring board respectively with wiring board on rgb signal amplify distributor, row field signal amplifies the four-core socket that the distributor power end is connected, said Switching Power Supply is supplied power through the four-core socket, and rgb signal amplifies distributor, row field signal amplification distributor to the wiring board.
The built-in video distributor of described a kind of medical cabinet; It is characterized in that: on the said wiring board rgb signal amplify distributor comprise by the triode common base connect amplifying circuit that method constitutes, by the two-stage emitter-base bandgap grading tracker that triode constitutes, 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: row field signal amplification distributor comprises that the two-stage model is respectively the reverse trigger of six tunnel Schmidts of 74LS14 on the said 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 present invention 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 make things convenient for the installation of video distributor in medical cabinet greatly, need not connect many holding wires in addition, make medical chassis arrangement succinct; The amplifying circuit that adopts the triode common base to connect method simultaneously to constitute, the two-stage emitter-base bandgap grading tracker that is made up of triode are handled the rgb signal in the vision signal; Adopt the reverse trigger of two-stage six tunnel Schmidts to handle the row field signal in the vision signal, make the synchronous degree of vision signal of last three tunnel outputs higher, reduced the influence of disturbing.The present invention can effectively improve the rationally distributed property of the video distributor that medical cabinet is installed, and has also improved the performance of video distributor.
