Photoelectric isolation type video input switcher special for endoscope workstation

Abstract

The invention discloses a photoelectric isolation type video input switcher special for an endoscope workstation. The switcher comprises a machine shell, an optical splitter and a mounting plate body;an optical transmitter I is arranged in the machine shell; an optical transmitter II is mounted below the optical transmitter I; an isolation plate is installed on the left side of the first opticaltransmitter. The optical splitter is installed in the isolation plate, an optical end receiver is arranged on the left side of the optical splitter, a front cover is arranged on the front end face ofthe machine shell, a display screen is arranged in the front cover, the installation plate body is installed on the right side of the display screen, and a filter screen is installed on the right sideof the installation plate body. According to the video input switcher, the first video optical transmitter and the second video optical transmitter are applied, and when optical isolation is adoptedand a video signal source is switched, hot plug of video signals cannot be generated as long as optical signals are switched rather than electric signals are switched, so the crash phenomenon of an image workstation cannot be caused.

Description

technical field [0001] The invention relates to the technical field of video switchers, in particular to a photoelectric isolation type video input switcher dedicated to endoscopy workstations. Background technique [0002] The video switcher is designed for the switching of special composite video signals. It can switch any video signal output to the display device. The function of the video switcher is to switch, repeat, process and copy the image signal transmitted by the system. The commonly used circuit- The optical path-circuit video switcher has a high price and is suitable for long-distance high-quality transmission. In endoscopy work, a low-cost video switcher for short distance can be studied. [0003] At present, in actual clinical use, the function of the endoscope image workstation is to intercept the video from the endoscope host, and sometimes the video source needs to be switched frequently. Therefore, we propose a dedicated video input switcher for photoele...

Problems solved by technology

[0004] The purpose of the present invention is to provide a dedicated video input switcher for a photoelectrically isolated endoscope workstation, which solves the traditional problem that in actual clinical use, the function of the endoscope image workstation is to intercept the video from the endoscope host, which sometimes requires frequent When switching video sources, the workstation does not support video signal hot-swapping, which often leads to failures such as the crash of the workstation host
