Description
Technical field
The present invention relates to the high-resolution video network control system that a kind of computer utility network system, particularly LAN (Local Area Network) combine with the high-resolution video transmission.
Background technology
In the guard monitor field, great majority are that the analog video signal of will simulate camera is transferred to the multi-channel video switch at present, after switching, be transferred to the image collecting device of monitor or computing machine again, because the processing power of single computer or several computing machines is limited, can not handle in real time each road vision signal, maybe very low intelligence can only not arranged so this system majority does not have intelligence.The intelligent safety system need carry out independent real-time processing to each road vision signal usually, so rational structure is all to use a special computing machine to handle to each road vision signal; For the place that requires to lay special stress on protecting many intellectual monitoring subsystems that have imageing sensor need be installed within the specific limits usually; the operator operates or observes in a pulpit on-the-spot away from monitoring, and this operates control or observation by network to each subsystem with regard to the video display signal of all monitoring subsystems being transferred in the pulpit and by the operator.
In the teaching of subjects such as medical science, biology, agronomy, forestry, materialogy, geology, be extensive use of the form of observation by light microscope micromechanism.When the student uses observation by light microscope, its visual field can only be seen for the student usually, the teacher has only allows the student suspend the content that observation just can be seen its optical microscope visual field, is unfavorable for that like this teacher instructs the interaction that single, part or school's observation by light microscope carry out real time bidirectional.
For solving this difficult problem, more existing technology are the images that install simulation CCD camera picked-up student optical microscope visual field on student's optical microscope additional, by the analog TV video transmission line with the analog TV video signal transmission of student's optical microscope view field image to the multi-channel video switch, after switching, be transferred to the image collecting device of teacher's computers again, be transferred to video projector's Projection Display through teacher's computers VGA output port, realize that with part the teacher instructs the interaction that single, part or school's observation by light microscope carry out real time bidirectional.When the imaging plane of the observation visual field of student's optical microscope and CCD camera inconsistent (promptly not parfocalization) (this is difficult to be avoided when using the object lens of different multiplying), the optical microscope view field image of teacher's computers display and video projector's Projection Display is just smudgy, influence the guidance of teacher to student's observation by light microscope, otherwise, the student can only be by observing the optical microscope view field image of video projector's Projection Display on one side, regulate the optical microscope focus knob on one side, make the optical microscope view field image focusing of Projection Display clear, can finish interaction with the teacher.When numerous students need interactive focusing, will occur regulating the situation of being obstructed, interactive communication effect is just had a greatly reduced quality.
