A simulator dcs multi-screen visual recording and broadcasting management device

Abstract

The invention discloses a simulator DCS multi-screen visual recording and broadcasting management device, which includes a main control room, and the main control room includes four sets of OWP operator stations, and each of the four sets of operator stations consists of five thin machine clients and five monitors The DVI output ends of five thin computer clients are electrically connected to D‑DVI‑104 DVI video splitter, and the DVI signal is divided into three outputs, one of which is through the G‑DVI‑F400 DVI video optical fiber remote transmission device It is electrically connected to the multi-screen monitoring screen wall in the teaching control room, the other DVI signal is electrically connected to the operator station terminal display, and the last DVI signal is electrically connected to GeFen EXT‑DVIKVM‑841DL 8 / 1 KVM video switcher. The invention realizes the requirement of recording 4 groups of DCS screens at the same time, which is convenient for teachers to observe the detailed operation of the DCS screens of each group of students. By tracking the mouse track as the control signal of video output, a large number of image processing equipment is reduced in the back end, and the hardware cost is reduced. , also reduces hardware failure points.

Description

technical field [0001] The invention relates to a recording and broadcasting management device, in particular to a simulator DCS multi-picture visual recording and broadcasting management device. Background technique [0002] Under normal circumstances, the DCS operation screen monitoring system of the nuclear power simulator needs to connect all the DCS screens in the main control room to the encoding device through the video remote transmission device for data format conversion, and then send them to the recording and broadcasting server for synchronous recording, so as to realize online playback by teachers The operating conditions of the trainees on the simulator, and the teaching situation of the simulator can be called on the network in the form of computer multimedia files, and the training courses can be analyzed and judged. [0003] However, the existing multi-screen monitoring system cannot meet the requirements of recording 4 sets of DCS images in real time at the...

Problems solved by technology

[0003] However, the existing multi-screen monitoring system cannot meet the requirements of recording 4 sets of DCS images in real time at the same time, and can only record 2 sets of DCS images at the same time. If it is necessary to record 4 sets of images at the same time, it is necessary to increase the corresponding number of encoders, resulting in cost The increase in hardware also increases the failure points of the hardware. The original technical solution achieves the purpose of manual switching through the matrix switcher, which cannot track the current operation interface and automatically switch the output to achieve simultaneous recording of 4 sets of DCS screens. It is necessary to realize the visualization of DCS screens Recording and broadcasting needs to consider a lot of back-end image processing equipment, which is not only expensive, but also not conducive to system maintenance. Combining the defects of existing technical solutions, a simulator DCS multi-screen visual recording and broadcasting management system is proposed
