Problems solved by technology

Some industrial fields do not allow monitors to directly modify the content of the screen, but need to use a third party (such as a design institute) to modify the content of the screen, and then configure and download it through instrumentation and control engineers or DCS suppliers, which is time-consuming and labor-intensive. longer period

Embodiment

[0017] Such as figure 1 As shown, the method for pixel-level video configuration of the present invention includes the following steps:

[0018] (1) Dynamic video call:

[0019] Through the virtual KVM (VKVM) program, the many-to-many mapping and dynamic selection of virtual graphics cards and physical graphics cards is realized, and the call of the traditional DCS screen number is changed into the call of the virtual graphics card number, and the required virtual graphics card is dynamically selected in the physical graphics card. Number, realize the dynamic calling of video display output.

[0020] In the case of limited physical graphics card channels reserved by the video matrix (such as 20 physical graphics cards), in order to achieve the purpose of freely and dynamically calling about 200 display screens, the original video scheduling right is moved from DCS to the graphics card, that is, let 200+ Each display screen is pre-displayed in 200+ virtual graphics cards at t...

Abstract

The invention aims to disclose a pixel-level video configuration method, and compared with the prior art, the content holding of a DCS on a display picture output end is avoided, a plurality of existing single pictures are arbitrarily cut, and the cut images are arbitrarily spliced into a new picture in real time; according to the method, the processes of picture reconfiguration, downloading, publishing and the like through traditional DCS software are avoided, the display content of the existing DCS software is not damaged, and the purpose of infinite picture reconstruction is achieved through recombination of video sources of the display terminal; based on dynamic video calling of the virtual display card, cross-platform video output calling is achieved, limitation of fixed video output of a DCS platform is avoided, the video control right is transferred to the virtual display card and a corresponding driver to be achieved, and therefore infinite and intelligent display is achieved; the method can be applied to a main control room operation station VDU and a large-screen display system, the display content of a video terminal is enriched, the autonomy and flexibility of an operator are expanded, and the purpose of the invention is achieved.

Description

technical field [0001] The invention relates to a pixel-level video configuration method, in particular to a video and image-based dynamic calling and configuration method. Background technique [0002] Distributed Control System (DCS) is an important part of the industrial control field, mainly used for data acquisition, transmission and monitoring. A large number of DCS monitoring screens are used in the centralized monitoring room to display comprehensive information such as necessary process screens and alarms, so that monitoring personnel can know the status of the power plant in real time. The presentation of the DCS screen requires the help of a conventional video display unit (VDU) and a large-screen display, and the DCS configuration results are placed on the corresponding display terminals through video signals. [0003] The modification of the existing DCS screen requires the help of the DCS software itself to go through a series of processes such as data logic m...
