Definitions

  • Modern process control systems are used to monitor the operation of a technical system, to automatically carry out certain processes and functions in the system and to ensure that the system can be controlled safely in the event of a fault without causing damage to people and / or material.
  • Examples of such plants are power plants for generating electrical energy, production plants, chemical plants and many more.
  • a process control system usually comprises a computer system with viewing devices, for example screens, on which information about the current and / or historical and / or expected future operating state of the system is shown.
  • the operating personnel In order to perform its tasks, the operating personnel must be provided with information about the operating state of the system in the clearest, most well-prepared and easy-to-read representation by the process control system.
  • the process control system For this purpose, it is possible and known, for example, to display one or more information-bearing process images, which are stored in a computer of the process control system and which are updated during operation, on a screen and thus to make them accessible to the operating personnel.
  • the disadvantage here is that the screens that are usually used are very small, so that at the same time only a few people who have to be in the immediate vicinity of the screen can be informed about the operating state of the system.
  • a screen offers only limited space, so that the number of information that can be displayed is limited.
  • an additional computer means an additional source of error in the computer system.
  • large-screen projection systems in particular are mostly designed for operation under the UNIX operating system or derivatives thereof, so that use under the widely used Microsoft Windows operating system is not straightforward.
  • the invention is therefore based on the object of specifying a process control system with an image display system which is a simple way to divide and display a process image on several display devices.
  • the object is achieved by a process control system with an image display system, with which a process image can be divided into a plurality of display devices, the image display system comprising a graphics adapter which is capable of dividing the process image onto the display devices in an internal memory of the graphics adapter - to control mittein and the display devices for displaying the process picture each with the associated determined process picture division data.
  • a process control system makes the use of one or more multichannel image split computers superfluous, in that its functionality is taken over by the graphics adapter, which carries out the calculations in an internal memory which are necessary in order to use multiple display devices, in particular screens and / or images. Projection systems of any available projection area size, to be controlled in such a way that the display of a process image is distributed over the viewing devices.
  • the graphics adapter is advantageously a PC-compatible graphics card, preferably for use under the Microsoft Windows operating system, with at least three, preferably four, video channels and the graphics adapter-internal memory per video channel has a size of at least 32 MB.
  • the described number of at least three, preferably four, video channels implements the sizes most in demand by the market for a control system with an image display system;
  • the number of pieces of information that can be displayed on three or four display devices is sufficient to give the operating personnel a sufficiently detailed information picture of the operating status of the technical system without the operating personnel having to record the wealth of information. would be overwhelmed.
  • a number of three or four viewing devices for example screens and / or projection surfaces, represents an optimum in terms of the readability of the information from the screens when a typical process image is shown distributed on the screens.
  • the memory size of at least 32 MB is also a particularly suitable size in order to easily implement the “image split function” on the graphics card in its internal memory, preferably RAM memory, and a sufficiently high processing speed and / or a sufficiently fast image build-up in the display to reach.
  • the invention also leads to the use of an at least three-channel, preferably four-channel, graphics adapter with a graphics adapter-internal memory, which is capable of determining the division of a process image to be displayed on a plurality of display devices between the display devices and the display devices for displaying the process picture in each case to control the associated determined process image division data in a process control system which comprises an image display system with a plurality of display devices.
  • FIG. 2 shows an overview of particularly preferred arrangements of display devices and image resolutions in a process control system according to the invention.
  • the image display system 7 comprises four viewing devices 9, for example commercially available computer screens or modules of a large-screen projection system.
  • the viewing devices 9 can, of course, be as close together as their design allows, so that in each case only the smallest possible web remains between the image areas of the viewing devices 9.
  • a graphics adapter 9 for example a graphics card for a PC capable of running under Microsoft Windows, contains an internal graphics adapter memory S, in which the distribution of the representation of a process image on the display devices 9 is determined.
  • the graphics adapter 12 controls the display devices 9 with signals belonging to the determined division, so that a process image is shown distributed over the display devices.
  • a separate image split computer is not necessary in order to achieve the representation of a process image distributed over the display devices 9.
  • FIG. 2 shows particularly preferred arrangements of display units 9 in a process control system according to the invention: in FIG 2a, four display units 9 are arranged in a matrix consisting of two rows and four columns; for example, a total image area with a resolution R of 3200 x 2400 pixels can be achieved. In FIG 2b four display devices 9 are arranged in a row; for example, a total image area with a resolution R of 6400 x 1200 pixels can be realized. 2c shows the arrangement of four viewing devices 9 in one column, whereby for example a total image area with a resolution R of 1600 x 4800 pixels can be reached. Finally, FIG.
  • FIG. 2d shows the arrangement of three viewing devices 9 in one line, with which, for example, an overall image area with a resolution R of 4800 x 1200 pixels can be achieved.
  • the viewing devices from FIG. 2 can be moved as close together as possible, so that the remaining webs between the individual image areas are as small as possible.
  • the achievable total image areas previously shown in connection with FIG. 2 are based on a resolution of the graphics adapter of 1600 x 1200 pixels per channel. If there is a different resolution for each channel, for example 800 x 600 pixels or 1024 x 768 pixels, the resolution of the total area to be achieved in this way must be determined accordingly.
  • the image resolution of the channels of the graphics adapter is particularly preferably adjustable and / or changeable, so that a suitable overall image resolution can be selected depending on the use of the process control system according to the invention.

Abstract

L'invention concerne un système de contrôle de processus qui comprend un système de représentation d'image (7) permettant de répartir une image de processus sur plusieurs appareils de visualisation (9). Ledit système de représentation d'image (7) comprend un adaptateur graphique (12) qui est conçu pour déterminer la répartition de l'image de processus sur les appareils de visualisation (9) dans une mémoire (S) interne à l'adaptateur graphique et pour commander lesdits appareils de visualisation (9) de sorte qu'ils représentent l'image de processus au moyen des données de répartition d'image de processus déterminées pour chaque appareil.
