  • these screen elements are usually controlled by an image split computer, which determines the distribution of an image to be displayed on the individual screen elements.
  • the images represented by these systems are difficult to read if the light brightness in the power station control room is relatively high (which is usually desirable for reasons of a safe operating procedure) and / or daylight and / or stray light falls on the screen elements.
  • the object of the invention is therefore to provide a power station control room with a large-screen visualization system which can be used flexibly - particularly with regard to the space required for assembly - and which can be produced cost-effectively and which overcomes the disadvantages of known systems.
  • the object is achieved by a power station control room with a large image visualization system which comprises at least one projection system and at least one projection surface which is designed as a hologram.
  • a power station control room of this type makes it possible, for the information of the operating personnel, to display large images on a projection surface of almost any size which has no webs by which the partial images forming an overall image would be separated from one another.
  • the readability of the image is significantly improved.
  • the image quality is significantly improved through the use of a hologram and the sensitivity to incident daylight and / or artificial room lighting and / or stray light is significantly reduced, so that the legibility of the image projected onto the hologram is almost independent of the external lighting conditions.
  • the projection surface can be mounted practically anywhere in the waiting room where little space is required, since the projection surface is usually only a small thickness and the projection system is advantageously arranged on the ceiling of the waiting room.

  • the hologram is designed in such a way that such light can be used to generate an image representation on the projection surface which is projected onto the projection surface at a predetermined angle.
  • the hologram is designed such that light which is at an arbitrary angle is not equal to the predetermined angle strikes the projection surface, can pass through the projection surface largely unhindered.
  • the projection surface at the points where no image is projected is practically transparent, so that the operating personnel can also use and view the space behind the projection surface at the points, e.g. For attaching display instruments that should be readable and that are not covered by the image projection.

  • the space required for the assembly of the large image visualization system 7 is small, since the projection surface 12, as shown in FIG. 1, can be attached to the ceiling, so that the space in the area of the floor of the power station control room 5 remains free. This is particularly easily possible because the projection surface 12 has a small thickness and a low weight. Furthermore, the projection system 9 is arranged behind the projection surface 12 very close to it, directed towards the rear thereof, so that the space requirement is further reduced. It is also not necessary to keep a larger space accessible behind the projection surface 12, for example in order to be able to carry out maintenance on the projection system 9; The projection system 9 is advantageously suspended from the ceiling of the power station control room 5.
  • the image quality of the large-screen visualization system 7 of the power station control 5 according to the invention is higher, particularly with regard to the image contrast to be achieved, than with known large-screen visualization systems used in power station control rooms.

  • the associated projection systems, which illuminate the projection surfaces 12 on the rear side to produce images 15, are not shown in FIG. 2.
  • the thickness of the projection surfaces 12 is very small, so that the space required for mounting the large image visualization system 7 is very small and also one with regard to their spatial Licher dimensions small power station control room 5 can be equipped with a large-screen visualization system 7 according to the invention.
