Definitions

  • the present invention relates to a method for error disclosure in a control and / or monitoring device for a process, in particular for the control and / or monitoring of rail vehicles on a rail network, prepared in the derived from the process information on a display device for a process control center workstation become.
  • Such methods are found in a variety of commercial and industrial processes. Exemplary and without any claim to completeness are the processes of traffic control in the air, on the road, on the rail and on the water, building automation, energy production in fossil-fired and nuclear power plants, but also in power plants with regenerative energies, energy distribution and energy To call process control in manufacturing plants of all kinds.
  • a method for ensuring the signaling security of the user interface of a data processing system in which a process image is displayed on the user interface via a display system using two independent computers of the data processing system and user commands for influencing the process via an operating device can be entered. It is in the According to the disclosed method, a first computer receives a first external information from which it generates an image corresponding to the state of the process and displays it on the display system. The second computer is supplied with a second external information, from which it generates a relevant for a safety check second process image. Furthermore, when user commands are input, the second computer checks the user commands for their admissibility by comparison with the second process image relevant for the security check. If there are no user commands, the second computer compares at predetermined intervals the process image corresponding to the process represented by the first computer on the display system with the second process image and verifies this with the same statement.
  • the comparison of the first and second process image is carried out by software in the background of the user interface.
  • the second computer checks whether the elements associated with the user command are even in the desired manner.
  • the comparison of the process images is therefore limited to purely software-programmable, executed in the background arithmetic operations. Errors in these programmed arithmetic operations can therefore lead to the fact that the comparison of the two process images is indeed verified or not verified, but that actual other conditions prevail in the actual process, which could give rise to concern from a safety-relevant point of view. Similar effects could therefore also have much more complicated procedures for error disclosure, as these, for example, from the European Patent 1,050,815 are known.
  • the present invention is therefore based on the object to provide a method for error disclosure, in which the Risk of errors in the process image due to software errors in the information evaluation is further reduced.
  • control data representing the process image into corresponding graphics elements and by a superimposed representation of the graphic elements thus obtained on the display. It is therefore not necessary to determine a computational image of the process by software, but only to display the states of the individual elements in the form of the control data converted into graphic elements and thus differences of the superimposed graphic elements and thus differences in the Obviously visualizing the interpretation of the process state.
  • the graphic elements can be superimposed congruent and displayed transparently.
  • the differences in the overlaid graphics elements lead to smear or blur effects in the presentation that manifest themselves to a viewer to the user.
  • the graphic elements generated for the same element involved in the process can be successively linked to an XOR operation and the result of the link can be displayed.
  • the graphic element of a first logical channel is drawn on a plain-colored background. This new background is linked to the graphic element of an associated second logical channel by an XOR operation.
  • a first color e.g. in green color
  • all mismatched pixels of the graphic elements in a second color e.g. in red
  • a status display for the respective logical channels can be generated in such a way that only a part of the control data that can be assigned to each logical channel is displayed congruently overlapping , In this way, the presence of several logical channels, for example the presence of the required at least two logical channels, by an optically detectable union amount, the out-of-range optically divergent border areas each represent the one or the other logical channel to be displayed.
  • FIG. 1 shows a first schematic illustration 2 of the graphic elements G1, G2 originating from two sources Q1, Q2, which are displayed in a congruently overlapping image D on a data display device not shown here. It is easy for a user of the data display device to see from the illustration D that the messages from the sources Q1, Q2 (ie from the two logical channels) and thus also the graphic elements G1, G2 are not consistent.
  • the source Q1 reports that the switch 56 is individually locked.
  • the overlapping numbers 6 and 7 in Figure D lead to a blurred, smeared visual image at this point, which is manifestly revealed to a viewer.
  • the graphic elements G1, G2 are shown in FIG. On the display then appears only the representation D, which here discloses the error here.
  • FIG. 2 shows a second schematic illustration 2 for the illustration D.
  • the left-hand diagram shows an error disclosure by color differences in the superimposed graphic elements G1, G2, here again the texts “Switch 56 individually locked” and “Switch 57 individually locked”.
  • the different colors are only recognizable as different shades of gray.
  • the right-hand graph of FIG. 2 shows the case in which considerable importance can be attached to the error disclosure by the color resolution. If the graphic elements G3 "switch 53 individually locked” and G4 "switch 58 individually locked” overlap, the different numbers 3 and 8 in the cumulative representation could merge to form an "8". The underlying error would perhaps not even be perceived. Otherwise, this error is now apparent by the different color of the difference between the numbers 3 and 8 obviously.
  • FIG. 3 shows a schematic representation for indicating the availability of two logical channels. It is in the left graph in the upper right corner shows a not completely overlapping representation D 'of two rectangles R1, R2, which respectively correspond to the presence of a logical channel.
  • This representation D ' is shown enlarged in the right-hand illustration of FIG.
  • An overlapping area B is marked here with the darkest gray level.
  • a colored representation of this overlapping area could be shown, for example, in green color, the out-of-range areas, for example, in red. Only if the green inner rectangle is present can the user of the display device assume that the displayed data has been obtained from at least two logically independent data source and / or data sources.
  • the present invention ensures that safety-relevant information can actually be displayed in a secure, reliable manner for controlling and / or monitoring a process in a viewing device of a control room or the like. Therefore, in order to determine whether the display is safe, the purely visual comparison of the graphics elements obtained on a logically independent basis is sufficient in order to reveal any errors in the display and / or the lack of logical multi-channeling.
