  • Instructional features software 110 allows users to specify the types of functions they want to perform using the trainer. It is important to note that all user interfaces are accomplished using the touch screens 98. This is a significant advantage over previous automated simulators in which the primary user interfaces were accomplished using a character based terminal with keyboard. The advantage of this approach is that people unfamiliar with keyboards will not be confused by having to use them. A significant portion of the users of industrial process equipment do not read well, and the use of a touch screen will be much simpler for them than typing on a keyboard. The user interfaces handled by instructional features software are described in more detail in connection with FIGS. 5 - 7.

  • Procedure monitor software 120 receives device inputs from line 102 which indicate actions which the student has taken.
  • Procedure monitor uses a special type of database called "courseware" (not shown) , which specifies the actions that the student is expected to take.
  • courseware may specify that instructional graphics and audio presentations be made to the student.
  • procedure monitor software will make requests for the presentations to be made.

At certain points the courseware may also specify that environmental conditions (such as temperatures and pressures) change, or malfunctions in the equipment appear or disappear. Based on the courseware procedure monitor 121 will make requests to simulation to respond to environmental parameters and malfunctions.
  • the condition monitor request processing software 130 receives requests from the procedure monitor 120 along line 132 to monitor for occurrence of a state in simulation and receives reports of simulation states from simulation 128 along line 134. When a simulation state has achieved the state desired by the procedure monitor 120, the condition monitor request processing software 130 indicates events completion status to procedure monitor 120 along line 136. Further details of the procedure monitor 120 and condition monitor request processing 130 can be found in the related U.S.

  • text and graphic display commands are communicated along line 138 to simulation graphics 140 provide further visual cues.
  • Courseware graphics software 142 receives requests to display instructional graphics from the procedure monitor along line 124. These instructional graphics are authored off-line and stored in a database which specifies the appearance of the instructional displays. The courseware graphics software decodes this database and generates primitive graphics requests to display the graphics which are transmitted through line 144 to a graphics monitor driver 146.
  • Audio processor software 148 receives requests to generate tones and play digitized audio from the procedure monitor and simulation software. These sounds reflect sounds made by the actual equipment being simulated and also includes instructional materials narrated by humans. The audio processor software then generates audio signals along line 150 which are transmitted to speaker 152.
  • Simulation graphics software 140 transforms high level simulation graphics requests from simulation 128 into low level graphics primitive commands and requests graphics device drivers such as 146 to display the graphics.
  • the primitive graphics requests are transmitted along line 154.
  • Video disk controller software 156 receives commands from Glass I/O 96 to move the video disk player (not shown) and produces the necessary commands along line 158 to stimulate a video monitor 160 to produce the appropriate still or motion video.
  • this still or motion video will depict selected portions of the simulated equipment which may include for example the views shown in FIG. 8 as described below.

  • FIGs. 5 - 7 simplified diagrams in these figures depict the user interf ce controlled by the instructional feature software 110 which are used to initialize the invention for simulated equipment operation. It should be noted that the user interfaces are authored in a manner similar to the way the databases for the Glass I/O and courseware graphics are authored and can be easily changed to reflect the needs of different users.
  • a "procedure” is defined as a step-by-step instructional sequence, as previously discussed in the description of the procedure monitor software 120.

Abstract

Système (10) de formation interactif permettant de simuler les machines et les traitements industriels. Ce système (10) peut fonctionner en mode libre ou en mode de traitement, il comprend plusieurs écrans d'affichage (160, 168) qui simulent des images représentant des machines et des traitements industriels. On utilise des segments de recouvrement graphique pour simuler l'aspect des écrans d'affichage et les commandes manipulables situées sur les machines. Pour simuler la mise en oeuvre des vraies commandes, l'utilisateur emploie les segments de recouvrement graphique en touchant des écrans tactiles (24, 98). Un logiciel (96) d'entrée/sortie de l'unité de visualisation commande l'entrée de l'écran tactile et la génération de l'affichage. Un logiciel de simulation (128) commande les commandes qui génèrent les sorties sonores et visuelles simulées. Un logiciel (120) de surveillance du traitement spécifie les présentations qui devront être faites en fonction du didacticiel stocké à l'intérieur. Ce système (10) peut être utilisé par un utilisateur au moyen de l'écran tactile (24) seulement et ceci permet d'éviter d'utiliser un clavier. En outre, ce système de formation permet de réduire les coûts de formation et de production étant donné qu'il ne nécéssite pas d'utiliser les machines et le matériel industriels.
