  • a device is known from Signal + Draht 84 (1962) No. 6, pages 166 to 171.
  • Level crossings vary in their topographical design in a variety of ways due to the number of tracks running over them, the switching means used to secure cross-traffic, the required switching behavior of these switching means and with regard to monitoring the level crossing; a distinction must also be made as to whether the activation of the level crossing, i. H . the activation of its security components, vehicle-operated by means of track switching means, or is carried out from a signal box or another control point.
  • a level crossing may also have to be temporarily or permanently adapted to new circumstances.
  • appropriate control software must be provided in the case of computer-controlled level crossing technology, which takes into account the individual projecting cases and can be adapted to new conditions if necessary.
  • the projection parameters are usually stored in a central software memory of the level crossing by means of a suitable input device, preferably by means of a computer. Because of the diversity of the topographical design of level crossings, the control software of computer-controlled level crossings varies more or less considerably from case to case. Every new level crossing and every change An existing level crossing requires an almost complete re-creation of the control software with the resulting requirements with regard to simulation, testing and ultimately also the creation of a safety certificate. The same applies to non-computer-controlled, exclusively or predominantly hardware-controlled level crossings.
  • the object of the present invention is to provide a device according to the preamble of claim 1, with which it is possible to adapt the control software of a level crossing to the given topographical requirements in a simple, manageable manner, the control software generated in this way being precisely because of its manageability only little elaborate safety evidence can be provided.

  • the linking logic provided according to the invention can each be constructed from a plurality of standard links, the number of these standard links being based on e.g. B. five different logic modules is limited.
  • the guideway objects, including their modules, and the assignment module are part of a computer or computer system which controls a level crossing or controls several level crossings.
  • the central assignment module which causes the switching components of a level crossing to be switched on and off and their monitoring, is to have a memory according to the teaching of claim 4, in which the interaction of the process periphery with the safety components of the level crossing, which is predetermined by the topography of a level crossing, is stored. This makes it possible to use a uniform assignment module for different level crossings and to adapt this assignment module to a specific level crossing by having the modules intended for the level crossing have very specific inputs of the assignment module or very specific address areas of the assignment module.

  • the level crossing is switched off via switch-off contacts AzA2 or AzA4 by the train passing the level crossing.
  • the safety components of the level crossing remain effective, ie the light-sign system blocks the level crossing against cross traffic and any barriers provided remain lowered. Only when the switch-off contacts are no longer actuated after actuation does the level crossing switch off after a specified delay time and the level crossing is released for cross-traffic. A prerequisite for switching off the level crossing is that the associated siding is not used at the time of switching off. There are no make contacts for the opposite direction. Rather, it is assumed here that the activation of the HpEl, HpE2

If the level crossing is not monitored, the signals ÜS1, ÜS2, Hpl or Hp2 block further advancement on the level crossing.
  • the driver of an approaching train then has to initiate braking, the initiation of this braking process also being able to be brought about by means of additional track switching means.

  • the switch-on contacts AzE2 are also actuated when a train is approaching the level crossing; However, the position stress of the turnout Wl is different from that of the previously assumed route 1. For this reason, the activation of the level crossing via the route object X3 is dependent on an AND operation Vu of the switch-on contact actuation AzE2 and the negation of the turnout position Wl +; the latter takes place via a negation element Vn.
  • the activation software modules E of these objects are controlled via standard linkage Va for the decoupled division of the traffic report and the point position stress on the two track objects; the standard links Va and Vu are cascaded.

  • This then causes the monitoring signal ÜS1 to be switched on in the further course of the route 3 via its software module Ü.

If the switch-off conditions are met, the switch-off software module A of the route object XI uses the assignment module Z to deactivate the safety components of the level crossing.

  • the switch-off of the level crossing depends on the presence of the peripheral message AI (e.g. AzA2 activated, delay time expired) dependent on the clearing of the access track used by route 2 on the level crossing. If the inlet track between the switch-on contacts AzEl and the switch-off contacts AzAl is released, the corresponding peripheral message El, in cooperation with the other switch-off conditions, triggers the switch-off of the level crossing.
  • the interaction of the switch-off conditions is realized by the AND link of the corresponding peripheral signals, each cascaded with standard links for the non-reactive division of the corresponding message for switching off the level crossing switched on via other routes.

  • the corresponding, interconnected AND-linked peripheral messages let the switch-off software module A of the route object X3 deactivate the safety components of the level crossing.

  • the aforementioned software modules are always and always the same; only the number of route objects and thus also the number of software modules for switching on, switching off and monitoring the level crossing and the number of software modules for controlling and monitoring the security components can vary from case to case.

  • This software is adapted to the topography of the level crossing to be controlled exclusively via the link logic, which in turn consists of a few standard links.
  • a control function of the same type as was explained above on the basis of a computer-controlled level crossing can also advantageously be used for hardware-controlled level crossings or mixed forms of hardware- and software-controlled level crossings.
  • the modular design of the control elements and the connection of these elements on the input side also result in a manageable structure of the control of the level crossing in accordance with the topography of the level crossing.

Abstract

Selon l'invention, la commande destinée à un passage à niveau (BÜ) est constituée d'une pluralité de modules d'une conception identique, appelés objets de voie (X1 à X5). Pour le passage à niveau il y a autant d'objets de voie que de voies (1 à 5) différentes qui peuvent être placées sur lui. Par l'intermédiaire d'une logique combinatoire (VL) constituée de simples opérateurs logiques standards (Vo, Vu, Vn, Vv, Va), le matériel périphérique de processus (P) peut chaque fois avoir accès seulement à l'objet de voie qui est affecté à une voie définie. Cet objet de voie peut, de son côté, par affectation individuelle, attribuer des messages de surveillance seulement à un signal de surveillance (ÜS1, ÜS2) affecté à la voie concernée. La mise hors circuit se fait aussi par l'intermédiaire de la logique combinatoire, exclusivement par rapport aux voies. Pour la commande des composants de sécurité (S) du passage à niveau, un bloc fonctionnel d'affectation (Z) commun reçoit ses instructions de commande des objets de voie individuels et transmet à ceux-ci des messages de surveillance. L'adaptation de la commande à différentes données topographiques et à différentes exigences fonctionnelles se fait exclusivement par l'intermédiaire de la logique combinatoire.
