Definitions

  • Subscriber system with several subscribers formed by electrical devices and connector block for use in such a subscriber system
  • the invention relates to a subscriber system with a plurality of subscribers formed by electrical devices, each of which is connected via an interface to a common bus formed by optical waveguides.
  • various types of electrical and electronic devices are networked with one another and exchange information with one another via the common bus.

  • Device components that are used for extensive control and monitoring of vehicle functions can also be integrated into such a network. So that all participants in the system can communicate with one another, the bus is preferably designed as a loop in itself. Each subscriber component is therefore connected to an incoming fiber optic cable. cut and connected to an outgoing optical fiber section.
  • the incoming light signals are converted into electrical signals, evaluated and modified if necessary, and then converted into optical signals which are forwarded via the outgoing optical waveguide section.
  • the light path is therefore interrupted at each individual subscriber component and is bridged by the function of the relevant subscriber component with its interface containing the electro-optical converters with respect to the signal flow.
  • the interfaces each comprise a connector block, which has electrical contacts for connection to the associated device, an optical waveguide input and an optical waveguide output for insertion into the optical waveguide, and in that the optical waveguide input has an electro-optical converter For converting light signals arriving via the bus into electrical signals passed on to the electrical contacts and the optical waveguide output, an electro-optical converter for converting the electrical signals coming from the electrical contacts into light signals going out on the bus is assigned.

  • any subscriber component fails in a subscriber system with a closed bus, the signal flow on the entire bus is interrupted and the entire subscriber system can fail. This is a consequence of the monodirectional signal transmission from one subscriber component to the next, and because of the interruption of the optical signal path at each subscriber component, their perfect functioning must be assumed at least with regard to the reception and transmission of signals.
  • this problem is remedied by the fact that in the connector block the optical path between the optical waveguide input and the optical waveguide output is bridged when no electrical device is connected or is defective, and is interrupted when an electrical device is connected and is functional. At rest, i.e. if the device is not connected or the device is inactive, the optical waveguide is bridged within the connector, so that signal transmission is ensured.

If the device like this It is conceived that the control signal can only be emitted if at least its function of signal acceptance and signal transmission is guaranteed, the function of the entire bus system is not endangered by the failure of an individual subscriber component.

Abstract

Dans un système, plusieurs appareils électriques (10, 12, 14, 16) de divers types sont raccordés chacun par une interface à un bus commun constitué de sections de fibres optiques (18, 20, 22, 24) qui forme un anneau fermé. Chaque appareil est raccordé au bus par un bloc connecteur (30). Le bloc connecteur (30) comprend des contacts électriques de connexion avec l'appareil correspondant, une entrée de fibre optique et une sortie de fibre optique à insérer entre deux sections de fibres optiques (18, 20, 22, 24). Le bloc connecteur (30) contient deux transducteurs électro-optiques de conversion des signaux optiques arrivant par l'intermédiaire du bus en signaux électriques et des signaux électriques en provenance des contacts électriques en signaux optiques transmis par l'intermédiaire du bus. Afin d'assurer l'intégrité de l'ensemble du système de bus même en cas de défaillance d'un appareil, le trajet optique à l'intérieur de chaque bloc connecteur (30) est automatiquement ponté lorsque l'appareil raccordé est défectueux ou qu'aucun appareil n'est raccordé. Comme élément de pontage on peut utiliser un réflecteur de concentration (118).
