Definitions

  • the invention relates to a communication system for radio operation according to the preamble of claim 1 and is applicable, for example, for rail services.
  • the radio driving mode is a new operating procedure, which realizes the functions "route setting” and “route protection” on the vehicle and not on the route as before.
  • One problem is the limited resource of radio channels from the vehicle to the route and the associated long connection setup times (20-25 sec including the establishment of the data link layer).
  • Radio communications are carried out simultaneously by the vehicle.
  • the intended radio standard for rail applications provides only one radio channel for data communication per terminal. Even if two mobile radio devices are used on the vehicle, bottlenecks can occur.
  • a communication device for radio-based railway services is known, with which both the data from decentralized control devices and the data from central services can be transmitted to a train with only a single transmission channel. For this purpose, all of this data is to be fed to a central gateway computer. This then initiates the data transmission to the vehicle.
  • a central gateway computer which is assigned to the train, it is possible to transmit all data in the multiplex without a new transmission when the train advances by changing to a new route area. line between the train and the central rail services.
  • an optimized communication system for radio-based traffic services is described, which in addition to the fixed central services and the fixed decentralized control points in the traffic network has one or more decentralized gateway computers.
  • Communication between the mobile instances and the fixed instances is realized via the gateway computers by a representative instance for the mobile instances that communicate with the gateway computers and in the gateway computers and in the stationary instances, and for the fixed instances that with the gateway computers communicate, proxy instances are set up directly in the gateway computer or indirectly via at least one information server.
  • the proxy information in the gateway computer and in the fixed instances is updated via an update procedure between the proxy instances in the gateway computer and the fixed instances or between the gateway computer and information server.
  • This method enables the multiplexing of several logical connections from one vehicle via a physical radio channel to a fixed network gateway, which can forward the connections to any endpoints within the fixed network.
  • the invention has for its object to provide a communication system for radio operation, which enables simple data reliable data traffic via effective communication paths with only one radio transmission channel between vehicles and track elements, the simultaneous communication with several track elements ensures and minimizes the effort for system setup, system update and system maintenance.
  • a particular advantage of the invention is that a single mobile terminal on a vehicle is sufficient to be able to communicate with a plurality of route elements at the same time, in that the radio-technical connections for data transmission from the vehicles to the route elements are not established directly, but are transmitted via a gateway computer become .
  • the price for this is that radio communications are required for communication with n track elements (n + 1). Without multiplexing, n radio communications are required for this.
  • Another application of the gateway functionality for radio operation on two-track or multi-track routes is to generally communicate with level crossings via the gateway computer. This is the only way that two or more trains can communicate with the level crossing at the same time. Without a gateway computer, this would have to be done one after the other and can lead to operational disabilities.
  • Another advantage of the method is that immediate instructions that are sent to the vehicles by radio from the radio control center can be immediately transmitted via the multiplex channel even in areas with a high track element density. This also applies to high-priority data that is broadcast to all instances of the multiplex channel at the receiving end.
  • the invention will be described in more detail below on the basis of an exemplary embodiment shown at least in part in the figure. It shows:
  • Figure 1 shows a variant of a multiplex connection vcr. Vehicle to the head office and the transfer to route elements
  • FIG. 1 illustrates the mechanism using an example of a route section consisting of two switches W1, W2 and a level crossing BÜ.
  • a route section consisting of two switches W1, W2 and a level crossing BÜ.
  • connection setup to the route elements Wl, W2 or BÜ can be optimized in this way.
  • the three communications would have to be carried out one after the other without multiplexing. Multiplexing allows communication phases of the individual communications to take place largely overlapping in time.
  • T (GSM) approx. 10 sec tm or approx. 5 sec moc
  • mtc b) construction of the data link layer
  • mtm mobile to mobile call (from one mobile to another)
  • moc mobile originated call (from mobile to ISDN landline)
  • mtc mobile terminate call (from ISDN landline to M'bile)
  • the total communication time is:
  • the multiplexing via gateway computer is completely transparent for the radio driving operation application; i.e. it is not visible which way the connection is conveyed.
  • the telegrams do not differ from telegrams that are transmitted directly (without the detour via the gateway computer) to a route element.

Abstract

L'invention concerne un système de communication destiné au mode de fonctionnement radio et elle s'applique notamment aux services d'entretien de la voie. Selon l'invention, on peut communiquer simultanément entre les sous-systèmes suivants: véhicule, éléments de ligne et centrale. Les liaisons de radiocommunication destinées à la transmission de données ne sont pas établies directement mais par l'intermédiaire d'un ordinateur de transit.
