• the user interface enables him to control and / or regulate the traffic-influencing components located in his driveway area in accordance with the planned train sequence in his driveway area or also in accordance with the train sequence that deviates from the schedule due to delays and / or technical defects.
• traffic-influencing component is intended in the context of the invention described below can be seen comparatively far.
• Components such as turnouts, signals, speed indicators, warning signal generators, axle counters, magnetic rail contact detectors, train number detectors and, of course, individual assemblies of these components, such as, for example, turnouts, their turnout heating, direction indicators, lighting of the direction indicators and the like are immediately obvious.
• the traffic-influencing components include tunnel lights and fans, temperature sensors, access to locomotive and wagon depots, data transmission routes (e.g. tunnel radio links), timers, avalanche, flooding and rockfall sensors, voltage supply units, contact wire devices, level crossings, hot runner devices and flat points understood above components.
• the invention is therefore based on the object of specifying a traffic control center and a method for operating a traffic control center which make it possible to handle the entire data stream of the traffic-influencing components located within a travel route area and to be able to process it selectively with regard to the information requirements of the control center personnel.
• this object is achieved in that a) the traffic-influencing components for receiving and / or sending data are connected to a master computer; b) in the master computer, the data received from the components influencing traffic can be compared with the data last received from the respective component; c) data or parts of data which differ from the data last received can be sorted out as update data; and d) user-definable data subscriptions are provided which only access certain update data defined in the respective data subscription.
• This task is carried out with regard to the method for operating a traffic control center which is to be operated by means of a
• the user interface can be used for the control-related handling of traffic-influencing components that are arranged along a traffic route for traffic vehicles, according to the invention solved in that a) the traffic-influencing components for receiving and / or sending data are connected to a host computer; b) the data received from the components influencing traffic are compared in the host computer with the data last received from the respective component; c) data which deviate from the data last received are marked as sortable as update data; and d) data subscriptions are defined which only access certain update data defined in the respective data subscription.
• a traffic control center which receives the entire data stream by means of the host computer and reduces it to the part which is relevant for further processing due to a data change that has occurred in comparison with a stored database.
• the host computer is not meant exclusively as a computer that is also physically located in the traffic control center, but can also be divided into subcomputers, with subcomputers, for example, being able to be arranged directly at a component that influences traffic and only provide the data relevant for further processing send the sub-computer assigned to the traffic control center.
• the traffic control center can select very selectively which of the data relevant for further processing (update data) to satisfy the current information needs of the control center personnel must also be communicated to the control center personnel or otherwise processed.
• a particularly high selectivity in the selection of the information that is basically and / or currently just required for the traffic control center personnel can be achieved if the data subscriptions can be assigned to certain monitoring, control, regulation and / or display procedures.
• the certain procedures in the background regardless of the sequence of the procedures Define the required data and generate it according to the associated subscription process.
• a particularly simple procedure with regard to the management of the update data results if the update data can be transferred to an update data memory in the sense of their sorting out. In this way, the data subscriptions need only have corresponding search mechanisms with which they can search for the update data relevant to them in the update data memory.
• the Aktualisier poems named can in this case in the form of a continuously updatable file or a separately addressable storage medium such as a memory 'in a host computer, have been created.
• a particularly advantageous solution can provide for the update data to be managed in a LAN network. This procedure is based on the fact that the various processes based on data subscriptions log on to the host computer when they start up and tell the host computer exactly that update data are part of their application-specific data subscription. It is the task of the host computer to manage an assignment list of the update data and thus to manage the dispatch of the update data to the respective processes.
• An expedient embodiment of the invention can consist in the fact that the user interface is a permanently installed computer workstation provided with data display devices and / or a portable input / output terminal with display unit.
• the portable design allows commands for the adjustment of traffic-influencing components to be issued directly on site and to be confirmed by the operating personnel at the computer workstation and subsequently also to be confirmed symbolically on the display unit or as a text output.
• the traffic control center constructed in this way thus allows, for example, the setting and / or blocking of routes on site for shunting, Maintenance and / or repair purposes, provided that safety-related restrictions and the complexity of the traffic area to be monitored by the dispatcher allow this.
• a construction site manager can operate such a portable terminal as needed to temporarily block a certain switch or a certain section of route.
• a shunting master In shunting operation, it is also possible for a shunting master to have a specific shunting area activated by the traffic control center and thus operate this shunting area independently from the traffic control center. This marshalling area can then be marked as occupied in the traffic control center. The display of the current status of switches, signals and other components that are located in this shunting area released by the traffic control center can be found in the
• a mobile terminal with a user interface and display unit arises if the technical representation of the condition of a traffic area in a locally effective signal box without a locally available user interface is desired, for example for maintenance purposes.
• the high functionality of the traffic control center allows the mobile terminal to be attached to the central control technology process via routing via an ISDN connection, to define a data subscription and consequently to receive the data required for the desired application.
• the data received from the host computer of the respective traffic-influencing component is a data string which all characterize the component in relation to its intended task Contains information. So that will also supports the possibility of having to provide only a single, centrally arranged master computer.
• a very particularly advantageous property of the traffic control centers according to the invention can be exploited if user-definable data subscriptions are provided which only access update data relevant for the display in the user interface.
• the information needs of the dispatcher can be served particularly well and clearly if the current status of the traffic-influencing components can be represented in the user interface and the execution of a command that can be entered on the user interface for the adjustment of at least one traffic-influencing component can be confirmed acoustically and / or optically in the user interface is by securing this confirmation by accessing an update date that can be generated after the respective component has been adjusted and confirms the adjustment.
• the data subscription can be defined in such a way that access to only a single or very little update data is required, which also keeps the data stream to be controlled in the user interface extremely low.
• the current traffic situation can be recorded directly by the dispatcher if the update date is processed in a meaningful manner in the user interface.
• the traffic-influencing components can be categorized into certain types and corresponding type-specific data subscriptions can be provided. This simplifies the work of the dispatcher or other persons in such a way that these type-specific data subscriptions allow specific information to be obtained only about a specific component type and about the changes that are currently taking place with this component type.
• the image of such a type-specific data subscription can thus run, for example, even without a special representation as a background process and can only be activated and displayed in the user interface when there is special need or at defined periodic intervals or in the course of another process control process at predetermined times.
• the data originating from the traffic-influencing components are categorized into specific groups that represent the operating state of the components and corresponding group-specific data subscriptions are provided.
• group-specific data subscriptions can, for example, be the starting point for the maintenance and / or repair of certain components by first querying for which components a status change from "intact" to "faulty” has taken place in a definable past period. The search for failed lamps or defective electric point heaters is an example of a maintenance process.
• Another process that can be operated with a data subscription can also be, for example, the monitoring of the rolling stock for hot runners and / or flat spots. Only if one locates the hot runner and / or the flat spot
• an update date can be generated, the occurrence of which, for example, becomes the trigger date for the start of another process with data subscription.
• This process can now provide for the current update data to be loaded from a nearest axle counter in connection with a nearest train number detector, for example a Euro-Balise, in order to provide the maintenance personnel with the information required to identify the faulty bearing and / or wheel.
• a nearest train number detector for example a Euro-Balise
• the response of a hot runner detector in particular can also immediately trigger an alarm in the traffic control center, which gives the dispatcher the opportunity to stop this train with a defective axle immediately or at a next suitable stopping point.
• Another embodiment of the invention which is particularly useful for road users, allows a data subscription to be defined which accesses update data which are intended to inform road users. It is conceivable that passenger information displays are provided at the stops and / or platforms, which indicate the expected arrival times of the trains / buses.
• the relevant data subscription specifically accesses the data of train number detectors, which become update data due to the fact that a specific train has now passed a specific position.
• This data subscription can also be used, for example, to supply an Internet-based information service with the corresponding data.
• This information service can allow the road user to be informed when a particular means of transport is likely to arrive at a certain stop due to the current traffic situation. Relevant advertisements in train stations are already known, but the information supply for these advertisements is based on the telephone transmission of this information by the personnel of the transport company.
• the figure shows a schematic representation of a traffic control center VLS, such as is used in rail-bound traffic in the area of large train stations and / or metropolitan areas.
• the traffic control center VLS has three computer workstations designed as a user interface with data display devices for one or more dispatchers. These workplaces are referred to below as dispatcher positions FD.
• Another work station serves as a supervisor work station S, which is equipped in terms of hardware like the dispatcher work stations FD.
• the supervisor work station S and the dispatcher work stations FD are connected to a LAN network NW for data exchange, via which all traffic-related data traffic is processed.
• a LAN network NW there are also an announcement point A, a protocol printer PD, a schedule office FPB and a
• a connection to the LAN network NW has: a data line for the bidirectional connection of the traffic control center VLS to an adjacent traffic control center NZ, in each case a data line for outputting data to a superordinate dispatch center DZ, to a train control center ZK and to a maintenance center U, and a data line for receiving data from a radio center FZ and a system clock SU.
• the master computer LR is therefore shown in a distributed manner, because virtually every connection from the LAN network NW to a component that sends and / or receives data is initially made via the master computer LR.
• the concept of the host computer LR is therefore to be considered more abstractly, because computers assigned to the components can also take over functions of the host computer LR.
• This conceptual design of this type is also made clear by the connection of computer-assisted interlocking functions StwF and automatic functions AF and by the connection of relay-assisted interlockings RStw controllable via a remote control system RCS to the LAN network NW and the coupling of one Remote maintenance FW using an ISDN connection and a router.
• the first measure here provides that all data originating from a component VKl, VK2 that influences traffic are first checked for changes in the data compared to the data last sent by components VKl, VK2 that influence traffic.
• Data (D) that have changed are identified as update data (AD) and are thus "stamped" for later selection.
• this can be implemented, for example, by separating this data from the other data by setting a Boolean variable from "FALSE" to "TRUE” using a process that searches for data with this Boolean variable equal to "TRUE” , Such update data marked with the "TRUE” flag are then fed into the LAN network NW and administered there.
• the second special measure now consists in the fact that user-definable data subscriptions are provided which only access certain update data that are desired by definition. Such data subscriptions virtually determine for each component that has properly logged on to the LAN network NW, which update data should be sent to which address via the LAN network NW and processed there in its own process.
• the FD stations require all update data that change the route situation displayed on the visual display devices.
• An example is the acknowledgment message of a turnout, which confirms that a turnout tongue after a
• Dispatcher station FD process currently running only the arrival of this acknowledgment message interesting. All other data transmitted by this turnout either have not changed (and are therefore uninteresting) or, if other data have also changed, these changes are for the currently running process (display of the turnout setting according to an adjustment specification) at the dispatcher's station Not to use FD by definition.
• the traffic control center VLS described is of course also suitable for supporting the monitoring, control and / or regulation of traffic-influencing components which, for example, monitor, control and control individual road traffic, public transport and air traffic / or regulate.
