Full Text	PCT/EP2005/054077 - 1 - 2004P13467WOIN Description Method and device for coordinated operation of vehicle doors of rail or track-based vehicles and corresponding platform control systems, in particular platform doors The invention relates to a method and a device for coordinated operation of vehicle doors of rail or track-based vehicles and corresponding platform control systems, in particular platform doors, which are in each case controlled by at least one central controller for a vehicle and at least one central controller for a platform, for vehicle systems with a radio- based vehicle control device. It is known for the doors of rail vehicles to be kept closed until the vehicle comes to rest, and for the doors then to be allowed to open, or for opening to be allowed, only by a central control unit. In modern train systems, in particular those with a large number of passengers and/or operation with few train and platform personnel, or even none at all (automatic train operation), it is also already becoming normal for the passengers on the platform to be protected by platform doors against an approaching train. A wall which is provided with doors is then located at the platform edge. Dangers resulting from the approaching train and stress on the passengers caused by the resulting wind of motion, noise, etc., can thus be precluded. It is also known for "immaterial" platform doors to be provided by specific marking of a line at a distance from the platform edge, which line must not be crossed over, as well as specially illuminated areas, or areas PCT/EP2005/054077 - 2 - 2004P13467WOIN identified in some other way, where the vehicle doors can be accessed once the vehicle has stopped. Various solutions are known in order to keep flexible platform door systems available and thus to allow adaptation to the tolerances of the door separations or to changing door separations of different vehicle companies. For example, EP 1 386 813 A1 discloses a platform door system having a row of platform doors. The corresponding platform doors can be opened by an opening command from the train, by transmitting a train identification signal at the same time as the opening command, which is used to select the platform doors to be opened, and their opening width. Furthermore, systems are known which are intended to allow the vehicle to be stopped at an accurate location and which allow opening of the vehicle doors and of the platform doors only when the precise position has been reached. Appropriate monitoring appliances on each door operate either by means of light barriers (JP 01311951 A), ultrasound transmission (JP 07112663 A) , induction loops (JP 2000071975 A) or radio (JP 54047207 A, JP 2002362367 A). Systems are also already known in which the intact or faulty status of a door can be transmitted from the vehicle to the platform, and vice versa, via the transmission path between a respective vehicle door and a platform door (JP 2001328531 A). The passengers at the respective faulty door can thus be informed of the status of the door in advance, and those at the corresponding door can likewise be informed immediately after the vehicle has stopped. This makes it possible to avoid unnecessary waiting in front of a defective door installation, and unnecessary operating and PCT/EP2005/054077 - 3 - 2004P13467WOIN unlocking attempts, which are always associated with the risk of damage to a door. In fact, it would be desirable to provide information even a certain time before the arrival of the train, in order in this way to specifically allow the passengers to be guided to a different door, at this stage. The object of the invention is to significantly further develop the already known vehicle/platform door systems, with regard to their convenience and flexibility. According to the invention, the object is achieved by the features of claims 1 and 8. Expedient refinements are the subject matter of the dependent claims. Accordingly, the door availability of the vehicle, as recorded by the respective controllers, and the availability of the elements of the corresponding platform control system are transmitted bidirectionally, before stopping at the respective closest platform, via a radio-based transmission channel between the vehicle and the platform, are preprocessed in the controllers, and are transmitted to the passenger information systems in the vehicle and on the platform. Provision is preferably made for the transmission channel between a train-side vehicle control device and a trackside vehicle control device to also be used - provided that it already exists - for transmission. Instead of platform doors, the advance notification can also be directed to other passenger guidance systems in which, for example, visual identification is provided on the platform in the areas of a door on the next approaching train, by lighting means (LED strips) incorporated in the platform, PCT/EP2005/054077 - 4 - 2004P13467WOIN or illumination of the appropriate platform edge area from above, traffic lights above the door areas, etc. A vehicle door which is not available could then be indicated by specific coloring (red) of the illumination and/or blinking. The timely mutual information about possibly defective vehicle or platform doors and/or platform control systems makes it possible to maintain operation even without any personnel involved, since the passengers can be reoriented in good time on the basis of the timely passenger information, so that the stopping times at the railroad stations are scarcely increased at all. In addition, the passengers can be prevented from manually trying to unlock doors which will not open. Different train configurations can be notified in good time, so that flexible platform door systems or flexible platform control systems can be prepared appropriately well before the arrival of the train, with the passengers being guided in good time, for example, only to those platform doors which will also be opened later after arrival of the train. In the event of major defects, for example if all of the doors of one car are affected, automatic, reduced train operation can be maintained by not only blocking the platform doors in this area but also by means of an automatically called-up announcement indicating the closed car. Furthermore, the advance notification can be passed on to transport facilities in the area around the platform, for example to the train station hall, to escalators and to feeder buses. The advance PCT/EP2005/054077 - 5 - 2004P13467WOIN notification may also be personal, by means of messages on cellular telephones, PDAs or smartcards. In addition to the information about the available doors, the advance notification may include further train-specific or door-specific features, including the train height above the platform edge, so that - if appropriate by means of an automatically called-up audible announcement - information can be provided about special features relating to entry and exit. Further passenger information, such as doors that should preferably be used for bicycles, strollers, wheelchairs or travel groups, can be provided in good time. Required entry aids (for example ramps for those in wheelchairs) can be moved into position in good time. Access to the vehicle doors which lead to a train restaurant or train bistro can likewise be especially identified by an automatically called-up announce- ment or in some other way, such as access to different travel classes (first class, VIP car). The advance information can also be used to selectively control the doors for specific events and facilities, in order in this way to separate entry and exit processes physically and/or in time, for example in order to speed up the change in passengers. The central door controllers may in this case also assess information coming from the central operational control, for example information about particularly large numbers of passengers to be expected at specific times at central events. If only one person is entering or leaving, it is possible to open only one individual door, and to automatically call up appropriate passenger information. PGT/EP2005/054077 - 6 - 2004P13467WOIN The individual door opening/closing is additionally handled locally in the already known manner, that is to say after the train has stopped by devices on the doors themselves, by means of which door opening or closing commands and further information are transmitted, such as the instantaneous door speed, trapping of objects or of passengers, and other fault states at that time. Known media such as infrared, transponders or data radio are used in this case. A device for carrying out the method according to the invention is predicated on the central controllers for the doors and/or the elements of a corresponding platform control system in each case being suitable for processing of data about the status of the doors or of the elements of the platform control system, and for interchanging the data bidirectionally via a radio- based transmission channel over relatively long distances between the vehicle and the respective closest platform. For this purpose, the transmission channel must be bidirectional. The door controllers are also connected to appropriate passenger information systems. It is preferable for the central controllers for the doors and the elements of a corresponding platform control system each to be connected to a train-side and a trackside vehicle control device, that is to say to be able to communicate with them and to be able to process data received from the opposite side, and to jointly use a transmission channel, which is provided in any case, between the train-side and the trackside vehicle control device. PCT/EP2005/054077 - 7 - 2004P13467WOIN The data paths which result when using the method according to the invention will be described on the basis of one exemplary embodiment, which is illustrated in an outline drawing. A vehicle control device ATP (Automatic Train Protection - ATP) is provided both on the trackside and on the vehicle side, and is used to control basic functions of the train, for example stopping at a specific platform position. The vehicle doors 3 of the train are driven centrally from a door control unit 1 (Train Door Control - TDC), and these access local door control units 2 (DCU) for each vehicle door 3. In the same manner, a platform-side door control unit 4 (Platform Screen Door Control - PSDC) controls local door control units 5 at corresponding platform doors 6. Even before reaching a platform, the two door control units 1 and 4 communicate with one another by jointly using the transmission channel 7 between the vehicle control devices ATP. Information about the status of the doors, vehicle doors 3 and platform doors 6, is thus transmitted in both directions in this way, and can be processed in the door control units 1 and 4, and in each case signaled to a vehicle-side and a platform- side passenger information system 8 (PIS_ts; PIS_ws). In this case, the trackside door control unit 4 can also take account of information from the central operational control ATS (Automatic Train Supervision - ATS) to which there is likewise a transmission channel 9.

Description
Method and device for coordinated operation of vehicle doors of
rail or track-based vehicles and corresponding platform control
systems, in particular platform doors
The invention relates to a method and a device for coordinated
operation of vehicle doors of rail or track-based vehicles and
corresponding platform control systems, in particular platform
doors, which are in each case controlled by at least one
central controller for a vehicle and at least one central
controller for a platform, for vehicle systems with a radio-
based vehicle control device.
It is known for the doors of rail vehicles to be kept closed
until the vehicle comes to rest, and for the doors then to be
allowed to open, or for opening to be allowed, only by a
central control unit. In modern train systems, in particular
those with a large number of passengers and/or operation with
few train and platform personnel, or even none at all
(automatic train operation), it is also already becoming normal
for the passengers on the platform to be protected by platform
doors against an approaching train. A wall which is provided
with doors is then located at the platform edge. Dangers
resulting from the approaching train and stress on the
passengers caused by the resulting wind of motion, noise, etc.,
can thus be precluded. It is also known for "immaterial"
platform doors to be provided by specific marking of a line at
a distance from the platform edge, which line must not be
crossed over, as well as specially illuminated areas, or areas

identified in some other way, where the vehicle doors can be
accessed once the vehicle has stopped.
Various solutions are known in order to keep flexible platform
door systems available and thus to allow adaptation to the
tolerances of the door separations or to changing door
separations of different vehicle companies. For example,
EP 1 386 813 A1 discloses a platform door system having a row
of platform doors. The corresponding platform doors can be
opened by an opening command from the train, by transmitting a
train identification signal at the same time as the opening
command, which is used to select the platform doors to be
opened, and their opening width.
Furthermore, systems are known which are intended to allow the
vehicle to be stopped at an accurate location and which allow
opening of the vehicle doors and of the platform doors only
when the precise position has been reached. Appropriate
monitoring appliances on each door operate either by means of
light barriers (JP 01311951 A), ultrasound transmission
(JP 07112663 A) , induction loops (JP 2000071975 A) or radio

Systems are also already known in which the intact or faulty
status of a door can be transmitted from the vehicle to the
platform, and vice versa, via the transmission path between a
respective vehicle door and a platform door (JP 2001328531 A).
The passengers at the respective faulty door can thus be
informed of the status of the door in advance, and those at the
corresponding door can likewise be informed immediately after
the vehicle has stopped. This makes it possible to avoid
unnecessary waiting in front of a defective door installation,
and unnecessary operating and

unlocking attempts, which are always associated with the risk

systems in the vehicle and on the platform.
Provision is preferably made for the transmission channel

already exists - for transmission.
Instead of platform doors, the advance notification can also be
directed to other passenger guidance systems in which, for
example, visual identification is provided on the platform in
the areas of a door on the next approaching train, by lighting
means (LED strips) incorporated in the platform,

or illumination of the appropriate platform edge area from
above, traffic lights above the door areas, etc. A vehicle door
which is not available could then be indicated by specific
coloring (red) of the illumination and/or blinking.
The timely mutual information about possibly defective vehicle
or platform doors and/or platform control systems makes it

A vehicle control device ATP (Automatic Train Protection - ATP)
is provided both on the trackside and on the vehicle side, and
