Arrangement and method for controlling train platform doors

Abstract

The invention relates to an arrangement for controlling train platform doors of a platform, comprising a door control unit on the platform side for controlling the opening and closing of the train platform doors and means for establishing a communication connection between the door control unit on the platform side and a control unit which controls the opening and closing of the train doors, wherein independently of the communication connection operating means are provided for detecting the correct stopping of a train at the platform, wherein independently of the communication connection operating means are provided for detecting the opening and closing of train doors of a train stopping at the platform, wherein means are provided for recognising a malfunction in the communication connection between the door control unit on the platform side and the control unit which controls the train doors, and wherein the door control unit on the platform side is designed to control the opening and closing of the train platform doors independently of the communication connection.

1 . Arrangement for controlling platform doors of a platform, comprising
 a platform door control unit for controlling the opening and closing of the platform doors, and   means for establishing a communication link between the platform door control unit and a control unit that controls the opening and closing of the train doors,
 characterised in that 
   means for capturing the correct stopping position of a train are provided on the platform and function independently of the communication link,   means for capturing the opening and closing of train doors of a train stopped at the platform are provided and function independently of the communication link,   means for detecting a malfunction in the communication link between the platform door control unit and the control unit that controls the train doors are provided, and   the platform door control unit is designed such that it is able to control the opening and closing of the platform doors independently of the communication link with the controller for controlling the train doors.   
     
     
         2 . Arrangement according to  claim 1 , characterised in that means for outputting a wait signal for the train are provided, and are controlled by the platform door control unit. 
     
     
         3 . Arrangement according to  claim 2 , characterised in that the means for capturing the opening and closing of train doors that function independently of the communication link include at least one of the following means: a camera, a laser range finder, a laser scanner, a microphone, an ultrasound transceiver, an RFID chip reader unit. 
     
     
         4 . Method for controlling platform doors on a platform, including
 launching the establishment of a communication link between a platform door control unit and a control unit that controls the train doors of a train that is standing at the platform,
 characterised by 
   detecting the halt of the train in the correct position at the platform independently of the communication link,   detecting the opening and closing of the train doors of the train standing at the platform independently of the communication link,   determining the presence of a fault in the communication link between the platform door control unit and the control unit that controls the train doors and, if a fault does exist in the communication link,   controlling the opening and closing of the platform doors on the basis of the detected opening and closing of the train doors.   
     
     
         5 . Method according to  claim 4 , characterised by the generation of a wait signal for the train for as long as the platform doors are open. 
     
     
         6 . Method according to  claim 5 , characterised in that the opening and closing of the train doors is captured by scanning the train doors with a laser, preferably by means of a laser scanner that scans an angular or surface range. 
     
     
         7 . Method according to  claim 6 , characterised in that the opening and closing of the train doors is captured by analysing video images of the train doors. 
     
     
         8 . Method according to  claim 7 , characterised in that the opening and closing of the train doors is captured by ultrasound runtime measurement and/or by analysing an acoustic signal and/or by evaluating the signals from RFID chip reader units. 
     
     
         9 . Method according to  claim 8 , characterised in that the opening and closing of the train doors is captured by means of at least three sensor devices functioning independently of each other, which may be of the same or different construction, particularly by means of three laser scanners. 
     
     
         10 . Use of an arrangement with various spatially separated sensors for detecting the correct stopping position of a train at a platform equipped with platform doors and having various spatially separate sensors for capturing the opening and closing of the train doors of a train stopped at the platform to serve as a backup system for the controller of the opening and closing of the platform doors, which backup system then takes control of the function of opening and closing the platform doors in cases in which a communication link cannot be established, or if the communication link malfunctions between a platform door control unit and a control unit controlling the train doors. 
     
     
         11 . Arrangement according to  claim 1 , characterised in that the means for capturing the opening and closing of train doors that function independently of the communication link include at least one of the following means: a camera, a laser range finder, a laser scanner, a microphone, an ultrasound transceiver, an RFID chip reader unit. 
     
     
         12 . Method according to  claim 4 , characterised in that the opening and closing of the train doors is captured by scanning the train doors with a laser, preferably by means of a laser scanner that scans an angular or surface range. 
     
     
         13 . Method according to  claim 4 , characterised in that the opening and closing of the train doors is captured by analysing video images of the train doors. 
     
     
         14 . Method according to  claim 5 , characterised in that the opening and closing of the train doors is captured by analysing video images of the train doors.
