Signal box controlled crew warning system
A signal-controlled crew warning system for warning people of approaching rail vehicles on an operational track located in a warning sector of a work track. The warning system includes a track-building machine for working on the work track, a positioning system for determining the position of the track-building machine, a computer-aided monitoring system for generating warning information, warning measures for generating acoustic or optical or haptic warning signals, and a radio system for wireless data transfer. The computer-aided monitoring system is configured to set boundaries of the warning sector on a basis of the current position of the track-building machine and to automatically generate warning information for the warning sector. The track-building machine has a central control unit for processing the warning information, which control unit is coupled to the computer-aided monitoring system via the radio system. The warning sector thus moves along with the track-building machine as it travels.

10 . The signal box-controlled crew warning system according to claim 1 , wherein said central controller has an European Rail Research Institute (ERRI) interface.
11 . The signal box-controlled crew warning system according to claim 1 , wherein said track maintenance machine has a global navigation satellite system (GNSS) receiving device and said GNSS receiving device is coupled to said central controller.
12 . A method for using the crew warning system according to claim 1 , which further comprises:
carrying out track work on the working track by means of the track maintenance machine,
generating the warning information by means of the computer-aided monitoring system when a rail vehicle is approaching on the operating track, wherein before the warning information is generated by means of the computer-aided monitoring system, the boundaries of the warning sector are defined on the basis of the current position of the track maintenance machine such that the warning sector moves automatically with the track maintenance machine travelling along the working track; and
transmitting the warning information to the central controller of the track maintenance machine via the radio system in an automated manner as soon as another rail vehicle enters or approaches the automatically moving warning sector, and in that the warning means are activated by means of the central controller.
13 . The method according to claim 12 , which further comprises deriving position data of the track maintenance machine and position data of approaching rail vehicles from information of a train control system.
