摘要:
A method and a protection system for signaling protection of rail vehicles connected to at least one central monitoring facility through a data radio system. In order to eliminate cost-intensive and highly complicated protection technology, the vehicles convey instantaneous position data through the data radio system to the monitoring facility. A safety area is defined around each of the vehicles. The safety area depends on a vehicle speed and a measured value scatter of the positional data collection method being used. A warning area surrounds the safety area and the monitoring facility determines movement-defining data through the vehicle-specific position data, safety areas and warning areas. In order to avoid collision-related overlaps of safety zones and to counteract collision-related overlaps of warning areas, the movement-defining data are transmitted to the affected vehicles by way of the data radio system in the event of collision-relevant overlaps.

A transporting vehicle system includes a prohibited travel zone setter that sets a first prohibited travel zone where entry of a travelling vehicle is prohibited, an additional prohibited travel zone setter that sets a second prohibited travel zone upstream of the first prohibited travel zone according to rules, and a transporting vehicle controller that controls a transporting vehicle to prevent the vehicle from entering the first prohibited travel zone or the second prohibited travel zone.

A method is disclosed of detecting a railway vehicle, comprising using the time difference between receiving at first and second points a signal sent from the vehicle at a given time to produce an indication of the location of the vehicle.
摘要:
An anti-collision safety control for vehicles travelling on tracks; the control comprises two safety loops per vehicle, linked to two common loops in a central control station. Each vehicle loop comprises control circuits for determining the distance to the next preceding vehicle, for determining a safe stopping distance for the vehicle, and for stopping the vehicle if the distance to the preceding vehicle becomes smaller than the safe stopping distance or if there is a failure of a safety circuit. The distance control circuit comprises a detector for detecting reference points provided along the track, a counter for calculating the distance of a vehicle from a given zero location, and a delay circuit for converting this distance into a position signal timed to a synchronization pulse received by all vehicles. Position signals from all vehicles are transmitted to the central control and back to the vehicles; the distance to an immediately preceding vehicle is determined by comparing the position pulses.
