Abstract

The cars of a passenger transport means are provided with a sensor (3) which scans the state of the locking mechanism and with a transponder antenna (5) which is fitted to the outside of the car (1), and the stations (6) contain transmission antennas (7) which poll signals from the transponder antenna in contactless fashion.

Claims

1. Locking monitoring system for doors on passenger transport means, comprising a device, arranged at a station, for sensing the locking state of the doors, and comprising a device, mounted on the transport means (1), for transmitting the locking state to the sensing device, characterized in that the device for transmitting the locking state comprises a sensor (3), which scans the state of the locking mechanism and which is connected to a transponder antenna (5) mounted on the outside of the cabin, which transponder antenna does not require any voltage source, and in that sending antennas (7), which contactlessly poll signals from the transponder antenna, are arranged in the stations (6).
