Abstract

The invention relates to a monitoring device ( 1 ) for a buffer stop ( 2 ) on a track system ( 3 ), having at least one acceleration sensor ( 100 a, 100 b ) and a vibration measuring device ( 10 ). Improved monitoring can be achieved in that the vibration measuring device ( 10 ) is designed to calculate a displacement path of the buffer stop ( 2 ) from the signals detected by the acceleration sensor ( 100 a, 100 b ).

Claims (24)

1 . A monitoring device for a buffer stop on a track system, the monitoring device comprising:

at least one acceleration sensor configured and arranged to detect an acceleration of the monitoring device, and;

a vibration measuring device is configured and arranged to calculate a displacement path of the buffer stop from the signals detected by the acceleration sensor.

2 . The monitoring device according to claim 1 , wherein the vibration measuring device is configured and arranged to integrate the signal of the acceleration sensor twice.

3 . The monitoring device of claim 1 , wherein the at least one acceleration sensor includes a second acceleration sensor.

4 . The monitoring device of claim 1 , further including a distance measuring device configured and arranged for determining the distance of an arriving rail vehicle from the buffer stop and for determining the speed profile of the rail vehicle.

5 . The monitoring device of claim 1 , further including a camera configured and arranged for recording collision events.

6 . The monitoring device of claim 1 , further including a recording device configured and arranged for storing the signals detected by the acceleration sensor.

7 . The monitoring device of claim 1 , further including a transmission device configured and arranged for transmitting the signals detected data by the acceleration sensor to a control station.

8 . The buffer stop comprising:

a frame,

at least one impact plate attached to the frame, the at least one impact plate having an anchoring device, and

a monitoring device according to claim 1 is attached to the buffer stop.

9 . The buffer stop according to claim 8 , wherein the monitoring device is arranged at least partially on the frame of the buffer stop.

10 . The buffer stop according to claim 9 , wherein the at least one acceleration sensor includes a second acceleration sensor mounted on the buffer stop.

11 . A method for monitoring a buffer stop including the following steps:

detecting and evaluating a signal of an acceleration sensor, and

a monitoring device according to claim 1 is at least partially attached to the buffer stop and operated.

12 . The method according to claim 11 , wherein the signal of the acceleration sensor is integrated twice.

13 . The method according to claim 12 , wherein the integration of the acceleration sensor signal begins when the signal from the acceleration sensor exceeds a first threshold value and ends when the signal from the acceleration sensor falls below a second threshold value for a predetermined period of time.

14 . The method according to claim 11 , further including the step of detecting a signal of a second acceleration.

15 . The method according to claim 11 , further including the steps of determining distance of an arriving rail vehicle from the buffer stop and a velocity curve of the arriving rail vehicle.

16 . The monitoring device of claim 2 , wherein the integration of the acceleration sensor signal starts when the signal of the acceleration sensor exceeds a first threshold value and ends when the signal of the acceleration sensor falls below a second threshold value for a predetermined period of time.

17 . The monitoring device of claim 5 , wherein the camera is coupled to the acceleration sensor.
