Device and method for rail-side monitoring of the position of stabled rail-based vehicle
View Patent ↗A device for infrastructure-side monitoring of a position of a stabled rail-based vehicle includes a detector for infrastructure-side detection of a change of location of the stabled vehicle and a communications entity or device configured to communicate the detected change in location over a communications network to a user of the communications network. A corresponding method, a corresponding system, a method for operating the system and a computer program product are also provided.
1. A device for infrastructure-side monitoring of a position of a stabled rail-based vehicle, the device comprising:
a detector for infrastructure-side detection of a change in location of the stabled rail-based vehicle; and
a communication entity configured to communicate the detected change in location over a communication network to a user of the communication network;
said detector and said communication entity located externally from the vehicle: and
said detector and said communication entity disposed at a location separated from the vehicle.
2. The device according to claim 1 , wherein:
said detector has a sensor entity for registering the vehicle and a sensor control unit for controlling said sensor entity in order to register the vehicle multiple times in temporal succession; and
said detector has a processing entity configured to determine the change in location based on sensor images corresponding to the vehicle having been registered multiple times.
3. The device according to claim 2 , wherein said sensor entity has at least one sensor selected from the following group of sensors: radar sensor, ultrasound sensor, infrared sensor and optical image sensor.
4. The device according to claim 1 , which further comprises:
a detector control unit for controlling said detector;
said communication entity being configured to receive a detector control command over the communication network and forward it to said detector control unit, to permit said detector control unit to control said detector based on the received detector command.
5. The device according to claim 1 , wherein said communication entity is configured to automatically communicate the detected change in location to the user over the communication network.
6. The device according to claim 1 , wherein said communication entity is configured to communicate the detected change in location to the user over the communication network in response to a corresponding enquiry from the user.
7. The device according to claim 1 , wherein said detector includes a sensor configured for emitting a signal towards the vehicle and configured for receiving the signal after being reflected from the vehicle.
8. The device according to claim 7 , wherein said sensor is a radar sensor.
