Abstract

A system (200) for monitoring a railroad grade crossing (100, 250) includes an illumination device (220, 230) for illuminating a section of a railroad grade crossing (100, 250), and a control device (240) in communication with the illumination device (220, 230). The illumination device (220, 230) is configured to obtain data of the section of the railroad grade crossing (100, 250) while illuminating the section, and the control device (240) is configured to receive and evaluate the data. Further, a method (600) for monitoring a railroad grade crossing (100, 250) is provided.

First claim

The invention claimed is:

1. A system for monitoring a railroad grade crossing comprising:
an illumination device comprising a lidar sensor for illuminating a section of a railroad grade crossing, and
a control device in communication with the illumination device,
wherein the illumination device is configured to obtain data of the section of the railroad grade crossing while illuminating the section, and
wherein the control device is configured to receive and evaluate the data,
wherein the control device is configured to detect, track and classify an object within the section based on the data of the illumination device,
wherein a classification comprises determining whether the object is any one of a vehicle, a cyclist, and a pedestrian,
wherein the control device is configured to trigger activation of an entrance gate and/or exit gate to a raised position when the classified object is a vehicle, and
wherein the control device is further configured to detect a direction of a train and measure a speed of the train based on data obtained by the illumination device when the train travels through the railroad grade crossing.

2. The system of claim 1 , wherein the section comprising a track crossing area.

3. The system of claim 1 , wherein the control device is configured to communicate with components activating crossing warning devices.

4. The system of claim 1 , wherein the control device is configured to trigger activation of a crossing warning device of the railroad grade crossing when an object is detected within the section.

5. The system of claim 1 , wherein the lidar sensor comprises at least one laser beam configured to rotate around 360 degrees multiple times per second.

6. The system of claim 1 , wherein the illumination device is arranged on an existing crossing infrastructure of the railroad grade crossing.

7. The system of claim 1 , wherein the control device is located in a crossing bungalow.

8. The system of claim 1 , wherein the illumination device and the control device communicate via a wired connection, the wired connection comprising Ethernet connection.

9. The system of claim 1 , wherein the illumination device and the control device communicate via a wireless connection.

10. The system of claim 1 , comprising a plurality of illumination devices positioned to scan areas of the railroad grade crossing including a track crossing area, areas of a road and a railroad track around the track crossing area.

11. The system of claim 1 , wherein the control device comprises an industrial PC.

12. The system of claim 1 , wherein the control device comprises a user interface or is coupled to a client HMI.

13. A method for monitoring a railroad grade crossing comprising:
obtaining data of a section of a railroad grade crossing while illuminating the section by at least one illumination device, the at least one illumination device comprising a lidar sensor;
receiving the data by a control device in communication with the at least one illumination device;
evaluating the data by the control device, wherein the control device is configured to communicate with components activating crossing warning devices,
wherein the evaluating comprises detecting, tracking, and classifying an object within the section based on the data of the at least one illumination device,
wherein a classification comprises determining whether the object is any one of a vehicle, a cyclist, and a pedestrian, and
wherein the crossing warning device comprises crossing gates, and wherein a crossing entrance gate and/or crossing exit gate is raised, and further comprising
detecting a direction of a train and measuring a speed of the train based on data obtained by the illumination device when the train travels through the railroad grade crossing.

14. The method of claim 13 , further comprising:
activating of a crossing warning device when an object is detected within the section.
