Abstract

An end-of-train device, a system, and a method for monitoring barrier gates are provided. The method includes receiving at least one image associated with a barrier gate from an imaging device mounted on a train. Further, the at least one image is analyzed to determine a current status of the barrier gate. The current status corresponds to a position associated with the barrier gate. Based on the current status of the barrier gate, an action to be performed is identified. Further, one or more instructions for performing the identified action are generated.

identify acceleration data associated with the train;
preprocess the at least one image based on the acceleration data associated with the train;
determine whether the barrier gate is present in an image of the at least one image associated with the barrier gate; and
select the image for transmission to a remote server when, based on the determination, the barrier gate is present in the image, wherein the image is configured to be analyzed to determine a current status of the barrier gate; and

a location tracking device configured to determine a location of the train in real- time,
wherein the processing unit is further configured to determine an identity of the barrier gate using the location of the train.

2. The end-of-train device of claim 1 , further comprising a first memory,

3. The end-of-train device of claim 1 , further comprising:
a communication unit configured to transmit the image and the location of the train to the remote server.

4. The end-of-train device of claim 1 , further comprising an accelerometer configured to generate the acceleration data, the accelerometer being in communication with the processing unit.

5. The end-of-train device of claim 1 , wherein the processing unit is further configured to trigger the capture of the at least one image associated with the barrier based on the determined location of the train and a location corresponding to the determined identity of the barrier gate.

6. A system for monitoring barrier gates, the system comprising:
an imaging device mounted on a train, wherein the imaging device is configured to capture images associated with an environment of the train;
