Automatic arming of a head-of-train device to an end-of-train device
A system and method for enabling automatic arming between an End-of-Train device and a Head-of-Train device on a train is provided. The system includes at least one sensing unit configured to detect a physical connection status of the End-of-Train device. The End-of-Train device is configured to transmit an arming request to the Head-of-Train device based on the physical connection status, wherein the arming request includes at least one of an identifier and a geospatial location associated with the End-of-Train device. The Head-of-Train device is configured to receive the arming request from the End-of-Train device. The Head-of-Train device is further configured to arm the Head-of-Train device to the End-of-Train device upon verification of the arming request, wherein arming comprises establishing a communication channel between the Head-of-Train device and the End-of-Train device.
1 . A system for enabling automatic arming between an End-of-Train device and a Head-of-Train device on a train, the system comprising:
at least one sensing unit configured to:
detect a physical connection status of the End-of-Train device, wherein the physical connection status indicates that the End-of-Train device is physically coupled to the train, wherein the at least one sensing unit comprises a pressure sensor and a camera, and the physical connection status is detected based on outputs from the pressure sensor and the camera in conjunction with a voltage output of a generator of the End-of-Train device;
wherein the End-of-Train device is configured to:
transmit an arming request to the Head-of-Train device based on the physical connection status; and
wherein the Head-of-Train device is configured to:
receive the arming request from the End-of-Train device; and
arm the Head-of-Train device to the End-of-Train device upon verification of the arming request, wherein arming comprises establishing a communication channel between the Head-of-Train device and the End-of-Train device.
2 . The system as claimed in claim 1 , wherein the at least one sensing unit further comprises an accelerometer used to trigger an operation of the camera.
3 . The system as claimed in claim 1 , wherein the arming request comprises at least one of an identifier and a geospatial location associated with the End-of-Train device.
4 . The system as claimed in claim 3 , wherein the Head-of-Train device is further configured to:
verify the arming request locally based on at least one of the geospatial location of the End-of-Train device, a length of the train, an output of the at least one sensing unit and a Received Signal Strength Indicator associated with the arming request.
5 . The system as claimed in claim 1 , wherein the Head-of-Train device is communicatively coupled to a remote server, and wherein the Head-of-Train device is configured to:
generate a verification request based on the arming request; and
transmit the verification request to the remote server.
6 . The system as claimed in claim 5 , wherein the remote server is configured to:
receive the verification request comprising the arming request from the Head-of-Train device;
verify the arming request based on a predefined logic upon receiving the verification request; and
transmit a response comprising an outcome of the verification to the Head-of-Train device.
7 . A method for enabling automatic arming between an End-of-Train device and a Head-of-Train device, the method comprising:
receiving, by the Head-of-Train device, an arming request from the End-of-Train device, wherein the arming request is generated by the End-of-Train device based on a physical connection status of the End-of-Train device detected using at least one sensing unit, wherein the physical connection status indicates that the End-of-Train device is physically coupled to the train, wherein the at least one sensing unit comprises a pressure sensor and a camera, and the physical connection status is detected based on outputs from the pressure sensor and the camera in conjunction with a voltage output of a generator of the End-of-Train device; and
arming the Head-of-Train device to the End-of-Train upon verification of the arming request, wherein arming comprises establishing a communication channel between the Head-of-Train device and the End-of-Train device.
8 . The method as claimed in claim 7 , wherein the arming request comprises at least one of an identifier and a geospatial location associated with the End-of-Train device.
9 . The method as claimed in claim 8 , further comprising:
verifying the arming request locally, by the Head-of-Train device, based on at least one of the geospatial location of the End-of-Train device, a length of the train and a Received Signal Strength Indicator associated with the arming request.
10 . The method as claimed in claim 7 , further comprising:
generating a verification request based on the arming request; and
transmitting the verification request to a remote server.
11 . The method as claimed in claim 10 , wherein the remote server verifies the arming request based on a predefined logic upon receiving the verification request.
12 . The method as claimed in claim 11 , further comprising:
receiving, by the Head-of-Train device, a response comprising an outcome of the verification.
