Self powered railway monitoring system
View Patent ↗A data gathering apparatus comprises a power generation device configured to generate power via movement of the rail. The data gathering apparatus further comprises a sensing device configured to receive power from the power generation device and to sense at least one property of the rail, wherein the property of the rail is at least partially defined by a vehicle traveling on the rail.
1. A data gathering apparatus for use with a railroad network having a rail, comprising:
a pair of rails;
a power generation device coupled to the rail and configured to generate power in response to a vehicle traveling on the pair of rails;
a sensing device configured to sense a parameter of the power generation device, wherein the parameter is at least partially defined by the vehicle traveling on the pair of rails;
communication circuitry configured to transmit the sensed parameter in accordance with a communication protocol and to receive power from the power generation device;
a processor device configured to determine a parameter of the vehicle based on the sensed parameter of the power generation device; and
a database configured to correlate the sensed parameter of the power generation device to a known parameter of the vehicle.
2. The data gathering apparatus as recited in claim 1 , wherein the processor device is located remotely with respect to the sensing device of the power generation device.
3. The data gathering apparatus as recited in claim 1 , wherein the communication protocol comprises a radio frequency (RF) protocol.
4. A railroad network, comprising
a pair of rails;
a power generation device coupled to the rail and configured to generate power in response to a vehicle traveling on the pair of rails;
a sensing device configured to sense a property of the power generation device, wherein the property is at least partially defined by the vehicle traveling on the pair of rails;
communication circuitry configured to transmit the sensed property in accordance with a communication protocol;
a processor device configured to determine a property of the vehicle based on the sensed property of the power generation device; and
a database configured to correlate the sensed property of the power generation device to a known property of the vehicle.
5. The railroad network as recited in claim 4 , wherein the processor is located remotely with respect to the sensing device of the power generation device.
6. The railroad network as recited in claim 4 , wherein the communication protocol comprises a radio frequency (RF) protocol.
