Method and apparatus for the accurate linear speed measurement of trains
The calculation of the speed of a moving train is critical to being able to capture high speed resolution images of the undercarriage of a moving train using a camera in an associated application. The measurement must be extremely accurate and in real time so that an appropriately placed camera can capture images and transmit those images to a remote location.
1. A device to measure the linear speed of a train, which is comprised of:
a. a plurality of sensors;
wherein the plurality of the sensors will calculate the speed of a train;
wherein the plurality of sensors is secured to a bar;
said bar is secured to a railroad track;
wherein each individual sensor is encased in a protective casing;
b. a plurality of rare earth magnets;
wherein the plurality of rare earth magnets is positioned along the exterior of the bar;
wherein the plurality of rare earth magnets secures the bar to a rail of a rail road track;
c. a controller;
wherein the controller is located within the speed sensor casing;
wherein the controller transmits the information provided by the plurality of sensors to software;
wherein the software uses the information provided by the plurality of sensors to calculate the linear speed of the train;
d. a plurality of speed sensor stabilizers;
wherein the plurality of speed sensor stabilizers is affixed to the bar.
2. The device as described in claim 1 wherein the placement of the plurality of sensors is placed on the interior of the railroad track.
3. The device as described in claim 1 wherein the placement of the plurality of sensors is placed on the exterior of the railroad track.
4. The device as described in claim 1 wherein the speed of the train is calculated within a fraction of a mile per hour.
5. The device as described in claim 1 wherein each sensor of the plurality of sensors is an inductive sensor.
6. The device as described in claim 1 wherein a plurality of bars is affixed to both rails of the railroad track.
7. The device as described in claim 1 wherein a predetermined distance is provided between each sensor of the plurality of sensors.
8. The device as described in claim 1 wherein the plurality of sensors operates in series.
