System and method for optical locomotive decoupling detection

Abstract

An apparatus and method for indicating whether a coupler of a locomotive is in a coupled or uncoupled state is provided. The apparatus comprising: an optical sensor positioned on a portion of the coupler, wherein the sensor provides a real-time signal indicative of either a coupled or an uncoupled state of a coupler, wherein the signal is transmitted wirelessly by a transmitter in operable communication with the sensor. The method comprising: providing a signal indicative of the presence or proximity of a second coupler to the first coupler, the signal being provided by an optical sensor configured to provide the signal as the state of the coupler has changed; transmitting the signal wirelessly to a controller; processing the signal with a control algorithm resident upon the controller; and providing visually perceivable indication of the position of the coupler.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 11 / 317,067 entitled “SYSTEM AND METHOD FOR DETERMINING WHETHER A LOCOMOTIVE OR RAIL ENGINE IS COUPLED TO A RAIL CAR OR OTHER ENGINE”, filed on 23 Dec. 2005, the entirety of which is incorporated by reference herein.TECHNICAL FIELD[0002]The systems and techniques described herein relate generally to rail yards, and more particularly to methods and apparatus for determining whether a train engine is coupled to a rail car.BACKGROUND[0003]Rail yards are the hubs of railroad transportation systems. Therefore, rail yards perform many services, for example, freight origination, interchange and termination, locomotive storage and maintenance, assembly and inspection of new trains, servicing of trains running through the facility, inspection and maintenance of railcars, and railcar storage. The various services in a rail yard compete for resources such as per...

Problems solved by technology

The various services in a rail yard compete for resources such as personnel, equipment, and space in various facilities so that managing the entire rail yard efficiently is a complex operation.

For example, automated equipment identification (AEI) readers and AEI computers determine the location of rolling stock at points in the sequence of operations, but in general, this information is limited to data indicating rolling stock whereabouts at particular times only, such as the moment at which the rolling stock arrived, the moment at which the rolling stock passes the AEI reader, and the moment at which the rolling stock departs.

However, an operator-monitored system can be inefficient in that it does not result in real time monitoring of the train engine's status as such communication, if present, may be exchanged well after the coupling or uncoupling event has occurred.
