Benefits of technology

[0010] In one aspect of the invention, the system includes a map database and the position information from the independent positioning system is used to as an index to ensure that the rotation data used for the speed/position comparison between the position system and rotation data is collected in an area of straight and flat track so as to exclude errors in the rotation data caused by wheel slippage and turns.
[0011] In another aspect of the invention, the data used for the comparison betwe...

Embodiment Construction

[0018] The present invention will be discussed with reference to preferred embodiments of train control systems. Specific details, such as wheel sizes and types of positioning systems, are set forth in order to provide a thorough understanding of the present invention. The preferred embodiments and specific details discussed herein should not be understood to limit the invention.

[0019] Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 is a logical block diagram of a train control system 100 according to the present invention. The system 100 includes a control module 110, which typically, but not necessarily, includes a microprocessor. The control module 110 is connected to a revolution counter 120. The revolution counter 120 measures rotation of a locomotive wheel (not shown in FIG. 1) on a train. The revolution counter 120 may be of any type, including mechanical, magnetic, and optical. Th...

Abstract

A method and system for compensating for wheel wear uses position and/or speed information from an independent positioning system to measure some distance over which the train has traveled. Wheel rotation information is also collected over the distance. The wheel rotation information and distance and/or speed information are then use to determine the size of the train wheels. The method is performed periodically to correct for changes in wheel size over time due to wear so that the wheel rotation information can be used to determine train position and speed in the event of a positioning system failure.

Description

[0001] This application is a U.S. Divisional Application of U.S. application Ser. No. 10 / 609,377, filed Jul. 1, 2003, which is a Continuation-In-Part of application Ser. No. 10 / 157,874, filed May 31, 2002, now U.S. Pat. No. 6,701,228, issued Mar. 2, 2004. The entirety of both of the above-mentioned applications are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to railroads generally, and more particularly, to a system and method for determining wheel size to compensate of wheel wear. [0004] 2. Discussion of the Background [0005] Controlling the movement of trains in a modern environment is a complex process. Collisions with other trains must be avoided and regulations in areas such as grade crossings must be complied with. The pressure to increase the performance of rail systems, in terms of speed, reliability and safety, has led to many proposals to automate various aspects of train operation. For example,...
