Railroad signal aspect compliance monitoring systems and methods
First Claim
Patent Images
1. A system for remotely monitoring compliance with a railroad signal associated with a section of railroad track, comprising:
- a remote aspect compliance subsystem for monitoring compliance with an indication for the section of railroad track represented by an aspect of the railroad signal and selectively generating a corresponding compliance message, wherein the aspect is a red aspect and the remote aspect compliance monitor generates a compliance message when a train crew runs-by the red aspect at a speed exceeding a predetermined maximum speed limit, the remote aspect compliance subsystem comprising;
a signal aspect detector for determining the current aspect of the railroad signal;
a set of wheel detectors for detecting movement of a train in the section of railroad track proximate the railroad signal;
a processor for determining from the current aspect of the railroad signal and signals from the wheel detectors compliance with the indication provided by the current aspect and selectively generating a message in response; and
a communications unit for transmitting generated messages to a server; and
the server communicating with the remote aspect compliance subsystem via a network for receiving and processing compliance messages received from the remote aspect compliance unit.

Abstract
A system for remotely monitoring compliance with a railroad signal associated with a section of railroad track includes a remote aspect compliance subsystem for monitoring compliance with an indication for the section of railroad track represented by an aspect of the railroad signal. The remote aspect compliance subsystem selectively generates corresponding compliance messages, which are communicated via a network to server for display and processing.

8. A railroad signal aspect compliance monitoring system comprising:
-
a central office including a server and at least one workstation; at least one remote monitoring subsystem for monitoring compliance with an indication provided by an aspect presented by at least one railroad signal, comprising; a signal aspect detector for detecting the aspect of the railroad signal; first and second spaced apart wheel detectors for detecting movement of a train within a section of track proximate to the railroad signal; a processor for determining from the detected aspect and signals received from the wheel detectors compliance with the indication provided by the detected aspect and selectively generating a message in response, wherein the detected aspect is a red aspect and the remote aspect compliance monitor generates a compliance message when a train crew runs-by the red aspect at a speed exceeding a predetermined maximum speed limit as detected by the wheel detectors; and a wireless communications unit for transmitting generated messages wirelessly to the central office server for selective display on the workstation. - View Dependent Claims (9, 10, 11, 12, 13)
