Cab signal quality detecting and reporting system and method

摘要

A system and method for railroad cab signal quality detection and reporting for use in connection with a railroad cab signaling system in which a status signal is carried on a railroad rail. The status signal has a cab signal parameter that is indicative of a status of a zone of track. A signal detector detects the status signal transmitted via the railroad rail. A signal measurement subsystem associated with the signal detector measures the cab signal parameter. A quality analysis subsystem analyzes the measured cab signal parameter and determines a measure of quality of the cab signal parameter. The system may include equipment that is mounted on a rail vehicle, such as a locomotive, or mounted along a block of track, or on portable equipment. The system may also include a cab signal quality collection and reporting system. The method includes detecting the cab status signal and measuring the cab signal parameter from the detected status signal. The measure of quality of the measured cab signal parameter is determined and is reported.
