Problems solved by technology

However, known methods of monitoring train length require manual data entry by the driver in the train cab
Such manual data entry is prone to error and / or late entry
Therefore, such methods are limited in determining train integrity

Embodiment Construction

[0011] [0011] The present invention provides a system for detecting and / or verifying the integrity of a train. In particular, the integrity of the train is the assessment that there is no separation of the cars. In an exemplary embodiment, the system includes a pair of radio transmitters, each transmitter including an antenna extending above the height of the train. Thus, the radios can communicate with each other using radio ranging to determine the length of the train. In an exemplary embodiment, the integrity of the train is based on the length of the train. Thus, the present invention does not require manual data entry to determine train integrity.

[0012] [0012] Furthermore, in an exemplary embodiment, one of the radios is integrated with at least one of the brake force monitor and the means arranged to determine train motion. Thus, in an exemplary embodiment, the integrity of the train is assessed based on data received from brake force monitors and / or devices config...

Abstract

A method for determining an integrity of a train is provided. The method includes coupling at least one head-of-train device to the train. The head-of-train device includes at least one first radio. The method also includes coupling at least one end-of-train device to the train. The end-of-train device includes at least one second radio. The method also includes communicating between the first and second radios using radio-ranging to determine a length of the train, and determining the integrity of the train based on the length of the train.

Description

technical field [0001] [0001] The present invention relates to railway systems, and more particularly to methods and systems for determining train integrity. Background technique [0002] [0002] At least some known trains are continuously monitored during operation to ensure train integrity. In particular, trains are monitored to ensure that no separation occurs between every two adjacent cars. For example, in some known trains, the integrity of the train is verified by monitoring the braking force of the train. Rapid changes or sudden drops in braking force will show up as cracks on the brake line. Thus, such cracks in the brake line can indicate that separation of the carriages has occurred. However, monitoring braking force does not always provide a reliable indication of train integrity. In particular, the braking force of the train was varied during the operation of the train without cracks occurring on the brake wire. In addition, cracks may also appear on brake l...
