System, Method, and Apparatus for Certifying a Brake Pressure Calibration for an End-of-Train Device

摘要

A system, method, and apparatus for certifying an end-of-train device pressure calibration is provided. The system includes an end-of-train device including a brake pipe interface adapted to be removably connected to a brake pipe system of a train and to receive air having a pressure from the brake pipe system, and a pressure sensing device configured to measure the air pressure received in the brake pipe interface to obtain a measured pressure. The system also includes a pressure calibration device adapted to be removably connected to the brake pipe interface when the end-of-train device is removed from the train, the pressure calibration device configured to output air at a regulated pressure to the brake pipe interface, and at least one controller programmed or configured to determine a calibration certification result based at least partially on a difference between the measured pressure and the regulated pressure.

1. A system for certifying an end-of-train device pressure calibration, comprising:
(a) an end-of-train device comprising:
(i) a brake pipe interface adapted to be removably connected to a brake pipe system of a train and to receive air having a pressure from the brake pipe system; and(ii) a pressure sensing device configured to measure the air pressure received in the brake pipe interface to obtain a measured pressure; (b) a pressure calibration device adapted to be removably connected to the brake pipe interface when the end-of-train device is removed from the train, the pressure calibration device configured to output air at a regulated pressure to the brake pipe interface; and (c) at least one controller programmed or configured to determine a calibration certification result based at least partially on a difference between the measured pressure and the regulated pressure.
