Apparatus and method for estimating railway vehicle masses

摘要

Disclosed is an apparatus and method for estimating railway vehicle masses, the method comprising checking if a train has entered an initial acceleration section and a straight section, receiving a speed of the train, each acceleration of the plurality of railway vehicles and each traction of the plurality of railway vehicles, dynamically modeling the train, and estimating masses of the plurality of railway vehicles and rail gradient.

1. An apparatus for estimating each railway vehicle mass and rail gradient of a plurality of railway vehicles in a train including the plurality of railway vehicles, the apparatus comprising:
a modeling unit configured to dynamically model the train by:
receiving, via a speed sensor, a speed of the train;receiving, via acceleration sensors, an acceleration of each of the plurality of railway vehicles;receiving, via a traction device, a traction of the plurality of railway vehicles, wherein the speed, the acceleration, and the traction are received when the train is at an initial acceleration section of a railway and when the train is at a straight section of the railway; and an estimation unit configured to estimate masses of the plurality of railway vehicles and railway gradient using a dynamic modeling modeled by the modeling unit; and wherein the modeling unit models in such a manner that a sum of multiplication of the masses of the plurality of railway vehicles by acceleration of each railway vehicle is a value in which traction of each railway vehicle is deducted by a gradient resistance of each railway vehicle, a running resistance of each railway vehicle, and curving resistance of each railway vehicle.
