Locomotive wheel set idling and sliding detection method and system

Abstract

The invention provides a locomotive wheel set idling and sliding detection method and system. The method comprises, after initial alignment is performed, acquiring reference speed, reference acceleration and wheel speed output by a combined inertial navigation system, wherein the wheel speed is determined by speed pulse information collected by a speed sensor; according to the reference speed, the reference acceleration, the wheel speed and a preset formula, computing speed difference, acceleration difference and sliding rate; when the reference acceleration, the speed difference, the acceleration difference and the sliding rate meet preset idling judging conditions, determining that the operating state of a locomotive wheel set is an idling state; when the reference acceleration, the speed difference, the acceleration difference and the sliding rate meet preset sliding judging conditions, determining that the operating state of the locomotive wheel set is a sliding state. Therefore, the locomotive wheel set idling and sliding detection method achieves the effects of detecting whether the locomotive wheel set is idling or sliding to well ensure train safety.

Description

technical field [0001] The invention relates to the technical field of locomotive operation control, in particular to a method and system for detecting idling and sliding of locomotive wheel pairs. Background technique [0002] Since April 1, 1997, my country's railways have carried out seven large-scale speed increases, and on April 18, 2007, the EMUs with the prefix "D" have been put into operation, and since July 1, 2010 , my country has entered the era of high-speed rail, and the maximum speed of high-speed rail can reach more than 300 kilometers per hour. The use of heavy-duty freight locomotives has enabled the traction tonnage to reach more than 10,000 tons. At present, the total power of my country's "harmonious" high-power electric locomotives has reached 10MW, ranking first in the total power of locomotives in the world. [0003] However, no matter whether it is to increase the running speed of the locomotive or to continuously increase the load of the locomotive, ...

AI Technical Summary

Problems solved by technology

If the adhesion between the wheels and rails is damaged during the operation of the locomotive, the wheels of the locomotive will slide or idle, which will cause wear and tear on the wheels and rails, which will not only increase the maintenance cost of the railway operation, but even threaten the safe operation of the locomotive
