Embodiment Construction
[0028] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.
[0029]The existing TPDS realizes the alarm for tread damage according to the detected impact equivalent of the train, but when the TPDS alarms, the tread damage is often obvious. However, the existing alarm methods for tread damage do not consider the development process and trend of tread damage, do not use historical monitoring information, and cannot achieve early warning of faults, and TPDS cannot quantitatively give tread damage. parameter indicator. The embodiment of the present invention utilizes the monitoring data of the existing TPDS, performs weighted sliding window accumulation and exponentially weighted smoothing processing on the historical impact equivale...

The invention relates to the technical field of train maintenance, discloses a treatment method, device and storage medium for train wheel tread damage, and solves the problem that early warning of tread damage cannot be realized in the prior art. The method includes: obtaining the monitoring data of the vehicle running quality trackside dynamic monitoring system TPDS of the selected wheels, the monitoring data including historical monitoring data and current monitoring data; sequentially performing sliding window iteration and smoothing processing on the monitoring data to obtain The current tread damage prediction value corresponding to the current monitoring data; judging whether the current tread damage prediction value is greater than or equal to the early warning threshold; if the current tread damage prediction value is greater than or equal to the early warning threshold, prompting the The selected wheel has a tread damage failure. The embodiment of the present invention is applicable to the tread damage treatment process of the wheel.
Description
technical field [0001] The invention relates to the technical field of train maintenance, and in particular, to a method, device and storage medium for treating damage to the tread of a train wheel. Background technique [0002] With the operation of high-speed and heavy-duty railway trains, wheel tread failure has become an important form of failure found during the operation of the vehicle, and the monitoring of tread damage has become more and more important. The existing main methods of wheel tread damage monitoring include manual identification of train inspection and TPDS (Truck Performance Detection System, trackside dynamic monitoring system for vehicle running quality) alarm. The rate is high, and manual inspection can only find more obvious tread failures. TPDS is to obtain the impact equivalent by monitoring the impact force between the wheel and rail, and comprehensively considering factors such as wheel weight and speed, so as to make a scientific and reasonabl...
