Abstract

The invention discloses a wheel derailment early-warning method. The wheel derailment early-warning method comprises the following steps of obtaining a vibration acceleration of a wheel; obtaining impact data of the wheel; obtaining vibration amplitude data of the wheel according to the vibration acceleration; and if the vibration amplitude data is larger than or equal to a first vibration amplitude preset value and the impact data is larger than or equal to a first impact preset value, outputting wheel derailment early-warning information. According to the wheel derailment early-warning method, early warning can be accurately made for derailment only by obtaining the vibration acceleration and the impact data; the whole process is stable and reliable; the number of the used data acquisition devices is small; the cost is low; and the application is easy.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a wheel derailment warning method, device and system. Background technique [0002] The train derailment accident is one of the most serious accidents. There are many types of train derailment, and the reasons for the train derailment are quite complicated. At present, there is no one that can meet the requirements of online, real-time, accurate, non-missing, Effective means of no false positives. If multiple signals are collected in order to meet the various signal values ​​and judged by the set threshold, the detection and data analysis are very complicated. When a signal is wrong, it will lead to missed or false positives, and sometimes only one If the signal value exceeds the standard, it is impossible to judge whether there is a risk of derailment. If you set too many signal values ​​and need to meet the conditions at the same time to trigger an early warnin...
