Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0051] Such as figure 1 As shown, the embodiment of the present invention discloses a wheel derailment early warning method, comprising the following steps:

[0052] S01. Obtain the lateral vibration acceleration of the wheel;

[0053] S02. Obtain the serpentine frequency result of the wheel according to the lateral vibra...

Abstract

The invention discloses a wheel derailment early warning method, comprising the following steps: acquiring lateral vibration acceleration of the wheel; obtaining a serpentine frequency result of the wheel according to the transverse vibration acceleration; obtaining a lateral amplitude of the wheel according to the lateral vibration acceleration; outputting the wheel derailment warning informationif the lateral amplitude is greater than or equal to the amplitude preset value and the serpentine frequency result is greater than or equal to the frequency preset value,. The wheel derailment earlywarning method provided by the invention only needs to obtain single type data, namely vibration acceleration, can accurately carry out derailment early warning, the whole process is stable and reliable, and the data acquisition equipment used is few, the cost is low, and the method is easy to be applied.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a wheel derailment early 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, which correspond to many factors causing derailment, and the specific performance of the derailment is also different, and there are many parameters or values ​​for early warning. When one or more of the early warning devices is abnormal or fails, the final early warning results will be abnormal. Therefore, the existing early warning identification methods or systems have a great risk of false positives, that is, when there is a risk of derailment, they cannot be correctly identified. The phenomenon of derailment can easily lead to train serious accidents due to abnormal derailment warning. [0003] Therefore, it is an urgent problem to be solved by those skilled in the art to ...
