Problems solved by technology

[0004] At present, the processing methods for temperature detection data are mostly focused on the research of conventional general filtering algorithms such as data fitting, FIR filtering, and wavelet filtering, while the on-site environment of trains working on shaft temperature is complex, with many interference factors and scattered frequency characteristics. It is difficult to achieve the effect simply by one or several general filtering algorithms

Abstract

The invention discloses a pre-alarm method and a device for the axle temperature of a train. The method comprises the steps that collecting and caching axle temperature data in real time; analyzing the axle temperature data, and extracting characteristic parameters of axle temperature changes; judging whether abnormal interference characteristics exist in the axle temperature data or not accordingto the characteristic parameters of the axle temperature change; if there are abnormal interference characteristics in the axle temperature data, performing no axle temperature pre-alarm monitoring;otherwise, carrying out axle temperature pre-alarm monitoring on the axle temperature data. According to the invention, the accuracy of fault detection can be improved, and misinformation is reduced.And the method consumes few computing resources, is easy to implement in an embedded mode, and is high in real-time performance.

Description

Technical field [0001] The invention belongs to the technical field of rail transit, and particularly relates to a pre-alarm method and device for train axle temperature. Background technique [0002] Trains are one of the main means of transportation in modern times. They play a great role in the transportation of passengers and goods. Their safety issues have always been paid close attention to by people from all walks of life. In order to prevent the internal failure of the wheelset bearings, causing accidents such as burning axles, cutting axles and even throwing off the car, the train has installed bearing temperature sensors on the side of each axle box body to monitor the state of axle box bearings, and transmit this temperature data For the train network control system, when an abnormal rise in bearing temperature is found, the train network control system will display corresponding information through the driver’s cab display screen to remind the driver to take decelerat...
