The invention discloses a train axle temperature abnormality detection method and a device. The method includes: acquiring current data of train axle temperature in real time; comparing the current data with a temperature distribution model constructed in advance, wherein the temperature distribution model is a model which realizes modeling analysis of historical axle temperature data under normal conditions to extract corresponding data features so as to determine a train axle temperature abnormality judgment threshold; generating result information for determining that the current axle temperature is abnormal when current data exceed the train axle temperature abnormality judgment threshold. The historical axle temperature data are analyzed comprehensively, data features are mined deeply, daily axle temperature distribution conditions and abnormal conditions are analyzed to deduce axle temperature abnormality possibility, axle temperature abnormality recognition rules are found out, the judgment threshold for judging whether the axle temperature is abnormal or not is set on the basis of data analysis results and expert knowledge, axle temperature abnormality detection accuracy is improved, and safety operation of a train is guaranteed. In addition, the invention further provides a train adopting the train axle temperature abnormality detection method and the device.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a method, a device and a train for detecting abnormal train axle temperature. Background technique [0002] The train is one of the main means of transportation in modern times, and it has played a great role in the transportation of passengers and goods. Its safety has always been the focus of attention of people from all walks of life. In order to prevent internal faults of the wheel set bearings from causing accidents such as burning shafts, cutting shafts, and even dumping trains, a bearing temperature sensor is installed on the side of each axle box to monitor the status of the axle box bearings, and the temperature data Pass it to the train network control system. When abnormal axle temperature is found, the train network control system will display the corresponding information through the driver's cab display screen to remind the driver to take deceleration and speed...
