The invention relates to the field of temperature monitoring, in particular to a vehicle bearing temperature online monitoring system. Obtaining an initial bearing operation data set through a temperature sensor; the method comprises the following steps: acquiring an initial bearing operation data set of a plurality of diagonal train wheels and parallel train wheels, and acquiring time domain features and frequency domain features in the initial bearing operation data set by using IpDFT difference discrete Fourier transform to obtain a feature bearing operation data set; the method comprises the following steps: establishing a TMS-CNN vehicle bearing operation identification model, optimizing the TMS-CNN vehicle bearing operation identification model, judging whether the operation temperature of the train wheel bearing reaches a preset bearing temperature or not based on the real-time operation state of the vehicle bearing, and monitoring the temperature of the train wheel bearing higher than the preset bearing temperature. And the bearing operation life of the train wheel bearing at the operation temperature is judged, and an emergency braking instruction is generated. The bearing temperature can be monitored in real time, abnormal conditions can be found in time, and train operation safety is improved.
