The invention relates to a train axle temperature detection method and device. The method comprises the following steps: receiving respectively measured train axle temperatures from a digital temperature measurement unit and a simulation temperature measurement unit, and acquiring a train state if a first temperature difference between the train axle temperatures is greater than a first threshold value and the first temperature difference lasts for a target time interval; under the condition that the train state is a running state, comparing the target suspicious degree values of the digital temperature measurement unit and the simulation temperature measurement unit, and taking the train axle temperature measured by the temperature measurement unit with a relatively small target suspicious degree value as an admissible value; under the condition that the train state is a standing cooling state, acquiring a second temperature difference between the measured train axle temperature and an environment temperature; under the condition that the second temperature differences corresponding to the digital temperature measuring unit and the analog temperature measuring unit are not greater than a second threshold value, acquiring the train axle temperature measured by the digital temperature measuring unit; and under the condition that the second temperature difference corresponding to the digital temperature measurement unit or the analog temperature measurement unit is not greater than the second threshold value, acquiring the train axle temperature corresponding to the second temperature difference which is not greater than the second threshold value.
本发明涉及列车轴温检测方法及装置,通过从数字测温单元及模拟测温单元接收各自测得的列车轴温,若列车轴温之间的第一温差大于第一阈值、且第一温差持续目标时间区间,则获取列车状态。在列车状态为运行状态的情况下,比较数字测温单元及模拟测温单元各自的目标可疑度值,采信目标可疑度值相对较小的测温单元所测得的列车轴温。在列车状态为静置冷却状态的情况下,获取所测得的列车轴温与环境温度的第二温差。在数字测温单元及模拟测温单元各自对应的第二温差均不大于第二阈值的情况下,则采信数字测温单元测得的列车轴温。在数字测温单元或模拟测温单元对应的第二温差不大于第二阈值的情况下,则采信不大于第二阈值的第二温差所对应的列车轴温。
