Abstract

The invention provides a temperature compensation method and a temperature compensation device. The method comprises the steps of acquiring the temperature of a bogie of a rail train; judging whether temperature compensation for the bogie of the rail train is needed; if yes, controlling a digital potentiometer to perform temperature compensation on the bogie of the rail train. The method and the device solve the technical problem of low efficiency of manual adjustment of temperature compensation in the prior art and increase the efficiency of temperature compensation.

Description

technical field [0001] The invention relates to the field of temperature detection, in particular to a temperature compensation method and a temperature compensation device. Background technique [0002] In the actual design, there are a large number of temperature sensors on the bogie of the EMU, and there are 36 temperature sensors on the bogie of each EMU. The pre-alarm temperature thresholds of each temperature sensor are inconsistent, and the control mode is complicated, making the test operation difficult. In addition, in related technologies, during the EMU debugging process, a manually adjustable potentiometer is used for temperature compensation, which has a large number of channels, high difficulty, and low efficiency, which seriously affects the EMU debugging cycle. [0003] For the problem of low efficiency of manual adjustment of temperature compensation in the above-mentioned related technologies, no effective solution has been proposed yet.
