Description

technical field [0001] The invention relates to the technical field of infrared shaft temperature detection, in particular to a temperature measurement error correction method, device and system. Background technique [0002] Infrared shaft temperature detection system is an important facility for detecting hot shafts of vehicles, preventing hot shafts, ensuring the safety of railway transportation, and an important guarantee for improving transportation efficiency. [0003] Infrared shaft temperature detection system is usually composed of infrared detection station, road bureau monitoring center and repeating station and other parts. The detection station includes trackside equipment and indoor equipment, and completes the automatic detection of the axle temperature, wheelbase, speed and other information of the running train through the infrared probes installed on both sides of the rail, and obtains the detection data. The monitoring center of the railway bureau receive...

Problems solved by technology

At present, when there is an error in the performance parameters of the probe, it is necessary for personnel to rush to the detection station to make corrections manually

In order to ensure the safety of personnel and the operation of trains, personnel and time scheduling must be carried out first, so that specific personnel can correct the performance parameters of the probe within a safe period of time. Existing solutions usually cannot correct temperature measurement errors in a timely manner.

[0006] Moreover, with the continuous speed-up of the current railway transportation, it is more and more inconvenient for personnel to carry out on-site maintenance operations, and because the environment where the probes are usually relatively harsh and the number is large, errors in the performance parameters of the probes occur from time to time. Some solutions are far from meeting the needs of timely correction of temperature measurement errors in practice, resulting in low accuracy of detection data obtained by the infrared shaft temperature detection system, poor system performance, and hidden dangers to railway transportation safety
