Wheel diameter correction method, device, apparatus, and readable storage medium

Abstract

The invention discloses a wheel diameter correction method, which comprises the following steps: collecting speed signals of a plurality of wheel pairs in a preset period; Judging whether the speed signal of each wheel pair exceeds a preset threshold value; If not, the collected maximum speed signal is determined as the target signal, the ratio of the collected speed signal of each wheel pair to the target signal is determined as the correction coefficient of each wheel pair, and the speed correction value of each wheel pair is calculated according to the correction coefficient of each wheel pair. According to the collected speed signals of each wheel pair, The correction coefficients of each wheel pair are determined, and the speed correction values of each wheel pair are calculated according to the correction coefficients, so that the speeds of each wheel pair can be under the same datum condition, the accurate judgement basis for the anti-skid system is provided, the performance andreliability of the anti-skid system are improved, and the running safety of the locomotive is ensured. Accordingly, the invention discloses a wheel diameter correction device, a device and a readablestorage medium, which also have the technical effects mentioned above.

Description

technical field [0001] The invention relates to the technical field of locomotive anti-skid control, and more specifically, to a wheel diameter correction method, device, equipment and readable storage medium. Background technique [0002] With the localization of EMUs and the improvement of operating speed, higher requirements are put forward for railway safety. Among them, brake anti-skid control technology is an important guarantee for railway transportation safety. [0003] The criterion of the anti-skid system is generally the speed difference or deceleration, and in order to obtain the speed difference and deceleration, it is necessary to collect the wheel set speed when the locomotive is actually running. In actual use, the diameter of the locomotive wheel set will gradually decrease after natural wear or turning, so that the collected wheel set speed cannot be under the same reference condition. For example, when the diameter of the naturally worn wheel set becomes...

Problems solved by technology

[0004] At the same time, due to the different wear degree of each wheel set, its diameter is also different, so that the speed of different wheel sets under the same bogie is different.

If the speed difference is calculated by the collected actual speed of each wheel set to judge the performance of the anti-skid system, then since the speeds of each wheel set are not under the same benchmark, there will be errors in the judgment basis, which will lead to the performance and reliability of the anti-skid system Poor, may even lead to locomotive accidents, unable to guarantee the safety of locomotive transportation
