Wide-temperature-range intelligent iron shoe and anti-slip state judgment method thereof

Abstract

The invention discloses a wide-temperature-range intelligent iron shoe. The iron shoe is composed of a traditional iron shoe and embedded hardware installed in the traditional iron shoe, and the embedded hardware comprises a central processing unit, a temperature sensor, a GPS positioning module, an acceleration sensor and an ultrasonic ranging unit. The central processing unit is used for signalacquisition of the temperature sensor, the acceleration sensor and the ultrasonic ranging unit, data acquisition and data processing of the GPS positioning module, distance operation and intelligent iron shoe state judgment. The wide-temperature-range intelligent iron shoe is suitable for various railway stations. On the whole, whether the vehicle is in an anti-slip state or not can be judged through multi-sensor fusion; multi-angle judgment is performed on the anti-slip state of the intelligent iron shoe by adopting a mode based on position judgment, intelligent iron shoe motion state and posture calculation and ultrasonic ranging analysis; and the situation that judgment errors occur in a complex working environment in a single judgment mode is effectively avoided, and the accuracy and reliability of intelligent iron shoe anti-slip state judgment are greatly improved.

Description

technical field [0001] The invention relates to the field of railway safety, and is especially suitable for monitoring the anti-slip state of intelligent iron shoes under the condition of wide temperature change, and in particular relates to an intelligent iron shoe with a wide temperature range and a method for judging the anti-slip state thereof. Background technique [0002] With the rapid development of railway transportation, the number of railway lines is increasing and the coverage area is expanding. The application of smart iron shoes is also becoming more and more extensive. Smart iron shoes have become an important equipment to protect the safety of personnel and vehicles in railway stations. [0003] The traditional smart iron shoes have the following problems: after the smart iron shoes are deployed, it is impossible to monitor the situation that the smart iron shoes are not installed properly due to the accidental sliding of the train, resulting in certain safety...

AI Technical Summary

Problems solved by technology

[0003] The traditional smart iron shoes have the following problems: after the smart iron shoes are deployed, it is impossible to monitor the situation that the smart iron shoes are not installed properly due to the accidental sliding of the train, resulting in certain safety hazards; The influence of factors is too large to make an accurate judgment on the working status of the smart iron shoes; the movement of the smart iron shoes left and right on the track will cause a large jump in the measured distance between the train wheel and the smart iron shoes, causing smart Unnecessary changes in the status judgment of iron shoes; smart iron shoes often have problems of poor working condition and high misjudgment rate in low temperature environments, resulting in the measured distance between the train wheel and the smart iron shoes being much larger than the actual value. Causes misjudgment of the working status of smart iron shoes; the judgment method of the anti-slip state of smart iron shoes is single, which is easily affected by the external environment, which is not conducive to accurate judgment of the working status of smart iron shoes
