An intelligent iron shoe slipping alarm system

Abstract

The invention discloses an intelligent iron shoe slipping alarm system. The system includes multiple pairs of intelligent iron shoes, a router, a coordinator and a monitoring upper computer; the intelligent iron shoes include a switch module, a ZigBee communication module, a power statistics module, A distance measurement module, an acceleration measurement module and a central control module; the distance measurement module detects the distance from the intelligent iron shoe to the train wheel, and the acceleration measurement module collects acceleration data of the intelligent iron shoe; the central control module receives the information sent by the distance measurement module The distance data and acceleration data sent by the acceleration measurement module are then used to calculate the inclination angle and vibration intensity of the smart iron shoe itself based on the acceleration data. The invention judges whether the distance is in place based on the distance from the smart iron shoe to the train wheel, judges whether the posture is normal based on the inclination of the smart iron shoe itself, and judges whether slippage or other business conditions occur by calculating the standard deviation of the acceleration mode and comparing the vibration intensity.

Description

technical field [0001] The invention relates to the field of railway train slip prevention, in particular to an intelligent iron shoe slipping alarm system and a detection method thereof. Background technique [0002] Smart iron shoes are one of the anti-skid and slip-proof tools for railway shunting operations. Especially in my country's railways, smart iron shoes are the inevitable choice for the anti-slip method of getting off trains. The work of preventing the train from slipping has been highly valued by the management of the railway department. It is the key to whether the train can enter the station smoothly and travel safely out of the station. The setting of intelligent iron shoes is an important solution to this key problem. [0003] If the iron shoes are not placed or placed in place when the train enters the station, it is easy to cause the vehicle to slip away. At present, smart iron shoes cannot accurately detect whether the train is slipping, nor can it calcu...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem that the false alarm rate of the slipping and slipping alarm is extremely high and the calculated slipping distance is extremely large due to the drastic changes in the magnitude and direction of the acceleration and the easy saturation in the practical application of smart iron shoes
