Embodiment Construction
[0050] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The smart iron shoes are installed in a large station in the north.
[0051] combine figure 1 , an intelligent iron shoe escape alarm system includes multiple pairs of intelligent iron shoes, a router, a coordinator and a monitoring host computer. The smart 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 smart iron shoes to the train wheel, and the acceleration measurement module Collect the acceleration data of smart iron shoes; the central control module receives the distance data sent by the distance measurement module and the acceleration data sent by the acceleration measurement module, and then calculates the inclination angle and vibra...

The invention discloses an intelligent iron shoe slip alarm system. The system comprises a plurality of pairs of intelligent iron shoes, a router, a coordinator and a monitoring upper computer, the intelligent iron shoe comprises a startup and shutdown module, a ZigBee communication module, an electric quantity statistics module, a distance measurement module, an acceleration measurement module and a central control module, the distance measurement module detects the distance between the intelligent iron shoe and a train wheel, and the acceleration measurement module collects acceleration dataof the intelligent iron shoe. The central control module receives the distance data sent by the distance measurement module and the acceleration data sent by the acceleration measurement module, andthen calculates the placement inclination angle and the vibration intensity of the intelligent iron shoe based on the acceleration data. Whether the distance is in place or not is judged based on thedistance from the intelligent iron shoe to the train wheel, whether the posture is normal or not is judged based on the placement inclination angle of the intelligent iron shoe, and whether escape orother service states occur or not is judged by calculating the standard deviation of the acceleration module and comparing the standard deviation with vibration intensity.
Description
technical field [0001] The invention relates to the field of railway train slip prevention, in particular to an intelligent iron shoe slip alarm system and a detection method thereof. Background technique [0002] Smart iron shoes are one of the anti-slip and anti-slip tools for railway shunting operations. Especially in my country's railways, smart iron shoes are the inevitable choice for train anti-slip methods. The train anti-slip work 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 leave the station safely. The setting of smart iron shoes is an important solution to this key problem. [0003] If the iron shoes are not placed or not placed in place when the train enters the station, it is easy to cause the vehicle to slip. At present, smart iron shoes cannot accurately detect whether the train is slipping, nor can it calculate the slipping distance with high precision. Many slipping...
