Development of Trackside Dynamic Monitoring System Equipment for High Speed EMU Operation Quality Based on 5G Millimeter Wave
In order to better monitor the polygonal wear of wheels,ensure the operational quality,and meet the ground dynamic detection requirements of high speed EMU(Electric Multiple Units)wheelset status,a high speed EMU operation quality trackside dynamic monitoring system equipment based on 5G millimeter wave was designed and developed,and an overall installation plan was provided.The equipment is mainly composed of a mechanical test platform composed of a non perforated shear sensor and a structure-coupled 2-dimensional pad sensor,a 5G millimeter wave wireless data acquisition module,a 5G millimeter wave base station,an image car number camera,a edge computing equipment box,a solar power supply device,etc.In terms of measurement principle,the equipment adopts a fully continuous"shear force + support force"composite measuring area wheel-rail vertical force measurement method.In the structural design of perception components,the structural characteristics of high speed railway main type fasteners were fully considered,and a structure-coupled force sensor was developed.A low-power,miniaturized distributed data acquisition module has been designed for the sampling and transmission of wheel-rail force signals,and 5G millimeter wave technology has been integrated to achieve low delay,high reliability,and large bandwidth data transmission.
