Sensors and microsystems of Wayside Monitoring System for rolling stock in motion

摘要

The paper presented is dedicated to the development and application of sensors and microsystems for evaluating various parameters of rolling stock in motion. The intended purpose of such a system, comprising of the described sensors and microsystems and also known as Wayside Monitoring System for Rolling Stock in Motion, is to identify the current overall condition of the railway vehicles, including hot boxes (axle bearings) and brakes (wheel brakes and disc brakes), wheel defects (flat spots, out of roundness, polygonization, etc), dynamic weighing and load distribution, etc. All of these could compromise the safety of the railroad traffic, leading to accidents such as vehicle derailment and increased wear and damages of the tracks.
