Title:ResearchonAutomationTestingSystemforOnboardEthernetDevicesinTrains
Introduction:
Withtheincreasingintegrationoftechnologyintherailwayindustry,manytrainsnowrelyonEthernetdevicesforvariousfunctionalitiessuchascommunication,control,andpassengerservices.EnsuringthereliabilityandperformanceoftheseonboardEthernetdevicesiscrucialforthesafeandefficientoperationoftrains.Manualtestingofthesedevicesistime-consuming,error-prone,andoftenunsustainableinarapidlyevolvingindustry.Therefore,thereisaneedforanautomatedtestingsystemthatcaneffectivelytestandvalidatethefunctionalityoftheonboardEthernetdevicesintrains.ThispaperaimstoexploreanddiscusstheresearchontheautomationtestingsystemforonboardEthernetdevicesintrains.
