Along with the development of network informatization and high-speed EMU smartization,the handheld mobile terminals are more and more widely used in rail transportation.This paper first outlines the current applicative status of handheld mobile terminals in high-speed EMU,and combining with current practices in EMU inspection,designs a hand-held mobile terminal system.A special wireless local area network is established in the compartment by employing the PIS system to unidirectionally transmit train data to handheld mobile terminals,and achieve real-time display of vehicle impor-tant part status and fault information by adjusting the signal switching threshold,which facilitates timely execution of safety control measures to protect network security of the vehicle.
