In this system,  the rugged SIGM series fanless on-board computer intelligently analyzes the hardware equipment of the entire vehicle, checks for hardware anomalies that occur during the operation of rail vehicles, and replaces manual point-to-point detection.  Then, all the inspection data is uploaded to the ground center control room in real time to ensure the hardware abnormal equipment problems can be quickly resolved. As a mid-to-low magnetic levitation vehicle track detector, SIGM series fanless vehicle- mounted computer collects the information through the collection module installed on the train, and analyzes the collected results through the software installed in the SIGM fanless vehicle-mounted computer in advance; then it connects to the external network through a 4G router to communicate with the management center, and the SIGM series fanless box computer sends the collected and analyzed data to the management center to realize the monitoring of the train hardware system.
