－ introduction －
The stability monitoring system of high-speed Multiple unit has the functions of train stability status alarm, recording and downloading, and the interconnection between the system network interface and the vehicle network. The device installs acceleration sensors on the vehicle body to collect real-time lateral, vertical, and longitudinal vibration accelerations of the vehicle body, and transmits them to the monitoring host. The host combines information such as train mileage, speed, and kilometer markers to perform time-domain analysis, frequency-domain analysis, and pattern recognition of the acceleration signal according to relevant standards, providing evaluation results of vehicle operation reliability, and sending the results to the vehicle network in real-time.
