AI Technical Summary
Existing testing methods for key equipment in high-speed train networks cannot effectively distinguish between normal delays caused by environmental stress and equipment failure delays, and lack the ability to assess the sub-health status of equipment, leading to false alarms and missed detection of hidden faults, which affects maintenance efficiency and train operation safety.
By constructing a multidimensional environmental dynamic stress factor, calculating the performance degradation index, evaluating the equipment status using actual response time, network load rate, and voltage deviation, and employing a dynamic threshold determination method combined with a stress reproduction mechanism, the health status of the equipment is identified.
Significantly reduce false alarm rate, improve the ability to identify hidden faults, ensure equipment quality upon deployment, and enhance maintenance efficiency and driving safety.
