Changes in the pantograph’s three-axis posture (roll, pitch, yaw), wear or cracking of the contact strip, and damage to the guide horn can lead to serious issues such as poor current collection, equipment damage, or wire separation. Mechanical shocks during high-speed operation can rapidly accelerate such defects. The 2iSYS wayside inspection system automatically detects structural abnormalities in pantographs through high-speed image analysis and 3D posture estimation technology.

The roof of the train houses high-voltage equipment such as circuit breakers, insulators, and isolating devices. Damage to these components may cause arcing, fire, or power supply failure. External factors such as lightning strikes, vibration, and prolonged operation are major causes of failure.2iSYS uses high-resolution cameras and AI analysis to precisely diagnose damage to roof-mounted components.
