AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively prevent snow and ice buildup on high-speed train bogies in cold, windy, and sandy regions, which could lead to brake failure and affect the safe operation of the train.

Method used

Design an intelligent snow-proof system that includes a guide plate, a channel opening and closing mechanism, a heating element, a temperature and humidity sensor, and a control device. The system prevents snow particles from adhering by using the guide channel and the heating element, and monitors and controls the system's actions by using the temperature and humidity sensor to achieve heat dissipation and snow melting of the bogie.

Benefits of technology

It effectively prevents snow and ice accumulation on the bogies, ensuring the safe operation of trains in high-altitude, cold, and windy areas, and improving the quality and safety of train operation.
