AI Technical Summary
Existing windshield wipers on locomotives and rolling stock require drivers to manually adjust the wiping frequency, and cannot automatically adjust according to the amount of rain. This results in cumbersome operation, poor wiping effect, rapid wear of the wiper blades, and short service life.
A humidity sensor is used to detect rainwater. Combined with a torque sensor and a pressure sensor, the controller automatically adjusts the rotation speed and interval of the wiper module, so that the wiping frequency and pressure can be adjusted in real time according to the amount of rainfall, including automatic pressure adjustment between the wiper blade and the glass.
It automates the squeegee operation, improves squeegee performance, extends the lifespan of the squeegee blade, and ensures optimal squeegee performance under different rainfall conditions.
