Railway track maintenance requires a lot of manpower. If the maintenance is not timely or the warning is not timely, it will inevitably make the rail screws loose or landslide to bury the rail, causing traffic accidents. The product can automatically judge the looseness of the screw through resonance and repair it in time, and is equipped with an ultrasonic detector to provide accurate surrounding environment data. When the railway is buried and other emergencies, satellite feedback alerts will be sent to the railway command center to avoid traffic accidents.
