The sand in the sand box is scattered on the track, which can form a rough medium on the wet and slippery track surface, thereby increasing the friction and improving the adhesion coefficient between the wheel and the track to ensure the safety of vehicle driving. In the field of rail transportation, such as locomotive, high-speed rail, bullet train, subway and engineering operation vehicle, the vehicle is equipped with a sand box. During the operation of the vehicle, the driver controls the sanding valve of the sand box to open through the control console, so as to sprinkle sand on the track to increase the wheel-rail friction and ensure the braking capacity.
