The invention provides a train sand spreading system and a control method, and relates to the technical field of rail transit. The train sand spreading system comprises a sand box and a vertically arranged cyclone sand guide cylinder, high-pressure air generated by a high-pressure blowing system carries sand in the sand box to enter the cyclone sand guide cylinder along the tangential direction and spirally descends, the cyclone sand guide cylinder and the spiral sand collecting device are both located in the eddy current heating coil and can be heated by the eddy current heating coil to dry sand, the spiral sand collecting device is arranged at the bottom of the cyclone sand guide cylinder and connected with a sand outlet aligned with a steel rail, and the width of the sand outlet is not larger than that of the steel rail. The spiral sand collecting device is arranged on the weighing sensor, the spiral sand collecting device is connected with a supplementary blowing pipe, and a temperature sensor, the weighing sensor, a high-frequency current emitter, a high-pressure blowing system and a supplementary blowing pipe are all electrically connected with a vehicle-mounted computer. The problems that in the prior art, the train sand spreading device is complex in equipment and control, and sand and energy are wasted are solved.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a train sand spreading system and a control method. Background technique [0002] In the field of rail transit, the environment around the track plays an important role in the safe operation of the train, including ice, snow, water stains and other debris that are easy to adhere to the track, or form water films and ice crystals on the surface of the track due to a humid environment. Changing the contact tightness and friction coefficient between the wheel and the rail reduces the adhesion force, causing the wheel to slide or even idling, causing wheel and rail abrasions, which has a certain impact on the safety of train operation and passenger comfort. [0003] In the prior art, the commonly used method is to sprinkle sand on the steel rail in front of the first moving wheel in the running direction through the sand spreading system to increase friction. The sand is usually...
