China is in the period of rapid development of railways, and as the years end at 2017, the business mileage of railways in China reaches 13.1 kilometers, wherein 2.9 kilometers of high-speed rails account for more than 2/3 of the total mileage of the whole world, and the country has the longest high-speed rail mileage, the highest transportation density and the most complex network forming operation scene in the world. The increase of the departure density of the station and the increase of the passenger flow volume and the pressure of the station safety production are increased.
When the train moves forward, the air around the train is carried forward, and the closer to the train, the faster the air flows. When a person is on the platform, the air flowing at high speed close to the train and the air flowing slowly behind the back of the person form a pressure difference which pushes the person to the train, and the personal casualty accident is easy to cause. Therefore, the station requires passengers to wait within the safe white line of the railway platform; before the train is driven, if foreign matters fall into a gap between the train and a platform and are not found in time, driving accidents can be caused.
