[0002] As my country's intercity / high-speed rail network gradually improves, and the capacity and volume of transportation continue to increase, intercity / high-speed rail travel has gradually become the first choice for more and more domestic passengers. With the increasing number of intercity / high-speed rail passenger flow and the number of trains running, the time interval between train runs has been gradually shortened. At present, the time for intercity / high-speed rail trains to stop at stations has generally been compressed to 2 to 3 minutes. As a result, most stations will have to change the original management method of waiting for the train to enter the station and then checking tickets to enter the station, and change to a method of checking tickets in advance to allow passengers to enter the platform and wait for the train to enter the station and board the train.
