The embodiment takes the transportation pipeline 2 built in the tunnel as an example, and the implementation manner of the transportation system is explained in detail.

The conveying pipeline 2 is a closed pipeline, the vacuum degree in the conveying pipeline is a first preset value, and the first preset value is smaller than the standard atmospheric pressure. When the value of the first preset value is 0.01 atm to 0.5 atm, the transport pipe 2 may be referred to as a low vacuum pipe. The platform 4 comprises a platform passenger loading and unloading area 41 and a platform rail area 42, and two ends of the platform rail area 42 are respectively communicated with the transportation pipeline 2. The track 3 is arranged in the transport pipe 2 and the station track area 42.

When the air shaft partition door 21 is opened, the air shaft 6 is communicated with the transportation pipeline 2. During vehicle operation, the air shaft partition door 61 is closed to ensure that the vacuum in the transport pipe 2 meets vehicle operating requirements.

When the vehicle breaks down or fires and other accidents happen, if the vehicle has enough power to drive into the platform 4, passengers normally get on or off the vehicle from the platform 4 to evacuate and escape; if the vehicle does not have enough power to drive into the platform 4, the vehicle is stopped at the air shaft 6 nearby, the air shaft partition door 61 is opened, air is supplied into the conveying pipeline 2 through the air shaft 6, so that a normal-pressure environment is formed in the conveying pipeline 2, and passengers get off the vehicle and evacuate from the air shaft 6 for escape.

Passengers arrive at the normal pressure environment in the station from the normal pressure environment in the magnetic levitation vehicle 7 and arrive at the station hall layer of the underground layer through the stairs, so that the passengers can get out of the station or transfer. After the passengers finish getting on or off the train, the doors are closed, and the train drives off the platform 4.

The control system is connected with the interval sealed door 5 and the air shaft partition door 61, and the control system calculates the opening and closing time of the interval sealed door 5 according to the vehicle speed. When the vehicle enters the station entering space, the air resistance of the normal pressure environment is combined with the braking force of the vehicle, so that the vehicle is decelerated to enter the station. The control system is also used for controlling the action of the vacuum pump in the air shaft 6 so as to adjust the vacuum degree in the transportation pipeline 2 to meet the requirement.
