Provided is a hypertube transport system. Specifically, provided are a magnetically-levitated train and an infrastructure-system in which same travels, comprising: refrigerant for cooling compressed air of a hypertube train, and a compressed air cooling system utilizing the refrigerant; an apparatus and method for controlling trains operating in a vacuum tube; superconducting switches for superconducting magnets for magnetic levitation; a driving stability apparatus for the hypertube transport system; a control apparatus for trains of the hypertube transport system; and an energy harvester.

Hypertube transport system

A tube infrastructure includes a first tube; a second tube that is coupled to the first tube; and a fluid tank that is disposed to surround a coupling region of the first tube and the second tube and is filled with a fluid to seal the coupling region, wherein the fluid tank allows negative pressure to be maintained inside the first tube and the second tube.

A method for reducing data of sensor devices in a vehicle includes collecting detection data periodically from the sensor devices and calculating an average value of the data collected during a cycle. The collected data may be compared with the calculated values and a deviation with previous data may be calculated by an upper and lower value difference method. A difference between the collected data and average values may also be calculated by a deviation method. The calculated value is stored. Data from a plurality of running vehicles may be periodically transmitted to a driving control center in order to monitor devices related to operations of all of the running vehicles in near real time.
