Claim:
A vacuum division management system for a tube railway system using a sealed evacuated track, the vacuum division management system comprising: a vacuum blocking screen device installed in a designated section of a tube railway, the vacuum blocking screen device being configured to be opened in a normal operation mode and configured to be closed to block a tube railway passage in an abnormal operation mode, such that the designated section blocked by the vacuum screen device has a degree of vacuum different from those of other sections; and a controller configured to monitor conditions of the tube railway and operating conditions of the train, and configured to control the vacuum blocking screen device based on the monitored conditions or a control operation, wherein the vacuum blocking screen device includes: a blocking screen configured to block the tube railway passage perpendicularly to the tube railway passage; an upper structure configured to hold the blocking screen in a standby state; a lower structure configured to seal a gap between the blocking screen unfolded from the upper structure and a lower surface of the tube railway passage; a vertical guide structure configured to guide the blocking screen in a downward direction when the blocking screen is unfolded; a blocking screen outskirts sealing part formed on outskirts of the blocking screen and configured to fill a space between the blocking screen and the tube railway passage to block a flow of air therebetween; a blocking screen driver configured to drive the blocking screen so that the blocking screen is unfolded from or held in the upper structure; a blocking screen boundary sealing device configured to block air from being circulated into a boundary between the blocking screen and the vertical guide structure; and a latch device installed in the upper structure configured to hold the blocking screen when being folded up under control of the controller.
