Active Protection Technology of Depot Automatic Zones in Urban Rail Transit FAO Vehicle Base

Abstract

[Objective] Setting up underpass or overpass in front or inside the urban rail transit depot for personnel's access to the automatic zone requires large project investment, being prone to affect personnel evacuation and cause safety hazards due to the long walking distance and extremely inconvenient operation. Therefore, it is necessary to make further research on protection technology that does not use underpasses or overpasses in the depot automatic zone. [Method] Due to the problems such as hazards of fire safety, inconvenient access, complicated management procedure, large project investment and construction difficulty under traditional protection strategy for the depot automatic zone in FAO (fully automatic operation) vehicle base, the active protection technology is put forward. The depot automatic zone is arranged according to the concept of active protection technology. The active protection operation process and the system architecture of this technology are introduced in detail. [Result & Conclusion] The active protection technology for the depot automatic zone in the FAO vehicle base is as follows: the electric retractable door in the middle channel is adjusted from normally closed state to normally open state. The underpass or overpass is canceled and the personnel and maintenance vehicles can enter the automatic zones through the middle channel. After the active protection technology is used, the personnel can pass the middle channel normally when no vehicle entering or exiting in the depot. Using active protection technology reduces the walking distance of both the personnel and maintenance vehicles, eliminates fire safety hazards, improves operation management efficiency and reduces project investment and construction difficulty.
