  • a wire rope control means 400 is arranged at a predetermined position between the train entrance and the train exit of the platform.
  • the wire rope control means 400 senses the arrival and departure of a train and operates the drive means, thus selectively raising or lowering the wire ropes 200 which function to prevent passengers from going beyond a safety line.
  • the wire rope control means 400 comprises a train position sensor 410 to sense the position of a train stopped at a platform, a passenger sensor 420 to sense passengers, a position sensor 430 to sense a position of the movable assembly, and a central processing unit 440 to receive signals from the above-mentioned sensors and operate the drive means for raising and lowering the movable assembly.
  • the wire rope control means 400 preferably further comprises at least one or two of a warning alarm 450, a warning light 460 and a flashing light 470.
  • Each of the train position sensor 410 and the passenger sensor 420 preferably comprises a proximity sensor which can sense an approaching train or passengers and is preferably installed at a predetermined mounting position on the platform or on a support pillar.
  • the position sensor 430 which is a limit switch, is preferably mounted on the frame. If a passenger goes beyond the safety line or approaches a dangerous position near the track, the passenger is sensed by the passenger sensor 420. Thus, the warning alarm 450 along with the warning light 460 or the flashing light 470 is turned on to attract the passengers' attention.
  • the warning alarm 450 functions to stimulate the auditory sense of passengers and can output various sentences such as "A train is now arriving.”, "Be careful, please.” and "Wait behind the yellow safety line.”
  • the warning alarm 450 may be operated in conjunction with a broadcasting system of a station so that the warning alarm 450 can directly transmit guide information for the station to the passengers. Also, if some passengers go beyond the safety line toward the track, the warning alarm 450 may transmit warning broadcasting to the passengers.
  • the central processing unit 440 operates the motor of the drive means to raise the movable assembly.
  • the two or more wire ropes 200 are raised upwards to a height allowing passengers to pass below the ropes 200, so that the passengers can freely board.
  • the interval between two adjacent wire ropes 200 decrease such that the space utilization efficiency of the platform is improved.
  • the interval between two adjacent wire ropes 200 can decrease as the wire ropes 200 are raised, it is necessary to provide a construction to cause the interval between two adjacent wire ropes 200 to restore the original interval as the wire ropes 200 are lowered.
  • the wire ropes 200 are raised and lowered corresponding to the arrival and departure of a train, thus reliably preventing passengers from accidentally or inadvertently falling onto the track.
  • the warning alarm 450 along with the warning light 460 or the flashing light 470 is turned on to indicate the danger and attract the passengers' attention, thus preventing accidents.
  • the safety device for train platforms provides advantages in that wire ropes are installed above a safety line of a platform such that the ropes are automatically raised and lowered depending upon the arrival and departure of a train, so that passengers can be prevented from accidentally or inadvertently falling onto a track.
  • the safety device for train platforms has a simple construction and reduced installation and maintenance fees, economic efficiency can be improved. Further, due to the fact that the wire ropes are normally held in a lowered state to face passengers and are raised only when the train is completely stopped at the boarding position of the platform, the safety device has improved operational stability and reliability.
