  • Elevator system
    Patent number: 5637841
    Abstract: An elevator system includes a CPU to dictate speed signals during a normal elevator car run, and a normal terminal stopping device (NTSD) to dictate maximum allowable speeds approaching the top and bottom terminal floors. The NTSD system normally operates in monitor mode, where the NTSD profile has the same deceleration rate as the normal speed dictation signals. Should the normal speed dictation signal exceed the NTSD value, the NTSD system switches to a violation mode, having a rate of deceleration greater than the normal deceleration.A plurality of vanes are located in the hoistway to provide absolute position signals for generating NTSD values. Preferably, when operating in the monitor mode, the NTSD software calculates pseudo checkpoints between the actual vanes, to readjust the NTSD values. Also, preferably the NTSD values during jerk into deceleration are calculated based on the constant deceleration rate during slowdown.
