摘要： A pair of elevator cars (10, 11) traveling in the same hoistway have their positions sensed (20-23, 29-32) to provide for each a position signal (35, 37) from which velocity signals (64, 65) are derived; lookup tables (66, 61) of safe stopping distance (B, S) for braking and safeties are formed as a function of all possible combinations of velocity (V(U), V(L)) of said cars. Comparison of safe stopping distances for contemporaneous velocities of said cars with actual distance between said cars provides signals (85, 98, 99) to drop the brakes (49, 50) of one or more of the cars, and provides signals (82) to engage the safeties (18, 18a, 19, 19a) of all cars if the cars become closer or if acceleration detectors (117, 118) determine a car to be in freefall.

摘要： The device for controlling movement of a plurality of elevator cars in a single hoistway includes a door monitor module (46) that facilitates controlling movement of elevator cars (22, 24). The door monitor module (46) is configured to determine when at least one door (30) along a hoistway (26) is open. The door monitor module (46) places a first relay (52) in a selected operative state if a first elevator car (22) is stopped at a landing corresponding to the at least one open door. The door monitor module (46) places a second relay (56) in a selected operative state if a second elevator car (24) is stopped at a landing corresponding to the at least one open door. The door monitor module (46) is also configured to place both relays (52, 56) into the selected operative state if neither of the elevator cars (22, 24) is stopped at a landing corresponding to an open door (30) along a hoistway (26).
