Floor selector for an elevator car
US 3750850 A
Abstract
A floor selector adaptable for use in an elevator system which uses binary counters and comparators to provide a continuous, a discrete, and a serial advanced car position signal. The continuous and discrete advanced car position signals are used to generate an equality signal when the car must initiate deceleration in order to stop at a floor with a predetermined deceleration pattern, and the serial advanced car position signal is used to determine a coincidence of a call for service for that floor. A coincidence registered by the time the equality signal is generated initiates a request for deceleration.
