发明名称 Elevator system
摘要 An elevator system including an elevator car, and control apparatus for controlling the speed of the elevator car, including a speed pattern generator. The speed pattern generator provides a running speed pattern and a slowdown speed pattern, and it forces the slowdown speed pattern to match the running speed pattern prior to transfer between the speed patterns, to achieve a stepless transfer therebetween. It also automatically adjusts the deceleration rate of the slowdown speed pattern prior to transfer, such that by maintaining the deceleration rate at its value at the time of transfer, the elevator car will be decelerated at a constant rate, and the slowdown speed pattern will have a predetermined value when the elevator car is at a predetermined location relative to the target floor, enabling stepless transfer at this predetermined location from the slowdown speed pattern to a landing speed pattern which is initialized to the predetermined value.
