ELEVATOR SYSTEM WITH INDEPENDENT LIMITING OF A SPEED PATTERN IN TERMINAL ZONES |
摘要 |
A feedback controlled elevator system driven by a traction drive motor in response to a speed pattern provided by a car controller. The speed pattern is limited when the car approaches a terminal floor within a predetermined terminal slowdown zone adjacent to the terminal floor. A pattern limiting signal is provided in response to digital integration of shaft encoder signals which provides a digital position "x" of the car within a terminal zone. The position "x" of the car is then used to access a read-only-memory which contains the maximum car speed for the specific location of the elevator car. The value from the read-only memory is used to limit the speed pattern. |
