Title:
ELEVATOR CONTROL DEVICE AND ELEVATOR
Document Type and Number:
Japanese Patent JP3268483
Kind Code:
B2
Abstract:
PURPOSE: To improve the high reliability of the stop position correction control for correcting the car stop position when passengers get on or off.
CONSTITUTION: A position sensor 2 is provided on an elevator mechanism section 1, and it detects the present position of a car and inputs the detection result to a control device 5. A deviation calculating device 3 in the control device 5 subtracts the output signal of the position sensor 2 from the output of a car target position generator 4 and outputs the result to a gain device 6. An acceleration estimator 11 is provided in the control device 5, and it calculates the estimated car acceleration based on the car position signal. A subtracting device 10 subtracts the output of a gain device 9 from the output of the gain device 6 and outputs the value to an elevator driving device 7. The elevator driving device 7 operates the elevator mechanism section 1 at the speed proportional to the input to properly keep the car stop position.
