Elevator Control Apparatus And Method For Estimating Expansion/Contraction Amount Of Governor Rope
Abstract: Provided is an elevator control apparatus including a current position calculator configured to calculate a current position of a car based on a counter value of a governor encoder. The current position calculator is configured to: calculate a movement amount of the car based on the counter value of the governor encoder, the movement amount being calculated for a period of time from when the car starts to move from a state in which a landing plate detector detects one of landing plates installed at respective floor positions of a building and the car is stationary until the landing plate detector ceases to detect the landing plate; and estimate a governor rope expansion and contraction amount of a floor from which the car starts to move by estimating a counter error of the governor encoder caused by expansion or contraction of the governor rope by comparing the calculated movement amount with an actual length of the landing plate.
