<P>PROBLEM TO BE SOLVED: To provide a control device of an elevator for omitting mounting adjustment for a last floor reduction gear and outputting an accurate speed reducing command in traveling to the final floor. <P>SOLUTION: This control apparatus includes: a top end distance measuring device 13 set in a car 1 of the elevator and radiating a transmit wave toward the top end part of a hoistway to measure the top end distance from the car 1 to the top end floor on the basis of time elapsed from the radiation of the transmit wave to receiving of a reflected wave from the top end part; a bottom end distance measuring device 14 set in the car 1 and radiating a transmit wave toward the bottom end part of the hoistway to measure the bottom end distance from the car 1 to the bottom end floor on the basis of time elapsed from the radiation of the transmit wave to receiving of a reflected wave from the bottom end part; a car control device 15 for deciding the position of the car by comparing an addition value of the top end distance and the bottom end distance with the previously stored height of the hoistway; and a speed control device 16 for controlling the traveling speed on the basis of the position of the car 1. <P>COPYRIGHT: (C)2004,JPO |
