<P>PROBLEM TO BE SOLVED: To accurately land a car at a target floor with the displacement of the car due to a variation in the load on the car taken into account. <P>SOLUTION: This control device of an elevator counts pulse signals output from a rotation detector 20, and sets the pulse count value as a reference pulse for each floor position detected by a floor detection part 22. Based on the load on the car 13 detected by a load detection part 26, the reference pulse is corrected and stored in a position storage part 24 with the amount of the displacement of the car produced by the load on the car taken into account. Since the position of the car can be accurately detected by using the reference pulse for each floor stored in the car position storage part 24 during the actual operation of the elevator, the car 13 can be accurately landed at a desired floor at a predetermined speed without a step. <P>COPYRIGHT: (C)2008,JPO&INPIT |
