<p><P>PROBLEM TO BE SOLVED: To provide an elevator system shortened in time required for reset operation when a car position cannot be acquired. <P>SOLUTION: The elevator system includes a car 1 stopping at each floor; an electric motor 3 driving the car 1; a rotary encoder 9 generating pulses according to driving of the car 1; a control device 8 controlling the electric motor 3; an RFID 7 (radio frequency identification) provided at each floor; and an RFID communication part provided to be communicable with the RFID 7 when the car 1 approaches each floor. The control device 8 stores car position determination information that associates an ID of the RFID 7 with information indicating the position of the car 1 when the car 1 stops at each floor, and refers to the car position determination information based on the ID read from the RFID 7, to recognize the position of the car 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
