The invention relates to an elevator system, comprising: an elevator shaft provided with a plurality of floors on the outer edge in the height direction at intervals; a control cabinet comprising a power supply module; a cable arranged on the shaft wall of the elevator shaft and electrically connected with the power supply module; a plurality of lacing and shielding structural members hooped on the cable and arranged at intervals, wherein the sections, hooped by the lacing and shielding structural members, of the cable form lacing sections, and the lacing sections are arranged in one-to-one correspondence with the floors; a car movably arranged in the elevator shaft; and a position recognizer arranged on the car and capable of being matched with the cable in a magnetic induction manner. The position recognizer sequentially passes through the lacing sections corresponding to different floors and the adjacent non-lacing sections, and the obvious intensity change of a magnetic field can be accurately sensed; and the length of the part, passing through the lacing section corresponding to the current floor, of the car can be calculated in combination with the running speed parameter of the car, that is, the current actual floor position of the car can be determined.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator system. Background technique [0002] At present, elevators have been widely used in high-rise or even super high-rise buildings. Conventional elevators are mainly composed of machine room, elevator shaft, car and accompanying cables. The machine room is usually installed at the bottom or top of the elevator shaft. A control cabinet is arranged in the machine room. One end of the accompanying cable is connected to the control cabinet and the other end is connected to the car. When the car moves up and down in the elevator shaft, the accompanying cable will move synchronously with the car, and the accompanying cable can transmit the electric energy and signal in the control cabinet to the related equipment on the car. [0003] As the height of the building floor continues to increase, the operating range of the vertical elevator is also continuously increasing, whic...
