  • Elevator installation and method for determining and analyzing an elevator car position
    Patent number: 7562747
    Abstract: An elevator installation with at least one car includes at least one device for determining a position of the car and a method of operating such an elevator installation. The position determining device has a code mark pattern and a sensor device. The code mark pattern is arranged along the length of travel of the car and consists of a multiplicity of code marks. The sensor device is mounted on the car and has sensors contactlessly scanning the code marks. The code marks are arranged in a single line and the sensor device comprises at least two sensor groups which are separated from each other perpendicular to the line of the code marks, which makes reading the code marks possible even if there are lateral displacements between the sensor device and the line of the code marks.
