Elevator system with a device for determining the position of an elevator cabin and method to operate the elevator system

摘要

#CMT# #/CMT# The installation includes an equipment (8) for detecting a cage position and consisting of a code mark pattern (80) and a sensor device (81). The code mark pattern is mounted along the travel path of a cage and consists of multiple code marks (83). The sensor device is mounted at the cage and contactlessly scans the code marks by sensors (85). The code marks are arranged in a single track and the sensors are arranged in a single track. #CMT# : #/CMT# An independent claim is included for a method of operating a lift installation. #CMT#USE : #/CMT# Lift installation. #CMT#ADVANTAGE : #/CMT# Enables to clearly detect the transition between differently poled code marks as a zero transition of the magnetic field. Enables accurate scanning of code mark pattern by a sensor device at low cost without security and reliability being impaired. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the schematic drawing of the construction of a part of equipment for determining cage position, with sensor device and code mark pattern. 8 : Equipment 80 : Code mark pattern 81 : Sensor device 83 : .
