Abstract:
A method in the management of data relating to an elevator structure is provided. Data is collected about the structures of the elevator, and the collected data is recorded in memory. In the method, the structures of an elevator are scanned with scanning apparatus, which collects scanning data relating to the shape of the structures being scanned, the scanning data is recorded in memory, and a three-dimensional model of the aforementioned structures of the elevator is formed on the basis of the scanning data.
Abstract:
A method and an arrangement is provided for determining the location and/or speed of an object configured to move along a controlled trajectory, in connection with which object is fitted a measuring device measuring at least the magnetic field acting on the object in its different locations, which measuring device comprises a device configured to measure the magnetic field, from the measuring data received from which device a magnetic footprint describing the magnetic field acting on the object in its different locations is formed, which magnetic footprint is recorded in connection with a teaching run, or with self-learning, for later use. The location of the object after a teaching run is determined by measuring in essentially real-time in the direction of the three coordinates X, Y, Z of the magnetic field acting on the object moving along a controlled trajectory and by comparing the measurement results to a magnetic footprint recorded in advance and also by deducing as a result of the comparison the exact location of the object on its path of travel.
