Problems solved by technology

This causes measurement problems and it is not easy to obtain sufficiently accurate results from the measurement
However, in these solutions, the moving object cannot detect its position when it is brought to a randomly selected position on the plane it is traveling on
Also, in solutions according to the prior art, the moving object itself cannot learn the changed orientation data
Yet another problem is that objects that deflect the magnetic field and are brought randomly into the vicinity of this type of moving object interfere with the magnetic field at that location so that the moving object can no longer detect its own precise location

Embodiment Construction

[0025] Although the embodiments of the method and arrangement for determining the position of an object moving along a controlled path of travel have been presented in relation to elevators, as already stated above, the method and arrangement according to the invention can also be applied in applications other than elevators. other places. In this case, the moving object can be for example a crane, a goods transport device or a vehicle moving along a rail or track, or some other corresponding device, the exact position of which can be obtained at a certain moment from the measurement of the magnetic field Magnetic coverage helps to determine. The object moving along the controlled trajectory may also be an object such as a tennis racket or golf club, a spear, or some other item of sporting equipment, or some other moving object.

[0026] A path of travel, i.e. a path of movement, i.e. a controlled path, or briefly, a trajectory, in this context means a curve intersecting thre...

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.

Description

technical field [0001] The object of the invention is a method as defined in the preamble of claim 1, a device as defined in the preamble of claim 11, and a use of said device as defined in claim 20, said Methods and apparatus are used to determine the position of a moving object. Background technique [0002] The arrangement according to the invention is particularly suitable for determining the exact position and / or velocity of objects moving along a controlled path of travel, such as elevator cars, cranes, goods transporters or vehicles moving along rails or rails and corresponding device or some other object. Hereinafter, the terms "path of travel" or "path of movement" of an object, or more succinctly "trajectory" mean the same. A controlled trajectory is one in which the object to be tracked is configured to travel such that it has a finite number of degrees of freedom. In this case, for example, an elevator car travels along its guide rails only in a substantially ...
