Abstract
A method of planning a platform lift, in particular a stairlift, at a stair, the platform lift including a rail, a platform, in particular a chair, a drive unit for driving the platform along the rail, wherein the platform is attached to the drive unit. The method includes acquiring 3D stair data of a stair on which the platform lift is to be installed; calculating based on the acquired 3D stair data a path of travel of the rail, and by retrieving manufacturing constraints, in particular from a database, calculating a feasible path of travel under consideration of the retrieved manufacturing constraints.

A method of planning a platform lift at a stair, the platform lift comprising a rail, a platform, a drive unit for driving the platform along the rail, wherein the platform is attached to the drive unit, the method comprising:
- acquiring 3D stair data of a stair on which the platform lift is to be installed;
- calculating based on the acquired 3D stair data a path of travel of the rail;
- retrieving manufacturing constraints from a database;
- and
- calculating a feasible path of travel based on the retrieved manufacturing constraints;
- calculating at least one of 3D platform data representing the platform in one or several positions along the calculated path of travel, or 3D person data representing the person in one or several positions on the platform along the calculated path of travel;
- detecting a collision situation between at least one of 3D platform data or 3D person data, and environmental data;
- and
- adjusting an orientation of the 3D platform at positions along the calculated path of travel at which a collision situation is detected, by at least one of tilting the platform about a first axis or swiveling the platform about a second axis in response to the detected collision situation, to eliminate the detected collision situation between either of the 3D platform data or 3D person data, and the environmental data.
