Framework dataset for an escalator or a moving walkway

A method for visualization of a three-dimensional truss dataset of an escalator or moving walkway using a computer program executed in a computer system, the method comprising:

• determining client-specific configuration data with information at least on a conveyor height and on a step width for an escalator or moving walkway;
• selecting, by the computer program or by manual input, a type-specific, two-dimensional layout based on the client-specific configuration data, wherein this two-dimensional layout comprises, in a plane of a three-dimensional space, the guideway of a revolving conveyor chain and has a defined origin, wherein the type-specific, two-dimensional layout is selected from among a plurality of different type-specific, two-dimensional layouts, each of the plurality of different type-specific, two-dimensional layouts corresponding to a different type of escalator or moving walkway, and wherein a conveyor height associated with the type-specific, two-dimensional layout is different than the conveyor height of the client-specific configuration data;
• adjusting the type-specific, two-dimensional layout, starting from the origin, such that the conveyor height of the type-specific, two-dimensional layout matches the conveyor height of the client-specific configuration data;
• subdividing the guideway of the adjusted type-specific, two-dimensional layout into a plurality of division portions, wherein a length of each of the division portions, except for a remnant division portion, corresponds to the spacing of two sequential hinge points of a type-specific conveyor chain, and wherein a length of the remnant division portion is less than that of the other division portions;
• further adjusting the type-specific, two-dimensional layout by enlarging the circumferential length of the guideway until the remnant division portion has the same length as each of the division portions;
• and
• generating and visualizing a three-dimensional truss data set based on the further adjusted type-specific, two-dimensional layout.
