ABSTRACT:
This process allows for the automatic production of an electrical wiring diagram on which are located boxes, each representing a component used in an electrical device, connecting lines, each representing an interconnecting cable and connecting terminals corresponding to a possible connection point between a connecting line and a box, the boxes being arranged along an axis of abscissas and an axis of ordinates. The process includes the following steps: input of the components and cables to be represented on the wiring diagram, each component being of a predetermined type; generation and resolution of a first system of equations to optimize the relative positioning of the boxes on the axis of abscissas and their orientation; generation and resolution of a second system of equations to optimize the relative placement of the boxes and of the terminals in terms of the axis of ordinates; generation and resolution of a third system of equations to place the boxes and the cables in an absolute manner, and production of the wiring diagram corresponding to the numerical data obtained by the resolution of the systems of equations.
