Positional information display system

A positional information display system comprising a control device of an industrial machine, a conversion information calculation device which calculates conversion information between different coordinate systems, and an image information control device which causes positional information to be displayed on a display device having a touch panel,

• wherein the control device includes:
• a coordinate information notification portion which notifies of coordinate values of each axis of the industrial machine to the image information control device;
• wherein the conversion information calculation device includes:
• a conversion information calculation portion which calculates conversion information representing a position and/or posture of a first coordinate system in a second coordinate system, with coordinate values of each axis of the industrial machine as variables,
• a conversion information notification portion which notifies the conversion information to the image information control device,
• a graph generation portion which generates a graph constituted by nodes showing a machine configuration of the industrial machine,
• a control point coordinate system insertion portion which inserts a control point and coordinate system into the graph, and
• a node information notification portion which notifies of node information which can be selected as a coordinate system to the image information control device;
• wherein the image information control device includes:
• a coordinate information conversion portion which calculates a position and/or posture of the first coordinate system in the second coordinate system using the conversion information and the coordinate value of each axis,
• a positional information calculation data setting portion which sets data for calculation of positional information for visually displaying on the touch panel a position and/or posture of the first coordinate system in a third coordinate system of the display device,
• a positional information display data calculation portion which calculates data for display of the positional information on the display device using the data for calculation of the positional information,
• a positional information display data notification portion which notifies of the data for display of the positional information to the display device,
• a node selection portion which selects a node corresponding to the coordinate system displayed, and
• a selected node notification portion which notifies of a selected node to the conversion information calculation portion of the conversion information calculation device;
• and
• wherein the conversion information calculation portion calculates conversion information which represents the position and/or posture in a coordinate system corresponding to a selected node.
