METHOD FOR DESIGNING THE INSTALLATION OF CABLE TRAY

摘要

PROBLEM TO BE SOLVED: To automatically decide the end point of a cable tray for retrieving the route of the cable tray from unit attribute data. SOLUTION: The space coordinates of respective electric units are converted (512) into distance space based on unit attribute data showing installation conditions such as the cost of the cable and the easiness of the installation of the cable. Namely, a distance for executing weighting is obtained based on unit attribute data. The respective electric units are developed in the distance space showing the distance. Thus, the electric units whose cable cost is high is converted to a position from which the distance becomes longer than actual distance. The types (the starting set and the end set of the cables) of the respective electric units developed in the distance space are classified (S14) and the gravity of an outline graphic containing the classified electric units is set to be the end point of the cable tray. Thus, design considering the necessary conditions (cable cost and installation easiness) deciding (S18) the end point of the cable tray can automatically be set in short time.
