Cable interference detection method based on geometrical characteristics

The invention provides a cable interference detection method based on geometrical characteristics. The method is characterized by comprising a cable and cable interference detection method and a cable and structure element interference detection method, wherein during the cable and cable interference detection, firstly, a wire distribution assembly body is traversed, then, a wire harness part in the assembly body is obtained, next, cables in the wire harness part are searched, cable relevant data is obtained, the distance between two cable center lines is calculated, and the smallest distance value is used as the judging basis. During the cable and structure element interference detection, the wire distribution assembly body is firstly traversed, the space position data and the profile data of a structure element are obtained, the cable center lines are subjected to discrete representation in a space coordinate point form, and then, the smallest distance between the structure element and the cable discrete coordinate is judged. The cable interference detection method has the advantages that the computer aided three-dimensional wire distribution accuracy and the engineering practicability can be greatly improved, and the reliability and the stability of cable wire distribution are improved.
