Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings by way of specific examples.

[0038] Such as figure 1 shown.

[0039] A cable interference detection method based on geometric features, including a cable-to-cable interference detection method and a cable-to-structure interference detection method, wherein the cable-to-cable interference detection method first traverses the wiring assembly, and then obtains The harness parts in the assembly, and then search for the cables in the harness parts, obtain cable-related data, calculate the distance between the centerlines of the two cables, and take the d that has the smallest distance value i As a basis for judgment, if the minimum distance d i Less than two cable radius r 1 、r 2 The sum of the two cables interferes; if the minimum distance d i Not less than the radius r of the two cables 1 、r 2 sum, there is no interference. Use this method to continue to judge whet...

Abstract

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.

Description

technical field [0001] The present invention relates to a cable interference detection technology, in particular to the cable interference detection technology in Creo / Proe, in particular to a cable interference detection method based on geometric features. Background technique [0002] At present, the traditional manual wiring method is widely used in the development and mass production of electronic equipment. It is mainly in the stage of wiring engineer experience. The wiring speed is slow, the reliability is poor, the rework rate is high, and the inspection and maintenance are difficult. It usually takes a long period to complete the wiring of a complete machine and complete the corresponding technical documents. If the complete machine is complex, the time required will be longer, which greatly restricts the rapid development of electronic complete machines. [0003] There are some computer-aided general wiring software in foreign countries, the more representative ones...
