Abstract

The invention provides a three-dimensional automatic wiring method and a three-dimensional automatic wiring device based on a rapidly-exploring random tree. The three-dimensional automatic wiring method comprises the following steps: according to an available space, a starting point and a finishing point of a cable to be arranged to obtain an initial path of the cable to be arranged; detailing the initial path to obtain a middle path; through a cable physical model, modeling the middle path to determine a final path of the cable to be arranged. Through the three-dimensional automatic wiring method and the three-dimensional automatic wiring device, cable arrangement can be achieved easily, rapidly and accurately.

Description

technical field

[0001] The invention relates to the technical field of wiring, in particular to a method and device for three-dimensional automatic wiring based on a rapidly expanding random tree. Background technique

[0002] As an important part of complex electromechanical products, cable layout design is a complicated and time-consuming task. At the same time, the quality and efficiency of cable layout design will directly affect product reliability and design cycle.

[0003] At present, there are mainly the following implementation methods for the automatic layout of cables. The first is: the wiring system using genetic algorithm, that is, the wiring problem is divided into two parts: the generation of wire harness configuration and the generation of cable path, both of which are realized by genetic algorithm, but the physical properties of cables are not considered. The second is: a sampling-based path planning algorithm, which first uses a variant of the PRM algorith...
