[0003] At present, the wiring design of the aircraft EWIS system needs to be carried out in the three-dimensional mechanical design environment and the electrical design environment respectively. These software environments can provide relatively complete design means and modeling methods in several links in the wiring design process, but in the current aircraft EWIS Under the systematic wiring design process, various design data in the mechanical and electrical design software environment lack an effective technical way to convert and transfer according to the EWIS wiring design requirements, resulting in a very cumbersome wiring design process that requires a lot of manual repetitive design work, which cannot Realizing rapid and automated wiring design seriously affects the wiring design cycle and quality, so it is necessary to establish a new and effective automated aircraft wiring design method to improve the quality and efficiency of aircraft EWIS system wiring design
