The technology belongs to the field of cable network design methods and specifically relates to a design method of digital cable network based on CHS. The method comprises following steps: the design of a principle layout, the design of electrical schematic diagram, calculation of the length of various branches of the cable network, generation of the cable network. The invention realizes the direct recursion and utilization of the design information, and reduces the repetition input of the design information in the information transmission process, thus greatly reducing the cable network design cycle and improving the quality of the design technology.
