Patent ID: 7444208

Claim:
A electrical system wiring diagram generating system by using a computer, for generating a wiring diagram of a power system related to a plurality of electric devices, which are connected to a power supply via a plurality of power supply equipment arranged in said power system, said electrical system wiring diagram generating system comprising: a plurality of downstream side connection data generating means which generates connection data of a downstream side of said power system between the power supply equipment that are in the downstream side of power supply equipment that are capable of obtaining downstream side connection data to which said electric devices are directly connected, each of which generates connection data of downstream side of said power system between the power supply equipment with which downstream side connection data generating means is provided and said electric devices connected thereto; each downstream side connection data generating means being comprised of a processor; a plurality of transmitting means, provided at power supply equipment that are capable of obtaining downstream side connection data; each of which transmits connection data of the downstream side of said power system, together with the identification information, which is uniquely allocated to each of said selected power supply equipment and the power supply equipment that are in the downstream side of said selected power supply equipment receiving means, for receiving said information transmitted from said plurality of transmitting means; an upstream side connection data generating means, for generating connection data of, a certain number of said plurality of power supply equipments as the connection data of upstream side of said power system, which does not exist in any of said connection data of the downstream side of said power system, and of said selected power supply equipment associated with identification information, which is uniquely allocated to each of said power supply equipments, of each of said power supply equipments; and a wiring diagram generating means, which generates and displays a wiring diagram of said power system that shows the electrical connection hierarchy, from said connection data of upstream side of said power system and said connection data of downstream side of said power systems, based on said identification information of said selected power supply equipment and the others of said power supply equipments a communication network for transmitting/receiving data between above each said means.
