Abstract
A system for facilitating diagnosis and maintenance of one or more control networks located on a mobile conveyance comprises one or more wireless ground stations configured to communicate over a wireless communication channel with a control network via a wireless interface. A local area computer network receives and responds to messages to or from the control network via the wireless ground stations. The local area computer network comprises one or more user terminals, a server computer, a database comprising diagnostic information relating to said control network, and, optionally, a replacement parts database and/or job auction database. The local area network further includes a wide area network interface, which allow either additional diagnostic information relating to the control network to be retrieved, or parts to be manually or automatically ordered from remote vendor sites. The system may also include wireless handheld, portable equipment capable of communicated with the local area network and/or wide area network, for allowing service personnel to perform diagnostic analysis, maintenance, and testing of the control network(s).
