Abstract

A system for facilitating diagnosis and maintenance of a control networks on a mobile conveyance comprises one or more wireless ground stations configured to communicate over a wireless communication channel with the control network. 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 may have user terminals, a server computer, a database comprising diagnostic information relating to said control network, and a replacement parts database and/or job auction database. The local area network may also include a wide area network interface, allowing diagnostic information for the control network to be retrieved or parts to be ordered from remote vendor sites. The system may also include wireless handheld, portable equipment for allowing service personnel to perform diagnostic analysis, maintenance, and testing of the mobile conveyance control network.
