Diagnostics/prognostics using wireless links

A system, comprising:

• a processor;
• a wireless signal transceiver in communication with said processor;
• one or more sensors collectively configured to detect two or more operating parameters of a vehicle;
• one or more tag means for receiving the operating parameters from said sensors and wirelessly communicating the operating parameters to said wireless signal receiver;
• a processor-readable medium, in communication with said processor, encoded with programming instructions executable by said processor to:
• develop a report signal as a function of the operating parameters;
• and
• send said report signal to a display device.

A system for maintaining a plurality of vehicles, comprising:

• a management center;
• and
• an on-board subsystem on each vehicle, each said subsystem comprising:
• one or more sensors that collectively sense a plurality of operating parameters of the vehicle;
• one or more transceivers, each in communication with one or more sensors, that communicate a data signal indicative of the operating parameters in response to an interrogation signal;
• one or more interrogators configured to selectively produce the interrogation signals and receive the data signals;
• a processor, in communication with said one or more interrogators and a computer-readable medium, wherein the computer-readable medium is encoded with programming instructions executable by said processor to:
• perform analysis of the health of one or more portions of the vehicle based on the operating parameters indicated by the data signals to produce one or more result signals;
• and
• control production of interrogation signals by said one or more interrogators;
• and
• communications hardware in communication with said processor to communicate at least one of said one or more result signals to said management center.
