1. A wireless equipment diagnosis system comprising:
- interrogation means for transmitting interrogation waves and for receiving back as response waves the same interrogation waves after modulation in measurement acquisition means to contain diagnosis information of said equipment being diagnosed; and
said measurement acquisition means physically separated from said interrogation means and comprising means for obtaining diagnosis information of said equipment, means for receiving said interrogation waves from said interrogation means, means for modulating said interrogation waves based on said diagnosis information, and means for outputting the modulated interrogation waves as response waves for wireless transmission to said interrogation means;
wherebysaid interrogation waves from said interrogation means are used to interrogate the measurement acquisition means and to serve as medium for obtaining diagnosis information from the measurement acquisition means thereby to improve reliability of diagnosis information retrieval.

Abstract
A wireless equipment diagnosis system which can perform inspection and maintenance precisely and accurately, and which comprises sensors which measure information on each equipment being diagnosed, a transponder which transmits measured data from the sensors after modulating the measured data; a portable interrogator which acquires the measured data by receiving transmitted signals from the transponder; and a host computer which diagnoses each equipment by implementing predetermined signal processing using information stored in advance and data transferred from the acquired data.

12. A wireless data acquisition equipment comprising:
-
interrogator means; and one or more transponder means for receiving interrogatory signals from said interrogatory means and then transmitting to the interrogatory means the interrogatory signals after modulating the interrogatory signals using a modulator means with data measured by the one or more transponder means, said one or more transponder means comprising; an antenna means for receiving said interrogatory signals and for transmitting the modulated interrogatory signals to said interrogatory means; said modulator means for modulating said interrogatory signals; detector means for detecting said interrogatory signals and for outputting a detected signal represending said interrogatory signals; a control circuit means for receiving said output signals from said detector means and for generating control signals; and an interface section for transferring said detected control signals to a host computer, said interface section comprising line driver means for receiving data from said host computer; an interface circuit means for outputting said received signal from said host computer; and wherein said modulator means modulates said interrogatory signals based on output from said control circuit means.
