Abstract: Current electronic equipment ATE cannot commonly monitor real-time online state during equipment works. This paper designs field embedded state monitor system with the technique of manifold noncontact sensors information fusion and wireless RS-232 serial port communication. A kind of embedded micro processor unit, S3C44B0X, and real-time operation system, μCOS –II are adopted to implement the synchronization and parallel processor of collecting the important parts of the equipment system signal and monitoring the real-time online state. It is the base of condition based maintenance and efficient leading prevention maintenance which can provide safeguard for equipment in good combat readiness state.
