Telemetry of diagnostic messages from a mobile asset to a remote station

摘要

A telemeter for telemetry of diagnostic messages from a mobile asset to a remote station comprises a processor (150) coupled to the output of one or more condition sensors (320). The processor converts the output of the condition sensors to a diagnostic message, and provides the diagnostic message at a processor output. A transmitter (118) is coupled to the processor output. The transmitter is adapted to transmit the diagnostic messages in the Industrial, Scientific, Medical (ISM) frequency band. An exemplary embodiment of a telemetry system of the invention comprises a telemeter adapted to transmit diagnostic messages in the ISM frequency band, and a remote station including a receiver for receiving the diagnostic messages in the ISM band. <IMAGE>
