Telemetry of diagnostic messages from a mobile asset to a remote station
First Claim
1. A telemeter comprising:
- a processor coupled to the output of one or more condition sensors, said processor configured to convert the output of said one or more condition sensors to a diagnostic message, and to provide said diagnostic message at a processor output, and to attach information identifying a designated destination for the diagnostic message to the diagnostic message;
a receiver coupled to said processor, said receiver configured to receive diagnostic messages transmitted in a radio frequency band;
a memory for receiving and storing said diagnostic messages from the processor and the receiver; and
a transmitter coupled to said memory, said transmitter configured to transmit said diagnostic message in a radio frequency band when said designated destination of the diagnostic message is not the telemeter.

Abstract
A telemeter for telemetry of diagnostic messages from a mobile asset to a remote station comprises a processor coupled to the output of one or more condition sensors. The processor converts the output of the condition sensors to a diagnostic message, and provides the diagnostic message at a processor output. A transmitter 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.

11. A telemetry system comprising:
-
a telemeter carried on board a mobile asset, said telemeter including;
an input coupled to the output of one or more condition sensors of said asset;
an output for providing diagnostic messages containing information related to the sensed performance of said asset;
a transmitter having an input coupled to said output of said telemeter, for transmitting said diagnostic messages in an ISM frequency band; and
a first remote station comprising;
a receiver for receiving said transmitted messages;
a processor for processing said transmitted messages; and
an output for providing information related to the performance of said asset to a device adapted to utilize said information; and
a transmitter for relaying the diagnostic message to a second remote station when a destination of the diagnostic message is not the first remote station. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
