Turbine engine monitoring system
First Claim
1. An engine monitoring system, comprising:
- means for storing data, said storing means being attached to said engine; and
means for connecting said storing means in signal communication with an external device for the purpose of receiving information from said external device relating to the operation of said engine and storing said information in said storing means, said external device connected in signal communication with said connecting means, said connecting means providing a communication link between said external device and said external device and said storing means for transmitting said information from said external device to said storing means, said connecting means being connected in signal communication with said storing means, said external device being spatially displaced from said engine and said storing means, means for measuring an operating parameter of said engine, said measuring means being connected in signal communication with said external device, and said external device comprising a controller that is programmed to deactivate said storing means when said external device is neither transmitting signals to said storing means nor receiving signals from said storing means.

Abstract
A turbine engine monitoring system is provided which disposes a data storage device in permanent association with an engine being monitored. The data storage device comprises an electrically erasable programmable read-only memory which is contained in an enclosure and permanently attached to the engine. A connection link is provided to connect the memory device in signal communication with an external device, such as an engine control unit. The engine control unit is connected in signal communication with a plurality of transducers that enable the engine control unit to monitor the operational status of a plurality of parameters relating to the turbine engine. By permanently attaching the data storage device to the turbine engine, a lifetime information of the turbine engine can be maintained in permanent association with the turbine engine regardless of replacement of the turbine engine or its related engine control unit.
