Abstract
Disclosed is a method for monitoring a technical device, according to which a number of operational signals are detected during operation. A mean operation signal value is formed using said operation signals, and at least one standard operational signal is generated therefrom. The standard operational signal is ultimately compared to a reference value range of the respective operational signal.

8. A method for monitoring a technical device, comprising:
-
detecting a plurality of operational signals of the technical device;
determining a mean operational signal value using at least some of the operational signals;
determining a normalized operational signal for at least one operational signal where the normalized operational signal contains a deviation of a current value of the operational signal from the mean operational signal value; and
comparing the normalized operational signal with a reference value range of the relevant operational signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for monitoring a combustion chamber burner flame temperature of a gas turbine engine, comprising:
-
detecting an operational signal of the gas turbine engine that corresponds to the combustion chamber burner flame temperature of the gas turbine engine;
determining a mean operational signal value of the detected operational signal;
determining a normalized operational signal based on the detected operational signal where the normalized operational signal contains a deviation of a current value of the operational signal from the mean operational signal value;
comparing the normalized operational signal with a reference value range of the detected operational signal where the reference value range is determined multiple times while the gas turbine engine is operating and the normalized operational signal is compared with the current reference value range for each determination of the reference value range; and
comparing the current value of the detected operational signal with a predetermined monitoring threshold value.
