Temperature detector having different types of independent sensors

摘要

The present disclosure is directed to a temperature detector for detecting a temperature of a component. The temperature detector may receive a first signal indicative of the temperature of the component, with the first signal being received from a first type of temperature sensor. The temperature detector may further receive a second signal indicative of the temperature of the component, with the second signal being received from a second type of temperature sensor different from the first type of temperature sensor. The temperature detector may combine the first and second signals to generate an output indicative of the temperature of the component.

主权项

1. A method for detecting a temperature of a component, the method comprising:
receiving a first signal indicative of the temperature of the component, the first signal being received from a first temperature sensor, the first temperature sensor being a first technological type of temperature sensor having first principles of operation; receiving a second signal indicative of the temperature of the component, the second signal being received from a second temperature sensor, the second temperature sensor being a second technological type of temperature sensor having second principles of operation different from the first principles of operation; determining a reliability of the first and second signals by one or more of;
(1) evaluating the consistency of the first and second signals,(2) determining whether one of the first and second signals is an outlier,(3) determining a signal-to-noise ratio for each of the first and second temperature sensors,(4) determining a false alarm rate associated with each of the first and second signals and(5) determining a frequency of maintenance required for each of the first and second temperature sensors; and combining the first and second signals after determining their reliability to generate an output indicative of the temperature of the component.
