Abstract: A real-time spectrum analyzer for measuring time domain data sampled from an input signal includes a processing unit and a density histogram memory unit. The processing unit includes an FFT engine, a frequency mask detector and a frequency mask gate. The FFT engine performs FFTs on the sampled time domain data to provide FFT spectra, each FFT spectrum including multiple FFT points.

The frequency mask gate receives the FFT spectra and the gate control signals, and outputs only select FFT spectra that contain at least one FFT point that meets the trigger condition in response to the corresponding gate control signal. The density histogram memory unit stores the select FFT spectra for generating in a density histogram.

Abstract: An overheating detection processing system monitors in real time and stores data samples from the different types of power plant overheating detectors. The system determines a likelihood of whether a stored detector output sample reading, alone or in combination with other readings, is indicative of monitored power plant equipment overheating. The system references previously stored information in an information storage device that associates respective types of detector sample reading levels with equipment overheating. The system also compares a combination of stored sample readings and establishes overheating determination confidence levels. The confidence levels information is combined to derive an overall confidence level of whether the power plant equipment is overheated. An overheating alarm response is initiated if an overheating condition is determined at any confidence level. Additional responses are made based on a combination of calculated confidence levels.
