Noise monitoring technology for objects in transition to the emergency state
Technology for determining values of noise variance, cross-correlation functions and coefficients of correlation between the useful signal and the noise is proposed for monitoring of the latent period of an object failure. The determined values form sets of informative attributes, which are equal to zero in the normal state of the object. In the course of object operation, values of elements that are different from zero are used to determine the moment and location of the fault. The technology has been applied in the monitoring system of the compressor unit at the Heydar Aliyev Baku Oil Refinery.
