APPLICATION OF SOFTWARE FILTERING OF REFERENCE SIGNALS TO INCREASE THE SENSITIVITY OF AUTOMATED GEODYNAMIC MONITORING OF OIL PRODUCT LEAKAGES AT FUEL AND ENERGY SECTOR FACILITIES

This article is devoted to the development and practical application of the algorithm for software filtering of pulse noise in reference signals of automated monitoring systems for oil leaks at fuel and energy complex facilities to increase their sensitivity. This algorithm uses a combination of two hardware methods for suppressing interference from pulse power supplies, implemented in software: limiting high-amplitude voltage surges based on available a priori information and smoothing the shape of signals when the amplitudes of adjacent samples go beyond the permissible limits. Illustrations of the algorithm's operation in the time and frequency domain are provided, proving the possibility of reducing the noise component in the spectra of reference signals to 10 dB and discrete parasitic spectral components to 5 dB.
