INVESTIGATION OF THE METHOD OF AUTOMATIC COMPENSATION OF TREND COMPONENTS OF PHASE SIGNALS IN SYSTEMS OF PHASE-METRIC CONTROL OF GEODYNAMIC PROCESSES
(pp. 54-59)

Abstract. Geodynamic monitoring is widely used to monitor and control the state of various objects, as well as to detect and evaluate their changes over time. The software and hardware systems that implement it for tracking the geodynamics of objects over long time intervals should effectively highlight the trend component in the processed data. A promising way to implement geodynamic monitoring is the use of phase-metric methods of geoelectric control. The block diagram of the phase change detection path using these methods contains a differential amplifier, a phase detector, a low-pass filter, and a highly stable reference oscillator. To eliminate an undesirable constant phase shift based on this method, it is proposed to use an automatic compensation method that allows the system phase to be adjusted automatically in real time. The result of using the auto compensator is the formation of a "new" reference signal for the phase detector, excluding the formation of these phase shifts in its output signal. To illustrate the proposed approach, the use of software implementation of automatic compensation of unwanted shifts to identify a trend in phase signals obtained during geodynamic monitoring of the near-foundation zone of a structure is considered, which has shown its effectiveness and the possibility of further practical use.

Keywords: geodynamic monitoring, trend, geoelectrics, phase-metric method, automatic compensation.
