Background. The article attempts to expand the functionality of informationmeasuring systems designed for remote measurement and analysis of vibration processes occurring in man-made and natural objects. The relevance of this problem is due to the fact that vibration processes contain a lot of information about the state of the test object. Currently known information measurement systems obtain only a small part of this information. Materials and methods. Studies of the amplitude of vibration displacement of the surface element of the test object and its dynamics were carried out by repeated measurements of the image area of a circular fragment, followed by testing the null hypothesis using mathematical statistics methods. Results. A principle is formulated for estimating the root-mean-square value of the vibrational movement of a surface element of a test object along an arbitrary trajectory based on an analysis of the vibrational blurring of the image of a round test fragment. A technique is proposed for experimentally determining the frequency of detection of a vibration signal of a monitored object, based on the results of which a decision is made on the possibility of vibration monitoring of a specific object in order to provide early warning of impending equipment failures, man-made accidents and natural disasters. Conclusions. A method has been developed and experimentally tested to study the possibility of identifying the pre-emergency state of a test object by the vibration increment of the image area of a round test fragment. The possibility of monitoring the power supply «CZ» of the computer in order to identify its pre-emergency state by an information-measuring system based on image analysis of a round-shaped test fragment with vibration blur has been confirmed.
