In the process of controlling various materials, an important factor is control performance. The use of automated systems significantly increases the rationality of flaw detection during production. One of the most common structural materials in the industry is aluminum. Quality control is an important task, however, and there is a need for increased speeds of control. The master's thesis includes four sections. The first section consists of an analytical review of automated eddy current systems, an overview of the object of control, and theoretical calculations of the importance of eddy current flaw detection. The second section provides a calculation of the overhead differential VSP from which the matrix VSP consists. Several variants of the structural diagrams of the system have been developed to provide different control performance. Measuring channel components, such as amplifier, bandpass filter, and analog-to-digital converter, have been calculated. The following section describes the algorithm of operation. The results of the simulation of the Mathlab software environment are presented, and the probability of control is calculated based on it. The last section is about developing a startup project.

Topicality of research

Technological development has led to the improvement of traditional natural structural materials and the emergence of new ones. Industries such as mechanical engineering, metallurgy, automotive, aviation, etc. require the production of quality products that must meet high quality standards. Each of the materials has certain physical and mechanical characteristics that affect the control of products made of structural materials. In particular, in ultrasonic nondestructive testing, such a characteristic as the attenuation of the ultrasonic wave significantly affects the metrological characteristics of the measurements and controls. That is why the urgent task is to develop new research methods.

The thickness of the control objects is an important indicator, which primarily indicates the strength of the product in the further process of its operation. Ensuring the control of the thickness of products made of materials with high attenuation is based on the development of methods for precise determination of the time of propagation of ultrasonic signals in the objects of control.

Actuality of theme

The technological process in the industry is inextricably linked to its automation of technological processes. Automation is effectively used at the present stage of human development to achieve growth in resource efficiency, improve environmental quality and reliability of products. Due to the rapid
development of microprocessor technology and personal electronic computers, the functionality of which enables the use of the most advanced methods within the modern complex control systems. Microprocessor devices and electronic computers interconnected by computer and control networks using common databases allow the introduction of computer technology in the non-traditional field of activity of the enterprise, which is manifested in the integration of production processes and management. The basis of automation systems were the functionality of microprocessor control systems, in the creation of which factors such as the use of principles of integration, distributed control, software systems play a crucial role. When automating production, the object is not a separate technological process or unit, but a technological complex with complex interconnections between its subsystems.

Actuality of theme

Today, wireless data technologies have become an integral part of our lives. They are widely used by consumers of both conventional and professional equipment. The exception was not non-destructive control.
If we look at existing non-destructive devices and systems that use wireless data transmission, we will see that in the vast majority of them, such technologies are used as ancillary and not used to transmit raw data about the object of control.
In this work, wireless technologies are used not only to transmit reports on the state of the object of control, but they also help to "communicate" the sensor with the primary converter and the unit of reception and processing of information. In this work, this unit is a smartphone.
The smartphone as a complex device today has high computing capabilities, a complete set of the most widespread technologies of wireless connection, as well as a flexible software shell. It is these advantages of this type of devices that allow them to be used in non-destructive testing tasks.

Purpose: increasing the information content of medical thermograms by thermostabilizing the optical system of the thermal imager and introducing software tools for processing thermograms.

Main results: Defocusing problem of thermograph lens under the ambient temperature effect is considered in this article. Optical scheme of the IR triplet is propose, which parameters are calculated using the method of passive optical athermalization. Based on the proposed method of thermograph thermoresponsive lens filling and further optimization was designed ternary diagram of temperature-compensated infrared lens matrix with a dimension of 320x240 pixel 25x25 mkm. Thanks to this method, and the calculations in the mathematical software Mathcad has been received a number of termaltake triplets infrared spectral range combinations of 8-14 microns. At the same time was achieve thermal stabilization and system achromatization.
