The diploma project consists of 95 pages, 65 drawings, 14 literary sources.

The diploma project is a resolution and solution of problems of designing an ultrasonic flaw detector to control the crack of a metal object of control. The task of this project is to calculate acoustic and electroacoustic tractors for control of axles of wheel pairs of rail ground transport. The diploma project contains calculations of acoustic paths, geometric dimensions of control units (piezoelectric transducer and prism) taking into account the features of control, possible errors, probability of control and electrical elements. The graphic part of the diploma project presents the structural diagram of the sensor, made on a sheet of A4, functional diagram - on a sheet of A3, component drawing of the sensor - on a sheet of A1, electrical schematic - on a sheet of A1, and specification for electrical schematic.

In this thesis, a tool for finding the coordinates of the object in space was modeled to facilitate and reduce the time of finding the defect on the site.

The first section of the thesis presents theoretical information about local positioning technologies. Also, the advantages and disadvantages of these technologies are given, as well as the choice of a certain technology for this thesis is substantiated. The second section presents the methods of local positioning and the conclusion on the application of these methods. The third section describes MEMS sensors and brief information about them, the mathematical part of the sensor data, finding the Euler angles, characteristics, as well as the choice of sensors for this thesis. In the fourth section the functional and basic electric scheme, the description of this scheme, and also algorithm of finding of coordinates of our defect is resulted.

The purpose of this diploma project is to develop an ultrasonic system of non- destructive testing, which uses the advanced functions of a smartphone to increase the capabilities of the system and reduce hardware costs.

The first section discusses ultrasonic waves and their characteristics, ultrasonic control, piezoelectric transducers, ultrasonic control methods and sensors. In the second section of this dissertation, a piezoelectric transducer is selected and calculated for the best performance. The overall dimensions of the piezoelectric transducer components have been determined. It also talks about wireless data transmission technologies.
