METHOD OF SYNTHESIS OF MEASURING SIGNALS BASED ON TRIANGULAR TIME-PULSE MODULATION FOR TECHNICAL CONDITION CONTROL RADIO ELECTRONIC SYSTEMS OF WATER VEHICLES

Abstract

The article substantiates the need to increase the efficiency of operation of water transport through timely detection and elimination of possible failures of electronic systems during operation. The principle of increase of reliability of radio electronic systems of means of water transport at the expense of timely definition of possible failures is offered and investigated in the work. It is proposed to do this by improving the method of synthesis of measuring signals based on triangular time-pulse modulation to monitor the technical condition of electronic systems of water transport. It is shown that the reliability of electronic systems of water transport can be significantly increased by maintaining control parameters within the required limits by detecting and correcting deviations of these parameters in accordance with the algorithms of preventive control. The aim of the article is to develop a method for the synthesis of measuring signals based on the triangular law of modulation of time parameters of rectangular pulses, which is used with their subsequent narrowband filtering to form precise amplitude-modulated signals. The triangular law of time parameters of rectangular pulses of the carrier for the specified modulated signals is investigated. The method of synthesis of measuring signals on the basis of triangular time-pulse modulation for control of a technical condition of radio electronic systems of means of water transport is offered. It is shown that the developed method allows to carry out researches of different types of modulation of time parameters of rectangular pulses of the carrier. It is substantiated that the proposed method of triangular modulation of time parameters of the carrier with subsequent narrowband filtering provides compared to the method of binary modulation reduction of the harmonic coefficient of bending at approximately the same, rather small error of the amplitude modulation factor.
