Photoelectric measuring transducers in environmental and objects monitoring systems

Abstract

The paper presents the theoretical foundations for calculating the primary measuring transducer of the optical type, operating as an optical locator – the design model of the optical type transducer and analytical calculation. The results of a study of a photoelectric measuring device and a signal propagation medium control system based on it are shown. An increase in the reliability of control when using measuring transducers based on optical signals can be achieved by increasing the signal power or increasing the length of the pulse sequence. This increases energy consumption and decreases control performance. Therefore, the development of methodological, structural, algorithmic and hardware means to increase the reliability and speed of the measuring channels of photoelectric converters in order to increase the efficiency of control systems is an urgent task. It is solved by using digital methods for processing optical information signals, for example, by coding signals and minimizing the code length. This increases the reliability of monitoring the parameters of objects and the environment, as well as the speed of information systems based on them. A converter has been developed and investigated for receiving and processing primary information from sensors for monitoring systems for object parameters and environmental monitoring. The analysis of modular structures of photoelectric measuring transducers for use in monitoring systems of objects and signal propagation medium is carried out.
