The electronic funds of distributed systems are grouped in stand-alone buildings with protection from unauthorized access, which plays an important role in ensuring the reliability of their functioning from outside electromagnetic fields and internal parasitic electromagnetic communication. The research has therefore been conducted to develop methods and algorithms of automated synthesis models to resolve problems in electrodynamics and calculation of efficiency of shielding.
Analysis of the models for forecasting and calculation of electronic funds’ reliability is connected with the definition of states of component elements recommended in national and foreign standards. This analysis is accompanied by the development of mathematical models of intensities element failures caused by degradation processes, as well as the creation of a method of calculating the intensity of failures of constructive-technological parameter elements.
Distributed systems are characterized by a division of functions and resources between many electronic components. A failure of one node therefore does not lead to a complete halt of the whole system. A typical distributed system is the main pipeline, to which the final part of the report is devoted.
Purpose of the work
The aim of the work is to increase the efficiency of the process of automated design of electronic resources, diagnostics systems, and monitoring the technical condition of distributed systems. The project also aims to reduce the time and cost spent on their creation through the use of computer simulation tools, including electromagnetic processes in designs of electronic equipment and evaluation of the effectiveness of shielding with the fulfilment of the required level of reliability.
Empirical basis of the research
To verify the adequacy of the calculation of the shielding efficiency of electronic tools, 4 up aperture panels were designed. One of the solid panels is used as a back wall in cases where required, with only one sensor. A second continuous panel was used together with the first to test the accuracy of the screen. A wire sensor (monopole) diameter 0.021 inches (0.5334 mm) was mounted on the bottom for measuring the electric field inside the box.
Technical support for data processing is laser terrestrial. The optimum composition of the technical equipment required to operate THE Collection and processing: a Pentium processor with a frequency of 2 GHz or more; 1 GB RAM; hard disk 80 GB or higher; video card and monitor that support a resolution no less than 1920x1080 pixels; a Canon EOS 550D camera; and a GlobalSat BU-353 GPS receiver. Running the programme requires the size of the paging file to be maintained at more than 2048 MB.
Our main result is the creation of a methodology for automated reliable design of electronic resources (ES) of remote monitoring distributed systems. The main scientific theoretical and practical results of the work consist of the following:
• method and algorithm automated synthesis of models to calculate the effects of electromagnetic impacts on ES have been developed
• practical implementation of the developed methods and algorithms in the form of automated subsystems ensuring the effectiveness of shielding ES on the basis of numerical modelling of electromagnetic processes, including a developed reference database for the electromagnetic parameters of various structural materials ES
• developed a procedure to ensure the effectiveness of shielding constructions ES on the basis of numerical modelling of electrodynamic processes
• development and implementation of software at industrial enterprises and institutions of higher education
To increase the accuracy of automated reliability calculations, the following works have been performed in the present research: development of mathematical models of field failure rate elements of ES due to degradation processes; creation of a software tool to calculate the intensity of element failures;
development of a method to estimate the intensity of element failures when designing EA.
As a result of research, issues regarding safe operation of the main pipelines were considered. To increase the security of their functions the following were developed:
• a methodology to monitor pipelines with the use of complex laser terrestrial and mobile ES measurements with the use of small aviation
• a unified methodology (algorithms and software) to measure distance from an aircraft and ground-based wireless sensory networks and their joint processing
• techniques for using geographic information systems for mobile monitoring of pipelines, including with the use of GLONASS
Implementation of research results
The basic research results were implemented at OAO S.P. Korolev Rocket and Space Corporation Energia, and in the educational processes of MIEM HSE in the following areas: Design and Technology in Electronic Engineering, Information and Communication Technologies and Communication Systems, and Informatics and Computer Engineering, covering the following disciplines: automation of design and technological engineering, reliability, ergonomics and quality industrial control systems, automated systems for ensuring the reliability and quality of spacecraft electronics, the reliability of electronic means, bases for constructing electronic means, electronic means elements and components, and design practices to ensure EMC.
Comprehensive technical, economic and social effects in practice design of structures EA were expressed: speed of rapid analysis of the electromagnetic field inside the body of the EA for the external field, and the ability to determine the effectiveness of shielding; improvement of the reliability of the developed equipment from reducing the impact of human factors on the accuracy of simulation results from the use of friendly specialized interfaces input data and presentation of analysis results; reducing the number of intermediate variants of prototypes and reducing the complexity of design works.
The development of integrated systems to monitor main gas pipelines, namely laser, terrestrial and mobile (small-scale aviation) measurements is topical. This should facilitate the development and implementation of ground-based monitoring tools, and as they develop a gradual decline of remote sensing, including satellite monitoring systems.
In the future, there are plans to conduct research aimed at establishing a monitoring system based on wireless sensor networks and their integration with mobile aviation laser system monitoring.
