Design of an Ultrasonic Telemetry Information Transmitter for the Downhole-Wellhead Communication Channel

2022 · CHAPTER · en

The problem of creating an energy-efficient and compact downhole telemetry system in the ultrasonic operating frequency band is relevant but currently not solved. The investigations are aimed at finding possibilities to transmission of telemetric information that provide the better noise immunity and data transfer rate. An ultrasonic transmitter designed as part of the study of the ultrasonic communication channel is presented. A MA40S4S transmitter was used to convert the acoustic signal into an electrical one. The signals are transmitted at a frequency of 40 kHz. The “Manchester-II” coding system is used, implemented in the PIC18F2455 microcontroller. The paper presents the results of testing equipment using amplitude and frequency modulation. It is shown that amplitude of the transmitted signal is significantly reduced when frequency modulation is used due to the narrow frequency band of the receiver and transmitter. The paper presents the electrical circuit of the transmitter with a detailed description. It was found that an AC voltage occurs between the transmitted data packets. This problem was solved using a key. The electrical circuit is powered by 12 V batteries, because it is no 220 V power supply in the field.

Crossbar Switch Arbitration with Traffic Control for NoC

2022 · CHAPTER · en

Abstract—NoC is a network of computing cores (IP cores) for processing information and routers for transferring data between IP cores. NoC has a lot of applications: it is used in communications, transport, in the Internet of Things ecosystems and the Internet of Drones. Routers are used to efficiently exchange messages between IP cores. One of the important functions of a router is arbitration. In this paper, we review the main arbitrage methods: Fixed Priority Arbitrage (FPA), Matrix Arbitrage, Round Robin Arbitrage (RRA), and some of its modifications for crossbar switching systems. We propose a conceptual framework for traffic control of NoC routers using arbitration techniques. Fairness as an important property of an arbitrator is considered. Different approaches have been proposed and some have been justified. The comparison of the simulated data shows that the results are in good agreement with both available experimental data and proposed models in the literature.

Решение проблем редукции данных в автоматизированных системах коммерческого учёта потребления тепловой энергии для создания робастной модели

2021 · ARTICLE · ru

Одной из тенденций развития современного городского хозяйства является энергосбережение. В жилых домах, потребляется более 40 % энергоресурсов, а большая часть расходуемой энергии используется для отопления. Актуальной проблемой является повышение энергоэффективности жилых многоэтажных зданий, что связано с уменьшением теплопотерь и организацией регулирования подачи тепловой энергии в зависимости от погодных условий. Построение модели такого регулирования представляет коммерческий и академический интерес, но проблемная ситуация в моделировании зачастую связана с качественным сбором данных: они содержат ошибки, данные не стратифицируются с учётом схемы теплоснабжения, а объём ежесуточных данных не позволяет создать модель минимального порядка, которая должна быть робастной, но правильно отражать динамику изменения теплопотребления от температуры наружного воздуха. В статье предложены подходы к преобразованию данных, которые могут быть использованы для построения робастной модели теплопотребления минимального порядка. Они основаны на спектральном анализе и гистограммных оценках статистического распределения данных, взятых за большой период времени. Найден способ сравнения домов с разными схемами теплопотребления, рассчитано среднее значение потребления ГВС и показано, что возможна стратификация данных при совместном учёте горячего водоснабжения и отопления. В результате спектрального анализа рядов теплопотребления обнаружено, что погодозависимость в основном определяется первыми десяти низкочастотными гармоническими составляющими рядов теплопотребления. Предложен алгоритм редукции рядов, что делает возможным построение робастной модели потребления тепла в размерах всего города.

Features of the Implementation of the Extremal Filtration Method in the Distributed Optic-Fiber Temperature Sensor

2021 · CHAPTER · en

The signal processing method based on extremal filtration in low signal-to-noise ratio conditions was proposed. The extremal filtration is similar to the empirical mode decomposition (EMD) method, but complex mathematical calculations are absent that is the main advantage. Using it in real measuring devices significantly increases the speed rate. The extremal filtration process is an algorithm that involves sequentially repeating until an optimal result. The disadvantage of this method is decreasing the spatial resolution since every iteration due to a reduction in the number of samples. It is an especially negative fact in areas of sharp signal change. This paper demonstrates how to solve this problem using linear interpolation and to improve the result obtained by simple extremal filtration.

The XV Siberian Conference on Control and Communications (SIBCON), the flagship conference of the joint Tomsk IEEE Chapter was held in Kazan, Russia in May. This series started in 1995 to focus on the convergence of communications and control technologies. In particular, the discussions highlight the practical problems related to this field. Previous meetings took place in Tomsk, Krasnoyarsk, Astana, and Moscow. The conference comprised a hundred presentations divided into three tracks. On the first day, sessions deal with various aspects of the communications, such as QoS, Signal Processing, Wireless technologies, Antennas and Propagation, additional topics including network control and satellite communications. The papers of the second day covered control and robotics. The final day was related to technical excursions in the frameworks of the conference and social program. Plenary sessions were organized to give insight into new developments in the theory and practice of advanced control and communications. Keynote speaker, Professor of the Radio Telecommunication Systems department of the Kazan National Research Technical University Yuri Choni talked about the engineering approach to antenna synthesis and its role in the research in the field of communication via a geostationary satellite. He proposed an extremely fast algorithm for antenna synthesis based on some robust engineering assumptions. Professor Max Talanov from Kazan Federal University discussed brain-computer interface (BCI) technologies overview in the context of integration with robotic and biological systems starting from classical perceptron till current breaking through technologies of BCI could change the scientific outlook of the field. He references a lot of interesting projects dedicated to BCI. The attention of many participants was paid to an emerging topic "Robotics and information systems for disaster management" which was addressed by the General Chair of SIBCON, Prof. of Institute for Information Technologies and Intelligent Systems (Kazan Federal University) Evgeni Magid in the report and at the allied invited session. Another point of interest was the sessions on the distributed temperature sensors, the borehole telemetry transfer system, with application to MWD-LWD geophysical systems - a topic independently initiated and widely studied by the Tomsk Chapter members. The invited lectures were very different and presented a wide range of achievements and perspectives in communications, control, and its applications. In the session on control, various problems related to analysis, identification, and control of complex oscillatory dynamical systems, with emphasis on both theory and applications, were considered. The conference allowed us to bring together and to cross-fertilize ideas from these fields which have many similarities. A number of the papers addressed the problems of analysis of complex behavior in physical systems. Significant attention was paid to the analysis and design of neural networks, robotics, unmanned aerial vehicles, and AI. Participants presented the most recent researches and shared ideas. We are proud that SIBCON is able to attract really outstanding people, and the connections in the academic community are really strong. It should be noted the balance of ideas of science and practice, a wide range of areas for applications of information technology in communications. Of course, a rare combination of a strict timetable for plenary sessions, an unobtrusive rhythm of speeches and discussions in sessions, and an almost home atmosphere is the merit of the Organizing Committee. Kazan, the third Russian city, witnessed many exciting events in history and still plays a very important role in its scientific and cultural life. The conference was held in the Kazan Federal University located in the historical part of the city. The participants had the opportunity to enjoy the historical sites, as well as the beauties of this city, including the masterpieces of the Kazan Kremlin, palaces, and charming districts. Recent months have had a negative effect because all researching work is based on the co-authors' communication, but researches in one location have lowered productivity. Time is especially valuable for scientists. Now scientists are in some euphoria because we can participate in a large number of conferences at once. However, there is no substitute for human communication based on a real exchange of energy and emotions. Now communication and relationships have changed. Formats of professional events have become more efficient and ergonomic. The academic conferences will be modernized like everything in the world. Offline events already have developed a certain culture, traditions, become a part of the scientific community life. Therefore, we need to continually invent ways of comfortable discussions. In this SIBCON we are succeeded. Thanks to the face-to-face format and only to a small extent remotely, we could keep the unique atmosphere of the in-person conference and the luxury of connection between professionals. Of course, in the future, people will try to combine formats, because the social aspect is extremely important. We have been parted with the hope of future meetings, counting on understanding and partnership in solving common problems.

Modeling the Processing of Non-Poissonian IIoT Traffic by Intra-Chip Routers of Network Data Processing Devices

2021 · CHAPTER · en

The ecosystem of the Internet of Things (IoT) continues to grow at the present time and covers more and more areas. One of these areas is the Industrial Internet of Things (IIoT), which integrates sensors and actuators, business applications, open web applications, multimedia security systems, positioning and tracking systems. Each of these components creates its own data stream and has its own parameters of the probability distribution when transmitting information packets. One such distribution, specific to the Trumpf TruPrint 1000 IIoT system, is the beta distribution. In our article, we described the results of a study of the processing of such a data flow by an agent model of a 5 × 5 NoC switch fabric. The concepts of modern telecommunication networks (5G / 6G) imply the processing of "small" data in the place of their origin, not excluding the centralized processing of big data. This process, which involves the transmission, distribution and processing of data, involves a large number of devices: routers, multiprocessor systems, multi-core systems, etc. We assumed that the data stream is processed by a device with a network structure, such as NoC, and goes to its built-in router. We conducted a study of how the average queues of a 5 × 5 router change with changes in the parameters of a data stream that has a beta distribution.
