Мониторинг уровневого режима открытой мелиоративной сети необходим не только для ее безопасного функционирования, но и для определения объема водоподачи в измерительных створах, оборудованных средствами водоучета. Автоматический мониторинг уровней на открытой мелиоративной сети наиболее проблематичен. На старых оросительных системах используются устаревшие средства измерений, внедрение цифровых технологий ограничивается высокой стоимостью оборудования и сложностью подвода электроэнергии к удаленным створам. Целью исследований была разработка автоматизированного цифрового комплекса для мониторинга уровня воды на открытой мелиоративной сети с питанием от возобновляемого источника энергии и испытание экспериментального образца в условиях действующей оросительной системы.Методы. При выборе конструктивных элементов и разработке программного кода выполнен анализ условий эксплуатации, диапазонов и требуемой точности измерений; использованы методы теории программирования логических контроллеров, декомпозиции и формализации алгоритмов, структурного программирования. При испытаниях опытного образца использованы методы теории планирования эксперимента, математической статистики и теории ошибок.Результаты. Экспериментальный образец цифрового измерительного комплекса в автоматическом режиме производит измерения температуры воздуха, атмосферного давления и расстояния до уровня свободной поверхности воды, производит их запись в память устройства и/или передачу на удаленный сервер. Для работы комплекса требуется постоянное напряжение 5 В, питание возможно от солнечной батареи и/или от аккумулятора. Испытания автоматического комплекса в водоеме при отсутствии выраженного течения и в канале с максимальной скоростью течения порядка 2,6 м/с продемонстрировали удовлетворительную точность измерений.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Monitoring of the level regime of an reclamation network is necessary not only for its safe operation, but also for determining the volume of water supply in measuring points equipped with water accounting facilities. The automatic monitoring of levels in an open reclamation network is the most problematic. Old irrigation systems use outdated measuring instruments, the introduction of digital technologies is limited by the high cost of equipment and the complexity of supplying electricity to remote sites. The aim of the research was to develop an automated digital complex for monitoring the water level in an open reclamation network powered by a renewable energy source and to test an experimental sample under the conditions of an existing irrigation system.Methods. When choosing structural elements and developing a program code, an analysis of operating conditions, ranges and required measurement accuracy was carried out; methods of the theory of programming logic controllers, decomposition and formalization of algorithms, structural programming were used. When testing a prototype, methods of the theory of experiment planning, mathematical statistics and the theory of errors were used.Results. An experimental sample of a digital measuring complex automatically measures air temperature, atmospheric pressure and distance to the level of the free surface of water, records it in the device's memory and/or transfers it to a remote server. The operation of the complex requires a constant voltage of 5 V, it can be powered by a solar energy and/or a battery. Tests of the automatic complex in a reservoir in the absence of a pronounced current and in a channel with a maximum flow velocity of about 2.6 m/s demonstrated satisfactory measurement accuracy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мелиорация</kwd><kwd>водоснабжение</kwd><kwd>уровень воды</kwd><kwd>контроль</kwd><kwd>автоматическое измерение</kwd><kwd>автоматизация</kwd><kwd>датчики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>melioration</kwd><kwd>water supply</kwd><kwd>water level</kwd><kwd>control</kwd><kwd>automatic measurement</kwd><kwd>automation</kwd><kwd>sensors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при реализации Программы развития Университета в рамках программы стратегического академического лидерства «Приоритет-2030».</funding-statement><funding-statement xml:lang="en">The research was carried out during the implementation of the University Development Program within the framework of the program of strategic academic leadership «Priority-2030».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Манжина С.А., Медведева Л.Н.
