Nowadays optical character recognition systems have a high level of dependence on the specific type of marking that is to be recognized, and therefore, the creation of a universal solution is an important and difficult task.

It is proposed a solution that recognizes symbolic information on the labeling of circuit breakers, which can be the basis for the development and description of systems serving for the automation of production, by transferring information read from the product during the production process. This system, by its example, describes the components of character recognition systems, and for direct use, it needs to be refined in accordance with the technical requirements and the specifics of the conditions in which it will be used.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>распознавание символьной информации</kwd><kwd>OCR</kwd><kwd>предобработка изображений</kwd><kwd>лингвистический анализ</kwd><kwd>автоматические выключатели</kwd><kwd>маркировка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>recognition of symbolic information</kwd><kwd>OCR</kwd><kwd>image preprocessing</kwd><kwd>linguistic analysis</kwd><kwd>circuit breakers</kwd><kwd>marking</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках темы № 0071-2019-0001 «Развитие теории и методов прикладной математики, нейросетевых технологий и систем управления процессами в задачах CADсистем, анализа визуальных данных, защиты информации и прогнозирования».</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the topic No. 0071-2019-0001 "Development of the theory and methods of applied mathematics, neural network technologies and process control systems in CAD systems, visual data analysis, information security and forecasting".</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">An efficient industrial system for vehicle tyre (tire) detection and text recognition using deep learning / W.
