【 摘 要 】

The process of end-to-end digital design of the closed control system for exhaust gas neutralization of cars proposed by the authors is considered. Known catalysts with heating, but without heating control are not effective enough to neutralize harmful exhaust gases. The system includes measurement means of gas concentration, control unit and standard units of the vehicle catalysis exhaust system, communication devices, GPS/GLONASS as elements of this control system. The stages of end-to-end digital system design from digital modeling of functions, schematic, design solutions oriented on selected production technologies are considered. Full or partial digital design of technological and production processes is provided. The principal novelty is the use of catalyst controlled heating, as well as the creation of assign vehicle units of the system for serial production. A computer program has been developed that simulates the stages of digital electronics production for environmental monitoring systems. The computer program contains elements of the cyber physical systems concept. The computer program is designed to ensure the quality of design and production efficiency. The knowledge base was built as ontological approach for supporting and updating information about the system with the ability to extract knowledge at the request of users is proposed. The input information for filling the knowledge base is formed on the basis of conceptual and constructive knowledge, as well as databases containing information about the system elements. The description of the knowledge base, the results of the development, possible ways of development are given.
