The article analyzes the current regulatory framework for proof of safety, quality assurance, and confi rmation of the conformity of microprocessor-based railway automation and remote control systems in the EAEU. CENELEC standards are briefl y discussed. A brief overview is provided as regards measures to ensure the required level of safety of microprocessor-based railway automation and remote control systems from the point of view of quality management of development, safety management, and confi rmation of the proper functioning of microprocessor systems. The practice of confi rming the railway transport automated process control systems comply with standards in the form of a declaration of conformity per TR CU 003/2011 has been analyzed. It is concluded that there is a need to develop a regulatory framework to ensure regulated analysis and assessment of railway automation and remote control systems following the requirements of functional safety, as well as further development of standardization documents to regulate methods for assessing functional safety.

Abstract The article describes the main requirements of the software subsystems management development. Standard IEC 61508-3 provides an overview at all stages of the life cycle of all security systems, including E/E/PE of a security system from initial concept, design, and implementation to operation maintenance. In this paper we analyzed set out requirements for the drafting of a software architecture that is consistent with the hardware architecture while meeting specified requirements for software safety.
