Integrated Control Architecture of Station EM Equipment Based on Metro Networked Management Transformation

[Objective] Each technical subsystem in the EM (electromechanical) system of existing metro stations is based on mature systems in related industries, and applied to metro stations after adaptive modification. Despite meeting some functional requirements of the stations, these subsystems can hardly be integrated for lack of considering the operation characteristics and management needs of metro system, thus seriously hindering the development and improvement of management capabilities of related technical subsystems. Therefore, it is necessary to explore the integrated control architecture of station EM equipment and its evolution route from the bottom layer to improve the efficiency of management and control. [Method] The characteristics of metro networked operation and management, and the trends and requirements of networked management are introduced. An in-depth analysis of the problems existing in the control architecture of traditional station EM equipment, such as complex architecture, poor control functions, single function, poor linkage of subsystems, as well as difficulties in upgrading and transformation, corresponding breakthrough methods are proposed. Aiming at the centralized management and control of station EM equipment, an integrated design scheme for the above EM equipment intensive control is proposed with cloud, edge, and end as the core architecture, and some application design cases of this scheme in different innovative application scenarios are introduced. [Result & Conclusion] By introducing more powerful edge controllers, the control architecture of the EM equipment in existing metro stations is reshaped, forming an integrated control architecture of station EM equipment suitable for networked management，with cloud, edge, and end as its core architecture. This architecture can effectively improve the efficiency of centralized management and control of station EM equipment, enhance their functions, make up for the management blind areas, and at the same time achieve efficient linkage of terminal devices.
