Design Of Subway Integrated Monitoring System Based On Cloud Architecture

In recent years, with the rapid growth of the urban population, the urban traffic pressure is bigger and bigger, therefore, many cities are implementing the scheme that vigorously develop the subway to ease the urban traffic pressure. The metro Integrated Supervisory Control System (ISCS) subsequently emerged has also obtained the very good development, and a more stable and intelligent metro ISCS is pursued by the metro construction enterprise.This paper came from the integration engineering of Shenzhen Metro Line 7 integrated supervisory control demonstration system, at the same time, it improves its performance and inherits its traditional advantages. This system adopts the technical proposal combining the cloud technique with the configuration technique, and uses the virtualization technology to achieve long-distance control. Multiple subsystems such as PSCADA, FAS, BAS, PIS, etc. are integrated into a comprehensive management platform, which are managed and monitored by this platform. On the other hand, it transmits the data information into cloud resource pool to stat and analyze, the cloud technology introduced has not only improved the intelligent degree of subway integrated monitoring system, but also is conducive to improve the controllability of the system, and can provide a better protection for safe operation of metro system.This article has introduced the concrete steps using industrial control configuration software IndasIBMS to design the metro ISCS, outlined the solution of build cloud platform, tested metro ISCS based on cloud technology and analyzed its performance, and given a reasonable solution for the problems appeared in the process. Finally, it made some outlooks on future development of metro ISCS.
