Abstract: In response to the problems of incomplete alarm mechanism and unclear fault location in the traditional operation and maintenance (O&M) mode of the passenger service and production control platform (referred to as the management and control platform), this paper designed and developed an integrated monitoring and alarming system for management and control platform (referred to as the monitoring and alarming system). The paper elaborated on the architecture design, functional design, key technologies, and practical application of the system. The application situation shows that the monitoring and alarming system improves the basic process of traditional operation and maintenance, can timely discover potential anomalies, predict the evolution trend of faults, enhance the ability of business data analysis, processing, and mining of the control platform, and overall improve the digitalization and intelligence level of the control platform.
