信息集成和数据库建设是地铁信息化的基础,地铁综合监控系统能够使信息有效整合,从而在系统内提供及时、准确、可靠信息,与有关部门进行信息共享和为领导决策提供支持。而不同子专业系统提供数据量大、协议不同,给服务器的性能达到瓶颈。为了实现综合监控与提高数据处理能力,在服务器与子专业系统间加入FEP(Front End Processor,前端处理器),使综合监控系统更加稳定、数据能力更强。为了使单台FEP在突发故障的情况下,综合监控系统仍能正常工作,配置两台FEP来实现冗余。
Information integration and database construction are the basis of subway informationization. The integrated subway monitoring system can effectively integrate information so as to provide timely, accurate and reliable information in the system, share information with relevant departments and provide support for decision-making of leaders. Different sub-professional system to provide a large amount of data, different protocols, to server performance bottlenecks. In order to achieve comprehensive monitoring and data processing capabilities, FEP (Front End Processor) is added between the server and the sub-professional system to make the comprehensive monitoring system more stable and data capable. In order to make a single FEP in the case of a sudden failure, the integrated monitoring system can still work properly, configure two FEP to achieve redundancy.
