摘要
地铁线路建成后,由于机电设备监控项目子系统多、跨子系统联动功能复杂、调试时间不充裕、多专业协调难度大等原因,往往难以按时开通。即使线路已经运营,仍会有部分功能需陆续测试和验收。研究发现,造成这种现状的主要原因是传统的机电设备监控系统采用了分层分布式现场总线网络和控制策略集中的控制方式。可以通过其系统结构的优化来解决上述问题。
After the construction of rail transit lines, trains are still hard to launch on time because the electric power system monitoring has many variant with sophisticated functional con- nections, insufficient debug time and difficult coordination of o- verall functional portions. Even when one subway line has been put into service, a series of testing and acceptance will still be needed for some operational functions. After a mass research, the fundamental cause of this situationis detected, because the traditional electric power monitoring system adopted tiered dis- tribution network on spot and the centralized control manner of bus network. But, an optimization of the monitoring struc- ture can solve these problems effectively.
