广州地铁一号线应用了先进的电力监控系统 ,该系统由中央监控子系统和变电所综合自动化子系统组成。中央监控子系统由采用总线结构的SINECH1网络和 10BASE - 2网络构成 ,主操作站和备用操作站通过SINECH1网与远程通信接口柜交换数据 ;所有操作终端通过以太网与主操作站或备用操作站进行数据通信。变电所综合自动化子系统采用现场总线PROFIBUS ,其拓扑结构为主从式总线结构。变电所综合自动化子系统与中央监控子系统之间的通信采用点对点方式。该系统在使用中存在一些缺陷 ,需加以改进
Guangzhou Metro Line 1 application of advanced power monitoring system, which consists of central monitoring subsystem and substation automation subsystem. The central monitoring subsystem consists of SINECH1 network with bus structure and 10BASE - 2 network. The main operation station and standby operation station exchange data with remote communication interface cabinet via SINECH1 network. All operation terminals connect with main operation station or standby operation station via Ethernet Data communication. Substation automation integrated subsystem using field bus PROFIBUS, the main structure of the slave bus structure. The substation integrated automation subsystem and the central control subsystem uses the peer-to-peer communication system. The system in use there are some shortcomings, need to be improved
