Abstract: The FAO signaling system has further improved the safety and efficiency of the urban rail transit operation system and has a higher level of automation. However, compared with traditional CBTC signaling system, FAO signaling system has more requirements for acquisition and linkage with external interfaces. Based on the characteristics of FAO system, this paper proposes a test scheme of interfaces between FAO signaling system and external systems to verify the linkage function, engineering data and interface protocol related to external interfaces, so as to provide guarantee for the opening of FAO line.

摘要： FAO系统进一步提升城市轨道交通运行系统的安全与效率，具有更高的自动化水平，但FAO信号系统相较于传统CBTC信号系统与外部接口有更多的采集和联动需求。针对FAO系统特点，提出一种FAO信号系统与外部接口的测试方案，对信号系统涉及外部接口相关的联动功能、工程数据、接口协议进行验证，为FAO线路的开通提供保障。
