摘要
从移动闭塞的功能出发,阐述了广州地铁3号线ATC系统的列车定位技术。3号线信号系统以交叉感应环线为车-地通信介质,列车定位方面采用交叉感应环线进行粗略定位,采用车载测速发电机进行精确定位,同时还采用接近传感器进行站台辅助定位。此外还对定位技术中的抗干扰屏蔽、轮径补偿和空转及打滑监测等作了阐述。
This article mainly describes the theory of train positioning in the ATC system for Guangzhou Metro Line 3. The signaling system of Guangzhou Metro Line 3 uses inductive loop cables as the commu- nication medium between vehicle and wayside equipment. Crossover inductive loop cables on the guide- way are used for coarse positioning and onboard tachometers are used for fine positioning while approac- hing sensors aligned at a platform are used to provide auxiliary positioning confirmation. Also, this article discusses anti - interference screening, compensation for wheel diameter deviation, monitoring of idle running and sliding.
