摘要:
［目的］为实现苏州轨道交通11号线与3号线贯通运营，需根据线路特点和运营需求定制专属的信号系统改造技术方案，以实现“一线一案”的技术目标。［方法］分析了城市轨道交通信号系统无人驾驶制式升级改造的技术关键点，结合苏州轨道交通11号线与3号线贯通运营信号系统改造方案，从车站改造、控制中心贯通、网络兼容等方面阐述了信号系统改造过程中的技术难点和创新点。［结果及结论］苏州轨道交通3号线为国内首条由GOA2(半自动化列车运行)升级为GOA4(无人干预列车运行)的线路，信号系统改造完成后，3号线运营更安全、更高效、更智能，同时实现了11号线与3号线两线信号系统的全面兼容和无扰贯通。
Abstracts:
［Objective］To enable the through train operation between Suzhou Rail Transit Line 11 and Line 3, a customized signaling system upgrade solution is required based on the unique characteristics and operational demands of the lines, aiming to achieve the technical goals of 'one line, one plan'. ［Method］ The key technical points in upgrading the urban rail transit signaling system to driverless operation mode are analyzed. The signaling system upgrade plan for Suzhou Rail Transit Line 11 and Line 3 through train operation is examined, with a focus on the technical challenges and innovations in station renovation, control center integration, and network compatibility. ［Result & Conclusion］ Suzhou Rail Transit Line 3 is the first in China to upgrade from GOA2 (semi-automated train operation) to GOA4 (fully automated train operation). After the signaling system upgrade is completed, Line 3 operates more safely, efficiently, and intelligently, while ensuring full compatibility and seamless integration between the signaling systems of Line 11 and Line 3.
