上海地铁某运营线车地通信参数的优化配置

Optimization of Parameter Configurations in Train/Wayside Communication System of Shanghai Metro

利用健壮性设计(Robust Design)方法,对上海地铁某运营线车地通信系统的参数进行优化配置,从而降低车地通信系统对噪声信号的敏感性,增强车地通信信号的质量。分析了地铁车站的信号干扰源,并对车地通信系统的控制参数进行合理配置。通过现场试验,该配置方案可减少车地通信系统的维护工作量,一定程度上降低了地铁运营成本,同时还可提高工作效率。

The parameter optimization of the train/wayside communication system in Shanghai metro is elaborated, which aims at reducing the sensitivity of the system for noise signals and enhancing the signal quality of the system. In this paper, the sources of noise signals at corresponding metro stations are analyzed, and train/wayside communica- tion parameter configurations are optimized. Through field tests, this configuration scheme is verified to be able to reduce the maintenance of the system and enhance the operational efficiency, and thus will reduce the operational cost of metro.
