上海轨道交通2号线车辆PIS报站广播功能升级与优化

Upgrade and Optimization of Vehicle PIS Station Broadcasting Function of Shanghai Rail Transit Line 2

上海轨道交通2号线信号系统升级改造为CBTC(基于通信的列车控制)系统后,同时考虑实现DTO(有人值守的全自动运行)功能。为提升运营服务质量,需升级与优化PIS(乘客信息系统)报站广播功能。介绍了CBTC系统和PIS的基本功能;介绍了2号线不同车型列车PIS全自动报站广播功能的实现方式,以及PIS半自动报站广播功能优化后的报站模式切换逻辑。PIS报站广播功能升级与优化后,降低了人工操作失误造成的无广播或报错站的概率,规避了站间停车时提前广播的问题及报站不准确的问题,提高了运营服务质量。

After the signaling system of Shanghai Rail Transit Line 2 is upgraded to CBTC(communication-based train control)system,DTO(unattended train operation)function is considered for implementation.To improve operation and service quality,the PIS(passenger information system)station broadcasting function needs to be upgraded and optimized.The basic functions of CBTC system and PIS are introduced,and the implementation methods of fully automatic station broadcasting for different train models on Line 2 and the broadcasting mode switching logic after PIS semi-automatic broadcasting function optimization are introduced.The optimized PIS station broadcasting function reduces the probability of manual errors resulting in no broadcasting or incorrect station information.It also addresses issues related to premature broadcasting during station stops and inaccurate station broadcasting,thereby improving the operation service quality.
