摘要
乘客信息系统(PIS)的播控器控制1个区域(如上行,下行站台)的显示回路,当管理该区域的1台播控器/工控机发生故障,则该回路的所有PIS显示屏将失去导向功能,引起乘客投诉。因此PIS系统的可靠性成为轨道交通运营服务的一个重要内容。研究探讨一个最新的技术方案,在不增加投资成本的前提下,大幅度提升PIS播控器的可靠性和稳定性,并在上海地铁5号线PIS系统维护改造中成功应用。
In a metro PIS system, a media player usually controls a display platform（up or down side）. However if the media player is broken, all the PIS screens in the platform will be out of service, which may cause passengers＇ complaints. How to improve the reliability of PIS system becomes an important subject for rail transit. The paper introduce a new solution to improve greatly the reliability and stability of the media player of the PIS system under the condition without increasing the hardware cost, and the solution has been successfully applied in shanghai metro line 5 project.
