LCD 列车动态地图系统主控单元研究与应用

摘要

LCD train dynamic map system ,as the result of train passenger information system′s development ,makes PIS more responsive to the operating mode centered on passengers .Firstly the framework of LCD train dynamic map system is designed , and then the implementation of this system′s kernel module is focused on ,w hich is dynamic map system′s main control unit .T his module controls all of dynamic map scenes switching and manages all the elements in these scenes according to messages from train controller via serial communication module . This system has been used in a certain metro of Shenzhen .%　　LCD列车动态地图系统是列车乘客信息系统（PIS ）不断发展的必然产物，它使PIS更加适应以乘客为中心的运营模式要求。首先设计了LCD列车动态地图系统框架，然后重点介绍了该系统核心模块———动态地图系统主控单元———的实现。该模块通过串口通信模块接收列车主控的消息，控制具体动态地图场景的切换和具体元素的管理。该系统已成功应用于深圳某地铁。
