摘要
发车指示器主要完成发车时间及相关发车控制命令的显示,用于为列车司机提供离站时间、状态等信息,是地铁运营的重要辅助设备。发车指示器接收ATS系统的控制命令并将此信息显示在LED屏幕上,供列车司机行车参考。讨论一种基于μCOS嵌入式系统的发车指示器软硬件结构,及在城市轨道交通线路中的实际应用。
The departure indicator mainly indicates the departure time and the related departure control commands, and it is an important auxiliary equipment in underground operation for providing arrival time, status and other information for the train driver. The departure indicator receives control commands from ATS system and displays this information on the LED screen for reference by the train driver. The paper illustrates the hardware ＆ software structure of the departure indicator based on uCOS embedded system, and inroduces the practical application in urban rail transit lines.
