摘要
针对轨道作业车在运行过程中车门可以手动开启、乘车人员不当触碰电气按钮等情况引发的安全隐患,设计了一种基于ARM CortexA-8嵌入式平台的轨道作业车车门控制与视频监控系统.阐述了该系统的硬件设计方案、软件架构、核心业务流程,以及车门控制、视频采集、视频显示等功能.通过电平转换、基于select/poll函数的多路设备状态监听、可视化监控等关键技术,实现轨道作业车车门的自动锁闭与开启,以及对乘车人员行为的实时监控.试用结果表明,该系统运行稳定,能够保障轨道作业车行车安全,具有一定的可用性.
Abstract
In response to the safety hazards caused by improper manual opening of doors and improper touching of electrical buttons by passengers during the operation of track operation car,this paper designed a car door control and video surveillance system for track operation car based on ARM Cortex-A-8 embedded platform,elaborated on the hardware design scheme,software architecture,core business processes,as well as functions such as door control,video capture,and video display of the system.Through key technologies such as electrical level conversion,multi-channel device status monitoring based on select/roll functions,and visual monitoring,the paper implemented automatic locking and opening of the doors of the track operation car,as well as real-time monitoring of passenger behavior.The trial results show that the system runs stably,can ensure the safety of track operation car,and has certain usability.
