随着铁路运行速度不断提高和道路机动车辆数量猛增,铁路道口已是当前交通安全的关键部位,也是铁路安全的薄弱环节。针对目前国内的道口安全问题,设计了一套基于DSP和CPLD的铁路道口图像监控系统。在介绍系统组成和工作原理的基础上,给出了硬件和软件设计方案件,从而为我国铁路行业安全保证提供一个低成本和高可靠性的解决方案。
With the continuous improvement of the railway speed and the rapid increase of the number of road vehicles, the railway crossing has become a key part of current traffic safety and is also a weak link in railway safety. In view of the current domestic crossing safety, a set of railway crossing image monitoring system based on DSP and CPLD is designed. On the basis of introduction of the system composition and working principle, the hardware and software design programs are given, so as to provide a low cost and high reliability solution for the railway industry in our country.
