摘要
为满足高速铁路接触网检测系统动态数据实时性的要求,开发了基于嵌入式技术的动态数据采集系统。提出的方法是在原有的非接触式CCD摄像头接触网检测系统中应用嵌入式系统采集动态图像,在ARM最小系统板的基础上加外围芯片和接口,再移植嵌入式Linux操作系统完成图像采集,进而为下一步的图像处理和传输打下基础,最终完成接触网各几何参数的检测。试验室的系统测试表明,系统可以很好的完成动态图像的采集,满足实时性要求。
In order to meet the real-time of dynamic data in the High-speed Railway contact system detection,the dynamic data collection system is developed based on the embedded technology.The embedded system is used in the existing noncontact CCD cameras to collect dynamic images,adding peripheral chips and external interface in the smallest ARM board,porting Linux operating system to finish the collection,which is the basis of images processing and transmission,and eventually completes the detection of the contact system.Lab teat indicates that the system could complete the collection of dynamic images,meeting the real-time requirement.
