摘要
介绍了一种基于DSP和线阵CCD技术的电力机车接触网瞬时拉出值的高速测量系统的总体柜架,阐述了其数字图像信号的实时处理与传输,描述了提高可靠性及抗干扰的措施,在高速接触网的检测中,该系统能快速检测接触网的瞬时拉出值,又能记录接触网的杆位及杆号,测量分辨率可达1mm。
It is presented the general frame of a high-speed measuri ng system for transient contact line stagger value of electric locomotive based on DSP and li near CCD technology. Real-time treatment and transmission of the digital image signal is explained. Measures are illustrated to improve reliability and anti-interference performance. In the detection of high-speed contact line, the system could detects quickly the transient stagger value, and records the position and No. of the contact line, with a measuring resolution of 1 mm.
