摘要
主要介绍电网高压线接触网激光测量仪的研制,它利用CCD作为成像器件来观察目标,利用电子分划来代替激光点,从而克服了现有测量仪的一些缺点。激光测量仪采用0.635μm波长的激光作测量激光来实现测距;高性能的CCD作为成像接收器件避免了传统的靠人眼来瞄准测量的缺点,解决了人眼的疲劳问题。详细叙述了测量系统的组成和测量原理,详细分析了系统的测量数学模型和测量误差,并对铁路接触网主要测量参数的不确定度进行了分析和评定。
A kind of laser measurement system for geometrical parameters of power lines with CCD as imaging device to observe the targets and electronics division instead of laser spot is introduced in this paper, which overcomes the shortcomings of existing measuring systems. 0.635 μm wavelength laser is used to realize distance measurement and high-performance CCD is as image receiving device of the system instead of human eyes so as to avoid eyestrain. The architecture and measurement principle of the system are described, and the mathematics model and the error margin of the system are analyzed in detail. The indetermination degrees of main parameters of the system are analyzed and judged.
