对铁路接触网激光测量系统的探讨

Discussion on the Railway Catenary Laser Measurement System

本文叙述了测量系统的组成和测量原理,详细介绍了系统的数学模型和误差分析,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。与以往的测量方式相比,此测量系统可进行方位向旋转,从而对铁路接触网的测量参数更全、速度更快,测量精度可达±5mm。

This paper describes the structure and measuring principle of measurement system, introduces the mathematical model and error analysis system, ty was analyzed and evaluated. Compared with and the main parameters of railway catenary measurement uncertain- the measurement method in the past, this measurement system can be the azimuth rotation, to measure the parameters of catenary of bigger, faster, measurement accuracy of ± 5 mm.
