Research on Safety Monitoring of Dynamic Geometric Parameters of Catenary Based on Laser Scanning Radar

针对高速铁路动车组,开发了基于激光扫描雷达的接触网动态几何参数监测系统。运用最小二乘数据拟合方法提高检测结果精度。针对接触网的薄弱环节,如线岔、锚段关节、分相等部位,采用基于Kalman滤波跟踪方法,实现不同接触线的识别。该监测系统能够准确检测接触网动态几何参数,有效保证行车安全。

Aiming at the normal operation of high-speed railway EMUs,dynamic geometric parameters monitoring system based on laser scanning radar is developed.The least squares data fitting method is applied to improve the accuracy of detection results.Aiming at the weak links of the catenary,such as the overhead crossing,the overlap and the neutral section parts,the Kalman filter tracking method is proposed to identify different contact lines.The monitoring system can accurately detect the dynamic geometric parameters of the catenary,and effectively improve driving safety.
