接触网和轨道同步检测技术研究

将车体振动姿态检测数据引入到接触网检测系统，以消除由车体振动造成的接触网几何参数检测误差。采用接触网检测系统，通过对锚段、支柱、吊弦等关键零部件的识别，实现检测数据定位；，将定位数据与数据库中公里标称信息相关联，可消除轮径定位造成的累计误差，提高轨道检测数据定位精度。基于传统接触网和轨道检测技术，构建同步检测系统，实现接触网和轨道检测数据的共享，对于指导现场维护工作具有重要意义。

Research of Synchronous Detection Technology ofthe Catenary and Track

Introducingthe inspection data of body vibration attitude into the catenary detection systemcan effectively avoid the detecting error caused by the vibration of the detecting vehicles. The catenary detection by identifying of the key components of the pillars, droppers can realize the precise positioning of the detectingdata, and eliminate the accumulated error of positioning technology in the traditional track detection, positioning data in the database eliminated the accumulated error caused by wheel diameter location and improve the positioning accuracy of track inspection data. Therefore, building the synchronous detection system basing on the traditional catenary and track detection technology can achieve the detection data sharing and obtain accurate detectingparameters,the synchronization detection systemhas important significance for guiding field maintenance work.
