基于高精度北斗定位的桥梁形变监测

在简单介绍北斗高精度卫星接收机的特点、工作原理、数据格式及数据处理方法的基础上，根据桥梁，特别是高速火车移动荷载作用下铁路桥具有实时振动和瞬时形变的特点，提出了桥梁形变监控的组网方式通信手段、数据输出格式、数据采样频次等关键技术的针对性处理方法，以满足桥梁形变监控的要求。

Bridge Deformation Monitoring Based on High Precision Beidou Positioning

The characteristics of Beidou high precision satellite receiver, working principle, data format and data processing method are introduced in this paper. In view of the bridge, especially the high-speed train moving load under the action of railway bridge has the real- time vibration and instantaneous deformation characteristic, it proposes targeted treatment towards the key techniques such as the bridge deformation monitoring network mode of means of communication, data output format and sampling frequency of data processing meth ods, in order to meet the requirements of bridge deformation monitoring.
