Large-span bridge girder hoisting system based on Beidou positioning
The invention discloses a large-span bridge girder hoisting system and method based on Beidou positioning. The large-span bridge girder hoisting system comprises a three-dimensional precise positioning system and an automatic hoisting control system. The three-dimensional precise positioning system comprises a Beidou base station, a Beidou positioning terminal, a differential service system and a data center. The Beidou base station is used for continuously tracking and observing Beidou satellite signals and providing carrier phase difference data for positioning; the Beidou positioning terminal is mounted on a sports car and a hoisting point and is used for acquiring positioning data of the sports car and the hoisting point; and the automatic hoisting control system processes the data of the data center of the three-dimensional precise positioning system, and controls the sports car and the hoisting point to run towards the target. The system has the advantages that the problems that in the prior art, the measurement precision is not accurate due to elastic deformation and position change of a traction cable, the control precision is not high due to the fact that an interphone is matched with manual operation, and the parking precision and the hoisting precision of the sports car are affected are solved, and automatic control and accurate fixed-point parking of the sports car in the hoisting process are achieved, and the hoisting height of the main beam is accurately and stably controlled.
一种基于北斗定位的大跨度桥梁主梁吊装系统及方法，包括三维精准定位系统、吊装自动控制系统；三维精准定位系统包括北斗基准站、北斗定位终端、差分服务系统和数据中心；北斗基准站以连续跟踪观测北斗卫星信号并提供定位的载波相位差分数据；北斗定位终端安装于跑车上和吊点上，获取对跑车和吊点的定位数据；吊装自动控制系统根据所述三维精准定位系统的数据中心的数据并进行处理，控制跑车和吊点向目标运行。其优点是解决了现有技术因牵引索的弹性变形、位置变化造成测量精度不准确、通过对讲机配合人工操作造成控制精度不高，从而影响跑车停放精度和吊装精度的问题，吊装过程跑车的自动控制和精准定点停放，主梁吊装高度的准确、平稳控制。
