摘要
针对电力铁塔的实时高精度姿态监测问题,对GPS基线测姿原理进行研究,设计和开发了GPS测姿仪,在3D3S软件中建立电力铁塔的三维模型并对其施加极端荷载,通过分析仿真结果,得到铁塔姿态角的合理变化范围及确定测姿仪安装位置,并制定了铁塔安全状态判定策略,提出了基于GPS测姿仪的电力铁塔姿态监测方案。搭建铁塔场景对测姿仪的测姿精度进行实测实验,实验结果表明:GPS测姿仪的测姿精度达到0.1°,可满足电力铁塔监测要求,稳定性好,能够实现高精度实时监测。
Aiming at the problem of real-time and high precision monitoring for power tower attitude,the attitude measurement theory of GPS baseline is studied in this paper,and a three-dimensional model of the power tower is built in the 3 D3 S software. Then extreme loads is applied to the model,and the simulation results can be used to obtain the reasonable range of the attitude angle and determine the installation position of the attitude measuring device. Moreover,the safety status determination strategy is worked out,and the attitude monitoring scheme of power tower based on GPS attitude measuring device is proposed. The experimental result shows that the attitude accuracy reaches 0. 1 degrees with a good performance of stability,which meets the requirements of power tower monitoring and realizes realtime monitoring with good precision.
