摘要：
本发明公开了一种基于北斗导航卫星姿态测量的电力铁塔变形监测系统，其特征是包括：北斗卫星信号接收模块、北斗卫星信号解析模块、计算处理模块、3/4G无线通信模块和电源模块；一种基于北斗导航卫星姿态测量的电力铁塔变形监测方法，其特征是按如下步骤进行：首先接收并解析北斗导航卫星的实时射频载波信号，然后建立铁塔上基线L的姿态角数学模型，最后利用近似梯度逼近算法求解该姿态角数学模型，获得基线L的姿态角。本发明引入近似梯度逼近算法求解多约束条件的姿态角数学模型，算法的可实现性更强，测量地姿态角的精准度更高，具有广阔的应用前景。

The invention discloses a Beidou navigation satellite attitude measurement-based electric iron tower deformation monitoring system. The system is characterized by comprising a Beidou satellite signal receiving module, a Beidou satellite signal resolution module, a calculation processing module, a 3/4G wireless communication module and a power supply module. A Beidou navigation satellite attitude measurement-based electric iron tower deformation monitoring method is characterized by comprising the following steps: firstly, receiving and resolving a real-time radio frequency carrier signal of a Beidou navigation satellite; then, establishing an attitude angle mathematic model of a base line L on the iron tower; and finally solving the attitude angle mathematic model by utilizing an approximate gradient approximation algorithm to obtain the attitude angle of the base line L. The attitude angle mathematic model with multiple constraint conditions can be solved by introducing the approximate gradient approximation algorithm, has strong algorithm realizability and high attitude angle accuracy for measurement place, and has a wide application prospect.
