摘　　要：在传统北斗卫星定位技术的基础上,结合无线传感器测距技术,提出了一种基于北斗定位的电力传感器定位方法,解决了电缆沟内电力传感器定位问题。该方法以北斗系统定位到的电力盖板终端为参考节点,通过引入转换矩阵和补偿矩阵,建立北斗卫星与电缆沟内传感器的位置关系,使用最小二乘法直接解算电缆沟内电力传感器位置坐标。仿真结果表明,所提出的基于北斗定位的联合定位算法可以准确地定位到电缆沟内电力传感器的位置坐标。On the basis of the traditional Beidou satellite positioning technology,combined with the wireless sensor ranging technology,a power sensor positioning method based on Beidou positioning is proposed in this paper,which solves the problem of power sensor positioning in cable trenches.This method takes the power cover terminal located by the Beidou system as the reference node,establishes the positional relationship between the Beidou satellite and the sensor in the cable trench by introducing the transformation matrix and the compensation matrix,and directly calculates the position coordinates of the power sensor in the cable trench by using the least square method.The simulation results show that the proposed joint positioning algorithm based on Beidou positioning can accurately locate the position coordinates of the power sensor in the cable trench.
