Research on WSN Location of Intelligent Substation Personnel Based on Improved 3DL Algorithm
In order to improve the positioning accuracy of personnel wireless sensor network(WSN)in intelligent substation,a positioning method based on improved 3DL algorithm is proposed.By compensating the node ranging error and positioning er-ror of 3DL algorithm,the node ranging error and positioning error of 3DL algorithm are reduced,and the improvement of 3DL algorithm is realized.Applying the improved 3DL algorithm to the WSN of intelligent substation personnel can effectively im-prove the positioning accuracy of the WSN of intelligent substation personnel.Compared with the improved 3DL algorithm and the traditional maximum likelihood estimation algorithm,the proposed method has higher positioning accuracy and coverage,which can reduce the impact of the cumulative error of the location node coordinate calculation,and is more suitable for the WSN positioning of intelligent substation personnel in the non-line-of-sight environment.
