Design of Dynamic Accurate Positioning Platform for Inspection Personnel Distribution Station Based on Tracking Particle Filter Algorithm
The strong electromagnetic noise generated by the power grid has strong disturbance to the conventional positioning signal.In order to better adapt to the dynamic distribution characteristics of the inspection personnel in the distribution net-work,considering the hardware function of the positioning platform and the correlation between hardware and software algo-rithms,a dynamic and precise positioning platform is proposed for distribution station inspectors based on the tracking particle filter algorithm.Combined with the influence of positioning signal noise on positioning accuracy,the new platform is designed based on the tracking particle filter algorithm.The overall design can be divided into two parts:hardware and software.The hardware is completely designed for the overall structure,and the specific functional design and description of the receiving hardware is carried out;the software design is based on the auxiliary hardware,and optimizes the tracking particle filter algo-rithm.The expected effect is achieved through the initial particle filtering of the positioning signal of the inspection personmel,the iterative tracking optimization of the particle filtering,and the combined output of the particle tracking of the position data.The experimental results show that when six trackers are bownd,the maximum recognition value is 6,and the minimum value is 5;the positioning platform optimized by the tracking particle filter algorithm can achieve a dynamic positioning accuracy of more than 98％for inspection personmel.It can effectively solve the problems of large positioning deviation and low precision,it can adapt to a variety of condition variables and run stably,and has high promotion value.
