Abstract:: Ultra-wideband positioning has been widely used as a high-precision indoor moving object positioning tracking or navigation technology. The traditional UWB positioning model usually uses the Taylor series iterative algorithm to achieve positional solution. However, the Taylor series positioning solution has strongly dependence on the initial value. To improve the robustness and positioning accuracy of the positioning solution method, a novel ultra-wideband localization solution based on differential evolution algorithm and Taylor series iteration is proposed. Calculation method. Taking the positioning error as the optimization target, the differential evolution algorithm is used to achieve the global position of the target point. Furthermore, the optimal positioning point obtained by the differential evolution algorithm is used as the initial value, and the Taylor series iterative algorithm is used to locally optimize the positioning point to obtain more precise target positioning. Aiming at the complex indoor scene of coal mine roadway, the proposed method is used to realize the UWB positioning calculation of the excavation support mobile bracket. The experimental results show that the proposed method has higher positioning resolution accuracy than the existing positioning solution method.
