摘　　要：超高压直流阀厅套管具有设备长、重量大、安装难度高、各项安装工艺控制以及试验要求细等特点。使用了一种基于LED的可见光通信(Visible Light Communication,VLC)室内定位系统,并提出了一个基于逻辑斯蒂映射(Logistic Map)和类sigmoid函数(sigmoid-like function)改进的粒子群优化(Particle Swarm Optimization,PSO)的三维定位算法。该算法能极大地提高定位精度并减少计算时间,同时其更能反映实际情况,支持用户的移动性。仿真实验表明,该算法能以较高的精度和较快的收敛速度实现三维定位。The EHV DC valve hall bushing is characterized by long equipment length,high weight,difficult installation,various installation process controls,and fine testing requirements.An LED-based visible light communication(VLC) indoor positioning system is used and an improved particle swarm optimization(PSO) three-dimensional positioning algorithm based on logistic map and sigmoid-like function is proposed.The algorithm significantly improves positioning accuracy and reduces computation time,while it is more reflective of the actual situation and supports the user’s mobility.Simulation experiments show that the algorithm can achieve three-dimensional positioning with very high accuracy and fast convergence.
