摘要
针对现有井下人员定位系统亟待解决的功耗、漏检率和定位精度等技术问题,从探讨基于ZigBee通信技术的无线传感器网络体系架构出发,对人员无线定位系统中的传感器终端设计、定位机制及无线网拓扑等关键技术进行了较为深入的研究,给出了传感器节点设计、定位算法以及无线组网等工程实现过程,及各单元模块所采用的技术优化或改进策略,改善了现有系统的综合性能.
In view of the technical problems about power dissipation,miss rate and localization accuracy of existing mine personnel localization system,starting from the system architecture of wireless sensor network based on ZigBee communication technology,the key techniques of sensor terminal design,localization mechanism and wireless network topology were in-depth researched.In this paper,engineering realization of the sensor node design,localization algorithm and wireless networking technology were given,optimization of technology or improvement of strategies was proposed in each unit module.They can improve the comprehensive performance of the existing wireless sensor localization system.
