基于三维可视化与Zigbee技术的真三维煤矿人员定位

针对现阶段煤矿人员定位系统定位不精确、成本高、不能实现真三维人员定位等问题,提出并实现了一种基于三维可视化与Zigbee无线传感器网络技术的真三维人员煤矿人员定位系统。从系统的设计与优化角度出发,较全面的分析了三维模型的创建与导出、真三维定位算法设计、微弱信号检测等关键性问题,构建了真三维人员煤矿人员定位系统,通过定位系统在安徽理工大学煤矿安全高效开采省部共建教育部重点实验室模拟巷道中的测试数据显示:在测试环境下,平均定位误差仅为0.76 m,较好的满足了煤矿工作环境下从业人员的定位需求。同时,较传统人员定位系统相比,真三维煤矿人员定位系统在定位性能、成本、操作性和视觉感官等方面具有较大的优势。

True three-dimensional coal mine personnel positioning system based on 3D visualization and Zigbee technology

Currently the underground positioning system is inaccuracy and costly.There is no true 3D personnel positioning system.This paper proposed and implemented a 3D visualization and personnel positioning system based on Zigbee wireless sensor network technology.From the perspective of design and optimization of the system，it made a comprehensive analysis of creation and export as 3D models，3D algorithm design as well as weak signal detection.Thus a true 3D personnel positioning system was constructed.From the test data of positioning system in simulative tunnel based on Provincial and MOE Joint Established Key Lab of Coal Mine Safety and High Efficient Mining of Anhui University of Science and Technology，the study finds that the average location error is only 0.76 m，which is better positioned to meet the needs of employees in a work environment under coal mine like the test environment.Meanwhile，the true 3D personnel positioning system has a greater advantage over the traditional personnel positioning in terms of positioning performance，cost，operability and visual senses.
