提出并实现了一种新型带盲区的煤矿巷道人员全局定位系统,介绍了国内外煤矿人员定位系统的研究现状,分析了发展带盲区巷道网络全局定位系统的必要性.从系统应完成的目标角度考虑,较全面地分析了全局定位系统中的基本问题、数据模型、拓扑优化及全局定位等关键问题;构建了全局定位原型系统,并对定位系统在地下巷道环境进行了较全面的实验测试.将全局定位系统和现有的煤矿人员定位系统进行了对比分析,结果表明:全局定位系统在功能、定位性能、成本、可靠性和可维护性等方面具有较大优势.%Proposed a novel personnel positioning scheme in tunnel network with blind areas. Investigated current research of the mine personnel positioning system, and analyzed the necessity of developing a global positioning system with blind areas. Developed a more comprehensive analysis of the basic issues, data model, topology optimization, and global positioning issues of MPGPS. Constructed prototype system and made a comprehensive test in the underground tunnel environment. Compared MPGPS with the existing RFID positioning system and the Zigbee positioning system,MPGPS has some advantages in the function, the positioning precision, the cost, the reliability and maintainability.
