基于WiFi和ZigBee的井下人员无线跟踪与定位系统的设计

Design of Wireless Tracking and Positioning System of Underground Personnel Based on WiFi and ZigBee

针对现有矿山人员定位系统成本高、安装复杂、只能区域定位等问题,提出了一种基于WiFi和ZigBee技术的井下人员无线跟踪与定位系统的设计方案和一种符合矿山实际要求的基于一维线性空间的实时定位方法,详细介绍了该系统的软硬件设计。该系统采用WiFi技术组建无线语音局域网络,采用ZigBee技术组建无线传感器监测网络,通过井下综合分站同时发射WiFi和ZigBee无线信号,实现了井下实时通信信号和定位信号的覆盖。该系统已实际应用,效果良好。

In order to solve problems of high cost,complex installation and limitation of zone location of current mine personnel positioning system,the paper put forward a design scheme of wireless tracking and positioning system of underground personnel based on WiFi and ZigBee and a real-time positioning method based on one-dimensional linear space which is perfectly fit for realistic requirement of mine underground,and introduced designs of hardware and software of the system in details.The system uses WiFi technology to construct wireless voice local network,uses ZigBee technology to construct wireless sensor monitoring network,and achieves coverage of real-time communication signals and positioning signals through integrated substations which can transmit WiFi and ZigBee signals simultaneously.The system has been applied with a good effect.
