加强煤矿井下工作人员的定位管理对于安全生产、提高工作效率至关重要。为此,运用ZigBee技术,提出了一种基于CC2431的井下人员定位系统,通过井下传感器节点实时接收到移动节点的信号,借助上位机软件,实现地面控制中心对下井人员实时定位、信息采集及身份识别。测试实验表明系统能准确地获取井下人员实时位置,可对下井人员进行实时考勤,能给煤矿事故发生后的应急救援提供科学决策参考。
Strengthening coal mine underground staff’s position management is very important to work safety and improve work efficiency. Therefore, using ZigBee technology, this paper presents a downhole personnel positioning system based on CC2431, which receives signals from mobile nodes in real time through downhole sensor nodes and realizes the real-time location, information collection and identity of downhole personnel with ground computer software Recognize. Tests and experiments show that the system can accurately obtain the real-time location of downhole personnel, and can perform real-time attendance for downhole personnel and provide scientific decision-making reference for emergency rescue after coal mine accident.
