中文题目：井下人员定位系统设计外文题目：DESIGN OF UNDERGROUND PERSONNEL POSITIONING SYSTEM 摘要井下人员定位系统是为了提高煤矿人员管理效率和加强井下与地面信息沟通而设计的，该系统能够动态显示井下工作人员的实时位置，并能够对工人的工作时间和工作区域进行统计。本文首先分析了国内外井下人员定位技术的进展现状，并比较了其中的优缺点。分析了系统的工作原理，并进行了功能划分。系统在设计过程中采纳了模块化思想，从三个子系统分别对系统进行设计。文中重点讨论了井下的无线通信问题，并选择了 RFID（射频识别）为井下无线通信方案；在井下与地面的通信方式中选择了技术先进、性能可靠的 CAN 总线技术；在地面监控端结合当前的新技术采纳了 GIS（地理信息系统）进行井下监控情况的实时显示。关键字：井下人员定位；RFID；CAN；GISAbstractUnderground personnel positioning system is designed to improve the management efficiency of coal miners and strengthen the communication between the ground and underground .The system can dynamically display the real-time location of underground staff and record the working hours and regions of workers.In this paper, we first dicussed the development of mine personnel positioning technology at home and abroad , and compared the advantages and disadvantages of them. Then we put forward the idea of the design of positioning system, and analysised its working principle and. During the process of design we submit the system into some models and design the system form three sub-systems.In the process we focused on the issue of underground wireless communication, and select the RFID (radio frequency identification) for underground wireless communications program. To solve the problem of communication with the ground we select the CAN bus technology,which was technologically advanced and has reliable performance. In designsing of the monitoring on the ground side, we use the GIS(Geographic Information System) ...
