井下人员定位系统毕业设计.doc

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发展现状，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用了模块化思想，从三个子系统分别对系统进行设计。文中重点研究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用了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；GIS Abstract Underground 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) combined with the currentthe new technology to monitor the situation of underground and pit the real-time display. Key words: positioning of underground personnel; RFID; CAN; GIS 目录 1 绪论 1 1.1 煤矿生产管理中的问题 1 1.2 选题意义 2 1.3 井下人员定位系统的发展现状 3 1.3.1 国外研究状况 3 1.3.2 国内发展现状 3 1.4 井下人员定位系统设计的难点问题 4 1.5 本设计所做的工作 5 2 井下人员定位系统的基本原理 6 2.1 定位系统概述 6 2.2 井下人员定位系统的基本原理 6 3 系统的功能划分 9 3.1 井下无线监测子系统 9 3.2 地面数据处理子系统 9 3.3 井下与地面通信子系统 10 4 井下无线通信子系统设计 12 4.1 通信的基本知识 12 4.1.1 信号的转换与编码 12 4.1.2 差错控制
