【摘要】：随着我国对矿产资源需求的日益增长,井下开采作业也随之增多,我国政府对井下安全作业也给予了高度的重视。而要确保井下作业的安全,开发和应用井下人员定位系统是有效的可行途径之一。井下人员定位系统是综合性安全防护与人员管理的应用系统,具有强大的作业人员信息管理、实时位置跟踪、险情预警及灾后辅助救援等功能。因此对该系统的应用研究对于加强我国井下产业的安全生产有着十分重要的意义。本课题在对国内外现有的井下人员定位系统的深入了解与分析的基础上,对一种基于单片机网络及无线技术的井下人员定位系统进行了应用研究。无线传输技术使系统具有对移动设备检测的灵活性,同时解决了井下器件维护困难等问题。利用基于开放的、标准的、独立于系统平台的小型嵌入式uIP0.9协议栈的单片机网络技术,可将数据更加可靠、方便且低廉地通过网络传输到远程终端。本应用研究主要是利用设置在井下监测区域内大量的低功耗微型单片机网络服务器,各服务器与移动通信终端间以无线通信方式形成一个无线网络系统,在此无线网络覆盖区域内单片机网络服务器自动地识别、采集和处理被监测的移动通信终端的信息。其中主要应用2.4GHz射频无线传输技术进行无线数据传输,并通过对移动通信终端ID号的查询来确认移动人员,再以单片机网络技术为核心实现数据的网络传输。其特点是结构简单、实时性强、可远程操作且容易实现,能够长期工作于无人值守的区域,实时地向地面控制中心报告监测情况。本应用研究主要分为3个部分：第一部分为井下人员定位系统的硬件电路设计。主要是移动通信终端及具有无线通信功能的单片机网络服务器的主要芯片选型、各器件工作原理分析及各功能模块的电路设计。主控芯片选用STC12LE5A60S2低功耗单机器周期单片机,无线通信模块选用以nRF24L01无线射频收发芯片为核心的2.4GHz通信模块,两者之间以SPI总线接口方式通信。数据的网络传输主要由RTL8019AS以太网控制器辅以锁存器74VHC573、存储器62256及滤波变压器FB2022完成,最后通过RJ45接口实现与网络的连接。第二部分为井下人员定位系统下位机软件程序设计。可分为两部分：利用nRF24L01无线收发芯片的点对多点通信及自动重发与自动应答功能,实现单片机网络服务器与移动通信终端之间的无线数据通信及对移动通信终端ID号的查询功能；利用uIP0.9协议栈与以太网驱动程序相配合实现数据在网络上的发送与接收功能。第三部分为上位机管理软件的开发。利用Delphi7可视化程序开发工具及其自有的Padadox7数据库开发人员定位系统的管理软件；在管理软件后台利用强度检测的M值对人员进行区域定位,并在理论上研究了一种改进的RSSI定位算法,同时利用Socket套接字的C/S模型实现单片机网络服务器与上位机的通信；
[Abstract]:With the increasing demand for mineral resources in our country, the underground mining operation is also increasing, and our government has also attached great importance to the underground safe operation. To ensure the safety of underground operation, the development and application of downhole personnel positioning system is one of the effective and feasible ways. The downhole personnel positioning system is an application system of comprehensive safety protection and personnel management. It has powerful functions of information management, real-time location tracking, danger warning and auxiliary rescue after disaster and so on. Therefore, the research on the application of this system is of great significance to strengthen the safety production of underground industry in our country. Based on the deep understanding and analysis of the existing downhole personnel positioning system at home and abroad, this paper studies the application of a downhole personnel positioning system based on single-chip computer network and wireless technology. Wireless transmission technology makes the system flexible to detect mobile devices and solves the difficulties of downhole device maintenance. Based on the open, standard and independent embedded uIP0.9 protocol stack, the data can be transferred to the remote terminal more reliably, conveniently and cheaply. This application research is mainly based on a large number of low-power microcontroller network servers set in the underground monitoring area, and a wireless network system is formed between each server and the mobile communication terminal in the form of wireless communication. In the wireless network coverage area, the MCU network server automatically identifies, collects and processes the information of the monitored mobile communication terminal. The 2.4GHz radio frequency wireless transmission technology is mainly used for wireless data transmission, and the mobile communication terminal ID number is queried to confirm the mobile personnel, and then the MCU network technology is the core to realize the network data transmission. It is characterized by simple structure, strong real-time, remote operation and easy implementation. It can work in unattended areas for a long time and report the monitoring situation to ground control center in real time. The application research is mainly divided into three parts: the first part is the hardware circuit design of downhole personnel positioning system. It is mainly about the selection of the main chips of the mobile communication terminal and the MCU network server with wireless communication function, the analysis of the working principle of each device and the circuit design of each function module. The main control chip is STC12LE5A60S2 low power single machine cycle MCU, and the wireless communication module is 2.4GHz communication module with nRF24L01 radio frequency transceiver chip as the core. The communication between them is based on SPI bus interface. The network transmission of data is mainly accomplished by RTL8019AS Ethernet controller supplemented by latch 74VHC573, memory 62256 and filter transformer FB2022. Finally, the connection to the network is realized through RJ45 interface. The second part is the software design of downhole personnel positioning system. It can be divided into two parts: point to multipoint communication, automatic retransmission and automatic reply function of nRF24L01 wireless transceiver chip. Realize the wireless data communication between the network server and the mobile communication terminal and inquire the ID number of the mobile communication terminal; The uIP0.9 protocol stack and Ethernet driver are used to realize the function of sending and receiving data on the network. The third part is the development of upper computer management software. Using Delphi7 visual program development tools and its own Padadox7 database developer positioning system management software; In the background of the management software, the M value of intensity detection is used to locate the area of the personnel, and an improved RSSI location algorithm is studied theoretically. At the same time, the communication between the MCU network server and the host computer is realized by using the C / S model of the Socket socket.
