摘 要:针对目前煤矿井下人员跟踪定位系统存在信息无法实时沟通和对人员不能进行全程连续跟踪定位的问题,设计出一种基于射频(RF)电磁波且采用TOA定位方法的井下人员呼救报警系统,详细介绍了井下人员定位、跟踪、遇险时主动呼救报警和实时通话功能的具体实现过程及其工作原理。介绍了系统中关键设备基站与人载报警仪结构原理,系统经初步测试,结果表明,在井下视距(LOS)环境,定位误差小于0.5 m,非视距(NLOS)环境,定位误差为5-8 m,并且通信的可辨度和报警信号的灵敏度能适应井下环境要求。According to the existing problems existed in the present mine underground personnel tracing system that the information could not real timely communicate and the underground personnel could not be wholly and continuously traced and positioned,a mine underground personnel paging alarm system was designed based on the radio-frequency electromagnetic wave and with TOA positioning method.The paper in detail introduced the certain implementation processes and working principles of the mine underground personnel positioning,tracing,emergency active paging alarm and real time communication functions.The paper provided the structural principle of the key equipment based station and personal carried alarm device in the system.The system had passed the preliminary test and the test results showed that in the line of sight environment,the positioning error would be less than 0.5 m and the no line of sight environment,the positioning error would be within 5~8 m.The communication distinguishable degree and the alarm signal sensitivity of the system could be suitable to meet the requirements of the mine underground environment.
