RFID技术在井下救援定位中的应用研究

Research on Application of RFID Technology in Underground Rescue Location

煤矿井下安全救援由于井下环境复杂,且红外探测和生命探测仪器的应用受到诸多限制,开发一种用于煤矿救援的井下人员定位装置具有非常重要的作用。提出了一种基于RFID技术的井下定位装置,在分析煤矿井下定位系统的需求基础上,对系统的发送模块和接收模块进行了设计,提出了系统低功耗的设计方法,阐述了RFID人员定位技术中RSSI定位算法和KWWN算法,提出使用混合算法进行井下人员的定位方法。构建仿真环境并进行了仿真,改变K值,当K=4时对人员定位的误差值最小,系统能够满足煤矿井下救援定位的需求。

Due to the complex underground environment of coal mine safety rescue,and the application of infrared detection and life detection instruments is limited,it is very important to develop a kind of underground personnel positioning device for coal well rescue.A kind of underground positioning device based on RFID technology was proposed.Based on the analysis of the demand of underground positioning system in coal well,it designs the sending module and receiving module of the system,puts forward the design method of low power consumption,and expounds the RSSI positioning algorithm and KWWN algorithm in RFID personnel positioning technology.A hybrid algorithm is proposed to locate underground personnel.The simulation environment is constructed and the simulation is carried out.Changing the value of K,it is found that when K=4,the error value of personnel positioning is the smallest,and the system can meet the needs of underground coal well rescue positioning.
