煤矿井下人员定位系统的研究和实现

Research and Implementation of Person Positioning System in Coal Mine

针对我国煤矿安全现状,研究确定了一种基于RFID和嵌入式技术的煤矿井下人员定位系统.详细介绍基于RFID技术的煤矿井下人员定位系统的主要结构和工作原理.整个系统采用无线数据采集,有线传输的方式;每名井下人员配有一身份码发送器,通过发送无线信号把自身的人员编号发送出去,井下沿巷道设置身份码监测站通过接收无线信号来收集人员信息数据;井下各个监测站收集到的数据通过电缆传至地面主机;由基于嵌入式技术的主机完成对数据的分析、处理和存储;地面主机和井下各监测站采用CAN现场总线协议连接构成一个完整的系统.最后,给出了系统的软件框图.

Aiming at the safety status of domestic coal mine, a person position system in coal mine based on RFID and the embedded technology was researched and established.Main system structure and working principle of underground mine personnel positioning were detailed.The system used wireless data collection,and data transmission went through the cable.Each officer in the mine was equipped with a transmitter that could send their identity personnel numbers using radio signals out.Along the roadway,the status code station set underground by receiving radio signals could gather information and data staff.The data of mine were collected in all stations and were transmitted to the ground host through the cable.The data analysis,processing and storage were processed by the host based on embedded technology.Ground host and underground monitoring stations used CAN field bus to form a perfectly connected system.At the end of the paper,the software’s block diagram was offered
