摘要
无线通信技术在煤矿的管理运营中正发挥越来越重要的作用。文中通过对现有的无线通信技术进行分析研究,确定了无线射频技术在井下应用的优势;介绍了RFID射频终端(射频卡和读卡器)的硬件构造。由于RFID通信频段的选择对其运行效果影响显著,结合煤矿井下实际的通信环境选定了2.4 GHz的工作频段。现场测试显示系统运行达到预期效果。
The management of the wireless communication technology in underground coal mine operation is playing more and more important role.Through research and analyze the existing wireless communication technology,the advantages of radio frequency technology application in underground mine is confirmed in this article.And the hardware stuctureof RFID terminal(rf card and reader)is also introduced in this paper.Because the choice of RFID communication frequency band has a significant impact on its operation,this paper combines the actual communication environment of coal mine to select the working frequency band of 2.4 GHz.Field test shows that the system can achieve the desired effect.
