| 摘 要： | 为了提高井下广域范围的通信质量,降低系统的复杂性,采用有线直接耦合的方式采集信号源数据,利用多链路光纤直放系统将全球移动通信系统（GSM）900 MHz信号延伸到井下。系统的近端机和各远端机采用双纤单向传输,其地面基站（BTS）到井下远端机的最远距离应不大于20km。应用表明,该系统能够适应井下的动态生产环境,是实现井下广域范围移动通信的较佳方式。 |

| Abstract: | This paper is an endeavour to improve the communication quality and reduce system complexity in mines by using a mobile communication,which consists of use of the direct cable coupling for collecting signal source data and use of the multi-link fiber repeater system for extending GSM(Global System for Mobile Communications) 900 MHz signal to mines.The proximal modulation apparatus and the remote apparatuses use dual-fiber transmission and the most distance from the ground BTS(base station) to the remote app... |
