摘要
针对传统电缆在煤矿井下监控系统的数据传输中存在距离短、速度慢、损耗大、抗电磁干扰能力弱等问题,对光纤传输技术、光收发模块原理进行了研究,在井下传感器等监测设备终端与监控分站之间,提出一种单模单纤的光纤模组传输方案。详细介绍了光纤传输模组总体结构、光模块的发送和接收原理、以及光模块在传感器中的应用,并结合实际应用,测试了光纤传输在传感器与监控分站之间的信号传输性能,符合实际应用需求。
Aiming at the problems of short distance, slow speed, large loss and weak anti-electromagnetic interference ability of traditional cable in data transmission of coal mine monitoring system, this paper studies the optical fiber transmission technology and the principle of optical transceiver module, and puts forward a single-mode single fiber optical fiber module transmission scheme between the monitoring equipment terminal such as underground sensors and the monitoring substation. The paper introduces the overall structure of the optical fiber transmission module, the sending and receiving principle of the optical module,and the application of the optical module in the sensor. Combined with the practical application, the signal transmission performance of the optical fiber transmission between the sensor and the monitoring substation is tested, which meets the actual application requirements.
