摘要
为实现一种针对隧道等特殊环境的监测方案,设计了一种光纤传输方式,主要包括常温光收发模块、高温光收发模块及多模光纤链路三部分。在分析案例应用场景及高温光收发模块耐温状况、传输距离、带宽等条件下,研究了微弱光电信号的抗噪放大电路,并设计了在高温中快速实时传输语音、视图等信息的方案。该方案证实了能够提供宽带、远程、紧凑、强抗电磁干扰的全双工传输,对于极端环境(比如隧道监测、油田测井等)施工、运营现场的实时监控、方案的调整或优化、生产效率的提高具有重要的经济价值和社会效益。
In order to realize a monitoring scheme suitable for tunnels and other special environments, an optical fiber transmission mode was designed in this paper, which includes three parts of normal-temperature transceiver module, high-temperature transceiver module and multimode optical fiber link. Based on analyses on case application scenarios, heat-resistant status of high-temperature optical transceiver module, transmission distance and bandwidth, the anti-noise amplifier circuit of weak electro-optical signal was investigated. A scheme on fast real-time transmission of voice and video in high temperature was designed, which can provide the full-duplex transmission with broadband, remote, compact and strong anti-electromagnetic interference. It has the important economic value and social benefit for the real-time monitoring, scheme adjustment and optimization of the spots of construction and operation in the extreme environments such as tunnel monitoring and oil field logging.
