摘要
提出一种基于无源光网络的监测系统思路,利用现有通信传输网的光纤作为传感器,采用成熟的光时域反射仪(OTDR)模块和无源光网络(PON)相结合,可运用在高速公路的边坡断裂、垮塌监测中,并可以构成基于高速公路网的光传感监测网络。
The paper presents a passive optical network (PON) monitoring system, using the existing transmission network of optical fiber as a sensor, using sophisticated Optical Time Domain Reflectometer (OTDR) module and PON combination can be used in slope fracture highway, on the collapse of the monitoring, and the highway network can be constructed based on optical sensors monitoring network.
