新型光纤传感高速公路智能电缆的设计与应用

Design of a Novel Optical Fiber Sensing Intelligent Cablefor Highway

文中介绍了一种适用于高速公路上的智能电缆,该新型电缆结构中包含有光纤光栅阵列光纤作为温度及振动传感器,可对高速公路沿线设备用电缆、隧道中的风机电缆等在运行中进行温度监测和防盗监测,可有效地对温度和振动变化时的电缆进行快速预警,精确定位。

A intelligent cable for highway is introduced. The new cable structure includes fiber bragg grating arrays as temperature and vibration sensor, which can carry out temperature monitoring and anti-theft monitoring on the cable for equipment along the highway, the fan cable in the tunnel, etc., and it can effectively warn and accurately locate the cable when the temperature or vibration change.
