一种探测光缆衰减参数的自动校准方法及装置
摘要：
本发明公开了一种探测光缆衰减参数的自动校准装置，探测光缆尾端的光通过自动校准装置反射进入探测光缆，反射进入探测光缆中的光产生的后向散射光再次通过自动校准装置由探测光缆进入分布式光纤温度传感系统进行数据处理，最终得到探测光缆的两次数据信息，用以校准探测光缆的衰减参数。本发明还公开了一种探测光缆衰减参数的自动校准方法。实施本发明的探测光缆衰减参数的自动校准方法及装置，能够准确获得探测光缆的衰减参数，实现在现场对探测光缆进行校准、补偿；增加了分布式光纤温度传感系统的有效使用程度，提高了分布式光纤温度传感系统的性能。
摘要（英）：

The invention discloses a device for automatically calibrating an attenuation parameter of a detection optical cable. Light at the tail end of the detection optical cable is reflected by the automatic calibrating device to enter the detection optical cable; rearward scattered light generated by the light entering the detection optical cable after being reflected enters a distributed optical fiber temperature sensing system again from the detection optical cable by the automatic calibrating device to carry out data processing; and finally, twice data information of the detection optical cable is obtained for calibrating the attenuation parameter of the detection optical cable. The invention also discloses a method for automatically calibrating the attenuation parameter of the detection optical cable. After the method and the device for automatically calibrating the attenuation parameter of the detection optical cable, which are disclosed by the invention, are implemented, the attenuation parameter of the detection optical cable can be accurately obtained and calibration and compensation on the detection optical cable in the field are implemented; and the effective use degree of the distributed optical fiber temperature sensing system is improved and the performance of the distributed optical fiber temperature sensing system is improved.
