Description

technical field

[0001] The invention relates to a monitoring method for a distributed optical fiber sensing system, in particular to a method for laying optical fibers used in a distributed optical fiber sensing system, and belongs to the field of optical fiber technology. Background technique

[0002] The monitoring principle of the distributed optical fiber sensing system is: at the same time, the optical fiber is used as the sensing sensitive element and the transmission signal medium, and the advanced OTDR technology is used to detect the temperature and strain changes at different positions along the optical fiber, so as to realize the truly distributed Measurement. The distributed optical fiber sensing system is a new type of detection system for real-time measurement of temperature or stress distribution. It has the advantages of long measurement distance, high measurement accuracy, accurate positioning, fast response speed, and flexible alarm methods. In recent year...
