基于光缆振动的井下无源定位系统的研究
Study of mine passive location system based on fiber cable vibration
摘要
Abstract
When mine disaster happens, aiming at the problem that the trapped miners are difficult to be posi-tioned, according to the interference principle and the φ-OTDR technology, a method of underground passive location based on optical cable vibration is put forward in this paper, and a passive location system which based on this method is designed. The vibration caused by the trapped miners hitting the optical cable includes sound information and location information. By analyzing the audio data, it can distinguish accidental vibra-tion and regular knocking vibration. By computing OTDR data, it can get the location of vibration. The test re-sults show that the system can reduce the vibration sound and determine the knocking position, and the stan-dard deviation of the positioning distance is within 11m.关键词
