AE technology,an advanced fault diagnosis technique,is impacted by environmental noise during\nmonitoring equipment. The occurrence of interfere noise,the fashion of interfere and the effect to the system in the AE\nautomatic online monitoring system is analyzed. At present, most of the acoustic emission signal transmission by\ncable, this way of transmission has a limited transmission distance, shortcomings and so on signal easily disturbed. Is\nproposed in this paper based on the optical fiber transmission technology, designed and developed a information\ncollection system based on optical fiber acoustic emission monitoring.This way has the advantages of long distance\ntransmission, strong anti-jamming capability.
