【摘要】：針對目前易燃易爆氣體泄漏監(jiān)測手段的不足,提出了一種使用光纖光柵傳感技術(shù)進行實時監(jiān)測的方法。根據(jù)實際工況搭建了管道輸氣系統(tǒng),使用空氣作為傳輸介質(zhì)模擬了易燃易爆氣體發(fā)生泄漏的過程。通過對監(jiān)測點管道的振動加速度進行采集,利用降噪和傅里葉、變換的信號處理手段,對振動波形進行分析。結(jié)果表明:在管道發(fā)生泄漏時,管道振動的振動加速度會發(fā)生一定程度的減小,振動主頻會略微變大。通過光纖光柵傳感技術(shù),對振動特征參數(shù)進行分析和計算,可實現(xiàn)管道泄漏點準確定位。
[Abstract]:In view of the shortage of current flammable and explosive gas leakage monitoring means, a method of real-time monitoring using fiber Bragg grating sensing technology is proposed. A pipeline gas transmission system is built according to the actual working conditions. Air is used as a transmission medium to simulate the process of leakage of flammable and explosive gas. The vibration acceleration of the monitoring point pipe is achieved. The vibration wave is analyzed by means of noise reduction and signal processing by Fu Liye and transformation. The results show that the vibration acceleration of the pipe will decrease to a certain extent and the main frequency of the vibration will be slightly larger when the pipeline leaks. The vibration characteristic parameters are analyzed and calculated by the fiber grating transmission technology. The accurate location of the leakage point of the pipeline is realized.
