【摘要】：針對(duì)目前易燃易爆氣體泄漏監(jiān)測(cè)手段的不足,提出了一種使用光纖光柵傳感技術(shù)進(jìn)行實(shí)時(shí)監(jiān)測(cè)的方法。根據(jù)實(shí)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(duì)監(jiān)測(cè)點(diǎn)管道的振動(dòng)加速度進(jìn)行采集,利用降噪和傅里葉、變換的信號(hào)處理手段,對(duì)振動(dòng)波形進(jìn)行分析。結(jié)果表明:在管道發(fā)生泄漏時(shí),管道振動(dòng)的振動(dòng)加速度會(huì)發(fā)生一定程度的減小,振動(dòng)主頻會(huì)略微變大。通過光纖光柵傳感技術(shù),對(duì)振動(dòng)特征參數(shù)進(jìn)行分析和計(jì)算,可實(shí)現(xiàn)管道泄漏點(diǎn)準(zhǔn)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.
