Research on Technology of Gas Pipeline Leakage Detection Based on Infrasonic Wave

Abstract:

In the field of natural gas pipeline leak detection, based on infrasonic wave method of gas pipeline leak detection technology gradually be taken seriously. This paper introduces the basic features of pipeline leak signals and basic principles of infrasonic wave leak detection technology. It analyzes the key factors, which affect accurate positioning. According to the characteristics of leak signal and performance requirements of leakage monitoring system, the infrasonic wave speed algorithm in gas pipeline is modified. Using correlation analysis and wavelet transform method on the leakage signals, the dynamic response time diversity between sensors installed in first and last stop will be more precise. As a result, it improves the positioning precision of leak detection effectively.
