| 摘 要： | 通过分析管道燃气泄漏所产生的超声波信号的声压、泄漏流速与雷诺数之间的关系,利用嵌入式DSP技术和降频原理,可以及时、准确地判断管道燃气有无泄漏、泄漏点的具体位置以及泄漏量的大小,从而实现了对燃气管道的实时监控,对于节约能源、人力资源和减少环境污染具有重要的意义。

| Abstract: | By analyzing the relations between the sonic pressure of ultrasonic signal produced by ducted-gas leaking,the leakage flow and the Re,utilized the embed type DSP technology and frequency-lowing theory to accurately and timely locate if any,the leakage point,and measures the amount of leakage.Consequently,real-time monitoring of the ducted-gas was realized.It is of great significance to economization of energy human resources and less environmental pollution. |
