摘要
利用超声换能器阵列采集泄漏超声信号,采用TMS320f2812芯片作为仪器的信号处理芯片和LabVIEW图形化开发语言,研制了手持式检测仪和泄漏分析软件结合的气体泄漏检测系统。该检测系统检测精度较高,对气体泄漏可以实现实时检测与趋势预测,将该系统在某型军用飞机上进行实验验证,验证该仪器的检测精度。
Ultrasonic transducer array collected leak ultrasonic signals were used,chip TMS320f2812 was adopted as the instrument signal processing chip and LabVIEW programming analysis software.This paper developed a hand-held aircraft gas system leak detector and leak analysis software,which constitute detection system.The system has real-time detection and post analysis function,real-time detection and forecast of gas leakage trend can be achieved,simultaneously achieve air tightness testing of intelligent demand.
