摘　　要：目的建立一种漏气监测系统,监控医院"三气"管道和气瓶的气体泄漏情况。方法利用数字信号处理技术对泄漏所产生的超声波信号进行分析处理和声压级计算,从而实现对泄漏的检测及泄漏量的估算。结果医院能有效地实时监控气体泄漏情况,杜绝医疗隐患。结论该系统性能可靠,可移植性强,市场前景广阔。Objective To monitor gas leakage of gas pipeline or gas cylinder in hospital, this study developed a gas leakage monitoring system. Methods The digital signal processing technology was adopted to analyze and process the ultrasonic signal produced by leakage and the acoustic pressure level calculation, thus the leakage detection and leakage amount estimation were realized. Results The gas leakage was realtimemonitored effectively and the medical risk was prevented. Conclusion This system has stable performance, strong portability and wide market prospects.
