AbstractAn intelligent robot watchdog for monitoring leakage of high-pressure gas in an oil refinery was presented. An automated abnormal-signal segregation and extraction technique based on inverse filtered acoustic/vibration signals proved effective for monitoring abnormal conditions in rotary machines, compressors, piping and high-pressure vessels. An intelligent sensor system detected leakage of high-pressure gases in oil refineries using pattern recognition techniques.
