Design of a Photoacoustic Gas Detection System for Fire Warning

Chen Tao,Su Guofeng,Shu Xueming,Yuan Hongyong,Fan Weicheng

Strategic Study of CAE 2004, Volume 6, Issue 7,   Pages 60-64

Abstract:

The requirements and principles of using photoacoustic gas detection technique in fire detection areaare discussed and an unusual photoacoustic gas detection system is presented.Common photoacoustic gas detection systems in laboratories are not suitable for fire warning becauseAt first when there is no combustion gas in the absorption path, the CO cell absorbs the light radiation

The Fire Detection Technology of Multiple Gases Based on Photoacoustic Principle

Jiang Yalong,Yuan Hongyong,Zhang Yongming,Liu Yong,Zhu Yuquan,Wang Jinjun

Strategic Study of CAE 2006, Volume 8, Issue 8,   Pages 69-72

Abstract: But the measurement of physical parameters is not enough for an early fire detection.A majority of existing gas sensors are not good for a early fire detection because of their low sensitivityA detection method for measuring the gas concentration based on photoacoustic principle is reported inThe rate of false alarm is decreased greatly also by combining carbon monoxide detection with carbondioxide detection.
