早期气体泄漏检测系统的开发对储罐场或化工厂的安全至关重要。接触式传统气体传感器不适用于大范围气体泄漏的远程监测。红外摄像机已被用于气体泄漏检测，但它仅限于检测特定气体。基于红外光谱成像系统，利用低成本、紧凑型微测热红外摄像机，研制了一套气体泄漏识别系统，实现了气体泄漏的检测、气体类型和气体密度的识别。通过对氢氟烃气体的识别实验，验证了该系统的可行性。
Development of an early gas leak detection system is essential for safety of energy storage tank fields or chemical plants. Contact-type conventional gas sensors are not suitable for remote surveillance of gas leakage in wide area. Infrared camera has been utilized for gas leak detection, however it is limited only for detecting particular gas. In this study a gas leak identification system, which enables us to detect gas leakage and to identify gas type and density, is developed based on infrared spectrum imaging system utilizing low cost and compact microbolometer infrared camera. Feasibility of the proposed system was demonstrated by experimental results on identification of hydrofluorocarbon gas.
