Design on gas detection system based on porphyrin sensor

针对传统气体检测方法的不足,设计了一种基于卟啉传感器的快速气体检测系统。反应室的流体仿真表明该系统检测结果具有可比性。该系统采集存储卟啉传感器与气体反应前后的图像,通过图像处理技术获得传感器阵列的颜色变化信息,将其与数据库中的记录进行匹配,得到检测结果。实验表明:该系统响应快速,能准确检测识别多种有害气体。

A fast gas detecting system based on porphyrin sensor is designed to make up the deficiencies in traditional gas detecting methods. Fluid simulation in reaction room indicating that the detecting results are comparable. The principle of the system is to collect and store images of porphyrin sensor before and after the reaction with gas, and the changed color information can be obtained to match the records in database. The results prove the system can distinguish various harmful gasses accurately with a quick response.
