基于传感器阵列的恶臭气体检测

摘要

In order to monitor odorous gases in the air,a composite stench gas monitoring system was designed.The system was based on the sensor array,used multi-sensor information fusion technology,identified composite stench gas composition and calculated the stench.Using pig farms stink gases as the sample gas to conduct experiments and their response curve was analyzed.The relationship between characteristic value of gases and the stench was gotten,thus providing basis for the detection of odorous gases.Experiments show that the stench gas detection technology based on sensor array has good application prospect.%为了监测空气中的恶臭气体,设计一种复合恶臭气体监测系统.该系统以传感器阵列为基础,采用多传感器信息融合技术,识别复合恶臭气体成分并计算出恶臭值.以养猪场恶臭气体为样气进行实验并分析其反应曲线,得出气体特征值与恶臭值之间的关系,为检测恶臭气体提供依据.实验证明,基于传感器阵列的恶臭气体检测技术具有良好的应用前景.
