虚拟仪器与数据融合在瓦斯监测系统中的应用

井下瓦斯监测系统采用虚拟仪器及数据融合技术处理传感器检测的数据.数据采集卡采集并接收现场检测信息,经A/D转换送入计算机作分析与处理,提取特征.传感器检测的信息,通过自适应加权数据融合及多传感器数据融合,再采用D-S算法对融合后的信息二次融合,得出现场状态的估计并作出判断与决策.

Application of Virtual Instrument and Data Fusion in Gas Inspection System

Virtual instrument and data fusion technique are used to process the data inspected by sensors in gas inspection system. The information inspected in locale was collected and received by data acquisition card, and it was sent into computer. The information was analyzed and processed, and the character was extracted with computer after A/D conversion. The information inspected by sensors was fused with adaptive weighting and multi-sensor data fusion. Furthermore, the fused information was fused through D-S arithmetic again, and the estimation value of local estate is elicited and estimation and decision was made.
