虚拟仪器在矿井瓦斯监控系统中的应用研究

Application of Virtual Instrument and Data Fusion in Gas Inspection System

目前在井下瓦斯的检测系统采用的是数据融合技术和虚拟仪器来对传感器传送的数据进行处理。在数据融合时,主要是数据采集卡进行数据的采集和接收现场的监测信息,采集和接受的信息由计算机作进一步的分析和处理,最后做出判断。传感器监测的数据,通过自适应加权数据和多种传感器的数据融合,再采用先进的算法对融合的数据进行二次融合,得出更为准确的现场状态的估计,并作出相应的决策。

At present in the downhole gas detection system live to use is data fusion technology and virtual instrument to transmit sensor data processing. In data fusion, mainly is the data acquisition card for data collection and receive the monitoring information, collection and accept the information from the computer for further analysis and processing, finally make a judgment. Sensor monitoring data, through the adaptive weighted data and a variety of sensor data fusion, in the advanced algorithm fusion and data fusion secondary, it is concluded that the accurate state estimation, and make corresponding decision.
