摘　　要：为了快速准确地确定气体泄漏源的位置,提出基于加权质心算法的气体源定位法。采用气敏传感器对目标区域的气体浓度进行检测,并通过无线传感器网络把收集的数据反馈给协调器,协调器把打包好的数据传递给主处理器,处理器依靠测量的结果计算出气体源位置,并可视化显示。以乙醇蒸汽为实验目标气体,平均定位相对误差小于5.9%,验证了该方法的准确性。The gas source location method based on weighted centroid algorithm is proposed to determine the position of gas leakage source quickly and accurately. The gas sensor is used to detect the gas concentration of the target area. The wireless sensor network is used to feed the collected data back to the coordinator. The data after packaging is transmit to the main processor by means of the coordinator. The processor can calculate the gas source location for visual display according to the measured results. The experiment of taking the ethanol vapor as the target gas is performed,which can prove that the average relative error of location is less than 5.9%,and the gas source position algorithm is correct.
