基于加权质心算法的气体源定位系统
Gas source location system based on weighted centroid algorithm
摘要
Abstract
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.关键词
