Title:
無線通信異常検出方法、無線通信異常検出装置及び無線通信異常検出プログラム
Document Type and Number:
Japanese Patent JP6658357
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a processing load at radio fault analysis.SOLUTION: A gateway 10 includes: a valid parameter determination unit 40 which determines a valid parameter, on the basis of the values of a plurality of parameter types, indicative of radio quality with a sensor node, stored in a radio state DB 32; and an analysis unit 42 which classifies the parameter values collected in a predetermined period, among the parameter values determined to be a valid parameter, into a plurality of clusters, so as to analyze radio quality deterioration on the basis of the plurality of classified clusters. The valid parameter determination unit includes: a representative value calculation unit 14 which divides each predetermined period into a plurality of sections to calculate the representative value of each parameter in each of the plurality of sections; and a determination unit 20 which determines a parameter, having the standard deviation of the representative values in the predetermined period is larger than a threshold, to be a valid parameter.SELECTED DRAWING: Figure 3
