The invention provides a
metal carrying detection method based on a
wireless network. The
metal carrying detection method based on the
wireless network comprises the following steps that the step s1, a
wireless signal sending device and a
wireless signal receiving device are installed indoors; the step s2, the
wireless signal sending device continuously sends wireless electromagnetic wave signals; the step s3, the
wireless signal receiving device continuously receives the wireless electromagnetic wave signals; the step s4, abnormity analysis is continuously conducted on the received wireless electromagnetic wave signals through a
signal abnormity detection
system, and after analysis is conducted and abnormity is determined through judgment, the wireless electromagnetic wave signals in an abnormity
wave band are further analyzed in the step s5; the step s5, feature value extraction is conducted on the wireless electromagnetic wave signals in the abnormity
wave band through a data feature analysis
system, features of the wireless electromagnetic wave signals in the abnormity
wave band and features stored in an abnormity feature
library are compared and matched, and when the features of the wireless electromagnetic wave signals and the
metal features are successfully matched, an
alarm device is triggered. The metal carrying detection method based on the
wireless network has the advantages that installation and deployment are convenient, the cost is low, no damage to a
human body exists, the detection range is large, and the speed is high.
