Abstract

A personnel presence detection device, a personnel presence detection system, and a personnel presence detection method are disclosed. The personnel presence detection device includes a signal transmitting module for transmitting Wi-Fi signals, a signal receiving module for receiving Wi-Fi reflected signals, a processor for obtaining channel state information (CSI) data based on the Wi-Fi reflected signals, and a computing module for identifying a main radio-frequency path from CSI data set. The computing module processes the CSI data set to determine whether the highest frequency value falls within the respiratory frequency range and generate a first detection result; determine whether the signal variance is greater than a preset value and generate a second detection result; determine whether the number of packets is less than a preset value and generate a third detection result. If any of the three detection results is true, it determines that a person is present.
