Problems solved by technology

[0004] The applicant found that the technical solution of patent application document 1 needs to add an antenna array at the transmitting end and the receiving end at the same time, which cannot work for a Wi-Fi terminal device with a single antenna or only a small number of antennas, and most wireless Wi-Fi terminals on the market Devices have only a single or a small number of antennas, making the technology not widely available
In addition, the technical solution of patent application document 1 adopts technologies such as AoA and MIMO to establish a channel model, and the cost of the required hardware equipment and the computational workload of the software are huge
The Wi-Fi detector in Patent Application Document 2 has a single working mode and can detect information such as the data speed of the Wi-Fi signal, but cannot determine the direction of the Wi-Fi signal source

Abstract

The invention relates to a Wi-Fi signal detection device and a Wi-Fi signal detection method. The Wi-Fi signal detection device comprises: a spherical directional antenna array comprising a plurality of antenna units configured to respectively detect Wi-Fi signals of electronic devices in different directions; a probe array including a plurality of probe units corresponding to the plurality of antenna units, each probe unit being connected to one antenna unit and configured to switch among a plurality of channels of the Wi-Fi signal at a predetermined period to obtain probe data of the plurality of channels; and the controller is configured to establish a data set taking the MAC address of the electronic equipment as an index according to the detection data, and obtain directivity information of each piece of electronic equipment according to statistical distribution characteristics of the data set. According to the method, the specific direction of the electronic equipment can be obtained with relatively small calculation amount and calculation time.

Description

technical field [0001] The present disclosure relates to the technical field of signal detection, and in particular, to a Wi-Fi signal detection device and a Wi-Fi signal detection method. Background technique [0002] Chinese Patent Application Publication No. CN110049551A (hereinafter referred to as Patent Application Document 1) discloses a signal tracking method based on commercial wireless Wi-Fi equipment. A commercial wireless Wi-Fi device is used to obtain the channel state parameters in the process of Wi-Fi signal propagation. According to the relationship between the antenna array structure and the direction of Wi-Fi signal propagation, a mathematical model of Wi-Fi array signal transmission based on channel state parameters is established. ; Decompose the eigenvalues ​​of the transmission mathematical model, and use the minimum description length criterion and the relationship between the eigenvalues ​​to analyze the number of Wi-Fi signal multipath propagation; ac...
