Problems solved by technology

[0004] Among the above-mentioned technical solutions based on wireless signal positioning, some solutions need to rely on additional sensors or other signal sources for positioning prediction, and the other part needs to bind wireless devices to the detected objects or human bodies, and use the portable devices to receive each AP. There are technical problems such as complicated wiring and high application cost, which are not conducive to popularization.

Embodiment 1

[0042] like figure 1 As shown, the wireless signal positioning method includes the following steps:

[0043] 1) Area division: Divide the effective area into multiple sub-areas as data sampling points; specifically, divide the effective area into multiple squares, rectangles or hexagons, for example: divide the rectangular room into multiple 30cm* of equal area For a square of 30cm, in general, the outline of the divided sub-regions ranges from 10cm to 50cm.

[0044] 2) Wireless signal collection: Move objects or human bodies to different data sampling points in turn, and record the impact data corresponding to multiple wireless devices in the wireless network in sequence; specifically, human bodies or objects in different positions will absorb and reflect signals , to generate different impact signals, therefore, let the user enter different sampling points in turn to record the corresponding impact data.

[0045] It should be noted that wireless signals include but are not...

Embodiment 2

[0053] In this embodiment, the data record format in the wireless signal collection process is:

[0054] f i =(L i , H i , CN i , N i , C i , W i , D i , T i ,MAC i1 , RSSI i1 ,CSI i1 ,LQI i1 ...,MAC in , RSSI in ,CSI in , LQI in ), where: L i Indicates that the object or human body is at the i-th sampling point; H i Indicates the state of the object or human body in the i-th sampling point; CN i Indicates the network communication situation in the current collection area; N i Indicates the network communication situation of the non-current collection area; C i Indicates the state of the curtains in the effective area when recording the i-th sampling point data; W i Indicates the state of windows in the effective area when recording the i-th sampling point data; D i Indicates the state of the door in the effective area when recording the i-th sampling point data; T i Indicates the recording time for recording the i-th sampling point data; MAC in Indicat...

Embodiment 3

[0057] The fingerprint data model included in the original data is as follows:

[0058]

[0059] Among them, the fingerprint data model includes the recorded data of all sampling points, where: L m Indicates that the object or human body is at the mth sampling point; H m Indicates the state of the object or human body in the mth sampling point, for example: use different parameters to represent the state of no one, one person, many people, people sitting, standing, etc.; CN m Indicates the network communication status of the current collection area, and judges whether there are activities such as watching videos, playing games, and transferring files in the current collection area; N m Indicates the network communication situation in the non-current collection area, and judges whether there are activities such as watching videos, playing games, and file transfers in the non-current collection area; C m Indicates the state of curtains in the effective area when recording t...

Abstract

The invention provides a wireless signal positioning method and a wireless signal positioning device, and belongs to the cross technical field of wireless network and deep learning, the method utilizes the deep learning technology to explore the regular influence of a moving object or a human body on a wireless signal, and constructs a weight model between the object position and wireless signal influence data; the position of the current object is predicted by monitoring and analyzing wireless signal influence data in real time, compared with the prior art, the position of the moving object or the human body in an effective area can be stably, rapidly and accurately predicted without binding wireless equipment, the method can selectively cooperate with a human body sensor and a household appliance controller. The personalized home management and control effect based on the user position information is achieved, and the method can be widely applied to the field of smart home.

Description

technical field [0001] The invention relates to a wireless signal positioning method and a device thereof, and belongs to the cross technical field of combining wireless network and deep learning. Background technique [0002] With the development of computer application technology, the concepts of the Internet of Things and smart home have gradually become popular, and a variety of smart home products have emerged on the market, such as: smart speakers, smart TVs, smart air conditioners, etc. Common smart home products lack For the user location perception function, although few products are equipped with infrared sensors and other equipment to perceive the human body, they are still in an independent working state, and it is impossible to realize the unified management of smart home products based on user location. [0003] At present, some scholars have proposed a technical solution based on wireless signal positioning to solve the problem of smart home products' percepti...
