Problems solved by technology
The basic principle of positioning technology based on signal strength is to calculate the distance between the signal receiver and the signal source based on the strength of the received signal. At present, the triangle strength algorithm is usually used, but the accuracy of the triangle strength algorithm is not high, and the positioning error rate is high. , it is difficult to meet the indoor positioning requirements, especially for floor positioning

Embodiment Construction
[0056] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0057] like figure 1 as shown, figure 1 It is a schematic flow chart of a preferred embodiment of the floor positioning method of the present invention.
[0058] In this embodiment, the floor positioning method includes:
[0059] Step S10, regularly acquire the altitude detected by the mobile terminal, and compare the acquired altitude with the preset initial altitude to obtain the altitude difference;
[0060] The mobile terminal (for example, a mobile phone) detects the altitude through its own GPS module. After the electronic device starts the positioning monitoring, it regularly (for example, every 10 seconds) obtains the altitude detected by the mobile terminal. After each acquisition of the altitude, it will...

The invention discloses an electronic device, a floor positioning method, and a computer-readable storage medium. The method includes: regularly acquiring the altitude detected by a mobile terminal, and comparing the acquired altitude with a preset initial altitude to obtain an altitude difference; When the height difference exceeds the preset altitude threshold, the device signal data of multiple wireless devices detected by the mobile terminal at the current location is received, and a feature vector is generated according to the device signal data; the feature vector is input into the pre-trained floor positioning classification model, Predict the floor of the mobile terminal; verify whether the predicted floor is reasonable; if the verification is reasonable, determine the predicted floor as the floor of the mobile terminal. The technical scheme of the invention reduces the probability of floor positioning errors and ensures the accuracy of floor positioning.
Description
technical field [0001] The invention relates to the field of wireless positioning, in particular to an electronic device, a floor positioning method and a computer-readable storage medium. Background technique [0002] At present, most common WiFi indoor positioning technologies are based on IEEE802.11b / g protocol wireless local area network (WLAN) signal strength positioning technology. The basic principle of positioning technology based on signal strength is to calculate the distance between the signal receiver and the signal source based on the strength of the received signal. At present, the triangle strength algorithm is usually used, but the accuracy of the triangle strength algorithm is not high, and the positioning error rate is high. , it is difficult to meet the indoor positioning requirements, especially for floor positioning. Contents of the invention [0003] The main purpose of the present invention is to provide an electronic device, a floor positioning met...
