Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0034] A WiFi positioning method for shared bicycles based on three-dimensional calibration, wherein a WiFi positioning module is installed on the shared bicycles, and the positioning method is specifically as follows:

[0035] Before the shared bicycles are launched, the AP three-dimensional calibration is carried out, and the AP information database is established. Specifically:

[0036] S1: if figure 1 As shown, the AP signal detection device is first installed at the same height H as the WiFi positioning module. The AP signal detection device detects the AP signal strength and MAC address in the area, selects a strength, and then uses GPS to calibrate a corresponding strength. Coordinate position (x1, y1), and then calibrate two positions (x2, y2) and (x3, y3) accor...

Abstract

The invention relates to the field of shared bicycle communication positioning, and provides a shared bicycle WiFi positioning method based on three-dimensional calibration. The method comprises the following steps: before a shared bicycle is put into operation, performing AP (Access Point) three-dimensional calibration and establishing an AP information database; after the shared bicycle is put into operation, acquiring AP positioning information in an area by a WiFi positioning module, and transferring the acquired AP positioning information to a processor; processing the AP positioning information by the processor and controlling a GPRS module to upload the processed information to a server; calculating the current position of the shared bicycle by the server according to the received information and the AP information database; and responding to a positioning request of a display client by the server, performing data screening and calculation according to the positioning request, and transmitting calculated position information to a positioning display client in real time. According to the shared bicycle WiFi positioning method based on the three-dimensional calibration provided by the invention, when the AP information database is established, only a database of AP label number coordinate information in the area is established, thus the workload is saved and the load of the server is reduced.

Description

technical field [0001] The invention relates to the field of shared bicycle communication positioning, in particular to a shared bicycle WiFi positioning method based on three-dimensional calibration. Background technique [0002] At present, there is a blowout development of shared bicycles, among which the positioning method of shared bicycles is the core competitive factor and limiting factor of shared bicycles. Most of the existing shared bicycles use GPS Internet of Things positioning solutions. Power management method for vehicle-mounted GPS devices" and other patented technical solutions. However, through the research on GPS positioning, How Chuan et al published the research on vehicle GPS precise positioning technology in the "urban canyon" environment. That is, the positioning requirements in this case in the city cannot be met. Based on the popularity of WiFi chip-related hardware devices, the research of WiFi positioning algorithms, such as: three-sided positio...
