Abstract

The invention discloses a positioning method, a positioning device and a computer readable storage medium, and relates to the field of wireless communication. The positioning method comprises the following steps of determining a satellite coverage function according to a reference station variable and the number of base stations to be selected, wherein the reference station variable represents whether the base station to be selected is used as a reference station or not; according to the reference station variable, and the time period during which a satellite can be observed by each base station to be selected, determining a satellite visibility function; determining an optimized objective function according to the satellite coverage function and the satellite visibility function; and determining the to-be-selected base station serving as a reference station when the optimized objective function value is the maximum, so as to carry out positioning according to the determined referencestation. Therefore, modification and upgrading can be carried out on the basis of an existing base station, so that the positioning function is achieved, and the positioning precision is improved on the basis that the station distribution cost is reduced as much as possible.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a positioning method, a positioning device and a computer-readable storage medium. Background technique [0002] At present, the rapid development of the sharing economy has brought a lot of convenience to people's life, but also caused some troubles. Taking shared bicycles as an example, since random parking will cause congestion to traffic and pedestrians, a large number of staff are required to standardize the parking of shared bicycles that are randomly parked, resulting in a substantial increase in labor and financial costs. [0003] In order to solve this problem, it is necessary to accurately locate shared bicycles, and use incentive measures to enable users to park in a standardized manner. A GPS (Global Positioning System, Global Positioning System) module and a wireless communication module are usually installed in the shared bicycle lock. Due to the limi...
