Abstract

The invention discloses a Bluetooth-based vehicle searching method. The method mainly comprises the steps of: establishing a first rectangular coordinate system; ranging to obtain the first distance between a mobile terminal and a first Bluetooth, the second distance between the mobile terminal and a second Bluetooth and the third distance between the mobile terminal and a third Bluetooth; calculating to obtain the virtual coordinate of the mobile terminal in the first rectangular coordinate system; establishing a second rectangular coordinate system by taking the first Bluetooth as the origin and the south direction where the first Bluetooth is as the second X-axis forward direction; obtaining the included angle between the first X-axis forward direction and the second X-axis forward direction; calculating to obtain the practical coordinate of the mobile terminal in the second rectangular coordinate system; calculating to obtain azimuth information of the mobile terminal in the second rectangular coordinate system; and sending the azimuth information and the first distance to the mobile terminal. Three Bluetooth devices are arranged at different positions of a vehicle; and thus, without other auxiliary positioning equipment, a vehicle owner can rapidly find out the vehicle.

Description

technical field [0001] The invention relates to the technical field of wireless positioning, in particular to a Bluetooth-based car-finding method, a vehicle-mounted Bluetooth device and a storage medium. Background technique [0002] Current mobile positioning technologies mainly include: satellite positioning and network positioning. Satellite positioning is expensive and users need additional equipment support; network positioning requires the deployment of sufficient base stations to provide stable signal quality. [0003] As the phenomenon of difficult parking in cities becomes more and more common, most new buildings incorporate parking lots into construction planning, and the area of ​​parking lots is in a steady increase trend, and most of the parking lots are located underground, resulting in parking Poor GPS and network signals in the field make it difficult for car owners to find their vehicles in a short period of time in the parking lot, resulting in low efficie...
