Underground garage vehicle search system based on Bluetooth 5.1 departure angle

Abstract

The invention provides an underground garage vehicle search system based on a Bluetooth 5.1 departure angle, and belongs to the field of precise real-time positioning vehicle search and guidance. Theunderground garage vehicle search system comprises an electronic tag, an electronic tag information reader-writer, a geomagnetic Bluetooth parking space detector, a positioning module, a Bluetooth mesh gateway, a server and a mobile phone client. The electronic tag and the electronic tag information reader-writer record and transmit license plate number of a user; the geomagnetic Bluetooth parkingspace detector detects parking spaces and transmits the license plate number information of the occupied parking space; the positioning module sends a positioning beacon to a mobile phone of the user; the gateway collects information of the license plate number of the user and the corresponding occupied parking space number and forwards the information to the server, and can notify and enable thepositioning module required for vehicle search to send the positioning beacon; and the mobile phone receives the beacon of the positioning module, pushes the current location to the server and receives a real-time vehicle search route. The underground garage vehicle search system provided by the invention uses the Bluetooth 5.1 departure angle technology to realize vehicle search, so that the required cost is low, the construction is high, the safety and reliability are good, no dependence is laid on a base station signal, and the user can quickly and accurately search the vehicle even in thecase of weak signal.

Description

technical field [0001] The invention relates to the field of indoor positioning and car-finding guidance, in particular to an underground garage car-finding system based on Bluetooth 5.1 starting angle technology. Background technique [0002] At present, most underground garages need to arrange multiple cameras to capture the parking position of the vehicle. When searching for a car, the user's parking position information is pushed to the user according to the image recognition algorithm. However, this solution has problems such as high equipment cost and complicated wiring. If you consider using Bluetooth 5.1 starting angle and Bluetooth mesh networking technology to find a car, you only need to configure a series of Bluetooth devices to realize accurate and real-time car finding in the underground garage. This solution has low equipment cost, simple construction, safety and reliability, and does not need to rely too much on base station signals. Contents of the inventi...
