Embodiment Construction

[0044] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0045] Such as figure 1 As shown, the rail traffic positioning and navigation method based on bluetooth positioning of the present invention comprises the following steps:

[0046] Step 101, draw a scene map according to the application scene of rail transit;

[0047] Specifically, in step 101, it is necessary to draw a scene map according to the actual application scene of rail transit (i.e., subway). In the map drawing stage, the public scenes in the indoor environment of rail transit (including but not limited to toilets, customer service centers, etc.) will be used as Map POI (Point Of Interest, point of interest) information;

[0048] In addition, in step 101, when drawing the scene map, the road network data of the application scene of the rail transit is also fused, that is, the road network of the on-site indoor envi...

Abstract

The invention discloses a rail transit positioning and navigation method and system based on Bluetooth positioning and a rail transit positioning and navigation method. The rail transit positioning and navigation method comprises the following steps: S1, drawing a scene map according to an application scene of rail transit; S2, installing a plurality of Bluetooth beacons in an application scene ofthe rail transit; S3, collecting an RSSI signal of the Bluetooth beacon on site through the intelligent terminal; and S4, positioning the intelligent terminal according to the acquired RSSI signal, and marking a positioning result in the scene map. According to the invention, the plurality of Bluetooth beacons are installed in the application scene of the rail transit, and the intelligent terminal is positioned through the Bluetooth positioning algorithm, so that the positioning precision is improved, and more accurate indoor positioning of the rail transit is realized.

Description

technical field [0001] The invention relates to the field of Bluetooth positioning and navigation, in particular to a method and system for rail transit positioning and navigation based on Bluetooth positioning. Background technique [0002] Urban rail transit has become the main means of transportation for the daily flow of people in the city. Rail transit is currently the main means of travel for urban public transportation. Various services of rail transit have attracted more and more attention from passengers. In the increasingly prosperous rail transit stations, some Problems are also appearing more and more frequently. These problems mainly include: [0003] 1. No public facilities found [0004] Different rail transit stations have different layouts, resulting in different locations of some public facilities. Even for some public facilities, some stations are inside the gates, and some stations are outside the gates. Signage is often not enough to meet the needs. ...
