Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] combine figure 1 and figure 2 As shown, a Bluetooth positioning method based on indoor map information includes the following steps:

[0027] S1, import the planar map of the indoor area into the Bluetooth location server, mark the room wall and door information through the page, submit the marked information to the background database, and store it in different sub-areas in the form of vertex arrays. Among them, a, b, c, d, e, f, and g are each sub-area respectively, and the surrounding area around each sub-area is a wall, and the "line segment" set on the "wall" is a "door".

[0028] Specifically, the information of the room walls in the area is described in the form of polygon vertices. For the convenience of subsequent calculations, th...

Abstract

The invention discloses a Bluetooth positioning method based on indoor map information. The method comprises the following steps of S1. importing a flat map of an indoor region into a Bluetooth position server, and labeling a room wall and door information; S2. receiving Bluetooth tag data and then sending the Bluetooth tag data to the Bluetooth position server by a Bluetooth positioning base station, and calculating spatial position coordinates of each tag by the Bluetooth position server through an RSSI positioning principle; S3. determining whether the Bluetooth tag crosses a sub-region through the door according to spatial position coordinates of the Bluetooth tag and stored indoor map information, and correcting coordinates of the Bluetooth tag; and S4. asking the Bluetooth position server for the spatial position coordinates of the Bluetooth tag and information of a sub-position in which the Bluetooth tag is by an indoor position application layer server according to service userequirement. The invention further discloses a Bluetooth positioning system corresponding to the Bluetooth positioning method. The method effectively solves a problem of 'wall penetration' in indoor Bluetooth positioning.

Description

technical field [0001] The invention belongs to the technical field of smart city and indoor positioning, and in particular relates to a Bluetooth positioning method and system based on indoor map information. Background technique [0002] With the development of wireless communication technology, emerging wireless network technologies, such as WiFi, ZigBee, Bluetooth and ultra-wideband, have been widely used in offices, homes, factories, etc. Bluetooth positioning technology has been widely used in many fields due to its universality, simplicity, low power consumption and low cost. Bluetooth positioning is based on RSSI (Received Signal Strength Indication, signal field strength indication) positioning principle, using advanced angle detection technology, which has the advantages of high precision and strong anti-interference ability. [0003] The positioning accuracy of Bluetooth is between 0.3m and 0.5m. In the actual application of indoor positioning, when the Bluetooth...
