Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0041] The Bluetooth positioning system is the product of the perfect integration of Internet of Things technology and mobile Internet technology. The bluetooth indoor positioning system of the present invention is based on low-power bluetooth technology, and realizes precise positioning functions through bluetooth positioning beacons, intelligent terminals and servers.

[0042] Bluetooth positioning beacons: Bluetooth positioning beacons use low-power Bluetooth technology to periodically broadcast wireless signals with device IDs into the space. The Bluetooth positioning beacon uses the 2.4GHz public frequency band, which has the ability of frequency hopping and anti-interference; when broadcasting, the Bluetooth positioning beacon uses 3 channels, the frequency is: 2402MHz, 2426MHz, 2480MHz. Broadcast period: 10ms to 10s can be set; power c...

Abstract

The invention discloses an intelligent terminal for indoor positioning and a bluetooth indoor positioning system, and relates to a lower-powder bluetooth technology and an indoor positioning technology. The intelligent terminal disclosed by the invention can sense a broadcast signal of a bluetooth positioning beacon in a space, an intelligent terminal off-line module and the intelligent terminal on-line module adopt a stable Beacon precedence algorithm, an optimization k-nearest neighbor method and a kalman filtering algorithm to position the intelligent terminal. The bluetooth indoor positioning system disclosed by the invention comprises the bluetooth positioning beacon, the intelligent terminal and a server; the bluetooth positioning beacon adopts the lower-powder bluetooth technology to broadcast a wireless signal with an equipment ID periodically in the space. The server mainly is used for providing map and database resource download service and positioning monitoring service for the intelligent terminal. The invention has a very high practical value on indoor positioning, and can be used for improving the positioning accuracy and correction on indoor positioning.

Description

technical field [0001] The present invention relates to low-power bluetooth technology, indoor positioning technology and the Internet of things plus Internet technology field, especially to an intelligent terminal for indoor positioning and a bluetooth indoor positioning system, which has high practical value for indoor positioning and can improve indoor Positioning precision and accuracy. Background technique [0002] The existing Bluetooth positioning technology uses the mapping relationship between the signal strength value and the actual distance for positioning. Because the signal strength is greatly affected by environmental factors (temperature, humidity, physical occlusion, etc.), the actual distance value calculated by it is also Extremely unstable and inaccurate. Therefore, the disadvantages of the existing Bluetooth positioning technology are large positioning errors, low precision, and weak stability. Contents of the invention [0003] The technical problem ...
