技术问答

SKYLAB is a Chinese manufacturer of Bluetooth Beacons. SKYLAB has developed an active Bluetooth positioning and navigation system. The positioning system adopts a high-precision Bluetooth positioning engine algorithm and a low-power beacon positioning base station. Its positioning accuracy is within 2 meters. And it can provide a variety of mobile terminal high-precision indoor positioning. The Bluetooth system has functions such as real-time positioning, path planning, voice navigation, and reverse car search. Customers can integrate it into the APP.

Active Bluetooth Positioning System Architecture

SKYLAB's active Bluetooth positioning system is also called a terminal-side Bluetooth positioning system. It is composed of intelligent terminal equipment and Bluetooth ibeacon. Terminal devices include Android and iOS mobile phones, tablet computers, etc. The system block diagram is as follows.

The principle of the active Bluetooth positioning system is to determine the relative position between the Bluetooth host and the ibeacon through the RSSI value.

(1) Deploy the Bluetooth ibeacon in the positioning area. Generally, at least 3 ibeacons are required. ibeacon will broadcast a data packet to the surroundings at a certain time.

(2) The terminal equipment enters the signal coverage of ibeacon. The device will scan and receive the data packets broadcast by the Bluetooth ibeacon. The packet includes the MAC address and signal strength RSSI value.

(3) The customer can mark the current location on the map of the terminal device through the positioning algorithm and map of the mobile phone.

Bluetooth positioning system engine algorithm

(1) Customers can integrate the Bluetooth positioning system engine algorithm into the APP. Then you can use location services through the APP.

(2) SKYLAB provides offline/online SDK options. Offline SDK does not require a network connection and consumes no data.

(3) The SDK capacity of the Bluetooth positioning system engine algorithm is small, about 50KB, and the integration is simple.

(4) Developers can use it flexibly and support cycle settings and log output settings.

(5) The positioning algorithm adopts K-best, k-means, and self-developed algorithms. It can perform intelligent matching and support optimization algorithms such as Kalman.

Advantages of Active Bluetooth Positioning System

SKYLAB's active Bluetooth positioning system has the characteristics of high precision, a large number of users, and high concurrent access. It supports intelligent route navigation, software modularization, and open architecture design. The ibeacon device has low power consumption and supports long standby time. The system is easy to deploy, easy to maintain, and supports mobile app access.
