With the rapid development of Internet of Things (IOT) तकनीकी, the demand for high-precision indoor positioning is increasing. The FSC-BP1000DN, as an intelligent beacon device based on a low-power Bluetooth chip (संवाद DA14531) and incorporating advanced Angle of Arrival (एओए) positioning technology, is redefining the accuracy standards for indoor positioning.

 

Traditional Bluetooth beacons typically offer only area-level location awareness. तथापि, by incorporating AoA technology, the FSC-BP1000DN achieves sub-meter high-precision positioning, providing unprecedented location service capabilities for various indoor scenarios.

 

System architecture design

Terminal layer: The FSC-BP1000DN beacon serves as the signal source and utilizes the DA14531 low-power Bluetooth chip to ensure stable operation over an extended period. The device supports NFC functionality, facilitating quick configuration and on/off control.

Positioning layer: Deploy Bluetooth positioning base stations that support AoA (Angle of Arrival) functionality. These base stations are equipped with antenna arrays, enabling precise measurement of signal arrival angles.

Platform layer: The positioning engine processes angle information through advanced algorithms and combines multi-base station data to achieve precise triangulation.

Application layer: Provides users with a visual management interface and API interface, supporting the integration of various business systems.
