Title:

SMART BALL-GROUND SYSTEM AND DATA ACQUISITION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2016/206412

Kind Code:

A1

Abstract:

A smart ball-ground system and data acquisition method thereof, comprising a smart ball (10), several wearable devices (20), several positioning base stations (30), a gateway (40) and a server (50). A wired or wireless connection exists between the positioning base station (30), the gateway (40) and the server (50). The smart ball (10) is provided therein with a first UWB tag (11). The wearable device (20) installed with a second UWB tag (21). The positioning base station (30) is provided with a UWB transceiver (31), a microcontroller (32), a clock (33) and a data communications device (35). The microcontroller (32) receives information sent from the smart ball (10) and the wearable device (20), adds a timestamp from the accurate clock (33) installed in the UWB transceiver (31), and sends the same to the gateway (40). The clock (33) is for adding a corresponding timestamp to data from other movement or physical indications. The server (50) receives information uploaded by the gateway (40) and calculates the position and motion trajectories of the smart ball (10) and the wearable devices (20) by a time difference positioning method. The data acquisition method precisely acquires various motion data of each of the smart ball (10) and players wearing the wearable devices (20), realizing motion positioning and trajectory tracking, and can be used as a basis for data analysis or further training for athletic training or competitions.
