Claim One:
1. A multi-person pose recognition system, comprising: a body pose detection module comprising: a triaxial accelerometer for measuring an acceleration signal of a human body; a Zigbee chip having a transmit/receive buffer, a voltage converter and an antenna, and providing data of on-line intensity and connection quality to acquire on-line statuses among nodes; and a microcontroller having a plurality of A/D converters for converting an analog signal of the triaxial accelerometer into a digital signal, and an interface disposed between the triaxial accelerometer and the Zipbee chip to initialize the triaxial accelerometer, control a sleep state of the triaxial accelerometer and select a measuring range of the triaxial accelerometer, and for controlling the transmit/receive buffer of the Zigbee chip to read or write buffered data or respond with chip status information; and a Zigbee wireless sensor network (WSN) development board serving as a receiving end of a Zigbee WSN, bundled with a plurality of body pose detection modules to construct the Zigbee WSN for mutual communication between the body pose detection modules.
