Information Collection of Motion Based on Wireless Sensor Network

摘要

The health of the people is closely related to the motion of themselves. The evaluation of human motion by analyzing posture and trajectory of them, provides a scientific basis and evaluation tools of the research based on of human motion. Based on Acceleration Sensor and Wireless Sensor Networks, this paper designed the motion information acquisition system, it can collect the acceleration information of human daily movement, and provides data preprocessing carried out on the acceleration information. The lower monitor part include the ZigBee protocol component network, coordinator node to transmit and receive data, the data collection node can be free to join or leave the network.
