Research And Implementation Of Wearable Body Posture Monitoring Device Based On TI CC2540

The algorithm of wearable body posture monitoring equipment has certain universality can be widely used in medical, industrial construction, the research of Unmanned Aerial Vehicle, human-computer interaction, virtual reality and other popular areas. This topic has high value of research and practice, involving ability in many aspects of the investigation of mechanical, electronic, spatial mathematical modeling.It is systematic and practical.Therefore, We need to design and achieve a new wireless wearable body attitude posture monitoring system,the equipment is easy to wear and can real-time acquisition user of posture posture,movement,motion gaming of data.The system can transmit the body posture information to the mobile client app for data processing and display by low power Bluetooth 4.0 protocol.On one hand it can prevent incorrect sitting posture of body disease, on the other hand you can play motion gaming for entertainment function.Firstly, the dynamic threshold model is established based on the three axis acceleration data by LIS3 DH,which is used to drive the vibration of the micro vibration motor when the human body Posture Monitoring is not correct. I design the corresponding hardware circuit and software algorithm in this project,and the algorithm model is explained.To ensure the project can be realized.Then, acceleration of collected data to be extended applications, with pedometers the implementation principle, achieve the record step, calculating the function expansion of the distance, calories and other functions.Secondly, the hardware system acquisition of the relevant data through the low power Bluetooth 4.0 protocol transmit to the mobile phone APP, with the development of the motion gaming to drive the movement of characters, so as to achieve the purpose of physical exercise.Finally, I complete the test of body posture monitoring and step function, the step function can further optimize the efficiency of the implementation of the algorithm; for the body posture monitoring can be further extended by the sensor of gyro, using quaternion perfect recognition and detection algorithm of integrity and scalability.
