Research And Design Of Sitting Posture Monitoring Robot

Working and learning in incorrect sitting position for a long time is not conducive to good health,which increases the incidence of hunchback,scoliosis,Work-related musculoskeletal disorders and so on.In order to reduce the risk of disease caused by sitting posture.Based on the analysis of different sitting posture,a set of sitting attitude monitoring robot based on pressure sensor is designed in this paper.In this design,Arduino Mega 2560 is used as the hardware control core of the robot system,which includes three monitoring functions: sitting position monitoring,lighting environment monitoring and sitting time length monitoring.The main research contents are as follows:(1)The development status and future prospect of intelligent sitting attitude monitoring equipment are analyzed and studied,and the monitoring method and sitting attitude recognition method of sitting attitude monitoring robot designed in this paper are put forward.It is determined that the sitting attitude monitoring robot includes three monitoring functions: sitting posture monitoring,lighting environment monitoring and sitting time monitoring.(2)The hardware design of the sitting posture monitoring robot and the solid model are processed.The specific work is as follows:(?)The three-dimensional model of the sitting posture monitoring robot is built by using SolidWorks software,and the static finite element analysis and the first six order modal analysis of the sitting posture monitoring robot are carried out by using Ansys Workbench software according to the four sitting postures.(?)Arduino Mega 2560 development board is selected as the control element of the sitting position monitoring robot,and the control circuit of the sitting position monitoring robot is built by selecting the corresponding sensors and HLK-M35 wireless module according to the function.(3)According to the monitoring function of the sitting posture monitoring robot,the software is designed,which enables the sitting posture monitoring robot to realize the basic function of real-time monitoring,and completes the serial communication and wireless communication between different software.The specific work is as follows:(?)Using Arduino IDE software and SCoop multi-threading to complete the design of the lower computer of the sitting posture monitoring robot.(?)Processing IDE software and Android Studio software are used to design two kinds of software at the same time.Processing PC monitoring program APP PC software is designed for different users.(4)The modules of the robot are tested by experiments.The experimental results show that each module can monitor normally,and at the same time,the pressure values of the activated position sensors under 50 groups of four sitting postures are measured.Finally,based on Pearson correlation coefficient theory,data processing and analysis of 50 groups of pressure data measured in the experiment were carried out to verify the correlation between height,weight and sensor pressure.The results of data analysis showed that body weight had a great influence on the magnitude of pressure at the activation site.
