Design of community intelligent pension system based on Internet of Things
At present,the traditional family pension model has been difficult to meet the increasingly prominent needs of human and medical resources brought by aging.Therefore,this paper proposes a home-based and community-based community elderly care system scheme,which is divided into two parts:human wearable devices and community service terminals.The wearable device collects vital signs data through modules such as Micro-Electro Mechanical System sensors IMU901 and MAX30102,and transmits it to the microcontroller STM32 for processing through the interface circuit.The microcontroller STM32 uses GSM technology to realize automatic alarm function,and transmits vital signs data and help in-formation to the community service terminal through Zigbee technology.Community service terminal uses Java language development,adopts the model of front-end and back-end separation,designs the hierar-chical processing system of help event,effectively alleviates the shortage of community staff.In the data processing,Mahony quaternion is used to solve the attitude algorithm,which makes up the disadvantage of the Euler Angle algorithm which is easy to produce universal-joint deadlock.The experiment shows that the system has high accuracy,strong reliability and fast response,and achieves the expected effect.
