Embedded Intelligent Nursing Home Monitoring System

Since the 21 st century,the problem of aging population in China has intensified.Accelerating the development of aging industry to relieve social pressure has become an important problem to be solved in China.According to the survey,only a small part of the elderly are willing to take care of themselves in nursing institutions,so China's pension market is huge.In this context,in order to protect the living needs of empty-nesters,this paper mainly applies embedded technology and multi-threshold algorithm to judge falls to build an embedded intelligent nursing home monitoring system.By wearing a fall bracelet for the elderly to detect whether they fall in the nursing home,after falling,the alarm message will be displayed on the upper computer of the monitoring room.The bracelet can also detect the heart rate and blood pressure of the elderly,and display the data on the upper computer and the health status of the elderly at this time.Through various environmental sensors to detect the environmental data in the nursing home,and according to human comfort parameters,automatic control and adjustment of indoor electrical equipment.The main function of the system is divided into two parts: monitoring the physical state of the elderly and monitoring the living environment of the target personnel.On the part of the elderly health monitoring is to be measured personnel wear bracelet fall detection,combined with multiple threshold judgment fall algorithm and Zigbee technology,personnel fall whether happen for detection and alarm,and collected tester of heart rate,blood pressure in the upper machine shows that the health situation,analysis of whether related diseases,such as high blood pressure,to provide medical care and early warning measures.The part of monitoring the living environment is to set sensors in the living environment,set indoor PM2.5 concentration,temperature and humidity according to human comfort parameters,and automatically control indoor environmental parameters to ensure the comfort of the living environment.Smoke alarm device and video monitoring device were set to ensure the safety of the monitoring area.Infrared sensors were placed in the activity area of the tester to monitor and analyze the activity rules.Finally,this paper designs the embedded intelligent nursing home monitoring system,including multi-threshold fall algorithm,fall alarm and heart rate and blood pressure monitoring bracelet hardware and software design,indoor environment monitoring system design,terminal controller design,uppercomputer monitoring design.Through functional testing,experimental data analysis and reliability testing,this system shows that it can monitor and timely respond to the elderly's accidental fall,and its reliability is high.The application of the system can provide the elderly with a safe and comfortable living environment.
