Research Of Indoor Monitoring System For Elderly Based On Multiple Sensors

According to Chinese latest census figures,it shows the number of the old people who is more than 60 years old already beyond 15% of the whole population.From which,we can see the aging population trend is obvious but the elderly are lack of nursing resources.The medical practice shows the elderly need professional treatment in time when some emergency happened to them,or else their life will be in danger.To find the emergency happened to the elderly in time,meanwhile to improve the working efficiency of the nursing people,the study of real-time monitoring for the elderly raised more and more attention.This paper puts forward an indoor monitoring system based on multiple sensors to meet the needs of real-time monitoring for the elderly indoor,through which,the nursing people will receive information in time when some emergencies happened to the elderly indoor.Firstly,it introduces the research status on indoor monitoring systems and summarizes its existing disadvantages.Secondly,it starts with the construction design and communication way choosing of the whole indoor monitoring system,explains the sub-system's composition structure and hardware circuit design.Thirdly it describes the detective methods for all sub-systems,meanwhile it brings in the finite state machine(FSM)to check the changing status of the sensors.At last,it conducts a series of experiments based on the previous mentioned detecting methods,and by contrast,it carries out tests under different test parameters and the test environment to prove the effectiveness of the detecting methods and the rationality of the equipment construction design.This system has many advantages such as low cost,easy to be installed,very convenient to be used and good detective effect,which could be widely used for improving the quality living life of the elderly.
