| With the development of society,as a country with a large population,the problem of aging has become increasingly serious.There are more and more social problems arising from it.Young people are busy with work and have no time to take care of the elderly.More and more elderly people will go out of their homes and enter the nursing home to spend their old age.At the same time,the national and local governments have successively introduced policies and guidelines for accelerating the development of the cause of aging.Nursing homes,which are the main components of institutional elderly care,will develop rapidly.Nursing home nursing staff's business level is uneven,and nursing homes cannot be fully managed,and other issues have become key factors restricting their development.The current nursing home management system is mostly concentrated on the business management level,and the lack of physical health monitoring for the elderly causes potential management risks and hidden safety hazards in the nursing home.In order to solve the above problems,this article designs a set of IoT nursing home management system based on Bluetooth Mesh technology and meeting the nursing care management needs of nursing homes.This research of this paper can be divided into two parts: the software designing and the hardware designing.In terms of hardware,taking Bluetooth Mesh wireless communication technology as the research object,we designed three hardware devices based on Bluetooth Mesh bracelet,Mesh relay node,and Mesh routing.The bracelet is used as the unit node of the pension management system;the heart rate sensor and the temperature sensor are used to collect the health status of the elderly;the acceleration sensor is used to capture the movement status,sleep status and fall action of the elderly.Mesh relay nodes and Mesh routers,as auxiliary devices of the bracelet,provide data transmission and personnel positioning functions.In terms of software,on the one hand,the business management system that meets the daily operation of the nursing home is designed by referring to the traditional management system of the nursing home;on the other hand,based on the hardware equipment,the nursing management functions such as positioning,movement detection,fall detection,emergency call,physiological health monitoring and other functions..Finally,after the completion the system software and hardware development,a simulation test platform was set up based on the actual nursing home environment to debug the overall business functions,software and hardware functions of the system.The functions of Bluetooth Mesh network communication,indoor personnel positioning,heart rate and blood oxygen detection,surface temperature monitoring,and fall detection were tested.The stability and implement ability of the system were verified,and shortcomings in the system design were found.At last,we made a summary of the design. |
