Home Health Monitoring System Based On Internet Of Things

With the intensify situation of the increasing number of the elders and the impact exerted by one-child policy,numerous empty-nest elderly families emerge in the temporary society.In the circumstance which the children are busying their own work,the elders that live alone and in weak physical can not be copy with the emergency,such as trumbing,being bedridden,the kitchen fire and so on,which get rise to the threaten to the elders.Meanwhile,lots of chronic disease such as cardia-cerebrovascular disease can lead to a severe consequence if can not be remedied on time.Therefore,In this paper,through the short distance wireless communication technology,embedded technology,the Internet communication technology and the comprehensive application of GSM network technology,a home health monitoring system is designed based on Internet of things to realize the monitoring function to the elders,therefor the pressure on children and society is relieved.Firstly,according to demand of the system function,the overall design of the sys tem is proposed,namely,wireless detection layer,layer embedded gateway and remote monitoring,and the function of each part is analysed.Secondly,module hardware is designed in the layer of the wireless testing section,such as temperature,human activities,fall,fire detection.Through monitoring the data of Zigbee wireless communication technology to achieve the purpose of detecting,sending,receiving,processing and other functions including writing the code of driver detection module and data transmission program.In the design of embedded gateway,the function of peripheral circuit design is completed based on S3C2440 core board,and the Bootloader and the Linux kernel are transplanted in the platform to make the root file system and establish a development environment of embedded systems.Though writing the code of a serial port,the data from Zigbee coordinator is put into the database in the embedded gateway in real-time.Finally,in the design of remote monitoring,Boa embedded Web server and the SQLite embedded database is transplant into the file system of the Linux system.In the B/S mode,through the HTTP protocol,CGI interface,the using of HTML language,the remote browser can access to Boa in embedded gateway server,and the data in the database can be called to the remote browser to reveal the function of remote monitoring.At the same time historical data can be checked in order to diagnose chronic diseases in the trend of the changing data.In addition,though the TC35 GSM SMS module,the emergency situation can be alarmed in the dangerous situation.
