Community Home Intelligent Guard System Based On Internet Of Things

With the aging of our population and the implementation of family planning in China,our country emerged a large number of empty nest family, and the elderly accounted for a large proportion of the empty nest families. In the unattended condition, because the elderly infirm or forgetfulness ,the elderly of empty nest family often can not timely response and deal with some hidden danger that may threat to life safety, such as the fall, bedridden patients for chronic illness ,kitchen fire and gas leakage in daily life, will cause the corresponding damage to health and safety Empty Nester, especially when the damage occurred after the failed to timely find and rescue, often lead to more serious consequences.In addition to someone in the family nursing,when the elder falling, long-term bed condition,can timely detect and giving care to prevent more serious consequences. This paper is designed to Internet related technology, hardware and software design of intelligent guard system, realizes to the elderly and function, to alleviate the family and social burden.For the design of the community home intelligent guard system implementation process,at first this paper analyzes the background of the aging of our population and family of the empty nest elderly in danger, and after no one found easily in the home, the design community home intelligent watch system. And the analysis of the situation of the elderly intelligent monitoring at home and abroad. Secondly, introduces the overall design and system uses classification architecture, mainly divides into three parts: detection, centralized control and supervision, and the three part isto be completed by the functions are introduced.The Internet related technology and sensor technology in wireless sensor networks, Zigbee technology, GSM network technology, micro controller technology as the basis to realize the hardware circuit system design, is designed to complete the wireless fall detection module,wireless liquefied gas detection module,wireless temperature detecting module, pyroelectric wireless detection module and concentration the control module. And fall detection algorithmused for fall detection module detects part of design, analysis and combining with the data curve is proposed fall detection algorithm new,validated by the experimental results.Finally, the software design of the system, set up the Zigbee network, and the network number after each module added to the network, the module to the suspicious datainformation in the detection when the alarm bell and the wireless transmission of information out, complete information transmission equipment and equipment and facilities,the world.In the software and hardware of the whole system design,simulation,thefall within the specified time, the temperature is too high, not activities,module detects the abnormal status and alarm, in no release after the information through the internal network to the central control module and display on the LCD screen, and through the GSM short message to the supervision of people send help information. The utility of the system is tested, and the subsequent expansion of system.
