Design And Implementation Of Safe-guard System For Smart Home

The smart home industry based on The Internet of things has obtained initial achievementin China as a newly emerging industry．Home safe-guard system is an important part ofintelligent residential system and the purpose of researching this system is to realize homesecurity automation, expand the function of smart home and provide people with theintelligent, safe and convenient living environment.Under the background of smart home，the thesis designs the smart home safe-guardsystem based on the wireless network technology and embedded technology by combining theintelligent safe-guard system with wireless sensor network technology. First, the thesisreviews the current situation, the trend as well as the necessity of smart home security systemsand compares and analyzes the traditional home safe-guard system and smart home safe-guardsystem. Second, the thesis explores the functions and demands of the home safe-guard system,summarizes the two basic functions of the system, local control function and end controlfunction. The thesis then proposes the whole designing scheme of hardware and software.Third, the process of the implementation of each module of the hardware is explored, whichincludes main controller, peripheral circuit, sensor module， wireless transmit/receivemodules，GSM message sending module, LED module, etc. Fourth, the thesis explores thedesign and implementation of the software of the system, including the sending messageprocedure, safety inspection procedure, LCD procedure, the key control program, etc.Through the testing, it can be found that the system can achieve the intended functionsand have a lot of advantages, such as reliable communication, strong real-time, low powerconsumption and low cost, so that it will have a bright future of market application.
