Design And Implementation Of Smart Home Wireless Security System Based On CC3200

With the rapid development of economic society,the smart home based on the technology of Internet of Things makes people gradually turning to digital and networked intelligent society.Security system is an important component part of smart home,it goes in the direction of front-end integration,digitized video,networked monitoring,and integrated system.With WI-FI technology maturing,it is gradually widely used in high-speed short-range wireless network and gradually intrude into the field of wireless sensor networks.Combining the WI-FI technology with intelligent household,it makes the family security more reliable,and more convenient,home broadband has become a part of the high quality of life in the future.In this paper,the design of smart home wireless security system starts from the low power consumption,low cost,convenient installation.The design combines the security module with the first single chip wireless microcontroller Simplelink WI-FI CC3200 of Texas Instruments as the core,and achieves the hardware design and software design,then completes the realization of the function of the home security system.The hardware design includes the A/D conversion circuit,data collection and communication interface circuit.On the software side,it realize the embedded WI-FI protocols,and then programs the sending and receiving procedures of information collection.Finally mobile web side achieves real-time monitoring and cell phone APP conducts real-time monitoring,including infrared detection over human body and inflammable gas detector.And then it can control appliance switch system through the home network and cloud platform.The main innovation point of this study is the latest research and development of TI company's first single chip wireless microcontroller SimpleLink WI-FI CC3200 used in the design of smart home,and the use of Yeelink clouds and APP on mobile terminal real-time monitoring and control of electrical appliances for the family.CC3200 as one of the biggest bright spot,is the first in the industry that has a built-in WI-FI connectivity of the single chip micro controller unit(MCU),SimpleLink CC3200 device integrates high performance ARM architecture C-M4 wireless MCU,the application of micro controller,WI-FI network processor and power management subsystem.The thesis researches on CC3200 specifications and technicalcharacteristics of parameters,the design of the corresponding peripheral circuits,in home network as the background,combined with the cloud platform,based on the intelligent household hardware and software design of wireless security systems,and complete the application of smart home wireless security system based on CC3200 implementation,including wireless video monitoring system,the human body infrared induction security alarm system,combustible gas monitoring alarm system and construction of integrated family intelligence system,mobile real-time monitoring and control electrical appliances.,on the other hand,in the design,but also remove the CLOSED,let it in the LISTEN state,from the start to LISTEN to the client's connection request,avoided the operation of the active or passive open,embedded occasion,more efficient.
