Design Of Wireless Smart Lock System Based On ZigBee

With the continuous improvement of the life’s quality,peoples’ requirements for home securityare higher and higher,ordinary mechanical locks become more and more powerless for preventingmodern burglary.Moreover, the strength of security measures are directly reflects an individual’sidentity and status.Electronic smart locks which using a new generation identificationtechnology(including passwords, fingerprint, iris, etc) for access control greatly improve homesafety at the same time new problems began to emerge. As the door is attacked, users have no wayto know about it,directly led to various of thefts constantly.A wireless smart lock system based on ZigBee wireless networking has been designed.In thissystem,your smart lock is connected with the condos management through the wirelesstechnology.The open and close information of the smart lock is stored in the community’s datamanagement center and you can check the information or trace the illegal information who open thedoor. The system also support online report function which can let you find and fix the system aslong as the smart lock is off line.All of these can make sure your smart lock can run safety. Smartlocks also offers a complete real-time monitoring mechanism.Any operation of smart lock ofanyone will be obtained by you timely.This paper first of all describes the defects of existing smart lock technology and given thesuperiority of wireless smart lock based on clouds in these areas.According to the demands of smartlock system’s scheme,analysis and design the whole framework of system and furtherly provide aspecific design method. Because the request of power and cost, as well as, the advantage ofsingle-chip solution, the CC2530ZigBee SoC chip as development platform and the mesh networktopology structure are chosen at last. Application software design of smart lock system is Stresslyintroduced, including the coordinator and end device starting a network, serial interactive, networksecurity, serial API data frame, software update, etc.Finally, a comprehensive reliability of the smart lock system is measured. mainly including thefunctional testing, the distance testing of peer-to-peer communications, packet loss rate testing,power testing and network testing.Test simulates the actual work environment based on therequirements of smart locks, tracking and monitoring the transmission data real time use capturesoftware.
