Research And Implementation Of Smart Security Lock Based On Bluetooth

Bluetooth lock is a daily hardware.With the state of further deepening of the reform of manufacturing industry,internet plus strategy further,China’s cylinder industry has achieved rapid development.Especially the smart lock industry has become the main force.Forcing lock industry transformation development.Not only in the country has achieved a higher share of worldwide and praise,to lead the global development trend of intelligent lock.However,the price of smart lock has always been high,inconvenient installation,upgrade of traditional locks and other human and material resources into shortcomings.The smart lock core industry to find its potential.Smart locks better adapt to the global wave of intelligence interpretation.The adjustment strategy of national industrial policy helps to solve the development of the industry and the reform problems.Adapted to the technological requirements of transformation and upgrading of the lock industry in the new era.Smart cylinder research is of great significance.Through in-depth investigation of the development status of smart lock core products at home and abroad.Combined with the advantages of each manufacturer technology,this paper presents a Bluetooth-based smart security lock core research.Analyze hardware requirements,considering the reliability and product of the system,the hardware of the lock end,the hardware of the gateway and the key with ID are designed.The working process of the system is analyzed.The software design includes the Bluetooth program on the core side,the gateway side main MCU program,the gateway side Bluetooth program,the gateway side Wi Fi configuration,the mobile terminal program and the server program.The program work process is unified planning,well connected,the realization of the mobile terminal APP unlocking,suspicious unlocking monitoring and reminding,cloud intelligent takeover and other functions.The system is developed by the process of product design.The technology is complex,the cost of replication is high,the mass production price is low,and it has triple verification.Bluetooth gateway realizes dual design of wired and wireless communication.The power consumption of Bluetooth core less than 1u A.According to different application needs,we can tailor the functions of the system and compromise the safety and convenience.It is suitable for many occasions.This article introduces the most complex three-heavy lock core.At the same time,the antenna design of the Internet of things system is introduced in detail.Based on the analysis and summary of the problems occurred in the design,the reliability design method of the product is given,which accelerates the product application step.
