Design Of Home Intelligent Access Control System Based On Cloud Platform

With the popularization and vigorous development of modern Internet of Things and other information technologies.Smart homes have gradually integrated into the daily lives of residents.Numerous smart home related products have been continuously researched and improved.As a bright product of smart home,the home access control system stands out in the new situation.Traditional access control systems usually use metal keys,access cards and digital passwords to open the door.These methods generally have the drawbacks of difficult key management,poor flexibility,low security and so on.Aiming at the emergence of problems in the traditional access control system,this paper puts forward the design scheme of the home intelligent access control system based on the cloud platform.Based on traditional access control,the solution will use access control as an entry point to add key technologies such as Internet of Things,face recognition and APP software development.Users can use the mobile phone APP to easily complete remote video monitoring and one-key unlocking,and can also give temporary visitors the right to unlock using electronic QR code keys.The home intelligent access control system is mainly composed of hardware module,cloud platform and APP software.Among them,the hardware module takes STM32F103RCT6 single-chip microcomputer as the core control unit,and uses the Raspberry Pi 3B + as a sub-control system to recognize human figures and faces.Once the Raspberry Pi 3B+ recognizes the result,it sends to the main control chip STM32 of the ARM Cortex-M3 core.The main control sends to the cloud platform through the wireless transmission module after analyzing and processing.At the same time,STM32 will receive the control commands from the cloud platform to the two steering gear,and control the door lock and pin to complete the open and close operations.The cloud platform mainly solves the problems of remote control and real-time performance in the home intelligent access control system.It can not only store the data uploaded by the lower computer,but also support APP to retrieve the cloud data and view the command operation of the lower computer.The mobile phone APP software is specially developed for the home intelligent access control system.Residents can use the mobile phone's own Wi-Fi or Bluetooth to connect devices.The operation of authentication is completed through the interactive verification of messages such as account numbers and passwords.After the authentication is completed,remote wireless control of the door lock can be realized.As the last line of defense to protect the household property of the household,the intelligent home access control system not only contains all the functions of the traditional access control system,but also overcomes the deficiencies of the traditional access control system,it also improves the convenience of family residents' life and meets current and future access control intelligence demand for development.This article completes the hardware architecture construction and software design process of the home intelligent access control system,and tests the overall function of the access control system in a real environment.The test results show that the home intelligent access control system designed in this paper can not only control the door lock remotely,but also have the capability of real-time monitoring of remote information.In the actual testing and control process,the entire access control system works steadily and has many advantages in intelligence,safety,convenience and so on.
