The Design Of The Visual Access Control System Based On The APP End Of The Mobile Phone

With the development of society,the progress of science and technology,the continuous improvement of people's living standards,in the era of digital information technology,wireless communication technology,image processing technology,intelligent home control technology and development technology of mobile phone APP is widely used in our lives,Such as visual intercom access control system.Although the market has been a lot of a wide range of visual doorbell system,but the traditional security system occupied a larger share is still a problem,caused by such systems are often fixed position and the lack of alarm device design,Users should go to a fixed position to answer when dealing with access control,so it is too much inconvenience.Therefore,designing a set of program based on the visual access control management system of mobile phone APP can control the doorbell for homeowners anywhere in the room,at any time.At the same time,the system can also achieve burglar alarm function to solve the inconvenience of the owners because of the modern district security management and making people's lives more convenient.This paper will briefly introduce the design of the visual access control system based on the APP end of the mobile phone.Combining the technical type of the current access control system and the characteristics of the wireless network technology,this paper discusses the design and implementation process of the visual access control system based on the APP end of the mobile phone.based on ARM Cortex-M4 core's STM32F407 chip as the core,it is mainly to achieve the following functions: First,the combination of the owner of the wireless response and fixed response function;Second,the mobile phone APP wireless control access control;Third,the burglar alarm and video preservation;Fourth,voice messages.In the software,we designed the next bit machine software and the APP end of the mobile phone,using Keil5 MDK as a compilation environment for embedded programdevelopment and make the peripheral circuit for unified programming and control.The APP end of the mobile phone is mainly using the Java language to design software in the Android operating system and wireless transmission through the WiFi,so as to achieve mobile phone APP wireless control access control system,and provide a platform for mobile control for the entire system.
