The Design And Implementation Of Intelligent Visual Electronic Doorbell System Based On ARM

In recent years,with the continuous development and expansion of smart homes,intelligent doorbells,which is an important part of smart homes,have also been greatly developed.From the current situation,smart doorbells insteading of the traditional doorbells have become the major trend of the times.Therefore,research has been conducted.And the development of a number of high-performance,multi-functional intelligent visual electronic doorbell is a thing with great social and economic value.Having been based on the analysis of the development status of visual electronic doorbell systems at home and abroadand aiming at the shortcomings of currently existing electronic doorbells,such as inaccurate parts detection,inaccurate human detection,low image quality,and inaccurate communication between the host and the guest,This article designs an intelligent visual electronic doorbell system with ARM.First of all,through the collection of data to determine the basic functions of the system,and then proceed from the functional requirements,determine the design,the system uses STM32F1 chip as the main control chip,and transplanted the UCOS-II operating system to make the system run more stable and smooth.In addition,there are five sub-modules: PIR,image acquisition,music prompt,storage,and communication.Moreover,this article has improved the human detection part of the doorbell system,and added a GSM module to the doorbell system so that the host and guest can communicate directly through the telephone.In this way,the human detection function of the doorbell system is more accurate,and the communication between the host and the guest is more timely.Finally,an interface was designed for the system?After debugging,the function of the system meets the design requirements.The system has fstable operation,beautiful interface,an simple operation and high promotion value.It provides a new idea for the development of intelligent doorbells..
