Design And Implementation Of Remote Monitoring System Based On QQ IoT

With the rapid development of Internet of Things technology,embedded technology,and computer network technology,a wide variety of monitoring systems have emerged,and they have played an irreplaceable role in security protection,scientific experiments,smart homes,and medical and health care.Currently,the monitoring environment faced by the surveillance system is becoming more and more complex,and the monitoring requirements are getting higher and higher.Problems such as the need for additional third-party APP portals,single cloud service functions,and the lack of linkage between users and devices are becoming increasingly prominent.In the new era,how to effectively integrate the Internet of Things technology and monitoring system,how to use the Internet of Things platform to make the monitoring system more intelligent,more humane,and to bring better monitoring experience to users and other question become a hot spots in the monitoring area.Under this background,this article designs and implements a set of remote monitoring system based on QQ platform,combining the embedded technology,Internet of things technology,network technology and video and audio processing technology.The system is divided into three aspects:monitoring terminal,server and client.First of all,monitor the terminal hardware with JZ2440 development board as the main body,use ARM920T core S3C2440 microprocessor as the processing core,external OV7740 CMOS camera,WM8976 sound card chip and network card chip.In the system software ported the embedded Linux operating system,completed the development of related hardware drivers.On this basis,according to the QQ IOT SDK,the use of multi-threaded technology to complete the development of the application program,to achieve audio and video acquisition,encoding and data transmission capabilities.Secondly,we chose to use the QQ IoT platform as a server.By configuring the server background,we achieved device authentication for the access platform and data exchange hetween the two Finally through the QQ IoT platform,the system control page embedded in the mobile QQ is designed to complete the development of the client,and the QQ message channel capability is used to turn the monitoring terminal into a "QQ friend".You can access the monitoring terminal through the mobile QQ anytime,anywhere.Receive and view video and audio data.Monitoring data can also be shared through the QQ account system and relationship chain,which increases the linkage between users and devices.Through the testing and analysis of the entire system and various functional modules,the use of mobile QQ can access the monitoring terminal and achieve video surveillance and voice message functions.Finally,based on the test results,the system proposes some improvements.
