Design And Application Of "Internet Plus" Intelligent Cloud Visual-speaking System

In view of the security and convenience of the cell cluster,many cells have been built with access control talkback system,but the traditional access control intercom system is based on analog technology or digital technology design,the system wiring is complex,the equipment is more and more difficult.With the passage of time,the system and equipment are gradually aging,and the construction and management cost is very high.Talk about access control.The main contents of this thesis are as follows:An intelligent cloud system is constructed by using Internet and cloud platform,which comprises a cloud talkback service platform,a smart cloud user APP and a smart door access terminal,etc.The whole system is connected to the cloud server through a wired broadband network or a 4G wireless broadband network through a wired broadband network or a 4G wireless broadband network,and the intelligent access terminal installed at the door of the cell or the door of the unit building is connected to the cloud server through a wired broadband network or a 4G wireless broadband network.The streaming media transmission system based on SIP communication module and 3GPP is designed,and the streaming media codec and transmission between mobile phone app,access control terminal and background server are realized.An app based on IOS and Android is developed to realize remote control of intercom access control,audio and video call and message push and receive,and to undertake intelligent community service.4.The hardware circuit and software module of intelligent access intercom terminal based on T40 S and STM32F072 master-slave dual-processor are developed to realize the platform interactive connection,remote management and audio and video coding and compression transmission.At present,the system is widely used in Guangzhou,Shenzhen,Foshan,Shanghai and so on.
