The main functions include: a) Monitor home devices in the system; b) Connect to the community public service network or the Internet through the IoT home intelligent terminal, to share network information resources and to enjoy network services; c) Realize the automation and intelligence of home devices, to provide a secure, efficient, comfortable and convenient home environment; d) Realize remote communication, monitoring, collection and management, to become an integral part of the smart community public service system; e) Select various transmission media, network topologies, communication protocols, access control methods for separate combination and design. 5.2 Overall structure The system of smart home for Internet of things is a multi-layered structure. Each device in the system can use different communication protocols. Its system structure is shown in Figure 1; it shall also meet the following requirements: a) The smart home net, device and its subsystems can be connected to the community through the IoT home intelligent terminal or its own network function, to form a community information management network, with the community integrated service platform; b) After the functional parameters and service information of the smart home devices for Internet of Things are transmitted to the home intelligent terminal via the network, they are stored in the database as device registration information. d) Security service function: it shall provide functions such as user management, access control, event alarm and intrusion prevention processing; e) Management service function: It shall provide functions such as fault diagnosis, system optimization, accounting management and online payment. 5.3.2 Extended functions The smart home for Internet of things shall include the following extended functions: a) Remote networking service: Access to the community local area network and the Internet, to share networking services; b) Automatic control: Perform automatic control of smart home devices for Internet of things c) Intelligent update of traditional household appliances: Traditional household appliances without network interface use infrared control, which cannot be directly operated by intelligent control. After using equipment compatible data converters, it can realize the intelligent control transformation of traditional household appliances. 6 System configuration and operation 6.1 Overview The system of smart home for Internet of things is mainly composed of IoT home intelligent terminals, smart home devices for Internet of things, and communication networks. The IoT home intelligent terminal is the core of the entire system of smart home for Internet of things. External devices are connected to the IoT home intelligent terminal through the public communication network, so as to realize the control operation of the smart home devices for Internet of things. Within the scope of home, the IoT home intelligent terminal is also the main controller of the system; it controls and operates various smart home devices for Internet of things through standard communication interfaces. 6.2 Key devices 6.2.1 IoT home intelligent terminal 6.2.1.1 Basic requirements 6) Perform identity authentication, password protection and other security identification. c) It shall have the functions of Web server and database, and the following functions: 1) Monitor on the two ports of the external network and the internal network; respond to remote and local requests for access at any time; 2) Use TCP/IP protocol and HTTP-based protocol to process requests and transmit device status information, including transmission to remote (Ethernet port) and local (home network port); 3) When the device status information changes, it can actively send real- time status information to the connected IoT home intelligent terminal. 6.2.1.2 Hardware design requirements The hardware of the IoT home intelligent terminal shall meet the following design requirements: a) It shall support the operation of embedded operating system; b) It shall have a remote (Ethernet) port and a local (home network) port; reserve a spare port; c) It shall have a browser operation mode, and realize centralized control of the entire household equipment through the local operation interface; d) It shall have the display function or voice function; e) It shall be able support wired or wireless way to form a smart home net, and be compatible with various fieldbus, Ethernet, ZigBee protocols and other radio frequency networks; f) It shall be able to upgrade the system, and has expansibility, to add smart home devices for Internet of things at any time without additional expenses. 6.2.1.3 Software design requirements The software design requirements shall include the following functions: a) Initialization and self-check functions, including CPU chip, smart home net communication, Ethernet communication and other module initialization functions; a) It shall have a communication interface of smart home net communication protocol, that is, it shall have the smart home net communication protocol function; b) It shall have the device description file of all its own functions and services, which shall meet the requirements of GB/T 35134; c) The informatization and intellectualized reconstruction of traditional home devices is to embed the communication interface of the smart home net communication protocol, and to generate the "function table" (or "operation table") of the home device into “device description file” according to the format requirements of GB/T 35134. 6.2.4 Device compatible data converter The device compatible data converter is a smart home device for Internet of things. Traditional household appliances without a smart home net communication interface are controlled by infrared, which cannot be directly operated by intelligent control. The device compatible data converter obtains device information by inter-converting the infrared signal and the RF signal and connecting to the control terminal, to realize the intelligent control of traditional household appliances. It is the device middleware of the smart home net and shall meet the following basic technical requirements: a) The device compatible data converter can be a wireless/infrared converter. As a sub-device of the control terminal of smart home for Internet of things, it shall clarify its control object in the system application; b) After the system is started, the control terminal of the smart home for Internet of things identifies the compatible data converter-controlled object, and uses the communication protocol to transmit the device description file to the control terminal of the smart home for Internet of things. The control terminal of the smart home for Internet of things analyzes the device description text and assigns addresses to the controlled object (sub-device), to complete the self-organized network of the device; c) After the device compatible data converter receives the radio frequency control signal that is sent by the home intelligent terminal or control terminal of the Internet of Things, it converts it into an infrared signal, to complete the intelligent control operation of the infrared household appliance. 6.3 System composition 6.3.1 Basic subsystem 6.3.1.1 Smart home appliance system Provide background music, short films of music, players and other audio-visual environments that make the home living environment comfortable, and have convenient and quick control operations.......
