In order to realize the network function of household appliances, each household appliance should have a communication module. Different physical media need different communication modules, and the communication module is the interface for upgrading traditional home appliances to network home appliances. In order to ensure the correct communication between household appliances and between household appliance networks and gateways, a complete set of communication protocols must be formulated.

(3) Application of embedded system

Traditional household appliances are mostly controlled by single chip microcomputer. After the traditional household appliances are upgraded to network appliances, in order to realize the seamless connection between network technology and household appliance control system, the embedded software with network function and the control software program of single chip microcomputer are adjusted accordingly to organically combine them into a complete embedded system.

3.2.4 Home Automation

Home automation refers to the use of microprocessor electronic technology to integrate or control home electronic products or systems (such as lighting, air conditioning, water heaters, computer equipment, security systems, video and audio systems, etc.). ). Home-based systems mainly use the central microprocessor (CPU) to receive information from related electronic and electrical products, and then use established programs to send appropriate information to other electronic and electrical products. The central microprocessor must control household appliances through many interfaces, which can be keyboards, touch screens, buttons, computers, telephones, remote controllers and so on. Consumers can send signals to or receive signals from the central microprocessor.

With the wide application of network technology and the gradual maturity of network appliances, many functions of home automation will be integrated into these new products. It can be seen that home automation is the research direction of smart home.

Combined with the current development of information technology and human requirements for home environment, it can be predicted that the future smart home will have the following functions: sending and receiving information; Manage the financial situation of individuals or families; Manage the communication needs of the family; Manage the use of power supply and equipment; Provide a safe and reliable environment; Maintenance-free operation; Simple operation; Can be customized according to personal or family lifestyle. Network home appliance is a new type of home appliance designed by using digital technology, network technology and intelligent control technology. Internet users can be interconnected into a home internal network, which can be connected with the external Internet, thus forming a network home appliance system.
