2 The feasibility of household appliances to access the Internet objectively has such a social need. From the home appliance manufacturers, with the further regulation of the market, the competition for the quality and price of home appliances to a certain extent requires competition in the quality of service. Putting forward the "zero" distance service and changing the mode of on-site service in the past, it is more convenient and quick for businesses and users to avoid unnecessary troubles. On the other hand, from the user's point of view, as information technology gradually penetrates into every aspect of people's lives, the consumer groups of a new generation of household appliances are beginning to take shape. They are not only interested in “surfing the Internet” or “online chat”, but also have novel performance. A new generation of home appliances with better service methods and better control methods will also be loved. Moreover, as an important part of smart home, it will bring consumers new feelings like never before.

(2) The relevant technical conditions have matured. The rapid development of computer, communication and network technology has led to the application of new control technologies for modern household appliances. The new low-cost embedded microcontrollers are widely used, replacing the mechanical control methods previously used in household appliances, effectively improving the operability and additional functions of home appliances.

For manufacturers, it can save inspection and maintenance manpower and make products more competitive; for users, the increased cost brings high-end service and convenience.

(4) With the reduction of communication tariffs, the consumption of Internet appliances can be accepted by most people.

3 The realization scheme of two kinds of household appliances on the Internet is TCP/IP protocol, and all the nodes connected to the Internet network must have a network interface supporting the protocol. Through it, people can access and use any resources on the Internet to view graphic information, send and receive emails, and transmit sounds and images in real time from anywhere on the current public network. However, it is different to realize the Internet access of household appliances. On the one hand, microcontrollers in home appliances are simple controllers, and their system resources and computing speeds simply cannot run complex TCP/IP network protocols. Second, the microcontrollers in home appliances are not uniform. There are various types of 4-bit machines, 8-bit machines or 16-bit machines, and the command systems are also different. If a set of interface programs is specially prepared for the Internet access of a certain home appliance, the cost is too high, and thus the practical possibility is not large.

At present, many domestic and foreign manufacturers have introduced many programs and countermeasures. It is necessary to let household appliances go online, but also to consider the ease of operation of consumers, but also take into account factors such as price and cost. Although products such as "online refrigerators" and "online TVs" have also been produced, they are difficult to stand at the price, operability and popularity. In particular, there is still a lack of corresponding standards in solving the problem of Internet access from different manufacturers and different brands of home appliances. This paper aims to give a low-cost to meet the needs of consumers in accordance with the development of China's communications and the actual consumption level of consumers, we have to provide Internet network interface and port address for each household appliance, independent Internet access and access is not realistic. The high cost and high cost incurred in this way are not conducive to the development of the Internet appliance itself. However, the information technology community system promoted by the development of broadband network technologies such as ADSL, HFC, FDDI, etc., especially for those who have relatively stable income and have higher cultural level in the fields of teaching, scientific research, administrative management, and commerce. The establishment of the information community environment, the development of Internet home appliances is quite potential. With the help of the cell information platform, in particular, the low cost of accessing the Internet to the user can completely connect the computer or home appliance 24h to the network. In this way, the problems that hinder the development of "online appliances" will be solved.

Shown is the home appliance Internet solution established by means of the community information platform. All household appliances in the home are attached to the standard serial bus and connected to the access controller through it. The access controller is connected to the microcomputer via a standard RS232 or USB interface and provides connectivity to home appliances with non-standard ports. The topology thus formed can be either bus-type or star-shaped. The characteristics of this scheme are as follows: (1) For the computer, the appliance is connected to the controller, which shields the difference between different household appliances.

(2) On the information community platform, the microcomputer in the home is a node on the high-speed backbone network of the community. It can exchange information with the household appliance production and sales service providers by means of the export of the community information platform. The cell network is connected to home appliance manufacturers and other such as BPCP, 110, 120, water and electric energy suppliers, etc. through BDN, ADSL, DDN and other public telecommunication networks. (4) In this component model, the microcomputer runs the TCP/IP protocol, which makes up for the technical and cost barriers caused by each household appliance being connected to the Internet. (5) Especially with the help of the cell information platform, the cost of sharing the Internet to the user is lower, and the computer and home appliance 24h can be hooked up to the network.

The household appliances through the community information platform Internet access scheme is for the non-information community environment, the independent Internet access scheme for household appliances. The home appliance access controller can be connected not only to the microcomputer, but also to the MODEM through the R-45 port, and then dialed to the central computer room of the home appliance manufacturer and other service providers through the public telephone network. There is a TCP/IP gateway. Then through the gateway to access the INTERNET. In this way, every consumer can control the electrical equipment in the home by phone or computer at any time and anywhere, and the after-sales service center of the manufacturer can also know the usage of the appliance at any time. In this mode, its characteristics are: (1) Each household appliance does not need to be connected to the Internet alone, but the TCP/IP gateway of the central computer room is used to realize the connection with the INTERNET. (2) The microcontroller in the home appliance receives and executes a remotely transmitted command via the Internet or sends some data out through the access controller and through the dial-up connection with the Gateway interface.

The main problem to be solved in the above two schemes is the interface problem of the appliance access controller and each electrical appliance.

The specification of the bus-type structure and related protocols need to be uniformly formulated to be implemented, and it is necessary to establish standards that are open and must be followed by major manufacturers.
