Intelligent home network architecture, including within the family network system, intelligent home controller and the intelligent home network and external Internet networks of data communications. Among them, the smart

In addition, smart home controller should also be equipped with automatic alarm and other functions, that is, when found, such as alarm signal: it was a malicious intrusion, high temperature, etc., the controller can be

22、 the smart home system to solve the bottleneck before the key technology. GPRS (General Packet Radio Service) is short, the existing GSM system is to add a new GGSN (Gateway Support Node) and SGSN (Service Support Node) node developed a new packet data bearer services. GPRS with the existing GSM sys

Originally, smart consume

25、r appliances are just stand-alone devices that have the control program running by themselves. Due to hardware limitations, these appliances can only implement some simple control algorithms that can at most achieve local optimal control effects. Nowadays more and more consumer appliances have the c

26、apabilities to benter connected by many kinds of communication media such as phone lines, utility lines, and wireless technology, and even can be connected to the Internet. This trend of development brings promising prospects to future home appliances that will not only let users maintain, monitor,

27、and control appliances more easily and conveniently, but also will make the long-time expected remote-controlled home appliances feasible. A remote-controllable home appliance can be considered as a slave device to the remote controller that resides in far end and has powerful mainframe running adva

28、nced control algorithms. The appliance runs its own control program while at the same time can receive control commands, configuration parameters or even updated control algorithms from there mote controller to achieve optimal control effect in the global level. In order to meet this challenge, a ne

29、w architecture for smart consumer appliances systems needs to be proposed.On the other hand, Hardware implementation of control systems will be one of important issues in the development of smart consumer electronics. For simple applications, such as smart toys, microwaves, and washing machines, sim

30、ple control algorithms can be used and implemented on a single chip that may cost very little. However, for more complex problems, such as smart heating, ventilation, and air conditioning (WAC) for individual houses or office buildings, advanced control methods must be utilized and implemented with

31、sophisticated hardware that would cost significantly more than the conventional controllers. For example, an intelligent PLC (programmable logic controller) for energy efficient and waving temperature control may cost several times more than a household air conditioning unit. This might be justified

32、 for some industrial applications but obviously not acceptable for average individual customers. Therefore, to make smart consumer electronics marketable for this type of applications, innovative approach for implementation must be established to reduce the cost to a level acceptable to average cust

In the following sections, the architecture of intelligent control systems for consumer appliances via Internet is briefly presented, and then a network-based memos-fuzzy implementation is described.2.Architecture of Networked AppliancesFigure shows two versions of architecture for networked appliances.
