Communication Technology Of The Information Refrigerator

On 28th, June 2005, information department releases "the plata of the home net" ,that means the formal approvement of the two independent property right standards which are E home and IGRS.Now IGRS's products are most applicated in IT and IT's peripheral equipments such as PC,printer,projector and PDA,also include TV multimedia decode and communication,but most application in office environment.E home only include home connection and communication,including white household electrical equipment ,black househuld electrical equipment and small household electrical equipment.As a kind of information household electrical equipment, information refrigerator are composed as food management, menu management,help system, long-distance Internet and error alarm, feed back refrigerator run condition,wirelesss communication and control fuction,and so on. Information refrigerator has been declared detailed system structure and commucation standard in E home,but not a little in IGRS. This thesis -information refrigerator communication discusses information refrigerator communication how to adapt to E home and IGRS two kind of home net standards together.This thesis mostly researches in the following directions,Research E home and IGRS two kinds of home net standard, and issue information refrigerator adpative system structure.Research E home and IGRS two kinds of home net standard, and confirm information the communication protocol of the information refrigerator.Research E home and IGRS two kinds of home net standard, and analyse lineate, wireless and such as physical connection method.According to technology, home control subsystem net project is issued by connection and mutual auto control of the home illumination, safety, electrical equipment and foundation establishment, which are belonged to household automatization and intelligent home appliances. And household trunk net is defined by soluting the mutual connect and communication , plug and play of the advanced household information equipments, such as computer, household gateway, printer, DMA and so on. In the viewof the practicality, home control subsystem net's each device has a low cost and comparative simple function.For example a illuminate device or a microwave oven can cooperate with simple communication protocal of twisted-pair , infrared,electrical wire and such as medium.However, household trunk net's devices are more severed to PC kinds devices.And than they cost more than the illumination device,and production property is more complex. So it is rational to use an advanced mutual connection and communication protocal.In fact,IGRS is the development of the household trunk net,and E home is the development of the household control subsystem net.Two of them are not absolute conflict.According to intenational technology standard,such as UpnP , OSGi, DHWG,these kinds of famous international standards are identity with IGRS. And CEBuS, X10, LonWorks, ECHONet, EIB are solve the same problem with E home.So,these two kinds of household nets,IGRS and E home,are emphasized the different object,but with the development of the technology,they can unite together. At the same time,for many manufactures have a large different function requirement in the information refrigerator,for example some manufactures made a 15"LCD in refrigerator,which can play music and vidio, surf the net,control function as a mobile,or automatic buy function.But in home net system,information refrigerator as a household electrical equipment should have a limited function, other function should be fullfilled by home gateway or computer. So, this thesis issued a home net model,which detailed analyzes each faction of them.
