Embodiment
Fig. 1 shows the concrete structure of intelligent home network disclosed by the invention, mainly comprise the digital home intelligent gateway of household internal, bus switch, industry ethernet, 485 buses and various smart machine, gateway and controlled plant are coupled together by 485 buses.
Fig. 2 shows the device address structure in intelligent domestic system disclosed in this invention.Device address is divided into fixed address and dynamic id address, and fixed address is solidificated in storage chip before equipment dispatches from the factory, and dynamically id address is then that after equipment first time access bus, gateway gives to distribute the address as this node communication.
Namely equipment fixed address is the unique identity card number of each equipment, and it can be made up of one of them of the sequence number of the batch code of the bar code of device type, equipment, equipment and equipment or several combining.This addressing method can ensure the uniqueness of each equipment under different scenes.
Fig. 3 A illustrates the first embodiment, if controlled plant only has unique one in intelligent home network, and such as guard for entrance gate.So equipment fixed address can only include the bar code of device type code and equipment.
Fig. 3 B illustrates the second embodiment, if controlled plant comprises multiple, such as, but uniquely can determine according to the bar code of controlled plant and a batch code, the equipment of the same type progressively added, so equipment fixed address can only include device type code, the bar code of equipment and equipment batch code.
Fig. 3 C illustrates the 3rd embodiment, if controlled plant can not by batch and bar code uniquely determine, such as lighting apparatus.So equipment fixed address can comprise device type code, the bar code of equipment and equipment batch code, equipment serial number.
Be not limited to above-mentioned three embodiments, according to the difference of application scenarios, as long as the uniqueness of fixed address can be ensured, so just can one or several in the sequence number of combination in any device type, the bar code of equipment, the batch code of equipment and equipment to form fixed address.
When the 3rd embodiment, equipment fixed address is made up of 17 bytes, and wherein first character joint is device type, and then 12 bytes are the bar codes of equipment, then add the lot number of 2 byte representation equipment, the sequence number of latter two byte representation equipment.Certainly can be the byte number that different field distribution is different according to specific needs.In first two embodiment, the byte representing respective classes can be removed, thus form shorter equipment fixed address.
And the dynamic I D address of equipment is determined by home gateway, its length can be determined by practical application scene, the total quantity of such as equipment.In one embodiment, dynamic id address is made up of 2 bytes, from 0x00 to 0xffff, so altogether can represent 65536 dynamic id addresses of equipment, because dynamic id address only has two bytes, very brief, also enough at same Smart Home on-net location, so can call duration time be reduced with this address as the mailing address of equipment each in bus, reduce the probability of data collision, substantially increase communication efficiency.Certainly, also can adopt other length, such as more than 1 or 3 byte length represents dynamic I D.
The function including multicast in IP address protocol, to realize the information transmission to one group of equipment, includes the function that group controls equally in the address distribution method that the present invention is corresponding.For Lighting control, in wired home, often need to control different place in family, the light of difference in functionality.In general, a controller controls one or one group of light, and multiple controller controls one or one group of light, that is to say one to one, one-to-many, many-one, the relation of multi-to-multi.And the dynamic I D address of the form of group address and equipment is similar, its length can be determined by practical application scene, such as the total quantity of equipment group.In one embodiment, organize dynamic id address and be made up of 2 bytes, from 0x00 to 0xffff, so altogether can represent 65536 dynamic id addresses of equipment group.Certainly, also can adopt other length, such as more than 1 or 3 byte length represents group dynamic I D.
Fig. 4 shows smart machine and adds group process.First each controlled plant needing to add a group is determined at gateway; The dynamic id address of this group of gateway generating identification; Gateway sends group address assignment message to each controlled plant in this group, and this message comprises the dynamic id address of group; Each controlled plant in group receives this message and stores group dynamic I D address wherein.Because equipment can belong to several different groups simultaneously, therefore controlled plant can store the dynamic id address of multiple groups.
It should be noted that first equipment self must obtain unique equipment dynamic I D address, then can add a group.Therefore, determine the step needing to add each controlled plant that is organized at gateway before, controlled plant must send fixed address notice message to gateway, and wherein this notice message comprises the fixed address of equipment; Then, gateway carries out necessary verification after receiving this notice message, and then distribute a unique dynamic I D address according to Operation system setting to equipment, this dynamic I D address by system Random assignment, also can be specified by user; Then, gateway sends dynamic ID distribution message to equipment; Then will wherein store by dynamic I D after equipment receives dynamic ID distribution message, and in communication afterwards all with this dynamic id address as mailing address.Then the controlled plant obtaining dynamic I D address can be added group by gateway.
Fig. 5 shows the process that smart machine exits group.First gateway determines controlled plant in the group that needs are deleted; Gateway sends group address to the equipment needing to delete and deletes message; The equipment that these needs are deleted just is deleted the corresponding dynamic id address of group after receiving the message exiting group, so just exits this group.
Be understandable that, the application's claim is not limited to these specific open forms, but covers all alter mode, equivalents and the substitute mode that fall within the spirit and scope of the present invention.
