As seen from the above-described embodiment, family of the present invention cloud computing system, set-top box is inquiring home appliance when not having external computing capability, to the request of server output down load application calculation procedure, according to the application computer programs that server returns, export to the home appliance that does not have external computing capability; The data that the request of reception is calculated, the data that will ask to calculate according to the equipment with this computing capability of storage are divided into corresponding sub-calculated data, and distribute to corresponding equipment with this external computing capability; Receive the result of calculation that described equipment returns and merge the equipment that the request of exporting to is calculated.Like this, calculate by calculated data being dispensed in family's cloud computing system in all equipment with this calculated data computing capability, thereby make that each equipment can be shared computing capability in the system, effectively utilize in the system processor of device free and assisted calculating, promoted the utilance of home appliance processor, improve the computational efficiency and the resource utilization of family's cloud computing system, satisfied the amount of calculation of large-scale application such as graphics calculations, the decoding of audio frequency and video music.
Lift a specific embodiment below, the calculation process of family's cloud computing system shown in Figure 3 is described.
Fig. 5 is the calculation process schematic diagram of family of the present invention cloud computing system, and referring to Fig. 5, this flow process comprises:
In this step, application program comprises and this novel relevant application computer programs and other programs such as video reproduction program, browser program, Java Virtual Machine program etc.
In this step, after set-top box starts, by bluetooth, Wifi, GPRS (GPRS, General Packet Radio Service) wireless mode such as, or wired mode scans all home appliances (equipment) in (inquiry) access family cloud computing system, as mobile phone, computer, blue-ray DVD, intelligent refrigerator, intelligent air condition, television set etc., and find these equipment by interconnection agreement, interconnection agreement comprises plug and play puppy parc (upnp, Universal Plug and Play), IGRS, agreement such as e family is good.
In this step, set-top box can be passed through open service lock road standard (OSGi, Open Service GatewayInitiative) mode and inquire about the home appliance that connects and whether have the ability of external calculating, specifically can
Referring to the correlation technique document, do not repeat them here.
In this step, set-top box requires home appliance that device systems parameter (as type, model, the application computer programs downloaded) is provided, the type that provides according to this home appliance, model and the application computer programs downloaded are then downloaded the program (other application computer programs) of the calculation services client of this home appliance to outside service end.
In this step, set up the home appliance and the process that originally have external computing capability comprising of calculating passage with set-top box and download and install the home appliance that has external computing capability after the application computer programs.
In this step, when set-top box need be calculated, the initial data that needs large-scale calculations is cut apart, be about to import data and carry out subregion (such as being divided into the M piece), carry out to be distributed on the different home appliances with external computing capability.
In this step, set-top box is exported to the home appliance that each has external computing capability with divided data, and set-top box also can participate in calculating except the function of bearing master control, and the algorithm that sets in advance can upgrade as required.
In this step, suppose that set-top box needs large-scale calculations, then set-top box returns to amalgamation result the application of large-scale calculations.
So far, this flow process finishes.
In the practical application, set-top box also can interimly scan home appliance in the operation phase, if find the calculating pathway closure of certain home appliance, then reduces and cuts apart number; If find to have newly-increased home appliance and should have external computing capability by newly-increased home appliance, then increase and cut apart number, to this newly-increased home appliance output partition data.
If other home appliance also needs large-scale calculations, can send computation requests to set-top box equally; And, among the present invention, if the processor ability height (as mobile phone or computer) of home appliance, can be as set-top box, execution in step 408～step 411 is finished calculating by other home appliance, set-top box and server; If the processor ability of home appliance lower (as refrigerator), can cut apart the initial data of the need large-scale calculations of reception by set-top box, after the calculating by each equipment in family's cloud computing system, merge by the return results of set-top box again, and return to this lower home appliance of processor ability each household electrical appliances.
In the above-mentioned example, the postulated mechanism top box need calculate 1 to 1,000,000 add up, if there are ten equipment (not comprise set-top box, for example, nine home appliances and a station server) insert family's cloud computing system, then set-top box is (in the present embodiment, set-top box self does not participate in calculating) can be divided into 10 parts to the need data accumulated, every part 100,000 amount of calculation is (as 1-10 ten thousand, 100,000-200,000), every equipment (supposing that each home appliance is all identical with the external computing capability of server) calculates 1 part, and last every equipment returns to set-top box with result of calculation, set-top box adds up to result of calculation and obtains accumulation result, thereby finishes accumulation calculating.
More than lift preferred embodiment; the purpose, technical solutions and advantages of the present invention are further described; institute is understood that; the above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all; any modification of being done, be equal to replacement, improvement etc.; all should be included within protection scope of the present invention, the interest field that the present invention advocated should be as the criterion so that the patent application scope is described, but not only limits to the foregoing description.
