Embodiment

In Fig. 1 system entire process process flow diagram, client is sent request to service end, wishes to browse certain file (S1) on the service end;

Equipment is consulted, and seeks relevant device in the slave unit tree, information such as the manufacturer of service end query user's end, model, so that in device tree, locate this equipment (S2), and if do not find this equipment, then failure (S7); Capabilities match (determining the display capabilities of equipment), the node according to (S2) determines in device tree finds the ability description (S3) corresponding to this node in the ability tree; Data generate, and the result according to the capabilities match of (S3) is described generates pending data, just can be correspondingly processed, and the data (S4) that generating client needs are returned net result (S5) to client, successfully finish (S6), and end (S7) makes mistakes.

Fig. 2 equipment is handled through consultation in the process flow diagram, and after client was sent browse request, equipment was consulted to be meant that mobile device sends browse request to service end, after the service end response, sends the process of consulting instruction to client.This is a question answering process, and purpose is to allow service end understand the ability of browsing of client.Service end is inquired manufacturer (S8) to client, and service end is searched producer (S9) in device tree, and service end is inquired its product type (S10).Service end is looked into this model in device tree, in device tree, mate corresponding entry (S11) then, if find, even if equipment consults to complete successfully (S12) so, otherwise equipment is consulted failure (S13), and service end can be returned corresponding error message (as shown in Figure 2) to client.The device tree here be meant according to the production firm of equipment with and products thereof the tree structure (as shown in Figure 3) formed.Manufacturer is a father node one by one, and the product of manufacturers produce so just can be organized into one tree shape structure as the child node under it, and it has described the manageable equipment of native system, and every equipment that occurs on this structure can be handled; Otherwise, all can not handle.

Fig. 3 device tree has been expressed each manufacturer and products thereof, Fig. 4 capabilities match processing flow chart, Fig. 5 ability tree, and node and device tree are corresponding one by one.Expressed among the processing power figure of corresponding device, capabilities match is meant the process of service end according to result's unique definite capacity of equipment in the ability tree of back equipment negotiation.Each node of ability tree (as shown in Figure 5) has been described the processing power of equipment, such as the ability that certain node is represented is: monochromatic English.Just expression and this node corresponding equipment can show black and white picture and can not the display color picture for these; Can show English and can not Chinese display.In general, the node of ability tree and the node of device tree (as shown in Figure 3) are one to one.Like this, after the node in unique definite device tree (equipment negotiation),, just can find the node (S15) of corresponding ability tree very easily, just can complete successfully capabilities match (S16) by the corresponding node (S14) of compare facilities tree and ability tree.This scheme is very easily for the expansion of equipment, and we only need add the equipment that needs support in device tree and ability tree, and the capabilities match process just can be carried out automatically, thereby supports new equipment easily.In the ability tree " default ability " node is arranged.Meaning of it if certain novel device does not have corresponding node in the ability tree, will forward " default ability " this node (S17) to so when carrying out capabilities match.Model B product as the B of manufacturer among the figure does not have corresponding node in the ability tree, so system default has matched " default ability " node." default ability " node is generally only supported the limited ability of browsing, such as monochromatic, English character collection.

Fig. 6 data generate among the figure, and the data generation is meant the result of service end according to capabilities match selects suitable filter, generates the process of final data.The filter here is meant a kind of like this processing procedure: for identical input data, after different filter processing, can produce different output (as shown in Figure 6).The expansion of system is also very convenient, and what specifically need do is exactly to design each filter, makes to reach desirable effect, this filter is added in the filter set to get final product then, and this has just well solved the maintenance and the upgrading of system.。

As shown in Figure 6, be the example that data generate.Such as certain webpage of a Web website, this webpage is to have the picture of one 256 look and " the 256 looks English webpage " of the English explanation of a part.If service end is selected to load one " 16 look filter " and one " Chinese filter ", be used for respectively 256 chromatic graph sheets are converted to 16 chromatic graph sheets and convert english information to Chinese.After handling like this, the final data of output has just become " Chinese web pages of 16 looks ".And whole process is transparent to the user.

Good effect

The whole frame structure of system has fully taken into account autgmentability and maintainability, and substantially need not Change already present webpage, only need between client and service end, add last layer and just can well separate The series of problems such as the compatibility of determining are effectively protected business investment; While is for the support of later new product Also just design some filter, and to the maintenance of device tree and ability tree, very simple. System architecture is not needed to do any adjustment, and this is just so that the support of businessman can be very timely. A series of Superior part so that this programme have a good application prospect.
