Accompanying drawing explanation
Fig. 1 is the structured flowchart of management system of the present invention.
Embodiment
Below in conjunction with accompanying drawing, a kind of method administrating system based on text resolution management video camera that the present invention proposes is described in detail.
Management method of the present invention utilizes a type configure file video camera model to be carried out to the technology supported flexibly, and type configure file uses XML format.XML is one descriptive language flexibly, but for concrete use field, needs to define various XML tag, the structure of design XML.Management method of the present invention is exactly to define XML tag and structure for every characteristic of video camera, according to the restrictive condition etc. between camera properties design data span, characteristic support, mark, thus make to use a set of program code just can support numerous video camera models.Can not revise on the basis of code simultaneously, model is in the future being supported.
Management method of the present invention is specific as follows:
1. about compatible model process:
Because although some video camera model model name is different, but for video camera place system configuration tool characteristic be identical, we call compatible model this model, for preventing re-defining, a type configure file is only had for compatible model, is described in devices.xml.
Under operation catalogue, under devices.xml and type configure file are put in Model catalogue.
In code, selected by each basis, model first checks compatible model list, then the corresponding type configure file of corresponding inquiry is removed, according to type configure file determination camera properties, to show different spans, different fields, different restrictive conditions on interface.
The design of compatibility list and content (devices.xml) example:
Code 1:
Wherein IPC6122-P and IPC6122-D just belongs to compatible model, according to XML, code can judge which model belongs to compatible model, uses same type configure file to process." config=" IPC6122-P " " specify the title of type configure file.
2. configuration file content design
Configuration file design should be convenient to understand, and facilitates routine processes again simultaneously, also will ensure certain versatility and dirigibility.
In configuration file, each node represents a kind of characteristic of video camera, has relation of inclusion between characteristic, also has the mutual restriction relation of span.
The design of 2.1 support characteristics
Whether support uses nodal community " support=" true " ", the node of all configuration files is the characteristic that known video camera is supported the most entirely, if do not supported, nodal community is false.
Such as: in code 2, <ConfigWizard support=" true "/> just represents that this model supports configuration wizard function.
The design of 2.2 value condition allowed
The value allowed in the numerical value of the attribute configuration of video camera comprises can only choose a value among several value, comprises in addition and can input arbitrarily a value within the scope of certain.Now we devise Item node and Min, Max node.
In following code 2, mark the scope that 1 part just represents a kind of selectable value: it illustrates user and can only select in " default setting (Default settings) ", " high-definition quality (High quality) ", " bandwidth level and smooth (Balanced) ";
Mark in code 2 in the AlarmCheckInterval node of 2 and then provide Min, Max, it represents that user can fill in any value when arranging alarm detection interval properties between 1 to 256.
Restriction and the design restricted mutually between 2.3 attributes
Mutex relation: in order to express certain field certain value select after, another one field just can not select certain value, then represent with Mutex, be exactly represent that the mutex relation with certain node, constrained nodes location expression path use absolute path to express more clearly and which node-disjoint in XML expresses
Mutual exclusion Mutex node as marked 3 in following code 2 represents the resolution mutual exclusion of 1080P in that Stream of main bit stream+subcode stream 1+ subcode stream 2 and other id=0.And the physical meaning of this expression, have selected " main bit stream+subcode stream 1+ subcode stream 2 " if having expressed, main bit stream (code stream of id=0) just can not select this option of 1080P.
Scope limits: in order to express after certain field have selected, can cause the restriction of other field span, using Limit to represent.
Mark in following code 24 with the node of Limit represent elected selected mjpeg after, the limits value of Frame node (afterwards Frame purple node) can only select 1-5.And its physical meaning represents when user have selected mjpeg, then frame per second can only select 1-5.
Code 2:
3. the routine processes of configuration file:
The skills such as judgement, quantity circulate flexibly can be used in program design to carry out sweetly disposition according to the content of XML.Main process is all arranged in " the interface loading " and " operation judges " of Fig. 1.
As shown in Figure 1, the management system that management method of the present invention adopts comprises interface, interface operation process, task process, physical layer interface, model processing module, common process module etc.Wherein model processing module is responsible for processing the otherness of model, contains above-described three functives.Fig. 1 illustrates the relation between modules.
Table 1 describes the function responsibility of each submodule in model processing module.
The function responsibility of each submodule in table 1 model processing module
Whole management system, because each configuration file uses XML format, therefore has the submodule of special disposal XML format in public module.
In model processing module, the relation of each submodule as shown in Figure 1, and interface loading submodule and operation judges submodule call model attribute reading submodule and read, and model attribute reading submodule call XML process public module helps processing XML form.
Each configuration file uses XML format, and file representative video camera model, which describes the function detail of this model video camera.Configuration file uses the name of video camera model name, as IPC6112-P.xml represents the type configure file of IPC6112-P.
3.1XML process
The XML initialization of XML module reduction, release process, facilitate the read-write of XML node, attribute.The Component Gallery of inner utilization MSXML.
3.2 model attribute read-writes
Model attribute module for reading and writing carries out specialized business processing further for XML operation, encapsulates, carries out transparence access to video camera attribute, shield the reading process of XML to bottom.This module interface comprises: read default value, read video camera protocol type, read camera properties support situation, read span, reading attributes data list etc.
3.3 operation judges
Operation judges module is dispersed within interface logic process, needs the different qualities obtaining video camera to operate according to concrete service logic.
3.4 interfaces load
Interface load-on module is dispersed within the loading processing logic of interface, and the different qualities obtaining video camera according to different interfaces carries out interface display.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., it all should be encompassed in the middle of right of the present invention.
