Description
Technical field
The present invention relates to a kind of joining method of the distributed data based on URI.
Background technology
Along with the fast development of electrical network economy society of China, power consumption increases rapidly, and the scale of electric power system constantly expands, and the connection between electrical network is also increasingly sophisticated.For application such as picture relay protection setting calculation, in order to ensure the accuracy calculated, the electric network data of the thread be associated must be considered to bring within computer capacity.Like this, the problem how data that just must relate to different threads can be stitched together accurately.
Summary of the invention
Object of the present invention is exactly that provide a kind of joining method of the distributed data based on URI, it has the data that can realize whole electrical network accurately can splice advantage automatically in order to solve the problem.
To achieve these goals, the present invention adopts following technical scheme:
Based on a joining method for the distributed data of URI, be mainly divided into following steps:
Step (1): the construction scope determining distributed system: according to the construction scope of distributed system, determines the thread needing to distribute prefix, generally, can be designed to a thread and distribute a prefix;
Step (2): the URI prefix of configuration schedules unit data: in order to ensure that the URI of each object is unique at the whole network, configuration must ensure uniqueness to the URI prefix of each thread, specific practice be according to thread between administration relation, encode one by one, the thread prefix that level is higher is shorter, and the coding between level adopts period to separate;
Step (3): based on URI prefix code object: the modeling of distributed data meets CIM-61970 standard completely, when producing data object, the URI of data object is that the upper data object ID of URI prefix splicing of this thread is formed;
Step (4): object-based URI splices data: in the modeling process of distributed data, the association between data object is recorded by the URI of data object, the URI of data object never revises after generation again.Thus ensure that the association of recording in each data object is still effective, which achieves the seamless spliced of data object when the application data environment of data from the application data environmental renewal of source thread to object thread.
Technical term is introduced:
URI: Uniform Resource Identifier, be the unique identifier for each data object distributes, this identifier is unique within the scope of full electric network.
In distributed data maintenance system, the base unit of data is objects.Data in order to ensure each thread can be seamless spliced, must guarantee that the numbering of each object is unique, and this unique numbering also needs certain symbolical meanings in addition.The threads at different levels of electric power system are a tree-shaped tissue in general, use for reference the domain name method for organizing of the Internet, for each object gives a URI, as long as like this for each thread in electrical network determines different URI coding prefixes respectively, so just can ensure if an object is unique in thread inside, also be so unique in its data in whole electrical network, these data that just can realize whole electrical network can accurately be spliced automatically.
Beneficial effect of the present invention: actual in conjunction with electric power system application, under this method solves distributed data maintenance environment well, the seamless spliced problem of the data of each thread.Long-range from power network development, the complexity that electrical network connects constantly is strengthening, and the way that the way of dependence equivalence in the past reduces computer capacity more and more seems infeasible, unreliable.And this method solves just on a large scale electrical network calculate must problems faced, that is: data are safeguarded respectively by multiple thread, but the scope calculated spans multiple thread really.Thus the appearance of this method, the electrical network for a change calculates and is limited to data maintenance scope, and for contacting the calculating of day by day close bulk power grid, paved road, established important foundation, the safe and stable operation for electric power system is significant.

Fig. 1 is method flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, a kind of joining method of the distributed data based on URI, is mainly divided into following steps:
Step (1): the scope determining distributed system: according to the construction scope of distributed system, determines the thread needing to distribute prefix.Generally, a thread can be designed to and distribute a prefix;
Step (2): the URI prefix of configuration schedules unit data: in order to ensure that the URI of each object is unique at the whole network, configures and must ensure uniqueness to the URI prefix of each thread.Specific practice be according to thread between administration relation, encode one by one, the thread prefix that level is higher is shorter, and coding between level adopts period to separate;
Step (3): based on URI prefix code object: the modeling of distributed data meets CIM-61970 standard completely, when producing data object, the URI of data object is that the upper data object ID of URI prefix splicing of this thread is formed;
Step (4): object-based URI splices data: in the modeling process of distributed data, the association between data object is recorded by the URI of data object, the URI of data object never revises after generation again.Thus ensure that the association of recording in each data object is still effective, which achieves the seamless spliced of data object when the application data environment of data from the application data environmental renewal of source thread to object thread.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
