Abstract
The present invention relates to an optimized SCD file editing method. The method comprises: reading an SCD file in a disc, acquiring n mutually independent sub-SCD files through a decoupling mode, editing the sub-SCD files one by one, and then obtaining a new integral SCD file through a combination mode. IEDs in SCD files are relatively independent and greatly influence the sizes of the SCD files, and grouping is performed according to the IEDs to form SCD files which are easy to realize; moreover, when the sub-SCD files with relatively small volumes are operated, less memory is occupied, so that by using the method, editing operation of the SCD files of multiple IEDs can be realized.
Description
Technical field
The present invention relates to intelligent substation field, the SCD file edit methods of particularly a kind of optimization.
Background technology
Along with speeding up the construction of intelligent station, the extension of intelligent station scale, the raising of intelligence degree, the equipment such as switch, merge cells, intelligent terminal all add the model of oneself, and are all increased in SCD file by model.In SCD file, device number reaches after some or size reach some, and committed memory is very many.
With present 32-bit operating system, Installed System Memory maximum address scope is 4G, and the internal memory of configuration 4G, usually available internal memory is less than 3.2G.Operating system takies about about 1G, therefore to application program use memory headroom only slightly larger than 2G.
For the SCD file more than 200M, or more than the SCD file of 500 IED, due to needs its node added, delete, edit, the operation such as insertion, so need all to be loaded into internal memory, usually with DOM mode resolution file, committed memory is very large, usually more than 2G internal memory is needed, therefore, after being loaded into file, calculator memory is in critical conditions, operating speed is seriously slack-off, once in a while, internal memory application failure can be caused, and cause work to preserve.
SCD file is formed by SCL language editor, it is the full station CONFIG.SYS in intelligent substation, usually by Header, Substation, Communication, IED, DateTypeTemplates totally 5 parts form, except IED part constantly increases along with the increase being loaded into IED quantity, Main Function is accounted on internal memory impact.
Existing SCD file editing process as shown in Figure 1, is that whole object processes with SCD, first SCD file is loaded into internal memory, then edits it in internal memory, adds, inserts and the operation such as deletion.Therefore for the SCD file of many IED, committed memory is more, and easily causes system processing speed slack-off, the problems such as program crashing.
Summary of the invention
The object of this invention is to provide a kind of SCD file edit methods of optimization, in order to solve the large problem of existing edit mode committed memory.
For achieving the above object, the solution of the present invention comprises:
A SCD file edit methods for optimization, it is characterized in that, step is as follows:
A) by SCD file decoupling zero be some sub-SCD file;
B) respectively editing operation is carried out to each sub-SCD file, and be saved in the sub-SCD file of each correspondence;
C) each sub-SCD file merging is saved as SCD file to disk.
Further, open SCD file in disk and adopt SAX mode.
Further, sub-SCD file internal memory employing DOM mode editor preservation for another example.
Further, divide into groups according to IED quantity during decoupling zero SCD file.
This patent proposes the optimization method of a kind of SCD file editor, in disk, read SCD file, obtains the individual separate sub-SCD file of n, one by one after antithetical phrase SCD file editor, then obtain new complete S CD file by the mode merged by the mode of decoupling zero.In SCD file, IED is relatively independent, and the file size impact of IED on SCD is comparatively large, divide into groups according to IED and form sub-SCD file to be easy to realize, and when the sub-SCD file of small volume is operated, internal memory occupies less, can be realized the editing operation of the SCD file of many IED by the method.
Accompanying drawing explanation
Fig. 1 is existing edit mode process flow diagram;
Fig. 2 is the edit mode process flow diagram of embodiment.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
A SCD file editor's optimization method, reads SCD file in disk, obtains the individual separate sub-SCD file of n, one by one after antithetical phrase SCD file editor, then obtain new complete S CD file by the mode merged by the mode of decoupling zero.
Its detailed step is as follows:
A) SCD file is read from disk, as adopted SAX mode;
B) to SCD file, with IED quantity, decoupling zero is multiple sub-SCD file; Antithetical phrase SCD file is loaded into after internal memory carries out editing operation from disk employing DOM mode and is saved in sub-SCD file;
C) sub-SCD file merging saves as SCD file to disk.
Usually, the sub-SCD after each decoupling zero has its relative independentability, and what can complete itself opens editor, preserves release.As long as therefore asynchronously edit all sub-SCD file, just have a large amount of internal memories idle.
Concrete, as shown in Figure 2, to comprise the SCD file of 1000 IED, SCD file size is about 200M, when utilizing traditional means editor SCD file, uses internal memory more than 2G.
First in disk, open SCD file in SAX mode, now editing operation is not carried out to wherein IED; Secondly, comprise 100 IED according in every sub-SCD, splitting SCD file is 10 sub-SCD file; Then, antithetical phrase SCD file carries out editing operation one by one, and sub-SCD file small volume, opens internal memory also in tolerance interval.Adopt DOM mode to be loaded into sub-SCD file from disk, use for reference the operations such as traditional approach is edited it, added in internal memory, deletion, and preserve dom tree in the sub-SCD file of disk.
Treat that all sub-SCD file editors are complete, union operation is carried out to all edited sub-SCD file, obtain the SCD file of about 1000 new IED.
According to the method for decoupling zero, large SCD file is converted to little SCD file, decreases memory cost largely, and antithetical phrase SCD file editor decreases IED increases impact on SCD file volume.
Above embodiment can be completed by an instrument, can support that open multiple SCD edits preservation simultaneously, merges; Also can be coordinated by multiple instrument, Uncoupled procedure is responsible for by an instrument, and an instrument is responsible for editor and is preserved, and merging is responsible for by an instrument.
Above embodiment adopts the mode of carrying out decoupling zero with IED quantity.Such as:
Comprise the SCD file of 1000 IED, SCD file, according to SCL model, wherein contains 1 Header, 1 Substation, 1 Communication, 1000 IED, 1 DateTypeTemplates.
Be that publicly-owned element forms 12 sub-SCD file in conjunction with other elements with Header.
SUBSCD1 is formed by Header and 1 Substation;
SUBSCD2 is formed by Header and 1 Communication;
SUBSCD3 is formed by Header and 100 IED and 1 DateTypeTemplates;
……
SUBSCD12 is formed by Header and 100 IED and 1 DateTypeTemplates.
The sub-SCD file SUBCD3-SUBCD12 be made up of Header, IED, DateTypeTemplates is and carries out the decoupling zero mode of dividing into groups according to IED quantity.
As other embodiments, also decoupling zero, merging can be carried out according to other rules.
Be presented above the embodiment that the present invention relates to, but the present invention is not limited to described embodiment.Under the thinking that the present invention provides; the mode easily expected to those skilled in the art is adopted to convert the technological means in above-described embodiment, replace, revise; and the effect played goal of the invention that is substantially identical with the relevant art means in the present invention, that realize is also substantially identical; the technical scheme of such formation is carried out fine setting to above-described embodiment and is formed, and this technical scheme still falls within the scope of protection of the present invention.
