Parallel CIM/E file structured analysis method

Abstract

The invention discloses a parallel CIM / E file structured analysis method. The method comprises the steps of reading a CIM / E file to a computer memory; reading and cutting off a complete character string of an E file header element according to a CIM / E file specification; reading and cutting off an E file data block definition character string according to a CIM / E file specification; reading a datacontent character string of the data block; performing repeating until all element character strings of the whole CIM / E file are read, and storing related element character strings into character string fields of objectified hierarchical elements of the JAVA structure; utilizing a thread pool technology to analyze character strings of elements of each level of JAVA structure objectification in parallel, and differentially processing the character strings according to contents of data blocks and header elements in the analysis process; and finally, achieving parallel structured object analysisand assignment of the CIM / E file. According to the method, on the basis of structural object hierarchical description, all attributes and all numerical values are analyed in parallel by using a thread pool technology, and association of parsed data and a result object is achieved by virtue of structural description.

Description

technical field

[0001] The invention relates to a parallel CIM / E file structure parsing method, which realizes the high-speed parsing of the power system data model description CIM / E file, and satisfies the high-speed description application of the power system data model and the efficient exchange of a large amount of online data. Background technique

[0002] Power system data model description-E language specification (hereinafter referred to as "E language") is based on the object-oriented abstraction of the IEC61970301 power system common data model CIM, and is customized for the efficiency defects of CIM when it is described in XML. A new and efficient power system data model description language, the instance data formed by this language is a tokenized plain text data, which is called E-file in the power system. In the E file, the simple and complex data models of the power system are described concisely and efficiently through a small amount of markup symbols and gra...

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] 1. Analysis of CIM / E file format:

[0034] Refer to the relevant description of Power System Automation "Power System Data Model Description Language E", the common E file format is as follows:

[0035]

[0036] An example of the above E file format is as follows:

[0037]

[0038]

[0039] like figure 1 As shown, by analyzing the end line of the data block in the E file, it starts with , which contains the name of the data block and the name of the subject, which must be consistent with those in 2). Among them, there can be multiple data blocks in an E file, so the E file can be structured as follows:

[0040] 2. CIM / E file object structure representation, such as figure 2 shown:

[0041] 3. CIM / E file structure analysis process

[0042] like image 3 As shown, a parallel CIM / E file structure parsing method provided by the present invention incl...
