Embodiment
Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that ability
The technical staff in domain can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
It is fixed.
As shown in figure 1, a kind of grid model data maintenance management method based on CIM/E files, comprises the following steps：
Step 1, by CIM/E file interfaces maintenance tool, (DBI of such as Guodian Nannui Tech Co., Ltd is soft
Part) operation content is sent to file service and the change to safeguarding CIM/E files under state is completed by file service.
The maintenance management method of the present invention is divided by carrying out " state " to grid model data CIM/E files, and setting is safeguarded
Flow, i.e., in the present invention, CIM/E files have two kinds of states, are to safeguard state and run mode respectively.CIM/E files are under both states
There are different entities, i.e. off-line files respectively and in line file.Inquiry and maintenance of the user to grid model data are being safeguarded
Completed under state, access is to safeguard the CIM/E files under state.After user confirms that attended operation is errorless, it will can safeguard under state
CIM/E file synchronizations to run mode.And other application obtains model data and completed under run mode, access is run mode
Under CIM/E files.
Step 2, by CIM/E file interfaces maintenance tool issue check command, and by background verify service to dimension
CIM/E files are verified under shield state, step 3 are entered if upchecking, otherwise, verification reports an error.
Grid model data CIM/E file verifications include 3 levels：The verification of file authentication, file format verification, text
Part content authentication.First, file authentication verification refers to whether file content is to be read and write by CIM/E file standards interface,
Either with or without the write operation for carrying out non-standard interface.File authentication is verified as：CIM/E files are calculated by using MD5 algorithms
The MD5 codes of one 16, by using the comparison of MD5 codes, to check whether file illegally or is by mistake changed.
The verification of CIM/E file formats refers to the verification of grid model data CIM/E file labels and criteria check, passes through mark
Quasi- CIM/E file interfaces are written and read file, can produce a series of file label and fixed form.By these labels and
Form could correctly resolution file content, so criteria check and label verification are to ensure that CIM/E file contents are correctly weighed
Want a step.
The verification of CIM/E file contents refers to file content as the basis of support electric power dispatching system each business operating
Whether whether information meets logic, data reasonable.It can be avoided by file content verification because irrational model data causes
The problem of other application module produces mistake.
Step 3, CIM/E file interfaces maintenance tool issue operation synch command, background synchronization service will be safeguarded under state
CIM/E files under CIM/E file distributions to run mode, realize the synchronization of CIM/E files, and step 4 is entered after synchronously completing.
It is preferred that, it is from the off-line files of file server host to file server master first when carrying out file synchronization
The online file synchronization of machine, carries out judging synchronously whether succeed, if it is successful, again by text after synchronously completing by comparing MD5 codes
Part server host is synchronized to each file server standby host, then carries out file synchronization judgement by MD5 codes again, if
The fully synchronized success of each node then this time file synchronization success, otherwise re-starts file synchronization.As shown in Fig. 2 being node
Between off-line files, the synchronous schematic diagram in line file.
Step 4, CIM/E file interfaces maintenance tool issue the order that comes into force, and file, which comes into force, to be serviced the CIM/E under run mode
File distribution, which updates, arrives shared drive, and other application module is connected to after order reads newest model data from shared drive again
Information and load come into force.
May occur to change the situation that mistake, accidental damage etc. are difficult to recover, version when operating CIM/E files
The purpose of this management be exactly CIM/E files can be carried out when occurring above-mentioned fortuitous event from old version before it is extensive
It is multiple.Therefore, before being modified to CIM/E files, CIM/E files are first subjected to old version preservation.This work(can effectively solve the problem that
The difficulty of CIM/E file access patterns, improves the safety and reliability of maintenance during unexpected generation.The history version of CIM/E files
This preservation is to carry out the file content before file modification each time, as long as memory space is supported, the old version of CIM/E files
The preservation and recovery of all old versions can almost be supported.
By the way that grid model data CIM/E files are divided into line file and off-line files, and the maintenance of design safety
Mechanism and multi-level ground method of calibration, it is ensured that the correctness and reliability of data file.The file synchronization mechanism of formulation ensures
The uniformity of data on each machine node.The management of file multi version significantly reduces data recovery when fortuitous event occurs
Difficulty.The foundation, change and issue that the present invention can meet intelligent grid Dispatching monitor and control system model data are used, with logical
With property and validity.
The preferred embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure that bright specification and accompanying drawing content are made either equivalent flow conversion or to be directly or indirectly used in other related
Technical field, be included within the scope of the present invention.
