Technical Field

The invention belongs to the technical field of power grid dispatching automation, and particularly relates to a distributed graphic version management system and method suitable for a network.

Background

The automatic power grid dispatching system undertakes very important work such as power grid maintenance, power grid monitoring, dispatching operation and the like. The graph version management technology provides a management method and a visualization tool for unified maintenance and display of the power grid graph model for a dispatching automation system, effectively constructs, manages and displays graph files of different systems and different scenes, and a user realizes the tracing and analysis of the model version and section data change by looking up the graph files of different versions.

Currently, the mainstream file version management technology mainly includes an exclusive mode, a third party control mode, and the like. The exclusive mode adopts a file sharing mode, all files are stored on a common server, and different users access or operate the shared files under the corresponding permission constraint. However, when one user operates a certain file, the file is locked, other users only have read permission for the file temporarily, and the server performs unlocking processing after the user operation is finished, so that subsequent users can continue to operate the file conveniently. The third-party control mode adopts third-party control tools such as GIT, SVN and the like, the tools can track all files on the server, support multiple users to simultaneously operate the same file, and automatically and manually solve the conflict generated by simultaneously modifying the file by using a corresponding algorithm.

In the exclusive mode, the operation of the user on the file does not conflict, and the file can be modified by only one user at a time, but the mode has the biggest defect that a plurality of users cannot modify the file at the same time, so that the efficiency of file operation management is greatly reduced. The third-party control mode can overcome the defect that the exclusive mode cannot be operated concurrently, and improves the efficiency of file management, but the mode requires a user to independently install a client and a server of the third party, increases the complexity of project deployment, is not good in compatibility with the existing project in the field of power grid dispatching, and has potential safety hazards.

With reference to the second aspect, further, if the modification time of the graphic file on the graphic file server is inconsistent with the modification time of the corresponding graphic file on the graphic client and the graphic file on the graphic client has no modification identifier, the version of the graphic file on the graphic file server is considered to be new; if the modification time of the graphic file on the graphic client is consistent with that of the corresponding graphic file on the graphic file server, but the graphic file on the graphic client has a modification identifier, the version of the graphic file on the graphic client is considered to be new, and if the modification time and the file name of the graphic file on the graphic client are the same as those of the corresponding graphic file on the graphic file server, the versions of the graphic file on the graphic client and the corresponding graphic file on the graphic file server are considered to be consistent.

Detailed Description

To further describe the technical features and effects of the present invention, the present invention will be further described with reference to the accompanying drawings and detailed description.

The invention provides a distributed graph version management method suitable for a network, and FIG. 1 is a graph browsing tool drawing process, when a user browses a graph file, a browsing tool firstly obtains modification time, file name and file content of the file at local and network sides respectively, and carries out version comparison, and if the network is new or only the network according to the version comparison result, the browsing tool reads and displays the file content at the network side; if the local file is new, only local and consistent in version, the browser tool reads the content of the local file and displays the content; if the versions cannot be compared, the browsing tool reads the contents of the network files and displays the contents of the network files based on the network side graphic files.

FIG. 2 is a flow chart of a graphic editing tool for modifying a graphic, which comprises two parts of open drawing modification and saving. The opening flow is similar to that of a browsing tool, and after the versions of the graphic editing tool are compared, a user can select to open a local or network side graphic file according to a comparison result. When the user graph is modified, the graph file needs to be stored, the storage is divided into local storage (a graph client) and network storage (a graph file server), the local storage firstly stores the modified graph only in the local, the original file time is not modified, only a local modification identifier is added in a file name, the local graph file is generated, meanwhile, the version comparison is carried out on the local graph file and the network side, and the comparison result is displayed in an editing tool. The network saving process is similar to local saving, and file generation and version comparison are also performed, but the network saving generates the graphic file at the local side and the network side simultaneously.

Fig. 3 is an example of a browsing tool opening a graphic file, and when the browsing tool displays the graphic file after the opening is completed, the browsing tool displays the version comparison result of the graphic file at the lower left of the browsing tool.

Fig. 4 and 5 are examples of the editing tool opening and saving a graphic file, and similar to the browsing tool, the upper left of the editing tool after opening the drawing displays the comparison result of the version, and after the graphic modification is completed, the user can select local or network saving to store the file. After the graph modification is finished, the user selects a storage mode, and the graph file is only stored locally or updated locally and simultaneously through the network. In the saving process, the graphic editing tool can re-compare the version states of the current files on the local side and the network side (preventing the files on the network side from changing during drawing), and after the saving is finished, new version comparison information is displayed.

By using the distributed graphic file management method, the electric network automatic dispatcher can accurately master the current state of each graphic file, avoid the disordered pictures when multiple users operate the same graphic file at the same time, effectively reduce the electric network accidents caused by graphic abnormality, simplify the graphic maintenance difficulty of the electric network dispatcher, and greatly improve the drawing accuracy and efficiency.
