Detailed Description
The objects, technical solutions and advantages of the present invention will become more apparent by the following detailed description of the present invention with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a system tool design scheme based on a variable box is implemented according to the following steps:
1) Setting an operation interface, taking the operation interface as canvas, preparing for layout of interface graphic elements (buttons, drop-down frames, custom graphic objects and the like), and registering the operation interface in a variable box.
2) And carrying out region division on the plug-in modules, wherein region configuration exists in the form of configuration files, and the plug-in containers sequentially load service module plug-ins according to the configuration files. The module plugin is registered with the plugin container invention in the initializing process, and receives the call and management of the plugin container.
3) The variable box is a variable container, and the plug-in module registers itself in the variable box at the time of registration. And the global variable generated in the process of completing the self initialization of the plug-in module is also registered in the variable box.
4) The UILayout service fetches the operation from the box of variables according to the layout configuration file, fixes the required graphic elements to the corresponding positions, and then redraws the operation interface. The Connectslot service process binds the response event of the graphic element on the operation interface to the user input with the corresponding event action in the form of a signal-slot according to the configuration file.
The content in the tool is abstracted into graphic elements, operations, business objects and data. The data originates from a database, a configuration file, external interactions, etc. The dataflow diagram is shown in fig. 3.
The operation interface in step 1) exists in the form of a single instance. The operator interface may be a blank interface without any graphical elements or may have an initial layout, as shown in fig. 2. The menu bar, status bar and central work area dock component on the operation interface all have unique representation ID, and the existing graphic elements also have unique ID identifiers which are consistent with the corresponding graphic element IDs in the UI configuration file. The UILayout service loads the UI configuration file, takes out the graphic element corresponding to the ID from the variable box, and sets the interface layout according to the layout style in the UI configuration file.
The region division in the step 2) refers to that according to the functional independence and the interdependence of the plug-in modules, the loading priority of the plug-in modules is divided, and the plug-in modules with the same level are divided into the same region, namely under the same catalog. The configuration file specifies the order in which plug-ins are loaded by the plug-in containers according to the region division. The plug-in container is a plug-in module management module, and the call and the management of the plug-in module are realized through a unified interface. The plug-in container maintains a plug-in list, registers the plug-ins which have been loaded into the plug-in list, and then calls an initialization function according to an initialization sequence to initialize the plug-ins. The plug-in module must have a unique identification.
The plug-in container requires that the service module must support three interfaces, the interface functions are: 1) Finishing self-initialization and initializing global variables in the module; 2) Completing the connection between the plug-ins; 3) To begin providing services or functions.
The variable box in step 3) is a container class that provides interfaces for adding, deleting and looking up variables. The variable box maintains an instance copy of the variable held in the container and adds a variable call lock to secure the thread during a read operation of the variable. A list of < kdy, value > key value pairs is maintained in the variable box, the key is a unique identification name of the variable, the value is a value corresponding to the variable, the type of the value can be various types such as a pointer, a character string, an integer, an object and the like, and global variables used in the tool are stored, and the method comprises the following steps: profile names, profile formulation directories, database connection information, interface layout information, business objects, etc.
In the step 4), the UILayout service is mainly responsible for constructing the structure and layout of the function menu bar in the tool, and uniformly codes all interface elements in the operation interface to determine the unique identifier. Matching the identifier with the corresponding graphical interface in the configuration file, organizing the structure according to the hierarchical structure configured in the configuration file, and replacing the specific position in the operation interface. And simultaneously, the Connectslot service binds the corresponding event of the graphic element and the corresponding event action according to the connection configuration file. The tool is reached to make corresponding logic operation for the input operation of the user.
After the framework is built through the step 4, when the tool is started, the basic service automatically operates to provide service, and a user can interact with the system or the tool through an operation interface, wherein the operation interface is shown in fig. 3.
Through the scheme, the development of all subsystems and tools thereof in the intelligent management and control platform of the transformer substation can be same as that of adopting the design scheme, and different tools in the operation period and the configuration period can adopt the same framework, and only different plug-in modules are required to be developed according to different services. The basic service modules such as the real-time library module, the communication module and the like can all adopt the same framework. Therefore, the tool development period can be shortened, only one set of basic service module is required to be maintained, the maintenance cost is reduced, and unified management is facilitated.
