Power scheduling graphics system is at original SD-6000, on the basis of the exploitation of OPEN-2000 EMS and engineering experience, according to current scheduling automated system development trend, and in conjunction with domestic electrical traffic department actual requirement, develop a set of based on up-to-date standard, adopt more advanced technology, meet the forth generation dispatch automated system of higher requirement, but temporarily do not possess GIS function in this power scheduling graphics system, communicated in power scheduling graphics system with generalized information system by asynchronism callback mechanism, on the basis not increasing electric power Dispatching Drawings system loading, expand the function of power scheduling graphics system, enhance the flexibility of power scheduling graphics system.
Summary of the invention
The technical problem to be solved in the present invention is the Real-time Communication Technology of generalized information system and power scheduling graphics system, meets the needs of dispatch automated system to generalized information system.
For solving the problem, the invention provides a kind of generalized information system based on asynchronism callback mechanism and power scheduling graphics system communication means.
This method summary of the invention comprises:
(1), power scheduling graphics system calls generalized information system function;
(2), according to input parameter create corresponding GIS callback function class object, and complete the generation of GIS end function;
(3), power scheduling graphics system shows GIS callback function.
The process of above-mentioned steps (1) is as follows:
(1a) power scheduling graphics system picture properties, is built;
(1b) power scheduling graphics system primitive attribute, is built;
(1c), call parameters is assembled;
(1d), power scheduling graphics system calls generalized information system function.
The process of above-mentioned steps (2) is as follows:
(2a), call parameters is resolved;
(2b), instantiation GIS adjusts back class object;
(2c), according to call parameters demand, set up GIS and hold function.
The process of above-mentioned steps (3) is as follows:
(3a), the interfaces such as GIS menu, GIS toolbar are built according to GIS callback function return parameters;
(3b), scalable pel is generated in real time according to GIS callback function return parameters;
(3c), generate by the list of frame selection of land reason primitive information according to GIS callback function return parameters.
The communication mode of method of the present invention is a kind of method of calling of loose coupling, directly do not bind between power scheduling graphics system and generalized information system, after power scheduling graphics system has started just according to practical application need call GIS and adjust back class function, this method not only reduces the start-up time of power scheduling graphics system, and extend the function of power scheduling graphics system, add the flexibility of power scheduling graphics system.
In above-mentioned steps (3), adjust back class object according to the parameter instantiation GIS of input and generate corresponding GIS function and refer to that the GIS needed for the actual demand D ynamic instantiation of power scheduling graphics system adjusts back class object, this is a kind of communication mode of loose coupling.The advantage of the method has: one, GIS adjusts back the instantiation of class is in the real time execution of graphics system, shortens the initiating switchup time of power scheduling graphics system; Two, the instantiation of GIS readjustment class depends on the practical application request of power scheduling graphics system, the readjustment of generalized information system and actual demand close association.
In above-mentioned steps (4), power scheduling graphics system shows GIS callback function, and the parameter namely returned according to GIS callback function builds the graphing capability possessing geographical feature.Function comprises: one, create the interfaces such as GIS menu bar, GIS toolbar, the method extends the function of graphics system, defines the operation interface with GIS feature; Two, along with the real-time convergent-divergent of geographical map medium scale, dynamic realtime changes the size of pel, and the resolution of itself and background video figure is consistent, and the method makes visual effect more true to nature; Three, on the true geographical map with practical significance, carry out frame selection operation, the method can promote Consumer's Experience.Show the more closer to reality world according to the figure that GIS callback function generates, also more meet behavior and the operating habit of user.
Compared with background technology, beneficial effect of the present invention is: 1, under the prerequisite not increasing system complexity, expanding system function; 2, improve the flexibility of system, can customize the whether loading of GIS function.
