[0060] Embodiment 1

[0061] Reference Figures 1-3 As a first embodiment of the present application, the embodiment provides a method and system for dynamically adding graphic elements, comprising:

[0066] Further, the lower left corner point of the picture editing system display is selected as the origin, the horizontal and vertical edges of the picture editing system display passing through the origin are selected as the coordinate axes, a rectangular coordinate system is established, and the four corner points of the picture editor are (0, 0), (0, A), (B, A) and (B, 0), wherein A is the vertical length of the picture editing system display, and B is the horizontal length of the picture editing system display.

[0067] It should be noted that before the new picture element picture loading display is carried out, different category identification frames are established in different positions in the picture editing system according to the file category;

[0068] Further, if the file is a common category, the picture in the picture editing system is in the rectangular region formed by (0, 3A / 4), (0, A), (B / 2, A) and (B / 2, 3A / 4) as a common category picture element identification frame, and the common category picture element includes any picture element of the field device in the old scene;

[0069] Further, if the file is a special category, the picture in the picture editing system is in the rectangular region formed by (0, 0), (0, A / 4), (B / 2, 0) and (B / 2, A / 4) as a special category picture element identification frame, and the special category picture element includes any picture element in the new scene;

[0070] Further, if the file is a fault category, the picture in the picture editing system is in the rectangular region formed by (B, A), (B, 3A / 4), (B / 2, A) and (B / 2, 3A / 4) as a fault category picture element identification frame, and the fault category picture element includes all fault picture elements in the new and old scenes;

[0071] Further, if the file is a to-be-deleted category, the picture in the picture editing system is in the rectangular region formed by (B, A / 4), (B, 0), (B / 2, A / 4) and (B / 2, 0) as a to-be-deleted category picture element identification frame or / and corresponding deletion picture elements are established below different category picture elements, and the to-be-deleted category picture element includes all deleted, to-be-deleted picture elements in the new and old scenes and the combined picture elements of the corresponding deletion picture elements established below different category picture elements.

[0072] It should be noted that when it is judged that the user demand is a native picture element, it is determined that the picture element already exists, and the server is called to retrieve the picture element, and no picture element addition operation is performed;

[0073] It should be noted that when it is judged that the user demand is not a native picture element, it is determined that the picture element does not exist, and the server is called to retrieve the picture element editing program, and the picture element addition operation is performed;

[0074] It should be noted that when the picture element addition operation is performed, if the picture element editing program mode in the background real-time editing picture editing system is selected, the server is called to issue a background compiling instruction;

[0075] It should be noted that after the picture editing system obtains the background compiling instruction, the normal working state of the picture editing system is closed, the user demand information is transmitted into the picture element program, the new picture element program is generated, the new picture element program is compiled and built into a two-level dynamic link library file, and is placed in a specified folder, and the category of the new picture element is judged, and the picture element is placed in the corresponding picture element identification frame.

[0076] Further, if the new graphic element needs to be displayed or / and used, the picture editing system is restarted;

[0077] Further, if the new graphic element does not need to be displayed or / and used, and further new graphic elements need to be added, it is determined whether the new graphic element belongs to the native graphic element, and the server instruction is waited.

[0078] It should be noted that when the graphic element addition operation is performed, if the graphic element editing program mode in the foreground real-time editing picture editing system is selected, the server issues a foreground compilation instruction;

[0079] It should be noted that after the picture editing system obtains the foreground compilation instruction, the normal working state of the picture editing system is suspended, the user demand for adding graphic elements is determined, the corresponding graphic element identification frame position where the graphic element is placed is determined, and the interface function is called to create the new graphic element and configure the data of the new graphic element at the position on the suspended page. The new graphic element configuration data is encapsulated, and the encapsulated configuration data is associated with the new graphic element. The associated data is saved in the secondary dynamic link library file.

[0080] Further, if the new graphic element needs to be displayed or / and used, the suspended picture editing system is directly stopped, refreshed by the automatic refresh, and the new graphic element is displayed.

[0081] Further, if the new graphic element does not need to be displayed or / and used, the automatic refresh is closed, and the server instruction is waited.

[0082] It should be noted that the picture editing system includes that a picture in the picture editing system is composed of native graphic elements or / and custom graphic elements. The completed picture is saved in the form of an SVG file.

[0083] Further, when the picture is opened in the real-time picture display system, in addition to displaying the graphic element according to the configuration data, the real-time related measurement value of the measurement point can be obtained and the real-time control and adjustment operation of the measurement point can be performed according to the configured measurement point information.

[0084] Further, when the picture type of the graphic element is the operation pop-up picture of a certain measurement point, the custom graphic element can automatically obtain the ObjectId of the measurement point of the bound picture, so as to obtain the real-time related measurement value of the measurement point or perform the real-time control and adjustment operation of the measurement point in the future.

[0085] Further, the new added graphic elements include first-level graphic elements, second-level graphic elements and third-level graphic elements, the picture editing system displays only the first-level graphic elements, the second-level graphic elements are set as the embedded graphic elements corresponding to the first-level graphic elements of the corresponding categories, the third-level graphic elements are set as the embedded graphic elements corresponding to the second-level graphic elements of the corresponding categories, the original graphic elements are all first-level graphic elements, the horizontal length and the vertical length of the first-level graphic elements are B / 10 and A / 10 respectively, the horizontal length and the vertical length of the second-level graphic elements are B / 12 and A / 12 respectively, and the horizontal length and the vertical length of the third-level graphic elements are B / 14 and A / 14 respectively;

[0086] Further, the first-level graphic element establishment sequence and the new added graphic element picture loading and display sequence are as follows:

[0087]

[0088] It should be noted that the first-level graphic elements are established according to the matrix value increasing sequence, and the new added graphic elements are loaded and displayed according to the sequence establishment sequence, if the number of the original graphic elements and the new added first-level graphic elements is greater than 25, the original graphic elements are integrated and re-established according to the categories, and the second-level graphic elements and the third-level graphic elements are established according to the time sequence based on the establishment of the first-level graphic elements.

[0089] Further, the first-level dynamic link library file and the second-level dynamic link library file include, when the normally running picture editing system does not respond after the second-level dynamic link library file of the new added graphic element is added, or when the graphic element control is performed, it is judged whether the fault graphic element is an original graphic element;

[0090] It should be noted that if it is an original graphic element, the picture editing system is closed, the file corresponding to the graphic element in the first-level dynamic link library file is deleted, the corresponding original graphic element is newly established, the picture editing system program is restarted, and only the first-level dynamic link library file is connected, if the error no longer exists, the second-level dynamic link library file is connected;

[0091] It should be noted that if it is not an original graphic element, the corresponding graphic element below is directly clicked to delete the graphic element, after the server obtains the delete graphic element instruction, the file corresponding to the graphic element in the second-level dynamic link library file is deleted, and the picture editing system does not stop working in this process.

[0092] Further, the configuration interface can also complete the configuration work of the properties such as the color and font of the graphic elements.

[0093] It should be noted that since the graphic element program and the picture editing system program are two independent modules of calling and being called, the update of the graphic element program will not affect the picture editing system program, and at the same time, the update of the picture editing system program will also try to avoid the update of the graphic element program.

[0094] It should be noted that the picture editing system program is formed into a relatively stable executable file schemaker.exe through a series of repeated iterative processes such as editing, compiling, debugging, linking, etc. The program contains all the functions required for the editing of the computer monitoring picture of the hydropower station and embeds commonly used graphics.

[0095] It should be noted that the development of the custom graphics is independent of the picture editing system program, which can be developed by the same person at different times or by different persons at the same time or at different times. The graphics program also needs to go through a series of iterative processes such as editing, compiling, debugging, and linking.

[0096] Further, the dynamic linking process occurs during the running of the schemaker.exe, i.e. each time the picture editing system is opened and run, the system program needs to load the dynamic link library file of the custom graphics during runtime for the user to edit the picture using the graphics.

[0097] It should be noted that the linker program only records the names of the called functions in the graphics program and a small amount of registration information in the picture editing system program during linking, while the complete content of the dynamic link library is actually mapped to the virtual address space of the corresponding process during the execution of the picture editing system program (runtime). The linker program finds the corresponding function code according to the function information recorded in the picture editing system program beforehand.

[0098] Further, the picture editing system program automatically loads all dynamic link library files in the specified folder during runtime, so that the addition, modification, and deletion of graphics only need to add, update, and delete library files in the folder, without involving changes to the picture editing system program itself.

[0099] Further, the picture editing system program follows a modular design and designs specific interfaces for the development of the graphics program to facilitate graphics customization. When the system program runs, it dynamically loads the dynamic library under the specified directory and calls the interface functions in the dynamic library to implement the functions required by the graphics.

[0100] It should be noted that all graphics programs need to comply with the agreement and implement the specified function. To meet the needs of graphics, the main functions are as follows:

[0101] The function returns the icon, which is called when the picture editing system interface is initialized. After initialization, the graphics icon is displayed in the system interface.

[0102] The function returns the prompt information, which contains a brief introduction of the graphics. The prompt information is triggered when the function is called.

[0103] Returning the name of the function, the name and icon of the graph element are displayed together in the system interface, and the system interface is also called at initialization.

[0104] The function of creating a graph element, obviously the function is used to create a graph element, the parameters of the function include database instances, graph element configuration data, and graph element running environment, etc., and is called when the graph element is drawn and the screen is opened.

[0105] The function of popping up the configuration interface, the graph element is used as a medium for displaying measurement point data and operating and controlling the measurement point, and the work of binding the measurement point needs to be completed in the configuration interface. In addition, the attribute configuration of the graph element itself also needs to be completed in the configuration interface. The function is called when the operation of triggering the configuration pop-up window is triggered.

[0106] The function of returning configuration data, configuration data carries all the configuration information of the graph element, and will be used in multiple places, and the function will also be called in multiple places.

[0107] The function of adjusting the size of the graph element, the size of the graph element often needs to be adjusted according to the needs of the screen, and the function will be called every time the size of the graph element is adjusted, and adjusting the size of the graph source is invalid for the first-level graph element.

[0109] The first file library establishing module is used to obtain original graph elements by combining graph element editing programs according to historical hydropower station computer automatic monitoring data and hydropower station field device parameter information, and establish a first dynamic link library file;

[0110] The second file library establishing module is used to determine whether the user demand graph element is an original graph element, and to select a real-time editing screen editing system graph element editing program mode according to the demand, and to establish a second dynamic link library file;

[0111] The display module is used to load and display the newly added graph element screen according to the first dynamic link library file and the second dynamic link library file.

[0112] The above-mentioned each unit module can be embedded in or independent of the processor in the computer device in hardware form, or can be stored in the memory in the computer device in software form, so as to call and execute the operations corresponding to the above-mentioned each module by the processor.

The internal memory provides an environment for the operating system and the computer program in the non-volatile storage medium to run. The communication interface of the computer device is used for wired or wireless communication with external terminals. Wireless mode can be achieved through WIFI, operator network, NFC (near field communication) or other technologies. The computer program is executed by the processor to implement a method for dynamically adding a graph element. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen. The input device of the computer device can be a touch layer overlaid on the display screen, or a key, trackball or touchpad provided on the shell of the computer device. It can also be an external keyboard, touchpad or mouse, etc.

[0121]

[0122] The application provides a method and system for dynamically adding a graphic element, wherein when the graphic element is added, only the dynamic link library file obtained by compiling and constructing the graphic element program is placed in a specified folder; when the graphic element is deleted, only the dynamic link library file related to the graphic element in the specified folder is deleted. When the picture editing system program is edited, all the dynamic link library files in the specified folder are scanned and linked, and the addition or deletion of the graphic element does not cause the picture editing system to be re-edited or re-compiled.

[0123] The method of the application is based on the modular design of the picture editing system, and the dynamic addition of the graphic element is realized efficiently by using the dynamic link library file. Due to the characteristics of the dynamic link library, the graphic element program can be developed, debugged, compiled and constructed independently of the picture editing system program. The method for dynamically adding, modifying and deleting the self-defined graphic element at a very low cost can meet the needs of the diversification of the graphic element and customization in the picture display and picture editing program of the computer automatic monitoring field of the hydropower station.
