Background

Under the industrial 4.0 background, the automation and information technology is mature day by day, and the application market of the decentralized control system in China is moderately increased. Some problems have been found in long-term development applications. The picture development of a control system project needs to design and use pixels such as a flow chart of a project, a large number of physical schematic diagrams, a dynamic diagram in the process of project operation and the like. Many pixels are reused, but the attribute definition part of each pixel is different, and each pixel needs to establish a data link with the database data again to completely define the attribute again. When the engineering size is large, the search of the label point and the definition of the function of the pixel attribute become very complicated and time-consuming.

Disclosure of Invention

The technical problem to be solved by the invention is to provide an attribute definition method of a monitoring picture pixel, which is characterized in that a macro definition gallery is set and a reference index is established for similar pixels of an industrial monitoring picture, a character string representing a pixel attribute variable is marked, and the attribute modification of the pixel can be realized only by indexing the reference pixel and modifying the variable of the character string during later reference.

The invention is realized by the following steps: a method for defining the attribute of a monitoring picture pixel comprises the following steps:

step S1, predefining a marking mode of a script command character string of a pixel attribute variable in a source code, wherein the pixel attribute variable comprises a monitoring link point variable, a picture variable and an operation script command variable;

step S2, drawing the pixel combined by the basic graphics;

step S3, defining a corresponding script command for display and operation for each basic graph in the pixels, and labeling the character strings of the attribute variables of the pixels in the script command for display and operation according to the predefined labeling mode;

step S4, marking the integral definition category and index name of the pixel of the made character string, and then adding the integral definition category and index name into a pre-established macro definition gallery;

and step S5, when the pixels are to be referred by the later-stage monitoring picture, the actual definition of the pixel attributes can be completed only by referring the pixels by the index names and modifying the marked variables in the character strings of the script commands for display and operation.

Further, the labeling mode is as follows: and the character strings of monitoring link point variables, picture variables and operation script command variables are represented by head envelope and tail envelope of two # numbers.

Further, the basic graphics include lines, rectangles, ovals, rounded rectangles, bitmaps, and characters.

Further, the steps S3 to S5 are performed in the form of a pop-up dialog box, wherein the step S5 is to automatically list the variables marked up in the character string of the script command for display and operation through the pop-up dialog box, and pop-up a new dialog box for user modification after being selected.

The invention has the following advantages: the method comprises the steps of predefining a marking mode of a script command character string of a pixel attribute variable in a source code, marking the character string of the pixel attribute variable in a script command for display and operation according to the predefined marking mode, then integrally defining a category and an index name for a pixel, and adding the pixel into a pre-established macro definition gallery.

Detailed Description

In the field of automation control, during secondary development of monitoring configuration software, the shapes of picture example pixels corresponding to similar devices are the same, and the difference is that linked monitoring data or picture defined data are different, namely, attributes are different. Therefore, only partial modifications of these different points are considered. When the pixel is established, the different points which may appear are reserved as changeable attributes, and when the pixel is actually applied, the personalized attributes are changed.

Based on the above idea, please refer to fig. 1 to 5, the method for defining attributes of pixels of a monitoring screen according to the present invention includes:

step S1, pre-defining the labeling mode of the script command character string of the pixel attribute variable in the source code, wherein the pixel attribute variable comprises a monitoring link point variable, a picture variable and an operation script command variable. For example: the marking mode may be a character string of two # number head and tail envelope script commands, but the invention is not limited to this, and other marking modes may also be used.

Step S2, as shown in fig. 2, drawing a pixel composed of basic graphics in a picture by a mouse and a keyboard; the basic graphics include lines, rectangles, ellipses, rounded rectangles, bitmaps, characters, and the like.

Step S3, a script command for corresponding display and operation is defined for each basic graph in the pixels, such as the basic graph "text" in fig. 2 is defined as displaying the real-time database value, and the label point name is "rdb.

And then, according to the predefined marking mode, marking the character string of the attribute variable of the icon in the script command for display and operation so as to show the difference from the character string of the general script command. As shown in fig. 3, the variables of the monitoring link point, the different screen variables, and the different operation script commands of the basic graphic "text" are enveloped by two pound marks (#); for this basic graph "text", the variable of the monitoring link point is the number "001" of the device, so only "001" needs to be enveloped by # to be used.

Step S4, as shown in fig. 4, marks the whole of the pixel (in this embodiment, the whole of the pixel is composed of a rectangle, an ellipse, and a character "text") with the created character string, defines the category and the index name, and adds the category and the index name to the pre-established macro definition gallery.

Step S5, when the post-monitoring picture needs to refer to a pixel, as shown in fig. 5, the pixel can be found by inputting an index name, and the marked variables in the character string of the script command that is displayed and operated are automatically listed through the dialog box of the popup window, and can be modified one by one after selection, thereby completing the actual definition of the pixel attribute.

In the present invention, as shown in fig. 3 to 5, the operations in the steps S3 to S5 can be performed through a pop-up dialog box, which is not only convenient, but also less prone to error.

Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
