Obviously, the described embodiments It is a part of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present disclosure.

The inventor discovered through research that, in the related art, when manually drawing electrical diagrams using screens of different sizes for display, there is often a problem of size mismatch, resulting in that the electrical diagram cannot be clearly displayed on the screen.

According to this, the present disclosure provides a scheme in which the electrical diagram can be matched with the screen size.

FIG. 1 shows a schematic flowchart of an electrical diagram generation method according to an embodiment of the present disclosure. In some embodiments, the following electrical diagram generating method steps are performed by the electrical diagram generating apparatus.

In step S101: obtain the size of the screen and the node information of each node that needs to be displayed. The node information includes the type, level and parameters of the node.

In step S102: the corresponding model is called from a preset database according to the type and level of the node.

In some embodiments, the model stored in the preset database may be SVG (Scalable Vector Graphics). SVG is used to describe two-dimensional vector graphics, developed by the World Wide Web Consortium, and is an open standard.

Figures 2 to 4 show schematic diagrams of meter node models of some embodiments of the present disclosure.

Figures 2 to 4 show the model diagrams of the first-level meter nodes, the second-level meter nodes and the third-level meter nodes drawn by SVG. Figure 2 shows the model diagrams of the first-level meter nodes. No.XXX represents the node name. Ia, Ib, and Ic represent a-phase current, b-phase current, and c-phase current, respectively, and P represents power. Figure 3 shows the model diagram of the second-level meter node. No. XXX represents the node name, Ia, Ib and Ic represent the a-phase current, b-phase current and c-phase current, P represents the power and U represents the voltage. Figure 4 shows the model diagram of the three-level meter node. No. XXX represents the node name, and Ia, Ib, and Ic represent the a-phase current, b-phase current, and c-phase current, respectively. In some embodiments, the corresponding names and parameters may be stored in SVG XML (eXtensible Markup Language, Extensible Markup Language) files. SVG is scalable and can be customized for vector-based graphics. In some embodiments, when one page is displayed, it can be displayed up to three levels. If there are many first-level and second-level nodes, one page is displayed to the second-level nodes or even the first-level nodes.

In step S103: according to the size of the screen, the model of each node and the corresponding parameters are displayed on the page.

In some embodiments, the number of nodes displayed on each page is determined according to the size of the screen and the size of the model. According to the number of nodes displayed on each page and the parameters of each node, the model and corresponding parameters of each corresponding node are displayed on each page. It should be noted that the content displayed on the screen each time is regarded as a display page.

In some embodiments, the number of node displays is determined according to the ratio of the size of the screen to the size of the model. For example, the number of nodes displayed per page can be determined according to the following formula:

Among them, w ₁ is the size of the screen, w ₀ is the size of the model, the above-mentioned size can be width or height. n is the number of nodes displayed per page, k is a constant greater than 1, the function

Is the rounding function up. For example, for screen sizes with resolutions of 800 × 600, 1024 × 768, and 1920 × 1080, the number of nodes displayed per page can be 5, 7, and 9, respectively.

In some embodiments, according to the number of nodes displayed on each display page, the models corresponding to the first-level nodes and the second-level nodes are displayed through the first display page, and the models corresponding to the third-level nodes are displayed through the second Display the page to display.

Therefore, according to the size of the screen, each node that needs to be displayed can be displayed in pages, thereby ensuring that the display content of each page can be clearly displayed on the screen.

In step S104: obtain the connection relationship between each node.

In some embodiments, in the process of generating the electrical diagram, for the first-level nodes, the second-level nodes, the third-level nodes, etc., a tree-like form may be used for data storage, and a corresponding parent node and child node are configured for each node Therefore, the parent node and the child node are used to characterize the connection relationship between each node. For example, in order to configure a parent node and a child node for each node, it can be determined that the parent node of the highest-level node is empty and the child nodes of the lowest-level node are empty according to the level of the node.

For example, if the node has only three levels, the parent node of the first-level node is set to null, and its child nodes are connected second-level nodes. The parent node of the second-level node is the connected first-level node, and its child node is the connected third-level node. The parent node of the third-level node is the connected second-level node, and its child nodes are set to empty.

In the above embodiment, FIG. 2 shows a model schematic diagram of a first-level meter node, FIG. 3 shows a model schematic diagram of a second-level meter node, and FIG. 4 shows a model schematic diagram of a three-level meter node. Correspondingly, corresponding sub-nodes can also be set for the three-level ammeter node, so as to obtain the four-level ammeter node. Corresponding sub-nodes can also be set for the four-level ammeter node to obtain the five-level ammeter node. And so on.

In step S105: according to the connection relationship between each node, the model displayed on the page is connected accordingly.

In some embodiments, the model stored in the preset database may be SVG (Scalable Vector Graphics, scalable vector graphics). SVG is used to describe two-dimensional vector graphics, developed by the World Wide Web Consortium, and is an open standard.

In step S203: according to the size of the screen and the size of the model, determine the number of nodes displayed on each display page. It should be noted that the content displayed on the screen each time is regarded as a display page.

In some embodiments, the number of node displays is determined according to the ratio of the size of the screen to the size of the model. For example, the number of nodes displayed per page is determined by using the above formula (1).

In step S204: according to the node display number of each display page, a predetermined number of nodes associated with each display page are selected from the various nodes, where the predetermined number does not exceed the node display number.

In step S205, on the current page of the screen, the model and parameters corresponding to the nodes associated with the current page are displayed.

For example, you can select the middle point at the top of the page as the starting coordinate, and select the corresponding node tile from the standard tile resource library to draw the first node according to the first-level node type set by the user, and use the first node as the root node. Next, draw the second-level nodes under the first-level nodes in sequence, and the third-level nodes under the second-level nodes.

Next, the electrical diagram generating device sequentially draws the second-level nodes under the first-level nodes, and the third-level nodes under the second-level nodes, and finally draws the connection lines between the nodes uniformly to form a complete electrical diagram.

The input unit 601 is used to obtain the size of the screen and the node information of each node that needs to be displayed. The node information includes the type, level, and parameters of the node. For example, the type and level of the node are specified by the user and input into the electrical diagram generating device through the input unit 601.
