Description

TECHNICAL FIELD

[0001] The present application relates to the field of nuclear power plant instrument control software, in particular to a connection method based on model development programming tool. BACKGROUND

[0002] The development of nuclear power plant instrument control engineering application software generally uses graphical design method, and a program such as C can be obtained by compiling the model through a code generation tool. Therefore, a tool is needed to enable the user to interact with the graphical representation of the model, and then realize the graphical modeling method. The current popular programming method is based on text, mainly using a certain recognized programming language to model the system. In recent years, people have begun to realize that visualizing the software development method can greatly improve the software development efficiency. In many cases, the graphical representation is clearer, more intuitive, and closer to the actual demand. Through the graphical representation, the correlation, data flow and other information between them can be observed intuitively. However, such intuitive understanding cannot be achieved through text. The visual representation method has become the development trend of software development methodology, such as UML. The advantage of the visual system is that it can map the dry programming language syntax to the relationship between graphical objects, so that general technical personnel can understand the system without understanding the language syntax. To some extent, the threshold of programming design is reduced.

[0003] The present application only cares about the content related to the development of graphical modeling software, and does not include the conversion rules of graphics and text. For the development of graphical modeling software, many available programming frameworks can be used, such as QT, Eclipse, etc. Even if a general programming framework is used, we still need to solve the usability problem of the software. How to realize a simple, easy-to-use and powerful modeling software still requires developers to invest a lot of energy and creativity. The present application proposes an easy-to-use and feasible connection method for the connection requirement in the graphical modeling process. SUMMARY

If yes, the connection type between the first target pin of the first target connection figure and the second target pin of the second target connection figure is determined as S type or reverse S type; otherwise, the connection type between the first target pin of the first target connection figure and the second target pin of the second target connection figure is determined as L type or reverse L type.

[0070] In a possible implementation, the pre-deployed connection algorithm is scheduled to connect the first target pin and the second target pin according to the connection type between the first target pin and the second target pin of the second target connection figure, and includes the following steps.

[0071] When the connection type between the first target pin of the first target connection figure and the second target pin of the second target connection figure is L type or reverse L type, the first connection algorithm is scheduled to connect the first target pin and the second target pin.

[0072] When the connection type between the first target pin of the first target connection figure and the second target pin of the second target connection figure is S type or reverse S type, the second connection algorithm is scheduled to connect the first target pin and the second target pin.

[0073] As shown in FIG. Figure 3 The first connection algorithm includes the following steps.

[0074] Six base points are determined as a first base point P1, a second base point P2, a third base point P3, a fourth base point P4, a fifth base point P5, and a sixth base point P6.

[0075] The positions of the first base point P1 and the second base point P2 are determined as the first target pin position (x1, y1) of the first target connection symbol, and the positions of the fifth base point P5 and the sixth base point P6 are determined as the second target pin position (x2, y2) of the second target connection symbol.

[0076] The position of the third base point P3 is determined as ((x1+x2) / 2, y1), and the position of the fourth base point P4 is determined as ((x1+x2) / 2, y2).

[0077] The first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6 are sequentially connected to complete the connection.

[0078] As shown in FIG. 2B, the second connection algorithm includes the following steps. Figure 3 Six base points are determined as the first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6.

[0079] The position of the first base point P1 is determined as the first target pin position (x1, y1) of the first target connection symbol, and the position of the sixth base point P6 is determined as the second target pin position (x2, y2) of the second target connection symbol.

[0080] The position of the second base point P2 is determined as (x1+m, y1), the position of the third base point P3 is determined as (x1+m, (y1+y2) / 2), the position of the fourth base point P4 is determined as (x2-m, (y1+y2) / 2), and the position of the fifth base point P5 is determined as (x2-m, y1). Wherein m represents a preset position offset.

[0081] The first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6 are sequentially connected to complete the connection.

[0082] In a possible implementation, after the pre-deployed connection algorithm is scheduled to connect the first target pin and the second target pin according to the connection type between the first target pin and the second target pin of the second target connection symbol, the method further includes the following steps.

[0083]

[0084] ​When the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is L type or inverse L type, a first adjustment instruction of the first target pin position and / or the second target pin position generated by the human-computer interaction is accepted, and the first target pin position and / or the second target pin position is adjusted according to the first adjustment instruction, while the first base point P1 changes following the first target pin position and / or the sixth base point P6 changes following the second target pin position, and the positions of the remaining base points change following the first base point P1.

[0085] When the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is L type or inverse L type, a second adjustment instruction input by the human-computer interaction is accepted, and the horizontal coordinates of the third base point P3 and / or the fourth base point P4 change according to the second adjustment instruction.

[0086] When the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is S type or inverse S type, a third adjustment instruction of the first target pin position generated by the human-computer interaction is accepted, and the first target pin position is adjusted according to the third adjustment instruction, while the first base point P1 changes following the first target pin position, and the positions of the remaining base points change following the first base point P1.

[0087] When the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is S type or inverse S type, a fourth adjustment instruction input by the human-computer interaction is accepted, and the horizontal coordinates of the second base point P2 and / or the fifth base point P5 change according to the fourth adjustment instruction, and the third base point P3 and the fourth base point P4 change following.

[0088] When the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is S type or inverse S type, a fifth adjustment instruction input by the human-computer interaction is accepted, and the third base point P3 and / or the fourth base point P4 change according to the fifth adjustment instruction, and the second base point P2 and the fifth base point P5 change following.

[0089] For example, support pin position changes and control point changes to achieve flexible wiring and manual adjustment, the change rule is as follows: for L type, the movement includes: a, c) the starting pin moves, then P1 follows the starting pin, P3 follows the change of the vertical coordinate, the horizontal coordinate is unchanged, and the remaining points are unchanged. b, d) click the line to select the line, move the mouse to the vicinity of P3, P4, P3, P4 points can move along the X axis with the mouse, P3, P4 horizontal coordinate changes synchronously with the mouse position. The remaining points are unchanged. The movement of the end pin is similar to that of the starting pin, which is not described in detail. For S type connection, the movement includes: a) the starting pin position moves, P1 follows the change, P2 vertical coordinate follows the movement, horizontal coordinate is unchanged. b) the same as L type, P2 and P5 can move horizontally when selected by the mouse, P3 and P4 follow passively. c) P3 and P4 can move to any position with the mouse when selected by the mouse, P2 and P5 horizontal coordinates follow passively. The connection transformation is as shown in Figure 4 and Figure 5 .

[0090] In one possible implementation, after the pre-deployed connection algorithm is scheduled to connect the first target pin and the second target pin, according to the connection type between the first target pin and the second target pin of the second target connection symbol, it further includes:

[0091] Real-time detection of whether the first target pin position and / or the second target pin position changes, if so, extract the X axis coordinate x1 in the first target pin position, and extract the X axis coordinate x2 in the second target pin position, otherwise continue to monitor.

[0092] Determine whether the X axis coordinate x1 in the first target pin position is greater than or equal to the X axis coordinate x2 in the second target pin position, if so, determine that the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is S type or reverse S type, otherwise determine that the connection type between the first target pin of the first target connection symbol and the second target pin of the second target connection symbol is L type or reverse L type.

[0093] For example: when the relative position of the pin changes, the connection mode is checked, and the line type is automatically switched to re-layout. The conversion logic is as follows: if the connection type is L type before moving, when the pin position changes after moving the pin, x1 >= x2, then trigger linear switching, and generate S type connection again. If the connection type is S type before moving, the line type will not change when the position changes, because S type is more complex than L type, and has higher plasticity, which can be adjusted manually to realize L type connection. Conversely, it cannot.

[0094] Since the same algorithm is used in the connection algorithm, it is difficult to distinguish the line when connecting the parallel pins of the same symbol. Therefore, a new connection calculation method is proposed to solve this problem. Here, the number of symbol input pins and output pins n and the pin index i of the current connection are introduced. According to the pin index, the line is indented to separate the overlapping lines, as shown in Figure 6 .

[0095] In one possible implementation, the first connection algorithm includes:

[0096] The total number of pins n of the first target connection symbol and the pin index i of the first target pin are obtained, and six base points are determined, i.e., the first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6.

[0097] The positions of the first base point P1 and the second base point P2 are determined as the position (x1, y1) of the first target pin of the first target connection symbol, and the positions of the fifth base point P5 and the sixth base point P6 are determined as the position (x2, y2) of the second target pin of the second target connection symbol.

[0098] The position of the third base point P3 is determined as ((x1+x2)*(0.3+(0.4*i) / (n+1)), y1), and the position of the fourth base point P4 is determined as ((x1+x2)*(0.3+(0.4*i) / (n+1)), y2).

[0099] The first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6 are sequentially connected to complete the connection.

[0100] For S-type connection, the derived connection style shown in Figure 7 can be achieved by moving the control point to avoid obstacles in the S-type connection path.

[0101] In one possible implementation, the second connection algorithm includes:

[0102] The total number of pins n of the first target connection symbol and the pin index i of the first target pin are obtained, and six base points are determined, i.e., the first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6.

[0103] The position of the first base point P1 is determined as the position (x1, y1) of the first target pin of the first target connection symbol, and the position of the sixth base point P6 is determined as the position (x2, y2) of the second target pin of the second target connection symbol.

[0104] The position of the second base point P2 is determined as (x1+m(1+f*i), y1), the position of the third base point P3 is determined as (x1+m(1+f*i), (y1+y2) / 2), the position of the fourth base point P4 is determined as (x2-m(1+f*i), (y1+y2) / 2), and the position of the fifth base point P5 is determined as (x2-m(1+f*i), y1). Here, m represents the preset position offset, and f represents the indentation coefficient.

[0105] Connect the first base point P1, the second base point P2, the third base point P3, the fourth base point P4, the fifth base point P5, and the sixth base point P6 in sequence to complete the connection.

[0106] In one possible implementation, it also includes:

[0107] Provide staff with a free-form polyline mode, and in the free-form polyline mode, accept multiple continuous control points input by the user through human-machine interface.

[0108] For any two adjacent control points, connect them using mode A, mode B, mode C, or mode D.

[0109] Mode A is a horizontal right-angled line, Mode B is a vertical right-angled line, Mode C is a horizontal line, and Mode D is a vertical line.

[0110] It also supports custom free-form polylines, which consist of a list of control points. Clicking the starting pin enters connection mode; in this mode, each click generates one or two control points, until the ending pin is clicked. Free-form polylines are drawn by connecting all control points. The drawing method is as follows: Free-form polyline drawing modes include... Figure 8 There are four drawing modes: A) Horizontal Right Angle, B) Vertical Right Angle, C) Horizontal Line, and D) Vertical Line. The control point calculation method for mode A is: P2' = (x2, y1), where P1 and P2 are the mouse click positions. The control point calculation method for mode B is: P2' = (x1, y2), where P1 and P2 are the mouse click positions. The control point calculation methods for modes C and D are: P1 and P2 are the mouse click positions. During the drawing process, the drawing mode will switch between ABCD based on the positions of two mouse clicks to achieve a more reasonable polyline.

[0111] The switching logic is: the start pin uses A mode (i.e. initialized as A mode), when the first click position of the mouse is at the same horizontal position as the initial pin, the current uses C mode to draw. If the first click position of the mouse is at the same vertical position as the initial pin, the current uses D mode to draw. Otherwise, A mode is used to draw. In the process of continuing to connect, if the same horizontal is C, the same vertical is D. Otherwise, if the last time uses C, the next time uses B, if the last time uses D, the next time uses A, otherwise, the last mode is continued. The drawing mode conversion example is as follows: Figure 9 .
