Description

TECHNICAL FIELD

[0002] The application running in the processing unit of a nuclear power plant is a high-safety application. For such a high-safety application, a modeling application (tool) that has been verified by an authoritative organization is used in engineering design to complete graphical model design, and then automatically generated and compiled into an execution program. The execution program that has been verified is safe and reliable, so as to run in a distributed control system (DCS) environment.

[0003] The output of the modeling application directly interacting with the designer is in the form of a model graph. For a high-safety DCS system, the model graph after the application logic conversion is complex. In order to facilitate later VV, testing, and maintenance, etc., the generated model graph is required to have the characteristics of accuracy, intuitiveness, simplicity, and readability. In the engineering design process of the DCS system, the model graph is designed on a drawing, and dozens to thousands of model graph elements are often laid out on a drawing, and the designer will frequently edit and design on the model graph, so there is a lot of graph element position editing work. In the graph element position editing process, the requirement that the graph element objects do not overlap each other and are reasonably laid out needs to be met.

[0004] However, the modeling application allows model graph elements to overlap in model editing, which makes it difficult for the output model graph to meet the requirements of clarity, simplicity, and easy maintenance. Therefore, the layout of the model graph needs to be adjusted manually by the designer, which not only increases the risk of model design errors, but also sharply increases the cost of model design, resulting in low modeling efficiency.

DETAILED DESCRIPTION

[0021] The application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict.

[0022] In the embodiments of the application, the modeling application is a computer application specially used for creating, editing, analyzing and verifying models. The modeling application can be applied in engineering, science, business and other fields to realize simulation of field data and understanding of behaviors of complex systems or processes.

[0023] Taking the instrument control system of a nuclear power plant as an example, the modeling application can be used in the system design stage, system debugging stage and operation and maintenance stage of the nuclear power plant. In the system design stage, the modeling application can be used to simulate and verify the functions of a large number of sensors, controllers and actuators and the like, and to assist in device selection. In the system debugging stage, the modeling application can perform fault injection and diagnosis testing and parameter optimization adjustment. In the operation and maintenance stage, the modeling application can perform device performance monitoring and prediction, and can also assist in operation training and exercises and the like.

[0024] The modeling application can construct and edit models, where a model is an abstract representation of a real-world system or process, which can be a mathematical model, a physical model, a logical model, etc. These models are created, modified, simulated and analyzed through modeling tools to help users better understand the characteristics, behavior and performance of the system, and to make predictions and optimizations.

[0025] For example, the application running in the processing unit of a nuclear power plant is a high-safety application. For such high-safety application, an authority-recognized modeling application (tool) is used in engineering design to complete graphical model design, and then automatically generated and compiled into an execution program. The execution program after verification can prove to be safe and reliable, so as to run in a distributed control system (DCS) environment.

[0026] The model represented by a graphical representation can be referred to as a graphic element. A graphic element is a graphical component or symbol used to construct a model. The graphic element is a basic building block in a graphical modeling tool, and by combining these graphic elements, users can create more complex system models. Different modeling software and fields can have different graphic element types. For example, according to geometric shape classification, graphic elements can include rectangular graphic elements, circular graphic elements, line graphic elements, etc. According to function classification, graphic elements can include sensor graphic elements, controller graphic elements and actuator graphic elements, etc.

[0027] The output of the modeling application directly interacting with the designer is in the form of a model diagram. For a high-safety DCS system, the model diagram after conversion of the application logic is complex. In order to facilitate later VV, testing and maintenance and the like, the generated model diagram is required to have the characteristics of accuracy, intuitiveness, simplicity and easy-to-read. In the DCS system engineering design process, the model diagram is designed onto a drawing, and a page of drawing often has tens to thousands of model graphic elements laid out, and the designer will frequently edit and design on the model diagram, so there will be a large amount of graphic element position editing work. In the graphic element position editing process, the requirement of not overlapping each other and reasonable layout of the graphic element objects is to be met.

[0028] However, the modeling application allows model primitives to overlap in model editing, resulting in the output model diagram being difficult to achieve clarity, simplicity and maintainability. Therefore, the layout of the model diagram needs to be adjusted manually by the designer, which not only increases the risk of model design errors, but also dramatically increases the cost of model design, resulting in low modeling efficiency.

[0029] To solve the problem of low modeling efficiency caused by the overlap of primitives in the modeling application, based on the actual design and requirements of the current nuclear power plant DCS system, combined with the high safety and high reliability requirements of the running application in the DCS system, and the characteristics of the high-frequency editing of the running logic model, aiming at the requirement of the nuclear power plant DCS system that needs to design a model diagram with high utilization value, low design cost, accuracy, simplicity and easy maintenance, a modeling application primitive collision data processing method is provided in some embodiments of the present application, as shown in Figure 1 、 Figure 2 The method comprises the following steps: S101, collision data of a target primitive is established.

[0030] The modeling application can execute model establishment, modification, deletion and other editing operations in response to user input control instructions, wherein some editing operations will cause the position or shape of the loaded model primitive in the modeling space to change. The control instructions corresponding to these editing operations can be referred to as model editing instructions. The primitive targeted by the model editing instruction is referred to as the target primitive, i.e. the target primitive is the primitive whose position changes in the modeling space of the modeling application.

[0031] In response to the editing operation performed on the model primitive in the modeling space of the modeling application, the processing system running the modeling application will establish collision data. The collision data is a parameter combination having an association relationship with the target primitive; the parameter combination includes the identification ID, position information and primitive type of the target primitive. The processing system can construct the collision data based on the three-simultaneous principle, i.e. the principle of simultaneous generation, simultaneous disappearance and simultaneous update. When constructing the collision data, the collision data can be arranged and stored according to the parameter combination of the preset format. The collision data and the target primitive can be designed according to strict correspondence, i.e. each primitive corresponds to a set of collision data, and the collision data can be stored in the corresponding graph page of the primitive.

[0032] The collision data can be arranged and stored according to the pre-set parameter combination format. For example, the parameter combination format is: int ID_Item, <QList <qpoint>iPontList, QList <qpoint>`nPontList, int typeItem>`. In the above parameter combination format, `ID_Item` represents the identification ID of the target graphic element. A unique ID is automatically generated when the `ID_Item` object is created, serving as the data key. `iPontList` stores the original position data before the object was edited; `nPontList` stores the new position data after the object was edited; `typeItem` stores the type of the graphic element. Collision data can be represented by different graphic element types using `typeItem`: 0 for invalid, 1 for point, 2 for line, 3 for triangle, 4 for rectangle, 5 for rhombus, 6 for circle, and 7 for others.

[0033] S102. Calculate the operating range when editing the model based on the collision data.

[0034] After establishing collision data, the processing system can respond to model editing commands, edit model primitives, and synchronously update the collision data. During model editing, the operation range can be accurately calculated based on the scope. The operation range is the effective model operation range determined by the scope; the scope is determined according to the model editing commands corresponding to the primitive type and position changes.

[0035] like Figure 3 As shown, in some embodiments, when the processing system executes the operation range for calculating model editing based on the collision data, it can receive a model editing instruction and, in response to the instruction, obtain the operation type and the target primitive selected by the instruction. Then, it determines the target scope of the target primitive based on its primitive type. The target scope includes at least one of a page scope, a conditional block scope, and a state machine scope. Based on the target scope, it determines the effective model operation range and updates the collision data according to the data format corresponding to the parameter combination by reading the primitive data within the target scope.

[0036] To accurately calculate the scope of operations when model primitives are edited, the processing system can initiate model editing based on triggering patterns. These triggering patterns include collisions during the regeneration of copied and pasted primitives, collisions upon the initial creation of primitives, and collisions when primitive positions change. The system iterates through various collision scenarios, including collisions between primitives, collisions between primitives and page borders, and collisions between primitives and the borders of bounded primitives.

[0037] Further based on the scope, the effective model operation range is determined, i.e. for the condition block, state machine, basic operator, custom operator, etc. graph element type, the data flow thereof can be the entire graph page, thus these graph elements jointly form the graph page scope which is bounded by the graph page border. For the condition node and the condition node connection line which belong to the condition block internal graph elements, they jointly form the condition block scope which is bounded by the condition block border. For the state, branch, and transition which belong to the state internal graph elements, they jointly form the state machine scope which is bounded by the state machine border. Among them, the editing of the graph elements is only supported to be completed within the same scope, and the system only processes the events of one scope at a time. When the user issues an editing instruction, the system reads the scope in which the last selected graph element is located as the target scope, and automatically invalidates the selection of the objects in the non-target scope.

[0038] According to the determined effective model operation range, the processing system can read the graph element data in the target scope, and arrange and update the collision data according to the custom format. For example, through the model editing instruction, when the position of the target graph element is modified, the processing system can modify the nPontList in the collision data according to the modified position data after obtaining the modified position data, to realize the update of the collision data.

[0039] S103, updating the collision data of the collision graph element according to the operation range.

[0040] After the operation range is calculated, the processing system can calculate and determine the collision data of the collision graph element based on the operation range, and update the collision data of the collision graph element according to the operation range. Among them, the collision graph element is the graph element at the specified stop point position of the model editing instruction, and the graph element has a range overlap with the target graph element.

[0041] For example, when the model editing instruction is to perform a position change operation on the graph element A, the position data after the position change can be determined according to the model editing instruction. Among them, the position data after the change can be represented by a stop point, indicating that the graph element A is moved to the position corresponding to the stop point according to the stop point. Then, after the graph element A is moved to the position corresponding to the stop point, if there is an overlap region between the operation range corresponding to the graph element A and the operation range corresponding to the graph element B, it can be determined that the graph element B is a collision graph element.

[0042] It should be noted that due to the relativity of position movement, the target graph element and the collision graph element have a relative relationship, i.e. for the same model editing instruction, the graph element A is the target graph element, and the graph element B is the collision graph element; while the graph element B is the target graph element, the graph element A is the collision graph element.

[0043] As Figure 4 In some embodiments, when updating the collision data of the collision primitives according to the operation range, the processing system can determine the operation object base point according to the operation type of the model editing instruction. If the operation type is a copy operation, the operation object base point is a center point determined according to the operation range, i.e., the range center method is used to determine the operation object base point of the copy operation.

[0044] For example, the processing system can extract the position data of all selected primitives, calculate the maximum and minimum values of each primitive in the horizontal direction and the vertical direction, and calculate the maximum and minimum values of all primitives in the horizontal direction and the vertical direction. Then, the center point is calculated based on the maximum and minimum values of the entire range in the horizontal direction and the vertical direction, and the obtained point is the base point of the operation object.

[0045] If the operation type is a new operation or a move operation, the operation object base point is the operation point of the model editing instruction. For example, when the user inputs the model editing instruction corresponding to the new operation and the move operation on the target primitive based on the external input device such as a mouse, the processing system can take the mouse press point as the operation object base point.

[0046] After determining the operation object base point, the processing system can determine the operation object docking point by using the straight line distance method. In some embodiments, when determining the operation object docking point by using the straight line distance method, the processing system can first obtain the operation release point of the model editing instruction, and set the docking point of the operation model region according to the operation release point. Then, the movement distance of the operation object is calculated. The movement distance is the coordinate difference between the operation object base point and the docking point of the operation model region. By traversing a plurality of operation objects in the operation range, the difference between the vertex position of the operation object and the movement distance is calculated to obtain a new docking point of the operation object.

[0047] For example, when the mouse release point is the docking point of the operation model region, the distance calculated by subtracting the operation object base point from the docking point of the operation model region can be used as the movement distance of each object. By traversing each operation object, each vertex position is subtracted by the movement distance, and the obtained point is a new set of docking points of each operation object, and the data is recorded.

[0048] After determining the operation object base point and the operation object docking point, the processing system can calculate the position information of the target primitive according to the operation object base point and the operation object docking point, and update the collision data according to the data format corresponding to the parameter combination according to the position information.

[0049] It can be seen that in the process of calculating and determining the collision data of the collision primitives, the processing system can determine the copy operation object base point by using the range center method, and use the operation point as the operation object base point for the new operation and the moving operation. The operation object stop point is determined by using the straight line distance method, and the position data of the operation primitive is calculated, so that the collision data is arranged and updated according to the pre-set parameter combination format, and the automatic arrangement and updating of the collision data is realized, so as to maintain the timeliness of the collision data.

[0050] S104, based on the collision primitive, perform return type primitive automatic collision calculation, and find the optimal position according to the real-time collision data in the primitive automatic collision calculation.

[0051] After determining the collision primitives and updating the collision data, the processing system can also perform automatic collision calculation of return type (spring type) primitives between the target primitives and the collision primitives, that is, perform return type primitive automatic collision calculation based on the collision primitives. The primitive automatic collision calculation includes boundary collision calculation aiming at model display integrity and inter-primitive collision calculation aiming at model display accuracy.

[0052] The return type primitive automatic collision refers to that in the process of moving the target primitives or the collision primitives, once the target primitives and the collision primitives contact, it is considered that collision occurs, at this time, the processing system reversely sets the position, so that the corresponding graphics of the target primitives or the collision primitives can return a certain distance, and the return process is like the reverse rebound of a spring, so it is also called spring type primitive automatic collision.

[0053] In the process of performing the primitive automatic collision, the processing system can read the collision data, perform boundary collision aiming at model display integrity, and / or inter-primitive collision aiming at model display accuracy. Then, the post-collision data is updated to the memory, and the graphics update interface is called.

[0054] As shown in Figure 5 In some embodiments, when performing boundary collision aiming at model display integrity, the processing system can first acquire the constituent elements of the target primitives when performing return type primitive automatic collision calculation based on the collision primitives, the constituent elements including wires, pins and core primitives. Then, boundary collision calculation is performed on the constituent elements respectively to obtain collision results, aiming at the integrity of the graphics. The boundary collision calculation includes pin boundary collision calculation, wire boundary collision calculation and primitive boundary collision calculation.

[0055] Since the elements related to the primitives mainly include three parts of wires, pins and core primitives, and the integrity of the graphics is an important principle of model display, therefore, based on this principle, the collision of the wires, pins and primitives can be performed respectively when performing boundary collision.

[0056] For pin boundary collision calculation, in the model graph, the operator pin is composed of two points of start point and end point; before calculating the collision, the pin data is obtained first, and then it is judged according to the coordinates of the start and end points of the pin whether the pin is a horizontal pin or a vertical pin; finally, it is judged whether the X (Y) axis value of the end point of the horizontal (vertical) pin is less than 0 or greater than the page width (height), if the above conditions are met, it means that the boundary has collided, otherwise it means that the boundary has not collided.

[0057] For line boundary collision calculation, in the model graph, a line can be composed of four points; before calculating the collision, the line data is obtained first, and all the nodes of the line data are sorted and stored in the data structure, and the attribute values of the collision boundary are taken out. For example, X_MIN=left boundary, X_MAX=right boundary, Y_MIN=upper boundary, Y_MAX=lower boundary. Then the corresponding coordinates of the corresponding points after sorting are taken out according to the attribute values, and finally it is judged whether the corresponding coordinate value is less than 0 or greater than the page width (height), if the above conditions are met, it means that the boundary has collided, otherwise it means that the boundary has not collided.

[0058] For primitive boundary collision calculation, before calculating the collision, the primitive data can be obtained first, and all the points of the primitive data are sorted and stored in the data structure, and the attribute values of the collision boundary are taken out. For example, X_MIN=left boundary, X_MAX=right boundary, Y_MIN=upper boundary, Y_MAX=lower boundary. Then the corresponding coordinates of the corresponding points after sorting are taken out according to the attribute values, and finally it is judged whether the corresponding coordinate value is less than 0 or greater than the page width (height), if the above conditions are met, it means that the boundary has collided, otherwise it means that the boundary has not collided.

[0059] After obtaining the collision result, the collision result can be read to determine whether the constituent element of the target primitive collides with the boundary. If the collision result represents that the constituent element collides with the boundary, the collision data is updated according to the collision result to obtain the real-time collision data. If the collision result represents that the constituent element does not collide with the boundary, the model editing operation corresponding to the model editing instruction is executed.

[0060] In the process of performing the return type primitive automatic collision calculation, the processing system can update the collision data in real time according to the calculation data generated in the collision process to obtain real-time collision data. The real-time collision data includes collision points and collision directions. Based on the real-time collision data, the processing system can find the optimal position, that is, after each collision calculation, the optimal position is found.

[0061] To find the optimal location, in some embodiments, when the processing system performs a return-based automatic collision calculation based on the colliding primitives, and searches for the optimal location based on real-time collision data from the automatic collision calculation, it can select a reference point within the corresponding operating range of the target primitive and the colliding primitives. By comparing the coordinates of the reference points of the target primitive and the colliding primitives, the collision point is determined, and then the collision edge is determined according to the collision point. The collision point is a reference point within the operating range of the colliding primitive in the target primitive.

[0062] For example, such as Figure 6 As shown, for the collision calculation between primitives aimed at improving model display accuracy, the processing system uses the lower left corner of the border as the base point of the coordinate system. When the primitives in this model are rectangular primitives, collisions between points and lines are not considered. Therefore, the target primitive (operational primitive) can be selected as impact primitive A, and the collision primitive can be selected as primitive B. Then, iteratively, it can be determined whether each point (impact point) of A is inside primitive B. The criteria for determination are: the x-axis coordinate of the impact point is greater than the x-axis coordinate of the left side of the B rectangle; the x-axis coordinate of the impact point is less than the x-axis coordinate of the right side of the B rectangle; the y-axis coordinate of the impact point is greater than the y-axis coordinate of the top of the B rectangle; and the y-axis coordinate of the impact point is less than the y-axis coordinate of the bottom of the B rectangle.

[0063] After the above judgment, the processing system also needs to swap primitive A and primitive B, and repeat the judgment according to the above-mentioned collision calculation method between primitives with the goal of model display accuracy, so as to obtain the collision point and the collision edge of the collided primitive.

[0064] After determining the collision edge, the processing system can perform a return-type automatic collision calculation based on the collision edge. In some embodiments, when the processing system performs a return-type automatic collision calculation based on the collision element and searches for the optimal position based on the real-time collision data in the automatic collision calculation, it can obtain the collision point of the target element and the collision direction corresponding to the collision point.

[0065] After acquiring the collision point of the target primitive and the corresponding collision direction, the processing system can also determine whether the current collision direction is the first collision. This involves acquiring the collision history data of the target primitive and extracting the collision records along the collision direction from the historical data to determine the collision order. If the collision order is the first collision, the processing system can record the direction axis corresponding to the collision direction and then move the collision point backward along the direction axis by a preset number of pixels to obtain the collision return point.

[0066] For example, in order to find the optimal position after collision, the processing system can obtain the point of collision and the direction of the point of collision after the collision occurs, and determine whether it is the first collision on the coordinate axis of the direction. If it is the first collision, the direction axis corresponding to the current collision direction can be recorded, and the collision point is moved 5 pixels in the reverse direction along the direction as the collision return base point.

[0067] Then, the return distance is moved in the reverse direction along the direction axis based on the collision return base point to obtain a new parking point. The return distance is 1 / 2 of the size of the target primitive operation range in the direction axis. Then, the return type primitive automatic collision calculation is re-executed according to the new parking point, and the optimal position is found according to the real-time collision data after the re-executed return type primitive automatic collision calculation. That is, the new parking point of the graphic region is obtained by moving the original width or height by half in the reverse direction based on the current base point, and the collision calculation is continued according to the new parking point until there is no overlapping region between the target primitive and the collision primitive.

[0068] If the collision order is not the first collision, the same direction twice finding closed loop algorithm can be used to find the optimal position. In some embodiments, when the processing system uses the same direction twice finding closed loop algorithm to find the optimal position, the position type data can be defined according to the collision direction, and the record data of the last collision can be obtained. The record data includes a record direction, which is used to represent the collision direction of the last collision. By comparing the collision direction and the record direction, if the collision direction is consistent with the record direction, the target primitive is restored to the original position according to the position information.

[0069] For example, for the non-first collision on the coordinate axis corresponding to the current collision direction, the processing system can use the same direction twice finding closed loop algorithm to prove that there is no optimal position at the current editing point, that is, after the second collision in the same direction, the position found by reverse search will return to the position of the first collision, which proves that there is no reasonable parking position at the current parking point. Therefore, the data that stores the direction of the collision can be defined as positionType, which records the data of the last collision, and the default is 0. The horizontal direction is represented by 1, and the vertical direction is represented by 2. When the collision occurs, the last positionType is obtained, and it is determined whether it is consistent with the current direction. If it is consistent, the collision is ended, which proves that there is no optimal position in the current editing operation process. At this time, the position data before the graphic editing can be restored, that is, restored to the original position.

[0070] If the collision direction is inconsistent with the recording direction, the optimal position is continued to be searched by initializing the recording data. That is, when the directions are inconsistent, the first collision in the direction is represented, and the positionType can be initialized to continue searching the position, as shown in the following formulas. Figure 7 、 Figure 8 、 Figure 9

[0071] S105, performing graphic update on the target graphics element according to the optimal position.

[0072] After the optimal position is obtained by real-time collision data calculation, the processing system can perform graphic update on the target graphics element according to the optimal position, so as to realize the update of the graphics after the collision. When performing the graphic update, the processing system can synchronize the graphic update with the model editing and the collision detection. In addition, the graphic update is divided into event execution process update and event end update.

[0073] For the update in the event execution process, the processing system can perform the event execution process update mainly in the moving operation. When the mouse is moved, the collision calculation is not performed. The point of the mouse movement is taken as the docking point, and the new position data of all operation objects is calculated. In addition, the position frame of the operation object is drawn in the form of a dashed line in real time. The graphic of the event execution process update is only used for the user to view the effect, and is not the final graphic. In addition, the graphics of the event execution process exist in the scenes that are not allowed to exist in the model graphics, such as overlapping and intersecting.

[0074] For the update at the end of the event, the processing system can perform the update at the end of the event in all operations. The graphic of the update at the end of the event is the final graphic, and does not exist in the scenes such as overlapping and intersecting. At the end of the event, the end point of the mouse is taken as the center point of the region, and the collision calculation interface is called. The post-collision data of the graphics element is read, and it is judged whether there is a collision. If there is no collision, the new position data is read, and the graphic is drawn. If there is a collision, the original data of the graphics element is read, the graphic is drawn, and the model graphics and the related information display are updated.
