Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of industrial software, and in particular, to a Modelica model compilation method, apparatus, device, and storage medium. Background Art

[0002] Mechanisms such as Modification and redeclare in the Modelica language enable different models and variants to be derived from the same model, facilitating model reuse. However, these reuse mechanisms pose challenges to model compilation.

[0003] At the language level, a Modelica model is a type, a special type that does not require instance declaration, and an instance of a type is a component. In the physical world, a type is a collection of entities with the same characteristics. For example, resistors in electricity are a type, a collection of various resistor components, and a component is an instance of a type, corresponding to parts or individuals in the physical world.

[0004] Model reuse is to declare instances of a type and apply modifications or redeclarations to change the parameters, characteristics of the type, or replace components in the type. These reused instances have both exactly the same content and different content. Compiling according to the semantics in the Modelica specification requires processing these instances one by one. However, since Modelica reusable models often contain a large number of instances of the same type, compilation efficiency becomes a key issue. Especially in reusable models of large and complex systems, processing these instances one by one is a time-consuming process, which not only affects the model development efficiency but also increases the consumption of computing resources due to the too long compilation time. Summary of the Invention

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0027] Figure 1 It is a flowchart of a Modelica model compilation method provided by an embodiment of the present invention. The embodiment of the present invention is applicable to the scenario of compiling a Modelica model. This method can be executed by a Modelica model compilation device, and the device can be implemented in software and / or hardware manners.

[0028] As Figure 1 shown, the Modelica model compilation method includes the following steps:

[0029] S110. Determine the target model type of the target Modelica model.

[0030] Among them, the target Modelica model may be a Modelica model that needs to be compiled. The result of Modelica model compilation is a DAE (Differential Algebraic Equation, differential algebraic equation) in a mathematical sense, including variables and equations. The variables of the DAE are the atomic components in the Modelica model. The so-called atomic components refer to those with only a single attribute in their types and cannot be further split, and such a type is the atomic type. The equations of the DAE come from the equations described in three ways in the Modelica model. One is the ordinary equation in the equation area, expressed according to the mathematical form of the equation. The second is the connection equation, generated through the connection statements in the equation area. The third is the declaration equation, defined when the component is declared, and the form is that the variable is always equal to a value. Among them, the ordinary equation and the connection equation cannot be changed during the model reuse process, while the declaration equation can replace the value after the equal sign through the variant mechanism during reuse, deriving new components with different characteristics. The "equations and connections" described in the embodiments of the present invention below include ordinary equations, connection equations and declaration equations.

[0031] Exemplarily Figure 2 It is a structural schematic diagram of a Modelica model provided by an embodiment of the present invention. The "type" in the first column of boxes represents the Modelica model. As Figure 2As shown, a Modelica model can include multiple levels. At the first level, the Modelica model can include multiple components (Component 1 to Component n), as well as equations and connections associated with the components at this level. Further, the components at the first level can also have corresponding subordinate levels. For example, Component 1 can include multiple sub-components (Component 1-1 to Component 1-m), as well as equations and connections associated with the sub-components at this level; the components at the second level can also have corresponding subordinate levels. For example, Component 1-m can include multiple sub-components (Component 1-1-1 to Component 1-m-k), as well as equations and connections associated with the sub-components at this level; and so on until the component is an atomic component. Among them, the set composed of multiple components, equations and connections at the same level can be collectively referred to as a "type". In addition, it should be noted that the "equations and connections associated with the components" in the following includes the equations and connections associated with the components at each level. For example, in the case where Component 1-m is an atomic component, the equations and connections associated with Component 1 include: the equations and connections associated with Component 1 at the first level, the equations and connections associated with Component 1 at the second level, and the equations and connections associated with Component 1 at the third level.

[0032] Further, the target model type can be a type indicating whether the target Modelica model can be differentially compiled. Among them, the target model type includes: replaceable model or non-replaceable model. In the case where the target model type is a replaceable model, the content in the target Modelica model cannot be differentially compiled; in the case where the target model type is a non-replaceable model, the content in the target Modelica model can be differentially compiled. Specifically, semantic analysis can be performed on the target Modelica model, and based on whether the target Modelica model contains a preset keyword, the target model type of the target Modelica model can be determined.

[0033] Exemplarily, the model prefix name of the target Modelica model can be obtained. In the case where the model prefix name does not contain a preset replaceable identifier, it is determined that the target model type is a non-replaceable model; in the case where the model prefix name contains a preset replaceable identifier, it is determined that the target model type is a replaceable model. Among them, the model prefix name can be the file name of the file to which the target Modelica model belongs. The preset replaceable identifier can be set manually. For example, the preset replaceable identifier can be set to "replaceable". If the model prefix name of the target Modelica model contains "replaceable", then the target model type is a replaceable model, otherwise it is a non-replaceable model.

[0034] S120. When the target Modelica model is an irreplaceable model, for each component in the target Modelica model, determine the target component type of the component.

[0035] Among them, the component can be a component included in the target Modelica model. Specifically, the component can include components at each level in the target Modelica model. For example, in Figure 2 , each of the components from component 1 to component n, components 1-1 to 1-m, and components 1-1-1 to 1-m-k can be used as a component. The target component type can be a type indicating whether the component can be differentially compiled.

[0036] Among them, the target component type can include: fixed component, candidate component, or template component. For a component marked as a fixed component, the component and the associated fixed equations can be directly copied and connected to the result. If there is any variation of the fixed component in any part of the component environment information where the component is located, take the top-level equation variation. If the component has a replaceable declaration equation, use the equation variation to replace it and add it to the result set. Otherwise, add the top-level equation variation to the result set.

[0037] For a component marked as a template component, if the component is not redeclared using the redeclare keyword in the component environment information where the component is located, directly copy the component and the associated template components, equations, and connections to the result set. Otherwise, use the redeclared component to replace the template components and the template components included in the template equations and connections, and add the equations and connections to the result set.

[0038] For a component marked as a candidate component, calculate the value of its condition in the component environment information where the component is located. If it is false, the component and the associated candidate connections are directly ignored. Otherwise, copy the candidate component to the result set and copy the associated candidate connections to the result set.

[0039] Among them, the component environment information includes the set of the component's associated components at the current layer and upper layers. For example, in the layer containing the component and the upper layers declared at that layer, up to the layer of the upper component, and so on up to the top-level model in sequence, all the ordered layers and component sets above this component level are called the component environment information corresponding to this component.

[0040] Furthermore, when determining the target component type of a component, the component prefix name of the component can be obtained. When the component prefix name contains a preset replaceable identifier, determine the target component type of the component as a template component; when the component contains a conditional statement, determine the target component type of the component as a candidate component; otherwise, determine the target component type of the component as a fixed component.

[0041] Among them, the component prefix name can be the file name of the file to which the component belongs. The preset replaceable identifier here can be the same as the preset replaceable identifier in step S110. For example, the preset replaceable identifier can be set to "replaceable". If the component prefix name of the component contains "replaceable", then the target component type of the component is a template component. Further, the code corresponding to the component can be judged. If the code contains conditional statements, it is determined that the target component type of the component is a candidate component; otherwise, it is determined that the target component type of the component is a fixed component.

[0042] Optionally, in order to reduce the computational complexity of determining the target component type of the component, the determination order of different component types can be set in ascending order of the determination computational complexity. For example, it can first be determined whether the component is of the template type. If the component is not of the template type, then it is determined whether the component is of the candidate type. If the component is not of the candidate type, then it is determined whether the component is of the fixed type.

[0043] S130. Based on the target component type of the component, perform a corresponding component compilation operation on the component.

[0044] Among them, for components of different target component types, a component compilation operation corresponding to the target component type can be performed, thereby realizing the compilation process of the target Modelica model.

[0045] The technical solution provided by the embodiments of the present invention determines the target model type of the target Modelica model; among them, the target model type includes: replaceable model or non-replaceable model; in the case where the target Modelica model is a non-replaceable model, for each component in the target Modelica model, determine the target component type of the component; among them, the target component type includes: fixed component, candidate component or template component; based on the target component type of the component, perform a corresponding component compilation operation on the component. The technical solution of the embodiments of the present invention solves the problem in the prior art that when compiling a Modelica model, each instance is compiled based on a single standard semantics, resulting in insufficient compilation efficiency. It can perform corresponding compilation operations based on the component types of the components in the Modelica model, improving the compilation efficiency of the Modelica model.

[0046] Figure 3It is another flowchart of the Modelica model compilation method provided by the embodiments of the present invention. The embodiments of the present invention can be applied to the scenario of compiling Modelica models. Based on the above embodiments, this embodiment further illustrates how to determine the target model type of the target Modelica model; and how to perform corresponding component compilation operations on components based on the target component types of the components. The device can be implemented in software and / or hardware and integrated into a computer device with application development functions.

[0047] As Figure 3 shown, the Modelica model compilation method includes the following steps:

[0048] S210. Determine the target model type of the target Modelica model.

[0049] S220. In the case where the target Modelica model is an irreplaceable model, for each component in the target Modelica model, determine the target component type of the component.

[0050] S230. Obtain the component environment information corresponding to the component.

[0051] S240. According to the component environment information and the target component type of the component, perform corresponding component compilation operations on the component.

[0052] Among them, for components with different target component types, different component compilation operations can be performed on the components according to the component environment information.

[0053] Exemplarily, in the case where the target component type of the component is a fixed component, performing corresponding component compilation operations on the component according to the component environment information and the target component type includes: in the case where there is a new variant in the component environment information, replacing the original equation of the component based on the equation in the new variant; in the case where there is no new variant in the component environment information and the component has replaceable equations, replacing the original equation of the component based on the replaceable equations.

[0054] Among them, determining whether there is a new variant in the component environment information can be determined by whether there are new changes in the equation data in the equation component environment information. For example, if the original equation of the component records "a = 5" and the equation in the component environment information records "a = 6", it is determined that there is a new variant. Further, in the case where there is a new variant in the component environment information, the original equation of the component can be replaced based on the equation in the component environment information. Optionally, for components with a target component type of fixed components, only the declared equations corresponding to the components can be subjected to the above new variant determination, and for the fixed equations and connection equations corresponding to the components, direct copy operations can be performed.

[0055] Exemplarily, Figure 4 is a compilation operation flowchart for a fixed component provided by an embodiment of the present invention. As Figure 4 shown, the compilation operation process of the fixed component includes the following steps: Step 1, copy the component to the result set; Step 2, copy the equations marked as fixed equations and the connections marked as fixed connections associated with the component to the result set; Step 3, search the environment where the component is located. If there is a variant, add the declared equation of the new variant to the result set, otherwise copy the original declared equation to the result set.

[0056] In the case where the target component type of the component is a template component, according to the component environment information and the target component type of the component, perform corresponding component compilation operations on the component, including: when there is a preset declaration identifier in the component environment information, replace the component based on the component declared in the component environment information, and modify the equations and connections associated with the component; when there is no preset declaration identifier in the component environment information, copy the template component. Among them, the preset declaration identifier can be an identifier indicating whether to perform redeclaration. Among them, during the compilation process of the model, the user can perform editing operations on the data of the Modelica model, and the edited data can be marked with the corresponding preset declaration identifier. Exemplarily, "redeclare" can be selected as the preset declaration identifier.

[0057] Exemplarily, Figure 5 is a compilation operation flowchart for a template component provided by an embodiment of the present invention. As Figure 5 shown, the compilation operation process of the template component includes the following steps: Step 1, search the environment where the component is located. If there is "redeclare", replace the template component with the redeclared component and add it to the result set, and go to Step 2, otherwise, go to Step 3; Step 2, replace the template components marked as template equations and template connections associated with the template component with the redeclared components; Step 3, directly copy the template component to the result set, and keep the equations and connections of the template component unchanged and copy them to the result set.

[0058] In the case where the target component type of the component is a candidate component, according to the component environment information and the target component type of the component, perform corresponding component compilation operations on the component, including: when the condition in the component environment information is true, copy the candidate component and the equations and connections associated with the candidate component; when the condition in the component environment information is not true, delete the candidate component and the equations and connections associated with the candidate component. Among them, the condition being true means satisfying the conditional statement.

[0059] Exemplarily, Figure 6 is a compilation operation flowchart for a candidate component provided by an embodiment of the present invention. AsFigure 6 As shown in the figure, the compilation operation process of the candidate components includes the following steps: Step 1, search the environment where the candidate components are located. If the conditions of the candidate components are true, copy the candidate components, candidate equations, and candidate connections into the result set; otherwise, go to Step 2. Step 2, ignore the candidate components, candidate equations, and candidate connections.

[0060] Optionally, it is also possible to determine whether there is a redeclaration of the type, and then perform the compilation operation according to the determination result. Exemplarily, Figure 7 is a flowchart of the compilation operation for types provided by an embodiment of the present invention. As Figure 7 shown, the compilation operation process of the type includes the following steps: Search the environment where the type is located. If there is a "redeclare", compile the redeclared type, and add the components, equations, and connections therein to the result set; otherwise, go to Step 2. Step 2, compile the replaceable type, and add the components, equations, and connections therein to the result set.

[0061] Optionally, during the compilation of the model, the compilation tasks of components at the same level can all be executed in parallel as a separate task, but the compilation tasks of components at different levels can only be executed serially in the top-down order.

[0062] Exemplarily, to better understand the technical solution provided by the present invention, specific embodiments are introduced below. Figure 8 is a flowchart of the work for compiling a Modelica model provided by an embodiment of the present invention. As Figure 8 shown, the work process for compiling a Modelica model includes the following steps:

[0063] (1) Select the target Modelica model as the current type.

[0064] (2) Parse the prefix of the current type. If there is a replaceable, mark the model type as a replaceable type and go to (11).

[0065] (3) Select the next component in the current type, parse the prefix of the component. If there is a replaceable, mark the component as a template component, and mark the equations and connections associated with the component as template equations and template connections respectively, and go to (7).

[0066] (4) Parse the conditions of the component. If there are conditions, mark the component as a candidate component, and mark the equations and connections associated with the component as candidate equations and candidate connections respectively, and go to (7).

[0067] (5) Parse the variants of the component. If there are variants, mark the declared equations of the variants as replaceable declared equations.

[0068] (6) The component is marked as a fixed component, and the associated equation and connection are marked as a fixed equation and a fixed connection respectively.

[0069] (7) If there are fixed marks in the marks of the equations and connections associated with the component and there are template or candidate marks at the same time, remove the fixed marks.

[0070] (8) The component, equation, and connection are converted into an internal data representation, and the connection generates a local connection diagram.

[0071] (9) Obtain the type of the component. If the type is not an atomic type, set the component type to the current type and go to (2).

[0072] (10) If there are still components of the current type, go to (3).

[0073] (11) The type processing is completed.

[0074] The technical solution provided by the embodiment of the present invention determines the target model type of the target Modelica model; in the case where the target Modelica model is an irreplaceable model, for each component in the target Modelica model, determines the target component type of the component; obtains the component environment information corresponding to the component; and performs corresponding component compilation operations on the component according to the component environment information and the target component type of the component. The technical solution of the embodiment of the present invention solves the problem in the prior art that when compiling a Modelica model, each instance is compiled based on a single specification semantics, resulting in insufficient compilation efficiency, and can perform corresponding compilation operations based on the component types of the components in the Modelica model, improving the compilation efficiency of the Modelica model.

[0075] Figure 9 It is a schematic structural diagram of a Modelica model compilation device provided by an embodiment of the present invention. The embodiment of the present invention is applicable to the scenario of compiling a Modelica model. The device can be implemented in a software and / or hardware manner and integrated in a computer device with application development functions.

[0076] As Figure 9 shown, the Modelica model compilation device includes: a model type determination module 310, a component type determination module 320, and a component compilation module 330.

[0078] The technical solution provided by the embodiments of the present invention determines the target model type of the target Modelica model; among them, the target model type includes: replaceable model or non-replaceable model; when the target Modelica model is a non-replaceable model, for each component in the target Modelica model, determine the target component type of the component; among them, the target component type includes: fixed component, candidate component or template component; based on the target component types of the components, perform corresponding component compilation operations on the components. The technical solution of the embodiments of the present invention solves the problem in the prior art that when compiling a Modelica model, each instance is compiled based on a single specification semantics, resulting in insufficient compilation efficiency, and can perform corresponding compilation operations based on the component types of the components in the Modelica model, improving the compilation efficiency of the Modelica model.

[0084] In an alternative embodiment, the component compilation module 330 includes: a candidate component compilation unit, configured to: copy the candidate component and the equations and connections associated with the candidate component when the condition in the component environment information is true; and delete the candidate component and the equations and connections associated with the candidate component when the condition in the component environment information is not true.

[0086] Figure 10 It is a schematic structural diagram of a computer device provided by an embodiment of the present invention. Figure 10 The block diagram of an exemplary computer device 12 suitable for implementing the embodiments of the present invention is shown. Figure 10 The shown computer device 12 is only an example, and should not bring any limitation to the functions and usage scope of the embodiments of the present invention. The computer device 12 can be any terminal device with computing capabilities and can be configured in the Modelica model compilation device.

The components of the computer device 12 may include, but are not limited to: one or more processors or processing units 16, a system memory 28, and a bus 18 that connects different system components (including the system memory 28 and the processing unit 16).

[0088] The bus 18 can be one or more of several types of bus structures, including a memory bus or memory controller, a peripheral bus, a graphics acceleration port, a processor, or a local bus using any of the various bus structures.
