Description

Technical Field

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

[0002] The modification and redeclare mechanisms of the Modelica language make it possible to derive different models and variants from the same model, thus facilitating model reuse. However, these reuse mechanisms bring challenges to model compilation.

[0003] From the language level, Modelica models are types, which are special types that do not need to declare instances. Instances of types are components. From the physical world, types are collections of entities with the same characteristics. For example, a resistor in electricity is a type, which is a collection of various resistor parts, and components are instances of types, corresponding to parts or individuals in the physical world.

[0004] Model reuse is declaring instances of a type and applying variants or re-declarations to change parameters, properties, or components of the type. These reused instances may have identical or different contents. 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 results in long compilation times that not only affect model development efficiency, but also increase the consumption of computing resources. Summary of the invention

[0005] The embodiments of the present invention provide a Modelica model compilation method, apparatus, device and storage medium. The technical solution of the embodiments of the present invention solves the problem of insufficient compilation efficiency caused by compiling each instance based on a single specification semantics when compiling the Modelica model in the prior art. The corresponding compilation operation can be performed based on the component type of the component in the Modelica model, thereby improving the compilation efficiency of the Modelica model.

DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] Figure 1 It is a flow chart of a Modelica model compilation method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of compiling a Modelica model. The method can be executed by a Modelica model compilation device, and the device can be implemented by software and / or hardware.

[0014] like Figure 1 As shown, the Modelica model compilation method includes the following steps: S110 , determining the target model type of the target Modelica model.

[0015] Among them, the target Modelica model can be a Modelica model that needs to be compiled. The result of Modelica model compilation is DAE (Differential Algebraic Equation) in the mathematical sense, including variables and equations. The variables of DAE are atomic components in the Modelica model. The so-called atomic component means that its type has only a single attribute and cannot be further divided. This type is the atomic type. The equations of DAE come from equations described in three ways in the Modelica model. The first is the ordinary equation in the equation area, which is expressed in the mathematical form of the equation. The second is the connection equation, which is generated by the connection statement in the equation area. The third is the declaration equation, which is 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, and the declaration equation can replace the value after the equal sign through the deformation mechanism when reused, and derive new components with different characteristics. The "equations and connections" described below in the embodiment of the present invention include ordinary equations, connection equations and declaration equations.

[0016] For example, Figure 2 is a schematic diagram of the structure of a Modelica model provided by an embodiment of the present invention. The “type” in the first column box represents a Modelica model. Figure 2As shown, the Modelica model can include multiple levels. In 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 in this level. Furthermore, the components in the first level can also have corresponding subordinate levels. For example, component 1 can include multiple subcomponents (component 1-1 to component 1-m), as well as equations and connections associated with the subcomponents in this level; the components in the second level can also have corresponding subordinate levels. For example, component 1-m can include multiple subcomponents (component 1-1-1 to component 1-mk), as well as equations and connections associated with the subcomponents in this level; and so on, until the component is an atomic component. Among them, the set consisting of multiple components, equations and connections in the same level can be collectively referred to as "type". In addition, it should be pointed out that the "equations and connections associated with components" mentioned below include equations and connections associated with components in each level. For example, when component 1-m is an atomic component, the equations and connections associated with component 1 include: equations and connections associated with component 1 in the first level, equations and connections associated with component 1 in the second level, and equations and connections associated with component 1 in the third level.

[0017] Furthermore, the target model type may be a type indicating whether the target Modelica model can be differentially compiled. The target model type includes: a replaceable model or a non-replaceable model. When the target model type is a replaceable model, the content in the target Modelica model cannot be differentially compiled; when the target model type is a non-replaceable model, the content in the target Modelica model can be differentially compiled. Specifically, the target Modelica model may be semantically analyzed, and the target model type of the target Modelica model may be determined based on whether the target Modelica model contains preset keywords.

[0018] Exemplarily, the model prefix name of the target Modelica model can be obtained. When the model prefix name does not contain a preset replaceable identifier, the target model type is determined to be a non-replaceable model; when the model prefix name contains a preset replaceable identifier, the target model type is determined to be a replaceable model. 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", the target model type is a replaceable model, otherwise it is a non-replaceable model.

[0019] S120 . When the target Modelica model is a non-replaceable model, determine a target component type of each component in the target Modelica model.

[0020] The components may be components included in the target Modelica model. Specifically, the components may include components in each level of the target Modelica model. For example, Figure 2 In the example, each of components 1 to component n, components 1-1 to component 1-m, and components 1-1-1 to component 1-mk may be a component. The target component type may be a type indicating whether the component can be differentially compiled.

[0021] The target component type may include: fixed component, candidate component or template component. For a component marked as a fixed component, the component and the associated fixed equation can be directly copied and connected to the result. If there is a variant of the fixed component anywhere in the component environment information where the component is located, the top-level equation variant is taken. If the component has a replaceable declared equation, the equation variant is used to replace it and added to the result set. Otherwise, the top-level equation variant is added to the result set.

[0022] 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, the component and the associated template components, equations, and connections are directly copied to the result set. Otherwise, the template components and the template components contained in the template equations and connections are replaced with the redeclared component, and the equations and connections are added to the result set.

[0023] For components marked as candidate components, calculate the value of their conditions in the component environment information where the component is located. If it is false, the component and the associated candidate connection are directly ignored. Otherwise, copy the candidate component to the result set, and the associated candidate connection is copied to the result set.

[0024] The component environment information includes the set of components in the current layer and upper layer components associated with the component. For example, in the layer containing the component and the upper layer components declared in the layer, to the layer of the upper layer components, and so on, all ordered layers and component sets above the component layer are called the component environment information corresponding to the component.

[0025] 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, the target component type of the component is determined to be a template component; when the component contains a conditional statement, the target component type of the component is determined to be a candidate component; when the component contains an equation variation, the target component type of the component is determined to be a replaceable component.

[0026] 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 consistent with 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", the target component type is a replaceable component, otherwise it is a non-replaceable component. Furthermore, the code corresponding to the component can be judged. If the code contains conditional statements, the target component type of the component is determined to be a candidate component; if the code contains equation variations, the target component type of the component is determined to be a replaceable component.

[0027] Optionally, in order to reduce the amount of calculation for determining the target component type of a component, the determination order of different component types may be set in the order of the determination calculation amount from small to large. For example, it may be determined whether the component is a template type first, and if the component is not a template type, it may be determined whether the component is a candidate type, and if the component is not a candidate type, it may be determined whether the component is a fixed type.

[0028] S130. Based on the target component type of the component, perform a corresponding component compilation operation on the component.

[0029] Among them, for components of different target component types, component compilation operations corresponding to the target component types can be executed, thereby realizing the compilation process of the target Modelica model.

[0030] The technical solution provided by the embodiment of the present invention determines the target model type of the target Modelica model; wherein the target model type includes: a replaceable model or a non-replaceable model; when the target Modelica model is a non-replaceable model, for each component in the target Modelica model, determines the target component type of the component; wherein the target component type includes: a fixed component, a candidate component or a template component; based on the target component type of the component, performs a corresponding component compilation operation on the component. The technical solution of the embodiment of the present invention solves the problem that the prior art compiles each instance separately based on a single specification semantics when compiling the Modelica model, resulting in insufficient compilation efficiency. The corresponding compilation operation can be performed based on the component type of the component in the Modelica model, thereby improving the compilation efficiency of the Modelica model.

[0031] Figure 3It is another flow chart of a Modelica model compilation method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of compiling a Modelica model. Based on the above embodiment, 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 the component based on the target component type of the component. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0032] like Figure 3 As shown, the Modelica model compilation method includes the following steps: S210 , determining the target model type of the target Modelica model.

[0033] S220 : When the target Modelica model is a non-replaceable model, determine a target component type of each component in the target Modelica model.

[0034] S230: Obtain component environment information corresponding to the component.

[0035] S240: Perform a corresponding component compilation operation on the component according to the component environment information and the target component type of the component.

[0036] Among them, for components of different target component types, different component compilation operations can be performed on the components according to the component environment information.

[0037] Exemplarily, when the target component type of the component is a fixed component, corresponding component compilation operations are performed on the component according to the component environment information and the target component type, including: when 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; when there is no new variant in the component environment information and the component has a replaceable equation, replacing the original equation of the component based on the replaceable equation.

[0038] Among them, to determine whether there is a new variation in the component environment information, it can be determined by whether there is a new change in the equation data in the equation component environment information. For example, if "a=5" is recorded in the original equation of the component, and "a=6" is recorded in the equation in the component environment information, it is determined that there is a new variation. Furthermore, in the case where there is a new variation 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 whose target component type is a fixed component, the above-mentioned new variation determination can be performed only on the declared equation corresponding to the component, and the fixed equation and connection equation corresponding to the component can be directly copied.

[0039] For example, Figure 4 1 is a flow chart of a compilation operation for a fixed component provided by an embodiment of the present invention. Figure 4 As 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, and if there is a variant, use the new variant declaration equation to add it to the result set, otherwise copy the original declaration equation to the result set.

[0040] When the target component type of the component is a template component, the corresponding component compilation operation is performed on the component according to the component environment information and the target component type of the component, including: when there is a preset declaration identifier in the component environment information, the component is replaced based on the component declared in the component environment information, and the equations and connections associated with the component are modified; when there is no preset declaration identifier in the component environment information, the template component is copied. The preset declaration identifier can be an identifier indicating whether to redeclare. During the compilation of the model, the user can edit 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.

[0041] For example, Figure 5 1 is a flow chart of a compiling operation for a template component provided by an embodiment of the present invention. Figure 5 As 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 re-declared component and add it to the result set, and go to step 2, otherwise, go to step 3; Step 2, the template component associated with the template component is marked as template equations and template connections. Replace it with the re-declared component; Step 3, directly copy the template component to the result set, and the equations and connections of the template component remain unchanged and are copied to the result set.

[0042] When the target component type of the component is a candidate component, a corresponding component compilation operation is performed on the component according to the component environment information and the target component type of the component, including: when the condition in the component environment information is true, copying the candidate component and equations and connections associated with the candidate component; when the condition in the component environment information is not true, deleting the candidate component and equations and connections associated with the candidate component. Wherein, the condition being true means that the conditional statement is satisfied.

[0043] For example, Figure 6 is a flow chart of a compilation operation for a candidate component provided by an embodiment of the present invention. Figure 6As shown, the compilation operation process of the candidate component includes the following steps: Step 1, search the environment where the candidate component is located. If the condition of the candidate component is true, copy the candidate component, candidate equation and candidate connection to the result set, otherwise, go to step 2; Step 2, ignore the candidate component, candidate equation and candidate connection.

[0044] Optionally, it is also possible to determine whether the type is redeclared, and then perform a compilation operation based on the determination result. For example, Figure 7 This is a flow chart of a type-specific compilation operation provided by an embodiment of the present invention. Figure 7 As shown, the compilation operation process of the type includes the following steps: search the environment where the type is located, if there is "redeclare", compile the redeclared type, and add the components, equations and connections therein to the result set, otherwise, go to step two; step two, compile the replaceable type, and add the components, equations and connections therein to the result set.

[0045] Optionally, during the compilation of the model, the compilation tasks of components at the same level can be executed in parallel as a single task, but the compilation tasks of components at different levels can only be executed serially from top to bottom.

[0046] For illustrative purposes, in order to better understand the technical solution provided by the present invention, specific embodiments are introduced below. Figure 8 This is a workflow diagram for compiling a Modelica model provided by an embodiment of the present invention. Figure 8 As shown in the figure, the workflow for compiling a Modelica model includes the following steps: (1) Select the target Modelica model as the current type.

[0047] (2) Parse the prefix of the current type. If replaceable is found, mark the model type as a replaceable type and go to (11).

[0048] (3) Select the next component in the current type, parse the prefix of the component, and if it is replaceable, mark the component as a template component. Mark the equations and connections associated with the component as template equations and template connections respectively and transfer to (7).

[0049] (4) Analyze the conditions of the component. If the conditions are met, mark the component as a candidate component. Mark the equations and connections associated with the component as candidate equations and candidate connections respectively and proceed to (7).

[0050] (5) Analyze the variants of the component. If there are any variants, mark the declaration equation of the variant as an interchangeable declaration equation.

[0051] (6) The components are marked as fixed components, and the associated equations and connections are marked as fixed equations and fixed connections, respectively.

[0052] (7) If there is a fixed tag in the equation or connected tag associated with the component and there is also a template or candidate tag, remove the fixed tag.

[0053] (8) Components, equations and connections are converted into internal data representations, and connections are generated to generate local connection graphs.

[0054] (9) Get 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).

[0055] (10) If the current type still has components, go to (3).

[0056] (11) Type processing ends.

[0057] The technical solution provided by the embodiment of the present invention determines the target model type of the target Modelica model; when the target Modelica model is a non-replaceable 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 that the prior art compiles each instance separately based on a single specification semantics when compiling the Modelica model, resulting in insufficient compilation efficiency. The corresponding compilation operations can be performed based on the component type of the component in the Modelica model, thereby improving the compilation efficiency of the Modelica model.

[0061] The technical solution provided by the embodiment of the present invention determines the target model type of the target Modelica model; wherein the target model type includes: a replaceable model or a non-replaceable model; when the target Modelica model is a non-replaceable model, for each component in the target Modelica model, determines the target component type of the component; wherein the target component type includes: a fixed component, a candidate component or a template component; based on the target component type of the component, performs a corresponding component compilation operation on the component. The technical solution of the embodiment of the present invention solves the problem that the prior art compiles each instance based on a single specification semantics when compiling the Modelica model, resulting in insufficient compilation efficiency.
