[0002] With the development of the process industry, simulation software is increasingly widely used in industries such as chemical engineering, petroleum, and pharmaceuticals. Most traditional simulation software adopts the C / S (Client / Server) architecture. Although this architecture can better meet local computing requirements, there are many limitations in networked applications and cross-platform support. With the development of information technology, simulation software based on B / S (Browser / Server) architecture has gradually attracted attention. It uses a web browser as the user interface and does not require client installation, greatly simplifying the complexity of deployment and maintenance.

[0027] According to an embodiment of the design method of the industrial process simulation software based on the B / S architecture of the present invention, when the design method of the industrial process simulation software based on the B / S architecture selects the connected logistics method for calculation, the functional module model class obtains the material information of the previous module based on the material flow relationship of the process simulation platform, and then uses the obtained material information as input parameters for calculation.

[0028] According to an embodiment of the design method of the industrial process simulation software based on the B / S architecture of the present invention, when the design method of the industrial process simulation software based on the B / S architecture selects not to connect the logistics method for calculation, the functional module model class directly performs single-module calculation based on its own configuration parameters.

[0040] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings below are only some examples or embodiments of the present application. For those of ordinary skill in the art, without creative efforts, the present application can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the figures represent the same structure or operation.

[0041] As shown in this application and the claims, unless the context clearly indicates otherwise, words such as "a", "an", "one", and / or "the" are not specifically singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0042] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values described in these embodiments do not limit the scope of this application. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant field may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0043] When detailing the embodiments of the present invention, for the convenience of description, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the said schematic diagrams are only examples and should not limit the scope of protection of the present invention here. In addition, in actual production, three-dimensional spatial dimensions of length, width, and depth should be included.

[0044] In the description of this application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this application; the orientation words "inside, outside" refer to the inside and outside relative to the outline of each component itself.

[0045] For ease of description, spatial relationship terms such as "below", "beneath", "lower than", "under", "above", "on", etc. may be used herein to describe the relationship of one element or feature shown in the drawings to other elements or features. It will be understood that these spatial relationship terms are intended to encompass other directions of the device in use or operation, in addition to the directions depicted in the drawings. For example, if the device in the drawing is flipped, the direction of the element described as "below" or "beneath" or "under" other elements or features will be changed to "above" the said other elements or features. Thus, the exemplary terms "below" and "under" can encompass both the upper and lower directions. The device may also have other orientations (rotated 90 degrees or in other directions), so the spatial relationship descriptive terms used herein should be interpreted accordingly. In addition, it will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or there can be one or more intervening layers.

[0046] In the context of the present application, the structure in which the described first feature is "on" the second feature may include embodiments in which the first and second features are formed in direct contact, or may include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

[0047] It should be understood that when a component is referred to as being "on another component", "connected to another component", "coupled to another component", or "in contact with another component", it can be directly on, connected to, or coupled to, or in contact with the other component, or there may be an intervening component. In contrast, when a component is referred to as being "directly on another component", "directly connected to", "directly coupled to", or "directly in contact with" another component, there is no intervening component. Similarly, when the first component is referred to as being "electrically in contact with" or "electrically coupled to" the second component, there is an electrical path allowing current flow between the first component and the second component. The electrical path can include capacitors, coupled inductors, and / or other components allowing current flow, even if there is no direct contact between the conductive components.

[0048] In addition, it should be noted that the use of terms such as "first" and "second" to define components is merely for the convenience of distinguishing the corresponding components. Without further statement, the above terms have no special meaning, and thus should not be construed as limiting the scope of protection of the present application. In addition, although the terms used in the present application are selected from well-known and commonly used terms, some of the terms mentioned in the description of the present application may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the present description. In addition, it is required to understand the present application not only through the actual terms used, but also through the meaning implied by each term.

[0049] An embodiment of a design method for an industrial process simulation software based on the B / S architecture is disclosed herein. Figure 1 It is a flowchart showing an embodiment of the design method for an industrial process simulation software based on the B / S architecture of the present invention. Please refer to Figure 1 The following is a detailed description of each step of the design method for an industrial process simulation software based on the B / S architecture.

[0050] Step S1: Analyze the requirements of the industrial process simulation software and design the function modules and performance indicators of the industrial process simulation software.

[0051] Step S2: Adopt the B / S architecture and build the industrial process simulation software framework based on the designed function modules and performance indicators.

[0052] In this embodiment, in order to build an industrial process simulation software based on the B / S (Browser / Server) architecture, first, the requirements of the user's industrial process simulation software need to be analyzed to determine the function modules and performance indicators of the simulation software. Then, based on the B / S architecture, the industrial process simulation software framework is built according to the determined function modules and performance indicators. Among them, the industrial process simulation software framework includes a front-end interface, a back-end server, a database, a bottom-layer computing engine, and a communication protocol.

[0053] Specifically, in this embodiment, the front-end interface is used to provide the canvas built when designing the flow chart. Among them, when developing the front-end interface, the user can use technologies such as HTML, Vue, and JavaScript to develop the user-interactive front-end interface, so as to design the canvas for building the flow chart through the front-end interface. The back-end server is used to implement the business logic between the function modules of the industrial process simulation software. When developing the back-end, the back-end server programming language is used to implement the business logic. The database is used to provide the storage space for the industrial process simulation software. Among them, when designing the database structure, a relational or non-relational database can be used to store data. The bottom-layer computing engine is used to provide the computing power required for the function modules of the industrial process simulation software to perform process calculations, so as to implement the thermodynamic system and unit operation calculation functions. The communication protocol is used to establish a communication mechanism between the front-end interface, the back-end server, and the database. For example, the HTTP / HTTPS protocol is adopted and combined with WebSocket to achieve real-time communication to ensure that the user can obtain instant feedback during the process simulation.

[0054] Thus, the user interacts with the front-end interface through a browser and receives the data and operation instructions input by the user through the front-end interface. Each operation of the user on the front end will generate corresponding requests, and these requests communicate with the back-end server through the HTTP / HTTPS protocol. After being parsed by the back end, these requests call the underlying computing engine to execute complex process simulation calculations to complete the computing tasks, and the calculation results are returned to the front-end interface for display through the same communication mechanism. The underlying computing engine is the core for executing simulation calculations and is responsible for processing the calculation of thermodynamic properties and unit operations in the process simulation. At the same time, a database is used to store data, including user data, model parameters, simulation results, and so on.

[0055] Step S3: Integrate each functional module based on the established industrial process simulation software framework to obtain a preliminary industrial process simulation software.

[0056] In this embodiment, when designing the functional modules of the industrial process simulation software, first formulate the corresponding module integration specifications based on the industrial process, and then design each functional module according to the module integration specifications. Among them, the module integration specifications include data interaction specifications, interface setting specifications, performance testing specifications, exception handling specifications, software version specifications, and software security specifications. Through these specifications, the designed functional modules are standardized, reducing compatibility errors during integration.

[0057] In addition, when designing each functional module according to the module integration specifications, integrate the designed functional modules into the industrial process simulation software framework to obtain a preliminary industrial process simulation software. Figure 2 is a step flowchart showing an embodiment of integrating the functional modules of the present invention into the industrial process simulation software framework. Please refer to Figure 2 , and the following is a detailed description of each step of integrating the functional modules into the industrial process simulation software framework.

[0058] Step S31: Based on the existing logistics class, create a model class for the new functional module, and reconstruct the created model class according to the simulation calculation function of the functional module.

[0059] In this embodiment, before module integration, first create a model class for the new functional module based on the existing logistics class, and then reconstruct the created model class according to the simulation calculation function of the functional module. The simulation calculation function of the functional module can be replicated through the reconstructed model class. Among them, the simulation calculation function of the functional module includes a functional interface and calculation logic. By reconstructing the created model class according to the parameter configuration and calculation method of the functional module, a model class that replicates the simulation calculation function of the functional module can be obtained.

[0060] Specifically, in this embodiment, the functional module of the industrial process simulation software includes a functional interface and a calculation logic. When reconstructing the model class, the newly created model class is reconstructed according to the parameter configuration and calculation method of the functional module of the industrial process simulation software, so as to obtain a functional module model class that inherits the simulation calculation function of the functional module. Among them, the simulation calculation function includes thermodynamic property calculation, logistics state calculation, gas-liquid equilibrium calculation, liquid-liquid equilibrium calculation, and gas-liquid-liquid phase equilibrium calculation. These simulation calculation functions are encapsulated into the functional module in the form of components, so as to realize the replication of these simulation calculation functions into the industrial process simulation software based on the B / S architecture.

[0061] Step S32: Customize the connection relationship of the newly created model class, and select the calculation method of the functional module model class by selecting the required connection relationship.

[0062] In this embodiment, after the preliminary construction of the functional module model class is completed through the above step S31, for the calculation method of the functional module model type, it is also necessary to customize the connection relationship of the functional module model class according to the material flow relationship of the process simulation platform and the simulation calculation function of the functional module, and then select the calculation method of the dedicated model class by selecting the connection relationship of the functional module model class.

[0063] Among them, the connection relationship of the functional module model class includes connecting logistics relationship and not connecting logistics relationship. When the connection logistics method is selected for calculation, the functional module model class will be associated with the material flow in the process simulation platform, obtain the material information of the previous module according to the material flow relationship of the process simulation platform, and then use the obtained material information as input parameters for calculation, and transmit the calculated material information to the next module in the process through the logistics of the process simulation platform, so as to be highly coupled with the entire process in the process simulation platform. If the non-connection logistics method is selected for calculation, the functional module model class does not participate in the material flow in the process of the process simulation platform, independently receives the input material parameters, performs simulation according to its own configuration parameters, executes the calculation and generates the result. This non-connection logistics method of module independent operation can ensure that the functional module model class can perform simulation calculation without connecting logistics, and maximally guarantee the functions of the original functional module.

[0064] Step S33: Customize the collection principle between the industrial process simulation software and the functional module, and convert and adapt the materials of the industrial process simulation software and the materials of the functional module model class through the customized collection principle.

[0065] In this embodiment, after customizing the connection relationship during the calculation of the function module model class through the above step S32, in order to ensure the correct transfer of material information between the process simulation platform and the function module model class, it is also necessary to customize the aggregation principle between the process simulation platform and the function module according to the material information of the function module, the material information of the process simulation platform, and the logistics relationship between the modules. The materials of the process simulation platform and the function module model class are converted and adapted through the customized aggregation principle. Among them, the aggregation principle includes the material attribute aggregation principle, the data format aggregation principle, the unit conversion aggregation principle, and the material name aggregation principle.

[0066] Specifically, in this embodiment, for the material attribute aggregation principle in the aggregation principle, it generally includes the following four parts:

[0067] The first part: preliminary large category classification. When customizing the material attribute aggregation principle, it is first necessary to aggregate the material attributes of the material information in the process simulation platform and the function module model class, and classify them into preliminary large categories according to the nature and use of the materials. Taking the ethylene cracking furnace function module model class as an example, the various cracked materials are classified according to their nature and use, for example, they are preliminarily classified according to hydrocarbons, aromatic hydrocarbons, alcohols, ketones, acids, etc., so as to complete the large category classification of the materials.

[0068] The second part: detailed small category classification. After completing the large category classification, it is also necessary to further classify the materials in the higher large categories.

[0069] The third part: combined aggregation. After completing the detailed small category classification, it is also necessary to combine the materials with relatively high similarity.

[0070] The fourth part: mixed aggregation. After completing the combined aggregation of the materials, further aggregation is also required for some materials that need to be mixed.

[0071] In addition, in this embodiment, after the function module model class completes the calculation, in order to convert the material information in the calculation result into the process simulation platform, it is also necessary to re-aggregate the calculation result, and re-aggregate the material information contained in the calculation result back into the original category according to the above material information conversion and aggregation principle, and finally convert the material information in the calculation result into a form that can be displayed by the process simulation platform.

[0072] Step S34: Based on the business layer interface of the function module model class of the industrial process simulation software, integrate the function module model class for calculation through the business layer interface.

[0073] In an embodiment, after formulating the collection principle between the functional module model class and the process simulation platform through the above step S33, it is also necessary to develop a dedicated business layer interface in the process simulation platform according to the functional module model class, and successfully integrate the functional module model class on the process simulation platform through the interface developed by the business layer and the corresponding software performance test. In subsequent process simulation calculations, only the business layer interface needs to be called to call the functional module model class for calculation.

[0074] Step S4: Test the industrial process simulation software based on performance indicators and industrial processes, and deploy the tested industrial process simulation software to the application server for release and application.

[0075] In this embodiment, after constructing the industrial process simulation software based on the B / S architecture through the above steps, it is also necessary to conduct functional testing, performance testing, and security testing on the industrial process simulation software based on the B / S architecture to ensure software quality, and then deploy the tested industrial process simulation software to the application server for release, and provide continuous technical support and update services.
