Description

[0001] The present invention relates to a method for constructing an open BIM system supporting a plurality of heterogeneous computing platforms and interoperable with each other, interoperability between other fields}

The present invention relates to a method for constructing an open BIM system based on a cross platform that supports a plurality of heterogeneous computing platforms and interoperability of data among other fields, more specifically, Compatible and capable of running on a variety of computing platforms, allowing users to create BIM data regardless of the computing platform or field, and supporting a number of heterogeneous computing platforms that allow users to share and exchange BIM data with one another And to a method for constructing an open BIM system based on a cross platform capable of interoperability of data between other fields.

Conventionally, as a computer application for creating drawings for various designs in industrial fields such as construction, civil engineering, mechanical, electrical, electronic, etc., drawings are created by a computer, the created drawings are stored in a computer in the form of files, A two-dimensional computer aided design (CAD) system capable of recalling a drawing file has been developed and actively used.

 However, since the drawings made using the conventional two-dimensional CAD system as described above are difficult to show the three-dimensional shape of objects, there are limitations in expressing realistic shapes of objects, so that information loss Resulting in unexpected increases in costs and air delays.

In order to solve the above problems, a three-dimensional CAD system capable of three-dimensional modeling has been introduced and widely used, but the drawings created by using the three-dimensional CAD system are inconsistent due to the individual creation of each drawing, Has become unclear and compatibility has deteriorated.

In order to solve the above problems, a concept called BIM (Building Information Modeling) has been introduced. The BIM system is a BIM system, and the BIM system is a BIM application.

At present, an imaginary BIM system is widely used as an alternative to overcome the problems of the above-mentioned three-dimensional CAD system.

BIM is a digital model that provides a reliable basis for making decisions during the life cycle of a facility by physical or functional characteristics of the facility object in all construction fields, including construction, civil engineering, and plant, Lt; / RTI > BIM is divided into closed BIM and open BIM depending on the range of BIM data compatibility. Closed BIM is a concept that BIM data is compatible only within the same company product line. On the other hand, open BIM is a system that allows various subjects to share and exchange BIM data of international standard established by ISO (International Organization for Standardization) and buildingSMART International (interoperability and compatibility of BIM data) This means the concept used to effectively achieve the purpose of the introduction.

In all open BIM-based BIM systems, BIM data in internationally recognized and accepted standard formats is used to share and exchange BIM data among various BIM systems in different company product families. Therefore, when the BIM system based on the open type BIM is used in various designs, the design and drawing making are integrated, and the created BIM data is fetched, so that the existing BIM data can be connected and interlocked, Although the above-mentioned problems, which have been a problem in using the 3D CAD system, are mostly solved, the BIM system based on the open BIM currently produced has the following problems.

First, as BIM applications that are software for open BIM systems are being developed separately for different versions of a number of computing platforms, developing a BIM application separately for a number of different computing platform versions, There is a problem that the time increases.

Here, a platform refers to a hardware or software on which a computer system is changed by changing the meaning of a bowl, a land, a stage, or a stage, and generally refers to a system on which an application can be executed. In recent years, the term platform is widely used not only in the computer environment but also in other fields, and is called a computing platform in order to distinguish the platform used in the computer field from the platform used in other fields.

 Most of the applications in the past have been designed to run only on certain computing platforms, but recently, some applications have been designed to run on other computing platforms through an open interface. This means that applications can run on other computing platforms as well as on certain computing platforms. Whenever possible, these applications are referred to as cross-platform or multi-platform applications.

Second, since BIM data of the different company product families developed by software of the open BIM system is compatible with only the BIM data whose data file format is the neutral format or the standard format, when the BIM data is created and stored, Of BIM data and also in BIM data in neutral format or standard format that is compatible with other BIM applications in other product families. However, unlike the BIM data in which the data file format is the neutral format or the standard format, the BIM data in which the data file format is the original format contains all the information at the time of creating the BIM data, There is a problem that complete data compatibility can not be achieved even if the BIM applications of different company product families are compatible with the BIM data of the neutral format or the standard format. As a result, when you want to use BIM data created in a BIM application in a specific company's product family in a BIM application in another company's family, you need to perform separate data conversion operations or data rewriting It is troublesome to work.

Third, users of BIM applications that make open BIM system software do not take into consideration other fields when creating BIM data. In many cases, users create BIM data separately for each field. Therefore, when creating BIM data for specific fields, There is a problem that it is difficult to use the BIM data created for the other fields because it does not fit the characteristics of the field in which the BIM data is created.

 ≪ Embodiment 1 >

 As shown in FIG. 4A, a method for constructing an open BIM system supporting a plurality of heterogeneous computing platforms according to the first embodiment and cross-platform compatible with other fields is as follows.

The first step S110 is to build a cross platform development environment 20 and select one or more of the integrated development languages of the cross platform development environment 20 to perform source coding of the cross platform BIM application 10.

The second step S120 is to compile the source code of the cross platform BIM application 10 coded in the first step S110 with the compiler 30 according to the integrated development language to easily convert it into a machine language, (Intermediate Language) code, which is an intermediate language that is not an intermediate language, and metadata for the IL code, and stores it in an assembly, which is an executable file, on a disc.

The third step S130 is a step of building the cross-platform BIM application 10 with the assembly stored in the disk in the second step S120.

As shown in FIG. 6, the first step (S110) includes the detailed steps of setting a BIM standard protocol at the time of building an open BIM system based on a cross platform according to the present invention.

Step 1a (S510) is a step of setting a field for implementing the BIM and performing a source coding of a data file format of the object model for each field and a structure for setting the structure of the data file name.

Step 1b (S520) is a step of source-coding a part for setting a task level (LOS) for each field set in the step 1a (S510).

The first c step S530 is a step of source-coding a part for setting the information depth LOD for each LOS of each field set in the step 1b (S520).

The first d step S540 includes a step of assigning a code system to the LOS of each field set in the steps 1b to 1c (S520 to S530) and the information depth (LOD) of each field of operation (LOS) As shown in FIG.

Step 1e (S550) is a step of generating an object model corresponding to the information depth (LOD) for each task level (LOS) of each field and source-coding a part for giving attributes to the generated object model.

Step 1f (S560) is a step of source-coding a portion defining the reference of the object model generated in the first e step (S550).

In the first g step S570, the object model generated in the first e step S550 is categorized by object and attribute to source-code a part for creating an information classification system (object classification system and attribute classification system).

The first step S580 is a step of source-coding a part for verifying mutual compatibility among the object models generated in the first e step S550.

In step S510, the data file format of the object model for each field is set to a neutral format compatible with IFC (Industry Foundation Classes) neutral format.

In the first step S110, the BIM data of the IFC-neutral format created and generated by another BIM application and the BIM data created and generated by the cross-platform BIM application 10 satisfy the BIM quality criteria And a first i step (S590) of source coding the quality review tool to be reviewed.

The first embodiment will be described in detail in each step as follows.

A computing platform is a combination of hardware and software used to execute applications, and generally includes a computer architecture, an operating system (OS), a program language, a runtime library, and a GUI (Graphic User Interface) Because computing platforms are often distinct, they are often referred to as operating systems (OSs).

In the present invention, a computing platform refers to an operating system (OS) as a target platform 50 on which applications are to be executed.

Currently, typical operating systems include computer operating systems such as Windows, Mac OS, Unix, and Linux, embedded computer operating systems such as Windows Embedded and Embedded Linux, iOS, Android (Android), Windows Phone, and Windows RT.

As shown in FIG. 5A, in the first step S110, a cross platform development environment 20 is constructed, and integrated development is performed in the cross platform development environment 20 so as to satisfy the Common Language Specification (CLS) The BIM application 10 may be one or more of the following languages: the .NET Framework or the .NET Compact Framework. , And Mono Framework (Mono Framework).

Meanwhile, the cross-platform development environment 20 includes a conventional method of inputting a source code using an editor such as a notepad, storing the file as a file, and compiling the source code by directly driving the compiler according to the integrated development language You can use the development environment, but you can use the cross-platform development IDE (Integrated Development Environment) to process all the tasks involved in developing the cross-platform BIM application (10), including coding, debugging, Is much more advantageous in many ways.

The representative cross-platform development IDE includes a .NET IDE capable of developing a cross-platform application running on the .NET Framework or the .NET Compact Framework, which is a cross platform execution environment 40, And a mono IDE capable of developing a cross-platform application running on a mono framework (execution environment 40).

In the above mentioned .NET IDE, source coding is performed by selecting one or more integrated development languages compatible with each other in the .NET IDE such as C #, C ++ / CLI, VB.NET, F #, etc. The cross- It runs on an MS Windows-based computing platform with a framework (.NET Framework) or a .NET Compact Framework.

In the mono IDE, source coding is performed by selecting one or more integrated development languages compatible with each other in a mono IDE such as C #, C ++ / CLI, VB.NET, F #, and vala. Runs on a variety of computing platforms with a mono framework.

The cross-platform applications developed in the above-mentioned .NET IDE can be run on various MS Windows based computing platforms such as Windows, Windows Embedded, Windows Phone, and Windows RT.

The cross-platform application developed with the above-mentioned mono IDE can be used not only in various MS Windows based computing platforms such as Windows, Windows Embedded, Windows Phone, and Windows RT, but also Mac OS, Unix, Linux, Linux, iOS, Android, and many other non-MS-based computing platforms.

In the second step S120, the IL code is also called CIL (Common Intermediate Language) code or MSIL (Microsoft Intermediate Language) code. When the source code coded in the first step S110 is compiled into the compiler according to the integrated development language, it is compiled into the IL code conforming to a Common Language Infrastructure (CLI) specification called a common language base, The metadata is separate data explaining the nature of the IL code.

The metadata for the IL code and the IL code is stored in an assembly, which is an executable file, and is stored on a disk. The general extension of the assembly is .exe or .dll.

The assembly is composed of one or more modules, wherein one file corresponds to one module, and when a plurality of modules constitute one assembly, one of the plurality of modules necessarily manages a list of other modules Manifest data must be included.

In the third step S 130, when building the cross-platform BIM application 10 using the assembly, it is common to use a distributed application such as ClickOnce, Windows Installer, InstallShield, or the like.

If the open platform BIM system is constructed by developing the cross platform BIM application 10 in the cross platform development environment 20 as in the first through third steps S110 through S130, As shown in FIG. 5a, the cross-platform BIM application 10 is distributed to the user and the user acquires the cross-platform BIM application 10 and installs it on the target platform 50 for use. Here, the user may first install the cross platform execution environment 40, which is the execution base of the cross platform BIM application 10, on the target platform 50 before installing the cross platform BIM application 10 on the target platform 50, .

Since the cross platform BIM application 10 distributed to the user is not dependent on the computing platform, it can be installed anywhere on the computing platform on which the cross platform execution environment 40 is installed. However, since the cross-platform execution environment 40 is dependent on the computing platform, only a cross-platform execution environment 40 for the corresponding computing platform may be installed in the specific computing platform.

The user installs the cross platform execution environment 40 and the cross platform BIM application 10 that are the execution base of the cross platform BIM application 10 on the target platform 50 as described above and then executes the cross platform BIM application 10).

When the user executes the cross platform BIM application 10 on the target platform 50, a virtual machine CLR (or Mono runtime) is created in the .NET (or Mono) Framework, which is the cross platform execution environment 40 And the JIT (Just In Time) compiler converts the IL code in the assembly, which is an executable file, into a native code, so that the native code is executed.

As shown in FIG. 6, detailed steps for setting a BIM standard framework rule at the time of building an open BIM system based on a cross platform according to the present invention including the first step (S110) will be described in detail. same.

In step S510, various fields for implementing BIM such as architecture, civil engineering, environment, landscape, information communication, electric / electronic, and machine are set, and the structure of the data file format and the data file name of the object model for each field is set The source code is coded.

In step S510, the data file format of the object model for each field is set to a neutral format compatible with the IFC neutral format.

Here, if the data file format of each field object model is set to the neutral format, BIM data can be shared and exchanged with BIM applications of other company product families.

Typical neutral formats include IFC neutral format and XML-based neutral format.

The IFC Neutral Format is an international standard format that has been developed and widely used for all BIM applications for sharing and exchanging BIM data through the IFC neutral format.

However, the IFC neutral format has a limitation that there may be some information loss when converting BIM data of original format to BIM data of IFC neutral format for BIM data compatibility between BIM applications of different company product families.

Meanwhile, XML (eXtensible Markup Language) is a kind of computer language in which information exchange is rapidly spreading through the web due to the development of information technology and the spread of the Internet, and is developed by the need of standardized information technology which is not restricted by specific hardware or software .

Currently, XML has been adopted as a data format standard distributed on the web at home and abroad, and has been adopted as a web-based information exchange standard in almost all applications such as electronic commerce, finance, science, education, information technology and medical care.

At present, neutral formats such as ifcXML, gbXML, CityGML, and LandXML based on XML are widely used.

The above-mentioned ifcXML, gbXML, CityGML, and LandXML are adopted as data standard formats in various fields and widely used, but they have limitations.

For example, ifcXML and gbXML are developed with a focus on the use of architecture, there is a limit to expression in the civil engineering field. CityGML is developed to be used in the GIS field, and there is a limitation in expressing general buildings and civil engineering facilities. It is developed to be used in the engineering field, and there is a limit to expression of the facility information.

In the first step S510, the data file format of the object model for each field is set to a neutral format compatible with the IFC neutral format, so that the data file format of the object model for each field is converted into the neutral format original format or the standard format BIM data can be unified in the original format so that BIM data in the original format can be shared and converted to BIM data in the original format without converting BIM data in the original format into BIM data in the IFC neutral format when sharing and exchanging BIM data with BIM applications So that various fields can be expressed in a data file format unified by the original format of the neutral format or the original format of the standard format.

In the first step S520, a part for setting a task level (LOS) for each field set in the first step S510 is source-coded.

Here, the business level (LOS) is a level of service, which means the kind of information to be served.

For example, as shown in FIG. 7, the LOS of the architectural field is usually classified into three categories: Plan, Design, Engineering, Construction, Maintenance Repair), and Diposal (discard).

The LOS of each field is basically based on Plan, Design, Construction, Maintenance, though it may be a little different depending on the characteristics of each field.

In the first c step (S530), a part for setting an information depth (LOD) for each LOS of each field set in the step 1b (S520) is source-coded.

Here, the information depth (LOD) is a level of detail, and refers to a level of information expression for the object model.

As the depth of information (LOD) deepens, the object model is abstracted because the information is more detailed, the more the information to be expressed becomes, the more the object model becomes concrete and the information depth (LOD) becomes shallower.

For example, as shown in FIG. 7, when the information depth LOD is deepened when the wall Wall is expressed, the wall information becomes more specific as the depth information LOD becomes more detailed, and the information depth LOD becomes shallow Accordingly, the wall information is simplified and the wall is abstracted.

In the first step S540, a code system is assigned to the LOS of each field set in the steps 1b to 1c (S520 to S530) and the information depth (LOD) of each field of operation (LOS) Quot; portion "

In order to interoperate with the object model, it is necessary to decide which business stage (LOS) and which information depth (LOD) to exchange the object model. For this purpose, the LOS of each field and the LOS ) Code information must be assigned to the depth of information (LOD).

In the first e step S550, an object model corresponding to an information depth (LOD) for each task level (LOS) of each field is generated and a part for assigning attributes to the generated object model is source-coded.

An object model corresponding to the information depth (LOD) of each business field (LOS) required for creating BIM data is generated and an attribute is given to the generated object model.

In the first f step S560, a portion defining a reference of the object model generated in the first e step S550 is source-coded.

By defining a reference to the object model generated in the first e step S550, an object model similar to an existing object model is modeled by reference to an existing object model without newly generating an object model . This eliminates duplication of the object model and ensures recyclability because it is necessary to model the object model by changing the expression of the existing object model by reference (reference) without having to newly create a similar object model.

On the other hand, if a library is constructed by using an object model that has been created as a reference object model and a reference object model as a reference object model so that the library can be used when creating BIM data, This becomes easier.

In the first g step S570, the object model generated in the first e step S550 is categorized according to objects and attributes to source-code a part for creating an information classification system (object classification system and attribute classification system).

By creating an information classification system (object classification system and attribute classification system) by classifying the object model generated in the first e step (S550) according to objects and attributes, the object model necessary for creating BIM data at the time of creating BIM data Can be easily found and retrieved through the information classification system.

In the first h step S580, a part for verifying interoperability between the object models generated in the first e step S550 is source-coded.

Since the interoperability between the object models generated in the first e step (S550) is verified beforehand, the object models retrieved for creating the BIM data at the time of creating the BIM data are incompatible with each other, causing problems in the creation of the BIM data To prevent them from doing so.

In the first step S110, the BIM data of the IFC-neutral format created and generated by another BIM application and the BIM data created and generated by the cross-platform BIM application 10 satisfy the BIM quality criteria And a first step (S590) of source coding the quality review tool to be reviewed.

BIM data of an IFC neutral format created and created in a BIM application that is software of another open BIM system is called up from the cross platform BIM application 10 which is a software of a cross platform based open BIM system according to the present invention In order to do this, a BIM data quality verification process that examines whether BIM data satisfies the BIM quality criteria is required.

In order to distribute the BIM data created and generated in the cross-platform BIM application 10, which is a software of the cross platform based open BIM system according to the present invention, it is first checked whether the BIM data satisfies the BIM quality criteria BIM data quality verification process must be performed, and a quality review tool is needed for this.

The quality review tool performs a quality review work on BIM data to check three qualities of physical information quality, logical information quality, and data quality.

Here, the physical information quality refers to quality that can be visually confirmed such as geometric data, shape completeness, collision between objects, proximity, proper spacing, dimension display, and the like.

Logical information quality refers to the fulfillment of logical requirements such as laws, standards, guidelines, and quantity information.

Data quality refers to whether data is correctly input to secure quality of object element, IFC version, shape, object field, and object attribute.

In addition, the quality review tool outputs the quality review results in various forms such as a chart, a graph, a report, and a check list after the quality review work is performed.

Based on the quality review result, the BIM data of the IFC-neutral format created and created in the BIM application software of the other open BIM system is converted into the cross platform BIM application software The BIM data created and generated by the cross platform BIM application 10, which is software of the cross platform based open BIM system according to the present invention, is distributed to the outside It is decided whether or not it can be done.

 ≪ Embodiment 2 >

Details of the same parts as those of the first embodiment will be omitted.

As shown in FIG. 4B, a method for constructing a cross platform based open BIM system supporting a plurality of heterogeneous computing platforms according to the second embodiment and interoperable with each other is as follows.

The first step S210 is the step of constructing a cross platform development environment 20 and selecting one or more of the integrated development languages of the cross platform development environment 20 to perform source coding of the cross platform BIM application 10.

The second step S220 compiles the source code of the cross platform BIM application 10 coded in the first step S210 with the compiler 60 for each target platform to generate a native Generate code and store it on disk.

The third step S230 is a step of building the cross-platform BIM application 10 with the native code stored in the disk in the second step S220.

The second embodiment will be described in detail below.

Since the first step is the same as the first embodiment, a detailed description thereof will be omitted.

As shown in FIG. 5B, in the second step S220, the target platform-specific compiler 60 can easily convert the cross-platform BIM application 10 source code into a machine language, And AOT (Ahead of Time) compilation method for converting the language code into the native code that can be executed by each target platform 50. [

Typically, the target platform-specific compiler 60 includes .NET Native, which converts C # code into the native code that can be executed in an MS Windows-based computing platform, MonoTouch, which converts C # code into native code that can be executed in an iOS- , And MonoDroid, which converts C # code to the native code that can run on an Android-based computing platform.

 ≪ Third Embodiment >

The detailed description of the same parts as those of the first embodiment or the second embodiment will be omitted.

As shown in FIG. 4C, a method for constructing a cross platform based open BIM system supporting a plurality of heterogeneous computing platforms according to the third embodiment and interoperable with each other is as follows.

The first step S310 is the step of constructing the cross platform development environment 20 and performing source coding of the cross platform BIM application 10 in the development language of the cross platform development environment 20.

The second step S320 is to compile the source code of the cross platform BIM application 10 coded in the first step S310 with the compiler 70 of the development language and to convert it into a machine language, (Bytecode), which is a non-intermediate language, and storing it on a disk.

The third step S330 is a step of building the cross-platform BIM application 10 with the bytecodes stored in the disk in the second step S320.

The third embodiment will be described below in detail.

5C, the cross-platform development environment 20 is established in the first step S310 and the cross platform development environment 20 is installed in the cross platform development environment 20 in the Java language satisfying the JLS (Java Language Specification) The BIM application 10 performs source coding. A typical cross platform development environment 20 is a Java Development Kit (JDK).

Meanwhile, the cross-platform development environment 20 includes a conventional development method of inputting a source code by using an editor such as a notepad, storing it as a file, and compiling the source code by directly driving the compiler of the development language in a command line window Environment but can handle all the tasks involved in developing the cross-platform BIM application (10), including coding, debugging, compiling, and deploying, using an integrated development environment (IDE) in a single integrated development environment Things are much more advantageous in many ways.

As a representative cross-platform development IDE, there is a Java IDE capable of developing a cross-platform application driven by a Java Runtime Environment (JRE)

The Java IDE performs source coding in the Java language, and the cross platform application developed in the Java IDE is run on various computing platforms in which the JRE is installed.

The cross-platform applications developed in the Java IDE are used not only in various MS Windows based computing platforms such as Windows, Windows Embedded, Windows Phone and Windows RT, but also Mac OS, Unix, Linux, Linux, iOS, Android, and many other non-MS-based computing platforms.

In the second step S320, if the source code coded in the first step S310 is compiled into a Java compiler, it is compiled into the bytecode and stored in the disk. The extension of the bytecode is .class.

In the third step S330, it is general to use a distributed application such as ClickOnce, Windows Installer, or InstallShield when building the cross-platform BIM application 10 with the bytecode.

If the open platform BIM system is constructed by developing the cross platform BIM application 10 in the cross platform development environment 20 as in the first to third steps S310 to S330, As shown in 5c, the user may distribute the cross-platform BIM application 10 and the user acquires the cross-platform BIM application 10 and installs it on the target platform 50 for use. Here, the user installs the cross platform execution environment 40, which is the execution base of the cross platform BIM application 10, on the target platform 50 before installing the cross platform BIM application 10 on the target platform 50 Should be.

Since the cross platform BIM application 10 distributed to the user is not dependent on the computing platform, it can be installed anywhere on the computing platform on which the cross platform execution environment 40 is installed. However, since the cross-platform execution environment 40 is dependent on the computing platform, only a cross-platform execution environment 40 for the corresponding computing platform may be installed in the specific computing platform.

The user installs the cross platform execution environment 40 and the cross platform BIM application 10 that are the execution base of the cross platform BIM application 10 on the target platform 50 as described above and then executes the cross platform BIM application 10).

When the user executes the cross platform BIM application 10 on the target platform 50, a Java Virtual Machine, which is a virtual machine, is loaded into the JRE, which is the cross platform execution environment 40, and a JIT (Just In Time) Converts the bytecode into native code, and the native code is executed.

As shown in FIG. 6, detailed steps of setting a BIM standard framework rule at the time of constructing an open BIM system based on a cross platform according to the present invention including the first step S310 are the same as those of the first embodiment A detailed description thereof will be omitted.

The first step S110, S210 and S310 is to build a cross platform development environment 20 and select one or more of the development languages of the cross platform development environment 20 or integrated development languages 20, Source coding, while the UI / UX part performs source coding for each target platform 50 separately.

As in the first steps S110, S210 and S310, when performing the source coding of the cross-platform BIM application 10, UI (User Interface) / UX (User Experience) Source coding, the usability of the cross-platform BIM application 10 is improved compared to when source-coding the UI (User Interface) / UX (User Experience) parts for each target platform 50 into one type, Is maximized.

Practically, it may be almost necessary to separately develop UI (User Interface) / UX (User Experience) parts for each target platform 50 when developing the cross-platform BIM application 10. [

The target platform 50 may be a variety of platforms such as Windows, Mac OS, Unix, Linux, Windows Embedded, Embedded Linux, iOS, Android, Windows Phone, (User Interface) / UX (User Experience) parts have unique characteristics for each of the target platforms 50. In addition, applications driven by the target platform 50 are also included in each of the target platforms 50 (User Interface) / UX (User Experience) part in accordance with the UI (User Interface) / UX (User Experience) Even if they are developed in a lump, there is a big problem in usability.
