Description

基于BIM技术的建筑照明一体化模拟实施方法、装置及系统
本申请要求于2019年6月14日提交中国专利局、申请号为201910515778.9、发明名称为“基于BIM技术的建筑照明一体化模拟实施方法、装置及系统”的国内申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及智能化建筑技术领域，具体涉及一种基于BIM技术的建筑照明一体化模拟实施方法、装置及系统。
背景技术
目前，在建筑的照明设计中，为了提高建筑空间的整体照明效果，通常采用建筑与照明协同设计的方式。具体的，建筑与照明的协同设计是在满足建筑功能照明的基础上，将照明器具和建筑界面(如围护结构表面等)或建筑构件(如声学构件、暖通空调构件等)融为一体的设计方式。
然而，目前的建筑照明一体化设计通常采用两种方式实现，一种方式为采用“应用程序接口”将建模软件中的建筑模型信息直接传递给照明插件，进而实现建筑照明协同设计。另一种方式为采用“信息的格式转换”，将信息转换成建筑与照明设计软件均兼容的信息格式。

具体实施方式
正如背景技术所述，目前建筑照明一体化模拟实施方法在设计集成和信息集成层面受到技术手段的限制存在欠缺和不足。通常有两大技术手段：第一种是利用“应用程序接口”，将BIM核心建模软件中的建筑模型信息 直接传递给照明插件，这一技术手段初步实现了建筑照明同界面协同设计，但受“应用程序接口”功能的限制，无法传递所有建筑照明模拟需要的信息(如材质信息等)，从而影响设计计算结果的全面性与精确性。
第二种是利用“信息的格式转换”，包括中间文件转换或公共标准转换两种方式，将信息转换成建筑和照明设计软件兼容的信息格式。具体的，BIM系统中信息的格式转换目前采用IFC(Industry Foundation Classes)标准，它将核心建模软件中的建筑模型信息，以IFC格式文件导入至照明软件，照明软件对IFC格式文件进行解析之后进行照明设计，此种方法整合了建筑性能模拟需要的所有信息，其包含建筑照明模拟的信息，还包含声环境模拟，建筑采光模拟等。由于所有信息包含许多照明模拟不需要的模型信息(如墙的厚度等)，一方面导致文件过大，导入照明软件解析时间过长；另一方面容易造成照明软件对信息解析不正确，进而导致信息丢失等问题。
目前的照明软件支持IFC格式的导入，但不支持IFC格式的导出，无法将照明信息传递回核心建模软件，导致照明与其他专业无法配合，进而无法实现信息集成；同时，受IFC格式限制，IFC格式文件不能包含灯具的光源信息，即使照明软件支持导出IFC格式，也无法将光源信息传回核心建模软件；故此种方法能够传递所有的照明用建筑模拟信息，保证了设计计算的全面性和准确性，但在设计集成所要求的同界面和信息集成所需要的照明信息层面，仍然存在不足。
另外，建筑照明一体化提出了新的指标要求(如频闪、空间亮度系数等)，因此需要在目前照明软件的模拟功能的基础上添加对应的信息和算法。综上所述，需要寻求一种新的能够适应建筑照明一体化模拟实施方法。
基于此，请参阅图1，图1为本实施例提供的一种基于BIM技术的建筑照明一体化模拟实施方法的流程示意图，该方法基于建筑照明一体化方案，整合BIM系统的“应用程序接口”和“信息的格式转换”两个技术手段，为建筑照明一体化设计建立软件平台，完成方案的模拟设计。具体的，该方法包括：
S11、基于所述BIM系统，建立照明用建筑信息模型，传递所述照明 用建筑信息模型至建筑照明一体化照明插件。
需要说明的是，在本实例中以BIM系统的核心建模软件Revit为例，利用应用程序接口Revit API和信息的格式转换两种技术手段阐述本实施例提供的一种基于BIM技术的建筑照明一体化模拟实施方法。
如图2以及图3所示，“应用程序接口”技术包含四个层面的内容，即通过Revit的应用程序接口(以下简称Revit API)的信息传递、信息解析、程序连接和程序研发。
其中，信息传递是指Revit API将Revit软件内部的信息进行提取，直接传输。信息解析是指Revit API将外界传入Revit软件或第三方应用程序(本发明实施例中指插件)的信息内容和结构进行解读，对应放置到其能够使用的位置。程序连接是指Revit API将第三方应用程序(插件)与已有相关软件的连接，完成信息再编辑后，利用第三方应用程序(插件)进行计算。程序研发是指用Revit API开发第三方应用程序(插件)。
具体的，在本实施例中，如图3所示，建筑照明一体化照明插件是在原有的照明插件的基础上，增加了“新增插件”。其中，照明插件是在BIM系统的核心建模软件上以插件形式存在的，能够进行照明设计，并能计算照度、亮度和生成效果的第三方应用程序。而新增插件能够：①传递照明用建筑信息至照明插件：具体过程包括提取建筑用照明信息，建立建筑用照明信息模型，转换建筑用照明模型文件和传递建筑用照明信息模型文件；②在照明插件已有灯具信息基础上，新增建筑照明一体化灯具信息；③整合已有的建筑与照明信息，形成建筑照明一体化模型；④新增一体化公式，并进行相应的计算设置和计算；⑤传递照明信息回BIM系统：具体过程包括提取照明信息，建立照明信息模型，转换建筑用信息模型文件和传递建筑用信息模型文件。即，新增插件是对照明插件的按照建筑照明一体化需求的二次开发。
而“信息的格式转换”技术的目的是完成两个软件(或软件与插件、插件与插件)之间信息的传递传，结合图4以及图5，包括以下三个步骤：利用Revit API将需要传递的信息先进行提取，再将信息转化成信息格式文件，最后将信息传递出去。
其中，信息格式文件应该被两个软件兼容，包括中间文件转换(本发明指中间格式文件)或公共标准转换(本发明指IFC标准格式文件)两种方式。
具体的，本实施例提供了一种基于所述BIM系统，建立照明用建筑信息模型的具体实现方法，如图6所示，包括：
S61、基于所述BIM系统，建立所述建筑照明一体化照明插件；
S62、所述建筑照明一体化照明插件获取所述BIM系统导出的目标格式的建筑信息；
S63、基于所述建筑信息，确定出照明模拟对应的照明用建筑信息；
S64、根据所述照明用建筑信息，建立所述照明用建筑信息模型。
在本实施例中，照明用建筑信息是指照明计算所用的各表面的几何尺寸、材质信息以及位置信息等建筑信息。以建筑室内为例，计算所用各表面将涉及墙、门窗、屋顶、梁柱、地面、家具、室内装饰和设备的所有可见表面。
而建立照明用建筑信息的模型的目的是将Revit软件导出的IFC格式的信息进行筛选，提取出照明模拟需要的建筑信息。例如，首先解读IFC格式文件中包含的建筑信息。然后基于该建筑信息，确定出照明模拟需要的建筑信息，定义成照明用建筑信息。之后，整合照明用建筑信息，建立照明用建筑信息模型。
进一步的，本实施例提供的建筑照明一体化模拟实施方法中，还提供了一种传递所述照明用建筑信息模型至建筑照明一体化照明插件的具体实现方法，如图7所示，包括：
S71、将所述照明用建筑信息模型转换成照明用建筑信息中间格式文件；
S72、传递所述照明用建筑信息中间格式文件至所述建筑照明一体化照明插件。
而图7的步骤是为了将BIM系统中的照明用建筑信息模型传递给照明插件，具体的，可以利用“信息的格式转换”技术将照明用建筑信息模型转换成照明用建筑信息中间格式文件，之后将照明用建筑信息中间格式文 件传递至照明插件。
然后在照明插件中，利用“应用程序接口”技术对传递来的照明建筑中间信息文件进行解析。
可见，本实施例基于BIM系统，建立预设照明一体化照明插件，然后利用建筑照明一体化插件从BIM系统已有信息中刷选照明用建筑信息，建立照明用建筑信息模型，然后，将照明用建筑信息模型转换成中间格式文件，最后将中间格式文件传递出去。
S12、根据预设建筑照明一体化设计指标，所述建筑照明一体化照明插件基于所述照明用建筑信息模型，添加建筑照明一体化灯具信息，生成建筑照明一体化设计信息模型；
该步骤的目的是按照建筑照明一体化设计指标，添加建筑照明一体化灯具信息。其中，灯具是光源和灯罩以及附件的总称，因此，本实施例中，建筑照明一体化灯具信息包括光源所对应的光学信息和灯罩以及附件对应的声学和热工信息，还可以包括灯具的位置、高度、角度等安装信息。而光学信息和安装信息用于照明计算，声学和热工信息用于配合其他专业需求。
在建筑照明一体化照明插件中，根据建筑照明一体化设计指标，在照明用建筑信息模型的基础上，利用“应用程序接口”技术添加建筑照明一体化灯具信息，形成建筑照明一体化设计信息模型。
其中，建筑照明一体化灯具信息包含照明插件中已有灯具信息和建筑照明一体化灯具新增的信息两部分。
可见，形成建筑照明一体化设计信息模型就是将BIM系统中的照明用建筑信息与建筑一体化灯具信息进行整合，形成建筑照明一体化信息模型。
S13、对所述建筑照明一体化设计信息模型进行模拟计算，生成模拟计算结果信息；
具体的，本实施例提供了一种对所述建筑照明一体化设计信息模型进行模拟计算，生成模拟计算结果信息的具体实现方法，如图8所示，包括：
S81、依据所述的预设建筑照明一体化设计指标，确定所述建筑照明一体化设计信息模型中待计算的目标建筑区域；
S82、对所述目标建筑区域设置计算网格，按照建筑照明一体化指标计算公式对所述目标建筑区域进行计算，生成所述模拟计算结果信息。
可见，本实施例可以利用“应用程序接口”技术增加建筑照明一体化指标计算公式。然后，根据建筑照明一体化指标，确定计算面或空间；在照明插件中，利用“应用程序接口”技术，在建筑照明一体化设计信息模型上设置计算网格，执行计算。
具体的，在照明插件中，基于建筑照明一体化设计信息模型，进行计算设置和执行。在本实施例中，建筑照明一体化指标包括照度、亮度、频闪、空间亮度系数等。而垂直照度、频闪、空间亮度系数是建筑照明一体化提出的新的指标。
S14、基于所述建筑照明一体化灯具信息以及所述模拟计算结果信息，建立照明信息模型；
具体的，本步骤是在建筑照明一体化照明插件中，将灯具信息与照明计算结果信息整合，建立照明信息模型。
S15、发送所述照明信息模型至所述BIM系统。
