【摘要】：中国电力设计行业,早已广泛使用三维工厂设计软件进行三维建模,软件会自动检查碰撞并出施工图和材料报表。然而在改扩建电厂中,原始资料早已丢失不全或经历改造后资料未更新而无法使用。而传统的勘察测量方式暴露出精度低、误差大、可复用性低、差旅成本高等问题,技术成熟的三维激光扫描恰好可以弥补传统勘察测量的不足。当下的三维激光扫描硬件厂家都采用自家的还原软件,通过和当前国内电力设计院广泛使用的AVEVA公司的Plant Design Management System (PDMS)三维工厂设计系统的现有接口,还原的电厂模型都是非智能模型,无法在PDMS中进行模型编辑,更不能出管道ISO图和材料报表来施工。所以电力设计院还需要后期大量的人工操作,将电厂非智能模型中的管道和钢结构重新调整为具有PDMS三维工厂设计系统后台元件等级信息的智能模型。本文主要是针对上述设计需求,采用面向对象的编程技术,以目前中国电力设计院广泛使用的AVEVA PDMS软件和国外三维激光扫描软件LFM Modeller作为开发平台,进行相关智能模型的软件接口的开发与实现,该接口软件以AVEVA Programmable Macro Language (PML)作为开发语言环境。软件接口通过三维激光点云还原软件重新建模,并调用AVEVA PDMS后台元件等级信息,实现激光点云还原后的三维模型在PDMS中可以编辑,并生成ISO图和材料报表。该软件接口实现了可视化显示界面,将PDMS中导出的元件等级信息在独立程序中读取出来,并提供自动和手动两种方式,将元件类型在AVEVA PDMS软件和LFM Modeller软件直接进行匹配。最后,凭借PDMS智能化的出图和材料报表的强大功能,可以大幅度提高工程师的工作效率,最终减少国内电力设计院在改扩建电厂项目中的勘察设计成本,提升自身的技术实力和竞争能力。
[Abstract]:In China's electric power design industry, 3D factory design software has long been widely used for 3D modeling. The software will automatically check the collision and produce construction drawings and material reports. However, in the reconstruction and expansion power plant, the original data have long been lost or the data after transformation have not been updated and can not be used. However, the traditional survey and measurement methods expose some problems, such as low precision, large error, low reusability, high travel cost and so on. 3D laser scanning with mature technology can just make up for the shortcomings of traditional survey and measurement. At present, 3D laser scanning hardware manufacturers use their own reduction software, through the existing interface with the Plant Design Management System (PDMS) 3D factory design system of AVEVA Company, which is widely used in domestic power design institutes. The restored power plant models are non-intelligent models, which can not be edited in PDMS, let alone pipeline ISO diagrams and material reports for construction. Therefore, the power design institute still needs a lot of manual operation in the later stage, and the pipeline and steel structure in the non-intelligent model of the power plant are readjusted to the intelligent model with the background component level information of the PDMS 3D factory design system. In this paper, according to the above design requirements, the object-oriented programming technology is adopted, and the AVEVA PDMS software widely used by China Electric Power Design Institute and the foreign three-dimensional laser scanning software LFM Modeller are used as the development platform. The software interface of related intelligent model is developed and implemented, and AVEVA Programmable Macro Language (PML) is used as the development language environment. The software interface is re-modeled by 3D laser point cloud reduction software, and the level information of AVEVA PDMS background components is called to realize that the 3D model after laser point cloud reduction can be edited in PDMS, and the ISO diagram and material report form can be generated. The software interface realizes the visual display interface, reads the component level information exported in PDMS in the independent program, and provides both automatic and manual ways to match the component types directly in AVEVA PDMS software and LFM Modeller software. Finally, with the powerful function of PDMS intelligent drawing and material report, the working efficiency of engineers can be greatly improved, and the investigation and design cost of domestic electric power design institute in the reconstruction and expansion power plant project can be reduced. Enhance their own technical strength and competitiveness.
