Abstract: In order to meet the need of collaboration design on the same platform, a complete digital integration design platform needs to be built due to the rapid development of digital power plants.As an important part of digital design, 2D/3D collaborative design still exists defects:manual repeated input data and data transmission problem. By using the binary tree algorithm in computer technology, it is possible to match the two-three-dimensional model in real time without pre-coding. Based on this, the two collaborative design modes (rapid mode and precise mode) are proposed, which can greatly improve the design efficiency and design quality. A new subcontracting business model is also derived, that is three-dimensional modeling design outsourcing, which does not need to provide database and coding system.

Key words: two-three-dimensional collaboration design, intelligent matching, digital integration

摘要： 数字化电厂的发展急需搭建一个完善的数字一体化设计平台，满足多专业在同一个平台上协同设计的需求。二三维协同设计作为数字化设计的重要组成部分，一直存在人工重复录入数据，数据难以传递的问题。借用计算机技术中的二叉树算法，可以在不提前编码的前提下对二三维模型进行实时匹配。本文基于此提出了快速建模和精确建模两种协同设计模式，可以大大提升设计效率和设计质量，并衍生出三维建模设计外包，但不必提供数据库和编码系统的新的设计分包商业模式。
