20年以来,勘察设计行业的信息化是以CAD为主要内容。可以划分为四个阶段:第一个阶段是利用计算机较强的计算能力和数据处理能力,在工程设计中使用计算机解决工程设计复杂计算,优化设计方案。第二个阶段是以计算机为工具进行二维绘图,实现了以微机代替图板、丁字尺的设计手段革命。第三个阶段是对复杂的、技术要求高的大项目,进行三维模型设计,充分发挥了三维建模可渲染、可碰撞检查和修改、可出管段图、准确统计管件的优点。第四个阶段是随着网络技术的发展、高性能计算机的出现,异地、协同、虚拟设计及实时仿真应用等开始逐步应用。未来,勘察设计行业信息化的发展方向就是网络平台上的协同设计、协同建造。这为我们提出了新的亟待解决的问题。
Since 20 years, the survey and design industry information is based on CAD as the main content. Can be divided into four stages: The first stage is the use of computer strong computing power and data processing capabilities in engineering design using computer to solve complex engineering design calculations, optimize the design. The second stage is a two-dimensional computer graphics as a tool to achieve the computer instead of drawing board, T-shaped ruler revolution in design tools. The third stage is for complex, high technical requirements of large projects, the three-dimensional model design, give full play to the three-dimensional modeling can be rendered, collision check and modify, out of pipe sections, the advantages of accurate statistics of the pipe. The fourth stage is with the development of network technology, the emergence of high-performance computers, remote, collaborative, virtual design and real-time simulation applications began to gradually apply. In the future, the development direction of the survey and design industry informationization is the collaborative design and collaborative construction on the network platform. This puts forward new problems that we must solve immediately.
