激光水准面自动测控技术是七十年代发展起来的新技术。它应用于建筑施工实时测量,提高水准测量效率、精度;节约工时与材料。它还应用于大面积土方工程、农田平整及土地改良工程。我国在七十年代初期开始研究建筑工程激光水准面自动测控系统,本文介绍该系统的构造原理,以及其在刚性,柔性滑模平台上的应用实例。 Laser level automatic measurement and control technology is developed in the seventies new technology. It is used in real-time measurement of construction to improve the level of measurement efficiency and accuracy; save time and materials. It is also used in large areas of earthworks, farmland leveling and land improvement projects. In the early 1970s, China started to study the laser level automatic measurement and control system for construction engineering. This paper introduced the construction principle of the system and its application in the rigid and flexible sliding mode platform.
