数字控制地形仪是用电子计算机进行控制以测量河工、水工或港工模型地形高程点的仪器。它的研究和使用,在我国大约只有十多年的历史,在水利部门应用的实例不多,有的只是一般的点位控制,即只控制定位点的最终位置,不控制点与点之间的运动轨迹。用数字控制技术进行轨迹运动的连续自动控制过程,在 Digitally Controlled Topographs are instruments that are controlled by a computer to measure the elevation points of a river, hydraulic, or harbor model. Its research and use are only about ten years old in our country. There are not many examples applied in the water conservancy department. Some are just ordinary point control, that is, only control the final position of the anchorage point, and do not control the point-to-point Motion track. Using digital control technology for continuous trajectory motion control process
