局域高程电子测量方法

摘要

工程施工过程中高程测量工作极其重要且工作量大,传统的水准测量、 三角高程测量、GPS高程测量从作业环境、 资源投入及精度控制方面均存在各自的不足.局域高程电子测量方法可实现对待测点放置手持测量器、 通过接受区域内基站发出的电磁波信号、 利用空间三角计算便可求得待测点高程数值,从而实现了高程测量的快捷与精准.%In the process of construction, the elevation measurement work is very important and the workload is large.The traditional level measurement, triangular elevation measurement and GPS elevation measurement have their own deficiencies in operating environment, resource input and precision control. The paper indicates a method to obtain the elevation value by placing a handheld measuring device on the test point to accept the electromagnetic wave signal issued by the regional base station and calculate with spatial triangulation.The research and development of this technology can achieve the elevation measurement fast and accurate.
