摘要
传统工程测量领域中多使用离线作业方式,通过纸质表单分配测量任务和记录测量成果,直接造成了管理难度高、作业效率低的局面。基于全球导航卫星定位系统(GNSS),与互联网及无线通信技术相结合,使用B/S架构开发出一套在线工程测量系统。在本地服务端使用实时相对定位技术获取流动站空间坐标,并内置转换算法模块构建数据链,实现在多坐标系实时数据下在线完成施工放样任务。该系统实时性强,成本低,精度高,易于管理,已在某高铁项目的实地施工测量中通过测试。
In the field of traditional engineering measurement, offline operations are often used. Allocating tasks and recording measurement results through paper forms directly results in difficult management and low efficiency. Based on the global navigation satellite positioning system（ GNSS）, combined with the Internet and wireless communication technology, a set of online engineering measurement system was developed by using B/S architecture. The real-time relative positioning technology was used to obtain the spatial coordinates of mobile station in local server, and the built-in conversion algorithm modules was used to form the data link, so the goal of on-line completing lofting tasks in construction with the real-time data of multi-coordinate system was achieved. With performances of strong real-time, low cost, high accuracy, easy management, this system has passed the spot test in a high-speed rail project.
