目前,水利施工工程中测绘过程的定位措施在测量管理设计方面还存在一定的问题。鉴于此,本文提出测绘过程的优化定位技术,并将其应用到长沙水利施工工程的测绘过程中。根据新技术,在基准站安置1台GPS接收机,并通过无线电传输设备,将施工现场数据实时发送给流动站,流动站接收数据后,实时计算出最优的节点数量和网络组成,并以最小计算代价计算三维坐标,以此为水利工作人员提供精确的样本和准确的数据。仿真试验表明,以长沙水利施工工程中的测绘数据为例,优化定位技术能够有效合理地对水利工程测绘过程进行优化,不仅减少了测绘的工作量,还在一定程度上提高了水利工程的测绘精度,具有高精度、高效率、多功能、操作简便、应用广泛等特点,进而促进了水利工程测绘过程中定位技术的发展。

At present, there are still some problems existing in the design aspect of the measurement management in the positioning measures adopted in water conservancy construction's surveying and mapping process. In view of this, the paper puts forward a kind of optimal positioning technology in surveying and mapping process, and applies it to the surveying and mapping process of water conservancy's construction works in Changsha city. According to the new technology, put one GPS receiver in the base station, and by radio transmission equipment, sent the real-time data of construction site to the moving station, after receiving the data, the moving station will work out the optimal number of nodes and the net? Work composition, and with the minimum computing cost, it will calculate the 3-D coordinates, hereby to provide precise samples and accurate data for the staff of water conservancy project. Taking the surveying and mapping data in water conservancy construction works in Changsha city as the example, the simulation test shows that the optimal positioning technology can effectively optimize the surveying and mapping process of water conservancy project, by doing so it not only reduces the work of surveying and mapping, but also improves the accuracy of surveying and mapping of water conservancy project, thus having features like high precision, high efficiency, multi-function, simple operation, as well as wide application and etc., therefore, it can promote the development of positioning technology in the surveying and mapping process of water conservancy projects.
