| 摘 要： | GPS激光测距动态定位系统是激光测距与GPS定位系统的集成应用,通过测设测点坐标与目标点斜距信息,运用空间测边交会方法进行定位。本文阐述了GPS激光测距系统的定位模式,数据管理及在数据实时处理中的应用。GPS激光测距动态定位系统所有数据都是通过串口发送到计算机。合理、高效地从接收到的数据中分离出各个模块的数据是实现系统稳定工作的关键。本文提出基于内部循环结构对多串口的数据分离和同步数据提取算法,实现了多通道串口数据管理及实时处理,软件运行的结果显示该算法高效地为主动定位系统的状态监视和定位解算提供了正确的数据。

| Abstract: | GPS laser ranging dynamic positioning system is an integrated application of laser ranging module and GPS position system.It uses distance difference between two ranges from survey point to target to resolve the target's position.The data are sent to workstation through a serial port.The data from every channel are mixed with each other.It is the core part of the control center's work and the base for further process to separate every channel's data efficiently and reasonably.An efficient method to separate every channel's data was given in the paper.Test results showed that it worked well. |
