高层建筑物变形监测的GPS多天线技术

分析了高层建筑物产生变形的原因和监测的基本方法，由此提出了利用GPS进行变形监测的方法。针对GPS变形监测系统成本高的问题，文中研究了GPS多天线技术，实现了一机对多点的监测。基于PC104在Visual C＋＋ 6．0开发平台下实现了多天线微波开关的控制、与GPS接收机的通信以及GPS信息的RINEX标准格式转化。实验表明，该技术对GPS测量精度几乎没有影响，能够有效应用于高层建筑物的变形监测。

Deformation monitoring of high-rising buidings based on multi-antenna GPS

The reasons and the monitoring methods of the high-rising buiding＇s deformation are arialyzed. The GPS multi-antenna technology aimed to the high cost of the large-scale GPS deformation monitoring project is studied. With this technique, one GPS receiver can monitor muhipoints. The software of GPS multiantenna data acquisition and control system（GMS） using the Visual C ＋ ＋ 6.0 based on PC104 is designed. The experiments indicate that GMS has almost no influence on the measurement accuracy of GPS and can be used to monitor the deformation of the high-rising buildings effectively.
