| Abstract: | This paper introduced the software of auto-polar coordinate real time difference monitoring system, which is based on the full automatic control station. The principle and precision of difference measurement in the system has been discussed.The system may be used in automatic monitoring system for deformation of sloping body, bridge, dam. Multi-positions surveying could be finished within short time. The following could be realized: the correction of real time difference measurement of atmosphere refraction on measurement of distance, the angle for distortion point under the conditions without measuring weather element under simplifying equipment collocates of the system by using base point stability and the known information of benchmark net.The practical application indicates that the making up of monitoring system is rational with high degree and measurement precision could reach sub-millimeter. |
