Abstract:

High speed railway CPⅢ plane control network requires high precision and the measurement task is complex,usually using high precision measuring robot forautomatic measurement.This paper studies deeply the network scheme and the measuring method of the CPⅢ plane control network,and proposes an automatic learning method of adjacent station public CPⅢ control points,and uses the C# language to write the program for CPⅢ data acquisition software.Through practical engineering verification,this method can ensure that the robot can accurately locate the target point and improve the efficiency of the field process.

Key words: CPⅢ plane control network, plane coordinate transformation, triangulation height measurement, automatic learning
