Technical Field

The utility model relates to the field of hydraulic engineering safety monitoring, in particular to a coaxial observation structure of a GNSS reference station and a surveying robot reference station, in particular to a coaxial observation reinforced concrete column structure of the GNSS reference station and the surveying robot reference station, which is a concrete structure capable of ensuring that the GNSS reference station and the surveying robot reference station are in coaxial positions.

Background

In the field of hydraulic and hydroelectric engineering safety monitoring automation, the surface deformation automatic monitoring generally adopts a mode of combined operation of a GNSS reference station and a measuring robot reference station. The GNSS reference station consists of a GNSS antenna, a receiver and an observation pillar, and the observation principle is that the position of the GNSS antenna is obtained through global satellite positioning; the principle of the measuring robot reference station is that the relative position of a monitoring point is calculated by measuring the side length and the angle between the measuring robot and the monitoring point. The principle of the automatic measurement of the surface deformation is that a measuring robot is used as a fixed point, and the relative variation of the monitoring point is obtained by observing the position of the monitoring point. In fact, the position of the reference station of the surveying robot is only relatively stable, not an absolute "motionless point", at which time the position of the surveying robot needs to be corrected by a GNSS embedded in the same position as the surveying robot. After all, GNSS datum points and measuring robots belong to 2 different measuring instruments, no instrument integrating the GNSS and the measuring robot is developed in the market at present, and the GNSS is buried outdoors to ensure that the GNSS receives satellite signals, so that the observation precision of the GNSS is ensured; the measurement robot needs to be protected by an observation room and can only be buried indoors with a protection device, so that the problem that how to ensure that the displacement change of the GNSS reference point can truly reflect the change of the measurement robot needs to be solved at present.

According to the existing application number 201621228396, the patent name "manufacturing method of integrated protection house structure of GNSS reference station and surveying robot reference station", the GNSS reference station and the surveying robot reference station are buried in an observation house on the same foundation, the GNSS reference station is lifted out of the observation house through a concrete column, the surveying robot is buried in the observation house through another concrete column, so that the GNSS reference station and the surveying robot reference station synchronously change, but the GNSS reference station and the surveying robot reference station are buried above different concrete columns, and when the observation house foundation is unevenly settled, errors exist in the surveying robot reference station corrected through the GNSS reference station.

Therefore, it is necessary to develop a structure for ensuring that the displacement change of the GNSS reference point can truly reflect the change of the measurement robot.
