Description
Technical Field
The invention relates to the technical field of detection, in particular to an inclination detection device.
Background
Many precision instruments are required to be kept horizontal during measurement, and when the instrument is inclined, the measurement result of the instrument is greatly influenced. The GNSS observation principle is that a GNSS reference station is used as a stationary point, and displacement monitoring is carried out by receiving satellite signals simultaneously with a measuring point, so that whether the measuring point displaces relative to the GNSS reference station or not is obtained. If no displacement occurs in the GNSS reference station, the corresponding displacement measurement can be carried out by directly taking the GNSS reference station in the survey area as a stationary point; if the GNSS reference station generates displacement, the displacement is corrected through the data measured by the GNSS reference station and the national or local reference station, the corrected coordinates of the GNSS reference station in the measuring area are used as fixed points, then satellite signals are synchronously received with the measuring points and are subjected to differential processing, so that the corrected coordinates of the measuring points are obtained, and whether the measuring points generate displacement or not is known.
According to the measurement principle, the position of the GNSS reference station needs to be kept fixed in the measurement process, otherwise, the measurement result of displacement of the measuring point can be greatly influenced, and therefore, a worker needs to detect and calibrate the position of the GNSS reference station in real time.
Because the GNSS reference station is generally arranged outdoors, the GNSS reference station may be affected by strong wind and strong rain of the external environment, so that the position of the GNSS reference station is shifted in the measurement process, the measurement result of the reference station on the measurement point is affected to a certain extent, and the worker cannot observe the inclination state of the GNSS reference station easily with naked eyes and cannot quickly correct the position of the GNSS reference station.
In view of the above, there is a need for an inclination detecting device to solve the problems in the prior art.
