Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to a positioning displacement measuring device for surveying. Background Art

[0002] During underground surface survey activities, for large equipment placed on the ground, buildings constructed to assist in survey activities, and the main structures of structures, corresponding markers must be set up and measurement and monitoring equipment must be used to measure and monitor displacement, so as to promptly detect whether buildings, structures or large ground equipment have shifted or tilted due to changes in the foundation of the strata, which would have an adverse effect on the survey activities.

[0003] Underground surface survey activities are often accompanied by frequent drilling construction of large equipment. Therefore, large equipment placed on the ground, buildings constructed to assist in survey activities, and main structures of structures often experience large displacement changes. This displacement change can be measured by existing GPS equipment. By comparing the positioning data of the equipment and structures after displacement with the original positioning data, the horizontal displacement and elevation displacement changes can be detected more accurately, and the measurement is very convenient and fast. However, the current GPS mobile station cannot locate and mark the measuring points on the survey equipment and structures during measurement. Other tools and methods are needed to set up markers. However, when measuring, people often forget to carry marking tools or it is inconvenient to carry marking tools, which makes measurement inconvenient.

[0004] Therefore, in order to address the problem that it is impossible to mark the measuring points when using GPS measurement and survey equipment and the displacement of structures, and it is inconvenient to use other tools, a GPS measurement device with an integrated marking tool can be designed to improve the convenience of survey and measurement.
