Description

Technical Field

[0001] The invention relates to the technical field of land surveying, in particular to a land surveying device for construction. Background Art

[0002] In construction engineering activities, in order to measure the topography of the land, engineering technicians often use total stations for measurement. Total stations are a high-tech measuring instrument that integrates optics, mechanics, and electronics. They are surveying and mapping instrument systems that integrate horizontal angle, vertical angle, distance, and height difference measurement functions. The use of total stations can very conveniently carry out land surveying tasks in construction activities; total stations can automatically measure angles and distances when in use, and can transmit measurement data to corresponding data collectors according to certain procedures and formats. Total stations have a high degree of automation, multiple functions, and good accuracy. By configuring appropriate interfaces, the measurement data collected outdoors can be directly entered into a computer for data processing or into an automated mapping system. However, total stations under the existing technology still have the following shortcomings.

[0003] When traditional land surveying equipment is actually used, it is necessary to first install a survey bracket, then level the survey bracket, and then install the survey instrument to perform surveying operations to ensure the accuracy of the survey. During actual surveying and mapping operations, the device may tilt due to operator interference. Traditional equipment does not have an auxiliary leveling device. If the instrument is found to be offset during the survey, it is generally necessary to recalibrate and level the bracket, which will take too long. At the same time, traditional surveying equipment does not have an alarm device. If the tilt is not discovered and leveled in time, it will affect the accuracy of the survey data. Summary of the invention
