Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 Shown, a kind of non-prism subsidence surface monitoring method, comprises the following steps:

[0032] 1) After installing the automatic total station 1, turn on the power supply 3, select 4 regional control points, connect the adjacent points in pairs, determine the number of equally divided points on the long side and short side, and obtain the coordinates of the station and 4 Region control point coordinates, if figure 2 shown;

[0033] 2) By calculating the coordinates of the equal points of the long side and the short side, respectively calculate the coordinate values ​​of the points to be measured in the control area;

[0034] 3) Obtain the horizontal direction angle and the vertical angle of the automatic total station 1 according to the coordinates of each point and the coordinates of the station;

Abstract

The invention relates to a prism-free surface settlement level monitoring method, which comprises the following steps: 1) when an automatic total station is installed, selecting four regional control points; 2) respectively calculating coordinates of points to be measured in control regions by calculating coordinates of evenly dividing points of long sides and short sides; 3) obtaining the horizontal direction angle and the vertical angle of the automatic total station according to the coordinates of each point and the coordinates of a station observation point; 4) rotating the collimation axis of the automatic total station to the angle through an automotive motor, measuring the distances S from the station observation point and each grid point and the vertical angle alpha, and obtaining the height difference H between the station observation point and each grid point based on the formula H = D . tg(alpha); 5) storing the obtained data on the automatic total station and transmitting the data to an upper computer by the automatic total station through a wireless transmission module; and 6) displaying final results on a display screen after data processing of the upper computer. Compared with the prior art, the invention has the advantages that the settlement of a hard flat surface on which a round prism cannot be installed can be monitored.

Description

technical field [0001] The invention relates to a method for monitoring a surface subsidence surface, in particular to a method for monitoring a surface subsidence without a prism. Background technique [0002] At present, the application of automatic total station usually uses prism, and in the monitoring of land surface subsidence, almost no prism-free measurement is carried out. However, in some special monitoring areas, such as airport runways, taxiways, expressways, etc., where the line of sight can pass but cannot be monitored using prisms, a second-best monitoring method is still required. Even if a prism-free automatic total station is used, it is more for single-point measurement when a prism cannot be placed. Since the ranging accuracy of the prism-free automatic total station is lower than that of the circular prism, and the prism-free ranging has higher requirements on meteorological conditions and surrounding environments, the value of a single measuring point ...
