Detailed Description
The foregoing and other features and advantages of the invention will be apparent from the following, more particular, description of the invention, as illustrated in the accompanying drawings, in which embodiments described are merely some, but not all embodiments of the invention.
Referring to fig. 1, a view of one embodiment of a laser ranging matrix is shown. Two buildings to be tested are shown in the figure, and a laser emission terminal 1 is arranged at four corners of each building to be tested; a laser receiving terminal 2 is also shown, which laser receiving terminal 2 is located at a reference position where the geology is hard. The reference location may be selected because a stiffer geology location is more difficult to settle relative to other locations. In fact, during normal subsidence of the earth's surface, it is in a state of subsidence relative to the reference position during this process, since the degree of subsidence of the two buildings to be tested is greater. The figure also shows the state in which the laser light emitting terminals 1 on the outside of two buildings under test emit laser light to the laser light receiving terminals 2, and the arrow in the figure is the direction of the laser light.
In the normal subsidence process of the ground surface, the position of the projection point on the laser receiving terminal 2 can be changed, and whether the subsidence and the subsidence height can be determined in the process of changing the position of the projection point; finally, displaying on a locally connected display screen or a network connected display screen; compared with the traditional Beidou satellite technology, the laser ranging method has better precision and can reach millimeter level.
The laser receiving terminal 2 in the figure is in one-to-many relation with the laser emitting terminal 1 on the building under test, and since the laser emitting terminal 1 is connected with the server. The laser emitting terminals 1 on the respective buildings to be tested can be controlled to emit laser light in turn by a control instruction from the server, and the laser emitting terminals 1 on the respective buildings to be tested share one laser receiving terminal 2. In practice, only one laser receiving terminal 2 needs to be installed in one section, and the laser receiving terminal 2 is shaped like a tall tower for receiving laser light from each building under test in this section; under the control of the control instruction, the laser emitting terminals 1 on each building to be tested alternately emit laser light to the laser receiving terminals 2, and if one building to be tested is settled, the projection point position of the laser light emitted from the building to be tested is correspondingly changed.
Referring to fig. 2, a view of one embodiment of a laser ranging matrix is shown. The figure shows that the measured building is at a distance of 100m from the reference location, in practice the measured building may be more than 100m from the reference location. In addition, the positions of 4 laser emitting terminals 1 on the building to be tested are also shown in the figure, and 4 laser emitting terminals 1 are uniformly provided on the outside of the building to be tested. Of course, if there are some buildings with large volumes, as shown in fig. 3, several laser emitting terminals 1 may be disposed along the length direction of the building under test, while several laser emitting terminals 1 are disposed along the width direction of the building under test.
In both cases, there is a case where a part of the laser light emitting terminal 1 is blocked by a building, so that it cannot directly emit laser light to the laser light receiving terminal 2. In the present embodiment, however, the mirror 3 is provided as a medium for reflection. The mirror surface 3 is fixed on the outer side of a building, an angle for laser reflection is provided, and the laser emission terminal 1 facing away from the laser receiving terminal 2 indirectly emits laser to the laser receiving terminal 2 through reflection of the mirror surface 3; and the laser light emitting terminal 1 facing the laser light receiving terminal 2 emits laser light directly to the laser light receiving terminal 2.
In the present embodiment, since the laser light receiving terminal 2 receives laser light at different positions on the building, it is possible to determine how the building is settled down according to the variation of the projection points of the laser light at the different positions. For example, the left side of the building is settled to a larger extent in the early stage, but the right side of the building is kept up to the extent of the later stage, so that the whole building is kept in a vertically settled state. Therefore, the scene of building settlement can be restored according to the projection point position change data of the lasers at different positions.
Referring to fig. 1 and 2, the laser light receiving terminal 2 includes an upright ring-shaped screen for receiving laser light from each building under test. In practice, the laser light receiving terminal 2 is to receive the laser light of each building under test in one zone, so that the ring screen is advantageous for practical use.
In one embodiment, the laser receiving terminal 2 generates a position coordinate curve according to the position changes of the plurality of projection points in a unit time, and transmits the position coordinate curve to the mobile terminal; the unit time length of the earlier stage of the position coordinate curve is larger than that of the later stage.
In this embodiment, the sedimentation state of the building can be visually seen from this position coordinate curve. For example, the unit time length can be increased appropriately for the earlier data, and the corresponding position coordinate curves show the sedimentation state of the earlier building, which is clear. For recent data, the unit time length can be properly reduced, and the corresponding position coordinate curve represents the sedimentation state of the recent building, so that the method is suitable for data analysis.
In one embodiment, the laser receiving terminal 2 is connected to a server and is used to upload data of the sedimentation height of the building under test to the server.
In this embodiment, the user may download the data directly from the cloud to obtain the settlement status of the building.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present invention, and are not to be construed as limiting the scope of the invention. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present invention are intended to be included in the scope of the present invention.
