Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, and more specifically to a measurement system for measuring slope. Background Technology

[0002] Traditional engineering slope measurement involves using a total station and a target (such as a ruler). The total station's angle measurement function is used to measure the height angle difference and slope between different targets, thus determining the slope at two relative heights. This method requires at least two people to operate, and total stations are expensive, resulting in high equipment costs and increased labor costs for the project.

[0003] Therefore, in the field of surveying and mapping, there is a need to replace total stations, whether from the perspective of reducing costs or simplifying operations. Utility Model Content

[0032] As mentioned above, the existing technology has the following technical problems. To solve these problems, namely, that traditional total station-based measurement systems are expensive and complex to operate, the inventors of this utility model innovatively conceived of using a leveling instrument to replace them. This not only reduces the cost of the measurement system but also reduces reliance on operators and simplifies the measurement process. Specifically, this utility model proposes a measurement system and a method for measuring slope. In summary, the slope measurement system proposed according to this utility model includes: a leveling instrument, which is set at a first position; and a distance measuring detector, which is set at a second and a third position on the slope to be measured. When the distance measuring detector is at the second position, a first distance between the leveling instrument and the distance measuring detector and a first height of the distance measuring detector are determined. When the distance measuring detector is at the third position, a second distance between the leveling instrument and the distance measuring detector and a second height of the distance measuring detector are determined. The slope of the slope to be measured is determined based on the height difference between the first height and the second height and the distance difference between the first distance and the second distance. By using the measurement system proposed according to this utility model, a combination of a leveling instrument and a distance measuring detector can replace a traditional total station. This reduces the cost of slope measurement equipment and allows for the simple determination of the slope of a slope to be measured. Furthermore, the slope measurement method proposed according to this utility model includes: emitting a horizontal laser using a leveling instrument positioned at a first location; determining a first distance between the leveling instrument and the distance measuring detector, and a first height of the distance measuring detector, using a distance measuring detector positioned at a second location; determining a second distance between the leveling instrument and the distance measuring detector, and a second height of the distance measuring detector, using a distance measuring detector positioned at a third location; and determining the slope of the slope to be measured based on the height difference between the first height and the second height, and the distance difference between the first distance and the second distance. By using the slope measurement method proposed according to this utility model, a combination of a leveling instrument and a distance measuring detector can replace a traditional total station. This reduces the cost of the slope measurement equipment and allows for a simple determination of the slope of a slope to be measured.

[0033] The following will combine Figure 1 and Figure 2 This invention describes a measurement system and method for measuring slope according to the present invention. Figure 1 A connection diagram of a measurement system 100 for measuring slope according to an embodiment of the present invention is shown, while Figure 2A flowchart of a method 200 for measuring slope according to an embodiment of the present invention is shown.

[0034] from Figure 1 As can be seen, the slope measurement system 100 proposed according to this utility model mainly includes two parts: a leveling instrument 110 and a distance measuring detector 120. The leveling instrument 110 is set in a first position (e.g., Figure 1 The left-hand position shown in the diagram), while the ranging detector 120 is set at the second and third positions on the inclined plane to be measured (e.g., the left-hand position). Figure 1 The diagram shows the positions of the bottom and middle of the slope. When the distance measuring detector 120 is in the second position, a first distance L1 between the leveling instrument 110 and the distance measuring detector 120, and a first height H1 of the distance measuring detector are determined. When the distance measuring detector 120 is in the third position, a second distance L2 between the leveling instrument 110 and the distance measuring detector 120, and a second height H2 of the distance measuring detector are determined. The slope of the slope to be measured is determined based on the height difference H between the first height H1 and the second height H2, and the distance difference L between the first distance L1 and the second distance L2. By means of the measurement system 100 proposed according to this invention, a combination of the leveling instrument 110 and the distance measuring detector 120 can replace a traditional total station. This reduces the cost of the equipment for measuring slope and allows for the simple determination of the slope of a slope to be measured. Here, a wireless communication connection 130 can be established between the leveling instrument 110 and the ranging detector 120. This wireless communication connection 130 can be, for example, a network connection based on the WiFi protocol, or a network connection based on other bus protocols such as RS232, ZigBee, Bluetooth, or ProfiBus, as long as it enables communication between the leveling instrument 110 and the ranging detector 120. In this way, when the measurement system 100 according to this utility model is used, the operator of the measurement system 100 does not need to manually exchange information or data between the leveling instrument 110 and the ranging detector 120, but can exchange data through the wireless communication connection 130. Furthermore, although the second position shown in the figure is located at the bottom of the slope, those skilled in the art should understand that the bottom here is merely exemplary and not restrictive, and it is also feasible at other positions on the slope.

[0035] In one embodiment of the present invention, the first position, the second position, and the third position are on a straight line. That is, the position of the leveling instrument 110 and the position of the ranging detector 120 are on a straight line. This maximizes the accuracy of the slope of the inclined plane measured by the measurement system according to the present invention.

[0036] Preferably, in one embodiment of the present invention, the tangent of the slope angle is equal to the height difference divided by the distance difference. This allows for a relatively simple calculation of the slope value. In other words, the slope value can be directly displayed using the software function tan(a) = height difference H / horizontal distance difference L.

[0037] More preferably, in one embodiment of the present invention, the ranging detector includes a downward-emitting laser head configured to measure the distance between the ranging detector and the ground. For example, at the second position, the downward-emitting laser head measures the distance of the ranging detector to 0.8 meters; and at the third position, the downward-emitting laser head measures the distance to 0.3 meters. The height difference between the second and third positions is 0.8 - 0.3 = 0.5 meters. This method allows for convenient determination of the detector's height above the ground, and consequently, the height difference between the second and third positions, and thus the slope of the incline.

[0038] Optionally, in one embodiment of the present invention, the first distance or the second distance is determined based on the centering function and horizontal ranging function of the ranging detector. That is, the ranging detector is first adjusted to the same absolute height using the centering function, i.e., the height of the scanning plane of the laser emitted by the level, and then the distance between the leveling instrument 110 and the ranging detector 120 is measured at that height. For example, the distance is 5 meters at the second position, and 10 meters at the third position. At this time, for a slope, the distance difference is 5 meters, and as mentioned above, the corresponding height difference may be 0.5 meters. Therefore, the tangent of the angle corresponding to this slope is 0.5 / 5 = 0.1, and the angle corresponding to the slope can be calculated accordingly. Preferably, in a technical solution according to an embodiment of the present invention, determining the first distance L1 between the leveling instrument 110 and the leveling detector 120 when the leveling detector 120 is in the second position further includes: emitting a vertical laser beam rotating in a vertical plane at a first rotational speed using the first laser emitting part of the leveling instrument 110; calculating the time difference between the vertical laser beam passing through the first optical detection component and the second optical detection component using a first optical detection component and a second optical detection component that are at least partially located in the same vertical plane, wherein the distance between the two optical detection components is a first spacing; and calculating the first distance L1 between the leveling instrument and the leveling detector based on the first rotational speed, the first spacing, and the time difference.

[0039] More preferably, in a technical solution according to an embodiment of the present invention, determining the second distance between the leveling instrument 110 and the range measuring detector 120 when the range measuring detector 120 is in the third position further includes: emitting a vertical laser beam rotating in a vertical plane at a first rotational speed using the first laser emitting part of the leveling instrument 110; calculating the time difference between the vertical laser beam passing through the first optical detection component and the second optical detection component using a first optical detection component and a second optical detection component that are at least partially located in the same vertical plane, wherein the distance between the two optical detection components 120 is a first spacing; and calculating the second distance L2 between the leveling instrument and the range measuring detector based on the first rotational speed, the first spacing, and the time difference.

[0040] Preferably, in one embodiment of the present invention, the first optical detection component and the second optical detection component on the ranging detector 120 are vertically arranged by means of a universal joint, an electronic bubble, a structural bubble, or a horizontally arranged bearing.

[0041] Furthermore, a second aspect of this invention provides a method for measuring slope. Figure 2 A flowchart of a method 200 for measuring slope according to an embodiment of the present invention is shown. Figure 2 As can be seen from this, the measurement method 200 proposed according to this utility model includes at least the following four steps: First, in method step 210, a leveling instrument set at a first position emits a horizontal laser; then, in method step 220, a distance measuring detector set at a second position determines a first distance between the leveling instrument and the distance measuring detector, as well as a first height of the distance measuring detector; next, in method step 230, a distance measuring detector set at a third position determines a second distance between the leveling instrument and the distance measuring detector, as well as a second height of the distance measuring detector; and finally, in method step 240, the slope of the slope to be measured is determined based on the height difference between the first height and the second height, and the distance difference between the first distance and the second distance. By means of the slope measurement method proposed according to this utility model, a combination of a leveling instrument 110 and a distance measuring detector 120 can replace a traditional total station. This reduces the cost of the equipment for measuring slope and allows for the simple determination of the slope of a slope to be measured.

[0042] Preferably, in one embodiment of the present invention, the first position, the second position, and the third position are on a straight line. Preferably, in one embodiment of the present invention, the tangent of the slope angle is equal to the height difference divided by the distance difference.

[0043] More preferably, in one embodiment of the present invention, the measurement method further includes: measuring the distance between the ranging detector and the ground using a downward-emitting laser head included in the ranging detector. For example, at the second position, the height of the ranging detector is measured to be 0.8 meters using the downward-emitting laser head; and at the third position, the height of the ranging detector is measured to be 0.3 meters using the downward-emitting laser head. The height difference between the second and third positions is 0.8 - 0.3 = 0.5 meters. In this way, the height of the detector above the ground can be easily determined, and the height difference between the second and third positions of the ranging detector can be determined, thereby determining the slope of the slope.

[0044] In one embodiment of the present invention, the first distance or the second distance is determined based on the centering function and the horizontal ranging function of the ranging detector. That is, the ranging detector is first adjusted to the same absolute height, i.e., the height of the scanning plane of the laser emitted by the level, by means of the centering function, and then the distance between the leveling instrument 110 and the ranging detector 120 is measured at that height.

[0045] In summary, in the technical solution of this utility model, by means of the measurement system and method for measuring slope proposed by this utility model, the combination of a leveling instrument and a distance measuring detector can replace the traditional total station. On the one hand, this reduces the cost of the equipment for measuring slope, and on the other hand, it can determine the slope of a slope to be measured in a simple way.
