[0032] As mentioned above, the prior art has the following technical problems. In order to solve the technical problems in the prior art, namely, the traditional total station-based measurement system is expensive and complicated to operate, the inventor of the present disclosure innovatively thinks of using a sweeper to replace it, which can not only achieve the purpose of reducing the cost of the measurement system, but also achieve the transition dependence on operators and simplify the measurement process. Specifically, the present disclosure proposes a measurement system for measuring slope and a measurement method for measuring slope. In summary, the measuring system for measuring the slope proposed in accordance with the present disclosure includes: a leveling instrument, which is set at a first position; a distance measuring detector, which is set at a second position and a third position of the slope to be measured, wherein when the distance measuring detector is at the second position, the first distance between the leveling instrument and the distance measuring detector and the first height of the distance measuring detector are determined, and wherein when the distance measuring detector is at the third position, the second distance between the leveling instrument and the distance measuring detector and the second height of the distance measuring detector are determined, wherein 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. With the aid of the measuring system proposed in accordance with the present disclosure, the combination of the leveling instrument and the distance measuring detector can replace the traditional total station, which reduces the cost of the equipment for measuring the slope on the one hand, and can determine the slope of a slope to be measured in a simple manner on the other hand. In addition, the measuring method for measuring the slope proposed in accordance with the present disclosure includes: using a leveling instrument disposed at a first position to emit a horizontal laser; using a distance measuring detector disposed at the second position to determine 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 disposed at the third position to determine a second distance between the leveling instrument and the distance measuring detector and a second height of the distance measuring detector; 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. With the aid of the measuring method for measuring the slope proposed in accordance with the present disclosure, a combination of a leveling instrument and a distance measuring detector can be used to replace a traditional total station, which reduces the cost of the equipment for measuring the slope on the one hand, and can determine the slope of a slope to be measured in a simple manner on the other hand.

[0033] The following will be combined Figure 1 and Figure 2 The measuring system for measuring the slope and the measuring method for measuring the slope disclosed in the present disclosure are described below. Figure 1 FIG. 1 shows a connection diagram of a measuring system 100 for measuring a slope according to an embodiment of the present disclosure. Figure 2A method flow chart of a measuring method 200 for measuring a slope according to an embodiment of the present disclosure is shown.

[0034] from Figure 1 It can be seen that the measuring system 100 for measuring slope according to the present disclosure mainly includes two parts, namely, the leveling instrument 110 and the distance measuring detector 120. The leveling instrument 110 is set at a first position (e.g. Figure 1 The distance measuring detector 120 is set at the second position and the third position of the inclined surface to be measured (for example Figure 1 The present invention relates to a method for measuring the slope of the inclined plane to be measured, wherein the first distance L1 between the leveling instrument 110 and the ranging detector 120 and the first height H1 of the ranging detector are determined when the ranging detector 120 is in the second position, and wherein the second distance L2 between the leveling instrument 110 and the ranging detector 120 and the second height H2 of the ranging detector are determined when the ranging detector 120 is in the third position, wherein the slope of the inclined plane 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 measuring system 100 proposed according to the present disclosure, the combination of the leveling instrument 110 and the ranging detector 120 can replace the traditional total station, which reduces the cost of the equipment for measuring the slope on the one hand, and can determine the slope of a slope to be measured in a simple manner on the other hand. Here, a wireless communication connection 130 can be established between the leveling instrument 110 and the distance measuring detector 120. The wireless communication connection 130 can be a network connection based on a WiFi protocol, or a network connection based on other bus protocols such as RS232, ZigBee, Bluetooth, ProfiBus, etc., as long as the communication connection between the leveling instrument 110 and the distance measuring detector 120 can be achieved. In this way, when the measurement system 100 according to the present disclosure 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 distance measuring 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 inclined plane, those skilled in the art should understand that the bottom here is only exemplary and not restrictive, and it is also feasible at other positions of the inclined plane.

[0035] In a technical solution according to an embodiment of the present disclosure, the first position, the second position and the third position are in a straight line. That is, the position of the leveling instrument 110 and the position of the distance measuring detector 120 are in a straight line. In this way, the accuracy of the slope of the inclined surface to be measured measured by the measuring system according to the present disclosure can be maximized.

[0036] Preferably, in a technical solution according to an embodiment of the present disclosure, the tangent value of the slope angle is equal to the height difference divided by the distance difference. In this way, the slope value of the inclined surface can be calculated more easily. That is, the slope value can be directly displayed through the software function tan(a)=height difference H / horizontal distance difference L.

[0037] More preferably, in a technical solution according to an embodiment of the present disclosure, the distance measuring detector includes a downward emitting laser head, and the laser head is configured to measure the distance between the distance measuring detector and the ground on which it is set. For example, when the distance measuring detector is at the second position, the height of the distance measuring detector is measured to be 0.8 meters by means of the downward emitting laser head; and when the distance measuring detector is at the third position, the height of the distance measuring detector is measured to be 0.3 meters by means of the downward emitting laser head, and the height difference between the second position and the third position is 08-0.3=0.5 meters. In this way, the height of the detector from the ground can be conveniently determined, and the height difference between the second position and the third position before and after the distance measuring detector can be determined accordingly, and the slope of the slope can be determined.

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

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

[0040] Preferably, in a technical solution according to an embodiment of the present disclosure, 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 the present disclosure proposes a measurement method for measuring a slope. Figure 2 FIG. 2 is a flow chart of a method 200 for measuring a slope according to an embodiment of the present disclosure. Figure 2 It can be seen that the measurement method 200 proposed according to the present disclosure includes at least the following four steps: first, in method step 210, a horizontal laser is emitted by a leveling instrument arranged at a first position; then, in method step 220, a first distance between the leveling instrument and the distance measuring detector and a first height of the distance measuring detector are determined by a distance measuring detector arranged at the second position; next, in method step 230, a second distance between the leveling instrument and the distance measuring detector and a second height of the distance measuring detector are determined by a distance measuring detector arranged at the third position; 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 measurement method for measuring the slope proposed according to the present disclosure, the combination of the leveling instrument 110 and the distance measuring detector 120 can replace the traditional total station, which reduces the cost of the equipment for measuring the slope on the one hand, and can determine the slope of a slope to be measured in a simple manner on the other hand.

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

[0043] More preferably, in a technical solution according to an embodiment of the present disclosure, the measuring method further comprises: using a downward emitting laser head included in the ranging detector to measure the distance between the ranging detector and the ground on which it is set. For example, when at the second position, the height of the ranging detector measured by the downward emitting laser head is 0.8 meters; and when at the third position, the height of the ranging detector measured by the downward emitting laser head is 0.3 meters, then the height difference between the second position and the third position is 08-0.3=0.5 meters. In this way, the height of the detector from the ground on which it is located can be conveniently determined, and the height difference between the second position and the third position on which the ranging detector is located can be determined accordingly, and the slope of the slope on which it is located can be determined.

[0044] In a technical solution according to an embodiment of the present disclosure, the first distance or the second distance is determined based on the centering function and the horizontal distance measuring function of the distance measuring detector. That is, the distance measuring 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 distance measuring detector 120 is measured at this height.

[0045] To sum up, in the technical solution according to the contents of the present disclosure, with the aid of the measuring system for measuring slope and the measuring method for measuring slope proposed according to the contents of the present disclosure, the traditional total station can be replaced by a combination of a leveling instrument and a ranging detector. This, on the one hand, reduces the cost of the equipment for measuring the slope, and on the other hand, it can determine the slope of a slope to be measured in a simple way.
