Description

Technical Field

[0001] The invention relates to the technical field of automatic land measurement, in particular to a soil slope measuring device used in land engineering. Background Art

[0002] Land surveying is an essential surveying and mapping process in the process of land reserve and land construction. In the process of land surveying, due to the unevenness of the land, there will be earth slopes and flat bottoms. For the slope measurement of the earth slope, the existing simple land slope measuring instrument is placed directly on the slope surface of the earth slope, and the slope angle of the slope surface is measured by the land slope measuring instrument. However, because the land surface is mostly irregular and the slope on the broken surface is not completely consistent, direct measurement on the slope surface cannot effectively and accurately reflect the slope of the earth slope, which increases the difficulty of slope measurement; in addition, in the process of measuring with the land slope measuring instrument, the surveyor needs to hold the instrument and place it on the ground, and then manually adjust the level to obtain the slope. This requires the surveyor to constantly stand up and squat, which will increase the labor intensity of the surveyor. At the same time, the manual adjustment of the level will result in the level not being accurately adjusted to a horizontal state, which will also lead to the accuracy of the slope measurement, and thus affect the surveyor's measurement efficiency.

[0003] In order to solve the above problems, the technical personnel in this field proposed an invention patent of a land slope measuring device for engineering exploration, and its publication number is: CN112268544A; the patent is to set a receiving chamber inside the box body, and a slope measuring swinging piece can be rotatably set in the receiving chamber, and the slope measuring swinging piece is provided with a slope scale and an arc-shaped plug-in positioning groove, and an arc-shaped swing limiting groove is opened on the rear wall of the receiving chamber; a vertical fixed pointer is fixedly connected to the rear wall of the receiving chamber, and the needle end of the vertical fixed pointer points to the slope scale; a swing limiting piece is fixedly connected to the bottom end of the slope measuring swinging piece, and the bottom end of the swing limiting piece is in rolling contact with the arc-shaped swing limiting groove; a telescopic plug-in positioning rod is passed through the rear wall of the box body and plugged and fixed with the arc-shaped plug-in positioning groove. The patent uses the above structure to reduce the swing time of the slope measuring swinging piece, so that it can quickly reach stability, and can quickly position and fix the slope measuring swinging piece, thereby realizing fast measurement and high measurement efficiency.

[0004] However, the above patent only shortens the swing time of the swing member and improves the efficiency of slope measurement during the specific implementation process, but its measurement position is still located on the slope surface, that is, the above patent still cannot overcome the technical problems of inaccurate measurement results and great measurement difficulty caused by the irregular slope surface during the measurement process. Therefore, those skilled in the art need an automatic measurement device that can measure the slope of a soil slope as a whole. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and to design a soil slope gradient measuring device for land engineering.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is a soil slope slope measurement device for land engineering, comprising a target component 1, a target component 2, a drone measurement component and an intelligent terminal; The target component 1 is arranged at the top of the earth slope, and the target component 1 can transmit its own position data to the intelligent terminal; The target component 2 is arranged at the bottom of the earth slope, the position of the target component 2 corresponds to the position of the target component 1, and the target component 1 can transmit its own position data to the intelligent terminal; The drone measurement component can measure the distance between it and the target component 1 in the vertical direction, and the drone measurement component can also measure the distance between it and the target component 2 in the vertical direction; The intelligent terminal can receive the position data output by the target component 1 and the target component 2, and calculate the horizontal distance value between the target component 1 and the target component 2 using the received position data.

[0007] The drone measurement component can fly between the target component 2 and the target component 1 at the same horizontal height along a straight line at a constant speed.

[0008] The drone measurement component includes a drone and a placement rack. The drone can be placed on the placement rack. A rangefinder is installed on the lower surface of the drone. The rangefinder can measure the distance between it and the target component one or the target component two in the vertical direction. The rangefinder can transmit the measured distance value to the smart terminal.

[0014] The position of the drone can be adjusted by manual correction or image acquisition correction to ensure that the drone can hover directly above the baffle 1 or the baffle 2.

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-Figure 4 As shown; A soil slope measuring device for land engineering, comprising a target component 1, a target component 2, a drone measuring component and an intelligent terminal; The target component 1 is arranged on the top of the slope, the target component 1 can receive and reflect the vertical light beam, and the target component 1 can transmit its own position data to the intelligent terminal; Target component 2 is arranged at the bottom of the slope. The position of target component 2 corresponds to the position of target component 1. Target component 2 and target saddle 1 are both located in the same vertical plane. Target component 2 can receive and reflect light beams in the vertical direction. Target component 1 can transmit its own position data to the intelligent terminal. It should be noted that the target component 1 includes a bracket 3, a baffle 4 is installed on the upper end of the bracket 3, the baffle 4 is located in the horizontal plane and ensures that the rangefinder 9 can measure the distance between it and the baffle 4 in the vertical direction, and a positioning module 5 is installed on the bracket 3. The positioning module 5 implements wireless data interaction with the intelligent terminal, and the positioning module 5 can transmit its position data to the intelligent terminal; the target component 2 includes a bracket 2 6, a baffle 2 7 is installed on the upper end of the bracket 2 6, the baffle 2 7 is located in the horizontal plane and ensures that the rangefinder 9 can measure the distance between it and the baffle 2 7 in the vertical direction, and a positioning module 2 8 is installed on the bracket 2 6. The positioning module 2 8 implements wireless data interaction with the intelligent terminal, and the positioning module 2 8 can transmit its position data to the intelligent terminal. The position data is transmitted to the intelligent terminal; the bracket 1 3 is arranged at the top of the earth slope, and the bracket 2 6 is arranged at the bottom of the earth slope. The heights of the bracket 1 3 and the bracket 2 6 are the same, the distance between the baffle 1 4 and the top of the slope is equal to the distance between the baffle 2 7 and the bottom of the slope, the baffle 1 4 is parallel to the baffle 2 7, and the baffle 1 4 and the baffle 2 7 are both plates made of non-transparent materials, and the shape and size of the baffle 1 4 are the same as the shape and size of the baffle 2 7; wherein, the shape and size of the bracket 1 3 are the same as the shape and size of the bracket 2 6, the position of the positioning module 1 5 on the bracket 1 3 corresponds to the position of the positioning module 2 8 on the bracket 2 6, and when the positioning module 1 5 is located at the center of the bracket 1 3, the positioning module 2 8 is also located at the center of the bracket 2 6.

[0019] The drone measurement component can fly to the top of target component 1 or target component 2 under the remote control of the staff, and fly between the top of target component 1 and the top of target component 2 along a straight line at the same height. When the drone measurement component is located above target component 1, it can measure the distance value between it and target component 1 in the vertical direction. When the drone measurement component is located above target component 2, it can measure the distance value between it and target component 2 in the vertical direction. Among them, the drone 1 released by the drone measurement component flies to the top of target component 1 or target component 2 and completes the distance value measurement in the vertical direction, and then flies to the top of target component 2 or target component 1 at the same horizontal height along a straight line at a uniform speed and completes the distance value measurement in the vertical direction again. The drone measurement component can record the time length of flying from the top of target component 1 to the top of target component 2 or from the top of target component 2 to the top of target component 1, and the time length can be used to assist in correcting the flight altitude change of the drone 1 and the horizontal distance value between target component 1 and target component 2. It should be noted that the drone measurement component includes a drone 1 and a placement frame 2. The placement frame 2 is a rectangular frame structure formed by welding a number of rods. The drone 1 can be placed on the placement frame 2. The drone 1 performs lifting and horizontal movement under the control of its matching remote control. A rangefinder 9 is installed on the lower surface of the drone 1. The rangefinder 9 can measure the vertical distance between it and the target component 1 or the target component 2 below. The rangefinder 9 is wirelessly connected to the smart terminal through a wireless data interaction module. The wireless data interaction module includes but is not limited to a WIFI module, a Bluetooth module or a 2.4G wireless module. The rangefinder 9 can transmit the measured distance value to the smart terminal.

[0020] The intelligent terminal can receive the position data output by target component 1 and target component 2, and use the received position data to calculate the horizontal distance between target component 1 and target component 2. The intelligent terminal can be a smart phone, iPad or laptop computer.

[0021] Both positioning module 1 5 and positioning module 2 8 are GPS positioning modules or Beidou positioning modules. Both positioning module 1 5 and positioning module 2 8 can transmit their positioning location data, i.e., longitude and latitude data, to the smart terminal. The smart terminal uses the two received longitude and latitude data to calculate the straight-line distance value between positioning module 1 5 and positioning module 2 8 in the horizontal direction.

[0022] The intelligent terminal calculates the slope of the soil slope according to the slope calculation formula. The slope calculation formula is: (1); Wherein, S is the slope, α is the slope angle, H1 is the distance between the rangefinder 9 and the baffle 4 in the vertical direction; H2 is the distance between the rangefinder 9 and the baffle 7 in the vertical direction, and L is the linear distance between the positioning module 5 and the positioning module 8 in the horizontal direction.

[0023] It should be noted that the drone 1 can adjust its position through manual correction or image acquisition correction to ensure that the drone 1 can hover directly above baffle 1 4 or baffle 2 7. The manual correction method is that the ground operator adjusts the hovering position of the drone 1 with the naked eye and ensures that the drone 1 can hover directly above baffle 1 4 or baffle 2 7. The image acquisition correction method is to install a camera on the lower surface of the drone 1, and the camera is wirelessly connected to the smart terminal. The camera can capture images directly below the drone 1, and the images captured by the camera can assist the staff in correcting the position of the drone 1 and ensure that the drone 1 can hover directly above baffle 1 4 or baffle 2 7.

[0024] In the process of implementing the technical solution of this application, the staff needs to first arrange the target component 1 at the top of the slope, connect the bracket 1 3 to the ground at the top of the slope and ensure that the baffle 1 4 can be kept horizontal. Similarly, arrange the target component 2 at the bottom of the slope, connect the bracket 2 6 to the ground at the bottom of the slope and ensure that the baffle 2 7 can be kept horizontal. At this time, the intelligent terminal obtains the longitude and latitude data of the target component 1 and the longitude and latitude data of the target component 2 through the positioning module 1 5 and the positioning module 2 8 and calculates the distance value L between the target component 1 and the target component 2 in the horizontal direction. Subsequently, the staff remotely controls the drone 1 to take off from the placement rack 2. It should be noted that the placement rack 2 can be arranged near the bracket 1 3 or the bracket 2 6, and the placement rack 2 can be detachably connected with the bracket 1 3 or the bracket 2 6. When the drone 1 takes off to the specified height and hovers, the staff controls the drone 1 to maneuver horizontally to just above baffle 1 4 or baffle 2 7, and then controls the rangefinder 9 through the intelligent terminal to start measuring the vertical distance between it and baffle 1 4 or baffle 2 7, thereby obtaining H1 and H2, and then directly calculates the slope S of the soil slope through the slope calculation formula.
