Description

Technical Field

[0001] The invention belongs to the technical field of forestry investigation equipment, in particular to a field surveying and mapping device used for forestry investigation. Background Art

[0002] As an important part of the earth's ecosystem, forestry plays an irreplaceable role in maintaining biodiversity, regulating climate, and conserving water and soil. Forestry surveys are the basis for scientific management and rational use of forest resources, and are crucial for formulating forestry policies, planning forestry development, monitoring forest health, and evaluating forest ecological service functions.

[0003] Field surveying is one of the core links of forestry surveys, which is directly related to the quality and efficiency of data collection. Through field surveying, we can accurately obtain information such as tree species, distribution, quantity, growth status, pests and diseases, etc., which provides a scientific basis for forest resource assessment, ecological protection, and disaster warning, and is a key step in achieving sustainable development of forestry.

[0004] The thickness of trees is one of the important indicators of tree growth. By regularly measuring the thickness, we can understand the growth rate and amount of trees. The growth of the thickness can reflect the growth status of trees.

[0005] The existing technology cannot measure the thickness of trees by manually attaching the field surveying device to the trunk of the tree due to the obstruction of the tree branches. Therefore, it is necessary to propose a field surveying device for forestry survey. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a field surveying device for forestry surveys. Through a laser radar, a first driving member and a rotating disk, the field surveying device can avoid tree branches and better fit the tree trunk to measure the thickness of the tree trunk.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a field surveying and mapping device for forestry investigation, comprising a box body, a baffle is provided in the box body to separate the box body into a first chamber and a second chamber, openings are provided on both sides of the first chamber, a horizontal component and an energy supply component for keeping the box body horizontal are provided in the second chamber, a clamping component for clamping a tree trunk and measuring the thickness of the tree trunk is provided in the first chamber, the clamping component extends to the outside of the box body through the opening, a rotating disk for adjusting the horizontal angle of the box body is provided at the bottom of the box body, a first driving member for driving the rotating disk to rotate is provided on the rotating disk, a gripping component is provided at the bottom of the rotating disk, a display component for displaying tree thickness data is provided on the gripping component, and a detection component for detection is provided at the top of the box body;

[0008] The detection component includes a laser radar, a controller is fixedly connected in the box, the laser radar and the first driving component are respectively connected to the controller signal, and the controller, the laser radar and the first driving component are respectively electrically connected to the energy supply component.

[0009] The principle of the basic scheme is: by emitting a laser beam through the laser radar and receiving its reflected signal, the position of the tree trunk can be accurately measured and located. The controller receives the measurement data from the laser radar and then drives the first drive member to rotate the rotating disk to align the field mapping device with the tree trunk.

[0010] The beneficial effects of the basic scheme are: 1. LiDAR identification of the location of tree trunks helps to significantly improve the accuracy of tree measurements.

[0011] 2. The rotating disk can make the field surveying device rotate 360° horizontally, which is helpful for surveying personnel to measure the thickness of tree trunks in all directions.

[0012] Furthermore, the energy supply component includes a battery, which is fixedly connected to the bottom of the second chamber, and the controller, the laser radar and the first driving member are all electrically connected to the battery.

[0013] The beneficial effect of the basic solution is that the battery can ensure the smooth operation of the field surveying and mapping equipment when working in the field, reducing the occurrence of inability to complete the surveying and mapping tasks due to lack of electricity.

[0014] Further, the clamping assembly includes a plurality of first clamping sections and a second clamping section, the first clamping section and the second clamping section are symmetrically arranged on both sides of the box body, the first clamping section is fixedly connected to the bottom of the first chamber, the first clamping section extends to the outside of the box body through the opening, a slide rail is arranged inside the first clamping section, the second clamping section is slidably matched with the first clamping section through the slide rail, the second clamping section is composed of a plurality of clamping blocks, the clamping blocks are hinged by cylindrical blocks, a rolling assembly is arranged at one end of the second clamping section away from the first clamping section, the rolling assembly includes a plurality of rolling gear rings, the rolling gear rings are symmetrically arranged along the height direction of one end of the second clamping section, the rolling gear rings are rotatably connected to the second clamping section, a plurality of claw hooks are circumferentially fixedly connected to the outer side of the rolling gear ring, a second driving member is arranged inside the rolling gear ring, the second driving member is connected to the controller signal, and the second driving member is used to drive the rolling gear ring to rotate;

[0015] An electronic tape measure is fixedly connected in the first chamber, the electronic tape measure is connected to the controller signal, and both ends of the tape measure pass through the second clamping section and are fixedly connected to the rolling gear ring.

[0016] The beneficial effects of the basic scheme are: the rolling gear ring rotating along the tree trunk is conducive to driving the extension of the second clamping section, so that the second clamping section moves along the tree trunk, the cylindrical block is conducive to limiting the displacement of the second clamping block in the vertical direction, and the second clamping block can freely move in the horizontal direction, which is conducive to making the second clamping section better adhere to the tree trunk. The rolling gear ring drives the electronic tape measure to measure the thickness of the tree trunk, which is conducive to improving the accuracy of measuring the thickness of the tree trunk.

[0017] Furthermore, one end of the second clamping section away from the first clamping section is fixedly connected with a Hall sensor, the Hall sensors are located between the rolling gear rings, and the battery is electrically connected to the Hall sensor.

[0018] The beneficial effect of the basic solution is that after the claw hooks touch each other, the Hall sensors will contact each other, which will cause the Hall voltage to change. The controller will receive the change in the Hall voltage and control the second drive member to stop driving and thus stop the rolling gear ring from rotating.

[0019] Furthermore, the horizontal component includes a gyroscope and an electric universal joint, both of which are fixedly connected to the bottom of the second chamber. The electric universal joint is connected to the controller signal, and the controller is used to control the electric universal joint based on the gyroscope detection information to keep the box level.

[0020] The beneficial effects of the basic scheme are: the gyroscope is conducive to detecting the offset angle of the box, and the controller controls the electric universal joint to adjust the offset angle of the box, which is conducive to improving the stability of the field surveying and mapping device and reducing the attitude changes caused by vibration and wind changes. It is conducive to the field surveying and mapping device to maintain high measurement accuracy and stability in complex environments.

[0021] The holding component further includes a telescopic hand-held rod, and the display component includes a display screen, which is fixedly connected to the bottom of the telescopic hand-held rod, and the display screen is connected to the controller signal.

[0022] The beneficial effect of the basic solution is that the telescopic hand-held pole can be freely extended and retracted, which is beneficial for field surveying personnel to adjust the height of the hand-held pole and is beneficial for measuring the thickness of trees of different heights.

[0023] Furthermore, a camera is fixedly connected to the top of the box, the camera is signal-connected to the controller, and the camera is electrically connected to the battery.

[0024] The beneficial effect of the basic solution is that the camera is connected to the display screen signal, and the field surveying and mapping personnel can observe the growth status of the top-level trees and the health of the leaves through the camera, which is conducive to the field surveying and mapping personnel to better complete the surveying and mapping work.

[0025] Furthermore, a laser rangefinder for measuring the height of the box from the ground is fixedly connected to the bottom of the box, the laser rangefinder is connected to the controller signal, and the laser rangefinder is electrically connected to the battery.

[0026] The beneficial effect of the basic scheme is that the laser rangefinder can measure the height of the location of the measured tree thickness from the ground and display the data on the display screen, which is conducive to improving the data of field mapping.

[0027] Furthermore, an anti-skid pad is sleeved on the bottom of the telescopic hand-held rod.

[0028] The beneficial effect of the basic solution is that when field surveyors conduct surveying, the anti-skid pad helps to increase the friction between the telescopic hand-held rod and the hand of the field surveyor, so that the field surveyor can more stably fix the field surveying device on the tree trunk.

[0029] Furthermore, a GPS locator is fixedly connected in the second chamber.

[0030] The beneficial effects of the basic solution are: the GPS locator is conducive to continuously sending the location information of field surveying and mapping personnel and field surveying and mapping equipment to the satellite, which is conducive to locating the position of field surveying and mapping personnel and reducing the occurrence of field surveying and mapping personnel losing contact.

[0035] The following is further described in detail through specific implementation methods:

[0036] Embodiment 1:

[0037] Basically as attached Figure 1 , Figure 2and Figure 3 As shown: a field surveying and mapping device for forestry investigation, comprising a box body 1, a baffle is provided in the box body 1 for dividing the box body 1 into a first chamber 12 and a second chamber 10, both sides of the first chamber 12 are provided with openings, a horizontal component and an energy supply component for keeping the box body 1 horizontal are provided in the second chamber 10, a clamping component for clamping a tree trunk and measuring the thickness of the tree trunk is provided in the first chamber 12, the clamping component extends to the outside of the box body 1 through the opening, a rotating disk 6 for adjusting the horizontal angle of the box body 1 is provided at the bottom of the box body 1, a first driving member for driving the rotating disk 6 to rotate is provided on the rotating disk 6, the first driving member is conducive to driving the rotating disk 6 to adjust the rotation position of the field surveying and mapping device, and is conducive to better aligning the field surveying and mapping device with the tree trunk, a gripping component is provided at the bottom of the rotating disk 6, a display component for displaying tree thickness data is provided on the gripping component, and a detection component for detection is provided on the top of the box body 1;

[0038] The detection component includes a laser radar 3, which is useful for emitting laser to identify the position of the tree trunk. A controller is fixedly connected to the box 1 by bolts. The laser radar 3 and the first drive are respectively connected to the controller signal, and the controller, the laser radar 3 and the first drive are respectively electrically connected to the energy supply component.

[0039] The energy supply component includes a battery 19, which is useful for supplying energy to the field surveying and mapping device. The battery 19 is fixedly connected to the bottom of the second chamber 10 by bolts, and the controller, the laser radar 3 and the first drive member are all electrically connected to the battery 19.

[0040] The holding assembly includes a telescopic hand-held rod 9, which is conducive to adjusting the height of the field surveying and mapping device. The display assembly includes a display screen 14, which is fixedly connected to the bottom of the telescopic hand-held rod 9 by bolts. The display screen 14 is connected to the controller signal, and the display screen 14 is electrically connected to the battery 19.

[0041] The specific implementation process is as follows: First, the field surveying and mapping personnel need to charge the battery 19 of the field surveying and mapping device. After ensuring that the charging is completed, the field surveying and mapping device can be carried out for field surveying and mapping operations. When performing field surveying and mapping operations, the battery 19 of the field surveying and mapping device must first be turned on. Then the field staff determines the position and height where the thickness of the tree trunk needs to be measured. The field surveying and mapping personnel adjust the telescopic hand-held rod 9 to an appropriate height. Finally, the field surveying and mapping device is lifted and aimed at the position of the tree trunk that needs to be measured. At this time, the laser radar 3 will start working. The laser radar 3 will continuously emit lasers to scan and determine the data of the tree trunk, branches, leaves, etc., and then transmit the position data of the tree trunk, branches, leaves, etc. determined by the laser radar 3 to the controller. The controller determines the position of the tree trunk and then controls the rotating disk 6 to rotate through the first drive member, so that the clamping assembly avoids the branches and leaves of the tree and fits the tree trunk.

[0042] Embodiment 2:

[0043] The difference from the above embodiment is that the clamping assembly includes a plurality of first clamping sections 11 and second clamping sections 4, the first clamping sections 11 and second clamping sections 4 are symmetrically arranged on both sides of the box body 1, the first clamping sections 11 are fixedly connected to the bottom of the first chamber 12 by bolts, the first clamping sections 11 extend through the opening to the outside of the box body 1, the first clamping sections 11 are provided with slide rails inside, the second clamping sections 4 are slidably matched with the first clamping sections 11 through the slide rails, the second clamping sections 4 are composed of a plurality of clamping blocks 18, the clamping blocks 18 are hinged by cylindrical blocks 17, the second clamping sections 4 are provided with a rolling assembly at one end away from the first clamping section 11, the rolling assembly includes a plurality of rolling gear rings 5, the rolling gear rings 5 ​​are symmetrically arranged along the height direction of one end of the second clamping section 4, the rolling gear rings 5 ​​are rotatably connected to the second clamping section 4, the outer circumferential side of the rolling gear ring 5 is fixedly connected with a plurality of claw hooks by bolts, a second driving member is provided inside the rolling gear ring 5, the second driving member is connected to the controller signal, and the second driving member is used to drive the rolling gear ring 5 to rotate;

[0044] An electronic tape measure is fixedly connected to the first chamber 12 by bolts. The electronic tape measure is useful for measuring the thickness of the tree trunk. The electronic tape measure is connected to the controller signal. Both ends of the tape measure pass through the second clamping section 4 and are fixedly connected to the rolling teeth 5 by bolts.

[0045] One end of the second clamping section 4 away from the first clamping section 11 is fixedly connected with a Hall sensor 7 by bolts. The Hall sensor 7 is located between the rolling gear rings 5 ​​, and the battery 19 is electrically connected to the Hall sensor 7 .

[0046] The specific implementation process is as follows: after the field surveying and mapping device is attached to the tree trunk, the controller will control the second driving member to work, and the second driving member will drive the rolling gear ring 5 to rotate, and then the claw hook will clamp the tree trunk and move circumferentially along the trunk. While the claw hook moves circumferentially along the tree trunk, it will drive the second clamping section 4 to slide out of the slide rail of the first clamping section 11. Because the second clamping sections 4 are hinged by cylindrical blocks 17, the cylindrical blocks 17 can limit the displacement of the second clamping section 4 in the vertical direction, and the second clamping block 18 can move freely in the horizontal direction, so the second clamping section 4 can move circumferentially along the tree trunk driven by the claw hook.

[0047] When the claw hook and the second clamping section 4 move circumferentially along the tree trunk, the rolling gear ring 5 will continuously pull out the electronic tape measure. When the claw hooks touch each other, the second clamping section 4 can be close to the tree trunk. At this time, the electronic tape measure can also complete the measurement of the tree trunk. The electronic tape measure directly transmits the measured thickness of the tree trunk to the controller, and the controller transmits it to the display component, which is convenient for field surveying and mapping personnel to view.

[0048] Because the rolling gear rings 5 ​​are fixedly connected with the Hall sensors 7 by bolts, when the claw hooks touch each other, a Hall voltage will be generated between the Hall sensors 7. When the controller detects this Hall voltage, it will control the rolling gear ring 5 to stop moving through the second driving member, thereby reducing the situation where the rolling gear ring 5 continues to run but cannot move, causing the rolling gear ring 5 to be overloaded.

[0049] Embodiment 3:

[0050] The difference from the above embodiment is that the horizontal component includes a gyroscope 13 and an electric universal joint, both of which are fixedly connected to the bottom of the second chamber 10 by bolts, and the electric universal joint is connected to the controller signal. The controller is used to control the electric universal joint to keep the box 1 horizontal based on the detection information of the gyroscope 13. The gyroscope 13 monitors the deflection angle of the box 1, and the controller controls the electric universal joint to adjust the horizontal angle of the box 1. The cooperation between the gyroscope 13 and the electric universal joint is conducive to improving the stability of the box 1 and reducing the posture changes caused by vibration and wind changes.

[0051] The specific implementation process is as follows: when field surveyors conduct field surveying work, due to the harsh field surveying environment and complex surveying conditions, if the thickness of the tree trunk is measured at a position higher than the ground, the messy branches of the trees will block the field surveyors' line of sight and make it impossible to accurately judge whether the field surveying device is level. At this time, the gyroscope 13 in the second chamber 10 is needed to detect whether the angle of the box 1 is offset. After the angle of the box 1 is offset, the controller will control the electric universal joint to adjust the angle of the box 1 so that the box 1 always remains level.

[0052] Embodiment 4:

[0053] The difference from the above embodiment is that a camera 2 is also fixedly connected to the top of the box body 1 by bolts, the camera 2 is connected to the controller signal, and the camera 2 is electrically connected to the battery 19. The camera 2 is helpful for field surveying and mapping personnel to observe the growth status of the top-level trees and the health of the leaves.

[0054] The specific implementation process is as follows: when field surveying and mapping personnel conduct field surveying and mapping work, they also need to observe the growth and health status of trees. The presence of camera 2 can capture the growth of leaves and branches of trees, and camera 2 can also capture the growth of tree trunks, whether there are problems such as rot, etc. The images captured by camera 2 can be directly transmitted to the display screen 14 through the controller, which is beneficial for field surveying and mapping personnel to directly observe the growth and health status of trees through the display screen 14.

[0055] Embodiment 5:

[0056] The difference from the above embodiment is that a laser rangefinder 15 for measuring the height of the box 1 from the ground is fixedly connected to the bottom of the box 1 by bolts, the laser rangefinder 15 is connected to the controller signal, and the laser rangefinder 15 is electrically connected to the battery 19. The laser rangefinder 15 is conducive to measuring the surveying height of the field surveying and mapping device and improving the field surveying and mapping data.

[0057] The specific implementation process is as follows: when field surveyors measure the trunk thickness of trees, the laser rangefinder 15 can measure the height of the measured trunk thickness from the ground, which is conducive to better improving the data of field surveying tasks.

[0058] Embodiment 6:

[0059] The difference from the above embodiment is that an anti-skid pad 8 is sleeved on the bottom of the telescopic handle rod 9 , and the anti-skid pad 8 is helpful to increase the friction between the human hand and the telescopic handle rod 9 .

[0060] The specific implementation process is as follows: when surveying in the field, the telescopic hand-held rod 9 may slip due to the continuous sweating of the human hands, thereby causing the field surveying device to be broken. Therefore, an anti-slip pad 8 is provided at the bottom of the telescopic hand-held rod 9 to increase the friction between the human hands and the telescopic hand-held rod 9, thereby reducing the occurrence of the telescopic hand-held rod 9 slipping from the human hands.

[0061] Embodiment 7:

[0062] The difference from the above embodiment is that a GPS locator 16 is fixedly connected to the second chamber 10 by bolts, and the GPS locator 16 is helpful for determining the positions of field surveying personnel and field surveying equipment.

[0063] The specific implementation process is as follows: Forestry surveys are mostly conducted in the field, and the GPS locator 16 is conducive to continuously sending the location information of field surveying and mapping personnel and field surveying and mapping equipment to the satellite, which is conducive to the logistics support personnel to continuously monitor the location of field surveying and mapping personnel and reduce the occurrence of situations where positioning cannot be achieved due to loss of mobile phone signals.
