Description

Technical Field

[0001] This utility model relates to the field of forest tree measurement technology, and in particular to an automatic monitoring instrument for the diameter growth of standing trees. Background Technology

[0002] Currently, the core of regular forest resource surveys conducted by various countries, through the establishment of permanent or temporary fixed sample plots, lies in measuring the diameter of trees at breast height (DBH). However, the measurement of standing tree diameter is currently mainly carried out manually both domestically and internationally. When surveyors enter the forest, they use tools such as calipers or measuring tapes to measure the diameter or make manual estimations. The measurement data is read and recorded manually, which is time-consuming, labor-intensive, involves a large workload, is difficult to measure, and lacks accuracy, seriously affecting the accuracy and efficiency of forest resource inventory. Utility Model Content

[0003] To address the aforementioned issues, an automatic monitoring instrument for the diameter growth of standing trees is provided, aiming to solve the problems existing in the prior art.

[0004] The specific technical solution is as follows:

[0005] An automatic monitoring device for the diameter growth of standing trees includes a housing, a battery unit, a mechanical embracing unit, a circuit board, and a transmission unit. The battery unit is detachably installed at the bottom of the housing. The mechanical embracing unit and the circuit board are both disposed within the housing. An embracing outlet is provided on the side of the housing. The monitoring end of the mechanical embracing unit extends out from the embracing outlet. The transmission unit is disposed at the top of the housing. The transmission unit, the mechanical embracing unit, and the battery unit are all electrically connected to the circuit board.

[0006] The aforementioned automatic monitoring instrument for standing tree diameter growth also has the following features: the housing includes a base shell, a base cover, and a top cover; the base shell has an opening at the top; the base cover can be closed onto the opening at the top of the base shell; the bottom of the base shell is detachably connected to the battery unit; the top cover can be closed onto the base cover; the mechanical circumferential part is disposed in the space between the base shell and the base cover; the circuit board is disposed in the space between the base cover and the top cover; and the circumferential outlet is opened on the side wall of the base shell.

[0007] The beneficial effects of the above solution are: the base shell, base cover and top cover are used to isolate two spaces, and the circuit board and mechanical parts are placed in the two spaces respectively to avoid interference.

[0008] The aforementioned automatic monitoring instrument for standing tree diameter growth also has the following features: the mechanical encircling part includes a spring box, a radial magnet, and a steel strip. The steel strip is wound around the spring box, and the spring box provides the pull-back force for the steel strip. An opening is provided at the center of the top surface of the spring box, and the radial magnet is located at the opening. When the steel strip extends outward under the action of an external force, it can drive the spring box and the radial magnet to rotate simultaneously. When the external force is removed, the spring box causes the extended steel strip to rewind. The radial magnet is magnetically connected to the circuit board.

[0009] The beneficial effects of the above scheme are: the external force pulls the steel belt to drive the radial magnet to rotate. Since the magnetic encoder on the circuit board can detect the rotation of the radial magnet, the elongation of the steel belt can be calculated, and thus the diameter of the tree can be obtained.

[0010] The aforementioned automatic monitoring instrument for standing tree diameter growth also has the following features: the mechanical circling part further includes a hook, which is disposed on the outer side wall of the base shell and adjacent to the circling outlet; a hanging ring is provided at one end of the steel strip extending from the spring box; when the steel strip has circled the tree once, the hanging ring can cooperate with the hook to keep the steel strip in the state of circling the tree.

[0011] The beneficial effects of the above scheme are: the hanging ring and hook work together to allow the steel belt to wrap around the tree, and the spring box can tighten the steel belt, so that the steel belt and the instrument as a whole remain wrapped around the tree.

[0012] The aforementioned automatic monitoring instrument for the diameter growth of standing trees also has the following feature: the transmission unit includes an antenna and an extension shell. The antenna is vertically mounted on the circuit board, and the extension shell is mounted on the top cover. When the top cover is closed on the base cover, the antenna extends into the extension shell.

[0013] The beneficial effects of the above solution are: protecting both the antenna and the circuit board inside the top cover and the extended shell, thus preventing the external environment from affecting them.

[0014] In summary, the beneficial effects of this scheme are:

[0015] The automatic tree diameter growth monitor provided by this utility model uses a mechanical circumference unit that surrounds the tree to be monitored. This mechanical circumference unit works in conjunction with a circuit board. Based on the length of the steel strip output by the mechanical circumference unit, the tree diameter can be calculated. Furthermore, the tree diameter can be wirelessly transmitted to an external receiving device for continuous monitoring. This automatic tree diameter growth monitor provided by this utility model has the effect of monitoring tree diameter and continuously monitoring tree growth diameter. Attached Figure Description

Figure 2 This is an exploded view of the automatic monitoring instrument for standing tree diameter growth according to this utility model. Figure 3 This is a top view schematic diagram of the automatic monitoring instrument for standing tree diameter growth of this utility model, as shown below. Figures 1-3 As shown, the automatic monitoring instrument for standing tree diameter growth provided in this embodiment includes a housing, a battery unit 10, a mechanical circumferential unit, a circuit board 6, and a transmission unit.

A circumferential outlet is provided on the side of the housing. The monitoring end of the mechanical circumferential unit extends out from the circumferential outlet. The transmission unit is disposed at the top of the housing. The transmission unit, the mechanical circumferential unit, and the battery unit 10 are all electrically connected to the circuit board 6.

[0024] In the above embodiment, the housing includes a base shell 1, a base cover 2, and a top cover 3. The base shell 1 has an opening at the top, and the base cover 2 can be closed onto the opening at the top of the base shell 1. The bottom of the base shell 1 is detachably connected to the battery part 10. The top cover 3 can be closed onto the base cover 2. A mechanical circumferential part is disposed in the space between the base shell 1 and the base cover 2. The circuit board 6 is disposed in the space between the base cover 2 and the top cover 3. The circumferential outlet is opened on the side wall of the base shell 1.

[0025] In the above embodiment, the mechanical encircling part includes a spring barrel 4, a radial magnet 5, and a steel strip. The steel strip is wound around the spring barrel 4 and the spring barrel 4 provides a pull-back force for the steel strip. An opening is provided at the center of the top surface of the spring barrel 4, and the radial magnet 5 is disposed at the opening. When the steel strip extends outward under the action of an external force, it can drive the spring barrel 4 and the radial magnet 5 to rotate simultaneously.

[0026] It should be noted that a magnetic encoder is installed on the circuit board 6, which can measure the rotation angle of the radial magnet 5.

[0027] In the above embodiment, the mechanical encircling part also includes a hook 7, which is disposed on the outer side wall of the base shell 1 and is adjacent to the encircling outlet.

When the top cover 3 is closed on the base cover 2, the antenna 8 extends into the extension shell 9.

[0029] It should be noted that the formula for calculating tree diameter is:

[0030] L=(L0+θ×r n ) / π

[0031] In the formula: L0 is the initial length, L represents the diameter length, θ represents the rotation angle of the magnetic encoder, n represents the number of turns of the spring, and r n This indicates the radius corresponding to the number of wrapping turns.

[0032] Working principle: During the radial growth of the tree, as the diameter of the tree gradually increases, the length of the steel strip also increases. As the steel strip extends, the spring box 4 and the radial magnet 5 rotate simultaneously. The magnetic encoder measures the rotation angle of the radial magnet 5, and the diameter of the tree can be calculated by the rotation angle of the radial magnet 5. After obtaining the tree diameter data, it is wirelessly transmitted to the external receiving device.
