Description

Technical Field

[0001] The invention relates to the technical field of tree diameter measurement, in particular to a portable tree diameter automatic laser measuring device. Background Art

[0002] Tree diameter measurement is mainly used in forestry resource surveys, tree yield estimation, tree production monitoring, forest carbon reserve assessment and other fields.

[0003] In forestry resource surveys, measuring the diameter of trees can help forestry workers understand the structure of forests, tree growth, and the overall health of forests. The diameter of trees is a key parameter for estimating tree biomass and carbon storage. Measuring the diameter of trees can provide basic data for studying climate change and carbon cycles, and help monitor carbon emissions and formulate emission reduction strategies, which is crucial for the management and protection of forest resources. There is a certain relationship between the diameter of trees and the volume of wood. Therefore, measuring the diameter can also be used to estimate the amount of wood in a tree, which also plays a very important role in commercial forest planting, timber harvesting plans, and timber sales. In tree growth monitoring, regularly measuring the diameter of trees helps to evaluate the growth rate, health status, and growth trend of trees, which is of great significance for studying tree growth patterns, ecological restoration projects, etc.

[0004] Common portable belt tree diameter rulers, digital tree diameter rulers, and tree diameter calipers in the prior art;

[0005] The disadvantage of tree diameter calipers is that they are generally suitable for trees with smaller and more regular diameters. If the tree's breast diameter is significantly twisted, bent or has an uneven surface, errors are likely to occur during caliper measurement, affecting the measurement accuracy.

[0006] Using a tape caliper requires high operating skills. The tape needs to be kept level and tight to ensure that no errors occur, otherwise inaccurate measurements may occur. At the same time, tree diameter calipers are usually made of metal or wood, which are relatively large and not easy to carry, especially when working in the field for a long time, which may add extra burden.

[0007] Although digital tree diameter rulers have overcome the above shortcomings, their electronic components may be affected by environmental factors such as temperature and humidity. In extreme temperature or high humidity environments, the accuracy and stability of the equipment may be affected. Users also need to have certain operating skills to ensure the accuracy of the measurement.

[0008] Laser diameter gauge is a precise instrument commonly used in industrial diameter measurement. Its principle is to cooperate with a laser transmitter and a laser receiver. A lens is set on one side of the laser transmitter to scatter the point light source into a line light source. The diameter measuring object passes between the laser receiver and the laser transmitter, and the diameter of the measured object is detected according to the obstruction of the light path. However, the laser diameter gauges currently used in industry are usually desktop structures, which are not convenient to carry and use. Handheld laser diameter gauges can often only be used to detect the diameter of tiny workpieces and are not suitable for the diameter detection of trees. In view of this, in-depth research on the above-mentioned problems resulted in this case. In view of this, in-depth research on the above-mentioned problems resulted in this case.

[0046] Example:

[0047] See also Figure 1-9 In the modern tree diameter measurement process, conventional diameter measurement methods include caliper measurement and infrared measurement, which have many inconveniences and the measurement results are not accurate enough. Laser diameter measurement is a more precise measurement method, but the current laser diameter measurement device is mainly based on workpiece measurement. If used in tree diameter measurement, the current laser diameter measurement device is not portable enough and has many inconveniences in operation.

[0048] According to the instruction manual Figure 1 -Attached Fig. 9 It can be seen that in view of the above problems, the present application discloses a portable tree diameter automatic laser measuring device, including a handheld part, which is the main frame part of the device, wherein the handheld part is a holding frame 1 and a detection frame 2, the holding frame 1 is assembled on one side of the detection frame 2, and the holding frame 1 is held by a person during the detection process, and the detection frame 2 is a rectangular frame structure, one side of the detection frame 2 is open, and a laser detection structure for detection is integrated on the detection frame 2, and the detection frame 2 and the holding frame 1 are fused through a telescopic adjustment component 3, and the telescopic adjustment component 3 plays a role in connecting the detection frame 2 and the holding frame 1, and can also adjust the detection frame 2 to extend a certain length, so as to facilitate the detection of trees that are inconvenient for personnel to pass through, or the position of trees that cannot be reached;

[0049] Specifically, the laser detection structure is composed of a laser transmitter 4 and a laser receiver 5. The laser transmitter 4 and the laser receiver 5 are symmetrically arranged on the detection frame 2. The laser transmitter 4 is arranged corresponding to the laser receiver 5. The principle of detection is that the laser transmitter 4 shoots the laser toward the tree and the laser receiver 5, and the diameter of the tree is determined according to the position of the laser beam blocked by the tree.

[0050] Furthermore, the laser transmitter 4 is integrated on the transmitting base 41, and the transmitting base 41 is fixedly connected to one side of the detection frame 2. The transmitting lens 42 of the laser transmitter 4 is arranged on the transmitting base 41, and the laser receiver 5 is integrated on the receiving base 51. The receiving base 51 is arranged on the other side of the detection frame 2 corresponding to the transmitting base 41, and the receiving lens 52 of the laser receiver 5 corresponds to the position of the transmitting lens 42. The laser transmitter 4 and the laser receiver 5 are installed and arranged based on the transmitting base 41 and the receiving base 51, and the transmitting base 41 and the receiving base can be prefabricated to achieve unified specifications. The two sides of the detection frame 2 are provided with mounting positions corresponding to the transmitting base 41 and the receiving base 51. The transmitting base 41 and the receiving base 51 are fixed on the mounting positions by screws, and the mounting positions match the specifications of the transmitting base 41 and the receiving base 51, respectively, and are arranged relatively, so that after the laser receiver 5 and the laser transmitter 4 are installed in place, the two naturally form a corresponding relationship;

[0051] The laser emitter 4 is provided with a laser light source in the emission base 41, and a polygonal prism is provided on one side corresponding to the laser light source, the polygonal prism is connected to the rotating motor, and a reflector is provided on one side of the polygonal prism corresponding to the emission prism, the rotating motor and the laser light source are connected to the master control processor. The principle of the laser emitter 4 is to generate laser through the laser light source, and the laser light source is refracted by the polygonal prism and then passes through the reflector to form a detection light path, and the light path forms a detection light beam through the action of the emission lens 42.

[0052] Furthermore, the principle of the laser receiver 5 is that a receiving element is provided on one side of the receiving lens 52 in the receiving base 51 of the laser receiver 5. The receiving element is connected to the main control processor. The receiving lens 52 receives the light beam emitted by the laser transmitter 4. Since part of the light beam is blocked by trees, the receiving lens 52 gathers the light beam and hits the receiving element. The receiving element is a photosensitive element. The electrical signals emitted by the receiving element are different according to the intensity of the light received by the photosensitive element. After receiving the electrical signals, the main control processor converts these electrical signals into display data.

The transmission component 7 can drive the ring frame 21 to rotate on the transition seat 6, and then the ring frame 21 drives the detection frame 2 to rotate around the ring frame 21 as the center, so that the laser transmitter 4 and the laser receiver 5 rotate correspondingly around the tree axis as the axis, so as to detect trees with tree diameters in different directions;

[0054] Then, a posture control clamp 8 is extended from one side of the transition seat 6. The posture control clamp 8 is a symmetrical elastic clamping structure. The posture control clamp 8 is used to clamp the tree so that the detection frame 2 can be kept perpendicular to the center of the tree during detection.

[0055] In order to facilitate the observation of trees, the master control processor is arranged on one side of the holding frame 1. Specifically, the master control processor is arranged on one side of the holding frame 1, and a display screen is arranged on one side of the holding frame 1 and connected to the master control processor;

[0056] Since the device is handheld, in order to ensure the battery life of the device, the power supply of the device is replaceable. Specifically, a split power supply unit 9 is provided on the handheld frame on one side of the master control processor, and the split power supply unit 9 is used to power the automatic measuring device.

[0062] In the specific implementation process, the movement of the circumferential frame 21 controls the movement of the transmission gear 73 through the transmission motor 72, so that the transmission gear 73 engages with the circumferential tooth groove 22, and then the circumferential tooth groove 22 drives the circumferential frame 21 to move. Since the center of the circumferential tooth groove 22 is located at the axial position of the circumferential frame 21, the circumferential frame 21 can produce axial rotation, and then the circumferential frame 21 drives the laser transmitter 4 and the laser receiver 5 on the detection frame 2 to be located at different radial positions of the tree, thereby realizing the detection of tree diameters at different positions.

[0063] According to the instruction manual Figure 1 -Attached Figure 7It can be seen that the telescopic adjustment component 3 includes a telescopic rod 31, the end of the telescopic rod 31 is connected to the transition seat 61, the end of the telescopic rod 31 and the central axis of the telescopic rod 31 are provided with an adjustment threaded hole, a telescopic sleeve 32 is provided on one side of the holding frame 1, the telescopic rod 31 is inserted in the telescopic sleeve 32, a telescopic adjustment screw 33 is provided in the telescopic sleeve 32 and meshed with the adjustment threaded hole, the end of the telescopic adjustment screw 33 passes through one side of the telescopic sleeve 32, and the end of the telescopic adjustment screw 33 is connected to the telescopic adjustment swivel seat 34.

When it is necessary to control the detection frame 2 to extend to different positions, the telescopic adjustment seat 34 is used to rotate the telescopic adjustment screw 33, so that the telescopic adjustment screw 33 is engaged with the adjustment threaded hole of the telescopic rod 31, and then the telescopic rod 31 is controlled to drive the transition seat 61 at the end to move linearly. Due to the cooperation between the transition seat 61 and the ring frame 21, the transition seat 61 can drive the detection frame 2 to move. The telescopic sleeve 32 is a hollow tube with an oblong cross-section. The cross-section of the telescopic rod 31 is an oblong structure.
