Description

Technical Field

[0001] The invention relates to the technical field of plant sample plot measuring instruments, in particular to equipment for automatically identifying and measuring plant sample plots. Background Art

[0002] Comprehensive forest and grassland monitoring - grassland monitoring selects three 1m×1m small sample plots for yield measurement in the sample plot specified in its "Technical Regulations" for cutting and weighing. When cutting, all plants in the sample plot are cut at the ground level. According to the 2024 "Technical Regulations", 4,410 sample plots will be surveyed nationwide. It is calculated that the cut grassland area in the country will reach 13,230 square meters in 2024 alone. If the continuous monitoring is carried out for 10 years, the cut area will reach 132,300 square meters.

[0003] This not only caused great damage to the grassland ecosystem, but also irreversible damage to the extremely fragile high-altitude alpine meadow grassland. On the other hand, the cutting tools (scissors) were primitive and backward, which brought great inconvenience to the investigators and took a lot of time to cut and sort.

[0004] In order to prevent the direct impact of monitoring on grassland area and reduce the workload of investigators, it is necessary to invent a device to make monitoring methods better serve ecological protection. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a device for automatically identifying and measuring plant sample plots.

[0006] In order to solve the above technical problems, the present invention is implemented by the following technical solutions: an automatic identification and measurement plant sample quadrat device, comprising a housing, one side of the housing is detachably connected to an interactive display, one side of the housing is retractably connected to a weighing device, the bottom end of the housing is fixedly connected to a support frame, and one side of the bottom end of the housing is provided with a laser projector and a camera;

[0007] The interior of the housing also includes a central processing unit and a battery. The central processing unit is electrically connected to the interactive display, and the battery supplies power to the central processing unit. The weighing equipment, laser projector and camera are all electrically connected to the central processing unit.

[0008] In some embodiments, a placement groove is provided on one side of the housing, and an interactive display is placed on the inner wall of the placement groove.

[0009] In some embodiments, the inner wall of the placement slot is provided with an electrical plug connector, which can be electrically connected to the interactive display placed on the inner wall of the placement slot.

[0010] In some embodiments, a drawer slot is provided on one side of the housing, and the inner wall of the drawer slot is slidably connected to the weighing device for storing and drawing the weighing device.

[0011] In some embodiments, the support frame is composed of a triangular support and a support rod, and the triangular support is located at the bottom end of the support rod.

[0012] In some embodiments, the support rod is configured as a telescopic rod, the length of which can be changed by adjustment, and the triangular bracket is configured to be foldable for easy storage.

[0013] In some embodiments, a laser projector outputs a laser beam of a predetermined shape to illuminate the land to produce a projection light range;

[0014] The light output end of the laser projector is arranged to be adjustable, so as to adjust the projection size as required.

[0015] In some embodiments, the projected light is arranged in a square shape.

[0016] In some embodiments, a plant identification algorithm is built into the central processing unit, the algorithm may use Baidu plant identification, and the identified plant type is displayed and illustrated through an interactive display.

[0017] In some embodiments, the interactive display automatically calculates the total weight of the species in the sample plot by selecting the name of the dominant planting species through operation, combining the sample weight, camera recognition function, and laser sample plot range.

[0018] The beneficial effects of the present invention are:

[0019] 1. Traditional monitoring methods often require cutting a large amount of grassland vegetation to obtain samples, which directly damages the grassland ecosystem, especially for the fragile high-altitude meadow grassland. The automatic identification and measurement of plant sample plots equipment avoids cutting operations through non-destructive monitoring methods, significantly reducing the degree of damage to grassland vegetation;

[0020] 2. The device integrates multiple functional modules such as cameras, laser projectors, sample weighing platforms and interactive displays, which can realize rapid identification, accurate weighing and data analysis of plant species in the sample plot. This not only improves the efficiency and accuracy of monitoring, but also reduces errors caused by human factors;

[0021] 3. Traditional monitoring methods require investigators to carry a lot of tools and perform tedious cutting, sorting and weighing operations. The automatic identification and measurement of plant sample plots equipment simplifies the operation process. Investigators only need to perform simple sample collection and touch screen operations to complete the monitoring task, which greatly reduces the workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A drawer slot 12 is provided on one side of the housing 1, and the inner wall of the drawer slot 12 is slidably connected to the weighing device 3 for storing and drawing the weighing device 3;

[0029] The support frame 6 is composed of a triangular support 61 and a support rod 62. The triangular support 61 is located at the bottom end of the support rod 62. The support rod 62 is configured as a telescopic rod, and the length can be changed by adjustment. The triangular support 61 is configured to be foldable for easy storage.

[0030] A laser projector 4 and a camera 5 are arranged on one side of the bottom end of the housing 1, and the internal output of the laser projector 4 is square;

[0031] The housing 1 also includes a central processing unit 7 and a battery 8. The central processing unit 7 is electrically connected to the interactive display 2. The battery 8 supplies power to the central processing unit 7. The weighing device 3, the laser projector 4 and the camera 5 are all electrically connected to the central processing unit 7.

[0032] The central processor 7 is internally provided with a plant identification algorithm, which may be Baidu plant identification, and the identified plant type is displayed and illustrated through the interactive display 2 .

[0033] The interactive display 2 selects the name of the dominant planting species through operation, and automatically calculates the total weight of the species in the sample plot in combination with the sample weight, camera recognition function, and laser sample plot range.

[0034] In summary, the present invention has the following working principles:

[0035] First, the investigators used the equipment to project a 1m×1m sample area on the grassland to be monitored. Then, the camera began to capture plant images in the sample area and identified the plant species through a plant recognition algorithm.

[0036] After identifying the plant species in the sample plot, the investigators will manually collect different types of grass seed samples and place them on the sample weighing table for on-site weighing. The weighing table will transmit the weight data to the central processing in real time;

[0037] The investigators select the name of the dominant planting species through the detachable screen and enter relevant parameters (such as sample area, number of samples collected, etc.). The central processor will automatically calculate the total weight of the species in the sample based on this information, combined with the plant species identified by the camera, sample weight and laser sample range;

[0038] Finally, the central processor will store all monitoring data in the internal memory and can generate detailed monitoring reports. These reports can be used for subsequent ecological analysis and protection strategy formulation.

[0039] The equipment not only significantly improves the efficiency and accuracy of grassland monitoring, but also greatly reduces the damage to the grassland ecosystem. By reducing the mowing area and simplifying the operation process, it effectively reduces the workload of investigators and allows them to focus more on ecological protection work.
