Description

Technical Field

[0001] This invention relates to the field of wheat testing technology, and in particular to a portable integrated measurement device for wheat plant height and ear number. Background Technology

[0002] In agricultural production and scientific research, wheat plant height and ear number are key parameters for assessing wheat growth, predicting yield, and conducting breeding research. Traditionally, wheat plant height is measured manually using a ruler or tape measure. This method is not only inefficient but also susceptible to the subjectivity of human operation, making it difficult to guarantee the accuracy and consistency of the measurement results. In large-scale planting scenarios, it requires a significant amount of manpower and time.

[0003] Existing methods for measuring the number of wheat ears mostly rely on visual estimation, which is time-consuming, labor-intensive, and makes it difficult to obtain accurate data.

[0004] With the development of modern precision agriculture, the demand for rapid and accurate acquisition of wheat growth parameters is becoming increasingly urgent. Traditional manual measurement methods can no longer meet this need. Therefore, it is essential to develop an integrated device that can quickly, accurately, and conveniently measure wheat plant height and ear number. Summary of the Invention

[0005] The main objective of this invention is to provide a portable integrated wheat plant height-ear number measurement device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides a portable integrated wheat plant height-ear number measurement device, comprising an electric push rod with its output end facing downwards; a base plate is mounted on the output end of the electric push rod; a pull rope displacement sensor is disposed on the left side of the housing of the electric push rod, and the pull rope end of the pull rope displacement sensor is fixedly connected to the base plate; a battery is disposed on the right side of the housing of the electric push rod; a handle is disposed on the rear side of the housing of the electric push rod; a CCD camera and a controller are disposed on the front side of the housing of the electric push rod; a display is disposed on the top of the housing of the electric push rod; the display, the electric push rod, the pull rope displacement sensor, the battery, and the CCD camera are all electrically connected to the controller.

[0007] Furthermore, the handle is equipped with an up button and a down button that are electrically connected to the controller.

[0008] Furthermore, it also includes an L-shaped background plate, the horizontal plate of which is mounted on the front side of the housing of the electric actuator and located above the CCD camera, and the vertical plate of which is opposite to the CCD camera.

[0009] Furthermore, a proximity switch is installed on the horizontal plate of the background panel, and the proximity switch is electrically connected to the controller.

[0010] Furthermore, it also includes a rope cleaning mechanism, which includes two support shafts, both of which are mounted on the left side of the housing of the electric push rod; cleaning rollers are rotatably mounted on both support shafts; the rope of the rope displacement sensor is located between the two cleaning rollers and is in contact with the two cleaning rollers.

[0011] Furthermore, the battery is detachably connected to the housing of the electric actuator.

[0012] Furthermore, the controller is equipped with a communication module.

[0013] Furthermore, the controller is equipped with a data interface.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention uses an electric push rod to drive the base plate to rise and fall rapidly. Combined with a pull rope displacement sensor and a CCD camera, it can simultaneously measure wheat plant height and ear number. Compared with traditional manual measurement, it significantly shortens the measurement time and improves the accuracy of the measurement results. The entire device is highly integrated, compact in structure, and easy to carry.

[0016] 2. The rope displacement sensor can accurately sense the extension and retraction of the rope, thereby accurately measuring the wheat plant height with millimeter-level precision. The background plate setting improves the image quality captured by the CCD camera, and combined with advanced image recognition algorithms, it can accurately count the number of wheat ears, reducing the subjective error of manual counting.

[0017] 3. The up and down buttons on the handle allow operators to easily control the raising and lowering of the base plate. The controller integrates multiple functions, and the operation process is simple and easy to understand, allowing operators to quickly learn how to use it without professional training. The display shows the measurement data in real time, allowing operators to understand the measurement results promptly.

[0018] 4. All components are compactly mounted on the electric push rod housing, resulting in a small overall structure and light weight. Operators can easily carry the device in the field using the handle, making it suitable for wheat field measurements in different terrains.

[0019] 5. The removable battery design makes it easy to replace, ensuring the device's continuous working capability.

[0020] 6. The rope cleaning mechanism can promptly remove impurities from the rope, ensuring stable measurement accuracy of the rope displacement sensor, reducing measurement errors caused by rope contamination, and improving the long-term measurement stability of the device.

Detailed Implementation

[0024] To achieve the above objectives and effects, the technical means and structure adopted by the present invention will be described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of the present invention.

[0025] like Figure 1-2As shown, this invention provides a portable integrated wheat plant height-ear number measurement device, including an electric push rod 5, the output end of which is set downwards; a base plate 6 is installed on the output end of the electric push rod 5, which can drive the base plate 6 to move up and down when the electric push rod 5 is working, and the base plate 6 can contact the bottom of the wheat during the measurement process, providing a reference for plant height measurement; a pull rope displacement sensor 2 is set on the left side of the housing of the electric push rod 5, the pull rope end of the pull rope displacement sensor 2 is fixedly connected to the base plate 6, and the pull rope will extend and retract accordingly as the base plate 6 moves up and down, the pull rope displacement sensor 2 can accurately measure the moving distance of the base plate 6 by the extension and retraction of the pull rope, and then calculate the wheat plant height by combining the initial position and other parameters; a battery 12 is set on the right side of the housing of the electric push rod 5, the battery 12 provides power support for the operation of the entire device; a handle 1 is set on the rear side of the housing of the electric push rod 5, the handle is designed in accordance with the ergonomic principle, making it convenient for the operator to hold the device for movement and measurement operations; the handle 1 is equipped with an up button 14 and a down button 13 electrically connected to the controller 10, and the operator can press the up button 14 to move the device and perform measurement operations. Pressing the up button 14 or down button 13 controls the electric push rod 5 to raise or lower the base plate 6, making operation simple and intuitive. The electric push rod 5 has a CCD camera 7, a background plate 8, and a controller 10 mounted on its front side. The CCD camera 7 captures images of wheat and uses a specific algorithm to identify and calculate the number of ears. The background plate 8 is L-shaped, with its horizontal section above the CCD camera 7 and its vertical section opposite the CCD camera 7. The background plate 8 uses a single dark color (such as black) design to create a sharp contrast with the wheat, effectively reducing... The surrounding environment is minimized from interference with the captured images, improving the clarity of the images captured by the CCD camera 7 and the accuracy of subsequent ear count identification; a proximity switch 9 is installed on the horizontal plate of the background plate 8; a display 11 is installed on the top of the housing of the electric push rod 5 to display the measured wheat plant height, ear count, and other data in real time, allowing the operator to intuitively understand the measurement results; the display 11, electric push rod 5, pull rope displacement sensor 2, battery 12, CCD camera 7, proximity switch 9, up button 14, and down button 13 are all electrically connected to the controller 10.

[0026] During measurement, the operator holds handle 1 and moves the device next to the wheat to be measured, with the background plate 8 positioned above the wheat. Then, the operator presses the descent button 13, causing the electric push rod 5 to move the base plate 6 downwards, allowing it to land on the soil near the bottom of the wheat. Next, the operator releases the descent button 13, presses the ascent button 14, and keeps the base plate 6 stationary, allowing the background plate 8 to descend. The top of the wheat to be measured enters the space between the vertical plate of the background plate 8 and the CCD camera 7. When the proximity switch 9 detects the top of the wheat, the electric push rod 5 stops moving, and the ascent button 14 is released. The pull rope displacement sensor 2 transmits the measured displacement data to the controller 10. The controller 10 calculates the wheat plant height based on this data and sends the result to the display 11 for display. Simultaneously, the controller 10 controls the CCD camera 7 to take pictures of the wheat in front of the vertical plate of the background plate 8. The CCD camera 7 transmits the captured image to the controller 10, which uses a built-in image recognition algorithm to statistically analyze the number of wheat ears in the image. After the statistics are completed, the controller 10 sends the ear count result to the display 11 for display.

[0027] In another embodiment, a pull-cord cleaning mechanism is also included. This mechanism comprises two support shafts 3, both mounted on the left side of the housing of the electric push rod 5. Cleaning rollers 4 are rotatably mounted on each of the two support shafts 3. The pull cord of the pull-cord displacement sensor 2 is located between and in contact with the two cleaning rollers 4. When the pull cord moves, it drives the cleaning rollers 4 to rotate. The cleaning rollers 4 clean dust and impurities adhering to the surface of the pull cord, preventing impurities from affecting the measurement accuracy of the pull-cord displacement sensor 2 and extending its service life.

[0028] In another embodiment, for easy replacement and charging, the battery 12 and the housing of the electric push rod 5 are detachably connected. When the battery 12 is low on power, the operator can quickly replace it with a spare battery 12 to ensure the continuous operation of the device.

[0029] In another embodiment, the controller 10 includes a microprocessor, a storage module, and a communication module. The microprocessor is responsible for processing various data and instructions, the storage module stores measurement data, and the communication module enables data transmission between the device and external devices (such as computers, mobile phones, etc.) to facilitate subsequent data analysis and management. Furthermore, the controller 10 also has a data interface, allowing direct connection to external devices for data transmission via a data cable.
