Description:SYSTEM FOR DETERMINING QUALITY PARAMETERS OF AGRICULTURAL PRODUCE
Field of the Invention
[0001] The present disclosure generally relates to agricultural quality assessment systems. Further, the present disclosure particularly relates to a system for determining quality parameters of agricultural produce using optical reflectance measurements.
[0002] .
Background
[0003] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0004] The quality assessment of agricultural produce is a key factor in ensuring consumer satisfaction and maintaining market value. Traditionally, manual inspection techniques have been widely utilized for assessing the quality of agricultural products. Such techniques involve visual and tactile inspections performed by trained personnel to evaluate parameters such as color, size, shape, texture, and visible defects. While this method has been effective to a certain extent, it is associated with several limitations, including subjectivity, inconsistency, human fatigue, and inefficiency in high-volume production environments.
[0005] To address the shortcomings of manual inspection, automated systems have been introduced. These systems incorporate imaging technologies, sensor-based analysis, and optical methods to assess various quality parameters of agricultural produce. Common techniques include the use of digital imaging devices that capture visual data, which is then analyzed to determine physical characteristics such as size, shape, and surface defects. Although these systems offer improved speed and consistency over manual methods, they are largely limited to surface-level inspections and often fail to capture internal quality attributes, such as ripeness, moisture content, or chemical composition. Furthermore, certain optical imaging systems are affected by external lighting conditions, leading to variability in the results.
[0006] To overcome these limitations, advanced optical techniques, such as reflectance spectroscopy, have gained traction. These methods provide non-invasive measurement of internal quality parameters by analyzing how light interacts with the produce. Reflectance spectroscopy, in particular, is used to measure how light reflects off the surface of the produce, allowing for the assessment of internal properties like ripeness, sugar content, and moisture levels. However, existing systems using reflectance-based techniques often lack the ability to perform precise and comprehensive quality assessments due to limitations in capturing data from multiple points or angles on the sample.

This feature allows the system (100) to reposition the sample container (104) for additional sensor readings, enhancing the analysis by capturing data from diverse angles. This movement improves the system’s ability to comprehensively assess various aspects of the agricultural produce sample, allowing for more thorough analysis and more accurate determination of quality parameters.
[00060] In an embodiment, the light-emitting elements (110) arranged in a circular array provide omnidirectional illumination to the sample container (104). This configuration allows the light to uniformly illuminate multiple surfaces of the agricultural produce sample during its rotational movement. As a result, the optical sensor (112) is able to capture reflectance data from various angles simultaneously, improving the accuracy of the quality assessment by ensuring comprehensive surface coverage during the measurement process.
[00061] In an embodiment, the wavelength modulation unit in the light-emitting source (108) enables the system (100) to alternate between narrowband and broadband light emissions. By synchronizing the wavelength modulation with the rotation of the sample container (104), the system (100) captures reflectance data across a broader light spectrum. This capability enhances the system’s ability to analyze both surface and internal quality parameters of the agricultural produce sample, leading to a more detailed and comprehensive assessment.
[00062] In an embodiment, the light-emitting source (108) includes a diffusion lens positioned above the light-emitting elements (110). The diffusion lens disperses light evenly across the surface of the sample container (104), reducing localized overexposure and ensuring uniform illumination of the agricultural produce sample. This uniformity in light distribution enhances the quality of the reflectance data captured by the optical sensor (112), resulting in more accurate and consistent quality parameter determinations for the agricultural produce sample.
[00063] In an embodiment, the adjustable mounting structure (102) incorporates a tilting mechanism, allowing the sample container (104) to be adjusted at various angles relative to the optical sensor (112). This mechanism facilitates the measurement of surface irregularities and variations in texture on the agricultural produce sample. The ability to adjust the angle of the sample container (104) enables the optical sensor (112) to capture data from areas that would otherwise be difficult to measure, improving the overall accuracy of the quality assessment.
[00064] In an embodiment, the light-emitting source (108) is mounted on a rotating disc assembly that moves along multiple paths around the sample container (104) during rotational movement. This design allows light to be directed at the sample container (104) from multiple angles, improving the consistency of illumination across all surfaces of the agricultural produce sample. The rotating disc assembly provides enhanced flexibility in light direction, ensuring comprehensive data capture by the optical sensor (112) from all angles.
[00065] In an embodiment, the adjustable mounting structure (102) incorporates a counterweight assembly positioned opposite to the sample container (104). The counterweight assembly balances the load of the sample container (104) during rotational movement, preventing wobbling or uneven rotation. This balance enhances the stability of the sample container (104) during rotation, ensuring smooth motion and reducing potential distortions in the reflectance data captured by the optical sensor (112), resulting in more accurate analysis of the agricultural produce sample.
[00066] FIG. 2 illustrates an architectural diagram of a system 100 to determine quality parameters of an agricultural produce, in accordance with the embodiments of the present disclosure. The system 100 comprises an adjustable mounting structure 102 designed to accommodate a sample container 104, which contains the agricultural produce sample to be analyzed. A motor 106 is operatively connected to the sample container 104 to impart rotational movement to the container, allowing for uniform exposure to light emitted by a light-emitting source 108. The light-emitting source 108 consists of a plurality of light-emitting elements 110, which are configured to direct light towards the rotating sample container 104. An optical sensor 112 is arranged above the sample container 104 to capture light reflected from multiple areas of the produce sample during rotation. Said optical sensor 112 is configured to measure reflectance values at various points of the produce sample. The reflectance data captured by the optical sensor 112 is processed by a processing unit 114, which analyzes the data to determine the quality parameters of the agricultural produce sample. The results are then displayed via a data output interface 116, enabling the user to view the quality parameters of the sample.
[00067] FIG. 3 illustrates multiple views of a system to determine quality parameters of an agricultural produce, in accordance with the embodiments of the present disclosure. The system comprises several key components, each designed to facilitate the accurate assessment of agricultural produce through non-invasive optical measurements. The various views provide a detailed breakdown of the structure and arrangement of the system components, including the removable sensor box, motor, rotating platform, LED array, and the processing electronics.
[00068] In the side view of the system, a container is shown positioned on the rotating platform. Said container is configured to hold an agricultural produce sample and is securely mounted to the platform. The rotational movement of the platform allows the produce sample to be exposed to light from various angles, enabling a comprehensive analysis of the sample's surface characteristics. The rotating platform, as indicated in the front views, is driven by the motor enclosed within the motor cover. The motor imparts rotational movement to the platform, ensuring that the agricultural produce sample rotates smoothly during analysis. The platform itself is wide and sturdy, ensuring that the container remains stable during rotation.
[00069] The removable sensor box, as shown in the various views, is situated above the rotating platform and houses the optical sensing components. The sensor window, located at the base of the sensor box, allows light reflected from the sample to pass through and reach the internal sensors. The sensor box is designed to slide into position using the sensor box sliding bars, which are supported by support pillars that provide structural stability to the system. This arrangement allows for easy removal and replacement of the sensor box, facilitating maintenance or calibration tasks.
[00070] The top view of the sensor box illustrates the LEDs arranged in a circular array. Said LED array provides uniform illumination across the surface of the sample container. The LEDs are disposed in such a way as to ensure omnidirectional illumination of the agricultural produce sample, enabling the system to capture data from multiple angles simultaneously. This uniform light distribution is crucial for ensuring that the optical sensor, located inside the sensor box, can capture accurate reflectance data from various areas of the sample's surface.
[00071] Additionally, the system features a processing board housed at the rear of the structure, as shown in the back view. The processing board is responsible for receiving and analyzing the data captured by the optical sensors. The board is connected to various interfaces, including a Type C port and a power switch button, providing the necessary connections for power and data transmission. The cable management holes located near the processing board ensure that cables are neatly organized, preventing interference with the system’s operational components.
[00072] The motor is illustrated at the base of the platform in multiple views, enclosed within a motor cover for protection. Said motor is responsible for imparting controlled rotational movement to the platform. The unibody platform base provides a stable foundation for the entire system, ensuring that vibrations or external disturbances do not affect the accuracy of the measurements captured by the system.
