Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image recognition, in particular to an agricultural product drying device based on image recognition. BACKGROUND

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry and fishery, i.e. plants, animals and microorganisms obtained in agricultural activities and their products, such as rice, highland barley, sorghum, peanuts, corn, wheat and local specialties in various regions. Agricultural products are usually used for production and processing to obtain agricultural and sideline products. Before forming the above-mentioned agricultural and sideline products, they usually need to be dried. At present, drying devices are usually used for drying. However, a large amount of agricultural products are usually poured into the drying device together for drying. The agricultural products are stacked together and cannot be heated uniformly. The moisture content of the agricultural products is different, and the drying process usually uses fixed temperature and fixed time, which cannot accurately judge the drying degree, resulting in the appearance of completely dried, incompletely dried and over-dried agricultural products, reducing the drying efficiency and the qualified rate of agricultural products. SUMMARY

[0003] In order to solve the problem that the existing agricultural product drying device cannot uniformly dry and accurately judge the drying degree of agricultural products, thereby reducing the drying efficiency and the qualified rate, the present application provides an agricultural product drying device based on image recognition. The device comprises:

[0004] The grouping module is used for dividing the target product based on the grouping component to obtain a plurality of first groups.

[0005] The conveying module is used for conveying the first group to the drying module based on the first conveying component to obtain the first weight of the first group.

[0006] The parameter module is used for obtaining the first drying parameter based on the first weight.

[0007] The drying module is used for drying the first group based on the drying component and the first drying parameter to obtain a second group.

[0008] The first weight module is used for obtaining the second weight of the second group based on the second conveying component.

[0009] The calculation module is used for obtaining the first weight difference based on the first weight and the second weight, judging whether the moisture content of the second group meets the first preset range based on the first weight difference, if yes, transmitting the second group to the collecting component based on the second conveying component, and if not, returning the second group to the drying module based on the re-drying component, and updating the first group to the second group.

[0010] A collecting module is configured to collect the first group based on the collecting component.

[0011] The application divides the target products into groups, and dries them in batches, solves the problem that the products cannot be heated uniformly because a large amount of target products are poured into a drying device to be dried and the products are stacked together; obtains drying parameters of each batch according to the weight before drying, combines the water content of each batch, obtains different drying parameters, which are more suitable for the drying of each batch, and the drying can be more accurately performed; and judges whether the target product is completely dried according to the weight difference before and after drying, and if not, the target product is dried again, so that the drying degree can be more accurately judged, and the drying efficiency and the qualified rate are improved.

[0012] Further, the device further comprises an image recognition module, which is configured to: acquire a first image of the first group and a second image of the second group based on a collecting component, identify the first image and the second image based on a pre-trained recognition model, obtain a drying identification result, and transmit the drying identification result to the calculation module.

[0013] The calculation module obtains a comprehensive detection result based on the first weight difference and the drying identification result, and updates the first weight difference to the comprehensive detection result.

[0014] During the drying process of the agricultural products, the outer surface gradually loses water and becomes dry. As the water content decreases, the volume decreases and the color changes, for example, the highland barley gradually changes from dark green to yellow brown. In addition, the surface may have some small cracks due to the evaporation of water, which helps to further reduce the water content. The application compares the images before and after drying, and comprehensively judges the weight difference before and after drying, so that the drying degree can be more accurately judged, and the drying efficiency and the qualified rate are improved.

[0015] Further, the drying module further comprises a segmented drying module, which is configured to:

[0016] The first group is divided based on a preset drying degree value to obtain third groups at different stages, preset drying parameters of each third group are obtained based on the first weight, and the third groups are dried based on the preset drying parameters to obtain the second group.

[0017] The grouped agricultural products are divided again according to a preset drying degree to obtain drying parameters of each group at different drying degrees, and the drying is gradually performed according to the drying degree, so that the drying can be more accurately performed, and the drying efficiency is improved.

[0018] Further, the drying module further comprises a weight drying module, which is configured to:

[0019] The first group is divided to obtain fourth groups of different stages, a third weight of each fourth group is obtained, a second drying parameter is obtained based on the third weight and a preset weight range, the fourth groups are dried based on the second drying parameter, and the second groups are obtained.

[0020] The grouped agricultural products are divided again according to weight to obtain drying parameters of each group under different weights, and drying is gradually performed according to weight changes, so that drying can be more accurately performed, and drying efficiency is improved.

[0021] Further, the device further comprises a screening module, and the screening module is configured to:

[0022] The second groups are screened based on the screening assembly and a preset wind range to obtain a screening result.

[0025] The first image is recognized based on the pre-trained recognition model to obtain an adhesion recognition result, the first group is separated based on the adhesion recognition result and an adhesion assembly to obtain a fifth group, and the fifth group is conveyed to the drying assembly for drying.

[0026] Some agricultural products may be adhered during harvesting, storage and transportation before drying, for example, raw corn is rich in moisture, but after the corn husk is removed, the moisture is easily volatilized. In order to prevent moisture loss, the endosperm cells in the raw corn will secrete a viscous liquid to cover the surface of the corn kernels, so that the moisture is not evaporated. The liquid is mucus, and the mucus covers the surface of the corn kernels, causing the corn kernels to adhere together. In addition, corn itself contains a certain amount of sugar. When the surface of the corn kernel is damaged, the sugar will be precipitated, further causing the corn kernels to adhere together. At the same time, the starch in corn is mainly composed of amylopectin and amylose. The proportion of amylopectin in ordinary corn is relatively high, and the starch in waxy corn is almost entirely amylopectin. Amylopectin will be gelatinized when heated, resulting in increased stickiness, causing the dried corn kernels to adhere tightly together and be unable to be separated. The present application determines whether there is adhesion by image recognition, and separates the corn kernels by the adhesion assembly if there is adhesion before drying.

The controller obtains the drying parameters of each air-drying component 801 based on the third weight and the preset weight range, and performs drying processing on the fourth group.

[0120] In said S4, the drying method of said drying component 8 may also be:

[0121] Based on the first weight, each segment is preset to correspond to a different weight range, and the initial drying parameters of the first segment are obtained based on the first weight. During the drying process, the controller can control the air-drying component 801 to pause for a preset time, and the weight sensor 702 obtains the real-time weight of the first group in real time, and determines whether the real-time weight is within the weight range corresponding to the segment. If so, the air-drying component 801 is controlled to increase the wind force to blow the first group into the next segment, and the initial drying parameters of the next segment are obtained based on the real-time weight, until the last segment; if not, the weight difference is obtained based on the real-time weight and the weight range corresponding to the segment, and the drying parameters of the air-drying component 801 are updated in real time based on the weight difference, and the first group continues to be dried.

[0122] Example 14

[0123] refer to Figures 1-6 In this embodiment, the method of use may further include screening the target product that has been completely dried:

[0124] The controller obtains the weight difference based on the first weight and the second weight, determines that the second group has been completely dried based on the weight difference, and transmits the second group to the third conveying component 11. The controller starts the fan component 10 and presets the screening weight range. The fan component 10 generates wind force corresponding to the weight range. Under the action of wind force, target products of different weights will move to different distances in the horizontal direction and fall into the first collection component 1201 and the second collection component 1202 respectively, thereby obtaining target products that meet the weight.

[0125] In this embodiment, after S2, the following step may be performed to separate the adhered target products:

[0126] The first conveying component 7 conveys the first group to the fourth conveying component 1701, the acquisition component 15 collects the image of the first group and transmits it to the controller, the pre-trained recognition model of the controller recognizes the image, recognizes the adhered target product, and the controller starts the control component 1703. The control component 1703 controls the rolling plate 1702 to be lowered until it contacts the target product and then moves back and forth and left and right to achieve the purpose of separating the target product. After separation, the first group is conveyed to the drying component for subsequent drying steps.
