[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0046] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] Embodiments of the present application provide a method, device, electronic device, and storage medium for detecting and controlling a drying process of agricultural products.

[0048] In a first aspect, the present application provides a device for detecting and controlling a drying process of agricultural products, comprising a fixing plate 100 , a camera 200 and a light-emitting element 210 .

[0049] The fixing plate 100 is fixedly arranged in the drying chamber. The fixing plate 100 is provided with a camera through hole and a fill light through hole.

[0050] Exemplarily, a heat insulating shell is disposed on the fixing plate 100 .

[0051] The camera 200 is disposed on the fixing plate 100, and the lens 230 of the camera 200 is installed at the camera through hole of the fixing plate 100. The camera 200 can obtain images of the surface of the agricultural products in the drying chamber to assist in determining the degree of dryness of the agricultural products.

[0052] Exemplarily, the camera 200 is a monocular camera; however, in another embodiment, the camera 200 is a binocular camera. In another embodiment, the camera 200 is a multi-eye camera.

[0053] For example, the camera 200 is located in the heat-insulating housing. The stability and durability of the device in the drying chamber are ensured by the design of the fixing plate 100 and the possible heat-insulating housing. In particular, when the camera 200 is fixed to the fixing plate 100 by means of a structure such as the first fixing bracket 220, its stability can be further enhanced to prevent displacement or damage caused by vibration or temperature changes.

[0054] Exemplarily, the camera 200 is directly fixed on the fixing plate 100 by welding, gluing, clamping or bolting. However, in another embodiment, as Figure 1 As shown, a first fixing bracket 220 is fixedly disposed on the fixing plate 100 . The first fixing bracket 220 is a Z-shaped plate structure. One end of the first fixing bracket 220 is fixedly disposed on the fixing plate 100 , and the other end of the first fixing bracket 220 is fixedly disposed with a camera 200 .

[0055] The light emitting member 210 can emit light, and the light emitting member 210 is disposed at the light-filling through hole of the fixing plate 100. Exemplarily, the light emitted by the light emitting member 210 is irradiated onto the agricultural products to increase the surface brightness of the agricultural products and improve the quality of the surface image of the agricultural products obtained by the camera 200.

[0056] Exemplarily, the light emitting element 210 includes, but is not limited to, a light emitting diode, a laser diode, an organic electroluminescent diode, a fluorescent tube, a neon lamp, and the like.

[0057] More than two fill-light through holes are arranged at equal intervals in the circumferential direction around the axis of the camera through hole, and the number of light-emitting elements 210 matches the number of fill-light through holes.

[0058] For example, Figure 2 As shown, two fill-light through holes are arranged at equal intervals in the circumferential direction around the axis of the camera through hole, and two light-emitting members 210 are arranged accordingly. In another embodiment, three fill-light through holes are arranged at equal intervals in the circumferential direction around the axis of the camera through hole, and the three fill-light through holes are distributed in a herringbone shape, and three light-emitting members 210 are arranged accordingly. In another embodiment, four fill-light through holes are arranged at equal intervals in the circumferential direction around the axis of the camera through hole, and four light-emitting members 210 are arranged accordingly.

[0059] By providing a camera through hole and a fill light through hole on the fixing plate 100, and installing the camera 200 and the light emitting element 210 respectively, it can be ensured that the camera 200 can clearly obtain the image of the surface of the agricultural product in the drying chamber. The light emitted by the light emitting element 210 irradiates the agricultural product, improves the brightness of the surface of the agricultural product, and thus improves the quality of the image, making the subsequent judgment of the degree of drying of the agricultural product more accurate.

[0060] The number of fill-in light holes and the number of light-emitting elements 210 are matched, and the fill-in light holes are evenly spaced around the axis of the camera hole, so that light can be evenly irradiated on the agricultural products to avoid image distortion or shadows caused by too strong or too weak light. This design optimizes the fill-in light effect and further improves the image quality.

[0061] like Figure 1 As shown, in one embodiment, the agricultural product drying process detection and control device further includes a first heat dissipation fan 310 , a second heat dissipation fan 320 and a heat dissipation block 330 .

[0062] The first cooling fan 310 is disposed on the fixing plate 100 and is located near the camera 200. The first cooling fan 310 is used to dissipate heat from the camera 200. The operating temperature of the camera 200 has a certain influence on its image quality. Too high a temperature may cause image distortion or increase in noise. By lowering the operating temperature of the camera 200 by the first cooling fan 310, the image quality can be kept stable, ensuring that the surface image of the agricultural product obtained is clear and accurate.

[0063] The second heat dissipation fan 320 is disposed on the fixing plate 100 and is located close to the light emitting element 210 .

[0064] The heat dissipation block 330 is disposed between the light emitting element 210 and the second heat dissipation fan 320. The heat generated by the light emitting element 210 can be conducted to the heat dissipation block 330, and the second heat dissipation fan 320 can dissipate the heat from the heat dissipation block 330.

[0065] The camera 200 and the light-emitting element 210 may generate a certain amount of heat when working, especially when working continuously for a long time. Excessive temperature may affect the performance and life of the camera 200 and the light-emitting element 210. By providing the first cooling fan 310 and the second cooling fan 320, the camera 200 and the light-emitting element 210 can be effectively cooled respectively to keep them within a suitable operating temperature range, thereby improving the stability and reliability of the entire device. Through effective heat dissipation design, the operating temperature of the camera 200 and the light-emitting element 210 can be reduced, thereby extending their life and reducing failures and maintenance costs caused by overheating.

[0066] like Figure 1As shown, in one embodiment, a second fixing bracket 340 is disposed on the fixing plate 100, and the second cooling fan 320 is disposed on the second fixing bracket 340. Exemplarily, the second fixing bracket 340 is fixedly disposed on the fixing plate 100 by welding, clamping, gluing or bolting.

[0067] Exemplarily, the second fixing bracket 340 is a rectangular frame structure, which reduces obstructions and improves air flow efficiency.

[0068] The rectangular parallelepiped frame structure design of the second fixing bracket 340 enables the second cooling fan 320 to be more firmly mounted on the fixing plate 100, while reducing obstructions and improving air flow efficiency. This helps to dissipate heat more effectively, reduce the operating temperature of components such as the light emitting element 210 and the camera 200, and thus improve the stability and life of the device.

[0069] like Figure 1 As shown, in one embodiment, a fixing seat 240 is disposed at the light-filling through hole of the fixing plate 100 , and the light-emitting element 210 is disposed on the fixing seat 240 .

[0070] Exemplarily, the fixing seat 240 is fixed on the fixing plate 100 by welding, clamping, gluing or bolting.

[0071] The setting of the fixing seat 240 enables the light emitting element 210 to be more firmly installed at the fill light through hole, reducing displacement or damage caused by vibration or temperature change, etc. This helps to maintain the stability and luminous efficiency of the light emitting element 210, thereby optimizing the fill light effect and improving the image quality.

[0072] In one embodiment, the agricultural product drying process detection and control device further includes a heat insulating element, a heating element and a scraper.

[0073] The heat insulating member is made of a transparent material. By way of example, the transparent material includes but is not limited to: glass, and high temperature resistant transparent plastic.

[0074] Exemplarily, a first thermal insulation member 410 is provided at one end of the inner wall of the camera through hole away from the camera 200, and the first thermal insulation member 410 is used to isolate the camera 200 and the drying chamber, thereby reducing the impact of the high temperature in the drying chamber on the camera 200; a second thermal insulation member 420 is provided at one end of the inner wall of the fill light through hole away from the light-emitting member 210, and the second thermal insulation member 420 is used to isolate the light-emitting member 210 and the drying chamber, thereby reducing the impact of the high temperature in the drying chamber on the light-emitting member 210.

[0075] However, in another embodiment, a first heat insulating member 410 is provided at one end of the inner wall of the camera through hole away from the camera 200, and no heat insulating member is provided at one end of the inner wall of the fill light through hole away from the light emitting member 210. In another embodiment, a second heat insulating member 420 is provided at one end of the inner wall of the fill light through hole away from the light emitting member 210, and no heat insulating member is provided at one end of the inner wall of the camera through hole away from the camera 200.

[0076] By respectively arranging the first heat insulating member 410 and the second heat insulating member 420 on the inner walls of the camera through hole and the fill light through hole, the high temperature environment in the drying chamber can be effectively isolated, and the direct thermal impact of the high temperature on the camera 200 and the light-emitting member 210 can be reduced, thereby improving their working stability and service life.

[0077] A heating element is provided in the first thermal insulation member 410 and the second thermal insulation member 420, and the heating element is used to heat the first thermal insulation member 410 and the second thermal insulation member 420. When the temperature difference between the first thermal insulation member 410 and the second thermal insulation member 420 and the drying chamber is too large, water vapor will condense on the first thermal insulation member 410 and the second thermal insulation member 420, and the heating element can evaporate the condensed water mist to ensure the transparency of the first thermal insulation member 410 and the second thermal insulation member 420, ensure the quality of the image taken, and ensure the brightness of the light irradiated by the light-emitting member 210 on the agricultural products.

[0078] However, in another embodiment, a heating element is provided in the first thermal insulation member 410, and no heating element is provided in the second thermal insulation member 420. In another embodiment, a heating element is provided in the second thermal insulation member 420, and no heating element is provided in the first thermal insulation member 410.

[0079] Exemplarily, the heating element includes, but is not limited to, a resistance heater, an electromagnetic heater, an infrared heater, a gas heater, and the like.

[0080] Two scrapers are provided on the fixed plate 100 , one of which is located on the fixed plate 100 close to the first thermal insulation member 410 . The scraper is used to scrape the end surface of one side of the first thermal insulation member 410 away from the camera 200 to scrape off condensed water droplets on the first thermal insulation member 410 .

[0081] Another scraper is located on the fixing plate 100 near the second heat insulating member 420 , and the scraper is used to scrape the end surface of one side of the second heat insulating member 420 away from the light emitting member 210 to scrape off the condensed water droplets on the second heat insulating member 420 .

[0082] By arranging a scraper on the fixing plate 100, the condensed water droplets on the heat insulating member can be easily scraped off, thereby maintaining the cleanliness and transparency of the heat insulating member. This design not only improves the maintenance convenience of the mechanical structure, but also helps to extend its service life.

[0083] In a second aspect, the present application provides a method for detecting and controlling a drying process of agricultural products, such as Figure 3 and Figure 4 As shown, the steps of the method include:

[0084] S100: putting agricultural products into a drying chamber. Exemplarily, the drying chamber can heat the agricultural products, and the drying chamber can adjust the internal temperature and humidity, etc.

[0085] S200: The agricultural product drying process has at least one drying stage, and the temperature T corresponding to each drying stage is preset in the drying chamber. YN , relative humidity R YN , agricultural product surface image C YN and weight M YN For example, Figure 4 As shown, the drying process of agricultural products is divided into three stages, namely, the initial drying stage, the intermediate drying stage and the final drying stage. Of course, in another embodiment, the drying stage of agricultural products can be further subdivided into other drying stages, for example, the intermediate drying stage is subdivided into a temperature rise stage, a humidity extraction stage, etc. For the convenience of describing and understanding the technical solution of the present application, the technical solution of the present application is described below by taking the above three drying stages as an example.

[0086] Preset temperature T for starting the drying phase Y1 , relative humidity R Y1 , agricultural product surface image C Y1 and weight M Y1 .

[0087] Preset temperature T for intermediate drying stage Y2 , relative humidity R Y2 , agricultural product surface image C Y2 and weight M Y2 .

[0088] Preset temperature T for finishing the drying phase Y3 , relative humidity R Y3 , agricultural product surface image C Y3 and weight M Y3 .

[0089] S300: Continuously dry agricultural products.

[0090] S400: Acquiring the actual surface image C of the agricultural product S , weight M S and internal temperature T S , determine the drying stage of the agricultural product. For example, the camera 200 of the agricultural product drying process detection and control device in the above embodiment is used to obtain the actual surface image C of the agricultural product. S The actual weight M of agricultural products is obtained through weight sensors S; Obtain the actual internal temperature T of agricultural products through temperature sensors S .

[0091] S500: Obtaining the actual ambient temperature T in the drying chamber H and actual humidity P H , adjust the actual ambient temperature T according to the drying stage of the agricultural products H Size to the temperature T of the corresponding drying stage YN Within the range, adjust the actual humidity P H To the relative humidity R of the corresponding drying stage YN within the range.

[0092] For example, the actual ambient temperature T in the drying chamber is obtained by a temperature sensor. H , obtain the actual humidity P in the drying chamber through the humidity sensor H .

[0093] By adjusting the temperature and humidity in the drying room to match the drying stage of the agricultural products, the adverse effects of the temperature and humidity in the drying room on the drying process of the agricultural products can be avoided, thereby improving the drying efficiency and quality of the agricultural products.

[0094] The method provided by the embodiment of the present application can accurately determine the drying stage of the agricultural product by presetting the parameters such as temperature, relative humidity, surface image and weight of the agricultural product in each drying stage, and obtaining the actual surface image, weight and internal temperature of the agricultural product in real time. According to the judgment result, the temperature and humidity in the drying chamber are adjusted in time to match the drying stage of the agricultural product, avoiding the adverse effects of temperature and humidity on the drying process, thereby significantly improving the drying efficiency and drying quality of the agricultural product. The method allows different drying stages and corresponding parameters to be preset according to the characteristics of different types, shapes and sizes of agricultural products. This flexibility enables the method to be applicable to various types of agricultural products, improving its scope of application and adaptability. The method realizes intelligent and automatic monitoring and control of the drying process of agricultural products. This not only reduces manual intervention and labor intensity, but also improves the accuracy and reliability of control. Since the method can accurately control the temperature and humidity in the drying chamber, unnecessary energy waste is avoided, which helps to achieve the goal of energy conservation and emission reduction. By continuously monitoring the drying process of agricultural products and adjusting the drying parameters in time according to actual conditions, the method helps to optimize the drying process and improve the quality and added value of agricultural products.

[0095] like Figure 4 and Figure 5 As shown, in one embodiment, the actual surface image C of the agricultural product is obtained. S The steps include:

[0096] S210: Preset to obtain the actual surface image C of the agricultural product S The interval period Z.

[0097] S220: Preset a first preset time and a second preset time, increase the surface brightness of the agricultural product within the interval period Z, and obtain the surface image C of the agricultural product within the second preset time S , the duration of increasing the brightness of the surface of the agricultural product is a first preset time.

[0098] Exemplarily, the brightness of the surface of the agricultural product is improved by the light emitting element 210 in any of the above embodiments; the surface image C of the agricultural product is obtained. S This is achieved by the camera 200 in any of the above embodiments.

[0099] For example, if Z=10 minutes, the actual surface image C of the agricultural product is acquired every 10 minutes. S , relative humidity R YN , agricultural product surface image C YN and weight M YN At the initial moment of this interval cycle, the timing of the first preset time is started. The first preset time is, for example, 15 seconds, which means that the light-emitting element 210 continues to emit light for 15 seconds. After the light-emitting element 210 emits light, the timing of the second preset time is started. The second preset time is, for example, 5 seconds, which means that the camera is started to obtain the surface image C of the agricultural product after the light-emitting element 210 emits light for 5 seconds. S .

[0100] S230: If the agricultural product surface image C S If it does not meet the preset standard, the surface image C of the agricultural product is acquired again. S For example, the preset standard is clarity, noise, etc.

[0101] like Figure 3 and Figure 4 As shown, in one embodiment, the method further includes:

[0102] The normal operating temperature T of the preset light emitting element 210 YF For example, the light emitted by the light emitting element 210 is used to increase the surface brightness of the agricultural products.

[0103] Get the actual temperature T of the light emitting element 210 F , adjust the actual temperature T F To normal use temperature T YF For example, the actual temperature T of the light emitting element 210 is obtained by a temperature sensor. F .

[0104] For example, when adjusting the actual temperature T F Greater than normal use temperature TYF When the actual temperature T F Lower than normal use temperature T YF When the temperature of the light emitting element 210 is increased by the heating element.

[0105] like Figure 5 As shown, in one embodiment, the agricultural product drying process detection and control method further includes:

[0106] The normal operating temperature T of the preset camera 200 YS For example, the camera 200 is used to obtain the actual surface image C of the agricultural product. S .

[0107] Get the actual temperature T of the camera 200 S , adjust the actual temperature T S To normal use temperature T YS For example, the actual temperature T of the camera 200 is obtained by a temperature sensor. S ; When the actual temperature T of the camera 200 S Greater than normal use temperature T YS When the actual temperature T of the camera 200 is lowered, the temperature of the camera 200 is reduced by the first heat sink.
