Description

Technical Field

[0001] This disclosure relates to the technical field of grain warehouse environmental monitoring, specifically to a grain warehouse environmental monitoring and regulation device and method. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] As a vital commodity, the safe storage of grain is of paramount importance. Grain warehouses, as key storage facilities, have a decisive impact on the quality and shelf life of grain. Factors such as temperature, humidity, porosity, and carbon dioxide concentration, if not effectively monitored and regulated, will directly affect the storage effectiveness and long-term safety of grain. With the ever-increasing demand for grain storage, environmental monitoring of grain warehouses has become increasingly crucial. Therefore, accurately monitoring and adjusting various environmental parameters within grain warehouses has become a key step in ensuring the safety of grain storage.

[0004] Traditional grain storage monitoring devices have limitations in the process of monitoring the grain storage environment. Existing monitoring methods and equipment generally suffer from insufficient monitoring accuracy and low levels of intelligence. Specifically, traditional environmental monitoring devices typically require multiple sensors to be installed inside the storage facility, and it is difficult to adjust the sensor positions in real time to adapt to environmental changes in different locations. Current grain storage temperature and humidity monitoring devices often can only collect data from certain areas within the storage facility, failing to achieve comprehensive monitoring of the entire storage space. Therefore, it is impossible to accurately grasp the temperature and humidity changes in different areas, nor can it understand the distribution of carbon dioxide concentration within the storage facility in real time. At the same time, existing devices usually cannot effectively adjust the grain storage environment when problems are detected. This means that when abnormalities occur in temperature, humidity, carbon dioxide concentration, etc., it is impossible to take corresponding adjustment measures in a timely manner, which may affect the preservation effect of grain. Especially in large-scale grain storage facilities, once environmental anomalies occur, relying on manual adjustments to grain storage is not only extremely labor-intensive but also inefficient, making it difficult to guarantee the stability and safety of grain storage. Summary of the Invention

[0005] To address the aforementioned issues, this disclosure proposes a grain storage environment monitoring and adjustment device and method. It presents a plug-and-play pre-embedded device that enables comprehensive monitoring of the environment at different depths within the grain storage facility. Furthermore, when a problem is detected in the storage environment, it can adjust the ventilation of the corresponding area, thus achieving unattended automated grain storage monitoring.

[0006] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0007] One or more embodiments provide a grain storage environment monitoring and control device, including a linkage device and a control device; the linkage device includes an inner pipe and an outer pipe nested together.

[0008] Within the pipe wall space formed by the inner and outer pipes, sensing components are arranged sequentially from top to bottom.

[0009] The area on the external pipe corresponding to the sensor component is set with a mesh structure to form a channel for gas to flow to the sensor component;

[0010] The inner pipe is movably installed inside the outer pipe. A first through hole is provided on the inner pipe. After the inner pipe moves relative to the outer pipe, the mesh structure communicates with the first through hole at a set height, so as to realize the air circulation from the inside of the inner pipe to the outside of the outer pipe.

[0011] One or more embodiments provide a monitoring and control method for a grain storage environment monitoring and control device based on the above, comprising the following steps:

[0012] Acquire environmental data from different locations within the grain silo;

[0013] Based on the detected temperature, humidity, and carbon dioxide concentration, interpolation methods are used to predict the temperature field, humidity field, and carbon dioxide distribution inside the grain silo.

[0014] Based on the predicted temperature field, humidity field, and carbon dioxide distribution, the locations of data anomalies are identified as locations requiring ventilation. Control commands are then generated to control the ventilation of the corresponding drive devices and ventilation systems.

[0015] Compared with the prior art, the beneficial effects of this disclosure are as follows:

[0016] The nested design of the inner and outer pipes disclosed herein helps improve the structural stability of the device and reduces interference from external factors on the sensors. The sensing components are arranged sequentially from top to bottom along the space between the inner and outer pipe walls, enabling multi-point monitoring of the grain silo environment at different heights. The area on the outer pipe corresponding to the sensing components is designed with a mesh structure. Gas in the grain can diffuse to the sensing components through the mesh structure of the mesh cover. Simultaneously, the mesh structure effectively prevents large particles from entering the pipe, ensuring a clean working environment for the sensors, reducing the impact of impurities on sensor accuracy, and extending the sensor's lifespan. The inner and outer pipe walls can move relative to each other, allowing for adjustable ventilation at different heights, ensuring that gas can smoothly flow into the detection area of ​​the grain silo when needed, thereby achieving both monitoring and ventilation regulation of the grain silo environment.

The embodiments will now be described in detail with reference to the accompanying drawings.

[0030] Example 1

[0031] In one or more of the technical solutions disclosed in the embodiments, such as Figures 1 to 4 As shown, a grain warehouse environment monitoring and regulation device includes a linkage device 1 and a control device 2. The linkage device 1 includes an inner pipe 18 and an outer pipe 10 nested together; and a series of sensing components 13 arranged from top to bottom within the pipe wall space formed by the inner pipe 18 and the outer pipe 10.

[0032] The area on the outer pipe 10 corresponding to the sensor component 13 is set as a mesh structure 12 to form a channel for gas to flow to the sensor component 13;

[0033] The inner pipe 18 is movably installed inside the outer pipe 10. A first through hole 17 is provided on the inner pipe 18. After the inner pipe 18 moves relative to the outer pipe 10, the mesh structure 12 communicates with the first through hole 17 at a set height, so as to realize the air circulation from the inner pipe 18 to the outside of the outer pipe 10.

[0034] In this embodiment, the nested design of the inner pipe 18 and the outer pipe 10 helps improve the structural stability of the device and reduces interference from external factors on the sensor. The sensing component 13 is arranged sequentially from top to bottom along the space between the inner and outer pipes 10, enabling multi-point monitoring of the grain silo environment at different heights. The area on the outer pipe 10 corresponding to the sensing component 13 is set as a mesh structure 12. Gas in the grain can diffuse to the sensing component 13 through the mesh structure on the mesh cover. At the same time, the mesh structure 12 can effectively prevent large particles from entering the pipe, ensuring a clean working environment for the sensor, reducing the impact of impurities on the sensor's accuracy, and extending the sensor's service life. The inner and outer pipe walls can move relative to each other, allowing for ventilation at different heights, ensuring that gas can flow smoothly into the detection area of ​​the grain silo when needed, thereby realizing the monitoring and ventilation regulation of the grain silo environment.

[0035] When in use, the connecting rod device 1 of this device is pre-embedded in the grain silo to be measured, which can predict the environmental parameters of the grain silo, including temperature, humidity, porosity and carbon dioxide content. At the same time, it can ventilate according to the monitoring results to ensure the preservation effect of the grain.

[0036] In some embodiments, the sensing component 13 includes, but is not limited to, a temperature and humidity sensor 13-1 and a carbon dioxide concentration sensor 13-2;

[0037] Specifically, the porosity detection device includes a pressure sensor that reacts to changes in porosity based on changes in air pressure.

[0038] The transmission line of the sensing component is connected to the signal acquisition device set on the upper end face of the connecting rod device 1 through the space of the tube wall. The signal acquisition device is connected to the control device 2, and the control device 2 transmits or processes the acquired signal.

[0039] In some embodiments, the area on the outer pipe 10 corresponding to the area where the sensing component 13 is disposed is set as a mesh structure 12. Specifically, the outer pipe 10 is provided with an opening of a set size, the mesh structure 12 is fixed at the opening and extends inward to a set depth, such that the inner surface of the mesh structure 12 is spaced apart from the outer surface of the inner pipe 18 by a set distance to form a receiving space 19 for the sensing component 13, and the sensing component 13 is disposed on the inner surface of the mesh structure 12.

[0040] Preferably, the sensing component 13 is disposed on the inner surface of the mesh structure 12 at a predetermined distance from the outer surface of the inner pipe 18.

[0041] The mesh structure 12 in this embodiment is a three-dimensional structure with a certain thickness. Optionally, the mesh structure can be set as a multi-layer mesh superposition structure, or the mesh structure 12 can be a honeycomb-like structure.

[0042] Optionally, the mesh structure 12 can be configured as a fan shape.

[0043] A further technical solution is to set one or more sensing components at the same height as the sensing component 13. Each sensing component is set at the opening of the pipe wall on the outer pipe 10 through the mesh structure 12. A first interval space 10-1 is formed between the mesh structures 12 at the same height.

[0044] Optionally, when the sensing components 13 are set as a group at the same height, one or more mesh structures 12 are set at the same height position, and the mesh structures 12 at the same height are spaced apart to form a first interval space 10-1; for example Figure 4 As shown in the diagram, a cross-sectional structure diagram of a sensing component 13 is set on the same floor, and multiple mesh structures 12 are set on the same plane height to improve ventilation.

[0045] During use, air can be introduced through the inner pipe 18 and vented out through the mesh structure 12 to the outer pipe 10 to regulate the grain storage environment, such as cooling, and ensure the grain storage effect.

[0046] In some embodiments, to improve the stability and durability of the device and to achieve ventilation control at different heights, a filler 11 is provided in the pipe wall space between the mesh structures 12 at different heights, so as to achieve ventilation control at different heights.

[0047] Optionally, the filler 11 is made of an airtight material, such as a rubber sealing agent, which has anti-corrosion, high-temperature resistance, and acid and alkali resistance. The filler 11 is fixedly installed on the inner wall of the outer pipe 10, and lubricating oil can be placed between the filler 11 and the outer wall of the inner pipe 18.

[0048] like Figure 3 As shown, taking a five-layer mesh structure 12 as an example, the mesh structure 12 itself can be ventilated. Each layer of mesh structure 12 can form a ventilation space without filling. That is, the thickness of a single mesh structure 12 is L1, and the pipe wall space corresponding to the thickness of L1 is hollow. Ventilation can be achieved through the first through hole 17, allowing air to ventilate outward from all mesh structures 12 at that height. From top to bottom, the pipe wall space at height L between the first layer of mesh structure 12 and the second layer of mesh structure 12 is filled with filling material 11, so the upper layer and the lower layer are not ventilated.

[0049] A further technical solution is that a support plate 12-1 is provided on at least one side of the mesh structure 12;

[0050] Optionally, the support plate 12-1 can be configured as a breathable structure, such as having ventilation holes on the plate surface.

[0051] A further technical solution is to improve the measurement effect of the sensing component 13. The size of the mesh structure 12 is larger than the area occupied by the sensing component 13. The size of the mesh structure 12 is determined according to the size of the sensing component 13 and the position of the mesh structure 12 on the linkage device 1.

[0052] Specifically, the area S of the outer surface of the mesh structure 12 is calculated using the following formula:

[0053]

[0054] Where n is a natural number, a set multiple, and can be set to n≥3; depth h is the height difference from the upper surface of the linkage device 1 to the corresponding mesh structure; S1 represents the area of ​​the contact surface between the sensing component 13 and the mesh structure 12; w is a set coefficient.

[0055] After determining the area of ​​the outer surface of the mesh structure 12 using this formula, the remaining dimensions are determined based on the specific shape of the mesh structure.

[0056] In this embodiment, the size of the mesh structure 12 is adaptively adjusted according to the embedment depth h of the linkage device 1. This ensures that the mesh structure 12 becomes smaller as the depth increases, thereby adapting to the pressure borne as the depth h increases and improving the durability of the device. At the same time, the size of the mesh structure 12 can ensure the air passage volume to meet the measurement needs of the sensing component 13.

[0057] In some embodiments, after the inner pipe 18 moves relative to the outer pipe 10, the mesh cover structure 12 communicates with the first through hole 17 at a set height. Specifically, the height difference of the first through hole 17 is not equal to the height difference of the mesh cover structure 12.

[0058] Specifically, the height difference of the first through hole 17 is H1, and the height difference of the mesh structure 12 is H2. H2 is greater than H1, so H3 = H2 - H1, which enables ventilation at one height while preventing ventilation at other heights.

[0059] Alternatively, the mesh structure 12 can be set with unequal height spacing, or the first through hole 17 can be set with unequal height spacing, such as increasing or decreasing the height spacing sequentially.

[0060] It is feasible to realize the relative movement of the inner pipe 18 with respect to the outer pipe 10. A driving device can be provided at one end of the inner pipe 18. The driving device can be an electric driving device, including a drive motor and a transmission device, and the transmission device is connected to the inner pipe.

[0061] Another possible implementation is that the drive device includes a spring 14 and a spring-rebound electromagnetic brake 15, with the spring 14 connected to the upper end of the inner pipe 18.

[0062] Spring-return electromagnetic brakes utilize electromagnetic force to generate braking force. The electromagnetic force causes the spring to deform or compress, thus activating the brake. When current passes through the electromagnet, the spring-return electromagnetic brake generates a magnetic field, attracting or releasing a mechanical component (such as a spring), thereby changing the brake's operating state.

[0063] Optionally, a ventilation device is connected to the upper end of the inner pipe. The ventilation device includes an air supply device and a ventilation duct. A ventilation duct 16 can be installed at the upper end of the inner pipe, and the ventilation device supplies gas to the ventilation duct 16 to achieve ventilation of the grain silo.

[0064] In use, the linkage device 1 is pre-embedded in the grain silo. The sensing components 13 at different heights can measure the carbon dioxide concentration, temperature, humidity and porosity of the grain at different locations. When the data detected by the sensing components 13 is abnormal, and the temperature, humidity and carbon dioxide concentration at a certain height of the grain pile are detected to be changing, making it unsuitable for grain storage, the control device 2 processes the collected grain silo environmental data to generate control over the ventilation drive device. The drive device is controlled to work, and the spring 14 is controlled to push the inner pipe 18 to the set position, so that the first through hole 17 and the corresponding mesh structure 12 are aligned, and ventilation is carried out at the corresponding height.

[0065] like Figure 2As shown, when the spring 14 is compressed to its maximum degree, gas can enter the uppermost (in the figure) first through hole 17; when the spring is compressed to its minimum degree, gas can enter the lowermost (in the figure) first through hole 17.

[0066] The device in this embodiment is fixed to the ground inside the grain silo via a connecting rod device 1, directly buried in the grain pile, achieving good stability and accuracy. It can simultaneously measure temperature, humidity, carbon dioxide concentration, and porosity at different heights, making measurements more convenient. In use, the device only needs to be pre-buried at the desired location within the grain silo. It accurately measures temperature, humidity, porosity, and carbon dioxide concentration at different heights within the grain silo without consuming significant manpower and resources, improving the efficiency of grain silo environmental monitoring and making it suitable for widespread use.

[0067] Example 2

[0068] Based on Embodiment 1, this embodiment provides a monitoring and adjustment method for a grain warehouse environment monitoring and adjustment device as described in Embodiment 1. This method can be implemented in a control device 2. The control device 2 processes the collected grain warehouse environment data to generate control over the ventilation drive device, including the following steps:

[0069] Step 1: Obtain environmental data inside the grain warehouse at different height locations;

[0070] Step 2: Based on the detected temperature, humidity, and carbon dioxide concentration, use interpolation methods to predict the temperature field, humidity field, and carbon dioxide distribution inside the grain silo.

[0071] Step 3: Based on the predicted temperature field, humidity field, and carbon dioxide distribution, determine the abnormal data locations as the locations to be ventilated, generate control commands, and perform ventilation control on the corresponding drive devices and ventilation devices.

[0072] In step 2, the interpolation method can be the Kriging interpolation method. Based on the data of the measured points, spatial autocorrelation is used to estimate the data values ​​of the unmeasured points, identify abnormal locations where the measured point data exceeds the threshold, and open the ventilation device at the height corresponding to the abnormal location to ventilate, so as to adjust the storage environment of the grain warehouse and ensure the storage effect of the grain.

[0073] In this embodiment, spatial interpolation prediction of grain silo environmental data is performed using the Kriging interpolation method to accurately estimate the temperature field, humidity field, and carbon dioxide concentration distribution. This effectively identifies the locations of data anomalies within the grain silo and precisely controls the activation of corresponding ventilation devices based on the height of the anomaly areas. This method can fully utilize data from a limited number of measurement points, improving the accuracy of perception of the grain silo environment. Compared to traditional methods based on fixed thresholds or uniform ventilation, this embodiment can more intelligently locate areas requiring ventilation, thereby achieving precise ventilation control, reducing unnecessary energy consumption, improving ventilation efficiency, optimizing the grain storage environment, reducing the risk of mold and pests, and ensuring the safety and quality stability of long-term grain storage.

[0074] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.

[0075] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
