Description

Technical Field

[0001] The present disclosure relates to the technical field of grain bin environment monitoring. Specifically, it relates to a grain bin environment monitoring and regulating device and method. Background Art

[0002] The statements in this section merely provide background technical information related to the present disclosure and do not necessarily constitute prior art.

[0003] As an important strategic material, the storage safety of grain is of crucial importance. As a key place for grain storage, the internal environmental conditions of the grain bin have a decisive impact on the quality and storage period of grain. Factors such as temperature and humidity, porosity, and carbon dioxide concentration, if not effectively monitored and regulated, will directly affect the storage effect and long-term safety of grain. With the increasing demand for grain storage, the environmental monitoring of grain bins has become increasingly important. Therefore, accurately monitoring and adjusting various environmental parameters in the grain bin has become a key step in ensuring grain storage safety.

[0004] In the process of grain bin environment monitoring, traditional grain bin monitoring devices have certain limitations. Existing monitoring methods and equipment generally have problems such as insufficient monitoring accuracy and low intelligence. Specifically, traditional environmental monitoring devices generally require multiple sensors to be installed in the bin, and it is difficult to adjust the sensor positions in real time to adapt to environmental changes at different positions. Currently, the grain bin temperature and humidity monitoring devices can often only collect data from certain areas in the grain bin and cannot achieve comprehensive monitoring of the entire grain bin space. Therefore, it is impossible to accurately grasp the temperature and humidity changes in different areas and also impossible to understand the distribution of carbon dioxide concentration in the grain bin in real time. At the same time, when existing devices detect problems, they usually cannot effectively regulate the grain bin environment. This results in the inability to take corresponding adjustment measures in a timely manner when the temperature and humidity, carbon dioxide concentration, etc. in the grain bin are abnormal, which may further affect the preservation effect of grain. Especially in large-scale grain bins, once an environmental anomaly occurs, relying on manual adjustment of grain storage is not only extremely labor-intensive but also inefficient, and it is difficult to ensure the stability and safety of grain storage. Summary of the Invention

[0005] To solve the above problems, the present disclosure proposes a grain bin environment monitoring and regulating device and method, and proposes a plug-and-play embedded device that can achieve comprehensive monitoring of the environment at different depths in the grain bin. At the same time, when a problem is detected in the storage environment, it can ventilate and regulate the area at the corresponding height, realizing unattended and automated grain storage monitoring.

[0006] To achieve the above object, the present disclosure adopts the following technical solutions:

[0007] One or more embodiments provide a device for monitoring and regulating the environment of a granary, including a connecting rod device and a control device; the connecting rod device includes an inner pipe and an outer pipe which are nested inside and outside each other;

[0008] Inside the pipe wall space formed by the inner pipe and the outer pipe, a sensing component is sequentially arranged from top to bottom;

[0009] The area on the outer pipe corresponding to the sensing component is set as a mesh structure to form a channel for gas to flow to the sensing component;

[0010] The inner pipe is movably arranged inside the outer pipe, and a first through hole is arranged 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, realizing the air circulation from inside the inner pipe to outside the outer pipe.

[0011] One or more embodiments provide a monitoring and regulating method for the above-mentioned device for monitoring and regulating the environment of a granary, including the following steps:

[0012] Obtain the environmental data inside the granary at different detected positions;

[0013] According to the detected temperature, humidity and carbon dioxide concentration, use the interpolation method to predict the temperature field, humidity field and carbon dioxide distribution inside the granary;

[0014] According to the predicted temperature field, humidity field and carbon dioxide distribution, determine the position with abnormal data as the position to be ventilated, generate a control instruction, and perform ventilation control on the corresponding driving device and ventilation device.

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

[0016] The nested design of the inner pipe and the outer pipe of the present disclosure helps to improve the structural stability of the device and can reduce the interference of external factors on the sensor. The sensing components are sequentially arranged from top to bottom along the pipe wall space between the inner and outer pipes, enabling multi-point monitoring of the granary environment at different heights. The area on the outer pipe corresponding to the sensing component is set as a mesh structure, and the gas in the grain can diffuse to the sensing component through the mesh structure on the mesh cover. At the same time, the mesh structure can effectively prevent large particulate matter from entering the pipe, ensure the cleanliness of the working environment of the sensor, reduce the influence of impurities on the accuracy of the sensor, and extend the service life of the sensor; the relative movement of the inner and outer pipe walls can be adjusted to achieve ventilation at different upper and lower height positions, ensuring that gas can smoothly flow into the detection area of the granary when needed, thereby realizing the monitoring and ventilation regulation of the granary environment.

[0030] Example 1

[0031] In the technical solutions disclosed in one or more embodiments, as Figures 1 to 4 shown, a grain bin environment monitoring and regulating device includes a connecting rod device 1 and a control device 2. The connecting rod device 1 includes an inner pipe 18 and an outer pipe 10 which are nested inside and outside each other; a sensing assembly 13 is successively arranged from top to bottom in the pipe wall space formed by the inner pipe 18 and the outer pipe 10;

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

[0033] The inner pipe 18 is movably arranged inside the outer pipe 10. A first through hole 17 is arranged 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, realizing the air flow from inside the inner pipe 18 to outside the outer pipe 10.

[0034] In this embodiment, the nested design of the inner pipe 18 and the outer pipe 10 helps to improve the structural stability of the device and can reduce the interference of external factors on the sensor. The sensing assembly 13 is successively arranged from top to bottom along the pipe wall space of the inner and outer pipes 10, and can perform multi-point monitoring of the environment of the grain bin at different heights. The area of the outer pipe 10 corresponding to the sensing assembly 13 is set as a mesh structure 12. The gas in the grain can diffuse to the sensing assembly 13 through the mesh hole structure on the mesh. At the same time, the mesh structure 12 can effectively prevent large-particle substances from entering the pipe, ensure the cleanliness of the working environment of the sensor, reduce the influence of impurities on the accuracy of the sensor, and extend the service life of the sensor; the inner and outer pipe walls can move relative to each other, and the ventilation at different heights up and down can be adjusted to ensure that gas can smoothly flow into the detection area of the grain bin when needed, thereby realizing the monitoring and ventilation regulation of the grain bin environment.

[0035] When in use, the connecting rod device 1 of this device is buried in the grain bin to be measured, and the environmental parameters of the grain bin, including temperature and humidity, porosity, and carbon dioxide content, can be predicted. At the same time, ventilation can be performed according to the monitoring results to ensure the preservation effect of the grain.

[0036] In some embodiments, the sensing assembly 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 barometric pressure sensor, and the change of porosity is reflected according to the change of barometric pressure;

[0038] The transmission line of the sensing component is connected to the signal acquisition device arranged on the upper end surface of the connecting rod device 1 through the pipe wall space, and 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 of the outer pipe 10 corresponding to the sensing component 13 is set as a mesh structure 12. Specifically, the outer pipe 10 is provided with an opening of a set size, and the mesh structure 12 is fixed at the opening and extends inward by a set depth, so that the inner surface of the mesh structure 12 is spaced 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 arranged on the inner surface of the mesh structure 12;

[0040] Preferably, after the sensing component 13 is arranged on the inner surface of the mesh structure 12, it is spaced from the outer surface of the inner pipe 18 by a set distance.

[0041] The mesh structure 12 of this embodiment is a three-dimensional structure with a certain thickness. Optionally, the mesh structure can be set as a structure of multiple layers of meshes stacked, or the mesh structure 12 is a honeycomb-like structure;

[0042] Optionally, the mesh structure 12 is set as a sector.

[0043] In a further technical solution, one or more sensing components can be arranged at the same height of the sensing component 13, and each sensing component is arranged at the pipe wall opening on the outer pipe 10 through the mesh structure 12, and a first interval space 10-1 is formed between the mesh structures 12 at the same height;

[0044] Optionally, when a group of sensing components 13 are arranged at the same height, one or the mesh structure 12 is arranged at the same height position, and the mesh structures 12 at the same height are spaced to form a first interval space 10-1; as Figure 4 shown, it is a cross-sectional structure diagram when one sensing component 13 is arranged on the same layer, and at the same time, multiple mesh structures 12 are arranged at the plane height to improve the ventilation effect.

[0045] During use, air can be introduced into the inner pipe 18 and passed through the mesh structure 12 to ventilate to the outside of the outer pipe 10, so as to adjust the grain storage environment, such as realizing cooling, etc., to ensure the grain storage effect.

[0046] In some embodiments, to improve the stability and durability of the device and achieve ventilation control at different heights, fillers 11 are arranged in the pipe wall space between the mesh structures 12 at different heights to enable ventilation control at different heights.

[0047] Optionally, the filler 11 is made of an airtight material, which can be a rubber sealing substance with the properties of corrosion resistance, high temperature resistance, and acid and alkali resistance. The filler 11 is fixedly arranged on the inner wall of the outer pipe 10, and lubricating oil can be provided between the filler 11 and the outer wall of the inner pipe 18;

[0048] As Figure 3 shown, taking the case where a five-layer mesh structure 12 is provided as an example, the mesh structure 12 itself can achieve ventilation. An air ventilation space can be formed between each layer of the mesh structure 12, and no filler is provided. That is, if the thickness of a single mesh structure 12 is L1, the pipe wall space corresponding to the L1 thickness is hollow, and ventilation can be carried out outward from all the mesh structures 12 at this height through the first through hole 17; from top to bottom, there is a filler 11 in the pipe wall space with a height of L between the first layer of the mesh structure 12 and the second layer of the mesh structure 12, so that the upper layer and the lower layer are not ventilated.

[0049] In a further technical solution, 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 set to a breathable structure, such as providing ventilation holes on the plate surface.

[0051] In a further technical solution, 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, and 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 connecting rod device 1;

[0052] Specifically, for the area S of the outer surface of the mesh structure 12, the calculation formula is:

[0053]

[0054] where n is a natural number, which is a set multiple, and it can be set that n≥3; the depth h is the height difference between the upper surface of the connecting rod device 1 and 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 size of the outer surface of the mesh structure 12 through this formula, the remaining dimensions are determined according to the specific shape of the mesh structure.

[0056] In this embodiment, the size is adaptively adjusted according to the burial depth h of the mesh structure of the connecting rod device 1, which can ensure that as the depth increases, the mesh structure 12 becomes smaller, so as to adapt to the pressure borne as the depth h increases and improve the durability of the device. At the same time, the size of the mesh structure 12 can ensure the ventilation 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 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 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 can achieve ventilation at one height, while no ventilation at other heights;

[0059] Alternatively, the mesh structure 12 may be arranged at unequal height intervals, or the first through holes 17 may be arranged at unequal height intervals, such as the height intervals may increase or decrease in sequence.

[0060] It is feasible that, in order to realize the relative movement of the inner pipe 18 relative to the outer pipe 10, a driving device may be provided at one end of the inner pipe 18, and the driving device may be an electric driving device, including a driving motor and a transmission device, and the transmission device is connected to the inner pipe;

[0061] In another achievable implementation, the driving device includes a spring 14 and a spring-rebound electromagnetic brake 15 , and the spring 14 is connected to the upper end of the inner pipe 18 .

[0062] Spring rebound electromagnetic brakes use electromagnetic force to generate braking force, and the spring is deformed or compressed by the electromagnetic force, so that the brake works. When current passes through the electromagnet, the spring rebound electromagnetic brake will generate a magnetic field, attracting or releasing a mechanical component (such as a spring), thereby changing the working state of the brake.

[0063] Optionally, a ventilation device is connected to the upper end of the inner pipe, and the ventilation device includes an air source providing device and a ventilation duct; a ventilation duct 16 can be set at the upper end of the inner pipe, and the ventilation device transports gas to the ventilation duct 16 to achieve ventilation of the granary.

[0064] When in use, the connecting rod device 1 is pre-buried in the granary, and the sensor components 13 at different heights can measure different positions to obtain the carbon dioxide concentration, temperature and humidity and porosity of the grain at different positions. When the data detected by the sensor component 13 is abnormal, the temperature and humidity at a certain height of the grain pile are monitored, and the carbon dioxide concentration changes, which is not suitable for grain storage, the control device 2 processes the collected granary environment data, thereby generating a control for the driving device for achieving ventilation, controlling the driving device to work, and controlling the spring 14 to push the inner pipe 18 to the set position, so that the first through hole 17 and the relative mesh cover structure 12 are aligned, and ventilation is performed at the corresponding height;

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

[0066] The device of this embodiment is fixed to the ground inside the granary through the connecting rod device 1 and is directly buried in the grain pile, which can achieve better stability and accuracy. At the same time, it can measure the temperature, humidity, carbon dioxide concentration, and porosity at different heights, making the measurement more convenient. When in use, only need to pre-bury this device at the position of the granary to be measured. Without consuming a large amount of manpower and material resources, it can accurately measure the temperature, humidity, porosity, and carbon dioxide concentration at different heights of the granary, improving the efficiency of the granary environment monitoring process and being suitable for extensive promotion and use.

[0067] Embodiment 2

[0068] Based on Embodiment 1, in this embodiment, a monitoring and adjustment device method for a granary environment monitoring and adjustment device described in Embodiment 1 is provided, which can be implemented in the control device 2. The control device 2 processes the collected granary environment data to generate a control for the driving device for ventilation, including the following steps:

[0069] Step 1: Obtain the environmental data inside the granary at different height positions detected.

[0070] Step 2: According to the detected temperature, humidity, and carbon dioxide concentration, use the interpolation method to predict the temperature field, humidity field, and carbon dioxide distribution inside the granary.

[0071] Step 3: According to the predicted temperature field, humidity field, and carbon dioxide distribution, determine the data abnormal position as the position to be ventilated, generate a control instruction, and perform ventilation control on the corresponding driving device and ventilation device.

[0072] In Step 2, the interpolation method can adopt the Kriging interpolation method. Based on the data of the measured points, use the spatial autocorrelation to estimate the data values of the unmeasured points, identify the abnormal positions where the measured point data exceeds the threshold, open the ventilation device at the height corresponding to the abnormal position, and perform ventilation to adjust the storage environment of the granary and ensure the storage effect of the grain.

[0073] In this embodiment, spatial interpolation prediction of the grain bin environmental data is carried out based on the Kriging interpolation method to achieve accurate estimation of the temperature field, humidity field and carbon dioxide concentration distribution, effectively identify the positions of abnormal internal data of the grain bin, and accurately control the corresponding ventilation devices to start ventilation according to the height of the abnormal area. This method can make full use of the data of limited measurement points, improve the perception accuracy of the grain bin environmental state. Compared with the traditional methods based on fixed thresholds or uniform ventilation, this embodiment can more intelligently locate the areas that need ventilation, so as to achieve precise ventilation control, reduce unnecessary energy consumption, improve ventilation efficiency, optimize the grain storage environment, reduce the risks of mildew and pests, and ensure the safety and quality stability of long-term grain storage.

[0074] The above are only the preferred embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.

[0075] Although the specific implementation manners of the present disclosure have been described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present disclosure. Those skilled in the art should understand that based on the technical solutions of the present disclosure, various modifications or deformations that can be made without creative efforts by those skilled in the art are still within the protection scope of the present disclosure.
