[0002] Temperature and humidity are key factors affecting the quality of grain storage. Excessive temperature and humidity can cause grain to become moldy, sprout, and be infested with insects, while appropriate temperature and humidity can extend the storage period of grain and maintain its quality.

[0003] In the related art, the temperature and humidity control system of the granary is mostly a ventilation control system designed for small granaries.

However, such a temperature and humidity control system cannot quickly cool and dehumidify the grain, and the ventilation efficiency is low.

[0023] Reference to "one embodiment" or "some embodiments" or the like described in the specification of the present invention means that a particular feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present invention.

[0024] The following is combined with the accompanying drawings Figures 1 to 5 The warehouse temperature and humidity adjustment system provided by the present invention is described in detail.

[0025] See also Figure 1 The warehouse temperature and humidity adjustment system 100 in the embodiment of the present invention may include an atmosphere temperature and humidity detection device 101 , a warehouse temperature and humidity detection device 102 , a controller 103 and a movable air adjustment device 104 .

[0026] The movable air conditioning device 104 includes a plurality of movable ventilation components 106 distributed in a warehouse, and the warehouse includes storage stacks.

[0027] The atmospheric temperature and humidity detection device 101 can be used to detect a first temperature and a first humidity of the atmosphere.

[0028] The warehouse temperature and humidity detection device 102 can be used to detect the second temperature and second humidity of the air in the warehouse.

[0029] The ventilation component 106 can be used to detect the third temperature and the third humidity of the air in the storage stack, and can also be used to replace the air in the storage stack.

[0030] The controller 103 can be used to control the plurality of ventilation components 106 to replace the air in the storage stack based on the first temperature, the first humidity, the second temperature, the second humidity, the third temperature and the third humidity to adjust the temperature and humidity of the air in the storage stack.

[0031] In the embodiment of the present invention, the warehouse can be a large grain storage warehouse, that is, the warehouse temperature and humidity control system 100 provided in the embodiment of the present invention can be applied to a large storage warehouse, and the storage pile can be various grain piles. By detecting and comparing the temperature and humidity outside the warehouse, inside the warehouse, and inside the grain pile, it is determined whether the temperature and humidity of the grain pile need to be adjusted; through multiple ventilation components 106 distributed in the warehouse, accurate ventilation of the grain pile is achieved, thereby improving the ventilation efficiency of the grain pile and extending the storage time of the grain.

[0032] In some embodiments, Figure 2 As shown, the ventilation component 106 is tubular, and includes a temperature and humidity detection module 201, a plurality of air holes 202, and a first air replacement fan 203. The first air replacement fan 203 is provided at a vent at the top of the ventilation component 106, and the vent is higher than the storage pile, that is, the vent at the top of the ventilation component 106 connects the interior of the ventilation component 106 with the air of the warehouse.

[0033] It will be appreciated that in the absence of airflow, there will generally only be diffusion between the air in the warehouse, the air in the ventilation assembly 106, and the air in the storage stack.

[0034] The temperature and humidity detection module 201 can be used to detect a third temperature and a third humidity.

[0035] In this embodiment, each ventilation component 106 includes a temperature and humidity detection module 201, that is, each ventilation component 106 arranged in the warehouse can collect the temperature and humidity of the air at its location. For a certain area of ​​the storage pile, the temperature and humidity data collected by each ventilation component 106 in the area may be the same or different. The third temperature includes the temperature data collected by all ventilation components 106, and the third humidity includes the humidity data collected by all ventilation components 106.

[0036] The air hole 202 is used to connect the air inside the ventilation component 106 and the air inside the storage stack.

[0037] Furthermore, the temperature and humidity detection module 201 may include a plurality of detection units 204, and the detection unit 204 may be used to detect the fourth temperature and fourth humidity of the air at its location. It is understood that during the operation of the warehouse temperature and humidity control system 100, the ventilation component 106 is usually inserted into the storage pile, and its vent is ensured to be above the storage pile. Therefore, the fourth temperature and fourth humidity detected by the detection unit 204 are actually the temperature and humidity of the grain near its location.

[0038] like Figure 2 As shown. Multiple detection units 204 and air holes 202 are arranged at multiple preset heights of the ventilation component 106, multiple detection units 204 are arranged inside the ventilation component 106, and multiple air holes 202 are distributed on the tube wall of the ventilation component 106. Exemplarily, Figure 2 The ventilation component 106 shown in the figure includes 4 preset heights, and a plurality of air holes may be provided on the tube wall at each preset height of the ventilation component 106. For example, 4, 5 or 6 air holes may be evenly provided on the tube wall, and the actual number of air holes may be flexibly set according to the diameter of the ventilation component 106, and the present invention does not limit this.

[0039] It should be noted that, in actual applications, the length of the ventilation component 106 is designed according to the height of the storage pile. When determining the value of the above-mentioned preset height, the height of the storage pile should also be considered, and the specific setting can also be made in combination with the natural heat dissipation capacity of the actual storage pile. For example, the natural heat dissipation capacity of cereals, beans, and potato grains is different. For types with stronger heat dissipation capacity, the intervals between multiple preset heights can be the first interval, and for types with weaker heat dissipation capacity, the intervals between multiple preset heights can be the second interval, and the first interval is greater than the second interval. That is, for grain piles with weaker heat dissipation capacity, more levels of pores are set to fully improve the ventilation efficiency, so that the grains at the corresponding positions can be quickly cooled and dehumidified.

[0040] In this embodiment, the ventilation component 106 may also include a controllable closure member corresponding to the plurality of air holes 202, and the controllable closure member is used to control the opening or closing of the corresponding air hole 202. It can be understood that the opening and closing of each air hole 202 can be controlled. In practical applications, when the temperature of the air in the warehouse is lower than the temperature of the storage pile, the temperature of the grain on the surface of the storage pile is very close to the temperature of the air in the warehouse, but the temperature of the grain at the bottom of the storage pile may be higher. In this case, only the grain at the bottom needs to be ventilated, so only the air holes 202 at the bottom of the storage pile are opened, and the air holes 202 at the top of the storage pile can be set to a closed state.

[0041] Correspondingly, the ventilation component 106 in this embodiment further includes a first control module, and the first control module is electrically connected to the controller 103 .

[0042] The controller 103 may be specifically configured to determine a first instruction based on a first temperature, a first humidity, a second temperature, a second humidity, a plurality of fourth temperatures, and a plurality of fourth humidities. The first instruction includes an identifier of a target controllable closure, the target controllable closure being a controllable closure at a height of a target position in the storage stack; the target position being a position of the detection unit 204 corresponding to a fourth temperature greater than the first temperature or the second temperature, and a position of the detection unit 204 corresponding to a fourth humidity greater than the first humidity or the second humidity.

[0043] The first control module can be used to control the target controllable closure to open according to the first instruction, so that the corresponding air hole 202 is opened; at the same time, the first air replacement fan 203 of the target ventilation component 106 is controlled to open, so as to replace the air at the target position in the storage pile with the air inside the warehouse. The target ventilation component 106 is the ventilation component 106 where the controllable closure is located.

[0044] The first air replacement fan 203 can be used to blow the air in the warehouse from the ventilation port into the ventilation component 106, or to draw the air in the ventilation component 106 from the ventilation port into the air in the warehouse.

[0045] In one possible implementation, for locations in the storage stack that require ventilation, the air in the warehouse can be blown into the storage stack only through the ventilation components 106 near the location, that is, the first air replacement fans 203 of the corresponding ventilation components 106 are controlled to blow the air in the warehouse into these ventilation components 106.

[0046] In another possible implementation, for another position in the storage pile that needs ventilation, the air in the warehouse can be blown into the storage pile through a part of the ventilation assembly 106 near the other position, and the air in the storage pile can be drawn into the air in the warehouse through another part of the ventilation assembly 106 near the other position. That is, when low-temperature or low-humidity air is blown into a certain position in the storage pile, high-temperature or high-humidity air in the storage pile is simultaneously drawn out from a certain place near the position.

[0047] In the above embodiment, the opening and closing of the air holes 202 are controlled by controlling the controllable closing member. When a certain position of the storage stack needs to be ventilated, cooled or dehumidified, the corresponding air holes 202 of the ventilation components 106 near the position are opened first, and then the first air replacement fans 203 of these ventilation components 106 are turned on to blow air with lower temperature and humidity into the position in the storage stack, thereby achieving air replacement.

[0048] In some embodiments, the movable air conditioning device 104 in the present invention may further include a plurality of tracks, such as Figure 3As shown, the plurality of tracks include a plurality of rows of first tracks 301 , and a plurality of columns of second tracks 302 on each row of first tracks 301 .

[0049] The multiple columns of second rails 302 on each row of first rails 301 are parallel to each other and perpendicular to the first rails 301 in the horizontal direction; the multiple columns of second rails 302 on each row of first rails 301 are movably connected to the first rails 301. The controller 103 can be used to control the second rails 302 to move along the first rails 301 where they are located.

[0050] See also Figure 4 , the ventilation component 106 can be movably connected to the second track 302 through the movable support rod 401. The movable support rod 401 can be used to drive the ventilation component 106 to move in the horizontal direction along the second track 302, and can also be used to drive the ventilation component 106 to move in the horizontal direction along the vertical direction of the second track 302, and can also be used to drive the ventilation component 106 to move in the vertical direction. That is, through the first track 301, the second track 302 and the support rod 401, the ventilation component 106 can achieve three-dimensional movement.

[0051] In this embodiment, the controller 103 can also be used to control the ventilation component 106 in the first area to move to the vicinity of the first position and replace the air in the storage pile near the first position. The first position is a position in the storage pile where the temperature difference between the fourth temperature and the first temperature or the second temperature is higher than the preset temperature, or the humidity difference between the fourth humidity and the first humidity or the second humidity is higher than the preset humidity; the first area is an area of ​​preset size around the second position.

[0052] In some embodiments, the warehouse temperature and humidity control system 100 of the present invention may also include a warehouse replacement air system. Figure 5 The warehouse replacement air system includes a plurality of replacement air units 501 arranged on the walls of the warehouse.

[0053] Further, the replacement air unit 501 may include a switchable door, a second air replacement fan, and a humidity reducing device.

[0054] The switch door is used to control the opening and closing of the replacement air unit 501 , that is, to open or close the ventilation opening of the replacement air unit 501 .

[0055] The second air replacement fan is used to replace the air inside the warehouse. It can be understood that the air replacement method can be to blow air from the atmosphere into the warehouse, or to extract the air inside the warehouse into the atmosphere.

[0056] The humidity reducing device is used to reduce the humidity of the air entering the warehouse from the outside. For example, the humidity reducing device can be a controllable device with a drying function, or a controllable device with a desiccant. The present invention does not limit the type of the humidity reducing device.

[0057] In this embodiment, the warehouse air replacement system further includes a second control module, and the second control module is electrically connected to the controller 103 .

[0058] The controller 103 may also be configured to determine a second instruction based on the wind speed, the first temperature, the first humidity, the second temperature, the second humidity, the third temperature and the third humidity.

[0059] The second control module can be used to control the opening and closing of the door, the second air replacement fan, and the humidity reducing device according to the second instruction.

[0060] In the above embodiment, the warehouse replacement air system integrates multiple replacement air units 501 and a second control module, which can realize ventilation control between the inside and outside of the warehouse. Specifically, the controller 103 can calculate the temperature and humidity data to determine whether the air inside the warehouse needs to be adjusted. If adjustment is required, the control instruction (second instruction) can be sent to the second control module of the warehouse replacement air system. Afterwards, the second control module controls the opening and closing of the corresponding replacement air unit 501, the second air replacement fan, and the humidity reduction device according to the control instruction.

[0061] In some embodiments, the warehouse temperature and humidity control system 100 of the present invention may further include a wind measuring device, which is used to detect the wind speed outside the warehouse.

[0062] Specifically, the wind measuring device can be an anemometer, which is arranged outside the warehouse at a preset distance from the warehouse. The anemometer can detect not only wind speed but also wind direction.

[0063] Next, for several situations where air conditioning is required for storage stacks, the embodiment of the present invention provides a specific control method for the warehouse temperature and humidity conditioning system 100.

[0064] In some embodiments, the controller 103 may be specifically configured to: If the wind speed is less than or equal to the preset wind speed, When the first temperature, the second temperature, and the third temperature are equal, and the first humidity, the second humidity, and the third humidity are equal, the door, the second air replacement fan, and the humidity reduction device are controlled to be turned on to reduce the humidity of the air inside the warehouse; the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the third temperature is greater than the first temperature and the second temperature, or the third humidity is greater than the first humidity and the second humidity, the switch door is controlled to open, the second air replacement fan and the humidity reduction device are controlled to close, and the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the first temperature is lower than the second temperature and the third temperature, or the first humidity is lower than the second humidity and the third humidity, the switch door and the second air replacement fan are controlled to open, the humidity reduction device is controlled to close, and the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the second temperature is lower than the first temperature and the third temperature, or the second humidity is lower than the first humidity and the third humidity, the switch door, the second air replacement fan, and the humidity reduction device are controlled to be closed, and the multiple ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse.

[0065] In the above embodiment, under the premise that there is no wind outside or the wind speed outside cannot blow the outside air into the warehouse, the controller 103 needs to control the second air replacement fan in the replacement air unit 501 to open to ensure that the outside air and the air inside the warehouse can circulate quickly.

[0066] In some other embodiments, the controller 103 may be specifically used for: If the wind speed detected is greater than the preset wind speed, When the first temperature, the second temperature, and the third temperature are equal, and the first humidity, the second humidity, and the third humidity are equal, the door and the humidity reducing device are controlled to open to reduce the humidity of the air inside the warehouse; the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the third temperature is greater than the first temperature and the second temperature, or the third humidity is greater than the first humidity and the second humidity, the switch door is controlled to open, the second air replacement fan and the humidity reduction device are controlled to close, and the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the first temperature is lower than the second temperature and the third temperature, or the first humidity is lower than the second humidity and the third humidity, the switch door is controlled to open, the second air replacement fan and the humidity reduction device are controlled to close, and the plurality of ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse; When the second temperature is lower than the first temperature and the third temperature, or the second humidity is lower than the first humidity and the third humidity, the switch door, the second air replacement fan, and the humidity reduction device are controlled to be closed, and the multiple ventilation components 106 are controlled to replace the air in the storage stack with the air inside the warehouse.

[0067] In the above embodiment, under the premise that the outside wind speed can blow the outside air into the warehouse, the controller 103 will control the second air replacement fan in the replacement air unit 501 to be closed, and the outside air can naturally flow into the interior of the warehouse, while also achieving the effect of energy saving and consumption reduction.

[0068] When the temperature and humidity of the air in the storage pile and the air in the warehouse are the same and lower than the temperature and humidity of the outside air, the warehouse temperature and humidity adjustment system 100 does not need to adjust the air inside the warehouse. That is, the controller 103 is specifically used to control the door, the second air replacement fan, the humidity reduction device and the multiple ventilation components 106 to close when the third temperature and the second temperature are equal, the third humidity and the second humidity are equal, and the third temperature is lower than the first temperature and the third humidity is lower than the first humidity.

[0069] The embodiment of the present invention also provides the adjustment process of the warehouse temperature and humidity adjustment system 100 under 14 working conditions. The size relationship of the detection data corresponding to each working condition, as well as the working status of the door opening and closing, the second air replacement fan, the humidity reduction device, and the ventilation component 106 are shown in Table 1. In Table 1, the wind speed "N" indicates that the wind speed is less than or equal to the preset wind speed, and the wind speed "Y" indicates that the wind speed is greater than the preset wind speed; "ON" indicates the on state, and "OFF" indicates the off state; T1, T2, and T3 respectively represent the first temperature, the second temperature, and the third temperature; RH1, RH2, and RH3 respectively represent the first humidity, the second humidity, and the third humidity.

[0070] Table 1 The size of detection data corresponding to different working conditions and the working status of related devices

[0071] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 1, the temperature and humidity of the three locations (atmosphere, inside the warehouse, and storage pile) are equal, and the external wind force is insufficient. At this time, the switch door, the second air replacement fan, and the humidity reduction device are all in the open state. The second air replacement fan located on one side of the warehouse can blow the air outside the warehouse into the warehouse, and the air blown into the warehouse becomes low-humidity air after passing through the humidity reduction device. The second air replacement fan located on the other side of the warehouse can extract the air in the warehouse to the outside, thereby reducing the humidity of the air in the warehouse. At the same time, when the ventilation component 106 is turned on (the first air replacement fan is turned on and the pores are turned on), the low-humidity air entering the warehouse can also be blown into the storage pile, thereby replacing the original air in the storage pile with low-humidity air, achieving the effect of ventilating and dehumidifying the storage pile.

[0072] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 2, the temperature and humidity of the storage pile are relatively high. At this time, the switch door and the ventilation component 106 are in the open state, the second air replacement fan and the humidity reduction device are in the closed state, and the ventilation component 106 blows low-temperature and humid air into the storage pile to ventilate, cool and dehumidify the storage pile.

[0073] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 3, the temperature and humidity of the air inside the warehouse are relatively high, and the air inside the warehouse needs to be cooled and dehumidified. At this time, the switch door and the second air replacement device are in the open state, and the humidity reduction device and the ventilation component 106 are in the closed state. The second air replacement fan located on one side of the warehouse blows the air outside the warehouse into the warehouse, and the second air replacement fan located on the other side of the warehouse draws the air inside the warehouse to the outside, that is, the air outside the warehouse is used to replace the air inside the warehouse, thereby reducing the temperature and humidity of the air inside the warehouse.

[0074] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 4, the temperature and humidity of the air in the atmosphere are relatively high. At this time, there is no need to adjust the air inside the warehouse, so the door, the second air replacement fan, and the humidity reduction device are all in the closed state.

[0075] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 5, the temperature and humidity of the air in the atmosphere are relatively low. At this time, the switch door and the second air replacement device are in the open state, and the humidity reduction device is in the closed state, and the air with high temperature and humidity in the warehouse can be replaced with air with low temperature and humidity. At the same time, the ventilation component 106 is also in the open state, so as to replace the air in the storage pile with air with low temperature and humidity.

[0076] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 6, the temperature and humidity of the air in the storage pile are relatively low. At this time, there is no need to adjust the air in the storage pile, so the switch door, the second air replacement fan, and the humidity reduction device are all in the closed state.

[0077] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 7, the temperature and humidity of the air in the warehouse are relatively low. At this time, the switch door, the second air replacement device and the humidity reduction device are all in the closed state, and the ventilation component 106 is in the open state, so that the air inside the warehouse is blown into the storage pile to reduce the temperature and humidity of the storage pile.

[0078] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 8, the temperature and humidity of the three locations (atmosphere, inside the warehouse, and storage pile) are equal, and the external wind can blow air into the warehouse. At this time, the switch door and the humidity reduction device are both in the open state, and the second air replacement fan does not need to be turned on. The air on the windward side of the warehouse can be blown directly into the interior of the warehouse, and the air blown into the warehouse becomes low-humidity air after passing through the humidity reduction device. The air in the warehouse can enter the atmosphere through the vent of the replacement air unit 501 located on the leeward side of the warehouse, thereby reducing the humidity of the air in the warehouse. At the same time, when the ventilation component 106 is turned on, the low-humidity air entering the warehouse can also be blown into the storage pile, thereby replacing the original air in the storage pile with low-humidity air, achieving the effect of ventilating and dehumidifying the storage pile.

[0079] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 9, the temperature and humidity of the storage pile are relatively high, and the external wind can blow air into the warehouse. At this time, the switch door and the ventilation component 106 are in the open state, the second air replacement fan and the humidity reduction device are in the closed state, and the ventilation component 106 blows low-temperature and humid air into the storage pile to ventilate, cool and dehumidify the storage pile.

[0080] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 10, the temperature and humidity of the air inside the warehouse are relatively high, and the external wind can blow the air into the warehouse. At this time, the switch door is in the open state, and the second air replacement fan, the humidity reduction device and the ventilation component 106 are in the closed state. The air on the windward side of the warehouse can be directly blown into the interior of the warehouse, and the original air in the warehouse can enter the atmosphere through the vent of the replacement air unit 501 located on the leeward side of the warehouse, thereby reducing the humidity of the air in the warehouse.

[0081] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 11, the temperature and humidity of the air in the atmosphere are relatively high, and the external wind can blow the air into the warehouse. At this time, there is no need to adjust the air inside the warehouse, so the door, the second air replacement fan, and the humidity reduction device are all in a closed state.

[0082] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 12, the temperature and humidity of the air in the atmosphere are relatively low, and the external wind can blow the air into the warehouse. At this time, the switch door is in the open state, the second air replacement device and the humidity reduction device are in the closed state, and the air with high temperature and humidity in the warehouse can be replaced with air with low temperature and humidity. At the same time, the ventilation component 106 is also in the open state, so as to replace the air in the storage pile with air with low temperature and humidity.

[0083] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 13, the temperature and humidity of the air in the storage pile are relatively low. At this time, there is no need to adjust the air in the storage pile, so the switch door, the second air replacement fan, and the humidity reduction device are all in the closed state.

[0084] As shown in Table 1, when the warehouse temperature and humidity control system 100 is in working condition 14, the temperature and humidity of the air in the warehouse are relatively low. At this time, the switch door, the second air replacement device and the humidity reduction device are all in the closed state, and the ventilation component 106 is in the open state, so that the air inside the warehouse is blown into the storage pile to reduce the temperature and humidity of the storage pile.

[0085] The warehouse temperature and humidity control system 100 provided in the embodiment of the present invention can determine whether the air in the storage pile needs to be replaced by detecting the temperature and humidity of the air outside the warehouse, inside the warehouse, and in the storage pile, and can also determine whether the air in the warehouse needs to be replaced. The air in the storage pile is replaced by multiple ventilation components 106 distributed inside the warehouse, so that the interior of the storage pile is ventilated in time; the air in the warehouse is replaced by multiple replacement air units 501. Moreover, the ventilation component 106 can move in three dimensions, and can quickly and accurately adjust the ventilation at the designated position of the storage pile, improve the cooling and dehumidification efficiency of the storage pile in the warehouse, and effectively extend the storage time of the stored objects.
