[0002] Currently, when storing fruits and vegetables, these items undergo chemical reactions that produce gases such as ethylene, acetaldehyde, and ethanol. When the concentration of these gases reaches a certain level, it accelerates the deterioration of the items and shortens their shelf life.
[0003] For example, when storing fruits and vegetables in cold storage or refrigerators, the current practice usually only regulates the temperature of the storage space, i.e., only refrigeration, without considering the regulation of the concentration of various gases in the storage space. As a result, the shelf life of the stored items is relatively short. Summary of the Invention
[0004] In view of this, in order to solve some or all of the above-mentioned technical problems, embodiments of this application provide a method, system, device, control equipment, and computer-readable storage medium for adjusting the gas concentration in a room.
[0005] In a first aspect, embodiments of this application provide a method for adjusting the gas concentration in a room. The method includes: acquiring the target gas concentration detected by a gas concentration detection device installed in the target room; determining whether the target gas concentration reaches a preset threshold; if the preset threshold is reached, determining the target concentration level corresponding to the target gas concentration; based on the target concentration level, controlling an air intake device connected to the target room via a pipeline to perform an air intake operation, and controlling the air intake rate of the air intake device to adjust to the target air intake rate corresponding to the target concentration level.
[0006] In one possible implementation, controlling the intake rate of the intake device to adjust to the target intake rate corresponding to the target concentration level includes: adjusting the position of the intake valve plate included in the intake device to the target position corresponding to the target concentration level, so that the intake rate of the intake device reaches the target intake rate, wherein the position of the intake valve plate is used to control the opening size of the intake port of the intake device.

The pressure detection device is installed in the target room, and the pressure balancing device is communicatively connected to the control device. The pressure balancing device is connected to the second air inlet of the target room via a pipe. The pressure detection device is used to detect the indoor air pressure in the target room. The control device is also used to determine whether the indoor air pressure is consistent with the outdoor air pressure outside the target room. If they are inconsistent, a ventilation start command is sent to the pressure balancing device. The pressure balancing device is used to perform a ventilation operation according to the ventilation start command to make the indoor and outdoor air pressures in the target room tend to be consistent. The control device is also used to send a ventilation stop command to the pressure balancing device in response to determining that the re-detected indoor air pressure is consistent with the outdoor air pressure.

[0038] To address the technical problem of shortened shelf life caused by the generation of harmful gases when storing fruits and vegetables in storage rooms, this application provides a method for adjusting gas concentration in storage rooms. This method can deliver a specific type of gas to the target storage room when the concentration of harmful gases in the target storage room is high, thereby extending the shelf life of the items.
[0039] Figure 1This is a flowchart illustrating a method for regulating gas concentration in a room, as provided in an embodiment of this application. This method can be applied to control devices, which can be of various types, such as a single control chip, a circuit board containing a control chip, or one or more dedicated control devices, or a smartphone, laptop, desktop computer, portable computer, server, or other general-purpose control device. Furthermore, the execution entity of this method can be hardware or software. When the execution entity is hardware, it can be one or more of the aforementioned control devices. For example, a single control device can execute this method, or multiple control devices can cooperate with each other to execute this method. When the execution entity is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are made here.
[0040] like Figure 1 As shown, the method specifically includes:
[0041] Step 101: Obtain the target gas concentration detected by the gas concentration detection device installed in the target room.
[0042] In this embodiment, the target room can be any type of room used for storing items. For example, it can be a space used for storing items, such as a cold storage, refrigerator, or freezer. Items stored in the target room often produce specific types of gases, which affect the shelf life of the items. For example, the target room may store fruits and vegetables, which produce harmful gases such as ethylene, acetaldehyde, and ethanol. If these harmful gases reach a certain concentration, they will shorten the shelf life of the fruits and vegetables.
[0043] The aforementioned gas concentration detection device is used to detect specific types of gases, such as online gas analyzers. The target gas concentration is the concentration of the target type of gas produced by the aforementioned item.
[0044] The gas concentration detection device can detect the concentration of a target gas in real time or at regular intervals. For example, a shelf life can be set in the control device; if the shelf life is reached at the current time, the method is executed. The detected target gas concentration can be sent to the control device.
[0045] Step 102: Determine whether the target gas concentration has reached the preset threshold.
[0046] In this embodiment, the preset threshold is a gas concentration value pre-set in the control device. When the target gas concentration reaches the preset threshold, it indicates that the concentration of harmful gas has already affected the preservation of the items, and the concentration of harmful gas in the target room needs to be adjusted.
[0047] Step 103: If the preset threshold is reached, determine the target concentration level corresponding to the target gas concentration.
[0048] In this embodiment, the correspondence between gas concentration and concentration level can be preset. For example, three concentration levels can be set: low hazard, medium hazard, and high hazard. Let the preset threshold be A1, meaning that when the target gas concentration is less than A1, the gas concentration is harmless, and no gas intake operation is required. When the target gas concentration is greater than or equal to A1 and less than A2, the concentration level is low hazard; when the target gas concentration is greater than or equal to A2 and less than A3, the concentration level is medium hazard; and when the target gas concentration is greater than or equal to A3, the concentration level is high hazard.
[0049] Step 104: Based on the target concentration level, control the air intake device connected to the target compartment via a pipeline to perform air intake operation, and control the air intake rate of the air intake device to adjust to the target air intake rate corresponding to the target concentration level.
[0050] In this embodiment, the air intake device can be installed inside or outside the target room. The air intake device is connected to the target room via a pipe, thereby supplying gas to the target room through the pipe. The air intake device can supply a specific type of gas to the target room; typically, the supplied gas is beneficial for storing items within the target room. For example, when the items stored in the target room include fruits and vegetables, a mixture of oxygen and carbon dioxide can be supplied to the target room.
[0051] The control equipment can generate a corresponding intake rate control signal based on the target concentration level and send the intake rate control signal to the intake device. The intake device adjusts the intake rate according to the intake rate control signal; generally, the higher the target gas concentration, the faster the intake rate.
[0052] As an example, the air intake device may include a fan, which adjusts the air intake rate by adjusting the fan speed according to the air intake rate control signal.
[0053] Typically, after the air intake device delivers gas to the target compartment, the concentration of the aforementioned harmful gases will gradually decrease, thereby extending the shelf life.
[0054] The gas concentration regulation method for a storage room provided in this application involves detecting the target gas concentration using a gas concentration detection device installed in the target storage room. When the target gas concentration reaches a preset threshold, a target concentration level is determined. Based on this target concentration level, an air intake device installed in the target storage room is controlled to deliver a specific type of gas to the target storage room at a target air intake rate. This achieves automated and targeted regulation of the concentration of harmful target gases in the target storage room, thereby helping to reduce the impact of gases generated by stored items on item quality and extending the shelf life of the items. Furthermore, it reduces the degree of manual intervention in monitoring the quality of stored items, improving the efficiency of item quality control.
[0055] In some optional implementations of this embodiment, step 104 includes:
[0056] Adjust the intake valve plate of the intake device to the target setting corresponding to the target concentration level so that the intake rate of the intake device reaches the target intake rate.
[0057] The position of the intake valve plate is used to control the opening size of the intake port of the intake device.
[0058] The correspondence between the intake device's settings and concentration levels can be preset. For example, the intake device may have three settings: C1, C2, and C3. Setting C1 corresponds to the smallest inlet opening, setting C3 to the largest, and setting C2 to a moderate opening. These three settings correspond to the low-hazard, medium-hazard, and high-hazard concentration levels, respectively. If the target concentration level is low-hazard, the target setting is C1. The intake opening is adjusted to correspond to setting C1, allowing the gas to enter the target room at a low speed.
[0059] This embodiment adjusts the intake rate by adjusting the intake valve plate of the intake device, achieving precise control of the intake rate. This helps to deliver the appropriate amount of gas to the target compartment more accurately, avoiding gas waste. At the same time, it precisely controls the reduction of the concentration of harmful gases in the target compartment, thereby helping to reduce the risk of spoilage of the items in the target compartment.
[0060] In some optional implementations of this embodiment, after step 104, the method further includes:
[0061] Extend the shelf life of the target items in the target room by a preset time and save the extended shelf life.
[0062] The target items mentioned above can be specific types of items stored in the target room, such as fruits and vegetables. These items have a relatively short shelf life and are prone to generating specific gases during storage, affecting their shelf life. Therefore, it is necessary to record the shelf life. Typically, the method provided in this embodiment can be executed after the current shelf life is reached. That is, after the shelf life is reached, gas concentration is detected, the air intake rate of the air intake device is adjusted according to the detection results, and then the shelf life is extended. When the next shelf life is reached, this method is repeated.
[0063] Optionally, if the detected concentration of the target gas exceeds the preset upper limit after the shelf life has expired, the shelf life will not be extended, and a warning message can be issued to the user.
[0064] This embodiment extends the shelf life of items stored in the target compartment by supplying gas to the target compartment, thus enabling precise adjustment of the shelf life. This helps reduce manual intervention in monitoring the quality of stored items and saves labor costs.
[0065] In some optional implementations of this embodiment, after step 104, the method further includes:
[0066] In response to the re-detection of a target gas concentration that is less than or equal to a preset threshold, the air intake device is controlled to stop the air intake operation.
[0067] Specifically, the aforementioned gas concentration detection device can detect the target gas concentration in real time. If the target gas concentration drops below a preset threshold after gas is supplied to the target chamber, the control device can send a stop-intake control signal to the intake device. The intake device can then stop supplying gas to the target chamber based on the stop-intake control signal. For example, the intake valve of the aforementioned ventilation device can be adjusted to the closed state.
[0068] This embodiment can effectively save the amount of gas delivered and avoid other problems caused by excessive gas delivery by stopping the delivery of gas to the target chamber when the target gas concentration is detected to be less than or equal to a preset threshold.
[0069] In some optional implementations of this embodiment, such as Figure 2 As shown, the method also includes:
[0070] Step 201: Obtain the indoor air pressure detected by the air pressure detection device installed in the target room.
[0071] Among them, the air pressure detection device can detect the air pressure of the target chamber in real time and send the detection results to the control equipment.
[0072] Step 202: Determine whether the indoor air pressure is consistent with the outdoor air pressure outside the target room.
[0073] The outdoor air pressure can be a preset fixed air pressure value, or it can be the air pressure value detected by another air pressure detection device located outside the target room.
[0074] Optionally, the indoor and outdoor air pressures can be determined to be consistent when they are exactly equal, or when the absolute value of the difference between the indoor and outdoor air pressures is less than or equal to a preset value.
[0075] Step 203: If the indoor air pressure is inconsistent with the outdoor air pressure, control the air pressure balancing device connected to the target room through a pipe to perform an air exchange operation.
[0076] The pressure balancing device can be installed inside or outside the target room. It is connected to the target room via pipes to facilitate gas exchange between the target room and the outside environment.
[0077] Optionally, when the indoor air pressure is lower than the outdoor air pressure, a first control signal can be sent to the air pressure balancing device. The air pressure balancing device, based on the first control signal, delivers the outdoor air of the target room into the target room, thereby increasing the indoor air pressure.
[0078] When the indoor air pressure is greater than the outdoor air pressure, a second control signal can be sent to the air pressure balancing device. The air pressure balancing device will discharge the air in the target room according to the second control signal, thereby reducing the indoor air pressure.
[0079] Step 204: In response to determining that the re-detected indoor air pressure is consistent with the outdoor air pressure, the air pressure balancing device is controlled to stop the ventilation operation.
[0080] Specifically, during the ventilation operation performed by the air pressure balancing device, the air pressure detection device can continue to detect the air pressure in the target room in real time. If the indoor air pressure obtained by the control device from the air pressure detection device is consistent with the outdoor air pressure, it sends a ventilation end control signal to the air pressure balancing device, and the air pressure balancing device stops performing the ventilation operation.
[0081] This embodiment, by setting up an air pressure detection device and an air pressure balancing device, enables timely adjustment of the air pressure in the target room when the indoor and outdoor air pressures are inconsistent, so that the indoor and outdoor air pressures are kept consistent. This avoids the problem of the door being unable to be opened or closed due to uneven force on both sides of the door caused by the inconsistent indoor and outdoor air pressures.
[0082] Figure 3This is a schematic diagram of a gas concentration regulation system 300 in a room provided in an embodiment of this application. Specifically, it includes: a target room 301 for storing target items, a control device 302, a gas storage device 303, an air intake device 304, and a gas concentration detection device 305.
[0083] The air intake device 304 and the gas storage device 303 are connected by a pipe. The air intake device 304 is connected to the first air inlet of the target chamber 301 by a pipe. The gas concentration detection device 305 is installed in the target chamber 301. The control device 302 is communicatively connected to the air intake device 304 and the gas concentration detection device 305.
[0084] The aforementioned target compartment 301 can be any type of compartment used for storing target items. For example, it can be a space used for storing items in a cold storage, refrigerator, or freezer. The target items stored in the target compartment 301 typically produce specific types of gases that affect the shelf life of the items. For example, target items may include fruits and vegetables, which produce harmful gases such as ethylene, acetaldehyde, and ethanol. If these harmful gases reach a certain concentration, they will shorten the shelf life of the fruits and vegetables.
[0085] The gas concentration detection device 305 is used to detect the concentration of the target gas in the target chamber 301. The target gas concentration is the concentration of the target type of gas produced by the target item. The gas concentration detection device 305 is a device used to detect a specific type of gas, such as an online gas analyzer.
[0086] The aforementioned gas storage device 303 may include a gas storage tank containing a gas that can slow down the deterioration of the target item. For example, it may be a mixture of carbon dioxide and oxygen.
[0087] The aforementioned air intake device 304 can be installed inside the target compartment 301. Figure 3 The air intake device 304 shown can be located inside the target chamber 301 or outside the target chamber 301. The air intake device 304 is connected to the gas storage device 303 via a pipe. The air intake device 304 may include a controlled component that can adjust the rate at which the gas is delivered to the target chamber 301 according to a received control signal.
[0088] Optionally, the intake device 304 may include an intake valve plate, which is adjusted to a corresponding position under the control of a control signal, thereby adjusting the intake rate.
[0089] The aforementioned air intake device 304 and gas concentration detection device 305 can be connected to the control device 302 via wired or wireless means. Optionally, the control device 302 can be connected to the air intake device 304 and gas concentration detection device 305 via a network, thereby realizing the functions of remotely monitoring gas concentration and remotely controlling the air intake rate.
[0090] The control device 302 described above is used to execute the above-described method for regulating the gas concentration in the room. The control device 302 can be of various types, such as a separate control chip, a circuit board containing a control chip, or one or more dedicated control devices 302, or it can be on one or more general-purpose control devices 302 such as smartphones, laptops, desktop computers, portable computers, servers, etc.
[0091] The aforementioned air intake device 304 is used to deliver gas from the gas storage device 303 to the target chamber 301 under the control of the control device 302. Specifically, the control device 302 generates a control signal corresponding to the target concentration level by executing the aforementioned gas concentration adjustment method, and sends this control signal to the air intake device 304. The air intake device 304 adjusts to the corresponding target air intake rate according to the control signal, delivering the gas from the gas storage device 303 to the target chamber 301.
[0092] Optionally, when the target gas concentration in the target chamber 301 drops below a preset threshold, the control device 302 may send a stop-intake control signal to the intake device 304. The intake device 304 may then stop supplying gas to the target chamber 301 based on the stop-intake control signal. For example, the intake valve of the aforementioned ventilation device may be adjusted to the closed state.
[0093] The gas concentration regulation system for a storage compartment provided in this application involves setting up a target compartment, control equipment, a gas storage device, an air intake device, and a gas concentration detection device. The gas concentration detection device in the target compartment detects the target gas concentration. Based on the target concentration level corresponding to the target gas concentration, the control equipment controls the air intake device in the target compartment to deliver a specific type of gas to the target compartment at a target intake rate. This achieves automated and targeted regulation of the concentration of harmful target gases in the target compartment, thereby helping to reduce the impact of gases generated by stored items on the quality of the items and extending their shelf life. Furthermore, it reduces the degree of manual intervention in monitoring the quality of stored items, improving the efficiency of quality control.
[0094] In some optional implementations of this embodiment, such as Figure 4 As shown, the system also includes a pressure detection device 306 and a pressure balancing device 307.
[0095] The air pressure detection device is installed in the target chamber 301, the air pressure balancing device is connected to the control device 302, and the air pressure balancing device is connected to the second air inlet of the target chamber 301 through a pipeline.
[0096] The air pressure detection device is used to detect the indoor air pressure of the target room 301. The air pressure detection device can be any type of device used to detect air pressure, such as an online air pressure detector.
[0097] The control device 302 is also used to determine whether the indoor air pressure is consistent with the outdoor air pressure outside the target room 301; if they are inconsistent, it sends a command to start the ventilation to the air pressure balancing device.
[0098] The outdoor air pressure can be a preset fixed air pressure value, or it can be the air pressure value detected by another air pressure detection device installed outside the target room 301. Optionally, the indoor air pressure and the outdoor air pressure can be determined to be consistent when they are exactly equal, or they can be determined to be consistent when the absolute value of the difference between the indoor air pressure and the outdoor air pressure is less than or equal to a preset value.
[0099] The air pressure balancing device is used to perform air exchange operation according to the start air exchange command, so as to make the indoor and outdoor air pressure of the target room 301 tend to be the same.
[0100] The pressure balancing device can be installed inside or outside the target chamber 301. The pressure balancing device can be a means of supplying gas into the target chamber 301 and / or discharging gas from the target chamber 301. For example, the pressure balancing device may include a controlled fan that adjusts the direction of gas flow based on received control signals.
[0101] Optionally, when the indoor air pressure is lower than the outdoor air pressure, a first control signal can be sent to the air pressure balancing device. The air pressure balancing device, according to the first control signal, delivers the gas outside the target room 301 into the target room 301, thereby increasing the indoor air pressure.
[0102] Control device 302 is also used to send a stop ventilation command to the air pressure balancing device in response to determining that the re-detected indoor air pressure is consistent with the outdoor air pressure.
[0103] The pressure balancing device is also used to stop the ventilation operation according to the stop ventilation command.
[0104] Specifically, during the ventilation operation performed by the air pressure balancing device, the air pressure detection device can continue to detect the air pressure in the target room 301 in real time. If the indoor air pressure obtained by the control device 302 from the air pressure detection device is consistent with the outdoor air pressure, it sends a stop ventilation command to the air pressure balancing device, and the air pressure balancing device stops performing the ventilation operation.
[0105] This embodiment, by setting up an air pressure detection device and an air pressure balancing device in the system, enables timely adjustment of the air pressure in the target room when the indoor and outdoor air pressures are inconsistent, so that the indoor and outdoor air pressures are kept consistent. This avoids the problem of the door being unable to be opened or closed due to uneven force on both sides of the door caused by the inconsistent indoor and outdoor air pressures.
[0106] Figure 5 This is a structural schematic diagram of a cold storage 500 provided in an embodiment of this application. Figure 5 As shown, the cold storage 500 specifically includes: the above-mentioned Figure 3 , Figure 4 The room gas concentration regulation system 300 and refrigeration equipment 501 described in any of the embodiments shown.
[0107] Among them, the target room included in system 500 is a refrigerated room, and the refrigeration equipment is used to regulate the temperature of the target refrigerated room.
[0108] The aforementioned refrigeration equipment 501 may include an outdoor refrigeration unit and an indoor refrigeration unit, with the indoor refrigeration unit installed inside the refrigeration room and the outdoor refrigeration unit installed outside the refrigeration room.
[0109] Normally, once the cold storage temperature reaches the set temperature, both the outdoor and indoor refrigeration units stop operating. At this time, the refrigerated compartments of the cold storage are in a closed state, and the fruits, vegetables, and other items stored there will release certain types of gases, affecting the quality of the goods. By installing the aforementioned gas concentration control system in the cold storage, the functionality of the cold storage is enhanced, and the impact of gases generated by the stored goods on their quality is reduced, extending their shelf life. Furthermore, it reduces the degree of manual intervention in monitoring the quality of stored goods, improving the efficiency of quality control.
