[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0046] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0047] In one embodiment, a cold storage is provided, referring to Figure 1 The cold storage comprises a storage room 1, a cache room 2 and a cold storage control device. A switch door 4 is provided between the storage room 1 and the cache room 2. A cold storage door 5 is provided on the opposite side of the cache room 2 opposite to the lifting door. A detection device is provided in each of the storage room 1 and the cache room 2. The detection device is used to collect cold storage detection parameters and upload them to the cold storage control device. The cold storage detection parameters include the switch state of the cold storage door 5 and the environment parameters in the cold storage.

[0048] The cold storage control device is used to control the cold storage to operate in the first door closing mode when the cold storage door 5 is in the open state, wherein the switch door 4 between the storage room 1 and the cache room 2 in the cold storage is in the closed state in the first door closing mode; or, when the cold storage door 5 is in the closed state, the working mode of the cold storage is controlled according to the environmental parameters in the storage, and the switch state of the switch door 4 is different in different working modes of the cold storage.

[0049] Specifically, Figure 1 As shown, the cold storage has two doors. The switch door 4 is arranged between the storage room 1 and the cache room 2, and is used to control the air circulation state between the storage room 1 and the cache room 2. The switch door 4 can be a lifting door or a sliding door. The cold storage door 5 is arranged on the opposite side of the cache room 2 relative to the switch door 4, and is used to control the air circulation state between the cache room 2 and the outside air. The cold storage door 5 can be any one of a lifting door, a swing door or a sliding door. The detection device at least includes an air temperature sensor, a humidity sensor, a gas detection sensor 3, a switch detection device, etc. The gas detection sensor 3 is used to detect the gas detection concentration of the preset gas in the storage room 1 and the cache room 2, and the switch detection device is used to detect the switch state of the cold storage door 5. That is, the cold storage detection parameters include the switch state of the cold storage door 5 and the environmental parameters in the warehouse. The environmental parameters in the warehouse at least include temperature, humidity, gas detection concentration, etc.

[0050] The cold storage control device determines the switch state of the cold storage door 5 according to the received cold storage detection parameters, and controls the switch door 4 to close when the cold storage door 5 is open, so as to prevent the outside air from flowing into the storage room 1 through the buffer room 2, thereby affecting the storage environment of the goods stored in the storage room 1 and affecting the quality of the stored goods, so as to solve the problem that the existing cold storage door is frequently opened to introduce outside air and affect the quality of the stored goods. The cold storage control device can also control the switch state of the switch door 4 according to the cold storage detection parameters when the cold storage door 5 is closed, so as to dynamically adjust the storage environment of the buffer room 2 and the storage room 1.

[0051] In one embodiment, the detection device further includes an article temperature sensor, and the article temperature sensor is used to collect the detection temperature of the goods stored in the cache room 2 and upload it to the cold storage control device.

[0052] Specifically, the item temperature sensor is used to collect the detected temperature of the goods stored in the cache room 2. The cold storage control device can determine whether the goods stored in the cache room 2 have been pre-cooled based on the detected temperature. The pre-cooled stored goods can be transferred to the storage room 1 for storage.

[0053] In one embodiment, a conveying device is provided in the cache room 2 through the bottom of the switch door 4 toward the storage room 1, and the cold storage control device is also used to control the working state of the conveying device.

[0054] Specifically, the conveying device includes a conveyor belt 6 and a conveying motor. The conveyor belt 6 is laid at the bottom of the switch door 4 along the direction in which the external air flows into the storage room 1. When the conveyor belt 6 moves in a first direction, the stored goods in the buffer room 2 can be conveyed to the storage room 1 to achieve the goods entering the warehouse. When the conveyor belt 6 moves in a second direction, the stored goods in the storage room 1 can be conveyed to the buffer room 2 to achieve the goods leaving the warehouse. The working states of the conveying device are divided into a shutdown state, a start-entry state, and a start-exit state to meet different transportation requirements for goods.

[0055] In one embodiment, Figure 3 is a flow chart of a cold storage control method in one embodiment, referring to Figure 3 , a cold storage control method is provided. This embodiment mainly uses the method applied to a cold storage control device as an example, and the cold storage control method specifically includes the following steps:

[0056] Step S210, obtaining cold storage detection parameters, wherein the cold storage detection parameters include the opening state of the cold storage door 5 of the cold storage and the internal environment parameters of the cold storage.

[0057] Specifically, the cold storage detection parameters are collected by the detection device in the cold storage and uploaded to the cold storage control device. The opening state of the cold storage door 5 is used to indicate whether there is external air entering the cold storage. If the opening state of the cold storage door 5 is open, it means that the external air is entering the cold storage at this time; on the contrary, if the opening state of the cold storage door 5 is closed, it means that the external air has not entered the cold storage at this time and will not affect the stored goods in the cold storage. The internal environmental parameters at least include the internal temperature, the internal humidity, the gas detection concentration of the preset gas in the cold storage, etc. The preset gas includes carbon dioxide, oxygen, nitrogen, etc.

[0058] Step S220, when the opening state of the cold storage door 5 is open, control the cold storage to operate in a first door closing mode, wherein in the first door closing mode, the switch door 4 between the storage room 1 and the cache room 2 in the cold storage is in a closed state; or,

[0059] Step S230, when the open state of the cold storage door 5 is closed, the working mode of the cold storage is controlled according to the environmental parameters in the cold storage, and the opening and closing states of the opening and closing door 4 are different when the cold storage is in different working modes.

[0060] Specifically, when the cold storage door 5 is in different switch states, it needs to operate in different working modes to avoid affecting the stored goods in the cold storage. When the cold storage door 5 is open, external air enters the cold storage. In order to prevent the external air from affecting the stored goods in the storage room 1, the switch door 4 between the storage room 1 and the cache room 2 is closed, that is, the cold storage is controlled to work in the first door closing mode. Later, if the outbound instruction is received, the switch door 4 is controlled to open to process the goods outbound. However, when it is confirmed that it is a warehousing scenario, the goods are preferentially stored in the cache room 2 for preliminary caching and pre-cooling, so as to ensure that the storage environment in the storage room 1 will not be affected by external air, and prevent external air from entering the storage room 1 to affect the storage environment in the storage room 1, thereby affecting the quality of the stored goods, so as to solve the problem that the existing cold storage door is frequently opened to introduce external air and affect the quality of stored items.

[0061] When the cold storage door 5 is closed, the opening and closing state of the door 4 is determined in combination with the environmental parameters in the storage to dynamically adjust the storage environment of the cache room 2 and the storage room 1 so that the storage environment of the storage room 1 and the cache room 2 can extend the preservation time of the stored goods.

[0062] In one embodiment, referring to Figure 4 and Fig. 9 , controlling the working mode of the cold storage according to the environmental parameters in the cold storage, including:

[0063] Step S2301, when the first gas concentration of the preset gas in the storage room 1 is greater than or equal to the preset concentration, the cold storage is controlled to operate in the second mode, wherein in the second mode the storage room 1 is in a fresh air ventilation state, and the internal environmental parameters include the first gas concentration.

[0064] Specifically, the first gas concentration indicates the carbon dioxide concentration in the storage room 1, which is recorded as A 1 , the preset concentration is recorded as A 0, a reference standard for indicating excessive carbon dioxide concentration. When the preset concentration is high, the ventilation frequency will be low, resulting in a high gas concentration in storage room 1 and cache room 2, which will shorten the shelf life of the goods. However, when the preset concentration is low, the ventilation frequency will be high, resulting in higher energy consumption for cold storage operation. Therefore, the preset concentration needs to be customized and balanced based on the actual shelf life of the goods and the actual energy consumption for cold storage operation in actual applications.

[0065] In A 1 ≥A 0 When , it means that the carbon dioxide concentration in storage room 1 is high. When the goods stored in storage room 1 are fruits and vegetables, they will undergo anaerobic respiration and affect the quality of the goods. In this case, it is necessary to reduce the carbon dioxide concentration in storage room 1 and turn on the fresh air ventilation state for storage room 1. The carbon dioxide concentration in storage room 1 can be reduced by fresh air ventilation to optimize the storage environment in storage room 1.

[0066] In one embodiment, Figure 5 and Fig. 9 , controlling the working mode of the cold storage according to the environmental parameters in the cold storage, including:

[0067] Step S2302, when the second gas concentration of the preset gas in the cache room 2 is greater than or equal to the preset concentration, the cold storage is controlled to operate in a third mode, wherein in the third mode, the switch door 4 is in an open state, and the storage room 1 is in a fresh air ventilation state, and the environmental parameters in the storage include the second gas concentration.

[0068] Specifically, the second gas concentration indicates the carbon dioxide concentration in the buffer room 2, which is recorded as A 2 , in A 2 ≥A 0 , it means that the carbon dioxide concentration in the cache room 2 is high, but because the cold storage door 5 is in a closed state, it is necessary to open the switch door 4 and start the fresh air ventilation mode of the storage room 1 to put the storage room 1 in a fresh air ventilation state, so that the storage room 1 and the cache room 2 are connected and ventilated, so as to ventilate the cache room 2 and reduce the carbon dioxide concentration in the cache room 2.

[0069] In one embodiment, Figure 6 and Fig. 9 , controlling the working mode of the cold storage according to the environmental parameters in the cold storage, including:

[0070] Step S2303, when the first gas concentration of the preset gas in the storage room and the second gas concentration of the preset gas in the cache room are both less than the preset concentrations, the cold storage is controlled to operate in a fourth mode, wherein in the fourth mode the switch door 4 is in a closed state, and the storage room 1 is in a non-fresh air ventilation state.

[0071] Specifically, when the first gas concentration and the second gas concentration are both lower than the preset concentration, it indicates that the carbon dioxide concentration in the storage room 1 and the cache room 2 is low. There is no need to turn on the fresh air ventilation for the storage room 1, nor is there a need to connect the storage room 1 and the cache room 2 to ventilate the cache room 2. Therefore, the switch door 4 is controlled to be closed, and the storage room 1 turns off the fresh air ventilation mode, which can reduce the operating energy consumption of the cold storage.

[0072] In one embodiment, Figure 7 and Fig. 9 , when the first gas concentration of the preset gas in the storage room and the second gas concentration of the preset gas in the cache room are both less than the preset concentration, after controlling the cold storage to operate in the fourth mode, the method further includes:

[0073] Step S2304, when the working time of the fourth mode reaches a first preset time, obtaining a first concentration growth rate of the storage room 1 within the preset time, and a second concentration growth rate of the cache room 2 within the preset time;

[0074] Step S2305, when the second concentration growth rate is greater than the first concentration growth rate, controlling the cold storage to operate in a fifth mode, wherein the switch door 4 is in an open state in the fifth mode.

[0075] Specifically, when the working time of the fourth mode reaches the first preset time, the first concentration growth rate and the second concentration growth rate are obtained, including: re-obtaining the carbon dioxide concentration in the storage room 1 to obtain the third gas concentration, and re-obtaining the carbon dioxide concentration in the cache room 2 to obtain the fourth gas concentration, and determining the first concentration growth rate based on the difference between the third gas concentration and the first gas concentration, that is, ΔA 1 =A 1 '-A 1 , the second concentration growth rate is determined based on the difference between the fourth gas concentration and the second gas concentration, that is, ΔA 2 =A 2 '-A 2 .

[0076] When ΔA 2 >ΔA 1When the temperature of the cold storage room 1 is low, the door 4 between the buffer room 2 and the storage room 1 is opened, the buffer room 2 and the storage room 1 are connected, and the cold air in the storage room 1 enters the buffer room 2 to pre-cool the stored goods in the buffer room 2, so that the carbon dioxide release rate of the fruit and vegetable stored in the buffer room 2 is reduced. The second concentration growth rate is detected in a subsequent cycle. When the second concentration growth rate is less than the first concentration growth rate, the door 4 is closed, and the working mode of the cold storage is restored to the fourth mode, so as to avoid long-term opening of the door 4, which may cause large temperature fluctuations in the storage room 1 and affect the stored goods in the storage room 1.

[0077] In one embodiment, Figure 8 and Fig. 9 , controlling the working mode of the cold storage according to the environmental parameters in the cold storage, including:

[0078] Step S2306, when the temperature change rate of the goods stored in the cache room 2 within the second preset time period is less than the preset change rate, the cold storage is controlled to operate in the sixth mode, wherein the storage environment parameters include the temperature change rate of the goods stored in the cache room 2 within the second preset time period, and in the sixth mode, the switch door 4 is in an open state, and the conveying device laid from the cache room 2 to the storage room 1 through the bottom of the switch door 4 is in a started warehousing state, which is used to transfer the stored goods located on the top of the conveyor belt 6 from the cache room 2 to the storage room 1, and the conveying device includes the conveyor belt and a drive motor.

[0079] Specifically, the temperature change rate within the second preset time period is used to indicate the temperature fluctuation of the stored goods. If the temperature change rate is less than the preset change rate, it means that the temperature of the goods stored in the cache room 2 gradually cools down and then tends to stabilize. At this time, it is determined that the pre-cooling of the stored goods in the cache room 2 is completed, and the stored goods in the cache room 2 can be transferred to the storage room 1. By starting the conveying device, the stored goods located in the cache room 2 and on the conveyor belt 6 are conveyed to the storage room 1 through the opening and closing door 4. In this way, the stored goods are automatically transferred to the storage room 1 after the pre-cooling of the cache room 2 is completed, thereby saving the labor cost of manually transferring the pre-cooled stored goods, improving the transfer efficiency, reducing the probability of external air entering the cold storage, and extending the preservation time of the cold storage for the stored goods.

[0080] Figures 3 to 9 FIG. 1 is a flow chart of a cold storage control method in one embodiment. It should be understood that although Figures 3 to 9 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figures 3 to 9At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0081] In one embodiment, Fig.10 As shown, a cold storage control device is provided, comprising:
