DETAILED DESCRIPTION
[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0050] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.
[0051] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.
[0052] At present, common cold storage only uses a constant temperature method to store products that are difficult to store, such as fruits and vegetables, flowers, and aquatic products. This will have the following problems:
[0053] 1. The environmental conditions required for the storage of fruits and vegetables, flowers and aquatic products are different. When using the constant temperature method for storage, the environmental conditions for the storage of fruits and vegetables, flowers and aquatic products cannot be met at the same time, resulting in unsatisfactory comprehensive preservation effect;
[0054] 2. When storing goods in cold storage, the parameters that affect the preservation of goods are often not just temperature. Other parameters such as light intensity, gas concentration, etc. will also affect the preservation of goods. Using a single temperature control method cannot achieve the best preservation effect.
[0055] Based on the above problems, the present invention proposes an integrated cold storage preservation control method, which includes at least one environmental control strategy. When executing any environmental control strategy, it also includes:
[0056] Detect cargo information parameters in the integrated cold storage and obtain adjustment actions matching the cargo information parameters according to the environmental control strategy;
[0057] Perform regulatory actions to adjust environmental parameters in the integrated cold storage.
[0058] The above-mentioned environmental control strategies include optimal temperature control strategy, light ratio control strategy, gas concentration control strategy, microorganism concentration control strategy, and optimal humidity control strategy. In actual application, the above-mentioned environmental control strategy can adopt one or more of the above-mentioned control strategies, so as to achieve preservation control by integrating multiple environmental conditions. At the same time, it can be seen from the above-mentioned integrated cold storage preservation control method that no matter what kind of environmental control strategy is used, it needs to be adjusted in combination with the cargo information parameters, rather than using the same control method for all cargoes. Based on this control method, the present invention can fully guarantee the preservation effect of the cargoes in the integrated cold storage.
[0059] The optimal temperature control strategy, light ratio control strategy, gas concentration control strategy, microorganism concentration control strategy, and optimal humidity control strategy in the present invention are described below, with regard to the optimal temperature control strategy:
[0060] When executing the optimal temperature control strategy, the cargo information parameters include: the initial temperature of the integrated cold storage, the empirical temperature for storing the current cargo type, the total volume of cargo in the integrated cold storage, and the total capacity of the integrated cold storage.
[0061] Based on the above cargo information parameters, when the optimal temperature control strategy is implemented in the present invention, the optimal temperature of the integrated cold storage satisfies the calculation model:
[0062]
[0063] A=V / C
[0064] Among them, T is the optimal temperature, T0 is the initial temperature of the integrated cold storage, A is the cargo filling rate in the integrated cold storage, V is the total volume of cargo in the integrated cold storage, C is the total capacity of the integrated cold storage, k is the temperature adjustment coefficient, is the time variation coefficient.
[0065] See also Figure 1 , which is a schematic diagram of the structure of the integrated cold storage proposed in the present invention, which has storage goods 6 and an ultrasonic volume measuring device 2;
[0066] When executing the above-mentioned optimal temperature control strategy, the total volume V of the stored goods 6 can be obtained by the ultrasonic volume measuring device 2. Since the total capacity C of the integrated cold storage is a known quantity, the filling rate A of the goods in the integrated cold storage can be easily calculated;
[0067] At the same time, the initial temperature T0 of the integrated cold storage and the empirical temperature T1 of the goods stored in the integrated cold storage are also known quantities. Therefore, the optimal storage temperature of the integrated cold storage can be calculated based on the above parameters to ensure the best preservation effect.
[0068] Here, the temperature adjustment coefficient k is the coefficient for adjusting the temperature according to the cargo filling rate, and the time variation coefficient As the storage time increases, the preservation temperature should be appropriately adjusted to meet the
[0069] After obtaining the optimal temperature for storage in the integrated cold storage through the above calculation model, the corresponding adjustment action can be performed to adjust the temperature in the integrated cold storage so that the temperature in the integrated cold storage reaches the above optimal temperature, thereby ensuring the preservation effect.
[0070] For the lighting ratio control strategy:
[0071] When the above-mentioned light ratio control strategy is executed, the above-mentioned cargo information parameters include: the types of cargo in the integrated cold storage, external time parameters;
[0072] The specific actions of the light ratio control strategy are as follows: when the cargo type in the integrated cold storage is plant cargo, the light ratio control strategy includes:
[0073] When the external time parameter is daytime, the proportion of red light and blue light is adjusted according to the light intensity in the integrated cold storage;
[0074] When the external time parameter is night, the ratio of red light to blue light in the integrated cold storage is set to a preset ratio.
[0075] The types of goods in the integrated goods here are mainly plant goods, such as flowers. When stored in the integrated cold storage, in order to ensure the freshness of flowers, it is necessary to promote their photosynthesis to increase the freshness of flowers;
[0076] The external time parameter is mainly used to determine whether it is day or night. For plant products, the photosynthesis effect is different during the day and at night, so the ratio of red light to blue light needs to be adjusted for day and night. At the same time, photosynthesis is also related to light intensity (since the light intensity is generally lower at night, there is no need to consider the impact of light intensity on photosynthesis at night, and there is no need to adjust the ratio of red light to blue light, just set it to the preset ratio). Therefore, during the day, different ratios of blue light to red light need to be set according to different light intensities.
[0077] Based on the above design, when executing the light ratio control strategy in the present invention, its specific work is as follows:
[0078] When the external time parameter is daytime and the light intensity in the integrated cold storage is lower than 300 lux, the ratio of red light to blue light in the integrated cold storage is set to 8:2;
[0079] When the external time parameter is daytime and the light intensity in the integrated cold storage reaches 1000 lux, the ratio of red light to blue light in the integrated cold storage is set to 1:1;
[0080] When the external time parameter is night, the ratio of red light to blue light in the integrated cold storage is set to 4:6.
[0081] See also Figure 1 The present invention is provided with an LED spectrum lamp 1 in the integrated cold storage, which can set the spectrum of the irradiated light (when the spectrum changes, the color of the irradiated light will also change accordingly, such as the red light spectrum length is 600-700nm, and the blue light spectrum length is 400-500nm) and the illumination time, so as to achieve the above-mentioned effect of adjusting the proportion of red light and blue light;
[0082] The specific lighting adjustment parameters are as follows:
[0083] Red light (600-700nm): daytime intensity 500-1000μmol / m 2 / s, night intensity 150-300μmol / m 2 / s;
[0084] Blue light (400-500nm): daytime intensity 100-200μmol / m2 / s, nighttime intensity 300-500μmol / m 2 / s.
[0085] After the above-mentioned light ratio control strategy is adopted, it can be known how to set the light ratio to ensure the best preservation effect. At this time, the above-mentioned LED spectrum lamp 1 performs corresponding adjustment actions to ensure the preservation effect.
[0086] For gas concentration control strategy:
[0087] When the above gas concentration control strategy is executed, the above cargo information parameters include: the types of cargo in the integrated cold storage;
[0088] The specific actions of its gas concentration control strategy are: when the cargo in the integrated cold storage is plant cargo, the above gas concentration control strategy includes: controlling the carbon dioxide concentration between 2%-5% and the oxygen concentration between 18%-21%;
[0089] When the cargo in the integrated cold storage is meat cargo, the above gas concentration control strategy includes: controlling the carbon dioxide concentration to be between 20% and 25% and the oxygen concentration to be between 1% and 2%.
[0090] The types of goods in the integrated cold storage here mainly refer to plant goods and meat goods. For plant goods, their respiration needs to be suppressed during preservation. Since plant goods inhale carbon dioxide and exhale oxygen during respiration, when the goods in the integrated cold storage are plant goods, the carbon dioxide concentration can be appropriately reduced to suppress their respiration, while the oxygen concentration can be increased to ensure appropriate gas exchange;
[0091] Similarly, for meat goods, in order to inhibit its respiration, it is necessary to reduce the oxygen concentration and increase the carbon dioxide concentration to reduce oxidation reactions and extend the shelf life.
[0092] In addition, for products that need to be stored in liquid, such as aquatic products, the present invention can also adjust the solubility of the gas environment to control the dissolved concentration of oxygen or carbon dioxide in water. For example, by adjusting the solubility of carbon dioxide to inhibit the oxidation process, thereby delaying corruption, when the carbon dioxide concentration reaches 25%, it automatically adjusts to reduce oxidation.
[0093] See also Figure 1 The present invention provides a gas detection and control device 7 in the integrated cold storage, which can detect the concentration of each gas and control the concentration of each gas at the same time, thereby achieving the above-mentioned control effect.
[0094] The gas concentration adjustment parameters are as follows:
[0095] Carbon dioxide concentration: plant cargo ~2%-5%, meat cargo ~20%-25%;
[0096] Oxygen concentration: plant cargo ~18%-21%, meat cargo ~1%-2%;
[0097] Nitrogen concentration: 90%-92%.
[0098] After the above-mentioned gas concentration control strategy is adopted, the respiration and oxidation can be suppressed according to the type of goods, thereby ensuring the preservation time, which is achieved through the above-mentioned gas detection and control device 7.
[0099] Strategies for controlling microbial concentration:
[0100] When the above-mentioned microbial concentration control strategy is implemented, the above-mentioned cargo information parameters include: microbial species and microbial concentration.
[0101] The specific actions of its microbial concentration control strategy are: when the type of microorganisms in the integrated cold storage is bacteria, when the bacterial concentration exceeds 10^3 CFU / m 3 When the UV light is turned on, start the UV sterilization;
[0102] When the microorganisms in the integrated cold storage are fungi, when the fungal concentration exceeds 100 CFU / m 3 When the sodium hypochlorite is released,
[0103] Here, the types of microorganisms mainly refer to bacteria and fungi, and the microbial concentrations refer to the corresponding bacterial concentrations and fungal concentrations. For bacteria, ultraviolet rays can achieve a better sterilization effect;
[0104] For fungi, sodium hypochlorite can achieve a good sterilization effect. Therefore, by detecting the above-mentioned microbial types and microbial concentrations, precise sterilization can be performed to ensure the quality of goods in the integrated cold storage.
[0105] See also Figure 1 In the present invention, a microbial detection and sterilization device 4 is provided in the integrated cold storage, wherein the sterilization device is mainly an ultraviolet lamp and a sodium hypochlorite release device. Based on the above configuration, when executing the above microbial concentration control strategy, the present invention specifically includes:
[0106] The microorganisms in the air that are likely to infringe on the goods are detected by the microorganism detection and sterilization device 4, and the specific microorganisms detected include: enterobacteriaceae, staphylococci and other microorganisms;
[0107] According to the real-time feedback from the microbial detection and sterilization device 4, the irradiation time and intensity of the ultraviolet lamp and the release amount of sodium hypochlorite are adjusted. For example, when the bacterial concentration exceeds the preset standard (10 3 CFU / m 3), the microorganism detection and sterilization device 4 will start at the set frequency, release sodium hypochlorite, and kill microorganisms in the air through ultraviolet lamps.
[0108] Through the detection of the microbial detection and sterilization device 4, the present invention can automatically start the sterilization system when the bacteria / fungus concentration exceeds the standard, ensuring that the goods in the integrated cold storage are not affected by bacteria and fungi. The microbial detection and sterilization device 4 can automatically adjust the concentration and release time of sodium hypochlorite to ensure that no side effects are produced.
[0109] The microbial concentrations and corresponding sterilization strategies are as follows:
[0110] Bacterial concentration (CFU / m 3 ): When the bacterial concentration exceeds 10^3 CFU / m 3 When the UV light is turned on, start the UV sterilization;
[0111] Fungal concentration (CFU / m 3 ): When the fungal concentration exceeds 100 CFU / m 3 When the sodium hypochlorite is released,
[0112] Through the above-mentioned microbial concentration control strategy, the present invention can detect the microbial concentration in the integrated cold storage in real time and perform corresponding sterilization actions, thereby ensuring that the goods in the integrated cold storage are not affected by bacteria and fungi and ensuring the quality of the goods.
[0113] For optimal humidity control strategy:
[0114] When executing the above optimal humidity control strategy, the above cargo information parameters include: the types of cargo in the integrated cold storage;
[0115] The specific actions of its optimal humidity control strategy are: when the cargo in the integrated cold storage is plant cargo, the humidity in the integrated cold storage is controlled between 60% and 90%;
[0116] When the goods in the integrated cold storage are aquatic products, the humidity in the integrated cold storage is controlled between 85% and 95%.
[0117] The types of goods in the integrated cold storage here are mainly plant goods and aquatic products. For plant goods, such as fruits, vegetables, flowers, etc., it can increase the humidity in the air to preserve moisture to increase the preservation time. The specific solution can be ultrasonic humidification;
[0118] For aquatic products, the shelf life can be increased by humidifying the water source. The specific solution is to use the spray humidification method.
[0119] See also Figure 1The present invention is provided with a humidity detection and humidification device 5 in the integrated cold storage, and the humidity detection and humidification device 5 can perform the above-mentioned ultrasonic humidification and spray humidification methods. Based on the above-mentioned settings, the present invention specifically includes:
[0120] For plant cargo, when the humidity in the integrated cold storage is lower than 60%, the ultrasonic humidifier is controlled to turn on and adjust the humidity to between 60% and 90%;
[0121] When the humidity in the integrated cold storage is higher than 90%, turn on the dehumidification equipment and control the humidity between 60% and 90% through air circulation and temperature control system;
[0122] For aquatic products, when the humidity in the integrated cold storage is lower than 85%, the spray system is started to control the humidity between 85% and 95%.
[0123] After the optimal humidity control strategy is adopted, the humidity in the integrated cold storage can be maintained at the optimal humidity, thereby fully ensuring the activity of the goods in the integrated cold storage.
[0124] See also Figure 1 In the present invention, a biometric information barcode scanning device 3 is also provided in the integrated cold storage, and the biometric information barcode scanning device 3 is used to scan to obtain the types of goods in the integrated cold storage, such as plant goods, meat goods, aquatic products, etc. mentioned above, so as to obtain the goods information parameters in the environmental control strategy and perform corresponding adjustment actions.

[0130] A humidity detection and humidification device 5, which is mainly used to implement the optimal humidity control strategy as described above;
[0131] A gas detection and control device 6, which is mainly used to implement the gas concentration control strategy as described above;
[0132] Based on the above Figure 2 The overall process of the integrated cold storage control method proposed in the present invention is:
[0133] First, the "goods biological information" is obtained through the biological information barcode scanning device 3, that is, the types of goods in the integrated cold storage;
[0134] Then the “cargo volume”, i.e. the total volume of the cargo in the integrated cold storage mentioned above, is obtained by using the ultrasonic volume measuring device 2;
[0135] Then the obtained "goods biological information", "goods volume" and "planned storage time" are input into the central control system as goods information parameters;
[0136] The central control system is respectively connected to the compressor (which is used to implement the optimal temperature control strategy), the microbial detection and sterilization device 4 (which is used to implement the microbial concentration control strategy), the humidity detection and humidification device 5 (which is used to implement the optimal humidity control strategy), the gas detection and control device 7 (which is used to implement the gas concentration control strategy), and the LED spectrum lamp 1 (which is used to implement the light ratio control strategy). After the central control system obtains the above-mentioned "cargo biological information", "cargo volume" and "planned storage time", it can execute the corresponding control strategy according to the above-mentioned cargo information parameters, and finally adjust the environment in the integrated cold storage to the optimal fresh-keeping storage environment.
[0137] Based on the above scheme, the present invention also proposes an integrated cold storage, which includes: a detection unit, a main control unit, and an execution unit;
[0138] The detection unit is used to detect cargo information parameters in the integrated cold storage;
[0139] The main control unit stores at least one environmental control strategy, and can obtain an adjustment action that matches the cargo information parameters when executing any environmental control strategy;
[0140] The execution unit is used to execute the adjustment action.
[0141] The detection unit here may be an ultrasonic volume measurement device 2 and a bio-information barcode scanning device 3;
