[0029] The embodiments of the present application provide a food storage temperature automatic control device, as shown in Figure 1 The device comprises:

[0030] The VOC sensor network setting module 10 is used to set a VOC sensor network, which is arranged in a storage space of a food storage device. Specifically, the specific needs of the food storage device are analyzed, including the type of stored food, the expected VOC emission characteristics, the size and shape of the storage space, etc. According to the results of the demand analysis, the coverage, number, type and accuracy requirements of the VOC sensor network are determined. Among them, VOC (Volatile Organic Compounds) refers to organic compounds that are easy to volatilize at room temperature. During the food storage process, the food itself or its packaging materials will release VOC, affecting the quality of the food and the storage environment. The VOC sensor network refers to a network composed of multiple VOC sensors, which is used to monitor the VOC concentration and distribution in the food storage device in real time. According to the internal structure of the food storage device, the layout of the VOC sensor network is designed to evenly distribute the sensors in the storage space to monitor the VOC distribution comprehensively. The selected VOC sensors are installed in the storage space of the food storage device according to the network layout design requirements, and the VOC sensor network is integrated with the control system, so that the sensors can transmit the detected VOC data to the control system for processing and analysis in real time.

[0031] The volatile organic compound detection module 20 is used to detect volatile organic compounds in the food in the storage space according to the VOC sensor network, and outputs a VOC sensor data set. Specifically, when the food storage device starts to work, or reaches a preset detection time interval, the volatile organic compound detection module 20 starts, sends a start signal to the VOC sensor network, and activates each sensor to start detection. Each sensor in the VOC sensor network starts to work, detects the concentration of volatile organic compounds in the storage space, and converts the detected VOC concentration data into an electrical signal. Through a preset data transmission protocol, these data are transmitted to the volatile organic compound detection module 20. The volatile organic compound detection module 20 pre-processes the received data, including data verification, denoising, filtering, etc., to ensure the accuracy and reliability of the data. The processed data is integrated into a VOC sensor data set according to the preset format and rules. The VOC sensor data set contains VOC concentration information at different positions and different time points in the storage space, which is used to analyze the distribution and trend of VOC.

[0032] The space purification device setting module 30 is used to set a space purification device, which is arranged inside the food storage device. The space purification device includes a purification port arranged on the inner wall of the storage space, and the purification port purifies the storage space through a purification pipeline. Specifically, the spatial structure of the food storage device, the purification requirements (such as purification speed, purification efficiency, etc.) and the characteristics of the generated volatile organic compounds are analyzed, and the type, specification and purification capacity of the space purification device are determined according to the analysis results. The space purification device is a device or system for removing contaminants in the food storage space. Clean air or purifying agent is introduced into the storage space through the purification port and the purification pipeline to remove VOC and other pollutants. The number and position of the purification ports are designed to cover the key areas in the storage space to maximize the purification effect. The purification port is an opening arranged on the inner wall of the storage space for introducing purified air or purifying agent into the storage space. The layout of the purification pipeline is designed to uniformly distribute the purification airflow to the entire storage space. The purification pipeline is a pipeline system connecting the purification port and the purification equipment for transporting purified air or purifying agent. According to the purification requirements and the characteristics of VOC, the purification technology (such as adsorption, catalytic oxidation, activated carbon filtration, etc.) is determined. Inside the food storage device, the purification port and the purification pipeline are installed according to the design scheme, and the purifier is connected with the purification pipeline to ensure that the purification pipeline is unobstructed.

[0033] The purification control parameter output module 40 is used to input the VOC sensing data set into the purification control module of the space purification device and output the purification control parameters that meet the preset purification effect. Specifically, the VOC sensing data set includes real-time VOC concentration value, VOC species, concentration change trend and other information. The purification control module of the space purification device preprocesses the received VOC sensing data set, such as data cleaning, outlier processing, data conversion, etc. The processed data is analyzed to evaluate whether the current VOC concentration exceeds the preset safety threshold and the trend of VOC concentration change. According to the VOC concentration and the change trend, the purification requirement of the current space purification device is evaluated, and based on the purification requirement and the state of the current space purification device (such as fan speed, purifier working mode, etc.), the purification control parameters that meet the preset purification effect are calculated, that is, the parameters for controlling the working state of the space purification device, including fan speed, purifier working mode, purifying agent dosage, etc. The preset purification effect is the expected purification effect set by the user or the system, such as reducing the VOC concentration to below a certain safety threshold, maintaining good air quality in the storage space, etc.

[0034] In a possible implementation, the VOC sensing data set is input into a purification control module of the space purification device, and a purification control parameter meeting a preset purification effect is output, including: obtaining a VOC sensing data set, the VOC sensing data set including a volatile organic compound concentration, a pollutant type, and a pollution change rate. Specifically, the volatile organic compound concentration refers to the content or concentration level of the volatile organic compound in the storage space, the pollutant type refers to different types of volatile organic compound pollutants existing in the storage space, and the pollution change rate refers to the change amount of the volatile organic compound concentration in the storage space per unit time. The VOC sensing data set is input into the purification control module of the space purification device for parameter analysis, and the purification control parameter is obtained with the preset purification effect as the target; wherein the purification control parameter includes an air circulation speed, a purification agent delivery adjustment, and a purification operation time. Specifically, the VOC sensing data set is transmitted to the purification control module of the space purification device in a wired or wireless manner, and the purification control module checks the data after receiving the data to ensure the accuracy and integrity of the data. According to a preset purification effect (such as reducing the volatile organic compound concentration to below a certain threshold value), the required purification intensity is analyzed in combination with the current volatile organic compound concentration, the pollutant type, and the pollution change rate, and the required purification control parameter is calculated according to the purification demand analysis result, including the air circulation speed, the purification agent delivery adjustment, and the purification operation time. This implementation can more accurately judge the pollution condition of the current storage space by monitoring the volatile organic compound concentration, the pollutant type, and the pollution change rate in real time, so as to output more suitable purification control parameters, thereby achieving the technical effect of improving the accuracy of the purification control parameter.

[0035] The temperature influence analysis module 50 is used to connect the space purification device with a first temperature control module, input the purification control parameter into the first temperature control module for temperature influence analysis, and obtain a first temperature control parameter. Specifically, the space purification device and the first temperature control module are connected, the first temperature control module receives the purification control parameter, and the purification control parameter is calculated based on the VOC sensing data set and is used to guide the working state of the space purification device. The first temperature control module performs format conversion and data processing (parameter calibration, unit conversion, etc.) on the received purification control parameter, combines the control logic of the first temperature control module, performs temperature influence analysis, including simulating the working effect of the space purification device under different temperature conditions, evaluating the influence of temperature on the purification effect, etc. Based on the result of the temperature influence analysis, the first temperature control module calculates the first temperature control parameter, and the first temperature control parameter is used to control the temperature of the space purification device to ensure that the purification effect is optimal under suitable temperature conditions.

[0036] In a possible implementation, the purification control parameters are input into the first temperature control module for temperature influence analysis to obtain first temperature control parameters, including initializing temperature control parameters, the temperature control parameters including a target temperature point and a temperature variation range. Specifically, the target temperature point required in the purification process is determined based on purification efficiency, chemical reaction rate or other related factors, and a temperature variation range is set in combination with the safety and stability of the equipment, including the upper and lower limits of the target temperature point. The initialized temperature control parameters are used in the first temperature control module, and temperature influence feedback control is performed based on a PID controller to output the first temperature control parameters. Specifically, the initialized temperature control parameters (the target temperature point and the temperature variation range) are input into the first temperature control module. The first temperature control module monitors the current temperature in real time and feeds back the temperature data to the PID controller (a control algorithm that calculates the error between the expected output and the actual output and adjusts the control parameters according to the error to achieve accurate control of the system), and the PID controller calculates the control output (for example, heating or cooling power) according to the target temperature point, the current temperature and the temperature variation range. The first temperature control module adjusts the working state of the heating or cooling equipment according to the output of the PID controller to change the temperature of the storage space. After a period of adjustment and control, the first temperature control module gradually approaches and stabilizes at the target temperature point, at this time, the first temperature control module outputs the final first temperature control parameters according to the current operating state and the output of the PID controller, including the stable heating / cooling power, the temperature fluctuation range, etc. This implementation realizes accurate temperature control through the feedback control mechanism of the PID controller, and achieves the technical effect of ensuring that the purification process is carried out under optimal conditions and improving the purification efficiency.

[0037] The purification temperature control module 60 is used for purifying temperature control of the space purification device with the first temperature control parameter. Specifically, the purification temperature control module 60 receives the first temperature control parameter output from the temperature influence analysis module 50, formulates a specific temperature control strategy according to the first temperature control parameter, including different operations such as heating, refrigeration, constant temperature, and corresponding operation sequence, time interval, temperature threshold, etc. The purification temperature control module 60 interfaces with the temperature control system of the space purification device, sends temperature control instructions to the temperature control system through standard communication protocols and data transmission formats, including starting heating, starting refrigeration, adjusting temperature setting value, etc. In the temperature control process, the purification temperature control module 60 continuously monitors the state of the temperature control system, and if it finds that the actual temperature deviates from the target temperature or the temperature control system appears abnormal, it adjusts the temperature control strategy or takes other measures in time. The embodiments of the present application use the technical means of real-time monitoring of volatile organic compound concentration in food storage space through VOC sensing network, setting space purification device, purification control analysis through purification control module, temperature influence analysis, etc. The technical effects of comprehensive temperature control and volatile organic compound removal, reducing pollution and damage to food, and improving the effect and safety of food storage are achieved.

[0038] As Figure 2In a possible implementation, as shown, purifying the space purifying device according to the first temperature control parameter includes obtaining a purifying mode, purifying material, and purifying path of the space purifying device. Specifically, detailed information about the purifying mode (techniques or methods for removing pollutants in the air, such as chemical adsorption, photocatalysis, electrostatic dust removal, etc.), purifying material (medium or substance used in the purifying process, used for adsorbing, decomposing, or converting pollutants, such as activated carbon, photocatalyst, etc.), and purifying path (such as air flow direction, processing steps, etc.) of the space purifying device is collected. According to the correlation degree of the purifying mode, purifying material, and purifying path with temperature influence, mode-temperature sensitivity, material-temperature sensitivity, and path-temperature sensitivity are output. Specifically, based on scientific research and experimental data, the sensitivity of each purifying mode, purifying material, and purifying path to temperature is evaluated, and the evaluation result is quantified as mode-temperature sensitivity, material-temperature sensitivity, and path-temperature sensitivity indexes, where the temperature sensitivity refers to the sensitivity of the purifying mode, purifying material, or purifying path to temperature change, that is, the influence degree of temperature change on the purifying effect. According to the mode-temperature sensitivity, the material-temperature sensitivity, and the path-temperature sensitivity, a fitted temperature sensitivity is obtained. Specifically, according to the importance or contribution of each purifying mode, purifying material, and purifying path in the overall purifying process, a weight is assigned to the corresponding temperature sensitivity, and the weighted mode-temperature sensitivity, material-temperature sensitivity, and path-temperature sensitivity are summed to obtain the fitted temperature sensitivity, which is a comprehensive index for evaluating the sensitivity of the entire space purifying device to temperature. If the fitted temperature sensitivity is greater than a preset sensitivity, the first temperature control module is activated. Specifically, the calculated fitted temperature sensitivity is compared with the preset sensitivity threshold, and if the fitted temperature sensitivity is greater than the preset sensitivity, it indicates that the current space purifying device is sensitive to temperature change and needs to be temperature-controlled. At this time, the first temperature control module is activated, and the space purifying device is temperature-adjusted according to the first temperature control parameter. This implementation evaluates the sensitivity of the space purifying device to temperature and controls the temperature accordingly, ensuring that the space purifying device operates within a suitable temperature range and achieving the technical effect of avoiding negative effects of excessively high or low temperature on the purifying effect.

[0039] In a possible implementation, when the path-temperature sensitivity is greater than the preset sensitivity, a heat dissipation mechanism is configured in the purification pipeline of the space purification device; the heat dissipation mechanism is composed of a heat dissipation material, and the heat dissipation mechanism is used to dissipate heat from the purification pipeline. Specifically, the path-temperature sensitivity reflects the influence degree of the temperature change in the purification pipeline on the purification efficiency, and according to the equipment design requirements, material performance, user demand and other factors, a preset sensitivity threshold is set, the calculated path-temperature sensitivity is compared with the preset sensitivity threshold, if the path-temperature sensitivity is greater than the preset sensitivity threshold, a heat dissipation mechanism is configured in the purification pipeline of the space purification device, the heat dissipation mechanism is a device for reducing the temperature of the purification pipeline, and the heat dissipation mechanism is composed of a heat dissipation material. The heat dissipation mechanism can include heat dissipation fins, heat dissipation fans, heat pipes and other components. When the temperature in the purification pipeline rises, heat is transferred to the heat dissipation mechanism through the pipeline wall, and the heat dissipation mechanism dissipates the received heat to the surrounding environment through natural convection of the heat dissipation fins, forced convection of the heat dissipation fans or heat conduction of the heat pipes, so as to reduce the temperature of the pipeline. This implementation effectively reduces the temperature of the pipeline by configuring the heat dissipation mechanism when the path-temperature sensitivity is high, and achieves the technical effect of improving the purification efficiency.

[0040] In one possible implementation, a temperature sensing network is provided to perform real-time temperature detection on the storage space and obtain a temperature sensing data set. Specifically, the temperature sensing network is a network composed of multiple temperature sensors for real-time monitoring of temperature distribution and changes in the storage space. According to the size, shape and distribution characteristics of the food in the storage space, the positions where the temperature sensors need to be arranged are determined to ensure the comprehensiveness and accuracy of temperature detection in the storage space. According to actual needs, the temperature sensors are selected, and the selected temperature sensors are arranged and installed at predetermined positions to ensure good thermal contact between the temperature sensors and the storage space and accurate temperature sensing. The temperature sensors are network-connected to the control system to enable real-time data transmission to the control system for processing. The temperature sensing network collects temperature data in the storage space in real time and sends the data to the control system, which processes the received temperature data to generate a temperature sensing data set including temperature changes at different times and different positions. The storage requirement temperature of the food is obtained. Specifically, according to the type of stored food, the storage requirement temperature range or the optimal storage temperature is queried, and the queried storage requirement temperature is set as the target temperature value in the control system. A second temperature control module is provided, which controls and analyzes the temperature sensing data set with the storage requirement temperature as the target to obtain a second temperature control parameter. Specifically, a temperature control algorithm such as a PID control algorithm is configured in the control system, the initial parameters of the control algorithm are set according to the storage requirement temperature of the food and the actual temperature of the storage space, the second temperature control module is started, the temperature sensing data set from the temperature sensing network is received, the temperature sensing data set is analyzed and processed by using the configured control algorithm, the deviation between the current temperature and the target temperature is determined, and the temperature adjustment amount required is calculated, the second temperature control parameter is generated based on the analysis and processing result. The storage space of the food storage device is controlled according to the second temperature control parameter. Specifically, the generated second temperature control parameter is converted into a control signal and sent to a temperature adjusting device (such as a refrigerator, a heater, a fan, etc.), and the temperature adjusting device performs corresponding actions such as refrigeration, heating, ventilation, etc. according to the signal content to control the temperature of the storage space. The control system continuously monitors the temperature changes in the storage space and adjusts the temperature control parameter according to the feedback result to ensure that the temperature of the storage space always remains within the set target temperature range. This implementation controls the temperature of the storage space to ensure that the temperature of the storage space always remains within the set target temperature range, thereby achieving the technical effect of ensuring the quality and safety of the food.

[0041] In a possible implementation, the first temperature control module and the second temperature control module independently perform temperature control. Specifically, the first temperature control module is a module for purifying temperature control of the space purification device, ensuring that the space purification device operates at an appropriate temperature to improve purification efficiency; the second temperature control module is a module for temperature control of the storage space of the food storage device, ensuring that the food is stored at an appropriate temperature to maintain its freshness and quality. In this implementation, the first temperature control module and the second temperature control module independently perform temperature control, i.e., they are optimized and adjusted according to their respective requirements without affecting each other, achieving the technical effects of improving the flexibility and accuracy of control.

[0042] In a possible implementation, the second temperature control module and the first temperature control module are integrated to output a temperature integrated control module. Specifically, the functions of the first temperature control module and the second temperature control module are integrated, and a unified temperature integrated control module is designed. The temperature integrated control module is a control module that integrates the functions of the first temperature control module and the second temperature control module, and is used to uniformly manage and optimize the temperature control parameters of the two temperature control modules. According to the temperature integrated control module, the first temperature control parameter and the second temperature control parameter are neutralized and analyzed to obtain integrated temperature control parameters. Specifically, the temperature integrated control module receives temperature control parameters from the first temperature control module and the second temperature control module, performs neutralization and analysis, analyzes the existing temperature control conflicts, such as a large difference between the target temperatures of the two temperature control modules, and adjusts and optimizes the integrated temperature control parameters according to the analysis results to balance the temperature control requirements of the two temperature control modules. According to the results of neutralization and analysis, the integrated temperature control parameters are generated, including a unified target temperature, an adjusted temperature fluctuation range, and an optimized heating / cooling power. The first temperature control module and the second temperature control module are controlled according to the integrated temperature control parameters. Specifically, the generated integrated temperature control parameters are sent to the first temperature control module and the second temperature control module, and the two temperature control modules perform temperature control operations according to the received integrated temperature control parameters. This implementation uniformly manages and optimizes the temperature control parameters of the two temperature control modules through the temperature integrated control module, reducing unnecessary energy waste and achieving the technical effect of saving energy.
