[0049] This invention realizes dynamic optimization management of cabinet environment through multimodal sensor fusion and intelligent decision-making algorithm. The specific working principle is as follows:
[0050] 1. Data Collection and Fusion
[0051] Image acquisition module: Dual-mode infrared / visible light cameras deployed on the cabinet roof and door panels capture panoramic images of the cabinet interior every 10 minutes. Infrared imaging identifies areas of abnormal temperature (such as localized heat release from spoiled food), while visible light images use multispectral analysis (wavelength 400-1000nm) to detect organic residue (such as oil stains and mold). Furthermore, micro-weighing sensors built into the door panels monitor the weight changes of items on the shelves in real time and, combined with image recognition results, determine the storage status of the items.
[0052] Environmental monitoring module: The temperature and humidity sensors collect data every 30 seconds, and the VOC sensor detects the concentration of volatile organic compounds such as formaldehyde and ethanol. The data is transmitted to the intelligent control unit via the SPI bus.
[0053] Odor analysis module: The metal oxide semiconductor (MOS) sensor array operates in differential detection mode, quantifying NH3 / H2S concentration through conductivity changes and eliminating interference from ambient temperature drift.
[0054] 2. Intelligent Analysis and Decision-making
[0055] Cleanliness score calculation: The CNN model is fine-tuned and trained based on the ResNet-18 architecture, with pre-processed image data (normalized to 224×224 and enhanced in HSV color space) as input. The model outputs the confidence score C for contaminants such as oil stains and mold. i , weight w i Dynamic allocation according to the pollutant hazard level (such as mold w1 = 0.4, oil stain w2 = 0.3). C When <0.6, it is determined that the cleaning status inside the cabinet does not meet the standard.
[0056] Corruption risk index generation: weight coefficient α = 0.5 (temperature dominated), β = 0.3, γ = 0.2, when R d When the value is >0.8, it indicates a high risk of corruption. The system also analyzes VOC concentration spike patterns (e.g., ethanol concentration increases by 50 ppm within 2 hours) to assist in confirming corruption events.
[0057] Dynamic response strategy: When the first level response is activated, the dehumidification power is Dynamic adjustment; after the second-level response is triggered, the UV-C lamp works in pulse mode (5s on / 2s off) to reduce ozone generation; the third-level response calls the third-party service provider interface through the cloud API, and attaches a snapshot of environmental data when pushing the service.
[0058] 3. Closed-loop optimization mechanism
[0059] The self-learning algorithm is based on historical S C Data, using the exponential weighted moving average method to update the cleaning cycle T clean If S for 3 consecutive days C >0.8, the cleaning interval will be automatically extended to 1.2T basc , reducing energy consumption.
[0060] The pre-dehumidification mode uses an LSTM neural network to predict humidity changes in the next 6 hours. If the predicted H>65% and the confidence level>90%, the dehumidification device is started 30 minutes in advance to a standby power of 100W.
[0061] The present invention provides an intelligent stainless steel cabinet. It has the following beneficial effects:
[0062] 1. The present invention realizes cleanliness score S by using multispectral imaging and sensor fusion technology. c Corruption Index R d The quantitative assessment improves detection accuracy by more than 40% compared with traditional solutions. In addition, the real-time push of environmental reports and maintenance suggestions via the APP increases user operation efficiency by 60% and reduces the frequency of manual intervention.
[0063] 2. The present invention is based on the humidity change rate The adaptive dehumidification algorithm reduces energy consumption by 35% while maintaining the humidity in the cabinet in the optimal range of 50% to 60% RH. At the same time, the coordinated design of the nano anti-fingerprint coating and the antibacterial inner layer increases the corrosion resistance of the stainless steel surface by 3 times, with an antibacterial rate of ≥ 99.9%.

[0091] b. Thermal imaging data is normalized to 0-255 grayscale values, marking temperature abnormal areas (temperature difference
[0092] ≥2℃).
[0093] S2. Environmental parameter collection
[0094] (1) The temperature and humidity sensor uses the SHT45 chip, sampling once every 10 seconds, and the data is filtered by Kalman filtering to eliminate noise;
[0095] (2) The VOC sensor uses a PID algorithm to correct the cross-sensitivity of ethanol and formaldehyde, and the output concentration value accuracy reaches ±2ppm.

[0145] b. Secondary verification for sensitive operations: Remote cleaning service reservations require the input of a dynamic verification code (generated via SMS / APP).
[0146] The following is an introduction based on specific embodiments
[0147] Example:
[0148] Scenario description: The user places an unsealed vegetable crisper into a cupboard at an ambient temperature of 28°C and a humidity of 70%.
[0149] 1. Data collection stage:
[0150] 1. The visible light camera detected water mist on the surface of the fresh-keeping box, and the infrared imaging showed that the local temperature was 2°C higher than the surrounding temperature (possibly due to heat generated by vegetable respiration).
[0151] 2. The weight sensor records that the weight of the fresh-keeping box decreases by 8% within 24 hours, indicating that the water evaporates.
[0152] 3. The temperature and humidity sensor detects that the H2O in the cabinet is 72% and the VOC sensor detects that the ethanol concentration has risen to 15 ppm.
[0153] 4. The MOS sensor detected NH3 concentrations up to 12 ppm (released by vegetable spoilage).
[0154] 2. Analysis and Decision-making Stage
[0155] The CNN model identifies mold spots (C1=0.65) and water stains (C2=0.55) in the image and calculates S C =0.6×0.65+0.4×0.55=0.61 (because H>65%, it still triggers a response).
[0156] Corruption Risk Index R d =0.5×28+0.3×72+0.2×0.61=0.8, reaching the threshold.
[0157] The system determines that a three-level response is required:
[0158] Level 1 response: Dehumidification power is increased to 150W + 20 × |(72-65) / 10| = 164W, reducing humidity to 58% within 30 minutes;
[0159] Secondary response: UV-C light irradiates at a wavelength of 270nm for 10 minutes, with a sterilization efficiency of 99.99%;
[0160] Level 3 response: The APP pushes the message "Risk of vegetable corruption detected, it is recommended to clean up immediately and make an appointment for deep cleaning service."
[0161] 3. User Interaction and Optimization
[0162] The OLED screen displays a red warning icon and R d The touch panel provides the options of "dehumidify immediately" and "turn off alarm".
[0163] After the user confirms the service appointment through the APP, the system records the event, and the self-learning algorithm shortens the cleaning cycle of similar scenarios by 20%.
[0164] In addition, when seafood is stored in the cabinet during the rainy season: the system detects H=85% and dH / dt=5% / h, triggering the pre-dehumidification mode: running at 120W power 2 hours in advance to suppress the humidity below 70%; the next day, the camera detects condensation on the cabinet wall, and the self-learning algorithm automatically increases the daily dehumidification benchmark time by 40%, and pushes the "it is recommended to install desiccant" prompt.
[0165] The quantitative comparison of technical advantages is shown in the following table:
[0166] index Traditional solution The present invention Improvement effect Pollution identification response time 8-12 minutes <3 minutes 62.5% speed increase Dehumidification energy consumption (daily average) 2.1kWh 1.4kWh 33.3% reduction Antibacterial rate (72h) 95% 99.9% 5.2 times improvement False alarm rate 15% 4.7% 68.7% reduction
[0167] It can be seen from the table that the present invention can realize full-link closed-loop control from data perception to execution feedback, with high precision, low power consumption and strong robustness.
[0168] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
