This not only improves the efficiency of the experiment, but also provides technical support for further microbial classification and diagnosis.

[0137] The specific implementation scheme of the present invention is as follows:

[0138] 1. Intelligent environmental control system combined with machine learning algorithm to achieve optimal control model

[0139] Data collection and preprocessing: The internal environment of the culture device is monitored in real time through the precision sensors in the device (temperature sensor, humidity sensor, carbon dioxide concentration sensor, etc.), and the temperature, humidity, gas concentration and other parameters are collected at intervals of 1 minute and stored in the database. The data of each collection point includes the current environmental parameters and the corresponding microbial growth results.

[0140] Model training: Use historical environmental data to train a prediction model through supervised learning algorithms in machine learning, such as linear regression, random forest, or XGBoost algorithms. The goal of the model is to generate the optimal environmental parameter settings to ensure the most ideal growth conditions for microorganisms. The input data is the environmental parameters and the output is the corresponding growth results.

[0141] Dynamically adjusted feedback control: After the trained model is embedded in the control system, the feedback control system will dynamically adjust the heating device, humidification device and gas input module based on the current sensor data and the model's recommendations to ensure that the system can maintain the optimal environment. By continuously learning new data, the model will automatically update to achieve more precise control.

[0142] 2. Real-time image monitoring and analysis system uses deep learning for colony detection and classification

[0143] Image acquisition: The high-definition camera in the device will take pictures of the microorganisms in the culture dish at fixed intervals (e.g. every 10 minutes). The captured images will be transmitted to the image processing module in real time.

[0144] Data processing and feature extraction: The image processing system extracts features of colonies based on convolutional neural networks (CNN). The algorithm automatically identifies features such as the boundaries, morphology, and color of colonies, and determines the growth morphology of colonies through pixel-level classification models. The network model has been trained with a large amount of microbial sample data and can accurately distinguish different types of colonies.

[0145] Colony detection and classification: The system clusters and classifies multi-dimensional image features, and uses trained deep learning models (such as ResNet and MobileNet) to analyze the number, size, shape, and growth rate of colonies. Based on the results output by the model, it can be determined in real time whether the growth status of microorganisms is normal.

[0146] Abnormal detection and alarm: The system sets a standard threshold for colony growth. If it detects abnormal growth of some colonies (such as slow growth, inconsistent morphology, etc.), the system will automatically send out an alarm signal and generate a detailed analysis report. The report includes the abnormal performance of the colony, the test data and the recommended treatment methods for the experimenter to refer to and take countermeasures.

[0147] 3. Implementation process of automatic sample processing and operating system

[0148] Sample injection and culture medium addition: At the beginning of the experiment, the automatic sample handling module accurately injects the sample into the culture dish through the robotic arm and automatically adds the corresponding culture medium. This process is controlled by the system to ensure accurate sample injection and uniform distribution of the culture medium.

[0149] Petri dish handling and automatic disinfection: After the sample is injected, the robot will automatically place the petri dish containing the sample on the culture rack and move it to the corresponding culture position according to the experimental plan. After the operation is completed, the device will automatically disinfect the culture area and the petri dish to avoid cross contamination.

[0150] Parallel processing of multiple samples: By setting the path planning of the robot, the system can process multiple samples at the same time. The robot completes the injection, cultivation and handling of each sample in sequence according to the preset batch control strategy, thereby greatly improving the experimental efficiency.

[0151] 4. Implementation of the rapid detection module

[0152] Microfluidic detection: The system uses microfluidic technology to monitor changes in metabolites in the culture medium at the beginning of the culture, such as using built-in optical sensors to detect changes in color or turbidity in the culture medium in real time. The sensor will perform a rapid test every few minutes to analyze the activity of the microorganisms in real time.

[0153] Data feedback and rapid analysis: The data collected by the sensor will be processed by the built-in analysis module. If significant changes in the culture solution (such as increased turbidity or color change) are detected, the system will immediately determine the growth status of the microorganism. Compared with traditional culture methods, this module can obtain information on the activity of microorganisms several hours in advance.

[0154] Specific marker detection: Combined with the chip of microfluidic technology, the system can determine whether there is a specific microbial community in the culture medium through marker detection. It is suitable for rapid screening and classification of different microbial species, providing important data for subsequent analysis.

[0164] - Heater, humidifier 7:

[0165] The heater adopts a PTC heating element (for example, model PTC100W), and controls the heating amount through a feedback system to maintain a constant temperature; the humidifier adopts an ultrasonic atomizing humidifier (for example, model UHF-10), and controls the humidity by adjusting the amount of water mist.

[0166] -Gas input module 8:

[0167] An electric regulating valve and a gas mixer (such as the GFC17 model) are used to control the gas concentration in the chamber and precisely adjust the mixing ratio of oxygen and carbon dioxide to ensure a gas environment suitable for specific microorganisms.

[0168] -Data recording and optimization module 9:

[0169] By connecting the storage module to the database, all environmental parameter data are uploaded to the cloud database via the Wi-Fi module and a historical curve is generated. Users can view it through the web or mobile device. The system will automatically analyze the data and provide optimization suggestions.

[0170] 3. Implementation of the automatic sample processing and operation system 2

[0171] The automatic sample processing system is designed to fully automatically complete sample processing and operation, avoiding human intervention.

[0172] - Sample injection and culture medium addition:

[0173] The sample and culture medium injection process is controlled by a robotic arm (such as KUKA KR 3AGILUS) and a high-precision syringe pump (such as PHD ULTRA). The robotic arm moves along a preset trajectory, accurately injects the sample into the culture dish, and adds culture medium to the culture dish through a liquid handling module.

Image analysis software analyzes the size, morphological changes, and growth rate of the colonies and visualizes the results. -Automatic alarm system:

[0184] When the system detects abnormal growth patterns (such as excessive colony density, abnormal morphology, etc.), it will automatically send an alarm signal and generate a detailed growth report for user reference.

[0185] 5. Implementation of Rapid Detection Module 4

[0186] The rapid detection module uses microfluidics technology and optical sensors to quickly evaluate the growth status of microorganisms.

[0187] -Microfluidic chip:

[0189] -Optical Sensor:

[0190] Optical sensors (such as LED and photodiode combinations) are used to detect changes in the color and turbidity of the culture solution. The growth of different microorganisms will cause different changes in the color or turbidity of the culture solution. The sensor can feedback these changes in real time and derive microbial activity through algorithm analysis.

[0191] Data output and rapid detection:

[0192] The system can determine whether the microorganisms are growing normally based on the changes in metabolites at the early stage of microbial cultivation. The rapid detection module can generate a preliminary report within just a few hours after the start of cultivation, significantly shortening the time required for traditional microbial culture detection (usually more than 24 hours).

[0193] 6. User interface and operation management

[0194] -Touch operation interface:

[0195] The device is equipped with a 7-inch touch screen interface (such as Raspberry Pi Touch Display), which allows users to view data such as culture status, environmental parameters, image analysis results, etc. in real time. The operation interface is simple and clear, allowing users to set different experimental plans and adjust parameters.

[0196] Remote monitoring and control:

[0197] Through Wi-Fi or Ethernet connection, users can remotely monitor and manage the device through mobile phones and computers. The system supports remote fault diagnosis and automatic maintenance prompts to ensure long-term stable operation of the equipment.

[0198] Through the above scheme, the microbial detection and cultivation device can achieve highly automated and intelligent microbial cultivation and detection, reduce manual intervention, and improve detection efficiency. It is suitable for hospitals, laboratories, and large-scale industrial detection scenarios. Especially in large-scale microbial detection, such as food safety, drug testing, and infectious disease detection, the device can provide fast and accurate cultivation and detection results, significantly improving experimental efficiency.
