[0064] Example 2: Reference Figure 9In a second embodiment of the present invention, the present invention provides an intelligent automatic control cabinet operation method, comprising the following steps: S1: System initialization. After the power is turned on, the main control module initializes each functional unit, including the processing unit, storage unit, and communication module, and detects whether the power input voltage and communication link are normal; S2: Data acquisition, the input and output module receives external sensor signals, the analog signals are processed by the signal conditioning circuit and then input into the main control module, and the digital signals are directly transmitted to the main control module through the optoelectronic isolation circuit; S3: Data processing and judgment: the main control module filters, linearizes and detects abnormal values ​​on the collected data, and determines whether to trigger the output according to the preset logic; S4: Control signal output. The output unit generates a control signal according to the instructions of the main control module, including switch output, analog output or PWM output, to drive the actuator to complete the predetermined operation.

If an overload, short circuit or over-temperature abnormality is detected, the power supply will be immediately cut off and an alarm will be triggered.

[0065] Specifically, S1, system initialization After the system starts, the system is initialized first to ensure that all modules are ready.

[0066] Power on: After the system is powered on, the power module provides stable power to the main control module and various submodules. The power module first converts the input AC power into DC power through an AC / DC converter. Then, it uses a DC-DC converter to generate multiple voltages (such as 12V, 5V, and 3.3V) to supply each module.

[0067] Initialize the main control unit: The main control unit (STM32 microcontroller) performs self-tests and initialization. Its built-in watchdog timer checks whether the system has booted successfully and initializes the peripherals, including the storage unit, communication interface, and input and output units.

[0068] Detect power supply and communication links: The voltage detection unit monitors whether the input voltage is stable and sends feedback signals to the main control unit; the communication module checks whether the network connection is normal to ensure that subsequent data transmission is correct.

[0069] The system initialization step ensures that each module can start smoothly, and improves the reliability and stability of the system by detecting the status of the power supply and communication link in real time.

[0070] S2. Data Collection and Processing Data acquisition is a core step in system operation, which involves collecting data from external sensors and processing them in real time.

[0071] Collecting sensor data: The input and output modules receive signals from external sensors to collect various sensor data, including temperature, humidity, pressure, flow, voltage, and current. Analog signals are amplified and filtered by signal conditioning circuits, while digital signals are electrically isolated by optoelectronic isolators.

[0072] Signal conversion and processing: The collected analog signals are digitized by the analog-to-digital converter (ADC) of the main control unit, and the input temperature sensor signals (such as thermocouples and RTD signals) are further converted by the signal conditioning module (such as MAX31855 and AD8495).

[0073] Data preprocessing and filtering: The main control unit uses algorithms such as Kalman filtering to filter and denoise the collected data to remove possible errors and fluctuations and ensure data accuracy.

[0074] Through precise data collection and processing methods, the system can efficiently and accurately obtain the status of the external environment and equipment, providing reliable data support for subsequent control decisions.

[0075] S3. Data Analysis and Decision-making The main control unit analyzes the collected data in real time and determines whether control operations are required based on a preset algorithm.

[0076] Data analysis and judgment: The main control unit analyzes the collected signal data to check whether it meets the set operating standards (such as whether the temperature is within the safe range, whether the current is overloaded, etc.). If the data exceeds the threshold, the main control unit will generate an alarm message.

[0077] Intelligent Decision-Making: The main control unit determines whether to start or stop an external device based on analysis results and pre-defined control logic (such as PID control and threshold judgment). For example, if the temperature exceeds a safe range, the system automatically activates the cooling device; if the current is overloaded, the system immediately cuts off the power supply.

[0078] Data analysis and intelligent decision-making ensure that the system responds according to preset rules and real-time data, achieving efficient and intelligent automated control. This process greatly improves the system's adaptability and enables it to react quickly to different input signals.

[0079] S4, control signal output According to the decision of the main control unit, the control signal is transmitted to the output unit to perform the corresponding operation.

[0080] Output control signals: The output unit receives commands from the main control unit and generates control signals. For example, if the main control unit issues a command to turn on a motor, valve, or relay, the output unit drives these devices through MOSFETs or relays.

[0081] Analog or PWM output: For devices that require adjustment, the output unit uses analog signals (such as 0-10V) or PWM signals to precisely control the device's operating state. For example, adjusting the speed of a servo motor or the brightness of an LED.

[0082] Control signal output ensures that the device executes operations precisely according to the instructions of the main control unit, providing efficient and precise control capabilities. The output module is designed to support multiple signal types to meet the needs of different devices and enhance system flexibility.

[0083] S5. Data communication and synchronization The data communication module enables data interaction between the system and remote devices or cloud platforms, supporting remote monitoring and control.

[0084] Local data synchronization: Through wired or wireless communication modules, the system uploads locally collected data to the cloud or host computer for remote operators to view and analyze.

[0085] Remote control: Users send commands to the control cabinet via a remote terminal (such as a computer or mobile device). The system then executes the corresponding operation upon receiving the command. During data transmission, encryption protocols (such as SSL / TLS) are used to protect data security and prevent data leakage or tampering.

[0086] Through real-time data synchronization and remote control functions, the system can achieve remote monitoring and management, greatly improving the convenience and flexibility of operation. Data encryption ensures the security of communication and avoids potential security risks.

[0087] S6. User interaction and operation The user interaction module allows users to easily view system status, set parameters and perform operations through an intuitive interface.

[0088] Display interface presentation: The system displays real-time data, alarm information, historical data, etc. to users through a touch screen or graphical display interface. Users can view the operating status of the equipment and perform setting operations through the touch screen.

[0089] User input instructions: Users input operating instructions through the touch screen, such as starting and stopping the equipment, adjusting parameters, etc. In an emergency, the user can cut off the power supply through the emergency stop button to ensure the safety of the equipment.

[0090] The user interface uses a graphical display to make operation simple and intuitive, reducing the complexity of the use process. At the same time, the emergency stop function provides system safety protection and enhances system reliability.

[0091] S7. Anomaly detection and protection The protection module monitors the system's operating status in real time and takes timely measures when a fault or abnormal situation occurs.

[0092] Abnormality detection: The system monitors the status of equipment in real time through various sensors (such as temperature sensors and current sensors). When an abnormality such as overload, short circuit, or overtemperature is detected, the main control unit triggers a protective action.

[0093] Protection action: When a fault occurs, the system immediately disconnects the relevant circuit to prevent equipment damage. For example, when the current is overloaded, the system automatically disconnects the power supply; when the temperature is too high, the system starts cooling the equipment or stops working.

[0094] Abnormal detection and protection mechanisms effectively prevent equipment damage and improve system security and stability. Automated protection measures reduce the need for human intervention and improve the system's intelligence.
