[0043] In a preferred embodiment of the present application, the system further comprises a remote monitoring and diagnostic system for supporting real-time monitoring, fault diagnosis, performance analysis and software updates and allowing remote access by technical support personnel.
[0044] And, according to the application of the above-mentioned adaptive ambient temperature control system in automatically adjusting the temperature of the target device; the specific application method is:
[0045] S1. Install temperature monitoring units (temperature sensors and data output devices) at key locations of target equipment that require temperature control, such as the air inlet, air outlet, cable connection area, and hot spots in the cabinet, to accurately measure, record, and output temperature data, ensuring that the system can fully monitor the internal and external environment of the equipment;
[0046] S2. The temperature data output by the temperature sensor is transmitted to the intelligent control unit via a wired (such as RS-485 bus) or wireless (such as Wi-Fi or Bluetooth) output device. The selected communication method should ensure the reliability and real-time performance of data transmission.
[0047] S3.

[0048] S4. Based on the decision of the intelligent control unit, the dynamic adjustment execution unit automatically adjusts the working state. For example, when the internal temperature rises, the variable speed fan system speeds up and the PCM cooling module starts to absorb heat. If the temperature continues to rise, the thermoelectric cooling module starts to provide additional cooling.
[0049] S5. User Interaction: Users can monitor system status in real time through an intuitive user interface, including temperature readings, equipment operating status, and energy consumption data. Users can also set temperature thresholds, adjust control parameters, or manually override the automatic control system as needed.
[0050] S6. Energy efficiency optimization: The energy efficiency management module continuously analyzes the system's operating data, learns the user's operating habits and environmental changes, and automatically adjusts the control strategy to optimize energy consumption. For example, the system can reduce the fan speed during off-peak hours or adjust the working mode of the thermoelectric cooling module.
[0051] S7. Remote monitoring and maintenance: The remote monitoring and diagnostic system allows technical support personnel to remotely access the temperature control system of the intelligent low-voltage cabinet through a secure network connection. Technicians can monitor the system status in real time, perform fault diagnosis, update system software, or remotely adjust the control strategy when necessary.

[0053] S9. User training and documentation: Provide users with detailed operation manuals and maintenance guides, including guidance on system configuration, troubleshooting, and performance monitoring. At the same time, provide training and technical support to ensure that users can fully utilize the functions of the system.
[0054] S10. Continuous Improvement: Based on user feedback and system operation data, continuously optimize system performance, update control algorithms, improve user interfaces, and enhance the functions of remote monitoring and diagnostic systems.
[0055] The following will take the intelligent low-voltage cabinet as an example to explain in detail the working method of the adaptive ambient temperature control system described in this application.
[0056] Example 1
[0057] S1. System composition and unit settings
[0058] (1) Temperature monitoring unit: Install high-precision, high-sensitivity temperature sensors and data output devices at key locations such as the air inlet, air outlet, cable connection area, and hot spots in the intelligent low-voltage cabinet. The PT100 temperature sensor has a measurement accuracy of ±0.15°C and can accurately sense temperature changes and transmit data to the intelligent control unit in real time via the RS-485 bus.
[0059] (2) Intelligent control unit: It uses a high-performance microprocessor, such as the ARM Cortex-M4 series chip, which has powerful data processing capabilities and a built-in fuzzy logic control algorithm. It can accurately predict the temperature change trend based on the data transmitted by the temperature monitoring unit, and make adjustment decisions based on the temperature threshold set by the user, and transmit the decision to the dynamic adjustment execution unit.
[0060] (3) Dynamic adjustment unit:
[0061] Variable speed fan system: It is composed of multiple variable speed fans. The fan motor adopts a brushless DC motor, which can achieve stepless speed adjustment through PWM (pulse width modulation) signal. The speed range is 500-3000rpm.
[0062] Phase change material heat dissipation module: PCM material with a phase change temperature of 30℃-35℃ and a phase change latent heat of about 200kJ / kg is selected to effectively smooth temperature fluctuations.
[0063] Thermoelectric cooling module: It starts automatically when the temperature reaches 50°C and uses the Peltier effect for cooling, with a maximum cooling power of up to 100W.
[0064] (4) User interaction interface: It is integrated into the operation panel of the intelligent low-voltage cabinet and is a 7-inch color touch screen. The interface displays real-time temperature curves (using different color lines to display temperature changes in different areas of the cabinet), system operation status (fan speed, thermoelectric cooling module working status, etc.), historical temperature data (temperature changes in the past week can be queried), and energy consumption statistics charts (energy consumption data is displayed by day, week, and month). Users can set temperature thresholds through the touch screen, for example, setting the upper limit of the temperature to 40°C and the lower limit to 10°C. They can also manually adjust the fan speed or turn on / off the thermoelectric cooling module.
[0065] (5) Energy efficiency management module: records the operating status information such as the operating time and load rate of the intelligent low-voltage cabinet, as well as historical energy consumption data. By analyzing the user's demand for temperature control in different time periods (such as weekdays, nights, weekends, etc.), the temperature control strategy is automatically optimized. For example, when the load is low and the ambient temperature is low at night, the fan speed is appropriately reduced to reduce energy consumption.
[0066] (6) Remote monitoring and diagnostic system: By connecting to the enterprise internal network through the Ethernet interface, technical support personnel can use dedicated software to remotely access the temperature control system of the intelligent low-voltage cabinet. The software interface displays real-time temperature, system operating parameters, fault alarm information, etc., and can remotely update the control algorithm and system software.
[0067] S2. System adaptive ambient temperature control process:
[0068] (1) Initial state: Assume that the ambient temperature of the intelligent low-voltage cabinet is 25°C, the equipment in the cabinet is operating normally, the temperature monitoring unit monitors the temperature in real time, the intelligent control unit is in standby state, the variable speed fan runs at the minimum speed of 500 rpm, the phase change material heat dissipation module is in normal state, and the thermoelectric cooling module is not started. The user interaction interface shows that the current temperature is 25°C, the system is operating normally, and the energy consumption is at a low level.
[0069] (2) Temperature rise stage: As the ambient temperature rises and the load of equipment in the cabinet increases, the temperature in the cabinet gradually rises. When the temperature reaches 35°C (close to the upper limit of 40°C set by the user), the temperature monitoring unit transmits the data to the intelligent control unit. After analyzing the data, the intelligent control unit determines that the temperature has a trend of continuing to rise based on the built-in algorithm, and sends a command to the variable speed fan system to increase the fan speed to 1500rpm to enhance the heat dissipation effect. At this time, the fan speed display on the user interaction interface changes to 1500rpm, and the temperature curve shows a trend of rising temperature, but it is still within the controllable range.
[0070] (3) High temperature response stage: If the ambient temperature continues to rise and the temperature inside the cabinet reaches 42°C, the intelligent control unit analyzes the data again and determines that fan heat dissipation alone can no longer meet the demand, so it starts the thermoelectric cooling module. At the same time, the variable speed fan speed is further increased to 2500rpm, and the phase change material heat dissipation module also absorbs heat with all its strength. The status of the thermoelectric cooling module on the user interface is displayed as "on", the temperature curve shows that the temperature rise trend slows down, and the energy consumption data begins to increase.
[0071] (4) Temperature drop phase: After a period of cooling and heat dissipation, the temperature inside the cabinet begins to drop. When the temperature drops to 38°C, the intelligent control unit gradually reduces the fan speed to 1500 rpm based on the temperature change trend and the pre-set strategy, and keeps the thermoelectric cooling module running for a period of time to ensure that the temperature drops steadily. The temperature curve on the user interface shows that the temperature is dropping, and the fan speed is reduced accordingly.
[0072] (5) Normal recovery stage: When the temperature inside the cabinet drops below 30°C, the intelligent control unit determines that the system has returned to normal, turns off the thermoelectric cooling module, adjusts the fan speed back to the minimum speed of 500 rpm, and the phase change material heat dissipation module returns to normal. The user interface shows that the system status has returned to normal and the energy consumption has dropped to the initial level.
[0073] Throughout the process, the energy efficiency management module continuously records and analyzes system operation data, and automatically optimizes the temperature control strategy according to changes in ambient temperature and equipment load. For example, during the temperature drop, if it is judged that the ambient temperature is low at night and the equipment load is small, the fan speed will be reduced in advance to further reduce energy consumption. The remote monitoring and diagnosis system transmits system status information to the technical support center in real time, and technicians can check the system operation status at any time. If an abnormality is found, remote diagnosis and processing can be carried out in time.
[0074] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
