[0037] The communication device is used to realize information transmission between the controller body 11 and the heating element 13. It can be wireless or wired to ensure stable communication between the controller body 11 and the heating element 13.
[0038] The control logic of the controller body 11 is designed for data acquisition and processing, using filtering algorithms to reduce noise and improve data quality. The controller body 11 incorporates an advanced PID control algorithm to dynamically adjust the power output of the heating element 13 based on the deviation between the real-time temperature and the preset target temperature.

[0039] Reference Figure 2 This application embodiment utilizes the above system to implement a controller temperature management method in a low-temperature environment, the method comprising the following steps:
[0040] The real-time operating temperature of the controller body 11 is monitored in real time using temperature sensor 12;
[0041] The controller body 11 receives the real-time operating temperature collected by the temperature sensor 12 and analyzes it according to the preset temperature threshold (such as -40°C) and the trend of change.

[0043] The system described in this application enables real-time monitoring and intelligent adjustment of the controller temperature, improving the stability and reliability of the controller in low-temperature environments; by intelligently adjusting the power and working time of the heating element 13, energy consumption is reduced and energy efficiency is improved; the system design is flexible and can be adjusted according to different application scenarios and needs, making it widely applicable.
[0044] The controller temperature management system described in this embodiment for low-temperature environments can be applied in various scenarios. For example, in scenario 1 of a communication base station within the Arctic Circle, the electronic controller of this base station needs to maintain stable operation in extreme low-temperature environments. To address this challenge, a temperature management system for a communication base station within the Arctic Circle was designed and deployed to ensure that the controller can still operate reliably at extreme temperatures of -60°C.
[0045] The core of the temperature management system for communication base stations within the Arctic Circle is a set of high-precision digital temperature sensors 12, which are deployed on key thermal nodes of the controller, including the CPU, memory modules, and I / O interfaces. These digital temperature sensors 12 are connected to a central data acquisition device via a multiplexer, which transmits temperature data to the controller body 11 via SPI signals.
[0046] The controller body 11 uses an ARM Cortex-M4 microcontroller with a built-in real-time operating system, which can execute complex control algorithms and dynamically adjust the power of the heating element 13 according to real-time temperature data.
[0047] The heating element 13 itself is a thin, high-efficiency electrothermal film, tightly fitted inside the controller housing. Through the PWM output of the controller body 11, the electrothermal film can precisely adjust its heating power to adapt to constantly changing temperature conditions. For remote monitoring and control, the controller body 11 is connected to the base station's local area network via a wireless Wi-Fi module, allowing operators to access a web-based graphical user interface from any device connected to the local area network.
[0048] After deploying the temperature management system for the communication base station within the Arctic Circle, the inventors conducted a series of tests, including sensor accuracy testing, controller response time 11 testing, and heating element 13 power adjustment range testing. These tests ensured the reliability and accuracy of the temperature management system in actual operation. The control logic of the temperature management system for the communication base station within the Arctic Circle employs an advanced PID algorithm, automatically adjusting the power and operating time of the heating element 13 based on preset temperature thresholds and temperature data fed back from the sensors. For example, if the CPU temperature drops below -40°C, the temperature management system will automatically increase the heating power to rapidly raise the temperature until it returns to a safe range.
[0049] The temperature management system for the communication base station within the Arctic Circle also features self-diagnostic capabilities, monitoring the status of sensors and the controller unit 11. If any anomaly is detected, such as sensor failure or controller unit 11 malfunction, the system will send alarm notifications via GUI and email, ensuring timely operator response. Furthermore, the system records energy consumption for each heating event and analyzes energy consumption patterns to optimize heating strategies and reduce unnecessary energy consumption.
[0050] Based on the collected data, the inventors also optimized the control parameters using machine learning algorithms, enabling the temperature management system of the communication base station within the Arctic Circle to adapt to the varying temperature conditions within the Arctic Circle. This not only improved the energy efficiency of the temperature management system of the communication base station within the Arctic Circle but also enhanced its adaptability and stability in extreme environments. Finally, the inventors provided a detailed system maintenance manual and software upgrade guide to ensure long-term stable operation of the system, and conducted continuous operation testing for up to 6 months under the extreme low temperatures of the Arctic Circle, further verifying the system's stability and reliability.
[0051] The temperature management system of this communication base station in the Arctic Circle demonstrated its efficient, energy-saving, and intelligent temperature control capabilities in extreme low-temperature environments, ensuring the stable operation of the communication base station controller and proving its practical value in similar application scenarios.
[0052] The controller temperature management system in the low-temperature environment described in this embodiment can also be used for temperature management in high-altitude wind turbine controllers. In this scenario 2, a temperature management system for a high-altitude wind turbine controller is provided.
[0053] Due to its geographical location, the wind turbine is frequently subjected to severe weather conditions such as extreme low temperatures and strong winds, which poses a serious challenge to the stable operation of the controller.
[0054] The design of the temperature management system for the high-altitude wind turbine controller began with a detailed analysis of the controller's thermal characteristics to identify critical thermal nodes. A series of high-precision, weather-resistant digital temperature sensors12 were installed on the controller's CPU, power module, and key interface cards. These sensors are connected via a robust cable bundle to a centralized data acquisition module, which is designed to be waterproof and dustproof to withstand harsh outdoor environments.
[0055] The data acquisition module collects temperature data in real time and transmits it to the controller body 11 via a stable RS-485 communication link. The controller body 11 employs a high-performance ARM Cortex-A series microcontroller, which not only possesses powerful data processing capabilities but also incorporates advanced control algorithms. The control algorithm dynamically adjusts the power of the heating element 13 based on the real-time temperature data to maintain the controller within its optimal operating temperature range. The heating element 13 uses flexible heating plates, which can be customized to fit the geometry of the controller housing and are installed inside the housing. Through precise PWM signal control by the controller body 11, the heating plates can provide heat evenly, preventing localized overheating or uneven temperature distribution.
[0056] To enable remote monitoring and control, the controller body 11 incorporates a wireless communication module that supports multiple wireless protocols, including cellular networks, Wi-Fi, and satellite communication. This allows operators to remotely monitor the system status from the control center and intervene when necessary. The temperature management system of the high-altitude wind turbine controller also includes a user-friendly web interface that provides real-time temperature monitoring, historical data analysis, and system configuration functions. Operators can access this interface using any device with a web browser, whether at the control center or on-site.
[0057] Prior to deploying the temperature management system for the high-altitude wind turbine controller, the inventors conducted a series of field tests, including testing the accuracy and response time of the sensors under simulated extreme low-temperature conditions, and testing the communication reliability of the data acquisition module under strong wind conditions. The test results demonstrated the system's robustness and reliability. Furthermore, the temperature management system for the high-altitude wind turbine controller integrates an adaptive learning algorithm that automatically optimizes control parameters based on historical temperature data and environmental conditions, further improving energy efficiency and system responsiveness.
[0058] The temperature management system of this high-altitude wind turbine controller not only ensures the stable operation of the wind turbine controller in harsh environments, but also improves the system's energy efficiency and ease of operation through intelligent control.
[0059] The controller temperature management system described above in this embodiment can also be used for the temperature management of deep-sea oil drilling platform controllers, thereby providing an extreme temperature adaptability management system for deep-sea oil drilling platform controllers.
[0060] First, we conducted a detailed thermodynamic analysis of the controller body 11 to identify the components most likely to experience performance issues under the extreme low temperatures of the deep sea. On these critical components, we installed a series of specialized temperature sensors 12, which not only withstand the high-pressure environment of the deep sea but also possess excellent low-temperature measurement performance.
[0061] These temperature sensors 12 transmit data via a robust fiber optic communication link. This link not only has strong anti-interference capabilities but also provides stable signal transmission, making it suitable for long-distance and harsh environment data transmission. The data is ultimately transmitted to a central controller 11, which employs a high-performance microcontroller with built-in sophisticated control algorithms. This controller can respond to sensor data in real time and adjust the operating state of the heating elements 13. The heating elements 13 are made of a special conductive polymer material, which not only has high heating efficiency but also adheres evenly to the surface of the controller 11, ensuring uniform temperature distribution throughout the device. The controller 11 dynamically adjusts the power output of the heating elements 13 using precise PWM control signals to achieve accurate temperature control.
[0062] To enable remote monitoring and control of the extreme temperature adaptability management system of the deep-sea oil drilling platform controller, a satellite communication module is integrated into the controller body 11. This allows operators to monitor the system status in real time and respond quickly to anomalies, even in remote areas like the deep sea. Furthermore, the extreme temperature adaptability management system of the deep-sea oil drilling platform controller is equipped with a high-level user interface. This interface not only provides real-time temperature monitoring and historical data recording functions but also allows users to customize temperature control strategies based on current operating conditions and environmental parameters.
[0063] Before deploying the extreme temperature adaptability management system for the deep-sea oil drilling platform controller, the inventors conducted rigorous testing on the entire system in a simulated deep-sea environment, including sensor stability testing, communication link reliability testing, and heating performance testing of the heating element 13. The test results show that the extreme temperature adaptability management system for this deep-sea oil drilling platform controller can operate stably in extreme deep-sea environments, ensuring the reliability of the drilling platform controller body 11.
[0064] The extreme temperature adaptability management system of this deep-sea oil drilling platform controller demonstrates its application potential in extreme deep-sea environments, providing a powerful temperature control solution for deep-sea oil drilling operations.
