[0036] In the above embodiment, the protective shell is made of carbon nanotube reinforced ceramic composite material; the surface of the nano-coated heat sink is covered with an aluminum oxide coating.

[0037] In a specific embodiment, the power supply device 11 provides stable power to the entire system. The thermistor sensor 1, the thermocouple sensor 2, the infrared temperature sensor array 3, the ultrasonic ranging sensor 4, the wind direction sensor 5 and the vibration sensor 6 collect information such as the temperature, distance, wind direction and vibration inside the fan cabin through their respective working principles.

The controller 9 receives the signal of the sensor and judges the working state and environmental conditions inside the fan cabin according to the preset logic. If the temperature exceeds the set range, the controller sends a signal to the micro fan 7 to start the micro fan to reduce the temperature. When the controller sends a signal to start the micro fan, the micro fan starts working and reduces the temperature by generating wind power. Then, the controller 9 sends the temperature information inside the fan cabin to the data display screen 10 so that the operator can monitor and analyze it in real time.

[0038] Embodiment 3: In the above embodiment, the control end of the micro fan 7 is connected to the output end of the controller 9 to control the operating state of the fan; an actuator and a communication interface are provided inside the micro fan 7; the actuator is composed of a thyristor and a power field effect transistor.

[0039] In the above embodiment, the ultrasonic ranging sensor 4 includes an ultrasonic transmitter 401, an ultrasonic receiver 402, a control circuit 403, a time counter 404 and a power module 405; the ultrasonic transmitter 401 and the receiver are located at the front end of the sensor, facing the target to be measured; the control circuit 403 and the time counter 404 are located at the rear end of the sensor, for processing the received signal and calculating the distance; the power module 405 is connected to the control circuit 403 to provide the required power for the entire sensor.

[0040] In a specific embodiment, Figure 3 As shown, the controller 9 sends a control signal to the control end of the micro fan 7 through its output end to control the operating state of the micro fan. An actuator is arranged inside the micro fan 7, and the actuator is composed of a thyristor and a power field effect transistor. Thyristor is an electronic switching device that can control the on and off of current. In the actuator of the micro fan 7, the thyristor plays a role in controlling the current. The power field effect transistor is a high-frequency switching device that can quickly adjust the size of the current. In the actuator of the micro fan 7, the power field effect transistor is used to adjust the size of the current.

[0041] In a specific embodiment of a temperature detection device for fan cabin operation, the controller 9 processes and analyzes the temperature data collected by the sensor. When the temperature exceeds the set threshold, the controller 9 sends a control signal to the micro fan 7. After receiving the control signal, the thyristor and power field effect transistor in the actuator of the micro fan 7 will start to work. The thyristor controls the on and off of the current, and the power field effect transistor adjusts the current size, thereby controlling the speed of the micro fan 7. The micro fan 7 adjusts the speed of the fan blades according to the control signal and the adjusted current to achieve the purpose of temperature control.

By controlling the speed of the micro fan 7, the working state of the fan can be flexibly adjusted according to actual needs, reducing energy consumption and improving energy utilization efficiency. Combined with the controller 9 and the communication interface, remote control of the micro fan 7 can be achieved, which is convenient for operation and management.

[0043] In a temperature detection device for wind turbine cabin operation, an ultrasonic transmitter 401 generates an ultrasonic pulse signal and sends it out. An ultrasonic receiver 402 is used to receive the ultrasonic signal reflected from the target surface. A control circuit 403 is used to control the operation of the ultrasonic transmitter and receiver and process the received ultrasonic signal. A time counter 404 is used to measure the time interval between the transmission and reception of the ultrasonic signal. A power module 405 provides the required power supply for the ultrasonic sensor.

[0044] In a specific implementation, when the ultrasonic transmitter 401 sends out an ultrasonic pulse signal, it will propagate in a specified direction and hit the target surface inside the wind turbine cabin. The target surface will reflect the ultrasonic signal, and a portion of it will be received back by the ultrasonic receiver 402. The received ultrasonic signal is processed by the control circuit 403 to determine the time interval from transmission to reception. The time counter 404 will record this time, so that the round-trip time of the ultrasonic signal can be calculated. According to the speed of ultrasonic wave propagation in the air and the round-trip time, the distance between the target surface and the sensor can be calculated.

[0045] In specific implementation, the ultrasonic sensor can achieve non-contact distance measurement with the target surface, avoiding damage or interference that may be caused by physical contact. In addition, the ultrasonic sensor can achieve high distance measurement accuracy, which can meet the precise distance measurement requirements of the temperature detection device inside the wind turbine cabin. Secondly, the ultrasonic sensor has a fast measurement speed and can obtain the distance information between the target surface and the sensor in a short time, which helps to adjust the temperature control system in time.

[0048] In a specific embodiment, the controller 9 first converts the analog signal from the temperature sensor into a digital signal through an analog-to-digital converter (ADC). The accuracy and sampling rate of the ADC are critical to accurately capture temperature changes. The received digital signal is processed by a processor, which may be a microcontroller or a dedicated digital signal processor. During the processing, filters are used to remove noise, algorithms are used for temperature calibration and correction, and data compression techniques are used to reduce the amount of transmitted data. The processed temperature data is transmitted to a data display screen or other device via a serial communication protocol. Common communication protocols include UART, SPI, and I2C. The choice of which protocol depends on the requirements and performance of the system. The controller 9 executes the corresponding control logic based on the received temperature data. This involves comparing the current temperature with a preset threshold, adjusting the fan speed according to the threshold, turning on or off the heating element, and other operations. The controller uses a PID (proportional-integral-differential) control algorithm to stabilize the temperature within a set range by constantly monitoring temperature changes and adjusting the system. In addition, the controller 9 needs to effectively manage power consumption to extend the battery life of the system or reduce grid electricity costs. This involves sleep mode, dynamic voltage regulation, and power management technology. The controller integrates a voltage regulator and a DC-DC converter to ensure that all parts of the system can operate at a stable voltage while minimizing power consumption losses. In addition, the controller 9 includes fault detection functions, such as detecting sensor failure or communication interruption, and taking appropriate measures, such as switching to a backup sensor or sounding an alarm. To ensure the integrity and reliability of data transmission, the controller 9 uses CRC (cyclic redundancy check) error detection and correction technology.
