DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-12 The present application provides a technical solution: a fan with alarm function, comprising:

[0037] The lightning protection anti-static surge module 1 is connected to the power input end of the fan, and resists lightning, static discharge, power surge and other extreme voltage fluctuations.

[0038] Specifically, the protection circuit can quickly respond to and absorb or shunt these abnormal voltage energy, thereby ensuring that the heat dissipation fan can still operate stably in a complex and changeable electrical environment, significantly improving its working reliability and service life.

[0039] The main power management module 2 is connected to the fan and provides voltage supply suitable for the working characteristics of various chip elements;

[0040] Compared with the traditional single power supply design scheme, the dual-path main power supply configuration significantly reduces the load pressure of the power management chip, effectively disperses the current, and thereby reduces the heating phenomenon of the chip itself, thereby improving the operating efficiency and stability of the entire control circuit;

[0041] In addition, in view of the possible large fluctuations and unstable factors of the input voltage, the LM7805 power management chip is carefully selected on the 5V power supply output circuit. The chip has excellent wide input capability (6-35V) and stable 5V / 1A output characteristics, which ensures that even in an environment with large input voltage fluctuations, the subsequent control circuit can be provided with continuous and stable power supply. This design not only enhances the environmental adaptability of the system, but also lays a solid foundation for the long-term stable operation of the heat dissipation fan;

[0042] The temperature linkage rotation speed module 3 monitors the ambient temperature, monitors the fan rotation speed and controls the fan rotation speed, and through precise circuit logic architecture design and operation optimization, the fan operates stably in the optimal rotation speed interval;

[0043] The circuit carefully integrates DS18B20 high-precision digital temperature sensor, programmable digital potentiometer and high-performance secondary signal processor and other core components, and through precise circuit logic architecture design and operation optimization, the mechanism can ensure that the heat dissipation fan operates stably in the optimal rotation speed interval, thereby effectively protecting the heat dissipation efficiency of the equipment and significantly prolonging the service life of the fan;

[0044] Specifically, when the DS18B20 temperature sensor accurately captures that the ambient temperature exceeds the preset safety threshold, the temperature monitoring circuit will immediately respond and activate the fan rotation speed control circuit through a complex signal processing process. This response mechanism prompts the fan to quickly switch to a high-performance operation mode, significantly improves the air exhaust capacity and heat dissipation efficiency, and achieves rapid and efficient cooling effect. On the contrary, once the temperature sensor detects that the ambient temperature has fallen within the preset safety range, the temperature monitoring circuit will intelligently adjust the fan rotation speed to the energy-saving mode, thereby maintaining the appropriate heat dissipation conditions while realizing the rationalization control of energy consumption.

[0045] The sound abnormality monitoring module 4 monitors the abnormal sound emitted by the fan;

[0046] In the design process of the heat dissipation fan of the application, various potential failure conditions are considered in depth, including but not limited to foreign matter intrusion into the fan blade area, severe wear of the fan assembly due to long-term use to the end of the design life, and abnormal contact between the fan blade and the shell induced by other unknown factors, which can cause abnormal sound during fan operation. In order to accurately monitor the abnormal sound of the fan caused by the above factors, the application innovatively integrates advanced sound anomaly detection circuit system;

[0047] The core components of the system are selected as high-performance audio sensing elements as pickup sensors, and high-stability and reliable operational amplifier integrated circuits. This design realizes the first-stage preliminary amplification processing of the sound signal through a fine circuit architecture, followed by two-stage precise signal amplification, and integrates complex operation processing circuits to ensure accurate collection and efficient identification of the sound signal. This series of signal processing procedures not only improves the sensitivity and accuracy of abnormal sound detection, but also effectively avoids the blind area and subtle fault points that are difficult to detect by manual detection.

[0048] Through this innovative sound anomaly detection system, any abnormal sound signs during fan operation can be captured and identified in real time, and warning signals can be sent to the management personnel in time, so as to greatly advance the timing of fault discovery and processing. This mechanism is of great significance to maintain the safe and stable operation of production equipment, ensure the continuity of production process and the high reliability of product quality, realizes intelligent monitoring and management of the state of the heat dissipation fan system, and promotes significant improvement of overall operation and maintenance efficiency and safety guarantee level.

[0049] The wireless alarm module 5 acquires the data of the temperature linkage speed module 3 and the sound anomaly monitoring module 4, and the wireless alarm module 5 alarms the high temperature, abnormal sound, low speed and power failure of the fan;

[0050] The reference point standard module 6 is connected to the main power management module 2, and the reference point standard module 6 provides accurate and accurate execution signal processing for the subsequent monitoring circuit;

[0051] Therefore, the product specially designs a set of independent reference point standard circuit in the power management design part. The circuit not only has high stability, but also provides a pure and accurate reference voltage source for the entire monitoring circuit by introducing TL431, a high-performance reference voltage chip. TL431 ensures the constancy and reliability of the reference point voltage with its excellent temperature stability and low noise characteristics, thereby effectively improving the signal processing accuracy and stability of the monitoring circuit.

[0052] Through the innovative design, the heat dissipation fan product realizes significant performance improvement in signal processing, the processing circuit part can stably and accurately process various monitoring signals based on a stable and accurate reference point voltage, further enhances the overall performance and monitoring accuracy of the product, which not only embodies the deep technical accumulation of the product in the field of power management and signal processing, but also provides strong technical support for the accurate monitoring and efficient operation of the heat dissipation fan.

[0053] The main power management module 2 includes a 5V main power unit 21 and a 3.3V main power unit 22, the 5V main power unit 21 provides a 5V working voltage, and the 3.3V main power unit 22 provides a 3.3V working voltage.

[0054] The temperature linkage rotating speed module 3 includes a temperature monitoring unit 31, a rotating speed monitoring unit 32, a fan rotating speed control unit 33 and a fan air volume control unit 34, the temperature monitoring unit 31 monitors the ambient temperature, the rotating speed monitoring unit 32 monitors the fan rotating speed, the fan rotating speed control unit 33 controls the fan rotating speed, and the fan air volume control unit 34 controls the fan air volume.

[0055] The main power management module 2 is connected with a power failure monitoring unit 23, which monitors the power failure of the fan.

[0056] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
