Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a device power supply, an electronic device and a fan control method. BACKGROUND

[0002] The server power supply module (PSU) is an important component of the server, mainly responsible for providing stable power support for the server. When the PSU fails, the system reports fault information, and then the on-site staff carries out maintenance or replacement. In this process, the PSU cannot continue to supply power to the server, and the server suspends operation.

[0003] The existing technology of PSU design generally focuses on providing power input for the server, but does not fully consider the monitoring and diagnosis of PSU failure. The existing fault monitoring means mainly monitors the working state of the PSU through some sensors (such as temperature sensors, voltage sensors, etc.). For example, the temperature sensor detects the temperature of the ring or the key heating element, and triggers the over-temperature protection when the temperature exceeds the set threshold; the voltage sensor collects output voltage data in real time, and triggers over-voltage or under-voltage protection when the voltage exceeds the set upper limit or lower limit.

[0004] The existing technology mainly relies on the passive response of the system after the failure occurs, that is, as soon as a failure occurs, the PSU will immediately shut down the output power, and cannot take more detailed measures according to the severity of the failure. This passive failure handling method cannot prevent or adjust in time before the failure occurs, which may have a great impact on the operation of the server business, so when the PSU fails, the system cannot take measures in time to reduce the impact of the failure on the operation of the server business. This directly affects the normal operation of the server, and may even cause business interruption, thereby causing great economic losses. SUMMARY

[0051] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0052] In one embodiment, as shown in Figure 1 A device power supply is provided, comprising:

[0053] The device power supply comprises a power input, a power output, a first fan, a power controller, a first air pressure detection sensor, a second air pressure detection sensor, and a first temperature sensor. The first air pressure detection sensor, the second air pressure detection sensor, and the first temperature sensor are connected to the power controller.

[0054] The power input receives external power supply and converts it to supply power to the electronic device through the power output. The first air pressure detection sensor collects the first air pressure information of the power fan and transmits it to the power controller. The second air pressure detection sensor collects the second air pressure information of the airflow through the device power supply formed by the second fan in the electronic device and transmits it to the power controller. The first temperature sensor detects the first temperature information inside the device power supply and transmits it to the power controller. The power controller acquires one or more of the first air pressure information, the second air pressure information, and the first temperature information, and determines a first control strategy to control the rotating speed of the first fan according to one or more of the first air pressure information, the second air pressure information, and the first temperature information.

[0055] The air pressure detection sensor is a device used to measure the change of air pressure in an airflow or wind speed system. It is commonly used to monitor the pressure of air flow and assess the airflow status in the system. The temperature detection sensor is a device used to measure the temperature of an object or environment. It senses and converts temperature changes into readable electrical or mechanical signals.

[0056] Specifically, the external power supply is received through the power input end and converted to supply power to the external electronic device through the power output end, the first wind pressure information of the power fan collected by the first wind pressure detection sensor is transmitted to the power controller, the second wind pressure information of the airflow formed by the second fan in the electronic device and flowing through the device power supply is collected by the second wind pressure detection sensor and transmitted to the power controller, the first temperature information in the device power supply detected by the first temperature sensor is transmitted to the power controller, and the power controller determines the first control strategy to control the rotating speed of the first fan according to one or more of the first wind pressure information, the second wind pressure information and the first temperature information.

[0057] The device power supply receives the external power supply through the power input end and converts to supply power to the electronic device through the power output end, the first wind pressure information of the first fan in the power supply device is collected by the first wind pressure detection sensor, the second wind pressure information of the second fan in the airflow formed by the second fan and flowing through the device power supply is collected by the second wind pressure detection sensor, and the above wind pressure information is reported to the power controller, so that the power controller can comprehensively evaluate the fan performance and air flow state, and timely adjust the rotating speed of the fan, thereby optimizing the heat dissipation and operating environment of the electronic device, avoiding excessive wind pressure causing the fan to bear too much load, or low wind pressure causing insufficient heat dissipation. The power controller can generate a first control strategy according to the collected first wind pressure information, second wind pressure information and first temperature information through real-time monitoring and analysis of the first wind pressure information, second wind pressure information and first temperature information, so that the power controller can adjust the rotating speed of the fan at the most appropriate time. Reasonable fan speed regulation not only improves heat dissipation efficiency and avoids over-temperature protection of the power supply device, but also reduces the operating pressure of the fan and reduces mechanical wear, thereby prolonging the service life of the fan and the device power supply.

[0058] In one embodiment, the device power supply further comprises a circuit board and at least one strain detection sensor disposed on the circuit board for detecting strain information generated by the deformation of the circuit board under stress and transmitting the strain information to the power controller, and the power controller controls the rotating speed of the first fan according to the strain information.

[0059] The strain detection sensor is a device for measuring the strain, i.e. deformation, of the surface of an object or the inside of a material caused by external force. Strain is the degree of deformation of an object under external force, usually manifested as changes in length, width or thickness. The strain sensor converts this physical deformation into an electrical signal for measurement and analysis.

[0060] Specifically, the circuit board is provided with components such as common mode inductors or transformers. The strain detection sensor detects the strain information generated by the stress deformation of the circuit board due to the components on the circuit board. And report the strain information to the power controller. Through the real-time feedback of the strain information, the power controller can make more intelligent decisions. The controller can not only adjust the fan speed according to the wind pressure and temperature information, but also can comprehensively judge the stress condition of the circuit board combined with the strain information. In this way, it can more accurately respond to different working scenes or sudden conditions, and improve the adaptability and running stability of the equipment in variable environments.

[0061] In one embodiment, the device power supply further comprises a vibration detection sensor for detecting vibration information of the device power supply and transmitting the vibration information to the power controller, and the power controller controls the rotation speed of the first fan according to the vibration information.

[0062] The vibration detection sensor is a device used to detect and measure the vibration of objects or equipment. It can sense the vibration of objects or structures caused by external forces, mechanical operations, movements or other factors, and convert the vibration data into electrical signals for further analysis and processing.

[0063] Specifically, the vibration detection sensor can detect the vibration information of the power supply equipment in real time and transmit the data to the power controller. This allows the device to promptly understand whether abnormal vibration occurs during operation, such as vibration caused by equipment aging, mechanical failure, excessive load or external environmental changes. This real-time feedback helps prevent damage or failure of the device due to excessive vibration. When the power supply equipment has abnormal vibration, the vibration sensor can immediately detect the change and transmit the information to the power controller. The controller intelligently analyzes the vibration information, and the controller can take appropriate measures such as adjusting the fan speed or starting the alarm mechanism. This helps to discover device problems in advance and avoid structural damage or operational failure caused by excessive vibration of the device, thereby improving the safety of the device.

[0064] In one embodiment, as shown in Figure 2 A fan control method is provided, applied to a device power supply for powering electronic devices, the method comprising:

[0065] Step 202: Collecting first wind pressure information of the power fan through the first wind pressure detection sensor and transmitting the first wind pressure information to the power controller.

[0066] Specifically, the first fan's wind pressure information is collected by the first wind pressure detection sensor and transmitted to the power supply controller. The real-time feedback of the first wind pressure information provides the system with intelligent adaptive adjustment and accurate airflow data. The power supply controller can quickly identify and respond to potential faults based on the data from the wind pressure sensor.

[0067] Step 204: The second fan's wind pressure information, which forms the airflow through the device's power supply, is collected by the second wind pressure detection sensor and transmitted to the power supply controller.

[0068] Specifically, the second fan's wind pressure information, which forms the airflow through the device's power supply, is collected by the second wind pressure detection sensor and transmitted to the power supply controller. The real-time feedback of the second wind pressure information provides the system with intelligent adaptive adjustment and accurate airflow data. The power supply controller can quickly identify and respond to potential faults based on the data from the wind pressure sensor.

[0069] Step 206: The first temperature information inside the device's power supply is detected by the first temperature detection sensor and transmitted to the power supply controller.

[0070] Specifically, the first temperature detection sensor can monitor the temperature changes inside the power supply device in real time, and the power supply controller can dynamically adjust the device's cooling system based on these temperature data.

[0071] Step 208: The power supply controller obtains one or more of the first wind pressure information, second wind pressure information, and first temperature information, and determines a first control strategy based on one or more of the first wind pressure information, second wind pressure information, and first temperature information.

[0072] Specifically, obtaining multiple sensor information such as wind pressure and temperature enables the power supply controller to more comprehensively assess the device's operating state. Combined with wind pressure and temperature information, the power supply controller can make more accurate adjustments under different environmental and load conditions. For example, when the temperature is too high or the wind pressure is insufficient, the controller can accordingly increase the fan speed or start other cooling measures to keep the device in the best working state.

[0073] Step 210: The speed of the first fan is controlled according to the first control strategy.

[0074] Specifically, the controller adjusts the speed of the first fan according to the first control strategy, so that the first fan reaches the expected speed.

[0075] Specifically, the power controller monitors the first and second wind pressure information in real-time through the first and second wind pressure detection sensors, and monitors the temperature changes within the device through the first temperature detection sensor. Based on the data input from multiple sensors, the power controller can integrate wind pressure and temperature information and intelligently determine fan speed. According to environmental changes or load changes, the controller can automatically adjust the fan speed, ensuring heat dissipation effect and avoiding unnecessary energy consumption. This adaptive adjustment ensures efficient operation of the device under different working conditions.

[0076] This method optimizes the heat dissipation management and energy efficiency of the device by integrating the feedback information of multiple sensors, wind pressure, temperature and intelligent control strategy, and improves the stability, reliability, safety and operating efficiency of the device. The power controller dynamically adjusts the fan speed based on real-time data to ensure that the device is always in the best working condition, thereby effectively preventing faults and prolonging the service life of the device.

[0077] In one embodiment, the first control strategy is determined based on one or more of the first wind pressure information, the second wind pressure information, and the first temperature information, including:

[0078] According to the comparison between the first temperature information and the temperature threshold, a first risk threshold is determined;

[0079] In response to the first wind pressure information exceeding the first risk threshold and the second wind pressure information not exceeding the first risk threshold, the first control strategy is to reduce the first fan speed;

[0080] In response to the first wind pressure information not exceeding the first risk threshold and the second wind pressure information exceeding the first risk threshold, the first control strategy is to reduce the second fan speed of the electronic device and increase the first fan speed;

[0081] In response to the first wind pressure information and the second wind pressure information exceeding the first risk threshold, the first control strategy is to reduce the speed of the first fan and the second fan of the electronic device.

[0082] Specifically, by determining the first risk threshold based on the first temperature information and the temperature threshold, and comparing the first risk threshold with the first and second wind pressure information to obtain the first control strategy, the power controller adjusts the first fan speed according to the first control strategy. If the first wind pressure information exceeds the risk threshold and the second wind pressure information does not reach the risk threshold, the controller reduces the first fan speed. If the first wind pressure information does not exceed the first risk threshold and the second wind pressure information exceeds the first risk threshold, the controller reduces the second fan speed and increases the first fan speed. If the first and second wind pressure information exceed the first risk threshold, the controller reduces the speed of the first and second fans. If the first and second wind pressure information do not exceed the first risk threshold, the controller does not perform control operations. This reduces energy waste and ensures balanced equipment cooling. This flexible control mechanism improves system response efficiency and ensures that the equipment always operates in the best cooling state. The power controller can automatically adjust the fan speed under different working environments and load changes. Through accurate monitoring of wind pressure and temperature, this method can identify potential problems in the equipment cooling system in advance. Real-time response to the temperature and cooling needs of the equipment ensures that the equipment power supply is always in the best working state under different loads, environments, and working conditions.

[0083] In one embodiment, comprising:

[0084] Detecting vibration information of the equipment power supply through the vibration detection sensor and transmitting the vibration information to the power controller;

[0085] In response to the vibration detection sensor data exceeding the vibration threshold, the power controller reduces the first fan speed.

[0086] Specifically, the vibration detection sensor monitors the vibration information and reduces the fan speed when the vibration information exceeds the set vibration threshold, which effectively reduces the impact of vibration on the equipment. It can improve the stability of the equipment, prolong the service life, reduce noise, and optimize energy consumption. By actively controlling vibration and fan speed, the system not only ensures the safe operation of the equipment, but also improves the work efficiency and user experience of the equipment. This intelligent dynamic adjustment method ensures that the equipment can always operate efficiently and reliably in complex working environments.

[0087] In one embodiment, comprising:

[0088] Detecting strain information generated by the force deformation of the circuit board through the strain sensor and transmitting the strain information to the power controller;

[0089] In response to the strain sensor data exceeding the strain threshold, the power controller reduces the first fan speed and sends alarm information to the end user.

[0090] Specifically, the strain sensor detection circuit board detects the stress condition, monitors the strain information in real time, and automatically reduces the fan speed and sends alarm information to the user when the strain threshold is exceeded, effectively improving the safety, stability and adaptive ability of the equipment. Through this intelligent control, the equipment not only can prevent potential failure, but also can reduce energy consumption, prolong service life, and provide timely warning for users to ensure long-term stable operation of the equipment.

The power supply controller determines a second control strategy according to one or more of the first wind pressure information, the second wind pressure information, the third wind pressure information, the first temperature information, and the second temperature information to control the rotation speed of the second fan.

The power supply controller can generate a second control strategy according to the collected third wind pressure information and second temperature information through real-time monitoring and analysis of the third wind pressure information and the second temperature information, so that the power supply controller can adjust the rotation speed of the fan at the most appropriate time.

[0096] In step 302, the third wind pressure detection sensor detects the third wind pressure information of the second fan and transmits the third wind pressure information to the power supply controller.

[0097] Specifically, the third wind pressure detection sensor collects the second fan's wind pressure information and transmits it to the power controller. The real-time feedback of the second wind pressure information provides accurate airflow data for the system's intelligent adaptive adjustment. The power controller can quickly identify and respond to potential faults based on the wind pressure sensor's data.

[0098] Step 304 detects the second temperature information within the electronic device through the second temperature detection sensor and transmits it to the power controller.

[0099] Specifically, the second temperature detection sensor can monitor the temperature changes within the electronic device in real-time, and the power controller dynamically adjusts the device's cooling system based on these temperature data.

[0100] Step 306 determines the second control strategy to control the second fan's speed based on one or more of the first wind pressure information, the second wind pressure information, the third wind pressure information, the first temperature information, and the second temperature information through the power controller.

[0101] Specifically, obtaining multiple sensor information such as wind pressure and temperature enables the power controller to more comprehensively assess the device's operating state. In combination with wind pressure and temperature information, the power controller can make more accurate adjustments according to different environmental and load conditions. For example, when the temperature is too high or the wind pressure is insufficient, the controller can accordingly increase the fan speed or start other cooling measures to maintain the device in an optimal working state.

[0102] Specifically, the power controller monitors the wind pressure information in real-time through the third wind pressure detection sensor, and monitors the temperature changes within the electronic device through the second temperature detection sensor. Based on the data input from multiple sensors, the power controller can integrate wind pressure and temperature information and intelligently determine the fan speed. According to environmental changes or load changes, the controller can automatically adjust the fan speed, ensuring cooling effectiveness while avoiding unnecessary energy consumption. This adaptive adjustment ensures efficient operation of the device under different working conditions.

[0103] This method optimizes the device's cooling management and energy efficiency by integrating feedback information from multiple sensors, wind pressure, temperature, and intelligent control strategies, improving the device's stability, reliability, safety, and operating efficiency. The power controller dynamically adjusts the fan speed based on real-time data to ensure the device is always in an optimal working state, effectively preventing faults and prolonging the device's service life.

[0112] in response to the second wind pressure information exceeding the first risk threshold, the first wind pressure information not exceeding the first risk threshold, and the third wind pressure information not exceeding the second risk threshold, the second control strategy being to reduce the speeds of the first fan and the second fan;

[0114] If the third wind pressure information exceeds the second risk threshold, and the first and second wind pressure information do not exceed the first risk threshold, the controller reduces the second fan speed; if the first wind pressure information exceeds the first risk threshold, the second wind pressure information does not exceed the first risk threshold, and the third wind pressure information does not exceed the second risk threshold, the controller reduces the first fan speed; if the first and second wind pressure information exceed the risk threshold, and the third wind pressure information exceeds the second risk threshold, the controller reduces the speed of the first and second fans. If the third wind pressure information exceeds the second risk threshold, the second wind pressure information exceeds the first risk threshold, and the first wind pressure information does not exceed the first risk threshold, the controller reduces the second fan speed and increases the first fan speed; if the first wind pressure information exceeds the first risk threshold, the third wind pressure information exceeds the second risk threshold, and the second wind pressure information does not exceed the first risk threshold, the controller reduces the speed of the second and first fans; if the second wind pressure information exceeds the first risk threshold, the first wind pressure information does not exceed the first risk threshold, and the third wind pressure information does not exceed the second risk threshold, the controller reduces the speed of the first and second fans. If the first and second wind pressure information do not exceed the first risk threshold, and the third wind pressure information does not exceed the second risk threshold, the controller does not perform control operations at this time; to reduce energy waste and ensure balanced equipment cooling. This flexible control mechanism improves system response efficiency and ensures that the equipment is always running in the best cooling state. The power controller can automatically adjust the fan speed under different working environments and load changes. Through accurate monitoring of wind pressure and temperature, this method can identify potential problems in the equipment cooling system in advance. Real-time response to the temperature and cooling needs of the equipment ensures that the equipment power supply is always in the best working condition under different loads, environments, and working conditions.

[0115] In one of the embodiments, the electronic device further comprises an electronic device controller for controlling the second fan speed, and is in communication connection with the power controller, and the device power supply further comprises an internal controller for controlling the first fan speed, and is in communication connection with the power controller.

[0116] In one embodiment, the controller calculates a preset fan speed value according to the comparison result, including:

[0117] The controller obtains the speed, proportional variable, historical average speed, and integral variable of the first fan;

[0118] The power controller calculates the preset first fan speed value according to the control algorithm to obtain the preset first fan speed value, and the calculation formula is as follows:

[0119]

[0120] Wherein, the Sum is the first target rotating speed, A is the current rotating speed of the first fan, P is a proportional constant, which is obtained based on experience adjustment, I is an integral constant, which is obtained based on experience adjustment, is the cumulative error, which represents the cumulative sum of error values between the target rotating speed B and the current rotating speed A. By integrating these errors, the I term calculates a cumulative error value, so as to adjust the rotating speed of the fan to eliminate long-term existing deviation.

[0121] Specifically, the following parameters and data are set: the target rotating speed B is 2000 RPM (rotations per minute), the current rotating speed A is 1800 RPM, the proportional constant P is 0.8, the integral constant I is 0.2, and the historical cumulative error is 0 RPM;

[0122] The error between the target rotating speed and the current rotating speed is calculated: error = B-A = 2000-1800 = 200 RPM;

[0123] Assuming that the integral error is currently zero, the new integral error can be obtained by accumulating the current error: cumulative error = historical cumulative error + current error = 0+200 = 200 RPM;

[0124] The preset first fan rotating speed value = A+P x error + I x cumulative error, and the specific numerical value is: preset first fan rotating speed value = 1800+0.8x200+0.2x200;

[0125] According to the calculation result, the preset first fan rotating speed value is 2000 RPM. It should be understood that the second fan preset rotating speed value is the same as the above method, and therefore is not described here.
