Description

Technical Field

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

[0002] As an important component of the server, the server power supply unit (PSU) is mainly responsible for providing stable power support for the server. When the PSU fails, the system reports the fault information, and then the on-site staff will repair or replace it. During this process, the PSU can no longer supply power to the server, and the server stops running.

[0003] The PSU design of the existing technology generally focuses on providing power input for the server, but has not been fully considered in terms of monitoring and diagnosis of PSU failures. Existing fault monitoring methods mainly monitor the working status of the PSU through some sensors (such as temperature sensors, voltage sensors, etc.). For example, the temperature sensor detects the ambient temperature or the temperature of key heating components, and triggers 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 or lower limit.

[0004] The existing technology mainly relies on the passive response of the system after a fault occurs, that is, once a fault occurs, the PSU will immediately shut down the output power, and it is impossible to take more detailed countermeasures according to the severity of the fault. This passive fault handling method cannot prevent or adjust the fault in time before it occurs, which may have a great impact on the operation of the server business. Therefore, when the PSU fails, the system cannot take timely measures to reduce the impact of the fault on the operation of the server business. This directly affects the normal operation of the server and may even cause business interruption, resulting in great economic losses. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In one embodiment, Figure 1 As shown, a device power supply is provided, comprising:

[0053] The device power supply includes a power input terminal, a power output terminal, a first fan, a power controller, a first wind pressure detection sensor, a second wind pressure detection sensor, and a first temperature sensor, wherein the first wind pressure detection sensor, the second wind pressure detection sensor, and the first temperature detection sensor are connected to the power controller;

[0054] Among them, the power input end receives external power supply and powers the electronic device through the power output end after conversion, the first wind pressure detection sensor is used to collect first wind pressure information of the power supply fan and transmit the first wind pressure information to the power supply controller, the second wind pressure detection sensor is used to collect second wind pressure information of the airflow formed by the second fan in the electronic device flowing through the device power supply and transmit the second wind pressure information to the power supply controller, the first temperature sensor is used to detect first temperature information in the device power supply and transmit the first temperature information to the power supply controller, the power supply controller is used to obtain one or more of the first wind pressure information, the second wind pressure information and the first temperature information, and determine a first control strategy to control the rotation speed of the first fan based on one or more of the first wind pressure information, the second wind pressure information and the first temperature information.

[0055] Among them, the wind pressure detection sensor is a device used to measure the change of air pressure in the airflow or wind speed system. It is usually used to monitor the pressure of air flow and then evaluate 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, external power is received through the power input terminal and powered for external electronic devices through the power output terminal after conversion, the first wind pressure detection sensor transmits the collected first wind pressure information of the power supply fan to the power controller, the second wind pressure detection sensor collects the second wind pressure information of the airflow flowing through the device power supply formed by the second fan in the electronic device and transmits it 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 a first control strategy to control the rotation speed of the first fan based on one or more of the acquired first wind pressure information, the second wind pressure information and the first temperature information.

[0057] The above-mentioned device power supply receives external power supply through the power input end and powers the electronic device through the power output end after conversion, collects the first wind pressure information of the first fan in the power supply device through the first wind pressure detection sensor, collects the second wind pressure information of the second fan in the airflow formed by the second fan in the electronic device flowing through the device power supply through the second wind pressure detection sensor, and reports the above wind pressure information to the power supply controller, so that the power supply controller can comprehensively evaluate the fan performance and air flow state, and adjust the fan speed in time, so as to optimize the heat dissipation and operating environment of the electronic device, avoid excessive wind pressure causing excessive burden on the fan, or insufficient heat dissipation due to low wind pressure. The power supply controller can generate a first control strategy based on the collected, through real-time monitoring and analysis of the first wind pressure information, the second wind pressure information and the first temperature information, so that the power supply controller can adjust the fan speed at the most appropriate time. Reasonable fan speed adjustment can not only improve the heat dissipation efficiency and avoid over-temperature protection of the power supply device, but also reduce the operating pressure of the fan and reduce mechanical wear, thereby extending the service life of the fan and the device power supply.

[0058] In one embodiment, the device power supply also includes a circuit board and at least one strain detection sensor. The at least one strain detection sensor is arranged on the circuit board to detect strain information generated by the deformation of the circuit board under force and transmit the strain information to the power supply controller. The power supply controller controls the rotation speed of the first fan according to the strain information.

[0059] Among them, the strain detection sensor is a device used to measure the strain or deformation caused by external forces on the surface of an object or inside a material. Strain is the degree of deformation of an object under the action of external forces, usually manifested as a change in length, width or thickness. The strain sensor converts this physical deformation into an electrical signal for measurement and analysis.

[0060] Specifically, components such as common-mode inductors or transformers are provided on the circuit board. The strain information generated by the pressure exerted on the circuit board by the components on the circuit board, which causes the deformation of the circuit board, is detected by the strain detection sensor. The strain information is reported to the power controller. With the real-time feedback of the strain information, the power controller can make smarter decisions. The controller can not only adjust the fan speed according to the wind pressure and temperature information, but also make a comprehensive judgment on the stress condition of the circuit board based on the strain information. In this way, it can respond more accurately to different working scenarios or emergencies, and improve the adaptability and operating stability of the equipment in a changing environment.

[0061] In one embodiment, the device power supply further includes a vibration detection sensor, which is used to detect vibration information of the device power supply and transmit the vibration information to the power supply controller, and the power supply controller controls the rotation speed of the first fan according to the vibration information.

[0062] Among them, the vibration detection sensor is a device used to detect and measure the vibration of an object or device. It can sense the vibration of an object or structure caused by external forces, mechanical operations, movement 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 device in real time and transmit the data to the power supply controller. This enables the device to promptly understand whether abnormal vibration occurs during its operation, such as vibration caused by equipment aging, mechanical failure, overload or changes in the external environment. This real-time feedback helps prevent damage or failure of the equipment due to excessive vibration. When the power supply device vibrates abnormally, the vibration sensor can immediately detect the change and transmit the information to the power supply controller. The controller performs intelligent analysis based on the vibration information, and the controller can take corresponding measures, such as adjusting the fan speed or activating the alarm mechanism. This helps to detect equipment problems in advance and avoid structural damage or operational failures caused by excessive vibration of the equipment, thereby improving the safety of the equipment.

[0064] In one embodiment, Figure 2 As shown, a fan control method is provided, which is applied to a device power supply, wherein the device power supply is used to power an electronic device, and the method comprises:

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

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

[0067] Step 204: collect second wind pressure information of the airflow formed by the second fan in the electronic device and flowing through the power supply of the device through the second wind pressure detection sensor, and transmit the second wind pressure information to the power supply controller.

[0068] Specifically, the wind pressure information of the second fan in the electronic device flowing through the power supply of the device is collected through 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 provides accurate airflow data. The power supply controller can quickly identify and respond to potential faults based on the data of the wind pressure sensor.

[0069] Step 206: Detect first temperature information in the device power supply by using a first temperature detection sensor and transmit the first temperature information to a power supply controller.

[0070] Specifically, the first temperature detection sensor can monitor the temperature changes in the power supply device in real time, and the power supply controller dynamically adjusts the heat dissipation system of the device based on these temperature data.

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

[0072] Specifically, obtaining multiple sensor information such as wind pressure and temperature enables the power controller to more comprehensively evaluate the operating status of the device. Combined with wind pressure and temperature information, the power controller can make more precise adjustments based on different environmental and load conditions. For example, when the temperature is too high or the wind pressure is insufficient, the controller can increase the fan speed or initiate other cooling measures accordingly to keep the device in optimal working condition.

[0073] Step 210: Control the rotation speed of the first fan according to the first control strategy.

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

[0075] Specifically, the power controller monitors the first wind pressure information and the second wind pressure information in real time through the first wind pressure detection sensor and the second wind pressure detection sensor. The power controller monitors the temperature change in the device through the first temperature detection sensor. Based on the data input of multiple sensors, the power controller can integrate the 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 to ensure the heat dissipation effect and avoid unnecessary energy consumption. This adaptive adjustment ensures the efficient operation of the device under different working conditions.

[0076] This method optimizes the equipment's heat dissipation management and energy efficiency by integrating feedback information from multiple sensors, such as wind pressure, temperature, and intelligent control strategies, and improves the equipment's stability, reliability, safety, and operating efficiency. The power controller dynamically adjusts the fan speed based on real-time data to ensure that the equipment is always in the best working state, thereby effectively preventing failures and extending the equipment's service life.

[0077] In one embodiment, determining a first control strategy according to one or more of the first wind pressure information, the second wind pressure information, and the first temperature information includes:

[0078] Determining a first risk threshold based on a comparison between the first temperature information and a temperature threshold;

[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 speed of the first fan;

[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 rotation speeds of the first fan and the second fan of the electronic device.

[0082] Specifically, the first risk threshold is determined by comparing the first temperature information with the temperature threshold, and the first control strategy is obtained by comparing the first risk threshold with the first wind pressure information and the second wind pressure information. The power controller adjusts the speed of the first fan 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 speed of the first fan. 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 speed of the second fan and increases the speed of the first fan. If the first wind pressure information and the second wind pressure information exceed the first risk threshold, the controller reduces the speed of the first fan and the second fan. If the first wind pressure information and the second wind pressure information do not exceed the first risk threshold, the controller does not perform a control operation. To reduce energy waste and ensure the heat dissipation balance of the device. This flexible control mechanism improves the system response efficiency and ensures that the device always operates in the best heat dissipation state. The power controller can automatically adjust the fan speed under different working environments and load changes. By accurately monitoring wind pressure and temperature, the method can identify potential problems in the device heat dissipation system in advance. Respond to the temperature and heat dissipation requirements of the device in real time to ensure that the device power supply is always in the best working state under different loads, environments and working conditions.

[0083] In one embodiment, it includes:

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

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

[0086] Specifically, this method effectively reduces the impact of vibration on the device by monitoring vibration information through a vibration detection sensor and reducing the fan speed when the vibration information exceeds the set vibration threshold. It can improve the stability of the device, extend its 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 device, but also improves the device's work efficiency and user experience. This intelligent dynamic adjustment method ensures that the device can always operate efficiently and reliably in a complex working environment.

[0087] In one embodiment, it includes:

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

[0089] In response to the strain sensor data exceeding a strain threshold, the power controller reduces the speed of the first fan and sends an alarm message to a terminal user.

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

The power controller can generate a second control strategy based on the collected, through real-time monitoring and analysis of the third wind pressure information and the second temperature information, so that the power controller can adjust the fan speed at the most appropriate time. Reasonable fan speed adjustment can not only improve the heat dissipation efficiency and avoid over-temperature protection of the power supply equipment, but also reduce the operating pressure of the fan and reduce mechanical wear, thereby extending the service life of the fan and the device power supply.

[0098] In step 304, second temperature information in the electronic device is detected by a second temperature detection sensor and transmitted to the power controller.

[0099] Specifically, the second temperature detection sensor can monitor the temperature changes in the electronic device in real time, and the power controller dynamically adjusts the heat dissipation system of the device based on these temperature data.

[0100] In step 306, the power controller determines a second control strategy to control the rotation speed of the second fan 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.

[0101] Specifically, obtaining multiple sensor information such as wind pressure and temperature enables the power controller to more comprehensively evaluate the operating status of the device. Combined with wind pressure and temperature information, the power controller can make more precise adjustments based on different environmental and load conditions. For example, when the temperature is too high or the wind pressure is insufficient, the controller can increase the fan speed or initiate other cooling measures accordingly to keep the device in optimal working condition.

[0102] Specifically, the power controller monitors the wind pressure information in real time through the third wind pressure detection sensor, and monitors the temperature change in the electronic device through the second temperature detection sensor. Based on the data input of multiple sensors, the power controller can integrate the 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 to ensure the heat dissipation effect and avoid unnecessary energy consumption. This adaptive adjustment ensures the efficient operation of the device under different working conditions.

[0103] This method optimizes the equipment's heat dissipation management and energy efficiency by integrating feedback information from multiple sensors, such as wind pressure, temperature, and intelligent control strategies, and improves the equipment's stability, reliability, safety, and operating efficiency. The power controller dynamically adjusts the fan speed based on real-time data to ensure that the equipment is always in the best working state, thereby effectively preventing failures and extending the equipment's service life.

[0113] Specifically, the first risk threshold is determined by comparing the first temperature information with the temperature threshold, and the second risk threshold is determined by comparing the second temperature information with the temperature threshold; the second control strategy is obtained by comparing the second risk threshold with the third wind pressure information, and the power controller adjusts the speed of the first fan and the second fan according to the second control strategy.

[0114] If the third wind pressure information exceeds the second risk threshold, and the first wind pressure information and the second wind pressure information do not exceed the first risk threshold, the controller reduces the speed of the second fan; 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 speed of the first fan; if the first wind pressure information and the 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 fan and the second fan. 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 speed of the second fan and increases the speed of the first fan; 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 fan and the first fan; 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 fan and the second fan. If the first wind pressure information and the 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 the heat dissipation balance of the equipment. This flexible control mechanism improves the system response efficiency and ensures that the equipment always operates in the best heat dissipation state. The power controller can automatically adjust the fan speed under different working environments and load changes. Through precise monitoring of wind pressure and temperature, this method can identify potential problems in the equipment cooling system in advance. Respond to the temperature and heat dissipation requirements of the equipment in real time to ensure that the equipment power supply is always in the best working state under different loads, environments and working conditions.

[0115] In one embodiment, the electronic device further includes an electronic device controller, which is used to control the speed of the second fan and is communicatively connected to the power supply controller. The device power supply also includes an internal controller, which is used to control the speed of the first fan and is communicatively connected to the power supply controller.

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

[0117] The controller obtains the rotation speed, proportional variable, historical average rotation 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, Sum is the first target speed, A is the current speed of the first fan, P is a proportional constant obtained by empirical adjustment, and I is an integral constant obtained by empirical adjustment. is the error accumulation, which represents the cumulative sum of the error values ​​between the target speed B and the current speed A. By integrating these errors, the I term calculates a cumulative error value, thereby adjusting the fan speed to eliminate the long-term deviation.

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

[0122] Calculate the error between the target speed and the current speed: Error = BA = 2000-1800 = 200RPM;

[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 speed value = A + P × error + I × cumulative error, substitute the specific value: the preset first fan speed value = 1800 + 0.8 × 200 + 0.2 × 200;

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