[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 17, 2024, with application number 202410065333.6, entitled “A Server Noise Reduction Method, System, Device, Equipment and Computer Medium,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of computers, and in particular, to a server noise reduction method, system, device, equipment, and computer non-volatile readable storage medium. Background Art

[0004] With the advancement of technology, servers are becoming increasingly versatile and power-hungry. This requires servers to support more CPUs (Central Processing Units), network cards, memory, and GPUs (Graphics Processing Units), placing higher demands on server heat dissipation. For air-cooled servers, increasing the number of fans and speed remains a solution, but this inevitably leads to increased ambient noise.

[0005] To reduce server noise, water cooling, large fan installation, and other methods can be used to avoid or minimize noise. Alternatively, a separate computer room, high-noise lab, or dedicated silent server cabinet can be set up to mitigate the noise's external impact. However, water cooling and large fan installation only improve fan noise, with limited effectiveness, and they also take up significant internal server space. Setting up a separate computer room, high-noise lab, or dedicated silent server cabinet not only requires ensuring adequate ventilation for the servers, but also creates high costs and poor applicability for noise reduction measures.

[0006] In summary, how to conveniently and accurately reduce the noise of a server is a problem that currently needs to be solved urgently by those skilled in the art.

[0091] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0092] Please refer to FIG1 , which is a first flow chart of a server noise reduction method provided in an embodiment of the present application.

[0093] An embodiment of the present application provides a server noise reduction method, which is applied to a server and may include the following steps:

[0094] Step S101: Determine the server type information of the server.

[0095] In actual applications, the server may first determine its own type information, that is, may first determine its own server type information. The server type information may include a voice server or a non-voice server.

[0096] Step S102: Send the server type information to the noise reduction device, so that when the server type information is a voice server, the noise reduction device performs noise reduction on the server according to the ring noise cancellation method, or when the server type information is a non-voice server, the noise reduction device performs noise reduction on the server according to the active noise control method; wherein the noise reduction device is connected to the server via hot plugging.

[0097] In actual applications, after determining its own server type information, the server may send the server type information to the noise reduction device, so that the noise reduction device can perform noise reduction on the server in a targeted manner according to the server type information.

[0098] In actual application scenarios, after receiving the server type information, the noise reduction device can perform noise reduction on the server according to the Environmental Noise Cancellation (ENC) method when the server type information is a voice server, and according to the Active Noise Control (ANC) method when the server type information is a non-voice server.

[0099] It should be noted that the noise reduction device in this application is connected to the server via a hot-swap connection, enabling plug-and-play operation. This allows the device to be removed or replaced in the event of a failure without affecting the normal operation of the server. The hot-swap feature in this application includes both power hot-swap and signal hot-swap. When the noise reduction device is physically connected to the server via an interface, the hardware layer of the connected system uses a MOS (Metal Oxide Semiconductor Field Effect Transistor) on-off method to control transient surge current on the power bus to a relatively low level, completing the electrical connection and enabling power hot-swap. The purpose of signal hot-swap is to properly isolate the signal line from the server control center and terminate all communications before the module is powered off. When the server power module does not incorporate a signal hot-swap design, transient voltages generated on the signal line may cause server communication anomalies. With the signal hot-swap design, transient voltages are limited to a reasonable level, and the server control center is notified in advance to terminate communication tasks, achieving signal hot-swap.

[0100] The present application provides a server noise reduction method, which is applied to a server to determine the server type information of the server; and sends the server type information to a noise reduction device, so that the noise reduction device performs noise reduction on the server according to a ring noise cancellation method when the server type information indicates a voice server, or according to an active noise control method when the server type information indicates a non-voice server; wherein the noise reduction device is connected to the server via a hot-swappable method. The beneficial effect of the present application is that after the server sends its own server type information to the noise reduction device, the noise reduction device performs noise reduction on the server according to the ring noise cancellation method when the server type information indicates a voice server, and according to the active noise control method when the server type information indicates a non-voice server, thereby achieving flexible selection of a noise reduction method suitable for the server for noise reduction and good noise reduction accuracy; and the noise reduction device and the server are connected via a hot-swappable method. In this way, when noise reduction is required for the server, only the noise reduction device needs to be connected to the server, and when noise reduction is not required, the noise reduction device can be separated from the server, allowing for quick noise reduction management of the server.

[0101] Please refer to FIG. 2 , which is a second flow chart of a server noise reduction method provided in an embodiment of the present application.

[0102] An embodiment of the present application provides a server noise reduction method, which is applied to a server and may include the following steps:

[0103] Step S201: Determine the server type information of the server.

[0104] Step S202: Send the server type information to the noise reduction device, so that when the server type information is a voice server, the noise reduction device performs noise reduction on the server according to the ring noise elimination method, or when the server type information is a non-voice server, the noise reduction device performs noise reduction on the server according to the active noise control method; wherein the noise reduction device is connected to the server via hot plugging.

[0105] Step S203: Obtain the user's access rights.

[0106] Step S204: Acquire device information of the noise reduction device to which access permission is allowed.

[0107] Step S205: sending the device information to the network interface of the baseboard management controller via the baseboard management controller of the server, so that the user can view the device information via the network interface.

[0108] In actual applications, when using noise reduction equipment to reduce noise on a server, in order to facilitate users to understand the working information of the noise reduction equipment through the server, it is also possible to obtain the user's access rights; obtain the device information of the noise reduction equipment that is allowed to be accessed by the access rights; and send the device information to the network interface of the baseboard management controller (BMC) of the server through the baseboard management controller (BMC), so that the user can view the device information through the network interface. The access rights determine how much information about the noise reduction equipment the user can view. For example, a user with low access rights can only view the name and power consumption of the noise reduction equipment, while a user with high access rights can view the working mode and power switch options of the noise reduction equipment. In addition, the access rights can also be used to determine whether the user can operate the noise reduction equipment, etc. This application does not limit this.

[0109] It should be noted that the device information of the noise reduction device can be determined according to actual needs. For example, the device information of the noise reduction device may include the noise reduction mode, multiple microphone noise collection values, and the noise value after noise reduction.

[0110] In actual application scenarios, to facilitate user control of noise reduction devices through a server, the server sends device information to the network interface of the baseboard management controller via the server's baseboard management controller. The server can then receive a first control instruction transmitted via the network interface through the baseboard management controller. The first control instruction is then sent to the noise reduction device, causing the noise reduction device to perform operation control according to the first control instruction, thereby enabling the baseboard management controller of the application server to control the noise reduction device. The content of the first control instruction can be flexibly determined based on actual needs. For example, the first control instruction may include a mode control instruction for the noise reduction device, a power switch control instruction, and the like.

[0111] In actual application scenarios, before obtaining the user's access rights, the server can also perform security verification on the process of the user logging into the network interface, that is, obtaining a login request to log into the baseboard management controller's network interface; responding to the login request, displaying the network interface; obtaining the login information entered by the user on the network interface; verifying the login information, and if the verification passes, executing the steps to obtain the user's access rights. It should be noted that when the baseboard management controller's network interface is on the server itself, the server can control the network interface login process, while when the baseboard management controller's network interface is on a device other than the server, the other device can control the network interface login process, in which case the server only needs to receive the corresponding information from the network interface through the baseboard management controller.

[0112] Please refer to FIG3 , which is a third flow chart of a server noise reduction method provided in an embodiment of the present application.

[0113] An embodiment of the present application provides a server noise reduction method, which is applied to a server and may include the following steps:

[0114] Step S301: Determine the server type information of the server.

[0115] Step S302: Send the server type information to the noise reduction device, so that when the server type information is a voice server, the noise reduction device performs noise reduction on the server according to the ring noise cancellation method, or when the server type information is a non-voice server, the noise reduction device performs noise reduction on the server according to the active noise control method; wherein the noise reduction device is connected to the server via hot plugging.

[0116] Step S303: Obtain the user's access rights.

[0117] Step S304: Acquire device information of the noise reduction device to which access permission is allowed.

[0118] Step S305: The device information is sent to a setting interface of the basic input and output system via the basic input and output system of the server, so that the user can view the device information via the setting interface.

[0119] In actual applications, in the process of applying noise reduction equipment to the server for noise reduction, in order to facilitate users to understand the working information of the noise reduction equipment through the server, the server can also obtain the user's access rights; obtain the device information of the noise reduction equipment that is allowed to be accessed by the access rights; and send the device information to the setting interface of the basic input and output system (BIOS) through the server, so that the user can view the device information through the setting interface, so that the user can view the device information of the noise reduction device through the setting interface of the basic input and output system.

[0120] It should be noted that the amount of data of the device information of the noise reduction device that can be viewed through the basic input and output system setting interface can be determined according to the size of the setting interface, and this application does not limit it here.

[0121] In actual application scenarios, to facilitate user control of the noise reduction device through the server, the server sends device information to the basic input and output system settings interface through the server's basic input and output system. The server can also receive a second control instruction transmitted from the settings interface through the basic input and output system; the second control instruction is sent to the noise reduction device so that the noise reduction device operates according to the second control instruction. The content of the second control instruction can refer to the first control instruction and is not repeated here.

[0122] Please refer to FIG4 , which is a fourth flow chart of a server noise reduction method provided in an embodiment of the present application.

[0123] An embodiment of the present application provides a server noise reduction method, which is applied to a server and may include the following steps:

[0124] Step S401: Determine the server type information of the server.

[0125] Step S402: Send the server type information to the noise reduction device, so that when the server type information is a voice server, the noise reduction device performs noise reduction on the server according to the ring noise elimination method, or when the server type information is a non-voice server, the noise reduction device performs noise reduction on the server according to the active noise control method; wherein the noise reduction device is connected to the server via hot plugging.

[0126] Step S403: Collect server performance information of the server.

[0127] Step S404: Send the server performance information to the noise reduction device, so that the noise reduction device performs noise prediction on the server based on the server performance information.

[0128] In actual applications, in order to facilitate the noise reduction device to accurately reduce the noise of the server, the server can also collect the server performance information of the server; send the server performance information to the noise reduction device, so that the noise reduction device can predict the noise of the server based on the server performance information, and then reduce the noise of the server according to the noise prediction results.

[0129] In actual application scenarios, during the process of collecting the server performance information, the server can collect the fan speed information of the server; collect the number value of the server's central processing unit and the first temperature value of each central processing unit; collect the second temperature value of the server's memory; collect the operating frequency value of the server's radiator; and use the fan speed information, number value, first temperature value, second temperature value and operating frequency value as server performance information.

[0130] Please refer to FIG5 , which is a fifth flow chart of a server noise reduction method provided in an embodiment of the present application.

[0131] A server noise reduction method provided in an embodiment of the present application, applied to a noise reduction device, may include the following steps:

[0132] Step S501: Obtain server type information sent by the server.

[0133] Step S502: In response to the server type information being a voice server, noise reduction is performed on the server according to an ambient noise cancellation method.

[0134] Step S503: In response to the server type information being a non-voice server, noise reduction is performed on the server according to an active noise control method; wherein the noise reduction device is connected to the server in a hot-swap manner.

[0135] The present application provides a server noise reduction method, which is applied to a noise reduction device and obtains server type information sent by a server; in response to the server type information being a voice server, the server is noise-reduced according to a ring noise elimination method; and in response to the server type information being a non-voice server, the server is noise-reduced according to an active noise control method; wherein the noise reduction device is connected to the server via a hot-swap method. The beneficial effect of the present application is that after the server sends its own server type information to the noise reduction device, the noise reduction device performs noise reduction on the server according to the ring noise elimination method when the server type information is a voice server, and performs noise reduction on the server according to the active noise control method when the server type information is a non-voice server, thereby achieving flexible selection of a noise reduction method suitable for the server for noise reduction and good noise reduction accuracy; and the noise reduction device and the server are connected via a hot-swap method. In this way, when noise reduction is required for the server, only the noise reduction device needs to be connected to the server, and when noise reduction is not required for the server, the noise reduction device can be separated from the server, allowing for quick noise reduction management of the server.

[0136] In practical applications, in order to accurately reduce the noise of the server, the noise reduction device can also obtain the server performance information sent by the server; perform data cleaning and selection on the server performance information to obtain target performance information; send the target performance information to a prediction model pre-trained based on the XGBoost (Extreme Gradient Boosting, an optimized distributed gradient boosting library) algorithm; and receive the server noise value output by the prediction model. During the training of the prediction model, the known noise value and corresponding known performance information of the server can be collected, and the prediction model can be trained using the known noise value and known performance information, and the corresponding loss value is calculated. The training of the prediction model ends when the loss value meets the set requirements. Otherwise, the prediction model is retrained using the known noise value and known performance information.

[0137] Please refer to FIG6 , which is a schematic structural diagram of a server noise reduction system provided in an embodiment of the present application.

[0140] The noise reduction device is configured to perform noise reduction on the server according to a ring noise cancellation method when the server type information is a voice server, or to perform noise reduction on the server according to an active noise control method when the server type information is a non-voice server.

In addition, the noise reduction device can also be equipped with an embedded display screen, which can dynamically display the predicted noise value, the actual noise value, the noise reduction value, and other related information such as the received server fan speed, so that the user can obtain better information feedback and better experience the noise reduction effect in terms of hearing and vision.

[0144] In actual applications, the server can also be set to: obtain the user's access rights; obtain the device information of the noise reduction device that is allowed to be accessed by the access rights; send the device information to the network interface of the baseboard management controller through the server's baseboard management controller, so that the user can view the device information through the network interface.

[0145] In actual applications, the server can also be configured to: send device information to the network interface of the baseboard management controller through the baseboard management controller of the server, and then receive the first control instruction transmitted from the network interface through the baseboard management controller; send the first control instruction to the noise reduction device, so that the noise reduction device performs work control according to the first control instruction.

[0146] In actual applications, the server can also be configured to: obtain a login request for logging into the network interface of the baseboard management controller before obtaining the user's access rights; respond to the login request and display the network interface; obtain the login information entered by the user in the network interface; verify the login information, and if the verification passes, execute the steps to obtain the user's access rights.

[0147] In actual applications, the server can also be configured to: obtain the user's access rights; obtain the device information of the noise reduction device that is allowed to be accessed by the access rights; and send the device information to the setting interface of the basic input and output system through the basic input and output system of the server, so that the user can view the device information through the setting interface.

[0148] In actual applications, the server can also be set to: after sending the device information to the setting interface of the basic input and output system through the basic input and output system of the server, receive the second control instruction transmitted from the setting interface through the basic input and output system; send the second control instruction to the noise reduction device, so that the noise reduction device can perform work control according to the second control instruction.

[0149] In practical applications, the server can also be configured to: collect server performance information; send the server performance information to the noise reduction device, so that the noise reduction device can predict the server noise based on the server performance information. Accordingly, the noise reduction device can also be configured to: obtain the server performance information sent by the server; clean and select the server performance information to obtain target performance information; send the target performance information to a prediction model pre-trained based on the XGBoost algorithm; and receive the server noise value output by the prediction model.

[0150] In actual applications, when collecting server performance information, the server can collect the server's fan speed information; collect the number value of the server's central processing unit and the first temperature value of each central processing unit; collect the second temperature value of the server's memory; collect the operating frequency value of the server's radiator; and use the fan speed information, number value, first temperature value, second temperature value and operating frequency value as server performance information.

[0151] In practical applications, noise reduction equipment can be combined with 3D open-field active noise reduction. This is because 3D open-field active noise reduction requires two or more pickup microphones. These microphones are configured to collect server noise signals and convert them into electrical signals, which are then transmitted via circuits to the control center of the noise reduction equipment. The equipment then processes the noise signals based on the currently selected noise reduction mode and an optimized algorithm for indoor 3D sound source localization.

[0152] For ease of understanding, assuming that the noise reduction device currently selects the active noise control noise reduction mode, the signal can be processed by the three-dimensional open sound field active noise control noise reduction processing unit, and the indoor three-dimensional sound source positioning optimization algorithm, adaptive filtering algorithm and LMS algorithm (Least Mean Square, minimum error mean square algorithm), and combined with the current noise reduction hardware equipment, such as the distance between the microphone and the speaker, the microphone sensitivity, etc., the reverse interference signal for noise reduction is calculated, and the calculated reverse interference signal is output with fidelity through the Hi-Fi (high-fidelity) speaker, emitting a sound wave with the same amplitude as the original noise of the server but opposite phase (also called anti-phase), and the anti-phase sound wave is superimposed on the server noise, thereby achieving the result of global noise reduction.

[0153] For ease of understanding, assuming that the noise reduction device currently selects the ring noise cancellation mode, the signal can be processed by the three-dimensional open sound field ring noise cancellation processing unit. In this process, in addition to the indoor three-dimensional sound source positioning optimization algorithm, adaptive filtering algorithm and LMS algorithm, it also relies on AI (Artificial Intelligence) neural network noise reduction algorithm, gain control, echo cancellation, and BeamForming technology algorithm in multi-microphone scenarios for processing. Before the environmental noise filtering module is calculated, in order to ensure the noise reduction effect, the gain of the microphone array and the delay of the microphone can be corrected first. Then, it is detected whether the data collected by the voice microphone is a voice segment. If it is a voice segment, the environmental noise is estimated based on the environmental noise collected by the reference microphone and the voice data of the voice microphone, and the corresponding noise suppression parameters are calculated. Finally, the filter module filters out the environmental noise; conversely, if there is no voice signal, no environmental noise filtering is performed. The corresponding reverse interference signal is calculated and then output through the Hi-Fi speaker with signal fidelity, emitting a sound wave with the same amplitude as the original sound but opposite phase (also called anti-phase). The anti-phase sound wave is superimposed on the noise, thereby achieving the result of global noise reduction.
