Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of switch heat dissipation, in particular to a heat dissipation regulation method and device, communication equipment and storage medium. BACKGROUND

[0002] White box switch is a flexible and efficient network device, and users can deploy different applications and services with personalized features on the hardware system according to needs. The white box switch has the function of decoupling software, can reduce cost, improve flexibility, build different components and modules for manufacturers' special needs, and is welcomed by many manufacturers and data centers, especially widely used in large data centers.

[0003] Consistent with other electronic devices, the white box switch also needs to ensure good heat dissipation conditions to maintain the normal operation of each device when working. If the device temperature is too high, it will often affect the normal use and operation of the white box switch. Generally speaking, the heat dissipation related devices in the white box switch mainly include heat dissipation fins, fans and temperature sensors. In order to ensure the heat dissipation effect under high temperature conditions, and at the same time save the energy consumption of the fan when it works at high speed, the fan speed needs to be adjusted according to the temperature sensor data of the white box switch to ensure that the fan speed can also be adjusted when the internal device temperature is too high to ensure the heat dissipation effect.

[0004] The current network operating system of the white box switch, such as the SONiC system (Software for Open Networking in the Cloud, open source network operating system), provides simple heat dissipation regulation software, which can set the fan speed to a certain fixed value according to the current temperature sensor value. For example, when the reading of a sensor of the white box switch exceeds a certain threshold, the fan is set to full speed operation, and below this threshold, it is set to a certain fixed speed non-full speed operation. However, this regulation software function can only provide a fixed speed regulation scheme with multiple grades, and does not have other complex functions related to heat dissipation protection, which cannot meet the more complex heat dissipation requirements of the white box switch.

[0065] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and based on various changes and modifications of the following embodiments. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present application, and the embodiments can be combined and referenced with each other without contradiction.

[0066] Referring to Figure 1 , a step flowchart of the heat dissipation regulation method provided by the embodiments of the present application is shown, and the method can include:

[0067] Step 101, acquiring temperature sensor information and fan information at a preset regulation time.

[0068] In the present embodiment, the overall structure of the heat dissipation regulation in the present embodiment follows the architecture of fan regulation of a network operating system, and the network operating system is generally a SONiC system, wherein the network operating system of the white box switch is an operating system for monitoring the operation of the switch, specifically monitoring the temperature, fan speed and the like of the switch, and has a series of network configuration functions and tools. The heat dissipation regulation software for controlling the fan state according to the state of each temperature sensor is configured in the network operating system, which can ensure that when the internal temperature of the switch rises, the fan speed is adjusted accordingly to dissipate heat, and under good heat dissipation conditions, the normal operation of each device is maintained to ensure that the switch is in a stable running state.

[0069] Specifically, in the present embodiment, the heat dissipation regulation program used by a certain model of white box switch is taken as an example, and the heat dissipation regulation rule of the white box switch is to monitor the data of 10 temperature sensors. After the heat dissipation regulation software is started, the temperature sensor information and fan information are read through the register of the temperature sensor every 1 minute according to the preset regulation time, including the temperature value, state of the temperature sensor and the fan state, speed value, so as to determine whether the fan state is abnormal according to the fan information, and determine whether there is an over-temperature condition according to the temperature sensor information. It should be noted that the preset regulation time can be set to 1 min, 2 min, etc. according to the actual heat dissipation requirement in the heat dissipation regulation program, which is not specifically limited here.

[0070] In the present embodiment, the heat dissipation regulation program of the network operating system of the white box switch acquires the temperature sensor information and fan information at the preset regulation time, so as to determine the sensor temperature in time and perform over-temperature heat dissipation processing, thereby ensuring the heat dissipation regulation.

[0071] In step 102, the over-temperature condition of the temperature sensor is determined according to the temperature sensor information and the fan information, wherein the over-temperature condition is determined by a preset over-temperature threshold in the configuration file.

[0072] In the embodiment, the network operating system determines whether the fan state is abnormal according to the fan information, and determines whether the over-temperature condition exists according to the temperature sensor information, and it is to be noted that the over-temperature condition is determined by the preset over-temperature threshold in the configuration file, that is, which temperature sensor is over-temperature and the preset over-temperature threshold for determination are both from the configuration file, so that the fan is set to full speed in the over-temperature condition, or the fan speed is regulated in the non-over-temperature condition.

[0073] Specifically, the configuration file includes preset state values of the temperature sensor and the fan speed, a preset over-temperature threshold, a preset regulation mode and other configuration information, in the embodiment, the heat dissipation configuration in the configuration file is in units of temperature sensors, each temperature sensor has a preset over-temperature threshold, two attributes of a preset regulation mode, and a preset regulation mode type, corresponding parameters and other configuration information.

[0074] It is to be noted that the heat dissipation regulation software compares the temperature sensor information and the fan information with the temperature sensor and fan state values in the configuration file, if any temperature sensor or fan state is abnormal, for example, the temperature of the temperature sensor or the speed value of the fan cannot be obtained, it is determined that the system is over-temperature fault, and the fan will be set to full speed for heat dissipation; if the temperature sensor or the fan state is normal, the temperature value of the temperature sensor is compared with the preset over-temperature threshold in the configuration file first, if the temperature value of the temperature sensor is greater than or equal to the preset over-temperature threshold, it is determined that the temperature sensor is over-temperature, then the fan is set to full speed, and the over-temperature times and time are recorded in the temporary file stored in the random read-write memory RAM, if the over-temperature is recovered, the delay according to the recovery time in the configuration file is required to ensure cooling.

[0075] Specifically, step 102 of determining the over-temperature condition of the temperature sensor according to the temperature sensor information and the fan information can include the following steps:

[0076] First, compare the temperature value of the temperature sensor and the speed value of the fan with the preset state values in the configuration file to obtain the temperature sensor or fan state.

[0077] It is to be noted that the preset state values in the configuration file are set according to the actual temperature sensor of the component, and the preset over-temperature threshold is determined according to the optimal working temperature of the switch system and is set in the configuration file, which is not limited here.

[0078] Secondly, if the temperature sensor or fan state is normal, compare the temperature sensor temperature value with the preset over-temperature threshold in the configuration file to determine whether the temperature sensor is over-temperature.

[0079] In this embodiment, the over-temperature condition of the temperature sensor is determined according to the temperature sensor information and the fan information and the preset over-temperature threshold in the configuration file. The white box switch system in this embodiment provides the configuration file, which is convenient for configuration and debugging.

[0080] Step 103: According to the over-temperature condition, obtain the preset control mode in the configuration file, determine the fan target speed, and perform heat dissipation control.

[0081] In this embodiment, the heat dissipation control software obtains the preset control mode in the configuration file according to the over-temperature condition of the temperature sensor. In the case that the temperature sensor is not over-temperature, the control software will select the preset control mode for use according to the configuration file, generate a preset fan speed through the corresponding parameters of the preset control mode, and then determine the maximum value of the preset fan speed corresponding to all temperature sensors as the fan target speed and set it to the fan for heat dissipation control.

[0082] Specifically, according to the over-temperature condition, in the case that the temperature sensor is not over-temperature, the control mode corresponding to the temperature sensor is determined according to the configuration file, the preset fan speed corresponding to the control mode is generated, the maximum value of the preset fan speed corresponding to the control mode is determined as the fan target speed, and heat dissipation control is performed.

[0083] For example, if the temperature of all temperature sensors and the fan speed are normal, the heat dissipation control software will select the preset control mode for use according to the configuration file, wherein the preset control mode in the configuration file includes fixed control, linear control and PID control, and generate a preset fan speed. For example, temperature sensor temp1 adopts linear control with configuration parameters k=2 and b=40 to generate a preset fan speed; and temperature sensor temp2 adopts PID control with configuration parameters p=2, i=1 and d=0.9. It should be noted that the control needs to rely on historical control temperature and speed, and these information and over-temperature time can be saved in RAM cache in json format.

[0084] In this embodiment, the heat dissipation regulation software determines the maximum value as the target fan speed of the fan after generating the preset fan speed corresponding to all temperature sensors, and sets the target fan speed to the fan for heat dissipation regulation. If a temperature sensor continuously over-temperature after the fan runs at full speed, the regulation software will consider that the temperature sensor cannot continue to work normally. The heat dissipation regulation software determines whether the temperature sensor over-temperature multiple times by comparing the reboot_time in the overtemp_method in the configuration file. For example, the reboot_time in temp1 is 5, which means that the temperature sensor over-temperature more than 5 times in 5 speed regulation cycles, and the temperature sensor executes the restart operation. The shutdown_time is 2, which means that the temperature sensor executes the power-off operation after the temperature sensor over-temperature 2 times to continue to protect the machine. In order to record the over-temperature protection situation, the data of each over-temperature needs to be recorded in the temporary file.

[0085] The heat dissipation regulation method provided in the embodiment of the present application obtains the temperature sensor information and the fan information in the preset regulation time, determines the over-temperature situation of the temperature sensor according to the temperature sensor information and the fan information, wherein the over-temperature situation is determined by the preset over-temperature threshold in the configuration file, obtains the preset regulation mode in the configuration file according to the over-temperature situation, determines the target fan speed, and performs heat dissipation regulation. The heat dissipation regulation method in the embodiment of the present application determines the over-temperature situation of the temperature sensor in the preset debugging time, sets the preset regulation mode by using the configuration file to perform heat dissipation regulation, realizes the use of complex speed regulation modes such as linear speed regulation and PID speed regulation in the white box switch, realizes multiple different comprehensive speed regulation modes on different sensors, and realizes the configuration speed regulation method by using the configuration file, which is convenient for adapting to different models of switches, so as to timely adjust the heat dissipation strategy and ensure the stable operation of the system.

[0086] Further, referring to Figure 2 , Figure 2 is Figure 1 The method flowchart of step 103 of the heat dissipation regulation method provided in the embodiment of the present application, step 103 obtains the preset regulation mode in the configuration file according to the over-temperature situation, determines the target fan speed, and performs heat dissipation regulation, comprising:

[0087] Step 1031, in the case that the temperature sensor does not over-temperature, determines the regulation mode corresponding to the temperature sensor according to the configuration file, and generates the preset fan speed corresponding to the regulation mode; wherein the preset regulation mode in the configuration file includes fixed regulation, linear regulation and PID regulation.

[0088] In this embodiment, in the case that the temperature sensor does not over-temperature, the preset regulation mode of the configuration file is determined according to the preset regulation mode of the configuration file, including fixed regulation, linear regulation and PID regulation, and the preset fan speed corresponding to the regulation mode is generated.

[0089] It should be noted that in order to support more fan speed regulation models, the heat dissipation regulation software adds a configuration file to obtain multiple preset regulation modes, and the preset regulation modes are configured in the configuration file, for example, a linear regulation mode according to temperature sensor data, and the preset fan speed can be calculated by the formula k*temp+b, wherein k is a regulation parameter and b is an initial fan speed; for PID regulation, a simplified formula of the commonly used PID algorithm can be referred to, and the heat dissipation regulation software needs to support different preset regulation modes.

[0090] In step 1032, according to the preset fan speed corresponding to the regulation mode, the maximum value in the preset fan speed is determined as the fan target speed, and heat dissipation regulation is performed.

[0091] In this embodiment, different preset regulation modes need to be switched for different temperature sensors, and different coefficients need to be used in the preset regulation mode speed formula, which is realized by further optimizing the configuration file. Specifically, the temperature sensor identifier to be monitored and the preset over-temperature threshold are provided in the configuration file, and in order to support more regulation modes and application platforms, the preset regulation mode type and the corresponding parameters are also marked, for example, fixed regulation static, linear regulation liner and PID regulation pid, and the parameters include k, b and the like of linear regulation. After the regulation software judges that the fan speed does not need to be set to full speed, the preset fan speed corresponding to the regulation mode is calculated according to the regulation mode and the parameters in the configuration file, and if there are multiple preset fan speed results, the maximum value in the preset fan speed is determined as the fan target speed, and heat dissipation regulation is performed.

[0092] In this embodiment, by determining the regulation mode corresponding to the temperature sensor according to the configuration file when the temperature sensor is not over-temperature, the preset fan speed corresponding to the regulation mode is generated, the maximum value in the preset fan speed is determined as the fan target speed according to the preset fan speed corresponding to the regulation mode, and heat dissipation regulation is performed, so that the linear speed regulation, PID speed regulation and other complex speed regulation modes can be used in the white box switch, multiple different comprehensive speed regulation modes can be realized on different temperature sensors, and the configuration speed regulation method is realized through the configuration file, which is convenient for adaptation on different models of switches.

[0093] Further, with reference to Figure 3 , Figure 3 is Figure 1 the method flowchart of step 103 of the heat dissipation regulation method provided in the embodiment of the present application, which is basically the same as the heat dissipation regulation method provided in the first embodiment of the present application, and the difference lies in that step 103 obtains the preset regulation mode in the configuration file according to the over-temperature condition, determines the fan target speed, and performs heat dissipation regulation, and further comprises:

[0094] Step 1033, in the case of temperature sensor overtemperature, record the overtemperature times and time, control the fan full speed operation.

[0095] Step 1034, if the first preset time overtemperature times exceeds the preset overtemperature times, clear the record overtemperature times and time, control system restart, record the restart times and time.

[0096] Step 1035, if the second preset time restart times exceeds the preset restart times, clear the record restart times and time, control system power off, heat dissipation overtemperature protection.

[0097] Specifically, in steps 1031-1035, in order to record the overtemperature protection situation, the data of each overtemperature needs to be recorded in the temporary file. The heat dissipation control software records the overtemperature times and time in the case of temperature sensor overtemperature, controls the fan full speed operation, and carries out heat dissipation control. The heat dissipation control software judges by reading the control information in the temporary file, the overtemp_timestamp column records the last overtemperature time, if a sensor overtemperature occurs, the software will record the time, and the overtemp column of the corresponding sensor will be added by 1, then it is judged whether the overtemperature times exceeds the preset overtemperature times within the first preset time of the configuration file, if the overtemperature times exceeds the preset overtemperature times within the first preset time, the record overtemperature times and time will be cleared, if the overtemperature times exceeds the preset overtemperature times within a short time, the restart operation will be executed, the reboot time needs to be recorded before the restart, the overtemperature related record items are cleared, and the reboot time item is added by 1, and the file is saved. After the restart, if the restart times exceeds the preset restart times within the second preset time, the record restart times and time will be cleared, the system is powered off, and the heat dissipation overtemperature protection is carried out, all records need to be cleared before the power off, and the file is saved.

[0098] It should be noted that the specific execution position of steps 1033-1035 is not limited in this embodiment, in this embodiment, in order to facilitate understanding, steps 1033-1035 are executed after step 1032. In actual use, steps 1033-1035 can also be executed before step 1032, which will not be described one by one here.

[0099] The embodiment of the present application can support over-temperature protection based on the beneficial effects brought by the first embodiment, when the switch system machine is in a serious high temperature situation or fails, the heat dissipation regulation software cannot guarantee the normal heat dissipation of the machine, in order to ensure the safety of the system, the machine is restarted or directly powered off. Further, the technical solution provided by the embodiment can avoid the problem of system downtime or overheating damage caused by serious abnormal heat dissipation, and can perform heat dissipation over-temperature protection according to the heat dissipation regulation result in real time, and maintain the normal operation of the system.

[0100] The second embodiment of the present application relates to a heat dissipation regulation method, which is basically the same as the heat dissipation regulation method provided by the first embodiment of the present application, and the difference lies in that Figure 4 , comprising:

[0101] Step 201, prewrite temperature sensor identification, preset over-temperature threshold, and mark preset regulation mode type and corresponding parameters in the configuration file.

[0102] Specifically, for different temperature sensors, different preset regulation modes need to be switched, and different coefficients need to be used in the preset regulation mode speed formula, which is realized by further optimizing the configuration file. Specifically, prewrite temperature sensor identification, preset over-temperature threshold, and mark preset regulation mode type and corresponding parameters, such as fixed regulation static, linear regulation liner and PID regulation pid, in the configuration file. Parameters include k, b and the like of linear regulation. After the regulation software judges that the machine does not need to set the fan speed to full speed, the preset fan speed corresponding to the regulation mode is calculated according to the regulation mode and parameters in the configuration file, if there are multiple preset fan speed results, the maximum value of the preset fan speed is determined as the fan target speed, and the heat dissipation regulation is performed.

[0103] Step 202, according to the temperature sensor identification, determine the regulation mode of the temperature sensor as one of fixed regulation, linear regulation and PID regulation.

[0104] Step 203, generate the preset fan speed corresponding to the regulation mode according to the preset regulation mode type and corresponding parameters in the configuration file.

[0105] The embodiment of the present application, in addition to the beneficial effects brought by the first embodiment, writes the temperature sensor identifier, the preset over-temperature threshold, the preset control mode type and the corresponding parameters in the configuration file in advance, determines the control mode of the temperature sensor as one of the fixed control, the linear control and the PID control according to the temperature sensor identifier, and generates the preset fan speed corresponding to the control mode according to the preset control mode type and the corresponding parameters in the configuration file. The heat dissipation control method disclosed in the embodiment of the present application uses the configuration file to set the preset control mode for heat dissipation control, generates the preset fan speed corresponding to the control mode, realizes the use of complex speed regulation modes such as linear speed regulation and PID speed regulation in the white box switch, realizes multiple different comprehensive speed regulation modes on different sensors, and realizes the configuration speed regulation method through the configuration file, which is convenient for adaptation on different models of switches, so as to timely adjust the heat dissipation strategy and ensure the stable operation of the system.

[0106] Specifically, step 203 generates the preset fan speed corresponding to the control mode according to the preset control mode type and the corresponding parameters in the configuration file, and further includes:

[0107] The configuration file is modified through the command line to modify the preset over-temperature threshold or the preset control mode type and the corresponding parameters of the temperature sensor, the configuration file modification is detected to be completed, the system is restarted, and it is determined that the modified configuration file takes effect.

[0108] Specifically, for the heat dissipation debugging process in the embodiment, the heat dissipation configuration is often modified, typical scenarios such as modifying the over-temperature threshold of a sensor or the over-temperature protection threshold, and modifying the parameters of the control algorithm during the debugging process can be realized by directly modifying the configuration file. When the configuration file is relatively complex and is not suitable for direct modification, a script program can be provided to modify the configuration file through the command line, and the configuration takes effect after the control software is automatically restarted after modification. The script program can also be used for standardizing and formatting the current heat dissipation configuration information.

[0109] Further, after step 203, the following steps are included:

[0110] The historical control information of the temporary file created in advance is read, the temporary file is used to record the historical control information, and the temperature sensor and fan information obtained in the preset control time are included; if the temporary file is not read, the temporary file is re-created; the control mode corresponding to the temperature sensor in the preset control time is determined according to the historical control information of the temporary file, and the control information recorded in the temporary file is updated.

[0111] It should be noted that part of the regulation mode needs to refer to the temperature sensor temperature value or fan speed data of the last one or two regulation time, for example, the PID regulation mode needs the heat dissipation regulation software to save the data of the past regulation, which can be saved by establishing a temporary file on the storage medium of the white box switch. When the heat dissipation regulation software needs to be regulated, first read the temporary file, if the file does not exist, create a temporary file, and write the default value of the first regulation into the temporary file in a fixed format, then read the file content and update the temporary file each time. In addition, when the sensor reading value recovers from the over-temperature state, it is still necessary to maintain a full-speed speed for a period of time to prevent over-temperature again, at this time, the temporary file can also be used to record the over-temperature time, and the temporary file can be cleared after ensuring that the temperature has been reduced. In the embodiment, the temporary file can be stored in the RAM space.

[0112] The heat dissipation regulation method disclosed in the embodiments of the present application determines the over-temperature condition of the temperature sensor at the preset debugging time, sets the preset regulation mode by using the configuration file to regulate the heat dissipation, realizes the use of complex speed regulation modes such as linear speed regulation and PID speed regulation in the white box switch, can realize multiple different comprehensive speed regulation modes on different sensors, and realizes the configuration of the speed regulation method through the configuration file, which is convenient for adaptation on different models of switches, so as to timely adjust the heat dissipation strategy and ensure the stable operation of the system.

[0113] In order for those skilled in the art to more clearly understand the flow of the heat dissipation regulation method disclosed in the first and second embodiments of the present application, the flow chart of the heat dissipation regulation method provided by the embodiments of the present application is described by taking Figure 5 as an example.

[0114] Step 301, determining whether the preset regulation time is reached.

[0115] Specifically, after the heat dissipation regulation software is started, whether the preset regulation time is reached is determined according to the system time stamp.

[0116] Step 302, obtaining temperature sensor information and fan information.

[0117] For example, the heat dissipation regulation software obtains the temperature sensor information and the fan information, which can read the temperature sensor information and the fan information through the register of the temperature sensor every 1 minute, including the temperature value, the state of the temperature sensor, and the state and speed value of the fan, so as to enter step 303, determining whether the fan state is abnormal according to the fan information, and determining whether there is a temperature sensor abnormality according to the temperature sensor information.

[0118] Step 303, determining whether the temperature sensor and the fan state are normal.

[0119] Step 304, determining whether the temperature sensor is over-temperature.

[0120] Specifically, the network operating system determines whether there is an over-temperature condition according to the obtained temperature sensor and fan information. It should be noted that the over-temperature condition is determined by a preset over-temperature threshold in the configuration file, that is, which temperature sensor is over-temperature and the preset over-temperature threshold for determination are both from the configuration file, so as to determine the over-temperature condition of the temperature sensor, so as to set the fan to full speed in the over-temperature condition, or to control the fan speed in the non-over-temperature condition. If the temperature sensor is not over-temperature, step 305 is entered to determine the temperature sensor corresponding control mode; if the temperature sensor is over-temperature, step 308 is entered to record the over-temperature times and time, and control the fan to run at full speed.

[0121] Step 305, determining the temperature sensor corresponding control mode, generating the preset fan speed corresponding to the control mode.

[0122] Specifically, in the case that the temperature sensor is not over-temperature, the temperature sensor corresponding control mode is determined according to the configuration file, and the preset fan speed corresponding to the control mode is generated,

[0123] For example, if the temperature of all temperature sensors and the fan speed are normal, the heat dissipation control software will select the preset control mode for use according to the configuration file, wherein the preset control mode in the configuration file includes fixed control, linear control and PID control. For example, temperature sensor temp1 adopts linear control, and the configuration parameters are k=2 and b=40 to generate a preset fan speed; and temperature sensor temp2 adopts PID control, and the configuration parameters are p=2, i=1 and d=0.9. This step refers to the foregoing method and will not be described here.

[0124] Step 306, determining the maximum value in the preset fan speed as the fan target speed.

[0125] Specifically, according to the preset fan speed corresponding to the control mode, the maximum value in the preset fan speed is determined as the fan target speed, and heat dissipation control is performed.

[0126] Step 307, performing heat dissipation control according to the fan target speed.

[0127] Step 308, recording the over-temperature times and time, and controlling the fan to run at full speed.

[0128] Specifically, in the case that the temperature sensor is over-temperature, the fan is set to run at full speed, and the over-temperature time is recorded in the temporary file 1 stored in the RAM. If the over-temperature is recovered, the cooling needs to be ensured according to the recovery time item in the configuration file.

[0129] Step 309, determining whether the over-temperature times exceed the preset over-temperature times.

[0130] Step 310, clear the recorded over-temperature times and times, control system restart, record the restart times and times.

[0131] Step 311, judge whether the restart times exceed the preset restart times.

[0132] Step 312, clear the recorded restart times and times, control system power off, and perform heat dissipation over-temperature protection.

[0133] In the embodiment, if the temperature sensor still continuously over-temperature for a long time after the fan full speed, the heat dissipation control software will consider that it cannot continue to work normally, and the heat dissipation control software judges whether multiple over-temperatures occur through reboot_time in overtemp_method, for example, reboot_time in temp1 is 5, that is, it is considered that over-temperature occurs for 5 speed regulation periods to execute the restart machine operation, and shutdown_time is 2, that is, after the continuous occurrence of the restart machine operation for 2 times, the machine is continued to be protected, and the power-off operation is executed. In order to record the over-temperature protection situation, the data of each over-temperature needs to be recorded in the temporary file.

[0134] In the embodiment of the application, the temperature sensor information and the fan information are acquired at the preset control time, the over-temperature situation of the temperature sensor is determined according to the temperature sensor information and the fan information, wherein the over-temperature situation is determined through the preset over-temperature threshold in the configuration file, the preset control mode in the configuration file is acquired according to the over-temperature situation, the target speed of the fan is determined, and heat dissipation control is performed. The heat dissipation control method described in the embodiment of the application determines the over-temperature situation of the temperature sensor at the preset debugging time, uses the configuration file to set the preset control mode for heat dissipation control, realizes the use of complex speed regulation modes such as linear speed regulation and PID speed regulation in a white box switch, can realize multiple different comprehensive speed regulation modes on different sensors, and realizes the configuration speed regulation method through the configuration file, which is convenient for adaptation on different models of switches, so as to timely adjust the heat dissipation strategy and ensure stable operation of the system.
