[0056] The core of the present application is to provide a fan speed measurement method, device, equipment and readable storage medium, which is used to realize automatic measurement of fan speed.

[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0058] Referring to Figure 1 , a flow chart of a fan speed measurement method provided by an embodiment of the present application is shown. The fan speed measurement method provided by an embodiment of the present application is applied to a measurement device connected with a server, and can include:

[0059] S11: calling an interface of a BMC in the server, and setting a plurality of duty cycles for fans in the server in sequence through the interface; the server is placed in a test space with an environmental noise lower than a preset decibel value, and a volume sensor is arranged on the server.

[0060] In the present application, a python script for implementing fan speed measurement is deployed in the measurement device.

[0061] When measuring the speed of the fan in the server, the server can be installed with the fan, and then the server is placed in a test space with an environmental noise lower than a preset decibel value. The size of the preset decibel value can be set according to experience or in combination with the detection capability of the volume sensor, for example, it can be set to 40 decibels. Wherein, placing the server in a test space with an environmental noise lower than a preset decibel value means placing the server in a quiet test space to avoid the influence of subsequent environmental noise on the fan decibel value measurement, thereby improving the accuracy of fan speed measurement. It should be noted that the fan in the present application is specifically a PWM (Pulse Width Modulation) fan.

[0062] After placing the server in a test space with an environmental noise lower than a preset decibel value, the server can be connected to the measurement device through a network cable or the like, so that they can communicate with each other. In addition, a volume sensor also needs to be installed in the server, wherein the volume sensor can be installed near the fan in the server or directly on the fan to facilitate the measurement of the fan decibel value.

[0063] After the above preparation work is completed, the measurement device can simulate a restful interface through the deployed python script to log in to the BMC (Basement management controller) in the server, and set a plurality of duty cycles for the fan in the server through the BMC fan interface. Specifically, the measurement device logs in to the BMC in the server through the deployed python script and calls the interface (specifically, the restful interface) of the BMC in the server, and sets a plurality of duty cycles for the fan in the server through the interface, so that the fan in the server runs at the set duty cycles.

[0064] In combination with the actual working condition of the fan, the fan can be set with 20%, 50%, 80%, and 100% duty cycles, of course, if the fan can work at other duty cycles, other duty cycles can also be set for the fan.

[0065] It should be noted that in the above-mentioned setting of a plurality of duty cycles in sequence, there can be a certain time interval between the setting of adjacent two duty cycles (the size of the time interval can be determined according to actual experience), so that the fan can work stably for a certain time according to the set duty cycle, thereby improving the accuracy of decibel value measurement, and thus facilitating the improvement of the accuracy of fan speed measurement, and at the same time avoiding the influence on the working performance of the fan through the above-mentioned operation.

[0066] S12: Obtain the decibel value corresponding to each duty cycle of the fan measured by the volume sensor, and construct the corresponding relationship between the duty cycle and the decibel value according to the duty cycle and the decibel value.

[0067] On the basis of step S11, a duty cycle is set for each fan in the server, and the volume sensor can measure the decibel value corresponding to the set duty cycle of the fan, and the python script deployed in the measurement device can obtain the decibel value corresponding to the set duty cycle of the fan measured by the volume sensor through the restful interface of the BMC. Therefore, the python script deployed in the measurement device can obtain the decibel value corresponding to each duty cycle set in step S11 respectively through the restful interface of the BMC.

[0068] On the basis of the above, the python script deployed in the measurement device can construct the corresponding relationship between the duty cycle and the decibel value according to the set duty cycle and the decibel value corresponding to the set duty cycle, and can store the constructed corresponding relationship, so as to facilitate subsequent measurement of the fan speed based on the corresponding relationship.

[0069] S13: Obtain the current decibel value of the fan measured by the volume sensor, and determine the current duty cycle corresponding to the current decibel value according to the corresponding relationship.

[0070] When it is necessary to measure the fan speed (for example, receiving a fan speed measurement instruction or the current condition meeting a fan speed measurement strategy (such as a strategy of measuring the fan speed at a fixed time)), the python script deployed in the measurement device can control the volume sensor to measure the current decibel value of the fan through the restful interface of the BMC (of course, the volume sensor can also measure the decibel value of the fan at all times to prepare for the fan speed measurement), and obtain the current decibel value of the fan in the server measured by the volume sensor through the restful interface of the BMC. Then, the current duty cycle corresponding to the current decibel value can be determined according to the corresponding relationship between the duty cycle and the decibel value constructed in step S12 and the current decibel value of the fan measured by the volume sensor, that is, the duty cycle corresponding to the current working of the fan in the server is obtained.

[0071] S14: Obtain the speed of the fan according to the current duty cycle.

[0072] After obtaining the current duty cycle of the fan, the speed of the fan can be obtained according to the current duty cycle. Specifically, the current duty cycle of the fan can be multiplied by the maximum speed of the fan to obtain the speed of the fan.

[0073] It should be noted that after step S13, the python script deployed in the measurement device can also obtain the duty ratio of the fan itself through the restful interface of the BMC, and compare the current duty ratio obtained in step S13 with the duty ratio of the fan itself. If the two are consistent, it indicates that the fan does not exist abnormally, and if the two are inconsistent, it indicates that the fan speed exists abnormally.

[0074] Through the above process, it can be known that the application utilizes the measurement device connected with the server to realize the automatic measurement of the fan speed in the server, without the need for manual participation in the fan speed measurement process, and without the need for disassembling the fan from the server. Therefore, the complexity of fan speed measurement can be reduced, the human cost of fan measurement can be reduced, and the convenience and efficiency of fan speed measurement can be improved.

[0075] The above technical solution disclosed in the application utilizes the measurement device connected with the server to call the interface of the BMC in the server, sets multiple duty ratios for the fan in the server through the interface in sequence, obtains the decibel values corresponding to the set duty ratios respectively measured by the volume sensor arranged on the server, and constructs the corresponding relationship between the duty ratio and the decibel value according to the set duty ratios and the decibel values corresponding to the duty ratios. Then, the current duty ratio of the fan measured by the volume sensor is obtained, the current duty ratio corresponding to the current decibel value is determined according to the current duty ratio of the fan and the constructed corresponding relationship, and the fan speed is obtained according to the current duty ratio. That is, the application realizes the automatic measurement of the fan speed through the measurement device, without the need for manual participation, so as to reduce the human consumption, reduce the measurement complexity and measurement cost, and improve the fan speed measurement efficiency. Placing the server in a test space with an environmental noise lower than a preset decibel value can reduce the influence of the environmental noise on the fan decibel value measurement, and improve the accuracy of the fan speed measurement.

[0076] Specifically, reference can be made to Figure 2 which shows a flowchart of another fan speed measurement method provided by an embodiment of the application. The fan speed measurement method provided by an embodiment of the application can include:

[0077] obtaining the real-time decibel value corresponding to the fan and the duty ratio measured by the volume sensor;

[0078] determining whether the real-time decibel value does not change within a preset time length;

[0079] If yes, the real-time decibel value is taken as the decibel value corresponding to the fan and the duty ratio.

[0080] In the present application, when obtaining the fan and the corresponding duty cycle of the volume sensor measurement of the decibel value, the real-time decibel value of the fan and the duty cycle corresponding to the volume sensor measurement can be obtained, and then it can be judged whether the real-time decibel value changes within a preset time length, wherein the preset time length mentioned here can be less than the aforementioned certain time interval, for example, the preset time length can be 10s.

[0081] If the real-time decibel value changes within the preset time length, it indicates that the fan is not working stably at this duty cycle, therefore, in order to improve the accuracy of the fan speed measurement, the real-time decibel value obtained at this time can not be used as the final decibel value corresponding to the duty cycle. If the real-time decibel value does not change within the preset time length, it indicates that the fan is working stably at this duty cycle, and at this time, the real-time decibel value obtained by the volume sensor measurement can be used as the final decibel value corresponding to the duty cycle.

[0082] It should be noted that for each duty cycle set, the final corresponding decibel value is determined in the above manner to improve the accuracy of the corresponding decibel value determination, thereby improving the accuracy of the corresponding relationship determination, and further improving the accuracy of the fan speed measurement.

[0083] The fan speed measurement method provided by the embodiments of the present application sets a plurality of duty cycles for the fan in the server through the interface, which can include:

[0084] The duty cycles are set from low to high and then from high to low for the fan through the interface.

[0085] Alternatively, the duty cycles are set from high to low and then from low to high for the fan through the interface.

[0086] In the present application, when a plurality of duty cycles are set for the fan in the server through the interface, the duty cycles can be set from high to low and then from low to high for the fan through the interface. Taking the set duty cycles of 20%, 50%, 80%, and 100% as an example, the duty cycle of the fan can be set to 20%, 50%, 80%, and 100% in turn, and then the duty cycle of the fan can be set to 100%, 80%, 50%, and 20% in turn.

[0087] Alternatively, the duty cycles are set from high to low and then from low to high for the fan through the interface. Taking the set duty cycles of 20%, 50%, 80%, and 100% as an example, the duty cycle of the fan can be set to 100%, 80%, 50%, and 20% in turn, and then the duty cycle of the fan can be set to 20%, 50%, 80%, and 100% in turn.

[0088] The fan duty cycle setting mode (from high to low, from low to high) can be used to set the fan duty cycle, so as to cover various working modes of the fan, thereby improving the accuracy of the corresponding relationship acquisition, and improving the accuracy of the fan speed measurement.

[0089] The fan speed measurement method provided by the embodiment of the application can include the following steps:

[0090] The steps of setting multiple duty cycles for the fan in the server through the interface and the steps of obtaining the decibel value corresponding to each duty cycle measured by the volume sensor are repeatedly executed for a preset number of times;

[0091] The average decibel value corresponding to each duty cycle is calculated to obtain the corresponding relationship.

[0092] In the application, when the corresponding relationship between the duty cycle and the decibel value is constructed according to the duty cycle and the decibel value, the python script can repeatedly execute the steps of setting multiple duty cycles for the fan in the server through the interface and the steps of obtaining the decibel value corresponding to each duty cycle measured by the volume sensor for a preset number of times, wherein the preset number of times can be set according to actual experience, for example, the python script can be repeated 1000-2000 times. Then, the average decibel value corresponding to each duty cycle can be calculated according to the decibel value corresponding to each duty cycle obtained each time, to obtain the corresponding relationship between the duty cycle and the decibel value (here, the decibel value is the average decibel value), that is, the corresponding relationship between the duty cycle a, b, c, d and the decibel value e, f, g, h.

[0093] The method of repeatedly setting a preset number of times and calculating the average decibel value corresponding to each duty cycle to obtain the corresponding relationship can improve the accuracy of the decibel value calculation, thereby facilitating the improvement of the accuracy of the fan speed measurement.

[0094] Of course, after calculating the average decibel value corresponding to each duty cycle, the corresponding relationship expression can also be obtained according to the duty cycle and the corresponding average decibel value, so as to directly calculate the current duty cycle according to the corresponding relationship expression and the current decibel value, thereby calculating the fan speed.

[0095] The fan speed measurement method provided by the embodiment of the application can further include the following steps after obtaining the current decibel value of the fan measured by the volume sensor:

[0096] Determine the decibel value error range corresponding to the current decibel value;

[0097] Determine whether there is only one decibel value in the corresponding relationship within the decibel value error range;

[0098] If yes, the current duty cycle corresponding to the current decibel value is determined according to the correspondence, which can include:

[0099] The duty cycle corresponding to the only one decibel value in the correspondence is taken as the current duty cycle corresponding to the current decibel value.

[0100] In the present application, on the basis of calculating the average decibel value corresponding to each duty cycle to obtain the correspondence, after obtaining the current decibel value of the fan measured by the volume sensor, the decibel value error range corresponding to the current decibel value can be determined according to the pre-determined error range (determined according to the accuracy of the volume sensor). After determining the decibel value error range corresponding to the current decibel value, it is judged whether there is only one decibel value in the correspondence within the decibel value error range, if it is determined that there is only one decibel value in the correspondence within the determined decibel value error range, it indicates that there is no abnormal situation affecting the fan speed measurement, on this basis, the process of determining the current duty cycle corresponding to the current decibel value according to the correspondence is: obtaining the duty cycle corresponding to the only one decibel value from the obtained correspondence, and taking the obtained duty cycle corresponding to the only one decibel value as the current duty cycle, so as to improve the accuracy of the fan speed measurement.

[0101] Taking the current decibel value as x and the error range as ±5% as an example, the decibel value error range corresponding to the current decibel value is 0.95x-1.05x, at this time, it can be judged whether there is only one decibel value in the obtained correspondence within 0.95x-1.05x, that is, it is determined whether 0.95x-1.05x covers one decibel value in the correspondence and the decibel value is unique.

[0102] Specifically, it can be seen from Figure 3 which shows a schematic diagram of verifying the fan provided by the embodiment of the present application. After determining the current duty cycle by the above-mentioned manner, the python script can also obtain the duty cycle of the fan through the restful interface, and compare the current duty cycle with the duty cycle of the fan, if they are consistent, it indicates that the fan does not exist abnormal, the test is passed, if they are inconsistent, it indicates that the fan speed is abnormal, the test is not passed.

[0103] The fan speed measurement method provided by the embodiment of the present application can further include:

[0104] The number of times of repeating the steps of sequentially setting a plurality of duty cycles for the fan in the server through the interface and obtaining the decibel value of the fan corresponding to each duty cycle measured by the volume sensor is increased;

[0105] The average decibel value corresponding to each duty cycle is recalculated to obtain a new correspondence;

[0106] obtaining a current decibel value of the fan measured by the volume sensor, determining a decibel value error range corresponding to the current decibel value;

[0107] judging whether there is only one decibel value in the new corresponding relationship located in the decibel value error range;

[0108] if yes, determining a current duty cycle corresponding to the current decibel value according to the corresponding relationship, which can comprise:

[0109] taking the duty cycle corresponding to the only one decibel value in the new corresponding relationship as the current duty cycle corresponding to the current decibel value.

[0110] In the present application, if it is determined that there is not only one decibel value in the corresponding relationship located in the decibel value error range, specifically, if it is determined that there is not any decibel value in the corresponding relationship located in the decibel value error range, or there are at least two decibel values in the corresponding relationship located in the decibel value error range, it indicates that there is an abnormal situation, and the abnormal situation can be that the repeated preset number of times is too small, which can be specifically referred to in Figure 4 which shows an abnormal situation processing schematic diagram provided by the embodiments of the present application. Therefore, after it is determined that there is not only one decibel value in the corresponding relationship located in the decibel value error range, the number of times of repeatedly executing the steps of sequentially setting multiple duty cycles for the fan in the server through the interface and the steps of obtaining the decibel values of the fan corresponding to each duty cycle measured by the volume sensor can be increased (the increased number of times can be the same as the preset number of times, or can be set according to experience). Then, the average decibel values corresponding to each duty cycle are recalculated according to the repeated preset number of times and the increased repeated number of times, so as to obtain a new corresponding relationship (i.e. to obtain the relationship between each duty cycle and the recalculated average decibel value). Then, the current decibel value of the fan obtained by the volume sensor can be obtained, the decibel value error range corresponding to the current decibel value is determined, and it is judged whether there is only one decibel value in the obtained new corresponding relationship located in the decibel value error range. If yes, the duty cycle corresponding to the only one decibel value is obtained from the obtained new corresponding relationship, and the obtained duty cycle corresponding to the only one decibel value is taken as the current duty cycle, so as to improve the accuracy of the fan speed measurement.

[0111] It should be noted that the above-mentioned process is similar to the process performed after the repeated preset number of times mentioned before, which will not be described here.

[0112] The fan speed measurement method provided by the embodiments of the present application can further comprise:

[0113] detecting whether the environmental noise exceeds a preset decibel value;

[0114] If yes, output a prompt that there is environmental noise influence;

[0115] If no, output a prompt that the fan rotation speed is abnormal.

[0116] In the present application, after increasing the number of repetitions and obtaining a new corresponding relationship, and re-determining, if it is determined that there is not a unique decibel value in the new corresponding relationship within the decibel value error range, it indicates that it is not that the number of repetitions is too small to cause the above-mentioned situation, but it may be caused by environmental noise or fan rotation speed abnormality. Therefore, it can be detected whether the environmental noise exceeds the preset decibel value. Specifically, the fan can be controlled to stop running, and the volume sensor can be controlled to measure the decibel value after the fan stops running (the decibel value is the environmental noise), and the decibel value measured by the volume sensor after the fan stops running is obtained. Then, it is determined whether the decibel value measured by the volume sensor after the fan stops running exceeds the preset decibel value. If yes, it is determined that the environmental noise exceeds the preset decibel value. If no, it is determined that the environmental noise does not exceed the preset decibel value.

[0117] If it is determined that the environmental noise exceeds the preset decibel value, it indicates that there is other noise in the environment that affects the fan rotation speed measurement. Therefore, a prompt that there is environmental noise influence can be output, so that relevant personnel can replace the test space or remove the environmental noise according to the prompt, thereby reducing the influence of environmental noise and improving the accuracy of fan rotation speed measurement.

[0118] If it is determined that the environmental noise does not exceed the preset decibel value, it indicates that there is no other noise in the environment that affects the fan rotation speed measurement, but the fan rotation speed is abnormal. At this time, a prompt that the fan rotation speed is abnormal can be output, so that relevant personnel can troubleshoot the fan according to the prompt, thereby facilitating the continuation of fan rotation speed measurement.

[0119] The present application also provides a fan rotation speed measurement device, which is applied to a measurement equipment connected with a server, as shown in Figure 5 which shows a structural schematic diagram of a fan rotation speed measurement device provided by an embodiment of the present application, and can include:
