Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
At present, the fan speed regulation has poor efficiency, the scheme control processing is not simplified enough, a step speed regulation mode and a return difference speed regulation mode are required to be selected, the fan speed is calculated according to the current temperature, the initial temperature, the temperature stepping value and the initial speed value, and the fan speed is set. When temperature slowly changes, then fan rotational speed adjustment also can be slow, and the radiating effect promotes not rapidly to the fan can produce the noise of continuous variation, also can influence user experience.
The fan speed regulation stability is poor, and the scheme does not carry out filtering treatment on the collected temperature data. When the temperature of the sensor is in instantaneous jitter, the acquired temperature data is not real, and after the temperature data is fed back to the fan control, the rotating speed of the fan can be regulated up or down, the regulation of the rotating speed of the fan can be unstable, and larger energy consumption and noise are generated.
The fan control universality is poor, the parameters such as the current temperature, the initial temperature, the temperature stepping value, the initial rotating speed value and the like are required to be associated, when the environment scene of the applied equipment changes, the related modification is large, and the universality of the application on different equipment platforms is poor.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a fan speed regulating method based on equipment provided by an embodiment of the application. The process may be performed by computing devices in the respective areas, with some input parameters or intermediate results in the process allowing manual intervention adjustments to help improve accuracy.
The implementation of the analysis method according to the embodiment of the present application may be a terminal device or a server, which is not particularly limited in the present application. For ease of understanding and description, the following embodiments are described in detail with reference to a server.
It should be noted that the server may be a single device, or may be a system formed by a plurality of devices, that is, a distributed server, which is not particularly limited in the present application.
The flow in fig. 1 may include the following:
s102: and in a preset period, acquiring a plurality of first temperature values corresponding to the equipment through a plurality of temperature sensors arranged on the equipment.
The device may be a switch device, and the switch device has a plurality of temperature sensors distributed on each hardware module of the switch device, for example, a power module, a CPU chip, a service chip, and the like.
For example, the temperature acquisition module may acquire a temperature value from a temperature sensor on the switch device via a hardware bus.
S104: and respectively carrying out jitter elimination treatment on the plurality of first temperature values through a preset median filtering algorithm to obtain a plurality of second temperature values.
In some embodiments of the present application, a median filtering algorithm is used to filter out unstable temperature data reported by the temperature sensor, and eliminate jitter of the temperature data. Generally, the temperature change of the device is linear, and the temperature value does not increase or decrease instantaneously in the process of timing sampling. In order to ensure the accuracy of the first temperature value acquired from the temperature sensor, the application eliminates the jitter of the first temperature value through a median filtering algorithm so as to improve the stability of fan control.
Because of the median filtering algorithm, the method has good filtering effect on nonlinear shot noise and good edge protection characteristic, but ordering statistics in the method have a certain influence on performance. The larger the data volume in the window is, the larger the overhead caused by the realization of the sorting is, and the real-time performance of the filtering processing is affected, so that the proper window data volume is required to be extracted according to the data characteristics of the actual application scene.
Specifically, a temperature sensor corresponding to the first temperature value is first determined, and the window array is updated by determining the window position corresponding to the first temperature value in the window array of the temperature sensor. Wherein the window array comprises a plurality of historical temperature values. And then, acquiring a preset number of temperature values in the updated window array, and sequencing the preset number of temperature values according to ascending order to obtain a sequenced temperature data queue. And then, removing the maximum temperature value and the minimum temperature value in the ordered temperature data queue, and determining the rest temperature value. Finally, the remaining temperature values are averaged, and the average value is taken as a second temperature value of the first temperature value.
Further, when determining the corresponding window position, performing modular operation on the first temperature value according to the data capacity of the window array of the temperature sensor to obtain a remainder of the first temperature value. Then, according to a preset rule and a remainder, an expression of the first temperature value in the window array is determined. Then, according to the expression, determining the position of the corresponding window in the window array of the first temperature value.
When updating, the first temperature value is firstly determined to be at the corresponding window position in the window array of the temperature sensor, and then the window array is updated by replacing the historical temperature value of the window position with the first temperature value.
More intuitively, fig. 2 is an exemplary diagram of a median filtering process provided in an embodiment of the present application.
As shown in fig. 2, for the a sensor, in constructing the window array of the a sensor, the following is specific:
first, the maximum data capacity of the sliding window array is set to 5, the window array is expressed as Y [ ], and the number of elements is set to 5.
Then, for each acquired first temperature value Y, the current count statistic value count is reserved. Then, modulo operation is carried out on the count value count pair 5 of the collected first temperature value Y, and i is the remainder of count Mod 5. The calculated value i is input as a first temperature value Y to the window array index, that is, the position of the first temperature value Y in the window, and the range of the value i is [0,4]. Through the above-mentioned cyclic modular operation, the first temperature value of the A sensor acquired in a cyclic manner can be updated to the position of the window array Y [ i ] in turn. That is, Y [ i ] represents that the first temperature value is at the i-th position of the window array, thereby constructing the window array.
When the first temperature value is required to be acquired during the jitter elimination processing, 5 sample values { y [0], y [1], y [2], y [3], y [4] are taken from the window array, and then the 5 sample values are rapidly ordered in ascending order to sequentially obtain Yn-2, yn-1, yn, yn+1 and Yn+2.
That is, in fig. 2, the minimum value Yn-2 and the maximum value yn+2 are removed, the middle three values Yn-1, yn and yn+1 are reserved, and then, the three values Yn-1, yn and yn+1 are averaged, so that the average value is calculated as the filtered temperature output value, that is, the second temperature value.
S106: and selecting a temperature value with the highest temperature value from the plurality of second temperature values, and taking the temperature value with the highest temperature value as a third temperature value.
S108: and comparing the third temperature value with a set temperature threshold to determine a temperature alarm level corresponding to the equipment.
In some embodiments of the present application, the preset temperature threshold may include a low threshold, a medium threshold, and a high threshold by depending on the severity of the third temperature value. The interval ranges of the three temperature thresholds correspond to different temperature alarm levels. It should be noted that, no alarm is given when the third temperature value is smaller than the low threshold.
And if the temperature alarm level is consistent with the temperature alarm level of the previous period, keeping the current rotating speed value of the fan on the equipment unchanged.
If the temperature alarm level is inconsistent with the temperature alarm level of the previous cycle, the step S110 is continuously executed.
S110: and if the temperature alarm level is inconsistent with the temperature alarm level of the previous period, determining a fan rotating speed gear corresponding to the temperature alarm level according to a preset mapping relation.
The system is started, and then a temperature acquisition module and a fan control module are enabled. The fan control module adopts an improved control strategy to set three temperatures and four fan speed gears. And judging whether the acquired third temperature value reaches the condition of a set temperature threshold, and selecting the fan rotating speed of the corresponding gear.
In some embodiments of the application, the temperature alert levels include a low level, a high level, and a severity level for the span of the three temperature thresholds. The interval ranges of the three temperature thresholds correspond to a basic gear, a low-speed gear, a high-speed gear and a full-speed gear of the rotating speed of the fan respectively. That is, different temperature alert levels correspond to different fan speed gears. The basic gear is the normal basic rotation speed of the fan set by the system. The fan is guaranteed not to generate backflow, and noise influence is considered.
More intuitively, the mapping is shown in table 1.
Table 1:
| alarm level | Temperature threshold range | Rotational speed gear | Rotational speed of fan |
| T < low threshold | Basic gear | 40％ | |
| Low grade of | The low threshold is less than or equal to T and less than the middle threshold | Low gear | 60％ |
| High grade | The middle threshold is less than or equal to T and less than the high threshold | High speed gear | 80％ |
| Severity grade | High threshold < T | Full speed gear | 100％ |
Specifically, if the temperature alarm level is a low level, determining that the fan rotation speed gear corresponding to the temperature alarm level is a low speed gear according to a preset mapping relation.
If the temperature alarm level is high, determining that the fan rotating speed gear corresponding to the temperature alarm level is high according to a preset mapping relation.
If the temperature alarm level is a serious level, determining that the fan rotating speed gear corresponding to the temperature alarm level is a full speed gear according to a preset mapping relation. The rotating speed value of the low-speed gear is smaller than that of the high-speed gear, and the rotating speed value of the high-speed gear is smaller than that of the full-speed gear.
It should be noted that, T represents the third temperature value, in the T-based gear, the rotational speed is 40% of the rotational speed value of the full-speed gear, in the T-low gear, the rotational speed is 60% of the rotational speed value of the full-speed gear, in the T-high gear, the rotational speed is 80% of the rotational speed value of the full-speed gear, in the T-full gear, the rotational speed is 100% of the rotational speed value of the full-speed gear.
When determining the mapping relationship, firstly converting the sample third temperature value into a sample pulse width modulation value of the fan, and converting the sample pulse width modulation value into a sample fan rotating speed value so as to determine the mapping relationship between the sample third temperature value and the sample fan rotating speed value. The calculation formula between the sample third temperature value and the sample pulse width modulation value of the fan is as follows: PWM value=4.54×t correction value. The T correction value is a filtered sample third temperature value, and the PWM value is a sample pulse width modulation value.
Then, according to the temperature alarm level corresponding to the third temperature value of the sample and the fan rotation speed gear corresponding to the fan rotation speed value of the sample, a mapping relation table between the temperature alarm level and the fan rotation speed gear, namely table 1, is determined.
That is, it is understood that the fan control module selects the fan speed gear of the corresponding temperature range according to the temperature change. When the temperature increases, the fan control module automatically increases the fan speed to a higher level. And then continuously monitoring the temperature change, and keeping the current rotating speed to stably run when the temperature does not rise to a higher threshold. The fan control module will also automatically adjust the fan to the corresponding rotational speed if the device temperature begins to drop to a lower threshold.
S112: and controlling the fan on the equipment to regulate the speed according to the rotating speed gear of the fan.
Specifically, according to the fan rotation speed gear, a corresponding fan rotation speed value is determined. Then, the fan rotating speed value is converted into a pulse width modulation value, and the fan on the equipment is controlled to regulate the speed according to the pulse width modulation value. The calculation formula of the fan rotation speed value and the pulse width modulation value is as follows: fan speed value percentage = PWM value/255 x 100%. Wherein the PWM value is a pulse width modulation value.
It should be noted that, although the embodiment of the present application is described with reference to fig. 1 for sequentially describing steps S102 to S112, this does not represent that steps S102 to S112 must be performed in strict sequence. The steps S102 to S112 are sequentially described according to the sequence shown in fig. 1 according to the embodiment of the present application, so as to facilitate the understanding of the technical solution of the embodiment of the present application by those skilled in the art. In other words, in the embodiment of the present application, the sequence between the steps S102 to S112 may be appropriately adjusted according to the actual needs.
The method of fig. 1 simplifies the fan control process, and the third temperature value and the fan rotation speed are classified into a plurality of levels according to the severity by setting a temperature threshold and a fan rotation speed gear. And respectively calculating the mapping relation between each alarm level and the fan rotating speed gear in advance according to the calculation formulas of the temperature and the fan rotating speed. And when the detected equipment temperature reaches the temperature threshold range, immediately adjusting the fan to the rotating speed value of the corresponding gear. The fixed table adopted by the mapping relation between the alarm level and the fan rotating speed gear is directly checked, real-time calculation is not needed, complex arbitration logic is omitted, the control flow is simplified, the fan speed regulation response is faster, and the heat dissipation effect feedback of the equipment is rapid.
The fan speed regulation stability is higher, and the scheme adopts the median filtering algorithm to process the first temperature value, so that the shake of the temperature of the sensor can be filtered, and the acquired first temperature value is more accurate. After the filtering treatment, the third temperature value input to the fan control module is stable, the fan rotating speed is adjusted according to the third temperature value, the fan rotating speed is not dithered, the stability of the fan rotating speed adjustment is higher, and meanwhile, the energy consumption and the noise of equipment are reduced.
On different equipment platforms, the temperature threshold and the fan rotating speed gear are also different due to the differences of the hardware structure, the number of fans and the heat dissipation design of the equipment. The scheme reduces parameters affecting the speed regulating function of the fan to a speed gear which only depends on a temperature threshold. The temperature threshold and the rotating speed are set to different levels, and the values in the temperature threshold and the fan rotating speed mapping table can be flexibly set according to the applied equipment scenes. Therefore, the fan control strategy in the scheme can be suitable for different equipment platforms, and the module is more convenient to transplant and has better universality.
