Detailed Description
The following detailed description of preferred embodiments of the present application will be made with reference to the accompanying drawings, which first illustrate a first aspect of the embodiments of the present disclosure: referring to fig. 1, the system includes at least one network device and at least one computing device, and it is added that the network device is installed with a fan. In the implementation process, data interaction can be performed between the computing device and the network device, common computing devices include computers, tablet computers and the like, and here, a method for executing fan speed regulation by using a computer as the computing device is described. In the second case: the method for directly executing the fan speed regulation by the network equipment omits the process of acquiring the operation parameters of the network equipment by the external computing equipment under the condition.
Referring to fig. 2, a case of a method for executing fan speed regulation by a computing device is described below, in an embodiment of the present disclosure, a specific flow of the method for executing fan speed regulation by a computing device is as follows:
step 201: the method comprises the steps of obtaining the current running state of the network equipment, and determining a first speed regulation parameter and a second speed regulation parameter of a fan based on the proportional relation between the current running state and the preset full-load running state, wherein the fan is installed in the network equipment, the first speed regulation parameter and the second speed regulation parameter are both used for representing the influence of the proportional relation on the actual rotating speed of the fan, and the second speed regulation parameter is related to a power consumption device.
Generally, a network device is responsible for data processing tasks of several orders of magnitude, but in an actual operation process, when received data processing instructions are different, loads carried by the network device are also different, and data volumes processed by the network device are also greatly different, that is, operation power consumption of the network device is continuously changed along with the data volumes processed by the network device. Therefore, in the implementation process, the current operation state of the network device is obtained in real time, and it should be noted that the current operation state may be current operation power consumption, current utilization rate of the central processing unit, and the like, for example, when the current operation state is the current operation power consumption, the current voltage and the current of the network device are obtained, and the current operation power consumption is calculated by using the current voltage and the current.
And the fan is installed in the network equipment, the specific position of the fan in the network equipment can be flexibly set according to the specific use scene, and the fan is used for cooling the network equipment.
In addition, it should be further explained that, before acquiring the current operating state of the network device, acquiring the full operating state of the network device in advance is further included, which specifically includes:
(1) And controlling the full-load operation of the network equipment, and collecting the full-load voltage and the full-load current of the network equipment under the full-load operation.
In the implementation process, the full-load operation of the network equipment is controlled by the way that the computing equipment sends a data processing instruction to the network equipment, and the like, so as to obtain the maximum operation power consumption of the network equipment, namely the full-load operation state. The network equipment monitoring device is characterized in that the network equipment monitoring device can be externally connected with a monitoring unit, full-load voltage and full-load current of network equipment under full-load operation are collected through the monitoring unit, and the full-load voltage and the full-load current are both for the whole network equipment.
(2) And calculating the full-load running state of the network equipment according to the full-load voltage and the full-load current.
After the full-load voltage and the full-load current are collected, the full-load running state of the network equipment is calculated by multiplying the full-load voltage and the full-load current.
Preferably, the above (1) and (2) correspond to the case that the current operation state is the current operation power consumption and the full-load operation state is the full-load operation power consumption, if the current operation state is the utilization rate of the current central processing unit, the current operation power consumption of the central processing unit can also be determined by monitoring the current voltage and current of the current central processing unit, and the full-load voltage and full-load current of the current central processing unit are collected to determine the full-load operation state of the central processing unit.
After the current operating state and the full-load operating state are obtained, calculating a proportional relation between the current operating state and the full-load operating state to determine a first speed regulation parameter and a second speed regulation parameter of the fan, wherein the first speed regulation parameter and the second speed regulation parameter are both used for representing the influence of the proportional relation on the actual rotating speed of the fan, and the second speed regulation parameter is related to a power consumption device, namely when the actual rotating speed of the fan is specifically calculated, the first speed regulation parameter and the second speed regulation parameter play a certain role, namely the current operating state condition of the network equipment is considered. The following describes the determination of the speed-adjusting parameters:
the first mode is as follows: based on the proportional relation between the current operating state and the preset full-load operating state, determining a first speed-regulating parameter of the fan, referring to fig. 3, including:
step 2011: and determining a corresponding environment coefficient based on the current environment temperature and the current running state, wherein the environment coefficient is used for representing the ratio relation between the actual rotating speed of the fan and the environment temperature value.
The environment coefficient is used for representing the ratio relation between the actual rotating speed of the fan and the environment temperature value, namely the environment coefficient is determined according to the environment temperature value, the operation power consumption and the actual rotating speed of the fan. Therefore, before determining the corresponding environmental coefficient based on the current environmental temperature and the current operating state, the environmental coefficients of the fan in different operating power consumption sections are further determined, so as to prepare for determining the environmental coefficients according to the current operating state, as shown in fig. 4, specifically including:
step 20100: and acquiring the range of the ambient temperature which can be borne by the network equipment.
Typically, each type of network device can carry different ambient temperature ranges, resulting in different fan speeds required by the network device. For example, when the ambient temperature range that the network device 1 can carry is 5-100 degrees celsius, then when the ambient temperature that the network device 1 is located is 10 degrees celsius, a relatively small rotation speed is required to maintain the normal operation of the network device; when the ambient temperature of the network device 1 is 100 degrees celsius, a relatively large rotation speed is required to maintain the normal operation of the network device.
In the implementation process, in order to consider the influence of the ambient temperature on the fan speed regulation, the ambient temperature range that can be borne by the network device is obtained first, and for example, the ambient temperature range can be obtained according to the type and model of the network device.
Step 20101: and in each environment temperature interval corresponding to the environment temperature range, controlling the running power consumption of the network equipment to run from no-load power consumption to full-load running state, and respectively collecting the actual rotating speed of each fan corresponding to each running power consumption interval between the no-load power consumption and the full-load running state.
In the implementation process, after the environment temperature range is obtained, in each environment temperature interval corresponding to the environment temperature range, that is, each environment temperature interval of the whole environment temperature range is traversed, and in order to reduce the calculation amount, the processing can be performed by taking the environment temperature interval as a unit, that is, the point calculation of a plurality of environment temperature values is converted into the calculation of a plurality of continuous environment temperature intervals.
On the basis of considering the influence of the environment temperature on the fan speed regulation, the influence of the running power consumption condition of the network equipment on the fan speed regulation is also considered, therefore, when the network equipment is in each environment temperature interval, the running power consumption of the network equipment is controlled to run from no-load power consumption to full-load running state, namely, various running conditions of the network equipment are simulated in different environment temperature values, and the actual rotating speeds of the fans corresponding to the running power consumption intervals between the no-load power consumption and the full-load running state are respectively collected, namely, the actual rotating speeds of the fans corresponding to the different running power consumption conditions in different environment temperature values are obtained.
Step 20102: and determining the environmental coefficients of the fans in different operation power consumption sections based on the environment temperature sections, the operation power consumption sections and the actual rotating speeds of the fans.
After obtaining each environment temperature interval and each fan actual rotating speed, calculating a ratio between two difference values of the difference value of each fan actual rotating speed and the difference value of the corresponding environment temperature value aiming at the operation power consumption corresponding to each operation power consumption interval, wherein the ratio is the environment coefficient of the fan under the operation power consumption. And by analogy, calculating a plurality of environment coefficients of the fan under different operation power consumptions.
Generally, for each operation power consumption section, an abscissa may represent each environment temperature section, an ordinate represents each actual fan speed, in a quadrant formed by the above abscissa and ordinate, a fan actual speed straight line of the network device in the current operation state is drawn, and after each operation power consumption is drawn, referring to fig. 5, a plurality of straight lines may be obtained.
In the implementation process, in order to obtain the corresponding environment coefficient, the current environment temperature and the current operation state need to be determined, that is, the corresponding environment coefficient is searched according to the current environment temperature and the current operation state. And still explaining the straight lines, searching the corresponding straight lines according to the current running state, and obtaining the slope of the straight lines determined by the current environment temperature after the current environment temperature of the abscissa is determined, so as to obtain the corresponding environment coefficients.
In other embodiments, after the environmental temperature interval, the operating power consumption interval, the actual fan speed, and the environmental coefficient are all determined, they may be represented in the form of a table, and correspondingly, in the process of determining the environmental coefficient, they may be obtained by directly looking up the table according to the current environmental temperature and the current operating state.
Step 2012: and determining an actual minimum rotating speed value in the actual rotating speeds of the fans based on the environment coefficient.
In the implementation process, after the environmental coefficient is obtained, the actual minimum rotating speed value in the actual rotating speeds of the fans is further determined.
Still explaining by the straight line, according to the current operating state, searching for the corresponding straight line, and after obtaining the corresponding environmental coefficient by solving the slope of the straight line determined by the current environmental temperature, further searching for the actual rotating speed of the fan corresponding to the lowest value of the straight line in the environmental temperature range, which is the actual minimum rotating speed value.
In other embodiments, after the environmental temperature interval, the operating power consumption interval, the actual fan speed and the environmental coefficient are determined, the environmental temperature interval, the operating power consumption interval, the actual fan speed and the environmental coefficient may be represented in the form of a table or the like.
Step 2013: and taking the actual minimum rotating speed value and the environmental coefficient as first speed regulating parameters of the fan.
In the implementation process, the actual minimum rotating speed value and the environmental coefficient are both used as the first speed regulating parameter of the fan. For convenience of candidate operation, use V min The actual minimum rotation speed value is shown, and the environment coefficient is shown by K.
The second mode is as follows: the second speed-regulating parameter of the fan is determined based on the proportional relationship between the current operating state and the preset full-load operating state, as shown in fig. 6, and includes:
step 2011': and acquiring the maximum temperature which can be borne by the power consumption device of the network equipment.
The power consumption device comprises a central processing unit, and further comprises one or more of a memory, a switching chip and an optical module. The power consumption devices are usually the main devices executing data processing tasks in the network device, and when the data amount of the executed data processing tasks is different, the operation power consumption of each power consumption device is also different.
In order to ensure the service life and the service efficiency of each power consumption device, in the implementation process, the maximum temperature which can be borne by the power consumption device of the network equipment is obtained first, so that the working temperature of the power consumption device does not exceed the maximum temperature in the subsequent use process.
In addition, the power consumption coefficient is a performance index representing that the power consumption device corresponds to different actual temperatures under different actual rotating speeds of the fan. Before obtaining the maximum temperature that the power consumption device of the network device can bear, the power consumption coefficient of the network device in each operation power consumption section is obtained, as shown in fig. 7, specifically including:
step 20100': the method comprises the steps of controlling the ambient temperature of the network equipment to be unchanged, controlling the running power consumption of the network equipment to run from no-load power consumption to full-load running state, and respectively collecting the actual rotating speed of each fan and the actual temperature of each power consumption device corresponding to each running power consumption interval from the no-load power consumption to the full-load running state.
Because the environment temperature has an influence on the actual rotating speed of the fan, the environment temperature where the control network device is located is unchanged when the power consumption coefficient is calculated, so that the influence of the environment temperature on the actual rotating speed of the fan is eliminated. And then, controlling the running power consumption of the network equipment to run from the no-load power consumption state to the full-load running state, and correspondingly calculating each running power consumption section from the no-load power consumption state to the full-load running state so as to fully consider the influence of each running power consumption section on the power consumption coefficient.
Furthermore, the corresponding actual rotating speeds of the fans and the actual temperatures of the power consumption devices are respectively collected in each operation power consumption section. For the sake of simple calculation, the above-mentioned each operation power consumption segment may be set in intervals, so that the data amount of the actual rotational speed of each fan and each actual temperature of the power consumption device acquired in this way may also be reduced, and in addition, the actual rotational speed of each fan and each actual temperature of the power consumption device acquired in intervals may also be enough to calculate the power consumption coefficient.
Step 20101': and under the ambient temperature, calculating the power consumption coefficient of the network equipment in each operation power consumption section according to the actual rotating speed of each fan and each actual temperature of each power consumption device.
In the implementation process, under a certain set environmental temperature, the power consumption coefficient of the network equipment in each operation power consumption section is determined according to the ratio of two differences, namely the difference 1 between the actual rotating speeds of the fans and the difference 2 between the actual temperatures of the power consumption devices.
In the implementation process, in order to measure the actual rotation speed of each fan and the actual temperature of each power consumption device in different time periods, the power consumption coefficient can be specifically divided into three. That is, a first power consumption coefficient is calculated by the actual rotation speed of the fan and the actual temperature of the power consumption device in the current time period and the previous time period, respectively, where the first power consumption coefficient is denoted as K p (ii) a Calculating a second power consumption coefficient by the actual rotation speed of the fan and the actual temperature of the power consumption device in the current time period, the previous time period and the previous time period, respectively, wherein the second power consumption coefficient is denoted as K d (ii) a And, passing the current timeCalculating a third power consumption coefficient by actual rotation speed of the fan in the previous time period, actual temperature of the power consumption device in the current time period and an assumed target temperature of the power consumption device in the current time period, wherein the third power consumption coefficient is marked as K i 。
Step 2012': and determining a power consumption coefficient and a preset proportion corresponding to the power consumption device based on the proportional relation between the current operation state and the preset full-load operation state.
In the implementation process, after the maximum temperature that the power consumption device can bear is obtained, the proportional relation between the current operation state of the network device and the preset full-load operation state is calculated, and further, the power consumption coefficients corresponding to the power consumption device, namely the first power consumption coefficient, the second power consumption coefficient and the third power consumption coefficient, are searched according to the proportional relation. And, the appropriate temperature corresponding to the power consumption device under the proportional relationship needs to be correspondingly determined, that is, the preset proportion under the current operation state is determined according to the proportional relationship.
Step 2013': and determining the preset temperature of the power consumption device based on the maximum temperature and the preset proportion, and taking the power consumption coefficient and the preset temperature as a second speed regulation parameter of the fan.
In the implementation process, the preset temperature of the power consumption device, namely the suitable temperature of the power consumption device in the current operation state, is obtained by multiplying the maximum temperature by the preset proportion, so that the corresponding power consumption coefficient and the preset temperature are used as the speed regulation parameters of the fan.
Step 202: the method comprises the steps of calculating a first rotating speed of a fan based on the current environment temperature and a first speed regulating parameter of the network equipment, and calculating a second rotating speed of the fan based on the current device temperature and a second speed regulating parameter of a power consumption device in the network equipment.
Corresponding to the first manner, calculating the first rotation speed of the fan based on the current ambient temperature of the network device and the first speed regulation parameter, as shown in fig. 8, includes:
step 2021: the current ambient temperature of the network device is collected, and a starting ambient temperature of the network device is collected.
Because the current ambient temperature of the network device has a direct influence on the first rotating speed of the fan thereof, for example, when the network device is in an ultra-cold environment (minus thirty degrees centigrade), even if the current operating state of the network device is large, the heat generation amount is large, the temperature can be reduced through the environment, and even the fan does not need to be started. Therefore, in the implementation process, the current ambient temperature of the network device is collected first.
In addition, in the implementation process, the initial environment temperature of the network equipment is also acquired, so that the difference between the current environment temperature and the initial environment temperature is calculated, and the influence of the environment on the network equipment can be measured more accurately.
Step 2022: and determining an environment influence temperature based on the environment coefficient, the current environment temperature of the network equipment and the initial environment temperature, and calculating a first rotating speed of the fan based on the actual minimum rotating speed value and the environment influence temperature.
Obtaining the current environment temperature T K And an initial ambient temperature T min And then, after determining a first speed regulating parameter of the fan according to the proportional relation between the current operation state and the preset full-load operation state in the step 201, determining a corresponding environment coefficient K according to the current environment temperature and the current operation state, and calculating the environment influence temperature T according to the formula (1).
T＝K(T K -T min ) Formula (1)
After calculating the environmental influence temperature, combining the actual minimum rotating speed value V min And an ambient influence temperature, calculating a first rotational speed of the fan according to equation (2).
V K1 ＝V min + T formula (2)
Corresponding to the second manner, calculating the second rotation speed of the fan based on the current device temperature and the second speed-adjusting parameter of the power consumption device in the network device, as shown in fig. 9, includes:
step 2021': the method comprises the steps of obtaining the device temperature of the last time period, the device temperature of the last time period and the current device temperature of the power consumption device in the network equipment in two time periods which are nearest to the current time.
Due to the fact thatIn the real-time operation process of the network equipment, the temperature of the power consumption device changes in real time along with the size of the current operation state. In order to accurately measure the change condition of the power consumption device, the device temperature T of the last time period of the power consumption device in two time periods nearest to the current time period is obtained by taking the current time period as a starting point k-2 Temperature T of the device during the previous period k-1 And the current device temperature T k 。
Step 2022': and acquiring the actual rotating speed value of the fan in the last time period of the fan and the current actual rotating speed value of the fan.
In order to accurately calculate the second rotating speed of the fan, the actual rotating speed value V of the fan in the last time period is acquired in the implementation process k-1 And the current actual rotating speed value V of the fan k 。
Step 2023': the method comprises the steps of calculating device influence temperature based on device temperature, current device temperature and power consumption coefficient of a previous time period, calculating first compensation temperature based on the current device temperature, preset temperature and power consumption coefficient, calculating second compensation temperature based on the device temperature of the previous time period, the current device temperature and the power consumption coefficient, and calculating second rotating speed of a fan based on an actual rotating speed value of the fan of the previous time period, the device influence temperature, the first compensation temperature and the second compensation temperature.
In the implementation process, the temperature T of the device is based on the last time period k-1 Current device temperature T k And a first coefficient of power consumption K p Calculating the device influence temperature T according to the formula (3) p 。
T p ＝K P (T k -T k-1 ) Formula (3)
Based on the current device temperature T k A predetermined temperature T Target And a third coefficient of power consumption K i Calculating a first compensated temperature T according to equation (4) i 。
T i ＝K i (T k -T Target ) Formula (4)
Device based on last time periodTemperature T k-2 Temperature T of the device during the previous period k-1 Current device temperature T k And a second coefficient of power consumption K d Calculating a second compensated temperature T according to equation (5) d 。
T d ＝K d [(T k -T k-1 )-(T k-1 -T k-2 )]Formula (5)
Actual fan rotating speed value V based on last time period k-1 Device influencing temperature T p First compensation temperature T i And a second compensation temperature T d Calculating a second rotation speed V of the fan according to the formula (6) k2 。
V k2 ＝V k-1 +T p +T i +T d Formula (6)
Step 203: the actual rotational speed of the fan is adjusted based on the first rotational speed and the second rotational speed.
In practice, the first rotational speed V is obtained k1 And a second rotational speed V k2 Then, the first rotational speed V is compared k1 And a second rotational speed V k2 And the greater of them, i.e. the first speed V, is selected k1 And a second rotational speed V k2 The actual rotating speed of the fan is adjusted by the larger rotating speed of the fan, so that the actual rotating speed of the fan reaches the first rotating speed V of the larger rotating speed of the fan k1 Or a second rotational speed V k2 。
It should be noted that, since the current operating state of the network device during operation is changed in real time, in order to avoid the situation that the fan speed is difficult to meet the use requirement when the environmental temperature suddenly changes or the power consumption device suddenly increases too much load, it is necessary to set the first speed V at the first speed V k1 And a second rotational speed V k2 And a larger fan rotating speed is selected to ensure the normal operation of the network equipment to the maximum extent.
By adopting the first power consumption coefficient, the second power consumption coefficient and the third power consumption coefficient which can change in a self-adaptive manner, the preset temperature which is more suitable for a use scene can be obtained, and the measured curve relation between the temperature of the power consumption device and the actual rotating speed of the fan is shown in figure 10. However, in the prior art, the first power consumption coefficient, the second power consumption coefficient, the third power consumption coefficient and the preset temperature are all fixed, and then, the measured curve relationship between the temperature of the power consumption device and the actual rotating speed of the fan is shown in fig. 11, as can be seen from the graph, the actual rotating speed of the fan is set to be smaller under the condition that the temperature of the power consumption device is higher, so that the power consumption device can work at a higher temperature for a period of time, and obviously the service life of the power consumption device can be damaged to a certain extent.
