Detailed Description
The core of the application is to provide a case heat dissipation control method, a case heat dissipation control device, electronic equipment and a computer readable storage medium, so that the rotating speed of a fan can be regulated and controlled more accurately, timely and stably.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Optimization of the heat dissipation scheme is crucial to quality improvement of server products. The rotating speed of the fan is accurately regulated and controlled in real time to meet the heat dissipation requirement of the system, and the method is an important premise for guaranteeing the stable work of the system. However, the current fan speed control strategy in the market is too simple: when the BMC (Baseboard Management Controller) determines that the system temperature reaches a certain temperature threshold, the rotational speed of the cooling fan is adjusted. However, because the operation of the fan has a certain hysteresis, the scheme cannot realize the most accurate and timely regulation and control in many times. In view of this, the present application provides a chassis heat dissipation control scheme, which can effectively solve the above problems.
Referring to fig. 1, an embodiment of the present application discloses a Chassis heat dissipation control method, which is applied to a Chassis Management Controller (CMC), and mainly includes:
s101: and acquiring the temperature value in the case in real time and calculating the temperature change rate.
S102: and predicting the temperature change trend in the case according to the temperature value and the temperature change rate.
S103: and adjusting the rotating speed of a cooling fan of the chassis based on the temperature variation trend.
It will be readily appreciated that a temperature sensor is disposed within the enclosure and is communicatively coupled to the enclosure management controller for transmitting temperature sensing data. However, the temperature is only used as the only index for regulating and controlling the fan, and the heat dissipation state of the whole system is not accurately evaluated.
For example, if the current temperature of the system is low, but the temperature of the system is in a change state of increasing the maximum speed at this time, according to the conventional regulation scheme, if the temperature of the system does not reach the threshold yet and the fan is still controlled to operate at the low speed, when the temperature is quickly increased to a high value (higher than a preset threshold), the rotation speed of the fan is controlled to be quickly increased to the high rotation speed, which causes the current of the fan to increase quickly, which is not beneficial to the life maintenance of the fan, and the problem of untimely regulation of the temperature of the system occurs, and generates a large noise.
Therefore, it should be emphasized that, in the case heat dissipation control method provided in the embodiment of the present application, not only the system temperature detected in real time is used as an index for regulating and controlling the rotation speed of the fan, but also the change rate of the temperature is further calculated and used as an index for regulating and controlling the rotation speed of the fan. It should be noted that the temperature change rate can reflect the change trend of the system temperature, and therefore, the possible system temperature situation in a future period of time can be accurately and effectively predicted by combining the current system temperature and the temperature change rate.
Therefore, the rotating speed of the cooling fan is adjusted according to the current temperature of the system, and the rotating speed of the cooling fan is adjusted according to the temperature change trend on the basis of the current temperature value. So, when finding that temperature variation is very fast, even current temperature has not reached the condition of adjustment rotational speed yet, but what can expect is that the temperature just will exceed the condition of adjustment fan rotational speed very soon, consequently, this application according to the temperature variation trend alright carry out the rotational speed adjustment in advance, on the one hand, can avoid the violent change of fan rotational speed, on the other hand also makes the radiating effect to the system more timely.
Therefore, according to the case heat dissipation control method provided by the application, the current temperature value and the temperature change rate of the system are jointly used as parameter bases for regulating and controlling the rotating speed of the heat dissipation fan, the rotating speed of the heat dissipation fan is timely, effectively and accurately regulated and controlled in advance according to the system temperature value and the temperature change trend, the operation stability of the heat dissipation fan is improved, and the service life of the heat dissipation fan is prolonged.
As a specific embodiment, the method for controlling heat dissipation of a chassis provided in the embodiment of the present application, based on the above, predicts a temperature change trend in the chassis according to a temperature value and a temperature change rate, and includes:
judging whether the temperature value is higher than a preset temperature threshold value or not;
if not, judging whether the temperature change rate is larger than a first preset positive value or not;
if the temperature change rate is larger than a first preset positive value, judging that the current temperature change trend is a low-temperature rising trend;
the rotational speed of radiator fan based on temperature variation trend adjustment machine case includes:
and after the low-temperature rising trend is judged, gradually increasing the rotating speed of the cooling fan.
Specifically, when the current temperature value of the system is lower than the preset temperature threshold, but the chassis management board controller finds that the temperature change rate is high through calculation, that is, the current system temperature is in a low-temperature rising trend, the present embodiment gradually increases the rotation speed of the cooling fan at this time, instead of starting to regulate the rotation speed of the fan after the temperature reaches the preset temperature threshold.
So, this embodiment effectively has avoided radiator fan's rotational speed to suddenly rise fast, the problem that the pump load electric current increases rapidly through promoting radiator fan rotational speed slowly in advance according to the temperature rate of change, has improved the fan life-span greatly, has reduced the fan noise, and is also more accurate to the regulation and control of system's fan simultaneously.
As a specific embodiment, on the basis of the foregoing, the method for controlling heat dissipation of a chassis provided in the embodiment of the present application, after determining that the temperature change rate is not greater than a first preset positive value, further includes:
judging whether the temperature change rate is smaller than a first preset negative value or not;
if the temperature change rate is smaller than a first preset negative value, judging that the current temperature change trend is a low-temperature descending trend;
the rotational speed of radiator fan based on temperature variation trend adjustment machine case includes:
and after the low-temperature descending trend is judged, the rotating speed of the cooling fan is continuously reduced.
Correspondingly, if the current temperature value of the system is lower than the preset temperature threshold value, but the case management board controller finds that the temperature change rate is lower than the first preset negative value through calculation, it indicates that the temperature of the system is maintained at a lower level currently or even in the future, and therefore, in consideration of energy consumption saving, the rotating speed of the cooling fan can be properly adjusted to be lower.
As a specific embodiment, the method for controlling heat dissipation of a chassis provided in the embodiment of the present application further includes, after determining that the temperature value is higher than the preset temperature threshold value, based on the above contents;
judging whether the temperature change rate is smaller than a second preset negative value or not;
if the temperature change rate is smaller than a second preset negative value, judging that the current temperature change trend is a high-temperature descending trend;
the rotational speed of radiator fan based on temperature variation trend adjustment machine case includes:
and after the high-temperature descending trend is judged, gradually reducing the rotating speed of the cooling fan.
Specifically, when the current temperature value of the system is higher than the preset temperature threshold, but the chassis management board controller finds, through calculation, that the temperature change rate is lower than a second preset negative value, that is, the current system temperature is in a high-temperature descending trend, the present embodiment will slowly adjust the rotation speed of the cooling fan at this time, so as to reduce the cooling rate, instead of adjusting the rotation speed of the fan after the temperature is lower than the preset temperature threshold, so as to avoid the sudden and rapid decrease of the rotation speed of the fan.
As a specific embodiment, on the basis of the foregoing, the method for controlling heat dissipation of a chassis provided in the embodiment of the present application, after determining that the temperature change rate is not less than a second preset negative value, further includes:
judging whether the temperature change rate is larger than a second preset positive value or not;
if the temperature change rate is larger than a second preset positive value, judging that the current temperature change trend is a high-temperature rising trend;
the rotational speed of radiator fan based on temperature variation trend adjustment machine case includes:
and after the high-temperature rising trend is judged, the rotating speed of the cooling fan is continuously increased.
Correspondingly, if the current temperature value of the system is higher than the preset temperature threshold value, but the case management board controller finds that the temperature change rate is higher than the second preset positive value through calculation, it indicates that the temperature of the system is maintained at a higher level at the present time or even in a future period of time, and therefore, at this time, the rotating speed of the cooling fan should be properly increased to further increase the cooling power and reduce the temperature in the case as quickly as possible.
Referring to fig. 2, fig. 2 is a schematic view of a chassis heat dissipation control method disclosed in the embodiment of the present application. As a specific embodiment, in the case heat dissipation control method provided in the embodiment of the present application, on the basis of the foregoing, two case management controllers are configured in the case and respectively used as a master controller and a slave controller; the two case management controllers are respectively connected with a Complex Programmable Logic Device (CPLD);
before acquiring the temperature value in the case in real time and calculating the temperature change rate, the method further comprises the following steps:
receiving a control signal sent by a complex programmable controller;
selecting to enter a working state or a standby state according to the control signal; the state control signal is generated by the programmable controller according to the timing heartbeat signals of the two chassis management controllers.
It should be emphasized that, in the conventional single-control temperature adjustment scheme, one enclosure management controller is adopted, so that only one enclosure management controller is provided. When the BMC on the case management controller fails, the CPLD directly takes over and controls the fan to operate at the maximum rotating speed. That is, the full-run control is directly performed without a temperature regulation control strategy configured after the fault of the chassis management controller, so that the noise of the machine is too large, the power consumption is too large, and the stability of the system is not facilitated.
For this reason, the present embodiment adopts a master-slave dual-control heat dissipation regulation strategy, that is, the present application is provided with two chassis management controllers, that is, CMC0 and CMC 1. One of them is a master controller, and the other is a slave controller. The two controllers are respectively in communication connection with the temperature sensor and the CPLD.
Under the general state, the main controller normally regulates and controls the rotating speed of the cooling fan, and the sub-controller is in a standby state. When the master controller fails, the slave controller replaces the original master controller to regulate and control the rotating speed of the cooling fan so as to ensure the normal operation of the whole system. When the worst case occurs, namely when the two chassis management controllers are in failure, the CPLD can control the rotating speed of the fan to be full rotation by the connecting pipe so as to avoid the over-temperature problem of the system.
Specifically, as shown in fig. 2, the CMC0 and the CMC1 adopt an active-standby mode, and the CPLD receives a watchdog signal, which is a timing heartbeat signal, of the two in real time; when the signals can be normally obtained, the CPLD defaults that the master manager and the slave manager work normally, at the moment, the CPLD sends a control 0 signal to enable the CMC0 to be in an active state, namely a working state, and the CMC0 sends a PWM0 signal to the fan to regulate and control the rotating speed in real time according to the read temperature and the temperature change rate obtained through calculation; meanwhile, the CPLD sends a control 1 signal to enable the CMC1 to be in a standby state which is a standby state, and the CPLD does not send a PWM1 signal to the fan by default to regulate and control the rotating speed.
When the CMC0 has a fault, the CPLD cannot acquire a watchdog signal sent by the CMC0, and the CPLD can inform the CMC1 to enter an Active mode, take over the work of the CMC0 and send the PWM1 to the fan to regulate and control the rotating speed in real time. When the user replaces the master control CMC0 with normal functions on line, the CMC0 can normally send a Watchdog signal to the CPLD, and the CPLD receives the signal and switches the CMC0 to an Active mode and the CMC1 to a standby mode.
When the CMC0 and the CMC1 both have faults, the CPLD cannot acquire the watchdog signals sent by the two managers, and at the moment, the CPLD sends a full speed control signal to the fan to enable the fan to rotate at full speed, so that the problem of over-temperature of the machine is avoided.
As a specific embodiment, the method for controlling heat dissipation of a chassis provided in the embodiment of the present application, based on the above content, adjusts a rotation speed of a heat dissipation fan of the chassis based on a temperature variation trend, including:
adjusting the duty ratio of the PWM signal based on the temperature variation trend;
and sending the adjusted PWM signal to the cooling fan.

the acquiring module 201 is configured to acquire a temperature value in the chassis in real time and calculate a temperature change rate;
the prediction module 202 is used for predicting the temperature change trend in the case according to the temperature value and the temperature change rate;
and the adjusting module 203 is used for adjusting the rotating speed of the cooling fan of the chassis based on the temperature change trend.
Therefore, the case heat dissipation control device disclosed in the embodiment of the application uses the current temperature value and the temperature change rate of the system as the parameter basis for regulating and controlling the rotation speed of the heat dissipation fan, and the rotation speed of the heat dissipation fan is timely, effectively and accurately regulated and controlled in advance according to the system temperature value and the temperature change trend, so that the operation stability of the heat dissipation fan is improved, and the service life of the heat dissipation fan is prolonged.
