Referring to fig. 3, which is a schematic flow chart of a fan speed regulation method provided in an embodiment of the present invention, and as shown in fig. 3, the embodiment of the present invention shows a process of implementing the fan speed regulation method by a controller:
step S101: and acquiring characteristic information and working current of each heating device, wherein the characteristic information is used for describing the characteristics of the heating device.
The characterization information may include one or more combinations of device type, power consumption of the device, and target temperature. The device type is used to describe the type, specification, and the like of the heat generating device, and in an exemplary embodiment, the device type may include a memory, a CPU, a GPU, and the like, so that the heat generating device can be further distinguished as the memory, the CPU, or the GPU by the device type. The power consumption of the device can be the rated power consumption or the peak power consumption of the heating device, and is used for describing the power consumption condition of the heating device during working. The target temperature is the highest working temperature of the heating device set according to the heat dissipation design of the server, in the specific temperature control, the heating device needs to be controlled not to be higher than the target temperature, and different heating devices can have the same or different target temperatures. Thus, through the characteristic information, the controller can match different current tachometers according to the type of the device in the subsequent steps so as to implement different control strategies aiming at different heat-generating devices.
In addition, in specific implementation, the characteristic information of each heating device can be stored in a register, and the controller acquires the characteristic information of each heating device by accessing the register; the communication method between the controller and the register is not limited, and the access can be performed by an I2C bus.
Step S102: and selecting a current tachometer matched with the characteristic information.
In order to realize the unified management of the current tachometers, a list library of the current tachometers can be established, wherein the list library is used for managing one or more current tachometers, and each current tachometer has a corresponding relation with the characteristic information. For a current tachometer, which is used for describing a heating device for a piece of characteristic information, the corresponding relationship between current and rotating speed is that one current corresponds to one rotating speed.
In specific implementation, according to the overall heat dissipation design of the server system, each heating device needs to be controlled to different target temperatures, that is, each heating device is not higher than the respective target temperature, so as to achieve the overall heat dissipation effect, and different heating devices adopt different control strategies in order to achieve the accurate control of each heating device. In addition, automatic matching of heating devices of different types and specifications can be realized by establishing a current tachometer database, heat dissipation strategies do not need to be established manually one by one, and reusability and flexibility of the speed regulation method are improved.
In a first implementation case, referring to fig. 4, a flowchart of a current tachometer matching method provided in an embodiment of the present invention is shown, and as shown in fig. 4, the method shows a process of implementing flexible speed adjustment of different types of devices according to device types and target temperatures, and the method includes:
step S1021: selecting a set of lists matching the device type from a list library, wherein the list library includes sets of lists corresponding to different device types.
In the embodiment of the present invention, the list library is implemented in the following manner: and the device is divided into a plurality of list sets according to the device type, and each list set is further divided into a plurality of current tachometers according to different target temperatures. As shown in table one, in an exemplary embodiment, the list library includes a GPU list set, a CPU list set, and a memory list set; for the GPU list set, corresponding current tachometers exist for different target temperatures, that is, the GPU-30 current tachometer represents a current tachometer with a target temperature of 30 ℃ for the GPU, the GPU-50 current tachometer represents a current tachometer with a target temperature of 50 ℃ for the GPU, and the GPU-70 current tachometer represents a current tachometer with a target temperature of 70 ℃ for the GPU. This creates a library of lists corresponding to different device types and target temperatures.
Table one:
| set of lists | 30℃ | 50℃ | 70℃ |
| GPU | GPU-30 current tachometer | GPU-50 current tachometer | GPU-70 current tachometer |
| CPU | CPU-30 current tachometer | CPU-50 current tachometer | CPU-70 current tachometer |
| Memory device | Memory-30 current tachometer | Memory-50 current tachometer | Internal memory-70 current tachometer |
Step S1022: and selecting a current tachometer matched with the target temperature from the list set, wherein the list set comprises the current tachometer of the target temperature.
In the matching process, a corresponding current tachometer can be selected according to the device type and the target temperature obtained in the above steps. In an exemplary embodiment, when the device type is CPU and the target temperature is 50 ℃, the CPU list set may be selected, and the CPU-50 current tachometer may be further selected from the CPU list set. Thus, through the process, matching of the current tachometers of all types of heating devices can be realized.
In a second implementation case, referring to fig. 5, the second implementation case is a schematic flow chart of another current tachometer matching method provided in the embodiment of the present invention, and as shown in fig. 5, the method shows a process of implementing flexible speed regulation of heat generating devices of different specifications by power consumption and target temperature of the heat generating device, and the method includes:
step S1023: selecting a set of lists matching the device power consumption from a list library, wherein the list library comprises sets of lists corresponding to different device power consumptions.
Step S1024: and selecting a current tachometer matched with the target temperature from the list set, wherein the list set comprises current tachometers with different target temperatures.
According to the above description of the embodiments, the corresponding current tachometer can be selected by matching the device power consumption and the target temperature. In an exemplary embodiment, when the device power consumption is 20W and the target temperature is 30 ℃, the list set corresponding to 20W may be selected, and the current tachometer corresponding to 30 ℃ may be selected from the list set corresponding to 20W. Therefore, through the process, the matching of the current tachometers of all the power consumption index heating devices can be realized.
In a third implementation case, referring to fig. 6, the third implementation case is a schematic flow chart of a current tachometer matching method provided in an embodiment of the present invention, and as shown in fig. 6, the method shows a process of implementing flexible speed regulation of heat generating devices of different types and specifications by using the type and power consumption of the heat generating device, and the method includes:
step S1025: a first current tachometer is selected that matches the first device type.
Step S1026: and selecting a second current tachometer matched with the type of the second device, wherein the rotating speed difference of the first current tachometer is larger than that of the second current tachometer in the same temperature interval.
The embodiment of the invention shows that a specific current tachometer is configured for heating devices with different power consumptions. In an exemplary embodiment, the first device type is a CPU, the second device type is a memory, and a CPU current tachometer is obtained for the CPU heat generating device according to the first device type and the second device type, as shown in table two, and a memory current tachometer is obtained for the memory heat generating device, as shown in table three. Because the power consumption of the CPU is larger than that of the memory, in an exemplary embodiment, the rotating speed change rate of the heating device aiming at the CPU type is required to be larger than that of the heating device aiming at the memory type, in combination with the second table and the third table, in a current interval of 6A-8A, the rotating speed difference value of the heating device aiming at the CPU is 1000, and the rotating speed difference value of the heating device aiming at the memory is 500, so that the heat dissipation of the device with fast heat accumulation can be accelerated by increasing the current rotating speed adjusting speed, and the power consumption of the device with slow heat accumulation can be saved by reducing the current rotating speed adjusting speed.
Table two:
| current (A) | Rotational speed (turns/second) |
| 8 | 5000 |
| 6 | 4000 |
| 4 | 3000 |
| 2 | 1000 |
Table three:
| current (A) | Rotational speed (turns/second) |
| 8 | 4000 |
| 6 | 3500 |
| 4 | 3000 |
| 2 | 2500 |
It should be noted that the above embodiment is only an exemplary embodiment, and in the specific implementation, the selection may be performed from the current tachometer library by one or more combinations of the device type, the target temperature, and the power consumption of the heat generating device. For example, the corresponding current tachometer is obtained by matching only one of the device type, the target temperature and the power consumption of the heating device, or the current tachometer is selected in a manner of matching the device type, the target temperature and the power consumption of the heating device.
In addition, when the method is implemented specifically, the corresponding current tachometer can be selected according to heating devices with different characteristic information in the same air duct by further combining the design condition of the air duct.
In the first embodiment, when the heat generating devices located in the same air duct are of the same type, the current tachometer with a high target temperature is selected. The first memory 51 and the second memory 52 are located in the same air duct, the device type of the first memory 51 is a memory, the target temperature is 30 ℃, the device type of the second memory 52 is a memory, the target temperature is 50 ℃, and then a current tachometer with the type of the memory and the target temperature of 50 ℃ is selected.
In the second implementation case, when the heating devices in the same air duct are of different types, the current tachometer with high power consumption is selected. When the first processor 61 and the first memory 51 are located in the same air duct, the device type of the first processor 61 is a CPU, the power consumption is 20W, the device type of the first memory 51 is a memory, and the power consumption is 10W, then a current tachometer with the type of the CPU and the power consumption of 20W is selected.
Step S103: and determining the rotating speed corresponding to the working current according to the selected current rotating speed table, and setting the fan corresponding to the heating device as the rotating speed.
In an exemplary embodiment, in combination with the application scenario shown in fig. 2, the first memory 51 and the second memory 52 are located in the same air duct, and the first fan 71 is configured to implement heat dissipation of the first memory 51 and the second memory 52, select a current tachometer with a memory type and a target temperature of 50 ℃ according to the above steps, further select a rotating speed corresponding to the working current from the current tachometer according to the working currents of the first memory 51 and the second memory 52, and control the first fan 71 to operate at the rotating speed.
In another exemplary embodiment, in combination with the application scenario of fig. 2, when the first processor 61 and the first memory 51 are located in the same air duct, the device type of the first processor 61 is CPU, the power consumption is 20W, the device type of the first memory 51 is memory, and the power consumption is 10W, then a current tachometer with the type of CPU and the power consumption of 20W is selected, and the second fan 72 is used to control heat dissipation in the air duct. The corresponding rotation speed is further selected according to the operating current of the heat generating device corresponding to the selected current tachometer, that is, the operating current of the first processor 61, and the second fan 72 is configured at the rotation speed.
As can be seen from the description of the above embodiment, in the speed regulating method for the fan provided by the embodiment of the present invention, the characteristic information and the working current of each heating device are obtained, and the characteristic information is used for describing the characteristics of the heating device; selecting a current tachometer matched with the characteristic information; and determining the rotating speed corresponding to the working current according to the selected current rotating speed table, and setting the fan corresponding to the heating device as the rotating speed.
