The intelligent heat dissipation control method of the server IOT can be applied to, for example, the analysis of the operating temperature of the CPU of the server, analyzing the changing trend between the operating temperature of the CPU and the fan module, and controlling When the fan module is running, the fan speed can be reduced to save energy and reduce noise; when the CPU temperature is within the range of the policy value, there is no need to adjust the fan speed.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the sequence of execution, and the execution sequence of each process should be determined by its functions and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

Please refer to FIG. 1 , which is a flowchart of a method for controlling intelligent heat dissipation of a server IOT in a specific embodiment. The method includes:

S101, the server is running, and the running temperature of the CPU is obtained through a temperature sensor;

The operating temperature of the CPU can be obtained through the BMC module in the server. You can obtain the temperature of the CPU at startup, during the running process, and the running temperature of the CPU under different load states, etc.

S102, determining whether the CPU operating temperature obtained in real time is within the first temperature matching threshold;

The first temperature matching threshold may be a temperature matching threshold when the CPU is used between 30% and 50%.

S103. If the first temperature matches the threshold, control the fan module to increase the operating speed to reach the first preset operating speed;

It can be understood that, when the CPU usage rate is lower than 10%, the heat dissipation capacity is lower and the data processing is less, so that the fan module can be operated at a lower speed than the first preset operation speed. If the CPU usage rate is between 30% and 50%, the fan module is controlled to reach the first preset running speed to improve the cooling effect of the CPU.

S104, then obtain the CPU operating temperature to determine whether it is within the first temperature matching threshold;

S105. If yes, the fan module maintains the current running speed.

When the CPU usage rate is between 30% and 50%, and matches within the corresponding first temperature matching threshold, the current operation of the fan module satisfies the requirement.

The relevant data collected and processed by the present invention can be remotely transmitted to the monitoring terminal through the Internet of Things technology for the monitoring personnel to view, and the monitoring personnel can also set the corresponding parameters to meet the use requirements of the server.

Based on the above method, the present invention provides a better cooling control scheme for the server by creating a linkage between the CPU and the fan module, and adjusting the rotation speed of the fan module in real time according to the real-time operating temperature of the CPU. During server operation, the fan module speed is adjusted according to the real-time CPU load, which solves the heat dissipation defect caused by the fixed speed of the current fan module, which can effectively optimize the heat dissipation effect, improve the heat dissipation performance, and save energy and reduce noise.

Further, as shown in FIG. 2, S201, obtain the operating temperature of the CPU through a temperature sensor;

S202. Determine whether the CPU operating temperature obtained in real time is within the second temperature matching threshold; the first temperature matching threshold is greater than the second temperature matching threshold;

That is to say, when the CPU usage rate is lower than 30%, the judgment condition for the CPU matches the second temperature matching threshold.

S203, if the second temperature matches the threshold, controlling the fan module to reduce the operating speed to reach the second preset operating speed;

S204, then obtain the CPU operating temperature to determine whether it is within the second temperature matching threshold;

S205. If yes, the fan module maintains the current running speed.

In this way, during server operation, the fan module speed is adjusted according to the real-time CPU load, which solves the heat dissipation defect caused by the fixed speed of the current fan module, which can effectively optimize the heat dissipation effect, improve the heat dissipation performance, and save energy and reduce noise.

In an embodiment of the present invention, as shown in FIG. 3 , based on the intelligent heat dissipation control method of the server IOT, a possible example will be given below for non-limiting description of its specific implementation.

S301. Obtain the operating temperature of the CPU through a temperature sensor;

S302. Determine whether the CPU operating temperature obtained in real time is within the third temperature matching threshold; the first temperature matching threshold is smaller than the third temperature matching threshold; that is, the CPU usage rate is greater than 50% or higher. The judgment condition for the CPU is matched to the third temperature matching threshold.

S303. If the third temperature matches the threshold, control the fan module to reduce the running speed to reach the third preset running speed; the third preset running speed is equivalent to being higher than the first preset running speed, which increases the fan module running speed.

S304, then obtain the CPU operating temperature to determine whether it is lower than the third temperature matching threshold;

S305. If the temperature is lower than the third temperature matching threshold, the fan module maintains the current running speed.

In the present invention, if the temperature is lower than the third temperature matching threshold and lasts for the first preset time period, indicating that the load of the CPU is reduced, the fan module can be controlled to reduce the speed, and the fan module can be controlled to operate at the first preset speed. run.

As an embodiment of the present invention, the usage rate of the CPU is greater than 50%, or in a fully loaded state, after the fan module runs at the third preset running speed for the second preset duration, if the obtained CPU running temperature is higher than If the third temperature matches the threshold, the fan module is controlled to increase the running speed to reach the fourth preset running speed;

Then obtain the CPU operating temperature to determine whether it is lower than the third temperature matching threshold;

If the temperature is lower than the third temperature matching threshold, the fan module maintains the current running speed.

It can be understood that, at the fourth preset operating speed, the fan module can keep the CPU fully loaded within the third temperature matching threshold, which means that the CPU heat dissipation requirement can be met, and the fan module can maintain the current operating speed. .

If the utilization rate of the CPU decreases and the operating temperature of the CPU also decreases, the speed of the fan module can also be reduced, and then the IOT technology is used to integrate the CPU and the fan module, and combined with an intelligent fan operation strategy to optimize the cooling effect . Implement the IOT technology design scheme and fan operation strategy, improve heat dissipation performance, and ensure the stable operation of the server.

S401. When the server is powered on, the fan module performs a self-check, and adjusts the speed step by step from zero speed to the first preset running speed, and then reduces the speed back to zero, so as to determine whether the fan module is faulty;

S4011. When it is judged that the fan module has no fault, the CPU starts to run.

S4012. If it is determined that the fan module is faulty, an alarm prompt is issued, and the CPU does not start to run.

In order to avoid false alarms, if it is judged that the fan module is faulty, the fan module will be self-checked again until the preset number of times is reached, and if there is still a fault, an alarm will be issued and the CPU will not start running.

This prevents the fan module from failing to run due to failure, or failing to run at the preset running speed, resulting in the inability to effectively dissipate heat to the CPU, which affects the stable operation of the server.
