However, the communication equipment usually shares the computer room with other automation equipment. There are differences in the environment of the computer room, and the temperature of the computer room cannot fully meet the needs of communication equipment. Especially for seasons or weather with high temperature such as summer, the ambient temperature of communication equipment is relatively high. In order to meet the heat dissipation requirements, fans are usually installed for heat dissipation. For communication equipment that uses fans for heat dissipation, the fan provides airflow from one side of the equipment, and the airflow flows out from the fan on the other side to ensure that the communication equipment can work normally at a suitable temperature, but the fan will inevitably produce noise when it is working. The higher the fan speed , the noise will increase.

In this case, the control of the fan is particularly important. At present, the communication equipment can only be cooled by increasing the fan speed, but most of the time the fan does not need to work at full speed to meet the heat dissipation requirements, and the existing fan speed The control process has a lot of blindness, which will not only cause power waste, but also affect the duty personnel on duty at the substation and nearby residents due to the huge noise generated, increasing the probability of fan failure and causing hidden dangers to the safe operation of the power grid.

Step 1. Determine whether the fan of the communication device is configured. If not, set the fan speed to the maximum fan speed;

Specifically, in this step, when the communication device is powered on for the first time, restarted, or the fan is plugged in but the configuration has not been completed, the fan will be in an out-of-control state, that is, an unconfigured state. Whether the configuration has been completed. If the configuration has not been completed, set the fan speed of the communication device to the maximum fan speed.

Step 2, collecting the temperature of the communication device in real time to obtain the temperature variable of the communication device, the temperature variable=the preset temperature value of the device-the actual temperature value of the device;

Specifically, in this step, for different boards inserted into each slot of the communication device, use different temperature measurement components corresponding to different board types to collect the current temperature of each board, and determine according to the collected temperature of the board The temperature of the communication device, and then the temperature variable of the communication device is obtained.

Step 3, determining the minimum temperature increment of the communication device according to the temperature variable according to a preset cycle;

Step 4, when the minimum temperature increment is less than or equal to the first temperature threshold and the current fan speed is not the maximum fan speed, increase the fan speed;

In this step, the first temperature threshold is 0 degrees Celsius, which can also be set to 1°C. When the minimum temperature increment is less than or equal to the first temperature threshold, it means that the current communication device is relatively normal working temperature. The temperature is too high, and the temperature of the communication device needs to be lowered, and at this time, the speed of the fan needs to be increased;

Further, increasing the rotational speed of the fan may be implemented by increasing a preset fixed value each time.

In this step, the second temperature threshold may be 5 degrees Celsius. When the minimum temperature increment is greater than or equal to the second temperature threshold, it means that the temperature of the current communication device is relatively low compared to the normal working temperature. At this time, for Balanced consideration of factors such as fan power consumption, equipment noise, and normal heat dissipation of communication equipment can appropriately increase the temperature of the communication equipment on the premise of ensuring normal heat dissipation of the communication equipment. , the balance of noise and temperature;

Further, reducing the rotational speed of the fan may be implemented by reducing a preset fixed value each time.
