The temperature sensor can be one or more and is arranged at a position needing to be detected in the machine room.
Specifically, the algorithm for controlling the rotational speed may be selected as desired. For example, if the temperature at the designated position is increased, the rotation speed of the floor of the EC fan is increased, and the rotation speed increase is calculated by: and calculating the temperature difference value of the specified positions at the current moment and the previous moment, and multiplying the temperature difference value by a preset coefficient to be equal to the variable quantity of the increased rotating speed.

The EC fan floor is linked with the hot area on the back of the cabinet through the controller, and the temperature change of the hot area of the cabinet is dynamically acquired, so that the rotating speed condition of the EC fan floor is dynamically adjusted. For example, the speed of the EC fan floor may be increased when the cabinet hot zone temperature increases, and the speed of the EC fan floor may be decreased when the cabinet hot zone temperature decreases.
When the designated position is the cold channel of the machine room, the temperature sensor is used for detecting the temperature in the cold channel of the machine room. The EC fan floor is linked with the cold channel temperature and humidity probe through the controller, and the temperature change in the cold channel is dynamically acquired, so that the rotating speed condition of the EC fan floor is dynamically adjusted. For example, when the temperature in the cold aisle increases, the rotation speed of the EC fan floor is increased, and when the temperature in the cold aisle decreases, the rotation speed of the EC fan floor is decreased.

s200: and controlling the rotating speed of the floor of the EC fan according to the detected temperature of the specified position.
Specifically, the algorithm for controlling the rotational speed may be selected as desired. For example, if the temperature at the designated position is increased, the rotation speed of the floor of the EC fan is increased, and the rotation speed increase is calculated by: and calculating the temperature difference value of the specified positions at the current moment and the previous moment, and multiplying the temperature difference value by a preset coefficient to be equal to the variable quantity of the increased rotating speed. If the temperature of the designated position is reduced, reducing the rotating speed of the floor of the EC fan, wherein the rotating speed reduction is calculated in the following mode: : and calculating the temperature difference value of the specified position at the current moment and the previous moment, and multiplying the temperature difference value by a preset coefficient to be equal to the variable quantity of the reduction of the rotating speed.
Further, a mapping relation between the designated position and the floor of the EC fan can be established. For example, the temperatures of two designated positions are detected, two EC fan floors are controlled, and the designated positions and the EC fan floors are in one-to-one correspondence. And controlling the rotating speed of the first EC fan floor according to the temperature change of the first appointed position, and controlling the rotating speed of the second EC fan floor according to the temperature change of the second appointed position.

In this embodiment, in step S100, detecting the temperature at a specific position in the machine room includes the following steps:
detecting the temperature of a hot aisle of the machine room and/or detecting the temperature in a cold aisle of the machine room.
Specifically, the EC fan floor is linked with a hot area at the back of the cabinet to dynamically acquire temperature changes of the hot area of the cabinet, thereby dynamically adjusting the rotation speed of the EC fan floor. For example, the speed of the EC fan floor may be increased when the cabinet hot zone temperature increases, and the speed of the EC fan floor may be decreased when the cabinet hot zone temperature decreases. The floor of the EC fan is linked with the temperature and humidity probe of the cold channel, and the temperature change in the cold channel is dynamically acquired, so that the rotating speed condition of the floor of the EC fan is dynamically adjusted. For example, when the temperature in the cold aisle increases, the rotation speed of the EC fan floor is increased, and when the temperature in the cold aisle decreases, the rotation speed of the EC fan floor is decreased.
