Problems solved by technology

Generally speaking, as the temperature of the device rises, the fan speed is required to be fast, but the fan speed is fast, and the noise is increased. In addition, the fan speed is fast, and the power consumption of the fan itself is also increased.

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] see figure 1 As shown, the embodiment of the present invention provides a method for intelligent fan speed regulation based on device feedback temperature, including the following steps:

[0032] S1. When the system is started, the fan of the device runs at a mid-range speed;

[0033] S2. After the system is started, the device detects the temperature of the device at regular intervals;

[0034] S3, judging whether the current temperature value of the device is correct, if the obtained temperature value is correct, then go to step S5; if the obtained temperature value is wrong, then go to step S4;

[0035] S4. Keep the previous speed of the fan unchanged to avoid speed adjustment errors caused by abnormal temperature sensors. For example, when the temperature range of the device is within 0 to 100 degrees, when the temperatur...

Abstract

The invention discloses an intelligent fan speed regulating method and device based on equipment temperature feedback, and relates to the field of intelligent fan speed regulation. The method includes allowing a fan to operate at medium speed, and detecting temperature at certain intervals; if an acquired temperature value is faulted, keeping the preceding speed of the fan unchanged; if the acquired temperature value is correct, selecting speed regulating modes and speed regulating parameters of the fan; in the stepped speed regulating mode, calculating the fan speed according to the current temperature, initial temperature, a temperature step value and a speed start value, and setting the speed of the fan; in the hysteresis speed regulating mode, if the current temperature is in the operating range of equipment, keeping the preceding speed of the fan unchanged; if the current temperature is higher than the operating temperature of the equipment, allowing the speed of the fan to rise by one grade at certain intervals till to the highest grade or until the equipment temperature decreases to the range of the operating temperature; if the current temperature is lower than the operating temperature of the equipment, executing the step on the contrary. The intelligent fan speed regulating method and device has the advantages that fan noise and power consumption of the equipment can be reduced, the equipment temperature can be reduced, and energy saving and environment protection can be realized.

Description

technical field [0001] The invention relates to the field of fan intelligent speed regulation, in particular to a fan intelligent speed regulation method and device based on equipment feedback temperature. Background technique [0002] As the Internet becomes more and more popular, network equipment can be seen everywhere. Some are installed in the computer room, some are installed on the roadside, some are installed in corridors, some are installed in residential buildings, some are installed in offices, and some are even in users' homes. As the network equipment gets closer to the user, the noise problem of the network equipment becomes more and more prominent. The noise of the network equipment is basically caused by the noise of the equipment fan. Generally speaking, as the temperature of the device rises, the fan speed is required to be fast, but the fan speed is fast, and the noise is increased. In addition, the fan speed is fast, and the power consumption of the fan ...
