Problems solved by technology
[0003] Most of the existing DC fan protection schemes are to add a current impact protection circuit at the front of the DC fan. The damage of most DC fans is not directly caused by one-time overvoltage or overcurrent, but the fan speed is out of control due to unknown interference and other factors. , this state will keep rotating at high speed and full speed until the fan is short-circuited and burned
When the fan is short-circuited, it will cause the Mosfet+FUSE circuit of the protection circuit to burn out
Therefore, the current surge protection circuit for this phenomenon cannot solve such problems
The monitoring of the DC fan is not perfect and when the DC fan is out of control, when there is continuous overcurrent, the protection circuit does not play a protective role because the overcurrent protection point is not triggered, and it burns out its own circuit, which brings great influence to the follow-up problem analysis. challenge

The invention discloses a fan control method. The fan control method comprises the following steps that the real-time current of a fan is detected; responding to the condition that the real-time current of the fan meets a preset condition in a first preset time period and does not exceed an overcurrent protection threshold value, generating fan first control information and sending the fan first control information to a fan controller; the fan controller controls the fan to stop rotating for a second preset time based on the first control signal; and responding to the second control information received by the fan controller, and restarting the fan. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, the technical purposes of preventing the fan from being burnt when the fan is out of control and preventing relevant protection circuits of the MOSFET and the FUSE can be achieved, and fan fault isolation and fan fault self-repair can be automatically achieved without manual maintenance.
Description
technical field [0001] The present invention relates to the field of servers, in particular to a fan control method, system, device and storage medium. Background technique [0002] In server systems, a stable and reliable fan system is the basis for stable server operation. If there is no perfect DC fan fault protection and automatic recovery system, the fan will face short-circuit burnout and burnout of related protection circuits (switch Mosfet+fuse), and it will also bring serious challenges to fan fault analysis. [0003] Most of the existing DC fan protection schemes are to add a current impact protection circuit at the front of the DC fan. The damage of most DC fans is not directly caused by one-time overvoltage or overcurrent, but the fan speed is out of control due to unknown interference and other factors. , this state will keep rotating at high speed and full speed until the fan is short-circuited and burned. When the fan is short-circuited, it will cause the Mo...
