Problems solved by technology

At present, the general practice of device design in the industry is that when the communication bus between the device management control module and the fan management control module fails, the fan management control module will control the fan to rotate at full speed. Under most usage conditions, the fan module will waste power and generate a lot of noise interference, which is very detrimental to energy saving and environmental protection

[0023] Please refer to figure 1 , figure 1 It is a flowchart of a cooling fan control method provided in the first embodiment of the present invention, the method is applied to a cooling fan control system, the system includes a device management control module and a fan management control module, and the device management control module is connected to the The fan management control module is connected, the fan management control module is used to connect the cooling fan of the device, and the method specifically includes the following steps:

[0024] Step S110: When the communication between the device management control module and the fan management control module is interrupted, the fan management control module obtains the pre-stored historical operation data related to the rotational speed of the cooling fan.

[0025] It can be understood that, in order to avoid the cooling fan running at the maximum speed when the communication between the device management control mod...

[0033] Please refer to figure 2 , figure 2 It is a flow chart of a cooling fan control method provided in the second embodiment of the present invention, and the method specifically includes the following steps:

[0034] S210: When the communication between the device management control module and the fan management control module is in a connected state, the fan management control module acquires the historical operation data related to the rotational speed of the cooling fan.

[0035] As a manner, the fan management control module respectively acquires the historical operation data related to the rotation speed of the cooling fan in each preset time period within a plurality of preset time periods.

[0036] The fan management control module can save the historical operation data obtained above related to the rotation speed of the cooling fan through the rotation speed value register, and use the time register to set and obtain the maximum rotation speed value of the cooli...

[0045] Afterwards, the fan management control module starts to wait until it communicates with the device management control module, and obtains the first batch of control data for controlling the cooling fan speed. Then the fan management control module starts to dynamically collect the rotational speed values ​​stored in the first rotational speed value register R1g, the second rotational speed value register R2g, and the third rotational speed value register R3g in the corresponding time period. If there are multiple sets of cooling fans, the corresponding multiple sets of rotational speed values ​​stored in the first rotational speed value register R1g, the second rotational speed value register R2g, and the third rotational speed value register R3g will be acquired.

[0046] The collection process of the rotational speed values ​​stored in the first rotational speed value register R1g, the second rotational speed value register R2g, and the third rotational spe...

Abstract

The embodiment of the invention provides a control method and system for a heat-dissipating fan and belongs to the technical field of electronic equipment. The method comprises the following steps: when an equipment management control module and a fan management control module are in a cut-off state, the fan management control module acquires historical operating data which is pre-stored and is related to the rotating speed of the heat-dissipating fan; and the fan management control module controls the rotating speed of the heat-dissipating fan based on the historical operating data. Compared with a way of directly controlling operation of the heat-dissipating fan at the maximum rotating speed value all the way when the equipment management control module and the fan management control module are in a cut-off state, the method provided by the invention can save power and reduce noise effectively.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a method and system for controlling a cooling fan. Background technique [0002] In the design of modern large-scale communication equipment, based on the actual needs of application flexibility and operational reliability, the equipment system is often designed to support a multi-service module frame structure, in which the fan system for forced cooling of the equipment will also be designed in a modular manner , and the fan module is sometimes affected by the structural space of the equipment chassis, so it has to be miniaturized and modularized in large quantities. For example, some large-scale data communication equipment in the industry can support more than a dozen fan modules. The function of the fan module on the chassis-type equipment is relatively simple, which is to perform forced air cooling on the series of heating units on the chassis according to the hea...
