Embodiment Construction

[0057] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings.

[0058] see figure 1 , figure 1 It is an application environment diagram in an embodiment. Such as figure 1As mentioned above, the application environment includes a chassis, in which a main fan and a backup fan are installed, and a power supply module is arranged in the chassis, and the power supply module is used as the main power supply to supply power to each module and unit in the chassis, and a control unit is installed in the chassis Processor, the control processor is used to control the equipment in the chassis and communicate with the equipment in the chassis. There are indicator circuits, memory, crystal oscillator circuits, watchdog circuits, backup batteries, etc. in the chassis to assist the equipment and control processing of the chassis device works normally.

[0059] The chassis can b...

Abstract

The invention relates to a fan control system and a backup battery charging method. The fan control system comprises a microprocessor, multiple main fan assemblies and multiple backup fan assemblies.The main fan assemblies and the backup fan assemblies are connected with corresponding external expansion interfaces of the microprocessor correspondingly, the main fan assemblies are connected with multiple main fans in a one-to-one correspondence mode, the backup fan assemblies are connected with backup fans in a one-to-one correspondence mode, and each main fan is at least close to one backup fan. The microprocessor is use for obtaining operation states of the main fans through the main fan assemblies. When the microprocessor judges that any main fan is in a fault state according to the operation state of the main fan, the backup fan adjacent to the main fan is controlled by the corresponding backup fan assembly to be started. According to the fan control system, the backup fan adjacentto the corresponding main fan in the fault state is started, the influences of the main fan in the fault state on cooling can be reduced, and reliability and stability of cooling performance of the fan control system are improved.

Description

technical field [0001] The invention relates to the field of fans, in particular to a fan control system and a backup battery charging method. Background technique [0002] With the improvement of the integration level of electronic products and the increase of power consumption, the heat dissipation performance requirements of electronic products also increase accordingly. [0003] Multi-fan heat dissipation is a conventional method to solve the air waste heat inside the equipment chassis. Multi-fan heat dissipation generally uses the same control signal to control multiple fans. [0004] However, when an error occurs in the control signal, the fans controlled by the same control signal will stop working, which will reduce the heat dissipation performance of the multi-fan heat dissipation. Especially when all the fans are controlled by a unified control signal, any error in the control signal will cause all the fans to stop working, and the cooling performance of multi-fa...
