Problems solved by technology

The existing heat dissipation method of partition speed regulation has the following defects: the fan partition will lead to a large number of controls at the same time, resulting in the adjustment of the fan speed not smooth enough; most of the fan output power is useless, wasting energy and generating large noise; a monitoring board is required For the overall control of the fan, if the monitoring circuit fails, the fan speed can no longer be adjusted normally

Abstract

The invention provides a fan speed regulation system and method. The system comprises a monitoring board, a signal backboard, at least one temperature sensor array, at least one fan assembly plate and at least one fan array, wherein the monitoring board, the temperature sensor arrays and the fan assembly plates are in communication connection with the signal backboard; each fan assembly plate is in communication connection with the corresponding fan array; the monitoring board or each fan assembly board is used for calculating the rotating speed of the corresponding fan array according to temperature information and a preset speed regulation mode and generating corresponding rotating speed control information; the signal backboard is used for transmitting the information; each temperature sensor array is used for collecting temperature information of a single board in network equipment; each fan assembly plate is further used for adjusting the rotating speed of each fan in the corresponding fan array according to the rotating speed control information; and the fan arrays are used for cooling the network equipment.

Description

technical field [0001] The present application relates to the technical field of system heat dissipation of network equipment, in particular to a fan speed regulation system and method. Background technique [0002] With the continuous improvement of network throughput, the power consumption of service cards of large-capacity network devices (such as switch devices, etc.) is increasing, and the demand for heat dissipation is also increasing. At present, most network devices mainly use fans to dissipate heat, and use fans or fan arrays to dissipate heat through specific air outlet channels. [0003] At present, the heat dissipation of fan arrays mainly adopts the heat dissipation method of speed regulation by partition. Specifically, the network device obtains the ambient temperature of the line card and the temperature of the chip through the monitoring board, integrates the ambient temperature of the whole machine, and adjusts the overall speed of the fans in the correspon...
