Embodiment 1

[0054] Embodiment 1. The above-mentioned gear position prediction model is: a state conversion weight table for recording the weights of the conversion between the states of the above-mentioned working environment, wherein the state of the above-mentioned working environment includes: the temperature collected by the temperature sensor and the working temperature of the fan stalls.

[0055] The higher the weight of transition between two states of the working environment, the higher the probability of transition between these two states, that is, the greater the possibility of transition between these two states.

[0056] In this case, the above step S102 takes the current temperature and the current gear as model input, and predicts the gear after the speed regulation of the fan according to the gear prediction model obtained in advance, including:

[0057] S102A: Query the state transition weight table, and obtain the second state with the highest weight when performing stat...

Embodiment 2

[0165] Embodiment 2. The above gear position prediction model is a neural network model.

[0166] In this case, the gear prediction model is a neural network model;

[0167] The gear prediction module 502 includes:

[0168] A reward obtaining unit, configured to input the first state of the working environment into the neural network model, and obtain the working environment predicted by the neural network model that the fan works in each gear in the first state. The reward brought, wherein, the first state is: a state including the current temperature and the current gear;

[0169] The second gear position determination unit is used for determining the gear position corresponding to the highest reward as the gear position of the fan after speed regulation for each fan.

[0170] Those skilled in the art can understand that when the number of temperature sensors is large and the number of fans is also large, the number of states of the above-mentioned working environment incl...

Abstract

The embodiment of the invention provides a fan speed control method and device, and relates to the technical field of device control. The method includes the steps: obtaining a current temperature collected by a temperature sensor which monitors the device working environment temperature, and obtaining a current gear position of a fan which adjusts the working environment temperature; using the current temperature and the current gear position as a model input, and predicting the fan speed-adjusted gear position according to the gear position prediction model obtained by pre-training, specifically, the gear position prediction model is obtained by taking the temperature collected by the temperature sensor and the gear position of the fan as status, and adjusting the gear position of the fan as the action for strengthened training, and is used for predicting the fan speed-adjusted working gear position; and adjusting the fan speed according to the fan speed-adjusted gear position. The method can adjust the fan speed flexibly.

Description

technical field [0001] The present application relates to the technical field of equipment control, in particular to a fan speed regulation method and device. Background technique [0002] As the business volume increases and the running time becomes longer, the CPU, MAC (Media Access Control, Media Access Control) and other chips in network devices such as switches and routers will continue to generate heat. High, if the heat is not dissipated in time, it will affect the normal operation of each chip, and even cause the chip to burn out. [0003] In the prior art, a plurality of temperature sensors are generally installed in the network equipment, and the temperature collected by each temperature sensor is monitored, and the speed of the fan is controlled according to the temperature collected by the temperature sensor, so as to achieve the purpose of heat dissipation. [0004] At present, the staff usually set the maximum speed regulation threshold temperature H and the m...
