Embodiment 1

[0083] like figure 1 As shown, the present invention provides a fan regulation method for fuzzy control of multiple temperature sensors, comprising the following steps:

[0084] S1. BMC obtains the required fuzzy rules from the fuzzy rule base; the fuzzy rules include front temperature conditions and rear speed conclusions;

[0085] S2. The BMC obtains the readings of each temperature sensor, and calculates the readings of each temperature sensor as the input to the membership degree of the temperature conditions in front of each fuzzy rule;

[0086] S3. The BMC obtains the fuzzy operators of each fuzzy rule respectively, and then uses the corresponding membership degrees of the temperature conditions in the front of the fuzzy rules as inputs, and calculates the membership degrees of the temperature conditions in the front of the fuzzy rules through the fuzzy operators to obtain the fuzzy The weight of the temperature condition at the front of the rule;

[0087] S4. BMC appl...

Abstract

The invention provides a fan regulation and control method and device for conducting fuzzy control on multiple temperature sensors, and belongs to the technical field of fan regulation and control. Obtaining the reading of each temperature sensor, and calculating the membership degree of each temperature to the front temperature condition of the rule; obtaining a fuzzy operator of each fuzzy rule, and carrying out operation on each membership degree of the front temperature condition of the fuzzy rule to obtain a weight of the front temperature condition of the fuzzy rule; the weights of the front temperature conditions of all the fuzzy rules are applied to the rear rotating speed conclusion of the same fuzzy rule, curves of the rear rotating speed conclusion are obtained, all the curves are combined, and a fuzzy set of all the fuzzy rules is obtained; and performing defuzzification on the curves of all the fuzzy rules to obtain the rotating speed of the fan, and adjusting the rotating speed of the fan. The fan rotating speed is directly calculated according to the temperature by using the fuzzy control algorithm, so that the problem of CPU downtime caused by untimely temperature control is avoided.
