AI Technical Summary

Technical Problem

In existing technologies, CPLD logic codes only control a single type of fan, resulting in poor compatibility for controlling different types and numbers of fans and high equipment maintenance costs.

Method used

By acquiring the in-situ signal of the mounting plate and the measured temperature, the target device category is identified, the target fan to be connected is determined, and a fan control signal is generated based on the measured temperature. This supports display and control devices with different output channels and enables compatible control of different types and numbers of fans.

Benefits of technology

It improves the compatibility of fan control, reduces development and maintenance costs, and meets the heat dissipation needs of display and control devices with different output channels.

Abstract

The application provides a fan control method and device, CPLD and storage medium, and relates to the technical field of computers, and the method comprises the following steps: obtaining a buckle in-place signal and a measured temperature; the buckle in-place signal is used for representing the number of buckles in a target device; based on the buckle in-place signal, a target device category is identified; the target device category is associated with the number of output lines; based on the target device category, a connected target fan is determined; based on the measured temperature, a fan control signal corresponding to the target fan is determined. The application can meet different fan control scenarios of different types and different numbers of fans corresponding to different output line numbers of target device categories, improve fan control compatibility, reduce development and maintenance costs, and thus reduce device costs.
