摘要
目前,在很多设备中,都存在设备发热问题,而一般情况下,风冷使最常见的散热措施,所在,在大部分设备中,风扇的身影随处可见,而利用PWM信号对风扇转速进行控制,又是最常见的使用方法,所以对此进行研究具有很重要的意义,此外,IIC作为比较常见的通信协议被很多设备使用,本设计通过IIC接口接受主控单元的控制指令,配合本端测温单元,实现对风扇转速的控制和测量。
At present,there are equipment heating problems in many equipment.Generally,air cooling is the most common heat dissipation measure.In most equipment,fans can be seen everywhere,and using PWM signal to control fan speed is the most common method,so it is of great significance to study this.In addition,IIC is used by many devices as a common communication protocol.This design receives the control command of the main control unit through IIC interface and cooperates with the local temperature measurement unit to control and measure the fan’s speed.
