摘要
针对电子产品中常用的12V风扇不能根据温度自动调速的问题,本文设计了一种12V风扇自动调速器。文中阐述了以MSP430F2254为核心的风扇调速器的硬件设计和软件设计。该系统具有温度实时检测、温度上下限设置、实时温度显示、人机界面等功能。利用TMP275的I2C接口方式和MSP430F2254的超低功耗,使系统具有低功耗、性能稳定、经济实用等优点。根据不同需要可用于多种电子产品中。
The fan with 12v using in the electronic products can＇t realize automatic speed control,this paper introduces a intellient controller of fan＇s speed based on MSP430F2254.The hardware and software of this instument were introduced particularly.The system has the real-time temperature measurement function, light alarm, real-time temperature display with LED, the human-machine interface,setting the scope of temperature,and may be applied in many electronic products.Using the I2C interface mode of the TMP275 and the ultra-low power of the MSP430F2254, the ultra-low power,stable performance and practicality of the system is realized.
