智能单片机电风扇的设计论文.doc

摘要 本设计主要介绍了一种智能电风扇的设计方案。该系统以单片机为核心，应用Motorola的电场传感器MC33794和加速度MNA1260D，为风扇提供了多方位的保护，也为用户提供了更智能化的管理。 本设计采用的温度智能控制，使风扇可以感知环境的温度，以调节风扇的转速，达到更好的工作效果。用户可以选择这种智能调速的方式，也可以选择手动设定方式来控制转速。当选择手动设定方式时，该功能不发挥作用。智能照明功能，在晚间当，用户接近风扇时候，风扇能够探测到人体的接近，从而启动微光照明，方便用户操作并避免用户和风扇或其他物体发生不必要的碰撞。而定时工作功能可以让用户自己定制风扇工作时间的长短，以提供更人性化的服务。液晶显示功能使用液晶屏显示当前室温度，风扇的转速，风扇的工作模式，当前时间，风扇工作时间等参数，美观大方。 关键词：智能，电风扇，电场传感器，加速度，接近检测 ABSTRACT This design mainly introduced one kind of intelligent electric fan design proposal. This system take the monolithic integrated circuit as a core, applies Motorola electric field sensor MC33794 and acceleration MNA1260D, has provided the multi- positions protection for the ventilator, also has provided a more intellectualized management for the user. This design uses the temperature intelligence control, enables the ventilator to be possible the sensation environment temperature, by adjusts the ventilator the rotational speed, achieves the better work effect. The user may choose this kind of intelligent velocity modulation the way, also may choose the manual hypothesis way to control the rotational speed. When chooses the manual hypothesis way, this function does not play the role. The intelligent illumination function, works as in the evening, the user approaches ventilator time, the ventilator can survey to human body approaching, thus the start glimmer illumination, the convenient user operates and avoids the user and the ventilator or other objects has the nonessential collision. But fixed time works the function to be possible to let user have custom-made the ventilator operating time operating time the length, by provides the personal service. The liquid crystal display function use liquid crystal screen demonstrates the current room temperature, the ventilator rotational speed, the ventilator working pattern, current time, parameter and so on ventilator operating time operating time, elegant appearance.
