摘要传统的电风扇档位比较固定,当气温变化之后就需要再次调节电风扇的档位十分麻烦。而且当晚上人们进入睡眠时,夜晚的气温变得比较低,如果电扇一直保持较大的风速档位,老人和孩童体质较弱很容易感冒生病,所以本次的毕业设计是对于风扇系统的优化与智能控制,能让用户更加直观的可拿到当前的温度。95170
相比于传统风扇,利用STC89C52单片机控制并且使用温度传感器的智能风扇系统更加的人性化。可以适应温度的改变风速,让用户拥有更加良好的体验,而且还能够设定最高温度和最低温度,让风扇系统达到不同的档位,提供不同的风速,当外界温度低于设定温度时,风扇会自动关闭,从而满足不同用户的需求。设计中加入了无线遥控功能,让操控起来更加的方便。
Abstract The traditional fan stalls relatively fixed, when the temperature changes after the need to adjust the fan again gear is very troublesome。 And when people get into sleep at night, the night temperature becomes relatively low, if the fan has been to maintain a large wind speed stalls, the elderly and children are weak and vulnerable to illness, so this graduation design is for the fan system optimization And intelligent control, allowing users to more intuitive to get the current temperature。
Compared to traditional fans, the use of STC89C52 single-chip control and the use of temperature sensors intelligent fan system more humane。 Can adapt to the temperature change the wind speed, allowing users to have a better experience, but also to set the maximum temperature and minimum temperature, so that the fan system to achieve a different gear, providing different wind speed, when the outside temperature is lower than the set temperature, The fan will automatically shut down to meet the needs of different users。 Designed to join the wireless remote control function, so that control more convenient。
Key words: Wireless communication; Temperature control speed; Pulse width modulation
